[Condor-users] Negotiation Cycle between Linux master and WindowsXP pool

[Rob <spamrefuse@xxxxxxxxx>]

Hello,

In order to learn the condor configuration, I have set up a a mini-condor pool in my office
with an Intel/Linux PC as the central master, and a single Intel/WindowsXP PC in the pool.
The Linux / Windows PCs have IPs 125.125.120.72,  125.125.120.71, respectively

I have installed Condor on Windows XP, in the recommended "UWCS" configuration.
On Linux, Condor comes from the precompiled rpm package provided by the yum repository.

In the local config file, I have configured the Windows pool PC to always run condor jobs.
When I submit a job, I expected it would run right away, but it doesn't. See details below.
I'm not sure why the job is not ran; in the NegotiatorLog file there is the 127.0.0.1 IP numbers
as the IP of the submitter. Is that causing the trouble?
Do I have to add 127.0.0.1 somewhere in the local config files?

I hope someone can point out where I should look for solving this problem!
Thanks!


The local configuration files on the two machines are:
# Linux master:
CONDOR_DEVELOPERS = NONE
COLLECTOR_NAME = Library Pool
COLLECTOR_HOST  = $(FULL_HOSTNAME)
DAEMON_LIST = COLLECTOR, MASTER, NEGOTIATOR, SCHEDD
NEGOTIATOR_INTERVAL = 20
TRUST_UID_DOMAIN = TRUE
HOSTALLOW_WRITE    = *
HOSTALLOW_READ = *
LOWPORT = 9600
HIGHPORT = 9700


# Windows pool PC
COLLECTOR_NAME = Library Pool
HOSTALLOW_WRITE = *
HOSTALLOW_READ = *
DAEMON_LIST = MASTER STARTD
HOSTALLOW_ADMINISTRATOR = 125.125.120.72
CONSOLE_DEVICES = mouse, console
LOWPORT = 9600
HIGHPORT = 9700 
WANT_SUSPEND = TRUE
WANT_VACATE = FALSE
START = TRUE
SUSPEND = FALSE
PREEMPT = FALSE



On the master I have 5 condor daemons:
 condor_master
 condor_collector
 condor_negotiator
 condor_schedd
 condor_procd


On the Windows pool PC, there are two condor daemons:
 condor_master.exe
 condor_startd.exe


I get status output on the master:

$ condor_status
Name     OpSys    Arch   State     Activity LoadAv Mem   ActvtyTime
Office   WINNT51  INTEL  Unclaimed Idle     0.020   767  0+00:17:53


I made this submit job:

#########
Requirements = (Arch == "INTEL") && (OpSys == "WINNT51") && (HasFileTransfer)
Universe = vanilla
Executable = helloworld.exe
output = helloworld.out
should_transfer_files = YES
when_to_transfer_output = ON_EXIT
Queue

In the NegotiatorLog file the repetitive negotiation cycles complain about some kind
of read/write error, when negotiating with 127.0.0.1...:
