Instalasi Qmail, Vmailmgr, Omail Admin, Courier Imap, dan Squirrelmail

1. Instalasi Qmail
Sebelum memulai, silakan anda uninstall software mailserver (MTA) lain yang berada dalam server anda misalnya sendmail, dan silakan anda membuat sebuah direktori temporari untuk memudahkan penyimpanan source yang akan didownload, anda boleh membuat direktori dengan nama sembarang, disini saya membuat direktori dengan nama src :
[root@wedus asfik]# service sendmail stop
[root@wedus asfik]# for a in `rpm -qa grep sendmail`; do rpm -e –nodeps $a; done
[root@wedus asfik]# mkdir src
[root@wedus asfik]# cd src
Download qmail dan paket pendukung yang lain (daemontools, ucspi-tcp) :
[root@wedus src]# wget http://cr.yp.to/software/qmail-1.03.tar.gz
[root@wedus src]# wget http://cr.yp.to/ucspi-tcp/ucspi-tcp-0.88.tar.gz
[root@wedus src]# wget http://cr.yp.to/daemontools/daemontools-0.76.tar.gz
Perhatian : Jika anda menggunakan glibc versi 2.3 keatas (misalnya Redhat 9), silakan download patch untuk qmail dari miror lokal kesayangan anda misalnya dari ISP CBN :
[root@wedus src]# wget http://qmail.cbn.net.id/moni.csi.hu/pub/glibc-2.3.1/qmail-1.03.errno.patch
[root@wedus src]# wget http://qmail.cbn.net.id/moni.csi.hu/pub/glibc-2.3.1/ucspi-tcp-0.88.errno.patch
[root@wedus src]# wget http://qmail.cbn.net.id/moni.csi.hu/pub/glibc-2.3.1/daemontools-0.76.errno.patch
Download qmailqueue-patch, yang berguna sebagai add-on qmail agar bisa menjalankan external program, misalnya jika anda menginginkan software anti-virus serta quotas-patch, yang berguna untuk membounce email jika suatu user sistem sudah melebihi quota sistem, misalnya untuk pemberian quota perdomain dengan vmailmgr
[root@wedus src]# wget http://www.qmail.org/qmailqueue-patch
[root@wedus src]# wget http://www.qmail.org/qmail-1.03-quotas-1.1.patch
Ekstrak semua source tersebut :
[root@wedus src]# tar -xzvf qmail-1.03.tar.gz
[root@wedus src]# tar -xzvf daemontools-0.76.tar.gz
[root@wedus src]# tar -xzvf ucspi-tcp-0.88.tar.gz
Buat direktori untuk qmail dan pembuatan account user yang akan menjalankan dan mengurusi qmail :
[root@wedus src]# mkdir /var/qmail
[root@wedus src]# groupadd nofiles
[root@wedus src]# useradd -g nofiles -d /var/qmail/alias alias
[root@wedus src]# useradd -g nofiles -d /var/qmail qmaild
[root@wedus src]# useradd -g nofiles -d /var/qmail qmaill
[root@wedus src]# useradd -g nofiles -d /var/qmail qmailp
[root@wedus src]# groupadd qmail
[root@wedus src]# useradd -g qmail -d /var/qmail qmailq
[root@wedus src]# useradd -g qmail -d /var/qmail qmailr
[root@wedus src]# useradd -g qmail -d /var/qmail qmails
Kompilasi qmail, daemontools, tcpserver dan mengepatch qmail dengan beberapa patch tersebut diatas :
[root@wedus src]# cd qmail-1.03
Perhatian : Jika anda menggunakan glibc versi 2.3 keatas (misalnya Redhat 9), patch qmail anda :
[root@wedus qmail-1.03]# patch -p1 < ../qmail-1.03.errno.patch
Jika diperlukan, patch qmail anda dengan queue patch dan quota patch :
[root@wedus qmail-1.03]# patch -p1 < ../qmailqueue-patch
[root@wedus qmail-1.03]# patch -p1 < ../qmail-1.03-quotas-1.1.patch
Kompile dan install qmail :
[root@wedus qmail-1.03]# make setup check
Membuat file konfigurasi qmail, disini silakan anda ganti gibas.wedus.comdengan hostname anda yang FQDN (bisa diresolve), misalnya serverku.domain.com.Ingat, hostname tidak harus sama dengan nama server host tempat anda menginstall qmail tersebut.
[root@wedus qmail-1.03]# ./config-fast gibas.wedus.com
[root@wedus qmail-1.03]# cd ../ucspi-tcp-0.88
Perhatian : Jika anda menggunakan glibc versi 2.3 keatas (misalnya Redhat 9), patch ucspi-tcp anda :
[root@wedus ucspi-tcp-0.88]# patch -p1 < ../ucspi-tcp-0.88.errno.patch
Kompile dan install ucspi-tcp :
[root@wedus ucspi-tcp-0.88]# make setup check
[root@wedus ucspi-tcp-0.88]# cd ../admin/daemontools-0.76/
Perhatian : Jika anda menggunakan glibc versi 2.3 keatas (misalnya Redhat 9), patch daemontools anda :
[root@wedus daemontools-0.76]# patch -p1 < ../../daemontools-0.76.errno.patch
Kompile dan install daemontools :
[root@wedus daemontools-0.76]# ./package/install
Jika daemontools sukses terinstal, anda bisa mengecek dengan menggunakan perintah ps, misalnya :
[root@wedus daemontools-0.76]# ps ax grep read
6529 ? S 0:00 readproctitle service errors: …………………..
Saya kurang suka dengan struktur penempatan atau symlink file dan direktori pada daemontools dan (menurut saya lho) cenderung amburadul, jadi direktori /command saya hapus kemudian diganti dengan direktori command dari source daemontools :
[root@wedus daemontools-0.76]# rm -rf /command/
[root@wedus daemontools-0.76]# mv command/ /
Buat file startup untuk menjalankan qmail-send, dan mengganti defaultdelivery dari format Mailbox ke format Maildir :
[root@wedus asfik]# cp /var/qmail/boot/home /var/qmail/rc
[root@wedus asfik]# perl -pi -e “s/Mailbox splogger qmail/Maildir\//g” /var/qmail/rc
Jika perintah perl tersebut diatas ada kesalahan atau linux ada tidak terinstall program perl (sulit dipercaya?), silakan secara manual anda mengganti pada file /var/qmail/rc dari baris ini :
qmail-start ./Mailbox splogger qmail
menjadi :
qmail-start ./Maildir/
Buat direktori untuk menyimpan file-file supervise :
[root@wedus asfik]# mkdir -p /var/qmail/supervise/qmail-send/log
[root@wedus asfik]# mkdir -p /var/qmail/supervise/qmail-smtpd/log
Buat file script supervise untuk menjalankan qmail-send :
[root@wedus asfik]# vi /var/qmail/supervise/qmail-send/run
Isinya :
#!/bin/sh
exec /var/qmail/rc
Buat file script supervise untuk menjalankan log qmail-send :
[root@wedus asfik]# vi /var/qmail/supervise/qmail-send/log/run
Isinnya :
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t s1048576 /var/log/qmail
Buat file script supervise untuk menjalankan qmail-smtpd :
[root@wedus asfik]# vi /var/qmail/supervise/qmail-smtpd/run
Isinya :
#!/bin/sh
PATH=$PATH:/usr/local/bin:/var/qmail/bin
export PATH
QMAILDUID=`id -u qmaild`
NOFILESGID=`id -g qmaild`
MAXSMTPD=30
exec /usr/local/bin/softlimit -m 5000000 tcpserver -H -R -v -x /etc/tcp.smtp.cdb -c “$MAXSMTPD” -u “$QMAILDUID” -g “$NOFILESGID” 0 25 qmail-smtpd 2>&1
Variabel MAXSMTPD bisa anda sesuaikan dengan kondisi kebutuhan dan beban mailserver anda. Jika anda menginginkan penolakan terhadap email yang datang dari mailserver yang open relay yang biasanya merupakan SPAM, anda bisa menggunakan rblsmtpd menjadi :
tcpserver -H -R -v -x /etc/tcp.smtp.cdb -c “$MAXSMTPD” -u “$QMAILDUID” -g “$NOFILESGID” 0 25 rblsmtpd -r relays.ordb.org rblsmtpd -b qmail-smtpd 2>&1
Jika anda menggunakan rblsmtpd, anda nanti bisa melihat lognya di /var/log/qmail/smtpd/current :
[root@wedus asfik]# tail -f /var/log/qmail/smtpd/current
@400000003dbca93728ec47bc tcpserver: pid 11461 from 128.154.20.228
@400000003dbca93804e39064 rblsmtpd: 128.154.20.228 pid 11461: 451 This mail was handled by an open relay – please visit
Buat file script supervise untuk menjalankan log qmail-smtpd :
[root@wedus asfik]# vi /var/qmail/supervise/qmail-smtpd/log/run
Isinya :
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t s1048576 /var/log/qmail/smtpd
Ubah menjadi file-file yang bisa dieksekusi :
