RARun fails on remote Linux agent

I've finally managed to get past my authentication issues in connecting
to a Linux RA agent from Win2k.

My new problem is that any commands I run fail.

My script:
Dim process_id, number
RAConnect "edwteam", 1096, "ridoutb", "xxxxxx"
RARun "/usr/local/backup.sh", process_id
RADisconnect

I found a couple threads with similar issues here on the forum.
http://www.softtreetech.com/cgi_bin/config.cgi?noframes&read=6211

The advice here was to run this:
Dim server_listening, boolean
PingPort "edwteam", 1096, server_listening
MessageBox server_listening

It returns TRUE for me.

I run the ra_server using this:
./server.sh -p 1096 of log.txt

log.txt contains:
14 Jul 2005 11:54:17 INFO [run]: start
14 Jul 2005 11:54:17 INFO [authenticate]: start. user = ridoutb
14 Jul 2005 11:54:17 INFO [authenticate]: end. result = OK
14 Jul 2005 11:54:17 ERROR [run]: java.lang.RuntimeException: worker.sh execute failed!
14 Jul 2005 11:54:17 INFO [run]: end

Permissions:
-rwxr-xr-x 1 root root 115 2005-02-03 17:43 server.sh
-rwxr-xr-x 1 root root 140 2005-02-03 17:43 worker.sh
-rwxr-xr-x 1 root root 57 2005-07-13 15:55 runner.sh

My SYSLOG is empty. No output at all.

It looks like worker.sh is failing to execute my commands,
but I have no insight as to why. Any help would be greatly appreciated!

Thanks,

Please make sure that .sh files (if they were transfered from Windows or edited locally) have only end-of-lines and no carriage returns.

To ensure worker.sh is working try running it from shell as "./worker ls"

The files look ok. No ^Ms or anything.

I tried:
./worker.sh
./ worker.sh ls (.sh seems to be required)

Output follows:
root@edwteam:/opt/ra_server # ./worker.sh
su: invalid option -- l

- make this a login shell

-c, --command=

pass command to the invoked shell using its -c

option

-m, -p, --preserve-environment

do not reset environment variables, and keep the

same shell

-s, --shell=

use shell instead of the default in /etc/passwd

It seems like the "-l" in "exec su -l $1 -c "$2/bin/java..." was causing a problem.
I removed it and my job now works! Hurray!

It still may help me and others to know why that -l was a problem, but I am happy to have a successful job run. Thank you for the assistance!

What did you get in the worker.sh file? Which Linux version are you running?

Oh, I see now, this is Java agent using password-based security. I though you are using the native code version.

1. To enable SYSLOG you need to add -s option to the agent start command. here is an example
./server.sh -p 1096 -f log.txt -s

2. Make sure you are starting the server as root so that it can use the "su" command for user sessions to set the user account environment to the process user.

: Contents of my worker.sh file: #!/bin/sh
: exec su -l $1 -c "$2/bin/java -Draserver.path=$3 -cp
