Hi ! This is kind of follow-up to an earlier message "name resolving doesn't work", but now I can provide a bit more info...
I have a big problem with the name resolving in my tiny network: One of my computers (debian, woody with no update since ages, named "marvin", ip 192.168.42.99 ) connects via dial up (analog modem) to the internet. On this computer, everything works fine. All the following test were made with marvin "on-line" Until yesterday, everything worked fine. I did not change anything on marvin. But now, on both of my linux-boxes (eddie and zaphod) name resolving doesn't work anymore, maybe because I can't access the nameserver on marvin (?)... Eddie: # cat /etc/resolv.conf search galaxy.home domain galaxy.home nameserver 192.168.42.99 [EMAIL PROTECTED]: > ping www.fhm.edu ping: unknown host www.fhm.edu [EMAIL PROTECTED]: > ping 129.187.244.84 PING 129.187.244.84 (129.187.244.84): 56 data bytes 64 bytes from 129.187.244.84: icmp_seq=0 ttl=251 time=181.3 ms 64 bytes from 129.187.244.84: icmp_seq=1 ttl=251 time=164.4 ms I can telnet to the nameserver port on marvin from marvin: Marvin: # telnet localhost 53 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. This works from everywhere in the net, but it takes a long time until the Telnet promt comes up from eddie or zaphod. The named logfile on marvin does not complain about anything but shows: Jan 29 18:28:44 Marvin named[7989]: USAGE 1012325324 1012323707 CPU=0.1u/0.05s CHILDCPU Jan 29 18:28:44 Marvin named[7989]: NSTATS 1012325324 1012323707 A=12 PTR=14 Jan 29 18:28:44 Marvin named[7989]: XSTATS 1012325324 1012323707 RR=0 RNXD=0 RFwdR=0 RD Jan 29 18:28:44 Marvin named[8484]: starting (/etc/bind/named.conf). named 8.2.4-REL-N Jan 29 18:28:44 Marvin named[8484]: hint zone "" (IN) loaded (serial 0) Jan 29 18:28:44 Marvin named[8484]: master zone "localhost" (IN) loaded (serial 1) Jan 29 18:28:44 Marvin named[8484]: master zone "127.in-addr.arpa" (IN) loaded (serial Jan 29 18:28:44 Marvin named[8484]: master zone "0.in-addr.arpa" (IN) loaded (serial 1) Jan 29 18:28:44 Marvin named[8484]: master zone "255.in-addr.arpa" (IN) loaded (serial Jan 29 18:28:44 Marvin named[8484]: listening on [127.0.0.1].53 (lo) Jan 29 18:28:44 Marvin named[8484]: listening on [192.168.42.99].53 (eth0) Jan 29 18:28:44 Marvin named[8484]: listening on [129.187.31.161].53 (ppp0) Jan 29 18:28:44 Marvin named[8484]: Forwarding source address is [0.0.0.0].1038 Jan 29 18:28:44 Marvin named[8485]: Ready to answer queries. I never set up bind, just used pppconfig on marvin to set "static" dns and made the resolv.conf file mentioned above on eddie.
