You need three things:
 1) (in Fedora system's condor_config) indicate the Fedora system is a 
Central Manager by adding COLLECTOR and NEGOTIATOR to the DAEMON_LIST
  e.g. DAEMON_LIST = COLLECTOR, MASTER, NEGOTIATOR, SCHEDD, STARTD
 2) (in Windows condor_config) set the COLLECTOR_HOST to the Fedora 
system's name and only have MASTER and STARTD in its DAEMON_LIST
  e.g. COLLECTOR_HOST = <name or IP of Fedora system)
       DAEMON_LIST = MASTER, STARTD
 3) (on both) make sure they are authorized to talk to each other
  e.g. HOSTALLOW_READ = * and HOSTALLOW_WRITE = *

Step 3 doesn't make for a particularly secure configuration, but you can 
always adjust it after you get going.

The condor_procd is a program Condor daemons start to assist in their 
function. You shouldn't have to worry about it. It isn't related or a 
replacement for the negotiator or collector.
