[AG-DEV] Toolkit.CmdlineApplication.instance().GetHostname() question

Eric

I don't have any more info for this problem, as it occurred on another
system that I don't have access too.

But thanks for the feedback, I will keep the info handy if I ever come
across the problem again.

Cheers,
Jason.

Toolkit.CmdlineApplication.instance().GetHostname() question

Hi Jason,
It's checked in AccessGrid/Config.py
   in the SetHostname() function.

Normally, it's checked with socket.getfqdn() and then verified that it's

valid.  Otherwise the localhost ip address is used.

It can be overridden by setting the environment variable "AG_HOSTNAME" 
to an ip address or hostname before launching an AG application.


Often the problem you're seeing means the network isn't configured with 
a matching (usually static) ip address and hostname.  Let us know if you

find out any more details or if the code isn't working correctly.
