I have a computer that I put Redhat 6.2 on to mess around with linux. It has 100 mhz and 40 meg of Ram. I picked a custom install and choose to install everything. But I cannot seem to get the Networking to work. It has a 3Com Etherlink III 3C509 network card and if I use the command "ifup eth0" I get a message that said ther was a delay. How can I get this working. I choose the 3Com card in the Kernal tool and added it.

Do this:

Either modify /etc/modules.conf and change the value of : alias "interface" "type"

to :

alias eth0 3c50x

or preferred way of doing this:

type linuxconf, Config, Networking, Client tasks, change the value in kernel module field to show 3c50x.

Remove the Check mark from the Adaptor Enabled check box.

Save the changes, some tasks will appear as "Status of the sytem - Commands to execute". Tab to the "Do it" tab to execute all the commands. Now, go to linuxconf againand this time, check the Adaptor status checkbox to reflect Enabled. Again tab to "Accept" and "Do it" as described above.

Exit Linuxconf

Now, in a command prompt, type
/etc/init.d/networking stop
and then type
/etc/init.d/networking start

If the above steps do not work, you will have to try the following:

a). Upgrade your linux box. RH 7.0+ versions are extremely PNP friendly with updated set of drivers.
b). In case you cannot upgrade, recompile your kernel

The delay message may be because you are looking for a dhcp server and getting no response. The file /var/log/messages has plenty of juicy debugging tidbits to help track down the problem. You might also want to run the command 'dmesg' which will give you information about the loading of modules and any errors occuring during module-loading.
If your modules load correctly, and the command 'ifconfig eth0' shows your network adapter up and running, make sure it shows an ip address. You shouldalso check out your routing table with the 'route' command. You may need to add your network and/or gateway to the routing table. Another problem I have seen is ipchains started at boot time, blocking pings and other traffic. You can see if thereare any filtering rules running with the 'iptables -L' command.
As per the previous response, you may want to just try a newer distro with easier, more automated configuration tools. That depends on whether you like to do things the easy way or the hard way. I prefer the hard way. Keeps me of the streets.

Hi,

Try to find out if the card is configured correctly wiht the ifconfig command, there you can check out the ip address and netmask. Then if all is ok, use de route command to find out the kernel routing table. Use the man command (man route) so you can choose the command flags and get some more info or better tests. Then you may correct the missconfiguration with the linuxconf command. Check out the next ?tems :
1.0.- Config
1.1.- Client tasks
1.1.1.- Basic Host configuration
1.1.1.a.- Host name : fw001.loteria.gba.gov.ar
1.1.1.b.- Adaptor 1
1.1.1.b.1.- [x] Enabled
1.1.1.b.2.- Config mode (o) manual
1.1.1.b.3.- Primary name + domain : your.linux.box
1.1.1.b.4.- Aliases :your.linux.box
1.1.1.b.5.- IP address: 10.1.1.10
1.1.1.b.6.- Netmask : 255.255.255.0
1.1.1.b.7.- Netdevice : eth0
1.1.1.b.8.- Kernel module : 3c59x (your net card kernel model)

Then the DNS configuration:

1.1.2.- Name Server Specification (DNS)
1.1.2.a.- DNS usage [x] DNS is required for normal operation
1.1.2.b.- Default name: your.linux.box
1.1.2.c.- Name server 1 : 10.1.1.10
1.1.3.- Routing & Gateways
1.1.3..- Defaults
1.1.3.a.1.- Default Gateway : 10.1.1.254
1.1.3.a.2.- Enable Routing [x]
1.1.3.b.- Routing to other networks
1.1.3.b.1.- Add network: Network 192.168.11.2 :Netmask 255.255.255.0 :Gateway 10.1.1.254
1.1.3.c.-
1.1.3.d.- The routed daemon
1.1.3.d.1.- [x] Does not export any rules
1.1.3.d.2.- [ ] Export your default route
1.1.4.- Host name seachpath
1.1.4.a.- [x] Multiple IPs for one host
1.1.4.b.- (o) host,dns

With that simple configuration you can start testing your linux.

Hope it helps ...

Good luck
