Re: [Condor-users] uid issues with condor master

Thanks Alan.

I have attached a few more information for your reference. It looks like
I am able to get the current logged on user as well as the host name
alright. (attached code to verify the same). Networking is also fine and
there doesn't seem to be any problem with connecting to the machine,
also other programs which bind to tcp ports like sshd & httpd are
functioning properly.

That looks really suspicious to me. 0.0.0.0 is not normally a good IP
address. Do you have problems in how your network configuration is set
up.?

There are a few causes for this, none of which are documented. Condor
tries to find the current user name as well as the host name, and if
either fail, then you get this message.
