Re: routing table problem after power failure (sarge)

I wrote my comment between the lines, like Jan.

Ah, ok. Understood. So the router is out of my calculations. Remains your
routing table at altijd.

Looks perfectly.

Also. Crazy that it doesn't recognize "localhost".
I disabled eth1 in /etc/network/interfaces and rebooted. Now pinging localhost is ok.

Yep, ifconfig showed about 200Megs for eth0 and about 140Kilos for eth1,
IIRC (without scrolling up the archive). Hm, currently reading some sites
about "problems with asymmetric routing". All in all very interesting, but not
explaining the problems you have.

No, I don't think that will alter the situation.
Me too.

Hey, we're not at a Windows box here... ;-) "Ah, TCP/IP doesn't work, oh well,
deinstall, reinstall, reconfigure until it works... *lalala*
(no offense or OS flame war intended, note the smiley)
I've never had to de-&re-install something on Debian up to this day...
Allright, I'm using windows for about 8 years, and linux for about 1/2 year....... Now I know how these things should go.

Hmm, just out of curiosity, remove one of the interfaces from the "auto"
lines in /etc/network/interfaces, and reboot (so we get a fresh state).
Would be interesting if your net is available then. Maybe it's the duplicate
route that's causing problems (although then there should also be problems
when pinging on the LAN etc.).

> Samba still not working.  I'll report after Win2k reboot, tomorrow.
> Restarting switch did not help.
Hmm no, after reading your description above I'm pretty convinced that the
problem is somewhere in the configuration depths of the Debian box.
Samba is now working! (one NIC disabled)

But after reboot, that f**king /etc/resolv.conf is again empty! That means:
- I can ping to an ip on the internet
- I can't resolv any name with my ISP's nameservers.
- when I write back my nameservers in /etc/resolv.conf, I can do nslookups and ping to names.

What package does wipe this file at boot? Maybe the resolvconf package has to do something with it. I don't know anything about this package, but it has to do something with bind and dhcp, which I don't use. It is not installed, but an /etc/resolvconf/ dir is existing.

I discovered something which may be strange:
in /etc/network/interfaces:
"lo" is mentioned on the "auto" line
but there is no configuration for lo, like exists for eth0 and eth1.

Do I need to post that file, or post ifconfig agian?

> Hope you're happy the problem was this stupid....
Oh, it's still there, isn't it? But you're right, we'll jump at it tomorrow.

> Corné
Good night!


PS: If some networking expert wants to jump in and lend a hand, please feel
free to - route & co. isn't one of my specialties... ;-
We would all be very pleased with that :-)

Anyway, thx everybody for response.
