From tshark man page: http://www.wireshark.org/docs/man-pages/tshark.html

TShark is a network protocol analyzer. It lets you capture packet data from a live network, or read packets from a previously saved capture file, either printing a decoded form of those packets to the standard output or writing the packets to a file. TShark‘s native capture file format is libpcap format, which is also the format used by tcpdump and various other tools.

Let’s say you want to convert file testing_diameter.pcap to text file, from Windows CMD or *nix terminal run below command:

tshark -nr testing_diameter.pcap -T text -V > testing_diameter.text

This command will convert full .pcap file include the header into testing_diameter.text

If you only want to convert protocol specified information add -O [protocol] parameter from above command, like below

tshark -nr testing_diameter.pcap -T text -V -O diameter> testing_diameter_only.text

Output diatas muncul karena command prompt yang dibuka tidak menggunakan hak akses Administrator.

Solusinya re-open window command prompt sebagai Administrator, Klik tombol Start di Windows 7 — ketik cmd di Search program and files — klik kanan pada cmd.exe — Run as Administrator.

Untuk bisa menggunakan OpenShift, harus register terlebih dahulu, buka website: https://openshift.redhat.com/app/account/new atau bisa menggunakan account dari redhat.com.
Setelah selesai register, untuk login ke OpenShift console bisa menggunakan link: https://openshift.redhat.com/app/login.

Setelah memiliki account di OpenShift, yang harus dilakukan pertama kalinya adalah:

Install tools untuk client (install rhc di *nix atau windows (windows menggunakan cygwin))

Jika ingin menggunakan GUI, maka login ke https://openshift.redhat.com/app/login untuk masuk ke OpenShift console, tampilan OpenShift management console terlihat seperti gambar dibawah

Langkah dibawah akan menjelaskan cara menggunakan client tools rhc di Linux. Untuk bisa menggunakan rhc harus terlebih dahulu menginstall package rubygems di distro Linux yang digunakan. Proses installasi dari rhc untuk distro berbasis RPM (Fedora/Red Hat)

• Download repo file dari openshift

[anif@anif ~]$ wget -c https://openshift.redhat.com/app/repo/openshift.repo

[anif@anif ~]$ sudo mv openshift.repo /etc/yum.repos.d/

• Install package rhc menggunakan yum

[anif@anif ~]$ sudo yum install rhc
[anif@anif ~]$ rhc –help

Usage: rhc (<resource> | –help) [<command>] [<args>]
Command line tool for performing operations related to your rhcloud account.

List of resources
domain             Manage the namespace for the registered rhcloud user.
app                Manage applications within the rhcloud account.
sshkey             Manage multiple keys for the registered rhcloud user.
port-forward       Forward remote ports to the workstation

See ‘rhc <resource> –help’ for more applicable commands and argumments on a specific resource.

Create Domain Name

Untuk meng-create domain name menggunakan rhc command

[anif@anif ~]$ rhc domain create -n username_anda -l email_anda@xxx.xxx
Password:
Generating OpenShift ssh key to /home/username_anda/.ssh/libra_id_rsa
Generating public/private rsa key pair.

Enter same passphrase again: –> input passphrase yang diinginkan
Your identification has been saved in /home/username_anda/.ssh/libra_id_rsa.
Your public key has been saved in /home/username_anda/.ssh/libra_id_rsa.pub.
The key fingerprint is:
97:cf:6b:0a:30:f4:1a:re:15:81:x3:f6:ef:a3:e4:47 username_anda@host.domain_anda.xx
The key’s randomart image is:

Checking ~/.ssh/config
Could not find /home/username_anda/.ssh/config.  This is ok, continuing
Adding rhcloud.com to ~/.ssh/config
Creation successful

You may now create an application.

Setelah proses create domain selesai, periksa domain yang telah dibuat menggunakan command:

[anif@anif ~]$ rhc domain status -l email_anda@xxx.xxx
Password:
Analyzing system
..Enter passphrase:
…Could not open a connection to your authentication agent.
F.
=================================================
||  Your system did not pass all of the tests  ||
=================================================
1) Either ssh-agent is not running or you do not have any keys loaded.

