[X2Go-User] x2go client timeout when x2goagent cannot resolve ip

[Nikolaos Kefalas]

I have an Ubuntu 14.04 x64 system with x2go PPA, where certain users
are restricted from accessing the Internet, but only local network and
loopack access is allowed. When i try to login from a x2go-client from
another system, the client connects to the x2goserver but after while
it timeouts. I suspect that the x2goagent which runs with user uid
tries to resolve the incoming ip and stalls there waiting the reverse
dns lookup to be completed.
Is any way to disable ip address reverse dns lookup for x2goagent?

Best regards,