[root@wedus asfik]# chmod 755 /var/qmail/supervise/qmail-send/run
[root@wedus asfik]# chmod 755 /var/qmail/supervise/qmail-send/log/run
[root@wedus asfik]# chmod 755 /var/qmail/supervise/qmail-smtpd/run
[root@wedus asfik]# chmod 755 /var/qmail/supervise/qmail-smtpd/log/run
Buat direktori untuk log qmail-send dan qmail-smtpd :
[root@wedus asfik]# mkdir -p /var/log/qmail/smtpd
[root@wedus asfik]# chown qmaill /var/log/qmail /var/log/qmail/smtpd
Mengijinkan localhost untuk menggunakan smtp :
[root@wedus src]# echo ‘127.0.0.1:allow,RELAYCLIENT=”"‘ > /etc/tcp.smtp
Mengatur IP/Network mana saja yang bisa menggunakan smtp server anda, jika misalnya anda menginginkan komputer di jaringan intranet anda dengan IP 10.126.10.11 bisa menggunakan smtp anda, maka :
[root@wedus src]# echo ‘10.126.10.11:allow,RELAYCLIENT=”"‘ >> /etc/tcp.smtp
Atau jika anda mengijinkan seluruh network anda, misalnya 10.126.10.0/24 maka :
[root@wedus src]# echo ‘10.126.10.:allow,RELAYCLIENT=”"‘ >> /etc/tcp.smtp
Jangan lupa, setiap selesai penambahan untuk selalu membuat database baru dengan :
[root@wedus src]# tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp
Akhirnya kita masukkan script yang kita buat kedalam servis supervise :
[root@wedus asfik]# ln -s /var/qmail/supervise/qmail-send /var/qmail/supervise/qmail-smtpd /service
Untuk mengecek apakah supervise sudah menjalankan tugasnya dengan benar bisa digunakan perintah ps, misalnya :
[root@wedus asfik]# ps ax grep qmail
6636 ? S 0:00 supervise qmail-send
6638 ? S 0:00 supervise qmail-smtpd
6640 ? S 0:00 qmail-send
6641 ? S 0:00 /usr/local/bin/multilog t s1048576 /var/log/qmail
6643 ? S 0:00 /usr/local/bin/multilog t s1048576 /var/log/qmail/smt
6644 ? S 0:00 qmail-lspawn ./Maildir/
6646 ? S 0:00 qmail-rspawn
6647 ? S 0:00 qmail-clean
Untuk sekedar memastikan, anda juga bisa telnet ke localhost port 25 :
[root@wedus src]# telnet localhost 25
Trying 127.0.0.1…
Connected to localhost.
Escape character is ‘^]’.
220 gibas.wedus.com ESMTP
Jika sampai langkah ini, anda belum sukses atau menemui error, coba periksa sekali lagi apakah penulisan script anda sudah betul dan tidak kurang, atau apakah ada langkah/perintah yang anda lewatkan. Anda juga bisa melihat kemungkinan pesan kesalahan/error pada file log /var/log/qmail/current atau /var/log/qmail/smtpd/current atau bisa juga pada proses readproctile, misalnya, dalam kondisi normal:
[root@wedus src]# ps ax grep read
673 ? S 0:00 readproctitle service errors: …………………..
Jika ada sesuatu error/kesalahan pada servise supervise, misalnya jika sebuah command `id` tidak diketemukan karena kesalahan environment $PATH:
[root@wedus src]# ps ax grep read
673 ? S 0:00 readproctitle service errors: …….?\id…?\command..\?not…found
PENTING. Untuk menerima email bounce ke postmaster silakan anda buat minimal tiga buah email sebagai berikut :
[root@wedus src]# cd ~alias/
[root@wedus alias]# echo paijo@sapi.net > .qmail-root
[root@wedus alias]# echo paijo@sapi.net > .qmail-postmaster
[root@wedus alias]# echo paijo@sapi.net > .qmail-mailer-daemon
Ganti paijo@sapi.net dengan email yang bertanggung jawab terhadap server email tersebut (anda?)
2. Instalasi Vmailmgr
Alasan pribadi saya kenapa memilih vmailmgr dibandingkan dengan vpopmail adalah saya kurang suka struktur direktori penempatan domain di vpopmail yang menyimpan semua domain dalam satu direktori /home/vpopmail/domains, tapi jika saya memakai vmailmgr setiap domain akan dihandle/diurusi oleh satu user sistem yang berbeda. Saya tidak bisa membayangkan jika lupa mengetik rm -rf ~vpopmail (*kidding*) atau user vpopmail diambil alih oleh orang yang tidak berhak. Walaupun hal tersebut di vpopmail bisa diatasi dengan menggunakan switches -u dan -g untuk userid dan groupid yang berbeda untuk setiap domain, tapi perintahvaddomain di vpopmail secara default masih memakai user vpopmail untuk menghandle domain yang mau ditambah. Alasan yang lain adalah saya ingin membatasi pemakai harddisk (quota) perdomain. Jika memakai vmailmgr saya tinggal mensetup quota system untuk user yang menangani suatu domain tertentu, dan voila, satu domain tersebut sudah diquota, sekali lagi ini alasan pribadi saya, dan anda (sangat) boleh tidak setuju
Jika anda menggunakan redhat 7.3 (dengan gcc-2.96) silakan download patch untuk membetulkan kesalahan pada waktu kompilasi di http://people.cakraweb.com/~asfik/gcc-vmailmgr-fix-patch atau anda bisa juga menggunakan patch dari Ondrej Sury di http://www.sury.cz/qmail/vmailmgr-gcc-3.2.diff.gz (Refferensi: 1, 2)
Donwload vmailmgr, ekstrak, dan kompilasi (dan mengepatch, jika gcc anda bermasalah) :
[root@wedus src]# wget http://www.vmailmgr.org/current/vmailmgr-0.96.9.tar.gz
[root@wedus src]# wget http://people.cakraweb.com/~asfik/gcc-vmailmgr-fix-patch
[root@wedus src]# tar -xzvf vmailmgr-0.96.9.tar.gz
[root@wedus src]# cd vmailmgr-0.96.9
[root@wedus vmailmgr-0.96.9]# ./configure
Sekali lagi , jika anda tidak menggunakan Redhat 7.3 (gcc-2.96) abaikan command patch dibawah ini, anda bisa langsung make :
[root@wedus vmailmgr-0.96.9]# patch -p1 < ../gcc-vmailmgr-fix-patch
[root@wedus vmailmgr-0.96.9]# make
[root@wedus vmailmgr-0.96.9]# make install
Buat direktori dan file script supervise untuk menjalankan qmail-pop3d (pop server) :
[root@wedus asfik]# mkdir -p /var/qmail/supervise/qmail-pop3d
[root@wedus asfik]# vi /var/qmail/supervise/qmail-pop3d/run
Isinya :
#!/bin/sh
PATH=$PATH:/usr/local/bin:/var/qmail/bin
export PATH
MAXPOP3D=30
exec /usr/local/bin/softlimit -m 5000000 tcpserver -H -v -c “$MAXPOP3D” 0 110 qmail-popup gibas.wedus.com checkvpw qmail-pop3d Maildir/ 2>&1
Silakan anda sesuaikan variabel MAXPOP3D dan hostname gibas.wedus.comdengan konfigurasi yang sesuai dengan kondisi mail server anda.
Buat file script supervise untuk menjalankan log qmail-pop3d :
[root@wedus asfik]# mkdir -p /var/qmail/supervise/qmail-pop3d/log
[root@wedus asfik]# vi /var/qmail/supervise/qmail-pop3d/log/run
Isinya :
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t s1048576 /var/log/qmail/pop3d
Buat direktori log qmail-pop3d serta mengeset file script tersebut menjadi executable :
[root@wedus asfik]# mkdir /var/log/qmail/pop3d
[root@wedus asfik]# chown qmaill /var/log/qmail/pop3d
[root@wedus asfik]# chmod 755 /var/qmail/supervise/qmail-pop3d/run
[root@wedus asfik]# chmod 755 /var/qmail/supervise/qmail-pop3d/log/run
Akhirnya kita masukkan script supervise qmail-pop3d kedalam /service :
[root@wedus asfik]# ln -s /var/qmail/supervise/qmail-pop3d /service
Untuk memeriksa apakah servise pop3 server sudah bekerja :
[root@wedus asfik]# ps ax grep tcpserver
1057 ? S 0:00 tcpserver -H -R -v -x /etc/tcp.smtp.cdb -c 30 -u 503
1061 ? S 0:00 tcpserver -H -v -c 30 0 110 qmail-popup gibas.wedus.com
Untuk sekedar memastikan, anda bisa mencoba telnet ke localhost port 110 :
[root@wedus asfik]# telnet localhost 110
Trying 127.0.0.1…
Connected to localhost.
Escape character is ‘^]’.
+OK <5724.1035514277@gibas.wedus.com>
Download script untuk menjalankan qmail, anda bisa download di http://www.lifewithqmail.org/qmailctl-script-dt70 namun anda harus menambahkan untuk start/stop daemon pop3d nya, atau alternatif lain script yang sudah ditambah start/stop daemon pop3d di http://people.cakraweb.com/~asfik/qmailctl :
