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