Seperti di informasikan dari hasil rhc domain status diatas, client yang digunakan untuk koneksi ke openshift tidak lulus semua testing item, dimana detail item yang gagal di informasikan di akhir baris “Either ssh-agent is not running or you do not have any keys loaded.”.
Untuk memperbaiki error yang muncul, dari terminal running command:

[anif@anif ~]$ eval $(ssh-agent)
Agent pid 3811
[anif@anif ~]$ ssh-add .ssh/libra_id_rsa
Enter passphrase for .ssh/libra_id_rsa: –> input passphrase yang di isi waktu create domain
Identity added: .ssh/libra_id_rsa (.ssh/libra_id_rsa)
[anif@anif ~]$ rhc domain status -l email_anda@xxx.xxx
Password:

=========================================================
||  Congratulations, your system has passed all tests  ||
=========================================================

Setelah prosess domain dan system verification testing OK, yang perlu dicreate adalah applikasi yang akan digunakan di openshift. Sebagai contoh disini akan menggunakan applikasi PHP 5.3.

[anif@anif ~]$ rhc app create -a testing -t php-5.3
Password:
Creating application: testing in domain_anda
Now your new domain name is being propagated worldwide (this might take a minute)…
retry # 4 – Waiting for DNS: testing-domain_anda.rhcloud.com
Warning: Permanently added ‘testing-domain_anda.rhcloud.com,23.22.23.80’ (RSA) to the list of known hosts.
Confirming application ‘testing’ is available:  Success!

testing published:  http://testing-domain_anda.rhcloud.com/
git url:  ssh://d6321a174823123e8ca49c0a90a0f1d6@testing-domain_anda.rhcloud.com/~/git/testing.git/
Successfully created application: testing

Command diatas akan membuat local directory “testing” di local computer yang digunakan (di directory aktif yang digunakan ketika menjalankan command rhc app create, sebagai contoh pada command diatas di ~ (home directory).
Sekarang kita akan coba untuk membuat script php sederhana

[anif@anif ~]$ ls
Desktop  Documents  Downloads  Music  Pictures  Public  Templates  testing  Videos

[anif@anif ~]$ cd testing/

[anif@anif testing]$ ls -la
total 32

[anif@anif php]$ ls php/
health_check.php  index.php

[anif@anif php]$ rm php/index.php

[anif@anif php]$ vi php/index.php

buat script sederhana untuk index.php, sebagai contoh:

<!DOCTYPE html>
<html lang=”en”>
  <head>
    <meta charset=”utf-8″>
    <title>Simple php script in openshift</title>
  </head>
  <body>
    <p>Today&rsquo;s is (according to openshift server time zone):
      <?php

      echo date(‘l, F jS Y.’);

      ?>
    </p>
  </body>
</html>

simpan script php diatas, selanjutnya push script index.php ke openshift server menggunakan git. Pastikan directory active berada di “nama_aplikasi_yang_dicreate”, sebagai contoh “testing”

[anif@anif ~]$ cd ~/testing/
[anif@anif testing]$ pwd
/home/anif/testing

commit perubahan yang dibuat ke repository menggunakan command

[anif@anif testing]$ git commit -a -m “testing”
[master 7acda4f] testing
Committer: username_anda <username_anda@host.domain_anda.xxx>
Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:

git config –global user.name “Your Name”
git config –global user.email “you@example.com”

If the identity used for this commit is wrong, you can fix it with:

git commit –amend –author=’Your Name <you@example.com>’

1 files changed, 14 insertions(+), 155 deletions(-)
rewrite php/index.php (99%)

langkah terakhir adalah push perubahan tersebut ke openshift server menggunakan command

[anif@anif testing]$ git push

1. yum-presto
   plugins ini sangat berguna jika untuk mempercepat process download package pada saat update package dari repositories yang mengaktifkan presto meta data. Karena plugins ini hanya akan mendownload delta RPM (hanya download versi yang berubah/berbeda di repositories dengan yang terinstall disystem).
   Process download akan menjadi lebih cepat karena tidak perlu mendownload keseluruhan package. Kelemahannya adalah karena yang didownload tidak keseluruhan package, maka pada saat delta RPMselesai didownload, yum harus melakukan rebuilt ulang package untuk membuat full package yang menjadi update dari package yang terinstall, process ini akan memakan resources CPU. Karena pada saat ini speed CPU sudah sangat cepat sehingga kelemahan dari plugins ini tidak begitu terasa, karena keuntungan dari penggunaan plugins ini adalah bisa menghemat bandwith, mempercepat process download, terutama untuk pengguna internet dengan system kuota, jika tadinya untuk update harus download 100 MB, dengan plugins ini mungkin hanya perlu download 20 MB.Yum plugins configuration ada di /etc/yum/pluginconf.d/

