Random loss of domain name resolution!
Dear: Fellow Gnu/Linux Debian users.
I am at a loss as to solve this problem, other than to reinstall
Debian Sarge. I am using a cable connection, with DHCP enabled
getting a permannet IP address from my hardware Zyxel ZyWall router,
which allows me to set IPs according to MAC addresses. I am using
my cable companies DNS servers, other settings. As far as Debian is
concerned its DHCP but always gets the same IP address by the
router.
When I surf the internet, sometimes after about a minute of trying to
load a webpage it times out on me with a DNS resolve error. Then if
I immediately try to ping the webpage, it does not print anything to
the screen. It just sits their like its waiting for input. I have
to ctrl C to stop it. If I use traceroute on the web page, or any
web page it does the same thing.
When I switch to a different machine, I am able to get to the webpage
in question, and everything works. I am able to ping the webpage,
and traceroute the page, so I know it is a faulty Debian setup on
that one machine. Now after about two to three minutes everything
is working fine on the faulty machine. Ping works normally,
traceroute works, I am able to get to the webpage. But for the life
of me I am unable to find the problem.
I have searched my logs and have found just a few odd links like this
one for fetchmail found in syslog.
[Jun 9 07:55:34 Raiz_mpx fetchmail[12263]: POP3 connection to
pop-server.xxxx.xxxx failed: temporary name server error.]
This one is from user.log.
[Jun 8 06:51:26 Raiz_mpx xfs: ignoring font path
element /usr/lib/X11/fonts/cyri
llic/ (unreadable)]
from daemon.log I get this:
[Jun 10 09:09:21 Raiz_mpx identd[15555]: started
Jun 10 10:53:03 Raiz_mpx identd[15633]: started
Jun 10 11:03:25 Raiz_mpx identd[15644]: started
Jun 10 11:50:09 Raiz_mpx identd[15699]: started]
I have no clue if this is normal or not, it could explain the
outages. identd could be restarting when I am trying to access the
internet, but google is lacking on this mater.
I have used aptitude to look for broken packages, or packages that
are misconfigured. So far everything I have tried has not solved my
problem. This machine has been updated a few times, from a 2.4
kernel, to a 2.6 kernel. If I go back to a 2.4 kernel it still has
the same problem. I would like to solve this problem, or do I have
to reinstall from scratch. Everything else seems to work fine, I am
using a ext3 journaled file system, nothing has jumped out as being
broken other than this.
Thanks;
Rthoreau
