ERROR: 202.85.165.88: [addr 202.85.164.38: hostname lookup failed]

Dear all,   Thanks for the guide for RPM for RH7.0.   Now, it worsk for my own server's backup.   But, for the another client backup, I have added the server's entry in the .amandahosts ns31.newsbook.net operator 202.85.164.38 operator   Then, I run the following on my server:   sh-2.04$ ./amcheck DailySet1 Amanda Tape Server Host Check ----------------------------- /var/tmp: 26420536 KB disk space available, that's plenty. NOTE: skipping tape-writable test. Tape DailySet100 label ok. Server check took 0.052 seconds.   Amanda Backup Client Hosts Check -------------------------------- ERROR: 202.85.165.88: [addr 202.85.164.38: hostname lookup failed] Client check: 2 hosts checked in 0.023 seconds, 1 problem found.   (brought to you by Amanda 2.4.1p1)         And have the above problem. So, I use nslookup in my server and get:     [root@ns31 DailySet1]# nslookup *** Can't find server name for address 202.85.164.38: Non-existent host/domain *** Can't find server name for address 202.85.138.168: Non-existent host/domain *** Can't find server name for address 202.85.153.182: Non-existent host/domain *** Default servers are not available      Is it my IP setting wrong and cause the problem? How can I correct it?   Yours, Richard Ao