   [root@anif ~]# ls -l /etc/yum/pluginconf.d/

   Untuk meng-query yum plugins yang ada di repository, gunakan command “yum search yum“.
   Setelah yum plugins diinstall, file configuration dari plugins ini akan muncul di /etc/yum/pluginconf.d/

   [root@anif ~]# ls -l /etc/yum/pluginconf.d/

   -rw-r–r– 1 root root 611 May  1  2009 presto.conf

   Jika dilihat isi dari file configuration, maka akan ada “enabled=1” yang berarti plugins tersebut aktif.

   [root@anif ~]# more /etc/yum/pluginconf.d/langpacks.conf

   Description : Yum-langpacks is a plugin for YUM that looks for langpacks for
   : your native language for packages you install.

3. refresh-packagekit
   plugin ini digunakan untuk mengupdate metadata dari PackageKit secara otomatis setiap kali yum dijalankan.

1. Restart your Fedora 15, from grub menu select Fedora 15, then press “e“. Use arrow key to select second line (start with “kernel … “) and then press “e” to edit
   
   

   Reset root Password

2. Add “single” at the end of line and press “ENTER” to go back.
   

   Reset root Password

3. After back to previous grub screen (see first picture), press “b” to boot into Fedora 15. Now Fedora 15 will read option “single” this parameter will boot Fedora 15 to single mode and drop us to shell with root account. Wait until boot process finish and show shell prompt.
4. From single mode shell, type “passwd” and input your new password for “root”
   

   Single Mode

   Reboot Fedora 15 with new root password, from shell enter “reboot” command. Now you can use new root password for Fedora 15.

1. Uninstall package
   Digunakan untuk melakukan uninstall package yang diinginkan, jika package yang diuninstall memiliki dependencies dengan package lain, maka package tersebut juga akan ikut di uninstall. Untuk uninstall package gunakan “yum erase/remove packages_name“.
   Yum tidak bisa digunakan untuk uninstall package yum itu sendiri, jika dilakukan maka akan muncul error

   Error: Trying to remove “yum”, which is protected

   Seperti terlihat pada output dibawah, yum akan uninstall semua package yang memiliki dependencies, dimana yang di uninstall hanya package NetworkManager, tapi yum juga ikut uninstall package lain yang memiliki dependencies dengan NetworkManager.

   Summary     : A network traffic probe similar to the UNIX top command
   URL         : http://www.ntop.org
   License     : GPLv2 and BSD with advertising
   Description : ntop is a network traffic probe that shows the network usage,
   : similar to what the popular top Unix command does. ntop is based
   : on libpcap and it has been written in a portable way in order to
   : virtually run on every Unix platform and on Win32 as well.
   :
   : ntop users can use a a web browser (e.g. netscape) to navigate
   : through ntop (that acts as a web server) traffic information and
   : get a dump of the network status. In the latter case, ntop can be
   : seen as a simple RMON-like agent with an embedded web interface.
   : The use of:
   :
   :     * a web interface
   :     * limited configuration and administration via the web
   :       interface
   :     * reduced CPU and memory usage (they vary according to network
   :       size and traffic)
   :
   : make ntop easy to use and suitable for monitoring various kind of
   : networks.
   :
   : ntop should be manually started the first time so that the
   : administrator password can be selected.

Yum digunakan untuk meng-query informasi dari package, men-download package dari repository, melakukan installasi package, uninstall package, meng-update system. Yum secara otomatis akan memeriksa dependencies dari package waktu melakukan process installasi, uninstall atau update dan secara otomatis juga akan menginstall, uninstall atau update package yang dibutuhkan.

