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

[Edward Dore]

Mike,

Yeah, if I run the scripts manually from bash via SSH then they run as intended and give the expected output (they are the initial system configuration scripts scheduled by dell-satellite-sync to work out which channels to subscribe a system to, but even if I schedule a simple echo command then it fails with the same 256 return code and no output).

SELinux is set to permissive mode, so shouldn't be interfering with anything.

Generally all of the working and non-working systems are near identical. They are all kickstarted off the same config file and are kept vaguely similar to each other. The only difference I can think of is cPanel, which is only installed on the three that aren't working.

I will spin up a blank machine to test before and after installing cPanel when I get a chance.

That's good to know but I'm affraid there is something more different as
none of scripts in the log above touches perl.

Does the scripts do what they are supposed to when run manually?
Another thing -  Is selinux enabled? Are there any AVC denials in
audit.log?

The strange thing is

   Sending back response (1, 'Script failed', {'output': '', ...

because rpm -q should output something either on installed or missing key.
