[Spacewalk-list] Spacewalk 2.2 clients - remote commands fail on some systems

[Ryan Clough]

All,

I have 7 systems which will not complete a remote command no matter how
simple. I believe that the problem lies in the construction of the XML.
Here is how I found the difference in the systems output.

1.  In order to remove osad from the picture, I stopped the daemon on a
system that does not complete the remote command and one that does.

2. Using SSM I send the same remote command to both systems, "ls /". A
simple "ls" on the root mount.

3. Now call "rhn_check -v -v -v -v -v -v -v" on both systems and capture
the output.

4. Compare output.

Now the interesting lines are the XML lines and the "do_call" line. The
"do_call" line is much easier to see so I will show it here.

Working system "do_call" line:
D: do_call script.run(4107, {'username': 'root', 'groupname': 'root',
'now': '2014-09-16 23:18:23', 'timeout': 600, 'script': '#!/bin/sh\n# Add
your shell script below\nls /'}){'cache_only': None}

Nonworking system "do_call" line:
D: do_call script.run(4106, {'username': 'root', 'groupname': 'root',
'now': '2014-09-16 23:15:44', 'timeout': 600, 'script': '#!/bin/sh\r\n# Add
your shell script below\r\nls /'}){'cache_only': None}

As you will notice the line separators are different and it is my opinion
that the "\r" has something to do with this failure. Any ideas about how to
find and fix this issue would be much appreciated. Let me know if you would
like additional information about my setup.

Here is some additional information about the two systems:

# cat /etc/issue
Scientific Linux release 6.5 (Carbon)
# python --version
Python 2.6.6
