Vim set indent

1. edit ~/.vimrc file

vi ~/.vimrc


2. And add this set of commands to the vimrc file.

set expandtab
set shiftwidth=2
set softtabstop=2
filetype plugin indent on


3. Save the changes


iptables -I INPUT -p tcp --dport 3000 -j ACCEPT

should do what you want.


If you want rules saved so after reboot all will be ok, do:

service iptables save

if you want to access without the port (ipaddress:3000) 
run this command

iptables -I INPUT -p tcp --dport 80 -j ACCEPT

then save and reboot:
service iptables save

How to install OTRS on ubuntu 12.04 server

These are steps i followed today and otrs works fine for me


cp otrs-3.2.9.tar.gz /opt/

cd /opt

tar -xzvf otrs-3.2.9.tar.gz

ln -s /opt/otrs-3.0.3 /opt/otrs

useradd otrs
passwd otrs
usermod -d /opt/otrs otrs

usermod -g www-data otrs

sudo apt-get install mysql-server apache2

cd /opt/otrs

sudo ./bin/ | grep Not

sudo aptitude search libdatetime-perl libnet-dns-perl libwp-useragent-determined-perl

sudo aptitude install libdatetime-perl libnet-dns-perl libwp-useragent-determined-perl

sudo bin/ –otrs-user=otrs –otrs-group=otrs –web-user=www-data –web-group=www-data /opt/otrs

sudo ln -s /opt/otrs/scripts/apache2-httpd.include.conf /etc/apache2/sites-available/otrs.conf

sudo ls /etc/apache2/sites-available/

sudo /etc/init.d/apache2 reload

sudo a2ensite otrs.conf

sudo /etc/init.d/apache2 reload


It did not work at this moment. Hence, i followed the remaining from (10.4)

cd /opt/otrs/kernel
cp config/ config/

Modify the ENVVARS file

Add # in front of 

#export Apache_run_user=www-data
#export Apache_run_group=www-data

Below that type :

#export Apache_run_user=otrs
#export Apache_run_group=otrs

Restart Apache and you should be able to complete the registration
