DevOps – Comparison of different Configuration Management Software

By Arun Bagul | September 25, 2017 | Comments 0 Comment

Introduction-

I’m working as DevOps since 2010. Many colleagues, friends asked me about comparison of different Configuration Management Software like Chef, Puppet or Ansible/Salt etc.

It is very important and difficult task to choose right CM(configuration management) software for managing Infrastructure and Application deployments.

I’m attaching pdf file with comparison of different CM hope it will help you.

Document – Devops-Comparison-v3

NOTE: This comparison is purely based on my knowledge and experience. Please feel free to share your updates.

Thank You,

Nagios daily and weekly Reporting and log parsing

By Arun Bagul | August 12, 2011 | Comments 2 comments

Introduction – We wrote perl script for Nagios daily and weekly Reporting. This script is parsing nagios.log for all alerts notification and generating nagios report in CSV format…

** How to use?

arunb@arunb:~$ perl /home/arunb/nagios-log-parsing.pl
* Usage: /home/arunb/nagios-log-parsing.pl { <nagios_log file> [ –summary ] }
arunb@arunb:~$

** To Generate Daily Nagios Report –
arunb@arunb:~$ perl /home/arunb/nagios-log-parsing.pl /usr/local/nagios/var/nagios.log
arunb@arunb:~$ perl /home/arunb/nagios-log-parsing.pl /usr/local/nagios/var/nagios.log –summary

arunb@arunb:~$ perl /home/arunb/nagios-log-parsing.pl /usr/local/nagios/var/nagios.log –summary > /tmp/NAGIOS-daily.csv

** To Generate Weekly Nagios Report –

Add all weeks nagios.log files absolute path (per line) in file say “/tmp/nagios-logfile”

arunb@arunb:~$ for i in `cat /tmp/nagios-logfile`; do perl /home/arunb/nagios-log-parsing.pl $i; done | grep -v ^$ > /tmp/NAGIOS-weekly.csv

Cryptez vos mails avec GPG et Enigmail plugin Thunderbird

By Arun Bagul | November 20, 2009 | Comments 0 Comment

Introduction ~

GNU Privacy Guard (GnuPG ou GPG) est open source / logiciel libre de cryptage et un outil de signature, alternative à la Pretty Good Privacy (PGP) La suite de logiciels de cryptographie. Enigmail est une extension pour Mozilla Thunderbird et d’autres applications Mozilla. Elle fournit la clé publique de chiffrement des e-mail. Fonctionnalité cryptographique est gérée par GNU Privacy Guard (GnuPG ou GPG).

Step 1] Installer GnuPG ou GPG —

* Ubuntu / Debian ~

root @ Arun: ~ # apt-get install gnupg gnupg2

* Redhat / Fedora ~

root @ Arun: ~ # yum install gnupg gnupg2

Etape 2] Comment faire pour installer Enigmail?

Je suppose que Mozilla Thunderbird est déjà installé sur votre système. Pour installer “Enigmail” suivre les étapes suivantes

a) Télécharger “Enigmail” de l’URL »http://enigmail.mozdev.org/download/”

Note ~ OS sélectionner et de Thunderbird version correctement.

b) Dans la barre de menu de la fenêtre principale de Thunderbird vous pourrez voir «Outils». Sélectionnez cette option, puis «Add-ons” option. Ceci ouvrira une nouvelle fenêtre répertoriant tous vos plug-ins Thunderbird. Dans le coin inférieur main de cette nouvelle fenêtre vous verrez un bouton “Installer”. Cliquez sur ce bouton. Dites Thunderbird où vous avez enregistré le Enigmail. Fichier XPI. et dire simplement “Installer” that’s it!!

* Once “Enigmail est installé redémarrer le Thunderbird. Ensuite, vous verrez “OpenPGP onglet” dans le menu principal de Thunderbird.

Etape 3] Configuration privée / clé publique ~

Enigmail utilise la cryptographie à clé publique pour assurer l’intimité entre vous et vos correspondants. Pour générer les Clés publiques / privées, il ya deux méthodes, soit les créer avec l’aide de “gpg” outil de ligne de commande ou utilisez “Enigmail” ….

* Nous produirons privé / public des clés cryptographiques, avec l’aide de «Enigmail», comme indiqué ci-dessous ….

a) Cliquez sur “OpenPGP” dans la barre de menus de la fenêtre principale de Thunderbird. Sélectionnez “Key Management”.
b) Dans Enigmail Key Manager ~ cliquez sur “Générer” onglet dans la barre de menu et sélectionnez “Nouveau paire de clés».
c) Tout en haut de la fenêtre vous verrez une zone de liste déroulante affichant toutes vos adresses e-mail. GnuPG sera associer votre nouvelle clé avec une adresse email.
Enigmail vous demande simplement de quelle adresse vous souhaitez utiliser pour cette clé. Choisir celles qui compte sera de recevoir du courrier crypté.

