George: See if someone in your Network team changed anything in your firewall that would affect timeouts for UDP traffic. It appears to me that the amandad is not seeing the messages in time and timing out. Someone may have shortened a timeout value in the firewall or fat-fingered a setting that affects your connection.
You may have already checked these items; if so, sorry to duplicate your efforts, otherwise, look at network changes that occur between the two servers. Best wishes, Donald L.

The strange thing is this worked for over a year and suddenly started failing. It does not appear to be an acl or firewall issues, because sometimes it will work. I set up a separate config just for this host so I could test, and find that I can kick of amdump, it appears to start on the client (I get the debug files), but at some point it dies and I get an amandad debug with the following that the end: amandad: time 126.413: dgram_recv: timeout after 10 seconds amandad: time 126.413: waiting for ack: timeout, retrying amandad: time 136.413: dgram_recv: timeout after 10 seconds amandad: time 136.413: waiting for ack: timeout, retrying amandad: time 146.413: dgram_recv: timeout after 10 seconds amandad: time 146.413: waiting for ack: timeout, retrying amandad: time 156.413: dgram_recv: timeout after 10 seconds amandad: time 156.413: waiting for ack: timeout, retrying amandad: time 166.413: dgram_recv: timeout after 10 seconds amandad: time 166.413: waiting for ack: timeout, giving up! amandad: time 166.413: pid 6926 finish time Wed Sep 22 10:04:29 2004 If I stop the processes on the server, and run amcleanup, and restart amdump, with _no_ changes to anything, the dump will complete normally, most of the time. Other times it will fail with the same type of output in the debug file and I'll have to repeat. The client and server are running linux, (debian testing) amanda 2.4.4.p3. Needless to say, the intermittancy of this making troubleshooting difficult. The clients on the same subnet as the server back up normally. -- George Kelbley System Support Group Computer Science Department University of New Mexico 505-277-6502 Fax: 505-277-6927 ************************************************************************ This e-mail and any of its attachments may contain Exelon Corporation proprietary information, which is privileged, confidential, or subject to copyright belonging to the Exelon Corporation family of Companies.
