Public bug reported:
Binary package hint: bind9
When using 'host' to do a dns lookup on Karmic, I get a fast initial
response for the IPv4 lookup:
m...@purple:~$ host www.google.com
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 74.125.77.99
www.l.google.com has ad
I some posts, I found that ip -6 route may provide useful info. Here is
the output:

and a different network. The o
Yes, the DNS server in my DSL modem does not support IPv6 (A requests
?). I am wondering why 'host' does a IPv6 (AA) lookup after receiving a
valid response on IPv4 (AAA request).
I try looking into the debug printouts, but did not learn much. I can post
the debug-output if it is helpful.
Hi Chuck,
Attached the debug printout from host -D. The first two files
host_before_wait.log and host_all.log are from just running 'host -D
www.google.com, while the file host_minus4*.log are from running host -D -4

A similar issue is discussed here:
https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/417757
but I think that's about a different DNS resolver. E.g. in Firefox you
can switch off ipv6 lookups and the delay is gone. Also note the comment
in that thread:
The 5 second lag occurs with the Livebox
I've also exprienced this problem, although for a different reason. The problem
seems to have been fixed in recent versions (3.3.x) of samba. See:

I tested removing dangling symlinks using Ubuntu 8.10 (Intrepid Ibex) as
a server and that seems to wo

when lookup up a host with the 'host command' there is a long wait after
the initial response. This seems to be related to second round of

And the output of lddd `which host`. Maybe you can compare the library
versions to ones on your computer?
m...@purple:~$ ldd `which host`
linux-gate.so.1 => (0x00e47000)
liblwres.so.50 => /usr/lib/liblwres.so.50 (0x00fa2000)
libdns.so.50 => /usr/lib/libdns.so.50 (0x0062000
Do you maybe have any further suggestions for how to debug this?
Something must be interfering with those lookups. The effect is new in
Karmic, so would be nice to figure out what it is.
What is the difference between the first lookup that 'host' does and the
second?
It seems that something is b