Jika pernah menggunakan rpm untuk menginstall package, mungkin pernah melihat output berikut

[root@anif ~]# rpm -ivh supertuxkart-0.7-2.fc15.i686.rpm
error: Failed dependencies:
libIrrXML.so.1.7 is needed by supertuxkart-0.7-2.fc15.i686
libIrrlicht.so.1.7 is needed by supertuxkart-0.7-2.fc15.i686
opengl-games-utils is needed by supertuxkart-0.7-2.fc15.i686
supertuxkart-data = 0.7 is needed by supertuxkart-0.7-2.fc15.i686

rpm command tidak bisa secara otomatis menginstall package-package yang dibutuhkan oleh supertuxkart-0.7-2.fc15.i686.rpm, sehingga pada saat installasi akan gagal karena dependencies package tidak terpenuhi.
Hal yang berbeda jika kita menggunakan yum untuk menginstall program supertuxkart, dimana yum secara otomatis akan mendeteksi package yang dibutuhkan dan menginstallnya

[root@anif ~]# yum install supertuxkart

Is this ok [y/N]:

terlihat dari output diatas, tidak hanya package supertuxkart yang diinstall, tapi juga package lain yang dibutuhkan oleh program supertuxkart juga ikut diinstall oleh yum.

Package source yang digunakan oleh yum untuk mendownload packages yang akan diinstall dikenal dengan nama repositories. Repositories ini bisa berupa package source local (jika terdapat banyak PC menggunakan Fedora, maka bisa di configure repository local sehingga akan bisa menghemat bandwith internet), bisa juga menggunakan packages source online dari repositories resmi fedora.
Jika menggunakan repositories default setelah installasi Fedora 15 yang ada di /etc/yum.repos.d, untuk bisa melakukan install, update atau searching package harus terkoneksi dengan internet.

• yum konfigurasi file
  konfigurasi yum terdapat pada /etc/yum.conf, sedangkan file konfigurasi untuk repositories terletak pada /etc/yum.repos.d.
  ada banyak options yang bisa digunakan pada /etc/yum.conf yang mengatur yum. Untuk melihat options yang bisa digunakan oleh yum.conf dari command line gunakan perintah

  man yum.conf

  Direktori /etc/yum.repos.d digunakan untuk menyimpan file konfigurasi repositories, disini berisikan list server yang akan digunakan oleh yum. File-file konfigurasi repositories yang terdapat /etc/yum.repos.d menggunakan .repo extension yang dikenal dengan nama .repo file. Untuk melihat daftar repositories yang ada di /etc/yum.repos.d gunakan ls command.

  [anif@anif ~]$ ls -l /etc/yum.repos.d/
  total 48
  -rw-r–r– 1 root root  179 Jul 26  2007 adobe-linux-i386.repo

  -rw-r–r– 1 root root 1305 May 17  2009 rpmfusion-nonfree-updates-testing.repo

Untuk melihat isi file .repo gunakan vi atau gedit text editor, bisa juga langsung menggunakan command more atau less

[anif@anif ~]$ more /etc/yum.repos.d/fedora-updates.repo

• yum cache dan log file
  yum cache path bisa diketahui dari variable cachedir pada /etc/yum.conf, defaultnya ada di /var/cache/yum

  cachedir=/var/cache/yum/$basearch/$releasever

yum log file bisa dilihat di /var/log/yum.log. File yum.log ini me-record semua transaksi yang terjadi baik itu untuk file yang di update, di install atau di uninstall. Untuk bisa melihat isi dari yum.log harus menggunakan hak akses sebagai root.

[anif@anif ~]$ su -c ‘cat /var/log/yum.log’

• Create repo
  Untuk meng-create Fedora repositories, terlebih dahulu harus menginstall packages createrepo. Setelah package ini terinstall, copy semua file rpm yang didownload ke direktori seperti /home/local_repo/f15.
  Running command berikut untuk create file dan generate file yang dibutuhkan:

  [root@anif ~]# createrepo –database /home/local_repo/f15/
  Spawning worker 0 with 1 pkgs
  Workers Finished
  Gathering worker results

  Saving Primary metadata
  Saving file lists metadata
  Saving other metadata
  Generating sqlite DBs
  Sqlite DBs complete

  Untuk bisa menggunakan file rpm yang ada di repo yang sudah dicreate ini, create file .repo di /etc/yum.repos.d, misalkan filenamenya adalah anif.repo,

  # vi anif.repo
  [anif]
  name=anifLocal Repo F15
  baseurl=file:/home/local_repo/f15

  sample file diatas adalah minimal value yang harus ada di file .repo
