RE: Local address lookup

[Jan Willem Stumpel <jstumpel@planet.nl>]

I seem to have a DNS problem indeed. When I run tcpdump in an X
window on jupiter and call

    telnet saturn

in another window, I get a lot of packets beginning with

    19:35:30.080780 jupiter.my.home.1024 > ns1.myisp.nl.domain:
       19522+ AAAA? saturn. (23)
    19:35:30.081839 jupiter.my.home.1025 > ns1.myisp.nl.domain:
       17118+ PTR? 34.1.121.195.in-addr.arpa. (43)
    19:35:30.107275 ns1.myisp.nl.domain > jupiter.my.home.1024:
       19522 NXDomain 0/1/0 (98) (DF)

So a private telnet to an entirely local computer involves my
ISP's name server (ns1.myisp.nl), i.e. the outside world. I do not
like this at all. It is in fact pretty frightening. I had supposed 
that "order hosts,bind" in /etc/host.conf would keep local address 
lookups local, but apparently it does not.

Maybe there is some connection with xinetd as Nate suggested. In 
the past I had an xinetd directly from xinetd.org, not "linked 
with libwrap". Now I have a stock Woody xinetd. And I am pretty 
certain (but cannot prove it of course) that my telnet delay 
problem is fairly recent. Am going to experiment (with compiling 
xinetd from source, without libwrap), will report .. BTW, (in 
response to Mike Kuhar), in nsswitch.conf I had the proper order 
(hosts: files dns) all along.
