Install VLC:

[root@localhost ~]# yum install vlc

Keep Cache Hasil Instal Aplikasi Ubuntu 15.04

Ternyata saat ini, Ubuntu (saya pakai 15.04) mengubah beberapa konfigurasi salah satunya adalah untuk menjaga file hasil instalasi software baik menggunakan apt-get atau synaptic package manager dengan menyediakan file sendiri.

Silahkan ikuti petunjuk dibawah:

rijalhanif@rijalhanif-Vostro-2420:~$ sudo su

root@rijalhanif-Vostro-2420:~# nano /etc/apt/apt.conf.d/20archive

Before:
APT::Archives::MaxAge "30";
APT::Archives::MinAge "2";
APT::Archives::MaxSize "500";

Change to:
APT::Archives::MaxAge "0";
APT::Archives::MinAge "0";
APT::Archives::MaxSize "0";


Dicoba install aplikasi apapun, kemudian cek di directory:

root@rijalhanif-Vostro-2420:~# apt-get install dosbox

root@rijalhanif-Vostro-2420:~# ls -l /var/cache/apt/archives/*.deb
-rw-r--r-- 1 root root 845028 Okt 13  2014 /var/cache/apt/archives/dosbox_0.74-4_amd64.deb
-rw-r--r-- 1 root root 110184 Okt 25  2014 /var/cache/apt/archives/libmikmod3_3.3.7-1_amd64.deb
-rw-r--r-- 1 root root 163052 Sep  9  2014 /var/cache/apt/archives/libopenal1_1%3a1.15.1-5_amd64.deb
-rw-r--r-- 1 root root   8840 Sep  9  2014 /var/cache/apt/archives/libopenal-data_1%3a1.15.1-5_all.deb
-rw-r--r-- 1 root root 162384 Jul  2  2014 /var/cache/apt/archives/libsdl1.2debian_1.2.15-10ubuntu1_amd64.deb
-rw-r--r-- 1 root root  11656 Des 23  2013 /var/cache/apt/archives/libsdl-net1.2_1.2.8-4_amd64.deb
-rw-r--r-- 1 root root  74718 Apr 28  2014 /var/cache/apt/archives/libsdl-sound1.2_1.0.3-7build1_amd64.deb

Dan.. source file .deb nya masih ada dan keep selamanya. :)

Run Others Linux Distro beside Ubuntu

Klo gak begitu ngerti judulnya,, inti nya adalah pasangin beberapa distro linux berbarengan di Ubuntu (native) yang sudah diintall.
Beberapa distro ini bisa  file iso aja intall-an, atau partisi (portable linux).

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)

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:
   /usr/local/BerkeleyDB.4.3/lib

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'

See any operating system documentation about shared libraries for
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

Connect Network (Wired/Wireless/Vpn/Modem) menggunakan Terminal

Yang males nge klik sana-sini, untuk melakukan koneksi internet atau intranet linux anda, dan juga bagi pengguna network manager untuk pengelolaannya? Cara ini merupakan opsi bagi Anda.

Network Manager biasa terdapat pada distribusi linux yang menggunakan gnome sebagai desktop environment and graphical user interface nya.

Cek Port Jaringan

Bagi para sesepuh jaringan mungkin sudah terbiasa dengan hal ini, bahkan mungkin sehari-harinya sering digunakan untuk mengetahui/memonitoring port dalam jaringan mereka.
Di Ubuntu, perintah tersebut dapat menggunakan:

Cek port Telnet [23]
$ netstat -an | grep LISTEN | grep ":23 "

Cek port Http [80]
$ netstat -an | grep LISTEN | grep ":80 "

Cek port Ftp [21]
$ netstat -an | grep LISTEN | grep ":21 "

Selebihnya cek sendiri ya port yang lain,