REMARQUE ~ Nous pouvons utiliser les mêmes touches pour plusieurs comptes.

d) Vous pouvez utiliser une phrase secrète ou il suffit de cocher “Pas de mot de passe” dans la case pour générer des clés sans passphrase.
e) Créer le répertoire pour sauver “La révocation des certificats” …

arunsb arun @: ~ $ mkdir / home / arunsb / .gpg_key /

f) Cliquez sur “Générer clé” pour générer des clés. c’est fait ..

Pour partager facilement les touches, vous pouvez publier vos clés avec serveur de clés.

a) Dans “Key Management” fenêtre Sélectionner vos clés, puis cliquez sur l’onglet ‘serveur de clés “dans le menu principal, puis cliquez sur” Upload clés publiques ”
Note ~ veillez à cocher «Afficher toutes les touches par défaut” case à cocher (à la liste de toutes les touches)

Étape 4] Composez le courrier et signer ~

Composez le mail et dites-Enigmail à le signer. En haut de votre fenêtre de composition, vous verrez un bouton de lecture “OpenPGP”. Cliquez sur cette question. Assurez-vous que le “Sign” option, et seulement cela, est cochée. Enfin “Envoyer” le courrier! (Vous serez invité à fournir votre mot de passe. Une fois que vous y entrer, Enigmail signerez votre e-mail et envoyez-le si vous avez générer des clés avec passphrase sinon il ne sera pas demander)
/ pgp_enigmail-composer

Enjoy!

** EVDO ?

EVolution-Data Optimized (EVDO) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. It uses multiplexing techniques including code division multiple access (CDMA) as well as time division multiple access (TDMA)
to maximize both individual user’s throughput and the overall system throughput. It is standardized by (3G) 3rd Generation Partnership Project 2 (3GPP2) as part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world – particularly those previously employing CDMA networks.

How to configure Reliance Broadband+ Netconnect –

Step 1] Mount USB file system to “/proc/bus/usb” –

root@laptop:~# ls /proc/bus/usb/
root@laptop:~#

* It shows that usbfs is not mounted on “/proc/bus/usb”. To mount run following command….

root@laptop:/var/src/usb_modeswitch-1.0.5# mount -t usbfs none /proc/bus/usb
root@laptop:/var/src/usb_modeswitch-1.0.5# ls /proc/bus/usb/
001 002 003 004 005 006 007 devices
root@laptop:/var/src/usb_modeswitch-1.0.5#

Step 2] Get the status of Reliance Broadband+ USB device ~

* lsusb list USB devices connected to PC as well as information about USB buses in the system and the devices connected to them.

* Output before connecting Reliance Broadband+ Netconnect usb modem –

root@laptop:~# lsusb

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
…..
root@laptop:~#

* Let’s connect Reliance Broadband+ Netconnect! usb modem –

root@laptop:~# lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

root@laptop:~#

*** Reliance Broadband+ EVDO USB is detected as “USB storage device” as shown above…

Step 3] How to use Reliance Broadband+ Netconnect as USB Modem –

To use Reliance Broadband+ usb as USB Modem. We need to switch the usb mode of this device with the help of “usb_modeswitch” tool.

Download ~ http://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.5.tar.bz2

Help – http://www.draisberghof.de/usb_modeswitch/

* Download and extract the “usb_modeswitch” –

root@laptop:/var/src# wget -c http://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.5.tar.bz2

root@laptop:/var/src# tar xvfj usb_modeswitch-1.0.5.tar.bz2

* Now compile and install –

root@laptop:/var/src/usb_modeswitch-1.0.5# gcc -l usb -o usb_modeswitch usb_modeswitch.c
root@laptop:/var/src/usb_modeswitch-1.0.5# make install
mkdir -p /usr/sbin
install ./usb_modeswitch /usr/sbin
mkdir -p /etc
install –mode=644 ./usb_modeswitch.conf /etc
root@laptop:/var/src/usb_modeswitch-1.0.5#

