Re: [Condor-users] Why so many ports?

[Matt Baker <bakerspage@xxxxxxx>]

Thank you, I've read all of the literature you've provided me last  
week. They all went a long way in helping me understand some of the  
communication necessary for firewall traversal techniques.

Basically, I'm at the point of testing Condor-C, but I need to know  
how many / which ports I need to open when a job is moved from one  
schedd to a remote schedd.
