Re: [Condor-users] Ports

The ports used are described in the followng document, note that one of the two fixed
ports is now user-defined (negotiator I think).
In my experience it is simpler to have the same ranges everywhere since complexity doesn't
mix well with security (nor firewalls).

Subject: [Condor-users] Ports


I am a graduate student at the University of Delaware and we have just installed a condor pool in our lab. It was a little rough at first but I was able to get all the machines connected and communicating. The only problem is that I had to open a wide range of ports on each machines firewall in order to achieve this. 

1. Is there a rule of thumb for how many ports to open for each machine?
  a. Manager
  b. Submit
  c. Execute

2. Is there a way to only open them to my sub-domain so that only my computers can access those ports?

So far I opened a range of ports on all the machines for both UDP and TCP. But I don't feel comfortable with this set up. What can I do to be more secure?

I have about 20 computers in the pool.
