hi,

I have recently switched from a RH and XP dual boot system to a complete installation of slackware. Why? Well thats a story for another day. Anyway, I have two NICs, one for my cable modem (which works fine) and one for a cross over cable for my flat mate so he can share my internet connection. On installation Slackware picked up the cable modem NIC on eth0 and prompted me to configure it with netconfig. Once completed eth0 works fine. However, the installation did not detect the second network card. After browsing the internet for solutions I have managed to get the second NIC detected by doing the following:

Adding "alias eth1 ne" to /etc/modules.conf
Configuring the eth1 section of /etc/rc.d/rc.inet1 to include my local network IP settings in this way:

# Edit these values to set up your second Ethernet card (eth1),
# if you have one. Otherwise leave it configured to 127.0.0.1,
# or comment it out, and it will be ignored at boot.
IPADDR2="192.168.0.1" # REPLACE with YOUR IP address!
NETMASK2="255.255.255.0" # REPLACE with YOUR netmask!
# Or, uncomment the following lines to set up eth1 using DHCP:
#USE_DHCP2=yes
# If your provider requires a DHCP hostname, uncomment and edit below:
#DHCP_HOSTNAME2="CCHOSTNUM-A

following these changes I rebooted and ifconfig now shows eth1:
eth0 Link encap:Ethernet HWaddr 00:50:BF8:AE:32

now its been detected and appears to display the right settings Im not sure how to configure properly for the internet connection sharing. Ive tried to use netconfig to configure eth1 but this seems to reconfigure eth0 every time its run.

Whats the next course of action? Or is there any slackware home networking how tos or resources available? Ive used the redhat one sucessfully in the past but the instructions in this howto are not generic.

Any help would be very appreciated particularly by my housemate who is currently internet connectionless!

Cheers

I have now got my both computers on the network pinging each other and my flatmates computer obtaining its IP address from mine using dhcp. However I still cant ping my ISPs domain name servers from my flatmates computer although I can do from mine.

Whats the next step?

just fixed it with the command:

/usr/sbin/iptables -t nat -A POSTROUTING -s 192.168.1.0 -d 0/0 -j MASQUERADE

which I found on another post in this forum.

Thanks, this is a great information resource.

Nice dialog with yourself :-) This is a great forum. It is getting to the point that the most pertinent answer is often "search the archives".
