Hi,
This is a problem that touches some of Fedora services.
I've got a network
192.168.101.0
192.168.101.1 - this is my router
192.168.101.200 - ozzy - my F11 server
192.168.101.100 - dio - my Windows 6 workstation
I use two DNS servers
nameserver 192.168.1.1
nameserver 194.204.159.1
The problem shows up when my network 192.168.101.0 lose a connection
with 192.168.1.0 and my primary DNS server is not available.
Every time when I try to use samba I get no response from ozzy. Here
is what is happening for mc
connect(3, {sa_family=AF_INET, sin_port=htons(53),
sin_addr=inet_addr("192.168.1.1")}, 28) = 0
poll([{fd=3, events=POLLOUT}], 1, 0) = 1 ([{fd=3, revents=POLLOUT}])
sendto(3, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25,
MSG_NOSIGNAL, NULL, 0) = 25
poll([{fd=3, events=POLLIN}], 1, 5000) = 0 (Timeout)
socket(PF_INET, 0x802 /* SOCK_??? */, IPPROTO_IP) = 4
connect(4, {sa_family=AF_INET, sin_port=htons(53),
sin_addr=inet_addr("194.204.159.1")}, 28) = 0
poll([{fd=4, events=POLLOUT}], 1, 0) = 1 ([{fd=4, revents=POLLOUT}])
sendto(4, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25,
MSG_NOSIGNAL, NULL, 0) = 25
poll([{fd=4, events=POLLIN}], 1, 5000) = 0 (Timeout)
poll([{fd=3, events=POLLOUT}], 1, 0) = 1 ([{fd=3, revents=POLLOUT}])
sendto(3, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25,
MSG_NOSIGNAL, NULL, 0) = 25
poll([{fd=3, events=POLLIN}], 1, 5000) = 0 (Timeout)
poll([{fd=4, events=POLLOUT}], 1, 0) = 1 ([{fd=4, revents=POLLOUT}])
sendto(4, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25,
MSG_NOSIGNAL, NULL, 0) = 25
poll([{fd=4, events=POLLIN}], 1, 5000^C <unfinished ...>
Program tries to reach an unreachable server. I have found a
workaround - temporary comment all nameservers in resolv.conf. But
it's not a solution for a long term.
Another instance of this problem is ssh logging
- I enter an user name
- about a 60 second delay
- password prompt appear
Yet another problem (when name servers are commented out in resolv.conf)
[root@ozzy ~]# yum --enablerepo=updates-testing upgrade

I think that such behavior is clearly wrong. But it's a long term
issue. So maybe I'm wrong and this is a correct behavior?
