My first post here and i would like to thank to all the developers for
their terrific work.
Now, my problem. Short story: kernel 2.4.24, vserver 1.26 (no other
patches). bind9 with nocapset (Paul Sladen's debian packages), running
inside a vserver. doesn't answer to udp requests, but works with tcp
requests.
short question: does anyone using bind9 inside vserver with recent series of
patches (it worked for me with old Jacques Gélinas's ctx patches).
long story (aka bugreport).
- debian, kernel 2.4.24-vs1.26
- bind packages
bind9 9.2.1-2.woody.1.nocapset
bind9-host 9.2.1-2.woody.1.nocapset
dnsutils 9.2.1-2.woody.1.nocapset
libbind-dev 9.2.1-2.woody.1.nocapset
libdns5 9.2.1-2.woody.1.nocapset
libisc4 9.2.1-2.woody.1.nocapset
libisccc0 9.2.1-2.woody.1.nocapset
libisccfg0 9.2.1-2.woody.1.nocapset
liblwres1 9.2.1-2.woody.1.nocapset
- bind9 is running ans listening on port 53 both udp and tcp (checked with
netstat)
- bind9 is answering to tcp requests (tested with 'host -T' and
netcat, both from local and remote)
- on udp requests it just hangs (tested with 'host ' command and netcat -u)
- other daemons on udp works (tested with netcat -l -u)
- tcpdump -n -i eth0:VSERVER src or dst port 53
* 'host localhost' name server request
tcpdump for port 53, normal name server request gives something like
11:58:25.623806 SRC_IP.35401 > DEST_IP.53: 52567+ A? localhost.TLD. (43) (DF)
(repeated twice, after which, i get
";; connection timed out; no servers could be reached")
* 'host -T localhost' name server (tcp) request
a full page of tcp dumped conversation, after i get the normal response
One solution, suggested last night by Herbert on irc, would be to try a
development release. Maybe i'll do it, in the meanwhile, do you have any
other ideeas or success stories with bind9 inside vserver?
