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.

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

Copyright 1987-2006, Larry Wall

Perl may be copied only under the terms of either the Artistic License or the
GNU General Public License, which may be found in the Perl 5 source kit.

Complete documentation for Perl, including FAQ lists, should be found on
this system using "man perl" or "perldoc perl".  If you have access to the
Internet, point your browser at http://www.perl.org/, the Perl Home Page.

[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.

Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

more information, such as the ld(1) and ld.so(8) manual pages.

Trash di Terminal

RM mungkin sudah banyak yang tahu, namun mungkin sedikit yang sadar bahwa RM dalam linux itu sama seperti SHIFT+DELETE dalam Win***.
Nah, gimana nih klo kita mau menghapus sementara yang artinya file/folder tersebut memang tidak kita butuhkan kembali namun mungkin sewaktu-waktu mau kita restore. Permasalah tersebut dapat kita atasi dengan cara trash (win: Recycle bin). Saya yakin bagi anda yang sudah kenal Linux, pasti gak asing dengan tempat penitipan sementara itu (baca Trash). Caranya yang simple dalam GUI Linux memang hanya dengan klik kanan, delete. Namun tahukan anda bahwa trash tersebut juga bisa kita operasikan via Terminal?? Woke berikut oprekannya,,

1. Instal paket trash-cli
# apt-get install trash-cli

2. Hapus file dengan trash 
# trash /home/rijalhanif/modul_igos_trainn2013.pdf

3. Tiga utilitas penting, list-trash, restore-trash, empty-trash

4. Cek file apa saja yang ada dalam KOTAK Trash,
# list-trash

2013-01-22 10:33:33 /home/jaya/modul_igos_trainn2013.pdf
2013-01-22 10:33:33 /home/jaya/sample
2013-01-22 10:33:33 /home/jaya/sample1
2013-01-22 10:33:33 /home/jaya/sample2


5. Restore file 
# restore-path


   0 2013-01-22 10:33:33 /home/jaya/modul_igos_trainn2013.pdf
   1 2013-01-22 10:33:33 /home/jaya/sample
   2 2013-01-22 10:33:33 /home/jaya/sample1
   3 2013-01-22 10:33:33 /home/jaya/sample2

What file to restore [0..3]:

Isikan nomor berapa file yang akan direstore [0..3]??

6. Mengosongkan KOTAK Trash
# empty-trash
# list-trash (hasilnya kosong)

--semoga bermanfaat
