RussianQuestion
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.
I can browse the target server to create a selection list, and when I do a test run it completes successfully.
However, when I run a real backup, the job fails immediately during the "processing" phase with the error:
e000fe30 - A communications failure has occured.
I've tried opening ports (10000, 1025-9999), etc. But no joy. Any ideas?
Solution
Sure sounds like firewall issues. Try stopping iptables, and running again. Also, RALUS can dump a log file - which may give some more to go on.
I use the older UNIX agent myself, which uses port 6101 IIRC - but I believe that the newer client uses tcp/10000 for control and 1024-65535 for transfer.
Last resort is to fire up a network sniffer. ;)
OTHER TIPS
To clarify the answer, the solution was to open up the tcp ports from 1024-65535.
The iptables looked liked this:
[root@MYSERVER ~]# service iptables status
Table: filter
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0

I executed this command to add the new rule:
[root@MYSERVER ~]# iptables -I RH-Firewall-1-INPUT 14 -p tcp -m tcp --dport 1024:65535 -j ACCEPT
Then they looked like this:
[root@MYSERVER ~]# service iptables status
Table: filter
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0

Save the iptables when you've verified that it works:
[root@MYSERVER ~]# service iptables save