[root@wedus src]# wget http://people.cakraweb.com/~asfik/qmailctl
[root@wedus src]# mv qmailctl /var/qmail/bin/qmailctl
[root@wedus src]# chmod 755 /var/qmail/bin/qmailctl
[root@wedus src]# ln -s /var/qmail/bin/qmailctl /usr/bin
Reza Iskandar Ahmad berpendapat bahwa script qmailctl dari website Dave Sill kurang efektif, dikutip dari email yang dikirimkannya :
“qmailctl dari Dave Sill tidak efektif untuk menghentikan proses qmail. Oleh karena ini seharusnya untuk menghentikan proses qmail terlebih dahulu menghapus symlink script supervise ke /service, barulah kemudian dengan invokasi svc -dx ke direktori script supervise. Hal tersebut akan lebih efektif.” Jika anda setuju, berikut ini tambahan (yang dirubah) pada file qmailctl menurutnya :
[...]
start)
echo -n “Starting qmail : “
ln -s /var/qmail/supervise/* /service
;;
[...]
stop)
echo -n “Stopping qmail: “
rm -f /service/qmail-*
svc -dx /var/qmail/supervise/*
svc -dx /var/qmail/supervise/*/log
;;
[..]
Jika anda tidak memakai Redhat based style, anda bisa langsung ke Start-Stop qmail :
[root@wedus src]# ln -s /var/qmail/bin/qmailctl /etc/rc.d/init.d/qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc0.d/K30qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc1.d/K30qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc2.d/S80qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc3.d/S80qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc4.d/S80qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc5.d/S80qmail
[root@wedus src]# ln -s /etc/rc.d/init.d/qmail/qmail /etc/rc.d/rc6.d/K30qmail
Untuk Start-Stop qmail anda bisa lakukan perintah berikut :
[root@wedus src]# qmailctl stop
Stopping qmail…
qmail-smtpd
qmail-send
qmail-pop3d
[root@wedus src]# qmailctl start
Starting qmail
Atau dengan gaya klasik koboi Redhat :
[root@wedus src]# service qmail stop
Stopping qmail…
qmail-smtpd
qmail-send
qmail-pop3d
[root@wedus src]# service qmail start
Starting qmail
Kadang kita butuh akses ke wrapper sendmail (misalnya script cgi) atau mua yang menggunakan wrapper sendmail (mutt, pine dll), jadi kita lakukan symlink ke binari qmail untuk wrapper sendmail :
[root@wedus src]# ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail
[root@wedus src]# ln -s /var/qmail/bin/sendmail /usr/bin/sendmail
Penambahan virtual domain di vmailmgr
Disini misalnya kita membuat sebuah virtual domain kadal.edu dengan user sistem yang menghandle adalah kadal. Ingat password yang diberikan untuk user kadal akan kita gunakan nanti dalam memanage domain kadal.edu menggunakan omail-admin :
[root@wedus asfik]# adduser kadal
[root@wedus asfik]# passwd kadal
Changing password for user kadal.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
[root@wedus asfik]# echo kadal.edu >> /var/qmail/control/rcpthosts
[root@wedus asfik]# echo kadal.edu:kadal >> /var/qmail/control/virtualdomains
Jangan lupa mengirim sinyal HUP ke qmail-send agar membaca file konfigurasi yang baru :
[root@wedus asfik]# killall -HUP qmail-send
Kemudian kita ganti (su – ) ke user kadal untuk mengeset direktori dan file-file yang dibutuhkan oleh vmailmgr untuk domain kadal.edu :
[root@wedus asfik]# su – kadal
[kadal@wedus kadal]$ vsetup
vsetup: created users directory.
vsetup: wrote ‘.qmail-default’ file.
vsetup: added alias ‘mailer-daemon’
vsetup: added alias ‘postmaster’
vsetup: added alias ‘root’
Kita coba buat sebuah user name (account email) asfik@kadal.edu :
[kadal@wedus kadal]$ vadduser asfik
Enter the user’s new password:
Please type it again for verification:
vadduser: user ‘asfik’ successfully added
Kemudian kita forward email postmaster@kadal.edu, mailer-daemon@kadal.edu, root@kadal.edu ke alamat email yang valid, misalnya asfik@kadal.edu :
[kadal@wedus kadal]$ vchforwards postmaster asfik
vchforwards: User ‘postmaster’ successfully changed.
[kadal@wedus kadal]$ vchforwards mailer-daemon asfik
vchforwards: User ‘mailer-daemon’ successfully changed.
[kadal@wedus kadal]$ vchforwards root asfik
vchforwards: User ‘root’ successfully changed.
Untuk penghapusan suatu user (email account), misalnya embuh@kadal.edu :
[kadal@wedus kadal]$ vdeluser embuh
vdeluser: user ‘embuh’ successfully deleted.
Kemudian kita mencoba mengetest mengirim email dari asfik@wedus.com ke asfik@kadal.edu , dari perintah tail -f /var/log/qmail/current kita dapatkan log seperti berikut :
[root@wedus asfik]# tail -f /var/log/qmail/current
@400000003db6657501bc540c new msg 224662
@400000003db6657501bc6b7c info msg 224662: bytes 906 from qp 995 uid 503
@400000003db6657501e995fc starting delivery 1: msg 224662 to local kadal-asfik@kadal.edu
@400000003db6657501eb3fc4 status: local 1/10 remote 0/20
@400000003db6657504fac1e4 delivery 1: success: did_0+0+1/
@400000003db6657504fad954 status: local 0/10 remote 0/20
@400000003db6657504fd8cbc end msg 224662
Jika anda mengubah hasil format log dari unix timestamps ke format yang lebih mudah dibaca oleh manusia, anda bisa piping dengan menggunakan tai64nlocal :
[root@wedus asfik]# tail -f /var/log/qmail/current tai64nlocal
2002-10-23 16:01:31.029119500 new msg 224662
2002-10-23 16:01:31.029125500 info msg 224662: bytes 906 from qp 995 uid 503
2002-10-23 16:01:31.032085500 starting delivery 1: msg 224662 to local kadal-asfik@kadal.edu
2002-10-23 16:01:31.032194500 status: local 1/10 remote 0/20
2002-10-23 16:01:31.083542500 delivery 1: success: did_0+0+1/
2002-10-23 16:01:31.083548500 status: local 0/10 remote 0/20
2002-10-23 16:01:31.083725500 end msg 224662
Lalu kita periksa apakah email tersebut sudah masuk ke dalam mailbox asfik@kadal.edu, anda bisa menggunakan POP3 client, misalnya Eudora, anda harus menggunakan format user@domain misalnya asfik@kadal.edu sebagai accoutname atau username untuk authentikasi ke server POP tersebut, atau anda juga bisa melalui old-fashioned-way, telnet port 110 di localhost :
[root@wedus asfik]# telnet localhost 110
Trying 127.0.0.1…
Connected to localhost.
Escape character is ‘^]’.
+OK <5897.1035517402@gibas.wedus.com>
user asfik@kadal.edu
+OK
pass 123
+OK
list
+OK
1 988
.
quit
+OK
Connection closed by foreign host.
Disitu kita lihat email sudah masuk dengan sukses. Untuk melakukan penambahan virtual domain yang lain silakan mengulangi langkah-langkah diatas. Untuk perintah-perintah yang lain didalam vmailmgr anda bisa mencoba : vaddalias vadduser vaddusers vchattr vchforwards vdeluser vpasswd vpasswds vpopbull vrehash vsetup .
3. Instalasi Omail-Admin
Omail admin dipakai untuk memanage account user pada suatu domain dengan menggunakan web. Membutuhkan suatu webserver, misalnya apache yang sudah dikonfigurasi dengan modul php. Omail admin membutuhkan paket ucspi-unix yang digunakan untuk authentikasi dan paket qmail-autoresponder. Saya mencoba menggunakan source tarball untuk menginstal ucspi-unix, namun pada waktu make terjadi error, maka saya menggunakan ucspi-unix versi rpm.
Download paket ucspi-unix versi rpm :
[root@wedus src]# wget http://untroubled.org/ucspi-unix/rh7/ucspi-unix-0.36-1.i386.rpm
[root@wedus src]# rpm -ivh ucspi-unix-0.36-1.i386.rpm

