I had an amanda setup that worked fine until two weeks ago, when I had to change the network addresses of all my hosts and move them into a separate DMZ, using a different, new DNS. Now, I'm not able to get one host to respond, and the output is puzzling:
[EMAIL PROTECTED]:/tmp/amanda-dbg$ amcheck -c DBackup Amanda Backup Client Hosts Check -------------------------------- ERROR: www.jhuccp.org: [addr 10.253.192.205: hostname lookup failed] Client check: 2 hosts checked in 0.702 seconds, 1 problem found (brought to you by Amanda 2.4.4p3) [EMAIL PROTECTED]:/tmp/amanda-dbg$ dig www.jhuccp.org ; <<>> DiG 9.2.4 <<>> www.jhuccp.org ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 41347 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.jhuccp.org.

The IP address that amcheck responded with, 10.253.192.205, is the IP for the tapehost itself, cn2. Is amcheck complaining that 10.253.192.204 doesn't resolve to www.jhuccp.org (it shouldn't; www.jhuccp.org is 205), or is it complaining that 10.253.192.205 doesn't resolve correctly to the name of the tapehost? I tried to check the debug files generated in /tmp/amanda-dbg/. There were four files generated from 'amcheck -c DBackup', but none of them seemed to contain any information regarding this failure. Thanks for any suggestions or advice in working on this problem. -Kevin Zembower ----- E.
