Strange trouble with my network......

Mustard007

Hi !

I have a strange trouble with my network....

All working good, i reboot the computer and now no network anymore.
i have 2 card: Fisrt 3c59x and Second 8139too.

The cards is up (lsmod) and ifconfig. If i do a ping on the ip of each card on the same machine it's ok. But form other machine...nothing. I have stopped iptable (maybe a rules troubles ??) but not working too.

I use adsl-setup to acces internet.....doesn't work anymore. The card can't talk with de adsl-router.( i can't see the led on the adsl-router when i try to connect now).

So, the card seem to be up and running but no activity !!

Thanks !
P.S.( Sorry for my bad english ;o) )

Mustard007,

Please post the output of /sbin/ifconfig and /sbin/route -n
How does each network card get its setup information, the IP address etc?

Please don't withhold the IP addresses unless they are public ones, then blanking out the first group uf numbers should be adequate.

Hi !

Sorry for the delay....

So here the ouput:

Mustard007,

A couple of things,

Your routing table is missing a defaut route. The the moment it says to send packets to the 192.168.7.0 network send them to eth0. It that rule doesn't fit it tries the next one which says to send packets to the 192.168.0.0 network send them to eth1.
The last rule says to send packets to 127.0.0.0 send them to local (lo).

All other packets are thrown away, which is not what you want.
ifconfig looks good.

The last line of /etc/conf.d/net is wrong.

Mustard007,

Post the new route -n output and the IP info for your router.

Problem solved....i reinstalled Gentoo ;o)

And, i dont have to uncomment the gateway or my ADSL doesn't work anymore.

This is my route -n when the ADSL (rp-pppoe) is able to run.:
---------------
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
66.36.128.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.7.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 66.36.128.1 0.0.0.0 UG 0 0 0 ppp0
----------------

So the mysterious trouble of my network is not resolved but now it's ok with a new installation.

Thanks !!