[root@wedus asfik]# vi /var/qmail/supervise/vmailmgrd/run
Isinya :
#!/bin/sh
exec /usr/local/bin/softlimit -m 9000000 /usr/bin/unixserver -v — /tmp/.vmailmgrd /usr/local/sbin/vmailmgrd -V 2>&1
Buat direktori supervise untuk log vmailmgrd dan mengubah setting file script menjadi executable :
[root@wedus asfik]# mkdir -p /var/log/qmail/vmailmgrd
[root@wedus asfik]# chown qmaill /var/log/qmail/vmailmgrd
[root@wedus asfik]# chmod 755 /var/qmail/supervise/vmailmgrd/log/run /var/qmail/supervise/vmailmgrd/run
Akhirnya kita masukkan servis vmailmgrd kedalam /service :
[root@wedus asfik]# ln -s /var/qmail/supervise/vmailmgrd/ /service/
Donwload paket omail-admin dan qmail-autoresponder, dilanjutkan kompilasi dan instalasi :
[root@wedus src]# wget http://unc.dl.sourceforge.net/sourceforge/omail/omail-admin-0.99-beta.tar.gz
[root@wedus src]# wget http://untroubled.org/qmail-autoresponder/qmail-autoresponder-0.95.tar.gz
[root@wedus src]# tar -xzvf qmail-autoresponder-0.95.tar.gz
[root@wedus src]# cd qmail-autoresponder-0.95
[root@wedus qmail-autoresponder-0.95]# make
[root@wedus qmail-autoresponder-0.95]# cp qmail-autoresponder /usr/local/bin/
[root@wedus qmail-autoresponder-0.95]# cd ..
[root@wedus src]# tar -xzvf omail-admin-0.99-beta.tar.gz
Disini anda harus menentukan URL dimana omail-admin bisa diakses. Anda bisa melihat file konfigurasi apache anda (httpd.conf)dan mencari directive DocumentRoot. Kalau anda menggunakan apache dari paket RPM Redhat, biasanya default DocumentRoot terdapat pada direktori /var/www/html. Disini saya contohkan domain saya adalah wedus.comdengan DocumentRoot di /usr/local/httpd/htdocs :
[root@wedus src]# mv omail-admin-0.99-beta /usr/local/httpd/htdocs/admin
Edit file config.php dan ganti variabel $sysadmin_maildengan email yang bertanggung jawab terhadap omail-admin, misalnya $sysadmin_mail = “asfik@wedus.com”; :
[root@wedus src]# vi /usr/local/httpd/htdocs/admin/config.php
Dan jika anda menginginkan default dari bahasanya adalah indonesia, ubah variabel $default_language :
$default_language = “id”;
Kemudian anda bisa mencoba login untuk memanage domain kadal.edu dengan menggunakan username kadal dan password yang telah kita berikan diatas, melalui url http://www.wedus.com/admin. Jika ada pesan kesalahan login tidak diterima atau password salah, silakan anda periksa file php.ini, pastikan register_global=On. Jika anda berhasil login, anda bisa melihat log dari authentikasi user kadal pada file /var/log/qmail/vmailmgrd/current dengan perintah sebagai berikut :
[root@wedus src]# tail -f /var/log/qmail/vmailmgrd/current
@400000003db76f1112f4bad4 [4242] Accepted connection
@400000003db76f1112f6d9cc [4242] Request: listdomain kadal.edu
@400000003db76f11131fd5fc [4242] Completed: OK:

