Thanks, not a problem getting my node names to display. However, when I try to connect via SSH with Putty, it tells me "Unable to open connection to "hostname.local" Host not found."

When I ran "condor_status -master -af Name 'regexps("<([^:]*)",MyAddress,"\1")'" I received the error "Unknown option -af" and when I eliminated the "-af," the command ran but didn't return anything...

I appreciate your time!

My challenge now is how to change the config file on each compute node...I've never logged into them before. I'm having trouble determining what their IP addresses are, or else I think I could SSH into them with putty and modify the config files. I assume the " condor_config_val -v -startd -name compute-0-0.local EXECUTE" will show me the IP addresses, so I'll start there. Thank you all for your time.

Run "condor_status -master" to see all the hosts (nodes) in your pool.   Note this will display hostnames, like:

   Name                 Version        Cpus   Memory      Uptime    

   node1.wisc.edu       8.6.9.427508      8    15.5 GB   20+02:31:06
   node2.wisc.edu       8.6.9.427508      8     7.7 GB   20+02:31:41
   node3.wisc.edu       8.6.9.427508      8    15.5 GB   20+02:31:58


If you really need IP addresses instead of hostnames, you could do something like:

   condor_status -master -af Name 'regexps("<([^:]*)",MyAddress,"\1")'

which will give output like:

   node1.wisc.edu 10.0.5.22
   node2.wisc.edu 10.0.5.23
   node3.wisc.edu 10.0.5.24
   ..

Todd

This will be what the config files on that node contained at the time the condor_startd was last started or reconfiged - which might be older than what the config files say now.
