[rules-users] Unable to parse ChangeSet in Linux Machine

[Wolfgang Laun]

It seems that the Linux host isn't even getting the change set XML file.

Can you retrieve the file via ftp from the Linux machine without any
problems? It may be an issue of the ftp server not running, not being
known or available, or no (anonymous) file transfer being permitted
etc. etc.
