Re: [Oscar-users] pbs route queue to different server

Ok, after a little more poking around, I looked through the source, and learned a few things, but I don't think any of that has made too much of a difference yet. I reviewed my server definition, and added ACL host information to the server definition. Now I can submit a job, and perform qstat, but I get a Bad UID message from qsub. I have synced the passwd, group,and shadow files across the machines. I have submitted the job as shown below.

Any thoughts on this, I am sooo close now, thanks for everyone's help.

Ben,
        I'd do this on some other workstation, rather than on the cluster
itself.  Get the src.rpm, install it (rpm -ivh openpbs.src.rpm - check
the name).  You may need to do this as root, if you haven't set up some
rpm macros.  After this, do "rpmbuild -bp openpbs.spec" in the
directory.  At that point you have the patched source, for you to grep
and search in other ways.
        A simple start on it is "find . -type f -exec grep PBSE_BADHOST {}
/dev/null \;" to find the error report and then go searching from there.

How do I dig into the code like you suggest. I am ok to do this, just not sure how to get started.

Ben,
        The last time I came across this sort of thing, I eventually had to
dive into the code and add extra information to find out what and why it
was complaining.  There are about 16 places where the PBSE_BADHOST (i.e.
the error you are getting) can come out.  A lot of those can probably be
dropped as they aren't the right function, but it could be any one of
the rest.
        I don't know if that is an option for you, but it might be something to
consider, even if it is just a code review you do.

I added viper.memphis.edu and borg.memphis.edu to both the clienthosts and to the restricted parts and added the /home entries as well although both systems share a common home directory system. The same error message persists. Ben

Ben,
        Have a look in /var/spool/pbs/mon_priv at the file config.  You may
need to add either the restricted or clienthosts line for them.  See
pbs_mom man page for more details.

I added +viper.memphis.edu to the etc/hosts.equiv on borg.memphis.edu. Viper is the machine that I want to do my job submission from, and borg.memphis.edu is the cluster server.

This is the error message listed in the logs on borg.memphis.edu

03/01/2004 19:09:42;0100;PBS_Server;Req;;Type 49 request received from [EMAIL PROTECTED], sock=11 03/01/2004 19:09:42;0080;PBS_Server;Req;req_reject;Reject reply code=15008, aux=0, type=49, from [EMAIL PROTECTED]

this is the error message I recieved when I tried the qsub on viper:
[EMAIL PROTECTED] bdsimmns]$ qsub -q [EMAIL PROTECTED] surface.pbs
pbs_iff: error returned: 15008
pbs_iff: Access from host not allowed, or unknown host
No Permission.
qsub: cannot connect to server borg.memphis.edu (errno=15007)
[EMAIL PROTECTED] bdsimmns]$
I can ssh to and from the two machines without a password, and they share a common home directory system. I can submit jobs to the queue workq while logged into borg.

Any other thoughts as to things to look for?

Ben,
        Did you add something in /etc/hosts.equiv on the other server
(borg.memphis.edu)?  Anyway, I think that problems with hosts.equiv come
up with a 10523 (Bad User) error.
        What are you seeing in the logs on the other server, i.e.
borg.memphis.edu?  You should either see something logged about the
connection and possibly a rejection, or you would have a deeper level
problem.

ok, here is what I have setup right how: I edited /var/spool/pbs/server_name and set it to the cluster server I edited hosts.equiv and set it to +outside.computer.name This computer is connected through eth1 of the cluster server, so I edited the pfilter.conf to have eth1 all trusted, to ensure that would not play a role for now.

I created the following script and executed it with qsub.
The error message follows below, but is permissions based.
Thanks,

The extra pbs server and routing queue shouldn't be necessary. Try setting up a hosts.equiv on the pbs_server machine which includes the machine you want to run qsub from. Also, on the machine you're running qsub from, set the server_name file appropriately for the remote server. qsub/qstat commands should work then. As I mentioned before though, I'm not positive that the hosts.equiv is all that is necessary, but I am sure that you don't need two pbs_servers.

I already went through that pain to get a username and password there. The way I read through the manuals is that I need a pbs_server running on the machine that I am making the submission from, and that I have a queue defined on this machine as well. This machine's queue is a routing queue, and I can define one or more destination queues. I for now only want it to go to the queue that is on my cluster server, but I will later need to direct it to other clusters around our campus.

I can send you privately the pdf of the admin guide from the site you mentioned, or reference pages I think I am using correctly.

Am I misunderstanding how this is supposed to work to go between different physical machines?
Thanks,
Ben

Ok, I think I set everything up correctly, but when I try to submit a job I get a error that job has been rejected by all possible destinations.

Any thoughts on what I need to look at, or do I need to post the server and queue configs for the machine I am submitting on and the one that is recieving?

Not sure why you would have server/queue configs at all on the machine you're submitting on... shouldn't have a server on there at all, right? I know there are admin guides available at http://www.openpbs.org that may also be of help. You will need to register a user name though. (I had some trouble finding a link to do this there though)

Thanks for the help,

It's been awhile since I looked into it, but I think a hosts.equiv file is needed to allow submission from other hosts. I don't have reliable detail past that at the moment.

Has anyone tried to setup a pbs queue that routes to a different server outside their cluster? Or are most people just having users submit the job on the server that it should be run on?

I am getting many different types of errors, but am looking to see if there is an experience base to draw on here, or if I need to look towards another list,

Thanks to all in advance,
