Hello. I'm seeing an odd telnet problem on 4.1-RC. I track RELENG_4
and just updated my machine (pinhead) from a source checkout and build
from 14-15th (Friday-Saturday) including installkernel and mergemaster.
All hostname lookups are failing from telnet, but only from telnet and
only hostnames. Here's the problem:
$ telnet localhost
localhost: No address associated with hostname
$ nslookup localhost
Server: localhost.parag.codegen.com
Address: 127.0.0.1
Name: localhost.parag.codegen.com
Address: 127.0.0.1
$ ping -c 1 localhost
PING localhost.parag.codegen.com (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0.167 ms
--- localhost.parag.codegen.com ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.167/0.167/0.167/0.000 ms
$ telnet 127.0.0.1
Trying 127.0.0.1...
Connected to localhost.parag.codegen.com.
Escape character is '^]'.
login: ^D
Connection closed by foreign host.
$
ftp/ssh/etc all work fine with the same hostnames. telnet works with an
IP address but fails to lookup *any* hostname - local or otherwise - so
it doesn't seem to be a telnetd problem. ftp works fine to localhost.
I just now updated my copy of the CVS tree and updated /usr/src but
nothing in the usr.bin/telnet directory has been updated. I can't spot
anything obvious in the CVS logs either.
Anyone have any ideas I can try out to figure out what's going on?
(Odds are I've forgotten something.) Thanks in advance.
