On VPN PPTP I have Ubuntu Server installed. There are firewall rules setup for outgoing 80/8000/5432 ports, and incoming port 22 is ssh connectable.
To install software with sudo apt-get <package name> it works fine, however whenever I am trying different domains for software installation such as rubygems.com or to pull code from github.com it results in Connection TimeOUT with different relevant errors.
Also I am not a root user however I was granted administrative account on all the ports for the server.
So my question is simple and stupid: How to download stuff from the web on Ubuntu? Should I get open some ports or allow add required URLs to Firewall? If so how to that?
Last but not lease, it is my first experience with sort of Network / Server administration, so sorry if my terminology differs from Guru people. Sometimes it feels that I am working blindly with the system, so if you could provide methods for testing the solution that would be greatly appreciated.
