Menggunakan YUM dibelakang PROXY di CentOS

Walau trik ini sudah banyak yang tahu, namun saya hanya ingin meramaikan blog mengenai tutoriak/trik mengenai Linux. Bagi yang belum tahu atau sedang asyik-asyiknya bermain Linux berikut trik sederhananya yah.. :)

Konfigurasi 1 (cara pertama) 
Memasangkan proxy di dalam file /etc/yum.conf:

proxy=http://192.168.1.2:1
proxy_username=admin@rijalhanif.net
proxy_password=123password

Konfigurasi 2 (cara kedua)
Memasangkan proxy di variable environment

http_proxy="http://jaya@rijal.com:123456@192.168.1.187:8080"
export http_proxy

Ganti nama ethX di CentOS/RHEL

Adakalanya nama ethX anda berubah menjadi ethX dengan urutan yang tidak sesuai atau tidak bermula dari awal.

1. Buka file: /etc/udev/rules.d/70-persistent-net.rules

2. Ganti bagian eth, menjadi eth0 atau disesuaikan dengan keinginan Anda.

SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”00:50:56:b2:23:e0″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″

3. Buka file: /etc/sysconfig/network-scripts/ifcfg-eth0
Atau jika tidak ada, rename dari konfigurasi sebelumnya, mungkin dari nama ifcfg-eth3

*Thanks, Semoga bermanfaat.

Auto Login User on Ubuntu (Tested 10.04)

Buat file di: /etc/gdm/custom.conf

Isikan dengan:

[daemon]
TimedLoginEnable=true
AutomaticLoginEnable=true
TimedLogin=monitor
AutomaticLogin=monitor
TimedLoginDelay=10
DefaultSession=gnome

Lalu.. restart Ubuntu anda:
# shutdown -r now

Install SquidGuard Manager 1.12 on Red Hat X86_64

Persiapan:
1. Download file http://www.sourceforge.net/projects/squidguardmgr/
2. Kopi filenya ke direktori /usr/local/src/

Compile:
[root@tester src]# tar xfvz squidguardmgr-1.12.tar.gz
[root@tester src]# cd squidguardmgr-1.12
[root@tester squidguardmgr-1.12]# perl -v

This is perl, v5.8.8 built for x86_64-linux-thread-multi

[root@tester squidguardmgr-1.12]# perl Makefile.PL
Path to squidGuard configuration file? [] /usr/local/squidGuard/squidGuard.conf
Do you use c-icap SquidClamav v6.x services? [no] no
Path to squidclamav program? [off] off
What is the user (uid) running Squid or SquidGuard? [squid] squid
Writing Makefile for squidguardmgr
Done...

Now type 'make && make install'

[root@tester squidguardmgr-1.12]# make && make install
cc -o squid_wrapper/squid_wrapper squid_wrapper/squid_wrapper.c
sh install_all.sh

1. Modify Apache httpd.conf to change the running uid and gid to squid user.
2. Modify your httpd.conf to allow access to CGI scripts like follow:

        Alias /squidguardmgr /var/www/squidguardmgr/
       
            Options +ExecCGI
            AddHandler cgi-script .cgi
            DirectoryIndex squidguardmgr.cgi
            Order deny,allow
            Deny from all
            Allow from 192.168.1.24
       

3. If necessary, set additional grants to Squidguard Manager in httpd.conf.
   Restart and ensure that httpd is running.
4. Browse to http://proxy.host.dom/squidguardmgr/ to ensure that things are
   working properly.
