Modelsim crash in ubuntu 12.04

Have installed Quartus 13.0 and ModelSim on Ubuntu 12.04 LTS. Installed from setup.py within the main package found on website.

Can't get ModelSim to work without a fatal crash.

Within ModelSim, every time I click Simulate, then Start Simulation, when I then select the design unit I want to simulate, I click ok, and ModelSim closes.

In the terminal I get the following message:

Error: couldn't open socket: host is unreachable

Trouble making server.

Have installed it in my home directory, and then changed to install as root in /opt/altera. Same problem.

Any help for logs to look at how to get more verbose output to try and track down the problem would be great.

    Further debugging shows that modelsim is trying to connect to a DNS server to do some sort of loop back, but my machine is not sat on the correct domain.

    I can't put it on the correct domain. Is there a way I can stop it from trying to do this loop back over the ethernet?

    Incase anyone else wastes any time trying to get this resolved....

    /etc/hosts needs to have an entry for localhost on loopback.