@400000003db76f11137dad6c [4243] Request: listdomain kadal.edu @400000003db76f1113a6922c [4243] Completed: OK:
@400000003db76f1113ea1b3c [4244] Accepted connection
@400000003db76f1113eef954 [4244] Request: autoresponse kadal-asfik
status
@400000003db76f111420a044 [4244] Completed: OK: nonexistant
@400000003db76f11187187bc [4245] Accepted connection
@400000003db76f111873ba3c [4245] Request: listdomain kadal.edu
Mengeset vmailmgr supaya menjalankan qmail-autoresponder :
[root@wedus src]# mkdir /etc/vmailmgr
[root@wedus src]# vi /etc/vmailmgr/vdeliver-postdeliver
Isinya :
#!/bin/sh
if test -s $MAILDIR/autoresponse/message.txt
then
qmail-autoresponder message.txt $MAILDIR/autoresponse
fi
Set menjadi file yang bisa dieksekusi :
[root@wedus src]# chmod 755 /etc/vmailmgr/vdeliver-postdeliver
Jika anda tidak membutuhkan fasilitas webmail akses untuk user anda silakan meloncat ke “Lain-lain”, membaca tulisan dibawah ini hanya akan menghabiskan waktu anda, lebih baik digunakan untuk tidur atau nonton tv .
4. Instalasi Courier Imap
Courier Imap, sesuai dengan namanya adalah sebuah IMAP server, yaitu sebuah IMAP server yang mendukung format penyimpanan email dengan menggunakan format Maildir. Dalam hal ini kita menggunakan Courier Imap untuk backend dari webmail squirrelmail.
Donwload courier-imap, ekstrak sourcenya, dan kita kompilasi :
[root@wedus src]# wget http://unc.dl.sourceforge.net/sourceforge/courier/courier-imap-1.5.3.tar.gz
[root@wedus src]# tar -xzvf courier-imap-1.5.3.tar.gz
[root@wedus src]# cd courier-imap-1.5.3
[root@wedus courier-imap-1.5.3]# ./configure –enable-workarounds-for-imap-client-bugs –disable-root-check –without-authcram –without-authcustom –without-authldap –without-authpam –without-authpgsql –without-authuserdb –without-authdaemon –without-authmysql –without-authvchkpw –without-authshadow
[root@wedus courier-imap-1.5.3]# make
[root@wedus courier-imap-1.5.3]# make install
Kita tidak membutuhkan module authentikasi yang lain (jika ada), selain authvmailmgr, jadi module dari courier-imap ya dihapus saja :
[root@wedus courier-imap-1.5.3]# rm -rf /usr/lib/courier-imap/libexec/authlib/*
Salin modul authvmailmgr dari source vmailmgr yang telah kita kompilasi diatas ke direktori modul authentikasi untuk imap servernya :
[root@wedus courier-imap-1.5.3]# cp ../vmailmgr-0.96.9/authenticate/authvmailmgr /usr/lib/courier-imap/libexec/authlib/
Salin file konfigurasi standar dari courier-imap :
[root@wedus courier-imap-1.5.3]# cp /usr/lib/courier-imap/etc/imapd.dist /usr/lib/courier-imap/etc/imapd
[root@wedus courier-imap-1.5.3]# cp /usr/lib/courier-imap/etc/imapd-ssl.dist /usr/lib/courier-imap/etc/imapd-ssl
Edit file /usr/lib/courier-imap/etc/imapd , karena courier imap ini hanya digunakan untuk webmail ganti pada baris ADDRESS=0 menjadi ADDRESS=127.0.0.1 . Jika webmail anda adalah webmail yang sibuk, anda bisa menaikkan variabel MAXDAEMONS dan MAXPERIP, yang terpenting adalah ganti pada AUTHMODULES=”authdaemon” menjadi AUTHMODULES=”authvmailmgr”:
[root@wedus courier-imap-1.5.3]# vi /usr/lib/courier-imap/etc/imapd
Start daemon courier-imap :
[root@wedus courier-imap-1.5.3]# /usr/lib/courier-imap/libexec/imapd.rc start
Anda bisa memeriksa apakah servise courier-imap anda sudah berjalan semestinya, kita gunakan perintah ps :
[root@wedus courier-imap-1.5.3]# ps ax grep imap
2049 ? S 0:00 /usr/lib/courier-imap/libexec/couriertcpd -address=12
2052 ? S 0:00 /usr/lib/courier-imap/libexec/courierlogger imapd
Agar setiap reboot daemon courier-imap dijalankan secara otomatis :
[root@wedus courier-imap-1.5.3]# echo “/usr/lib/courier-imap/libexec/imapd.rc start” >> /etc/rc.local
5. Instalasi Squirrelmail
Menurut file INSTALL dari distribusi Squirrelmail, software ini membutuhkan php4 yang minimal dikompilasi dengan opsi –enable-track-vars –enable-force-cgi-redirect –with-gettext serta membutuhkan register_global=On dan file_uploads = On di php.ini (jika php anda menggunakan default RPM Redhat file php.ini terletak didirektori /etc).
Download dan ekstrak paket squirrelmail :
[root@wedus src]# wget http://unc.dl.sourceforge.net/sourceforge/squirrelmail/squirrelmail-1.2.8.tar.gz
[root@wedus src]# tar -xzvf squirrelmail-1.2.8.tar.gz
Tentukan letak direktori squirrelmail, misalnya disini saya letakkan didirektori /usr/local/httpd/htdocs/sqmail sehingga akan bisa diakses melalui http://www.wedus.com/sqmail
[root@wedus src]# mv squirrelmail-1.2.8 /usr/local/httpd/htdocs/sqmail
Tentukan user dan group yang menjalankan proses apache :
[root@wedus src]# egrep ‘^(UserGroup)’ /usr/local/httpd/conf/httpd.conf
User www
Group www
Dari perintah diatas kita peroleh user www dan group www, kemudian ganti kepemilikan direktori /usr/local/httpd/htdocs/sqmail/data menjadi user www dan group www :
[root@wedus src]# chown -R www.www /usr/local/httpd/htdocs/sqmail/data/
Salin file konfigurasi standar ke file konfigurasi squirrelmail :
[root@wedus src]# cp /usr/local/httpd/htdocs/sqmail/config/config_default.php /usr/local/httpd/htdocs/sqmail/config/config.php
Edit file tersebut dari $imap_server_type = ‘cyrus’; menjadi$imap_server_type = ‘courier’; :
[root@wedus src]# vi /usr/local/httpd/htdocs/sqmail/config/config.php
Atau jika anda mengalami kesulitan anda bisa menggunakan script perl yang disertakan oleh squirrelmail, pada direktori config :
[root@wedus src]# cd /usr/local/httpd/htdocs/sqmail/config
[root@wedus config]# ./conf.pl
Kemudian silakan dicoba dengan browser anda, misalnya http://www.wedus.com/sqmail, kemudian masukkan user yang telah anda buat misalnya asfik@kadal.edu kemudian anda bisa mengganti Personal Information atau Folder Preferences dari menu Options.
6. Lain-lain
Didalam penggunaannya, terkadang qmail menemui suatu masalah, misalnya queue macet atau menumpuk, atau mailbox anda dispam dan kemudian bounce ke alamat yang tidak ketahuan jluntrung dan sangkan parannya ataupun tiba-tiba struktur direktori queue anda rusak. Atau anda punya gagasan untuk membatasi total pemakain harddisk untuk suatu domain.
6.1 qmHandle
qmHandle digunakan untuk melihat direktori queue ataupun menghapus dan melihat suatu email di direktori queue. Program ini membutuhkan perl, jadi silakan diperiksa distro linux kesayangan anda, apakah sudah terinstall perl atau belum.
[root@wedus src]# wget http://www.io.com/~mick/soft/qmHandle-0.5.1.tar.gz
[root@wedus src]# tar -xzvf qmHandle-0.5.1.tar.gz
Edit file qmHandle :
[root@wedus src]# vi qmHandle
Hapus atau beri tanda “#” pada baris ini :
$qmcmd = “csh -cf ‘/var/qmail/rc &’”;
Unmark/uncommnet (hilangkan tanda “#”) pada baris ini :
$qmcmd = ‘/etc/init.d/qmail start’;
Atau jika anda tidak menggunakan init untuk memulai qmail :
$qmcmd = ‘/usr/bin/qmailctl start’;
Pindahkan file binari nya ke direktori /usr/sbin atau direktori dimana anda ingat file tsb dan masuk lingkungan $PATH anda :
[root@wedus src]# mv qmHandle /usr/sbin/
Jika tidak ada email yang menyangkut di direktori queue, hasil perintah qmHandle -l -c adalah :
[root@wedus src]# qmHandle -l -c
Messages in local queue: 0
Messages in remote queue: 0
Misalkan ada sebuah email yang bounce dan numpuk direktori queue :
[root@wedus src]# qmHandle -l -c
15643 (3, R)
Return-path:
From: MAILER-DAEMON@gibas.wedus.com
To: lVKXwgvIgtQ3BL6d2TeG27oGW_yy@reply.yahoo.com
Subject: failure notice
Date: 30 Oct 2002 01:26:58 -0000
Size: 14634 bytes
Dan anda ingin menghapusnya (nomor 15643 didapat dari hasil diatas):
[root@wedus src]# qmHandle -d15643
Terminating qmail (pid 491)… this might take a while if qmail is working.
Restarting qmail… Starting qmail done (hopefully).
Untuk menghapus beberapa nomor sekaligus (misalnya nomor 1,2,3) anda bisa menggunakan qmHandle -d1 -d2 -d3 untuk menghapusnya, untuk penggunaan lebih lanjut qmHandle -h
6.2 queue-fix
Jika direktori queue anda tiba-tiba membengkak dan banyak antrian di queue, mungkin mailbox anda ada yang terkena spam atau virus atau diserang (let’s say dibomb lah). Anda bisa melihat salah satu message email yang terkena spam/virus/bomb tersebut dengan qmHandle. Tapi jika jumlah message banyak menghapus dengan qmHandle adalah pekerjaan yang melelahkan , solusinya mungkin bisa dengan menghapus direktori queue yang lama dan mengganti dengan direktori queue yang baru.
[root@wedus src]# wget http://www.netmeridian.com/e-huss/queue-fix.tar.gz
[root@wedus src]# tar -xzvf queue-fix.tar.gz
[root@wedus src]# cd queue-fix-1.4/
[root@wedus queue-fix-1.4]# make
Pindahkan file binari nya ke direktori /usr/sbin atau direktori dimana anda ingat file tsb dan masuk lingkungan $PATH anda :
[root@wedus queue-fix-1.4]# cp queue-fix /usr/sbin/
Jika anda ingin membetulkan struktur direktori queue qmail saja :
[root@wedus queue-fix-1.4]# qmailctl stop
[root@wedus queue-fix-1.4]# queue-fix -i /var/qmail/queue/
[root@wedus queue-fix-1.4]# qmailctl start
Jika anda ingin mengganti (menghapus yang lama dan membuat yang baru) struktur direktori queue qmail, perintah mv ditujukan untuk membackup direktori queue jika suatu saat nanti akan dilakukan investigasi dari pihak berwajib (anda?):
[root@wedus queue-fix-1.4]# qmailctl stop
[root@wedus queue-fix-1.4]# mv /var/qmail/queue/ /var/qmail/old-queue
[root@wedus queue-fix-1.4]# mkdir /var/qmail/queue/
[root@wedus queue-fix-1.4]# queue-fix -i /var/qmail/queue/
[root@wedus queue-fix-1.4]# qmailctl start
6.3 Quota Perdomain
Tujuannya adalah membatasi pemakaian harddisk untuk suatu domain. Prinsipnya setiap domain yang akan kita quota, kita cari dulu user system yang menghandle domain tersebut kemudian kita quota. Bagaimana cara mengatur quota pada linux dengan baik dan benar, silakan kunjungi http://www.tldp.org/HOWTO/mini/Quota.html.Sebelumnya anda juga harus menentukan home direktori dari user-user yang akan menghandle virtual domain anda, akan lebih baik jika home direktori tersebut diletakkan pada partisi yang terpisah (misalnya /home) agar mudah untuk melakukan quota.
Jika direktori /home anda akan diquota maka pada file /etc/fstab anda ubah dari :
LABEL=/home /home ext3 defaults 1 2
Menjadi :
LABEL=/home /home ext3 defaults,usrquota 1 2
Buat file kosong pada partisi /home ganti modenya menjadi 700 :
[root@wedus asfik]# touch /home/aquota.user
[root@wedus asfik]# chmod 700 /home/aquota.user
Reboot linux anda, pastikan setiap reboot akan menjalankan quotaon, default pada Redhat sudah dimasukkan dalam file /etc/rc.d/rc.sysinit . Lakukan quotacheck sebelum melakukan penambahan quota :
[root@wedus asfik]# quotacheck -avugfm
Test apakah quota sudah terpasang dengan semestinya :
[root@wedus asfik]# quota -uv root
Disk quotas for user root (uid 0):
Filesystem blocks quota limit grace files quota limit grace
/dev/hda8 135052 0 0 3545 0 0
Jika belum terpasang maka hasil keluaran perintah diatas adalah :
[root@wedus asfik]# quota -uv root
Disk quotas for user root (uid 0): none
Sekarang kita coba untuk memberi quota pada domain yang kita buat tersebut diatas, misalnya kadal.edu :
[root@wedus asfik]# grep ^kadal.edu /var/qmail/control/virtualdomains
kadal.edu:kadal
Dari keluaran perintah diatas kita dapatkan bahwa domain kadal.edu ditangane oleh user kadal , kita set quota untuk domain tersebut ke 10 MB misalnya :
[root@wedus asfik]# setquota -u kadal 10240 10240 0 0 /home
[root@wedus asfik]# quota -uv kadal
Disk quotas for user kadal (uid 188):
Filesystem blocks quota limit grace files quota limit grace
/dev/hda7 496 10000 10000 none 212 0 0
Jika suatu saat user kadal telah melebihi quota (ditunjukkan dengan tanda * pada hasil keluaran perintah quota) yang kita berikan maka semua email yang dikirm ke domain tersebut akan dibounce ke sendernya (dikirim balik ke pengirimnya) :
[root@wedus asfik]# quota -uv kadal
Disk quotas for user kadal (uid 188):
Filesystem blocks quota limit grace files quota limit grace
/dev/hda7 11496* 10000 10000 none 212 0 0
Hasil dari perintah tail -f /var/log/qmail/current yang menunjukkan email tersebut dibounce :
[root@wedus asfik]# tail -f /var/log/qmail/current
@400000003dbf7bb835dc0084 info msg 48056: bytes 890 from qp 21917 uid 908

