Hello everybody.I am a newbie with linux and seeking for help.(BTW sorry for poor english)

Well i have a box with slack and a box with debian and tried to make a local network.

At 1st i have slackware and configured with netconfig.The 1st is the gateway.
At 2cd on i have debian.And configured with netconf.

My main problem is that the boxes don't see each other with ping.So there is no connection.Below are some infos:


Both NICs are recognized but i see some differences at dmesg|grep eth0

1st NIC (hostname.domain amd64.gabriel.gr)
eth0: RealTek RTL8139 at 0xa000, 00:80:48:34:15:98, IRQ 17

Any suggestion will be welcome.Thanks in advance.

Hello there again.

I could find any infos about my problem yet.Could somebody tell me how can i force to link up my eth0 ?

Ok , everything is fine apart i have to define the iptables rules.

I had a bad RJ45 cross cable.I've changed it and now i can ping each other

Best Regards
