[Condor-users] Dose NFS and real IP matter to install condor?

[Sean <condor.digger@xxxxxxxxx>]

Hi,
  I am trying to install condor in two machines. I successfully install 
condor in both machines, and it runs ok if the job is submit locally and 
run locally.  Below is the submit file.

  Executable     =   hello-cows
  Universe       =   standard
  Output         =   hello-cows.out$(Process)
  Log            =   hello-cows.log$(Process)
  Queue 5

However if I try to specify the job to be run in a certain machine, 
using the submit profile:

  Executable     =   hello-cows
  Universe       =   standard
  Requirements   =   Machine == "172.8.30.2"
  Output         =   hello-cows.out$(Process)
  Log            =   hello-cows.log$(Process)
  Queue 5
It is stuck. when I use condor_q to check the status, the jobs are 
always in the queue and never got run.

I use the same example to run in another runable condor system, and the 
exmaple runs very well. Compare my system and the runnable system, I 
found the differences:
1. The runable system is using real ip, and mine is using local IP 
behind a firewall
2. The runable is using file sharing system, and mine does not have the 
file system running.

Are the realy IP and file sharing system necessary to install condor? if 
no, what I have missed?
Thanks for the answer.

Regards,
Sean
