update:  I figured out at least this issue.

This may be in the PDF documents, but I missed it.

it seems that:
* both systems must have system users with the same UIG/GID/username
    (something I don't usually make an effort to do)
* if you add a system user, you need to run gbch-user -R to reload the system user list
* finally, run gbch-quit, then gbch-start so that xbnetserv reloads the user list

Please, feel free to correct any misconceptions I have, but this set ot steps got em past my problem.

Thank you!

thanks for your reply.  I have gone so far as to set up identical users on both sides (including UID and GID).  This after looking over the source for rbtr.c

I can't help but think that there's something simple I'm missing.  Can I make GB log connection attempts?

I'm sifting back through the reference manuals to see if I missed anything, but I thought I might get a better answer here.

My setup:
Arch Linux 64-bit on a Linode (cloud server) as the master GNUBatch server
CenttOS 5.x 64-bit on a Linode as a workstation

GNUBatch cloned from the git repo, dated 2010-10-22.
./configure, make, make install (install needed a few minor fixes) on both boxes

What works:
I can submit jobs logged in to the GNUBatch server, either as gnubatch, root, or myself
no issues with GNUBatch - the jobs run as planned

What I can't get to work:
I can't seem to submit jobs to the GNUBatch server from any remote workstation.  I have run
gbch-start on my workstation, and made sure that the services were defined in /etc/services.  I get:

address@hidden ~]$ gbch-rr -Q dev-mongo -u mmoser -T13:57  ./batch
No such valid user on remote devmongo

(I realize that -u is probably redundant, but I get the same response if I don't use it).  I get the same response whether I'm submitting as me (mmoser), root, or gnubatch.

I do have reciprocal entries in etc/gnubatch.hosts:
    my workstation declares dev-mongo with an alias of devmongo
    dev-mongo (the master GNUBatch server) declares the workstation as a host

I hope I've given you enough info, and thanks in advance for any advice.


It does need the user name set up on the remote system to be roughly the same.

I have put in code recently to overcome that requirement and I'll put it up hopefully in the next month or so together with a whole raft of other stuff, notably a new MS Windows client suite.
