domain and 2x nameservers , nothing special is defined
From memory this bug was confirmed and fixed, but, if my summary proves
correct, was back in ... March 2007
ndots appears to be where the bug is, since nothing is defined, it
should 1, so it should have seen, in our example, www.undernet.org, as
www.undernet.org and nothing more, and returned REFUSED, not carried on.
" The default value is that defined using the ndots statement
in /etc/resolv.conf,
or 1 if no ndots statement is present. Names with fewer dots are
interpreted as relative
names and will be searched for in the domains listed in the
search or domain directive in
/etc/resolv.conf.
"
proving the point...
~$ host -v -N1 www.undernet.org ns1.ausics.net
Trying "www.undernet.org"
Received 34 bytes from 62.113.243.167#53 in 365 ms
Trying "www.undernet.org.ausics.net"
Using domain server:
Name: ns1.ausics.net
Address: 62.113.243.167#53
Aliases:
Host www.undernet.org not found: 3(NXDOMAIN)
(even -N0 reports same as above)
