dmesg now has the following lines:
3c59x: Donald Becker and others...
00:08.0: 3COM PCI 3C905c Tornado at 0xe400 Vers LK1.1.18

ifconfig confirms that the eth0 interface is up!

However, I do not see an eth0 device in /dev, i.e. no /dev/eth0

This very same card was working fine in the same exact hardware configuration with 10.2.

Does anyone have a bit of insight to share? :)

Thanks!

Hi,

The eth device is a logical network interface and handled differently. As far as the kernel is concerned this network interface is a software object. You could use google-linux to get some really good information.

You do seem to have the eth0 device up. Did you run netconfig?
Or edit the /etc/rc.d/rc.inet1.conf file? I like to start with a static IP for most installs, then if the person(s) wants dhcp the configure of the /etc/rc.d/inet1.conf will be adjusted.

If you make a change to eth0 in /etc/rc.d/rc.inet1.conf file, you must restart the inet as root.

Code:

#/etc/rc.d/rc.inet1 restart #restart network

If you manually setup the eth0 device then you will need to as root;

Code:

#ifconfig eth0 192.168.0.15          #state IP

#route add default gw 192.168.0.1    #set gateway

#route -n                            #will show route table

#ping 192.168.0.1                    #your gateway

#ping 64.233.161.104                #google IP outside LAN

#ping google.com                    #check DNS

If the ping google.com fails then check the /etc/resolv.conf file for your DNS.

Remember that the above is just a manual configuration. If you reboot the setting will be lost unless you insert the information into the /etc/rc.d/rc.inet1.conf.
