[Bug 504963] Re: [Karmic] host -4 does IPv6 lookup -- times out
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 (used by Orange, 12 million broadband internet customers in Europe). Looks like I'm one of the lucky 12 million :) -- [Karmic] host -4 does IPv6 lookup -- times out https://bugs.launchpad.net/bugs/504963 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bind9 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 504963] Re: [Karmic] host -4 does IPv6 lookup -- times out
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 www.google.com. In each case, the 'before_wait' file is the log up to the moment that the program gets temporarily stuck; it waits about half a second and then later once or twice more. Each time just after printing: unlock_lookup dighost.c:2145 the full log is in the *all.log files. Hope this is useful. Let me know if you need more info.

I am not able to reproduce this at all. I think you may have problems with your dns server. chuck ** Changed in: bind9 (Ubuntu) Importance: Undecided = Low ** Changed in: bind9 (Ubuntu) Status: New = Incomplete -- [Karmic] host -4 does IPv6 lookup -- times out https://bugs.launchpad.net/bugs/504963 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bind9 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
Re: [Bug 504963] Re: [Karmic] host -4 does IPv6 lookup -- times out
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. Marco.

I some posts, I found that ip -6 route may provide useful info.
