[Spacewalk-list] Problems with remote commands on some systems

[Edward Dore]

Hopefully someone can help me with some weird behaviour that I'm seeing. I've got a fresh Spacewalk 1.1 install on a CentOS 5 server with multiple CentOS 5 clients (all 64-bit in case it makes a difference for some reason) and three of the registered systems are returning errors when running remote commands.

It doesn't matter what the scheduled remote command is, but 3 of the 20 systems registered to this Spacewalk server always fail whilst the 17 other systems execute the exact same commands perfectly. Here's an example from the System History Event page:

> Summary:	Run an arbitrary script scheduled by ######
> Details:	This action will be executed after 10/ 3/10 6:04:00 PM BST.
> 
> This action's status is: Failed.
> The client picked up this action on 10/ 3/10 6:06:32 PM BST.
> The client completed this action on 10/ 3/10 6:06:34 PM BST.
> Client execution returned "Script failed" (code 1)
> 
> 
> Run as: root:root
> Timeout: 600 seconds
> 
> #!/bin/bash
> echo "test"
> 
> 
> Start Date: 2010-10-03 18:06:32
> End Date: 2010-10-03 18:06:32
> Return Code: 256
> Raw Output: view/download raw script output
> Filtered Output:
> 
> 
> Time:	10/ 3/10 6:06:06 PM BST

The return code is always 256, no matter what the script actually returns. Both the raw output and filtered output are always blank. If I run the script on the host manually then the return code is 0 and there is the same output as on other hosts where it is working through Spacewalk.

These scripts are usually picked up by OSAD, but even if I disable OSAD and manually run rhn_check --verbose there is absolutely no output whatsoever

I've confirmed that all actions are enabled with rhn-actions-control, and even disabled and re-enabled all of them. I've also made sure that /etc/sysconfig/rhn/allowed-actions/script/run exists and has the same permissions as a working system.

I've pretty much run out of ideas at this point, so any help from someone more experienced with Spacewalk would really appreciated.