Server apache dengan httpd-2.2.2.tar.gz (suse)

Download Source Get the source from http://httpd.apache.org/download.cgi . At the time of writing this tutorial the best available version was 2.2.2 ( httpd-2.2.2.tar.gz ). This tutorial is known to work with all 2.x.x Apache versions.
Unpack, Configure, Compile Go to the directory with the downloaded file and enter:
# tar -xzf httpd-2.2.2.tar.gz # cd httpd-2.2.2 # ./configure –prefix=/usr/local/apache2 –enable-so The configure options deserve a little bit more of detail here. The most important –prefix option specifies the location where Apache is to be installed. Another commonly used option –enable-so turns on the DSO support, i.e. available modules compiled as shared objects can be loaded or unloaded at runtime. Very handy.
To compile some modules statically (they are always loaded, faster execution times), use –enable-module option. To compile a module as a shared object, use –enable-module=shared option.
SSL SupportTo support secure connections, you need to specify –enable-ssl option when you run ./configure. In addition to that, you will also have to configure your httpd.conf file later.
Note: Make sure that openssl is installed on your system before you run ./configure with –enable-ssl. If not, download the latest version from http://www.openssl.org/source/ , unpack, configure, make, make install. You will also need to generate server certificates.
Configuration ExampleFor example, to compile the mod_rewrite module statically and mod_auth_digest as a DSO, and to enable secure connections, enter:
# ./configure –prefix=/usr/local/apache2 –enable-so –enable-rewrite –enable-auth-digest=shared –enable-ssl For all available configuration options and their default values check the Apache documentation or type ./configure –help.
Tip: If you are upgrading from older Apache version, you may want to copy config.nice from the old Apache installation directory (if available) to where you unpacked the new Apache tarball file. Run ./config.nice instead of ./configure. This way all the previous configure options will be applied to the new installation effortlessly.
Once you configured everything as you like, compile and install the software:
# make # make install Edit httpd.confBefore you start Apache server, edit the httpd.conf file according to your needs (the file is generously commented).
# vi /usr/local/apache2/conf/httpd.conf I suggest the following changes (some of them may have already been set automatically) on the appropriate places inside httpd.conf (ignore “…”):
ServerRoot “/usr/local/apache2″ … User apache2 Group www … DocumentRoot “/foo/path_to_your_www_documents_root” … Options FollowSymLinks AllowOverride None … DirectoryIndex index.php index.html index.htm index.html.var
“apache2″ and “www” are the user and user group I have previously created (see Prerequisites)
Apart from these, later you will probably want to specify detailed options for specific directories, load some DSO modules, setup virtual servers etc.
SSL Support If you wish to enable SSL for secure connections (assuming that you have configured Apache with –enable-ssl option – see above), add the following in the appropriate sections inside httpd.conf (ignore “…”; replace “laffers.net” with your own):
Listen 80Listen 443… ServerName laffers.net:443 SSLEngine on ErrorLog /usr/local/apache2/logs/error_log_laffers.net TransferLog /usr/local/apache2/logs/access_log_laffers.net SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SetEnvIf User-Agent “.*MSIE.*” \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 After you installed PHP (next part of this tutorial), few additional changes need to be done to httpd.conf (but they are usually made automatically during PHP installation).
Setup Access PrivilegesDon’t forget to setup Apache access privileges to your www directories:
# chown -R apache2 /foo/path_to_your_www_documents_root # chgrp -R www /foo/path_to_your_www_documents_root # chmod -R 750 /foo/path_to_your_www_documents_root “apache2″ and “www” are the user and user group I have previously created (see Prerequisites)
Start and Stop Apache ServerAfter everything is set up, start Apache:
# /usr/local/apache2/bin/apachectl start
Similarly, if you wish to stop Apache, type:
# /usr/local/apache2/bin/apachectl stop
Automatic Startup It’s a good idea to let your Apache server start automatically after each system reboot. To setup Apache automatic startup, do:
# cp /usr/local/apache2/bin/apachectl /etc/init.d # chmod 755 /etc/init.d/apachectl # chkconfig –add apachectl # chkconfig –level 35 apachectl on

