Nutshell: Internet access from inside LXC (affects Selenium) #78

Closed tcrivat closed 9 years ago

tcrivat commented 9 years ago

When using the Nutshell, currently there is no Internet access from inside the (LXC) containers. This affects the Selenium service which downloads the selenium jar from the Internet, see the following line in the selenium-agent-start script:

This can be easily fixed by adding the following iptables rule inside the Nutshell VM:

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

So, this rule should be present in the default Nutshell configuration, by adding it to one of the startup scripts or using the iptables-persistent package. Because the Nutshell is @gtato's child, I prefer to let him do the change.

Fixed in d18e449b716010f2a09ded4c3129c3811f893707, now Internet access is allowed inside containers and the Selenium service works in the Nutshell.
