<p>I'm trying to do a file system backup of a RedHat Enterprise Linux v4 server using Symantec Backup Exec 11d (Rev 7170).  The backup server is Windows Server 2003.</p>

<p>I can browse the target server to create a selection list, and when I do a test run it completes successfully.</p>

<p>However, when I run a real backup, the job fails immediately during the "processing" phase with the error: </p>

<p><em>e000fe30 - A communications failure has occured.</em></p>

<p>I've tried opening ports (10000, 1025-9999), etc. But no joy.  Any ideas?</p>

Try stopping iptables, and running again. Also, RALUS can dump a log file - which may give some more to go on. </p>\n\n<p>I use the older UNIX agent myself, which uses port 6101 IIRC - but I believe that the newer client uses tcp/10000 for