This application may or may not work on your platform.

It was written for Linux and requires strncasecmp() and fcntl() which may not be
supported by your OS.

Under certain conditions this application will crash.

example, If client load exceeds FD_SETSIZE minus any other file descriptors you use.

This is only a brief out line at what you require to build a basic chat server.

Step 1.

You will be required to have a method of storing details about each connection and user information.

To make things easier we will use double linked lists from my previous Tutorial.
Please see this tutorial on howto write functions to insert/delete/list/clear data in the below linked list, or alternatively download chatserver-tutorial-v0.1.tar.gz.
struct UsersConnections;
typedef struct UsersConnections UsersConnections;
typedef UsersConnections *UsersConnectionsPTR;

struct Users;
typedef struct Users Users;
typedef Users *UsersPTR;

// List of users connections to server
struct UsersConnections {
int sockfd;
char IP[16];
UsersPTR User;
struct UsersConnections *Prev;
struct UsersConnections *Next;
};
UsersConnectionsPTR UsersConnectionsStart;

// List of users information
struct Users {
UsersConnectionsPTR Connection;
int status;
char Nick[36];
struct Users *Prev;
struct Users *Next;
};
UsersPTR UsersStart;

Step 2.

As a server daemon there are a few things we need to do:

a) Fork the process to the background
b) Bind the daemon to a port and listen for new connections
c) Check for new connections
d) Accept new connetions
e) Check for incomming data on each connection, read if any and process
Fork the process to the background
int main() {
pid_t pid;

if(!(pid = fork())) {
pid=getpid();

/* code goes here */
}
}

Bind the daemon to a port and listen for new connections
int main() {
int clientfd;
pid_t pid;

UsersStart = NULL;
UsersConnectionsStart = NULL;

// Listen for connections on port 9000
clientfd = ListenConnection(9000);

if(!(pid = fork())) {
pid=getpid();

/* code goes here */
}
}

int ListenConnection(int port) {

int sockfd;
struct sockaddr_in myaddr;

myaddr.sin_family = AF_INET;
myaddr.sin_addr.s_addr = INADDR_ANY;
myaddr.sin_port = htons(port);

memset(myaddr.sin_zero, 0, sizeof(myaddr.sin_zero));

if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
perror(“socket”);
exit(1);
}

if (bind(sockfd, (struct sockaddr *)&myaddr, sizeof(struct sockaddr)) == -1) {
perror(“bind”);
exit(1);
}

// This will listen to the port but we need another function to check this
if (listen(sockfd, 100) == -1) {
perror(“listen”);
exit(1);
}
return sockfd;
}

Check and accept new connections
int running;

int main() {
int clientfd;
pid_t pid;

UsersStart = NULL;
UsersConnectionsStart = NULL;
running = 1;

// Listen for connections on port 9000

if(!(pid = fork())) {

// loop while running = 1
while(running) {

// Check for new client connections
if (CheckSocketRead(clientfd) > 0) {
// Accept the connection and add user to client list

}

// this is a temp solution to save cpu resources
usleep(200);
}
}
}

int CheckSocketRead(int sockfd) {
int rc;
struct timeval tv;
fd_set read_fd;

tv.tv_sec=0;
tv.tv_usec=1;

FD_ZERO(&read_fd);
FD_SET(sockfd, &read_fd);

rc = select(sockfd+1, &read_fd, NULL, NULL, &tv);
FD_ZERO(&read_fd);
return rc;
}

int AcceptClient(int sockfd) {
int newfd, sinsize;
struct sockaddr_in clientaddr;
UsersPTR From;
UsersConnectionsPTR Connection;

sinsize = sizeof(struct sockaddr_in);
newfd = accept(sockfd, (struct sockaddr *)&clientaddr, &sinsize);
if (newfd == -1) {
// you don’t realy want to exit here as it’s only 1 client that can’t be accepted
// however you will be required to investigate why accept returned -1
perror(“accept”);
exit(1);
} else if (newfd) {
printf(“New CLIENT connection from IP %s on socket %d\n”, \
inet_ntoa(clientaddr.sin_addr), newfd);

// Enable non-blocking socket for select()
fcntl(newfd, F_SETFL, O_NONBLOCK);

// Add user to connection list (This function is not in the example, please see
// http://www.devforge.net/downloads/chatserver-tutorial-v0.1.tar.gz
Connection = UsersConnectionsInsert(&UsersConnectionsStart, newfd, \
inet_ntoa(clientaddr.sin_addr));

// Add user to client list (This function is not in the example, please see
// http://www.devforge.net/downloads/chatserver-tutorial-v0.1.tar.gz
Connection->User = UsersInsert(&UsersStart, &Connection, “”);
}
}

Check for incomming data on each connection, read and process

UsersConnectionsDelete(&Connection);
}

Step 3.

