hostname lookups fail

Post by Thunderstone »



I am using webinator to create an index of 33 web servers on the
Columbia campus. I ran this job successfully last month, but now gw
fails to find 12 of those hosts. I ran the gw indexing job again
today, and it is failing on those same 12 hostnames. It finds the
other 21 hosts without any trouble. Ping and telnet find those hosts
without any problems, from the same machine, in less than a second.

Here is a partial list of error messages from the indexing job:

..

gw just uses the "gethostbyname" system call. The system is returning
an error condition, but apparently not setting the reason code.
Perhaps something changed in your name server config?
Does "nslookup convex.hhmi.columbia.edu" return the right info?
