How to install software on my VPS?

vps
apps

#1

Hello,

Just got the basic version of DreamHost for a VPS, and I create a shell username and logged into the user with my linux computer. I want to start a radio station, so I tried to do “sudo apt-get install icecast2” but this came up…

[ps603812]$ sudo apt-get install icecast2
[sudo] password for jojovoidcore: 
jojovoidcore is not in the sudoers file.  This incident will be reported.
[ps603812]$

so now I am not entirely sure how to get icecast on the server. Is there a way to enable aptitude installation on the vps?