Now that we have a working server we need to process the data and send data back to the client.

As this is a chat server the client requires a nickname, so we will have to add functionality to Process() that enables the client to set a nickname and do other things like message other users

We do not want the client to be able to message any one untill they have chosen a nickname, and we also don’t want the client to be able to chose a nickname that is already in use.

The below Process() does all the above (Please note that function lengthafterchar() is not in this example, please see http://www.devforge.net/downloads/chatserver-tutorial-v0.1.tar.gz
Process() functionality
int Process(UsersConnectionsPTR *sConnection, char *sData) {
int i;
char action[36], buffer[1024], temp[36];
UsersConnectionsPTR Connection;
UsersPTR From, To, currentPtr;

*buffer=”;

Connection = *sConnection;
From = (*sConnection)->User;

if (lengthafterchar(&sData[0], ‘ ‘)) {
snprintf(action,lengthafterchar(&sData[0], ‘ ‘),&sData[0]);
i = lengthafterchar(&sData[0], ‘ ‘);
} else {
strcpy(action,&sData[0]);
}

if (From->status) {
if (!lengthafterchar(&sData[0], ‘ ‘)) {
SendMSG(Connection->sockfd, “Unknown command\n”);

// Global messages to all authorized users
} else if (strcasecmp(action,”GLOBAL”)==0) {
if (!lengthafterchar(&sData[0], ‘ ‘)) {
SendMSG(Connection->sockfd, “Incorrect syntax for command GLOBAL: GLOBAL MESSAGE\n”);
} else {
sprintf(buffer,”GLOBAL %s %s\n”,From->Nick, &sData[i]);
printf(“<%s> GLOBAL %s\n”,From->Nick, &sData[i]);
SendALL(&UsersConnectionsStart, &Connection, buffer);
}

// Private messages to other users
} else if (strcasecmp(action,”MSG”)==0) {
if (!lengthafterchar(&sData[0], ‘ ‘)) {
SendMSG(Connection->sockfd, “Incorrect syntax for command MSG: MSG NICK MESSAGE\n”);
} else {
snprintf(temp,lengthafterchar(&sData[i], ‘ ‘),&sData[i]);
i = i + lengthafterchar(&sData[i], ‘ ‘);
To = GetUser(&UsersStart, temp);
if (To != NULL) {
sprintf(buffer,”MSG %s %s\n”,From->Nick, &sData[i]);
printf(“<%s> MSG %s %s\n”,From->Nick, To->Nick, &sData[i]);
SendMSG(To->Connection->sockfd, buffer);
} else {
sprintf(buffer,”No such nick %s\n”,temp);
SendMSG(Connection->sockfd, buffer);
}
}
} else {
SendMSG(Connection->sockfd, “Unknown command\n”);
}
} else if (strcasecmp(action,”NICK”)==0) {
if (GetUser(&UsersStart, &sData[i]) != NULL) {
SendMSG(Connection->sockfd, “Nickname is already in use, please try another.\n”);
} else {
strcpy(From->Nick, &sData[i]);
From->status = 1;
sprintf(buffer,”Welcome %s\n”,From->Nick);
SendMSG(Connection->sockfd, buffer);

sprintf(buffer,”CONNECTED %s\n”,&sData[i]);
printf(“%s”,buffer);
SendALL(&UsersConnectionsStart, &Connection, buffer);
}
} else {
SendMSG(Connection->sockfd, “You must select a nick by typing: NICK yournickname\n”);
}
}

int SendALL(UsersConnectionsPTR *sConnection, UsersConnectionsPTR *sFrom, char *sMsg) {
UsersConnectionsPTR Connection, nextPtr, currentPtr;
UsersPTR From;

currentPtr = *sConnection;
From = (*sFrom)->User;

while (currentPtr != NULL) {
nextPtr = currentPtr->Next;
if (strcasecmp(currentPtr->User->Nick,From->Nick)!=0 && currentPtr->User->status > 0) {
SendMSG(currentPtr->sockfd, sMsg);
}
currentPtr = nextPtr;
}
}

int SendMSG(int sockfd, char *msg) {
return send(sockfd, msg, strlen(msg), 0);
}

Step 4.

Time to test, compiled and started server on port 9000

I connected 2 clients to the server by telnet to localhost on port 9000
Server output
admin@notebook:~/Projects/Tutorials/chatserver$ make
gcc -O2 -g -o src/main.o -c src/main.c -Iinclude
gcc -O2 -g -o src/socket.o -c src/socket.c -Iinclude
gcc -O2 -g -o src/lists.o -c src/lists.c -Iinclude
gcc -O2 -g -o src/string.o -c src/string.c -Iinclude
gcc -O2 -g -o chatserver src/main.o src/socket.o src/lists.o src/string.o -Iinclude
Done!

Step 5.

Improving the above code.

The problem with this chat client is under extreme loads of incomming/outgoing connections it will segfault due to signals not being processed, especially when trying to send large amounts of data to users that have disconnected and have yet to be processed as quit

To solve these issues you can add 2 things to help avoid such issues,
Signal handling, ignore sigpipe
void handle_signal(int signum);

int running;

int main() {
int clientfd;
pid_t pid;

UsersStart = NULL;
UsersConnectionsStart = NULL;
running = 1;

signal (SIGSEGV, handle_signal);
signal (SIGINT, handle_signal);
signal (SIGUSR1, handle_signal);
signal (SIGUSR2, handle_signal);
signal (SIGPIPE, SIG_IGN);

// Listen for connections on port 9000
clientfd = ListenConnection(9000);

if(!(pid = fork())) {
pid=getpid();

// loop while running = 1
while(running) {

// Check for new client connections
if (CheckSocketRead(clientfd) > 0) {
// Accept the connection and add user to client list
AcceptClient(clientfd);
}

// Check for any incomming data from clients
CheckClientData();

// this is a temp solution to save cpu resources
usleep(200);
}
}
}

void handle_signal(int signum) {
// This will require you to research more on signal handling
printf(“SIGNAL %d\n”, signum);
if (signum == 11 || signum == 2) exit(0);
}

Using CheckSocketWrite(Connection->sockfd) to see if we can write to that socket
int CheckSocketWrite(int sockfd) {
int rc;
struct timeval tv;
fd_set write_fd;

tv.tv_sec=0;
tv.tv_usec=1;

FD_ZERO(&write_fd);
FD_SET(sockfd, &write_fd);

rc = select(sockfd+1, NULL, &write_fd, NULL, &tv);
FD_ZERO(&write_fd);
return rc;
}
