Re: [Condor-users] Is it possible to install Condor without root on an NFS mounted /home/dawn/ directory shared by all executing nodes?

Thanks, I tried NO_DNS option and I make all work with IP as Hostname since Condor would treat IP's dot as a domain name split without any complaint.

Condor like to have DNS resolution work in both directions: nodeMgr -> 10.0.0.1 AND 10.0.0.1 -> nodeMgr. If you can't fix this, you can try the NO_DNS options.

Best,
