Hello,

while adding a HP-UX node to a working Torque/Maui-Linux environment I 
ran into the following problem:
On the HP node qstat,qmgr,pbsnodes etc. is working only sporadically. 
Usually the commands results in the error message (with PBSDEBUG=yes)
 >qstat
pbs_iff:  MSG=cannot authenticate user
ALERT:  cannot read pipe, rc=0, errno=0 (Error 0)
ERROR:  cannot authenticate connection, errno=0 (Error 0)
No Permission.
qstat: cannot connect to server warp31.physik.tu-chemnitz.de (errno=15007)
 >
At the same time the server log says:
10/24/2005 17:28:12;0100;PBS_Server;Req;;Type AuthenticateUser request 
received from cain at nischel1.physik.tu-chemnitz.de, sock=12
10/24/2005 17:28:12;0080;PBS_Server;Req;req_reject;Reject reply 
code=15019( MSG=cannot authenticate user), aux=0, type=AuthenticateUser, 
from cain at nischel1.physik.tu-chemnitz.de

Nevertheless I can send jobs to the HP node when submitting from a Linux 
PBS client or from the PBS Server.

First I thought of a timeout problem. So I increased  tcp_timeout, which 
didn't change anything.

Here is the server setup:

       server_state = Active
       scheduling = True
       max_user_run = 17
       total_jobs = 25
       state_count = Transit:0 Queued:6 Held:0 Waiting:0 Running:19 
Exiting:0
       acl_host_enable = True
       acl_hosts = *.physik.tu-chemnitz.de
       managers = cain@*.physik.tu-chemnitz.de
       default_queue = qsNormal
       log_events = 511
       mail_from = root
       query_other_jobs = True
       resources_assigned.nodect = 19
       scheduler_iteration = 600
       node_ping_rate = 300
       node_check_rate = 600
       tcp_timeout = 30
       job_stat_rate = 30
       pbs_version = torque_1.2.0p2

Help and suggestions are welcome!

Thanks   Philipp.
