Re: [HTCondor-users] Windows ignoring HIGHPORT/LOWPORT?

[Todd Tannenbaum <tannenba@xxxxxxxxxxx>]

Hi Ben,

For your scenario below, I am curious if setting IN_LOWPORT and 
IN_HIGHPORT instead of setting LOWPORT and HIGHPORT respectively solves 
the problem....

Personally I've never liked LOWPORT/HIGHPORT, since I'd bet that 95% of 
folks really only care about incoming connections (listen port) which 
means better handled via IN_LOWPORT and IN_HIGHPORT.

Hopefully as we move to having the shared_port on by default everywhere, 
nobody will ever have to think about these low-level knobs again.

regards
Todd
