[Condor-users] GCB Socket connection issues (others never had this resolved?)

[Sam Skipsey <sskipsey@xxxxxxxxxx>]

Hi all,

I'm trying to set up flocking between two small condor pools, as a test 
case for a more complicated arrangement, and I'm using a GCB to mediate 
connections, as one of the pools is essentially private (or, at least, 
firewalled enough that it can be regarded as such).

However, after enabling the NET_REMAP variables in condor_config, the 
condor services no longer run on those nodes: the MasterLog having 
errors like

GCB: GCB_bind(6[GCB_SOCKET], 0x7fbffff910-><0.0.0.0:0>): Unable to 
determine local IP address (_myIP failed).
8/13 11:49:19 Failed to bind to command ReliSock
8/13 11:49:19 (Make sure your IP address is correct in /etc/hosts.)
8/13 11:49:19 ERROR "BindAnyCommandPort() failed" at line 8403 in file 
daemon_core.C

My /etc/hosts contains both localhost and also (in a bid to fix this 
issue) an explicit mapping for the network ip of the machine.

I notice, in the archives, that Cor Cornelisse had similar problems, 
which were determined (by them) to be specific to certain NICs. However, 
there was never any conclusion to the matter posted on any threads I can 
find - despite the developers expressing an interest in looking into the 
matter last year.
(See, for example 
https://lists.cs.wisc.edu/archive/condor-users/2007-January/msg00179.shtml )

Does anyone know what the issue is with this? Cor, did you solve the 
issue yourself?
Is this not, in fact, my problem?

Any assistance welcome,
Sam Skipsey
