Sometimes you need to have access to a computer within some network for different purposes: remote assistance, server administration, play network games with people behind firewall 🙂
For those cases Hamachi is what you need.
So, the following are steps what to do:
1. install hamachi from here https://secure.logmein.com/US/labs/ (I have 64-bit Ubutnu so I downloaded 64-bit deb file)
sudo dpkg -i logmein-hamachi_2.0.1.15-1_amd64.deb
2. install haguichi with this commands:
sudo add-apt-repository ppa:webupd8team/haguichi sudo apt-get update sudo apt-get install haguichi
3. run haguichi (this is GNOME version, graphical)
After that you can create your own networks or join to some other networks
