This is Part II of Setup Ubuntu Server in the Cloud series.

4. Install and configure a firewall
Having a firewall in your system is mandatory. Configuring it correctly is even more important. I use 'iptables' for that matter and here is the command to install it, and then check its configuration which, at this time is empty:

dambrosio@XXXCNN4730:~$ sudo apt-get install iptables
dambrosio@XXXCNN4730:~$ sudo iptables -L

I just bought a server in the Cloud to run my development tools (i.e. SVN, JIRA, MySQL etc.). It is a 8.04 Ubuntu server with root access. So I need this server to work the way I want it, so here are the steps I took to prepare it:

1. Change the .bashrc file
I am so used to typing 'll' in the command line as alias for 'ls -lsa' that the first thing I changed was the .bashrc file to have the standard aliases enabled.

Type:

root@XXXCNN4730:/# vi ~/.bashrc

Do you need to check how your website look on combination of browsers under different operating systems? Try entering the URL on the first page of the browsershots website.
Just choose the browsers you want to test under each operating system (no MAC OS available) the browsershots service will produce a series of images which area available online for 30 minutes, but that you can download and save for a more careful analysis.
