Assume that HTCondor is installed and running with the following set up: -The HTCondor schedd is installed on a machine (named S) with IP address 192.168.0.1; this is your submit machine. +*:The submit machine with the condor_schedd is installed on a machine named S with IP address 192.168.0.1. -An HTCondor startd is installed on a machine (named E) at 192.168.0.2; this is your execute node. +*:The execute machine with the condor_startd is installed on a machine named E with IP address 192.168.0.2. -The firewall has an external---that is, facing the Internet---IP address of 10.0.0.1, and an internal---that is, facing toward your local network---IP address of 192.168.0.250; we will call this machine F. We know 10.0.0.1 is actually not a routable address, but pretend that it is for the duration of this document. S and E are in the domain =mydomain.net=. +*:The firewall has an external, Internet facing, IP address of 10.0.0.1, and an internal, local network facing, IP address of 192.168.0.250 on a machine named F. IP address 10.0.0.1 is actually not a routable address, but pretend that it is for the duration of this document. S and E are in the domain =mydomain.net=. Then we will make the following changes to =condor_config.local= on S (the schedd). To find your HTCondor configuration files, the command =condor_config_val -dump= will be a big help, as the files are listed in the header of the output