**** Now configure USB mode switching –

a) Edit configuration file “/etc/usb_modeswitch.conf” –

Just search for vendor and product id eg (19d2 and fff5) in config “/etc/usb_modeswitch.conf” file….
This file contains most of the details. I choose following setting and that work’s for me

root@laptop:~# cat /etc/usb_modeswitch.conf

###################
# ZTE AC8710
#

DefaultVendor= 0x19d2
DefaultProduct= 0xfff5

TargetVendor= 0x19d2
TargetProduct= 0xfff1

MessageContent=”5553424312345678c00000008000069f030000000000000000000000000000″

root@laptop:~#

b) Now run “usb_modeswitch” command to switch the mode of USB device –

root@laptop:~# usb_modeswitch -c /etc/usb_modeswitch.conf

Step 4] Load “usbserial” module

* Remember in Ubuntu 09.04 the “usbserial” is buildin kernel. To load that module we need to modify “grub.conf” or “menu.lst” GRUB config file

root@laptop:~# cat /boot/grub/menu.lst

title        Ubuntu 9.04, kernel 2.6.28-11-generic
uuid        c98db8a7-0a2e-4cea-b9d5-43a30c892fb0
kernel        /vmlinuz-2.6.28-11-generic root=/dev/sda5 ro quiet splash usbserial.vendor=0x19d2 usbserial.product=0xfff1
initrd        /initrd.img-2.6.28-11-generic
quiet
….
……
root@laptop:~#

**** Reboot the machine and run the following command

* Output before switch….

root@laptop:~# lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 023: ID 19d2:fff5

How to configure vpn client on Linux

By Ravi Bhure | June 23, 2009 | Comments 1 comment

This has been tested under RHEL 4/5, CentOS 4.4/5 and fedora 8 (kernel version 2.6.15+)

I found and stored few required rpm packages from various places that you will download from given.

http://www.4shared.com/file/113579629/ee5e0aed/libglade-017-11i386.html
http://www.4shared.com/file/113579642/2fd674e3/libglade-devel-017-11i386.html
http://www.4shared.com/file/113579654/dfaee097/libxml-1817-8i386.html
http://www.4shared.com/file/113579677/7491d3af/libxml-devel-1817-8i386.html
http://www.4shared.com/file/113579714/ba004fa4/php4-pcntl-449-1fc5i386.html
http://www.4shared.com/file/113579747/5e7eea5b/php4-pcntl-gtk-102-4fc5i386.html
http://www.4shared.com/file/113579758/d7dac68b/pptp-172-3fc5i386.html
http://www.4shared.com/file/113579764/f541d963/pptpconfig-20060821-1fc5noarch.html

After downloading these first you will have to install lib packages and then pptp packages

rpm -ivh –nodeps libglade-0.17-11.i386.rpm libglade-devel-0.17-11.i386.rpm libxml-1.8.17-8.i386.rpm libxml-devel-1.8.17-8.i386.rpm

rpm -ivh pptp-1.7.2-3.fc5.i386.rpm pptpconfig-20060821-1.fc5.noarch.rpm php4-pcntl-gtk-1.0.2-4.fc5.i386.rpm php4-pcntl-4.4.9-1.fc5.i386.rpm

now go to the given image that I would like to show how I added vpn connection

1) open vpnclient configuration launchpad with “pptpconfig”

2) Now create your profile with all the details and add

Now you have to set you external route or tunnel IP range into it for that click on “Routing” and set “All to Tunnel” and update your profile.

Now start your vpn client.

    ./configure --prefix=/usr/local/openlsm --with-mysql=/usr/bin/mysql_config --enable-internal-pcre
    --with-geoip=/usr --with-ldap=/usr 	

   make
   make install

step 2) openLSM is using 'openlsm' user and group. please create system user and group and set homedir
    /usr/local/openlsm or 'prefix' value. Confirm ownership/permission of '/usr/local/openlsm'
     directory after installation.

  addgroup --system openlsm
  adduser --system  --home /usr/local/openlsm --shell /bin/false --gid <gid_of_openlsm_group>  openlsm

step 3) How to create a self signed certificate for SSL/TLS

 dd if=/dev/random  of=/tmp/random.dat bs=1024 count=1

 $ openssl genrsa   -out  /usr/local/openlsm/etc/openlsm/ssl/openlsm-certificate.key
    -rand /tmp/random.dat 2048
 $ openssl req -new -key /usr/local/openlsm/etc/openlsm/ssl/openlsm-certificate.key
   -out /usr/local/openlsm/etc/openlsm/ssl/openlsm-certificate.csr

 #generate certificate
 $ openssl x509 -req -days 365 -set_serial 1 -in
  /usr/local/openlsm/etc/openlsm/ssl/openlsm-certificate.csr
   -signkey /usr/local/openlsm/etc/openlsm/ssl/openlsm-certificate.key
   -out /usr/local/openlsm/etc/openlsm/ssl/openlsm-certificate.crt

step 4) please check permission, ownership of /usr/local/openlsm directory and file
        path in openlsm.conf  configuration file...

start openlsm with script in contrib directory…

./contrib/openlsm start

URL ~ http://<server_name_or_ip>:4050/ or

http://<server_name_or_ip>:4060/

enjoy !!
