[HTCondor-devel] Dan, quick question re shared port server

[Todd Tannenbaum <tannenba@xxxxxxxxxxx>]

Hi Dan -

When using the shared port server on the central manager (collector 
machine), things get a little complicated.  Users either need to
  1. open up two ports on their firewall for the central manager (one 
for the collector, one for the shared_port), or
  2. open just one port on their firewall for the shared_port, but then 
they need to edit CONDOR_HOST everywhere on all nodes (including 
flocking), and also intuitive things like "condor_status -pool 
hostname.com" will not work as it used to.
Could we do better?  The simple idea (credit: zmiller) is if the 
shared_port sees a malformed request (e.g. a stream that does not begin 
w/ a proper daemon name), the shared_port would send it to the collector 
by default if a collector is registered.  The hope is this heuristic 
would enable us to run the shared_port on port 9618 everywhere including 
the central manager, and yet no need to modify CONDOR_HOST etc. We wanna 
have our cake and eat it as well.
Possible? Crazy?  If you think it is reasonable/possible, we'll make a 
ticket.
thanks
Todd
