Additional Network Card (Token Ring)
HOWTO for E-SMITH 4.1.X

Purpose:

• This is to add a third or forth network interface to an E-smith Server.

• I wanted to have my E-smith Server bridge an internal Ethernet and an Internal Token Ring Network to an outside Internet Connection.

• eth0 - 3com 10/100 PCI card (Internal Net)
• eth1 - Realtec 1839 10/100 PCI card (External Internet connections)
• eth2 - 3com 10/100 PCI card (2nd Internal Net Card)
• tr0 - Madge Token Ring PCI card (Internal Net)

1. Load E-smith 4.1.X on your machine and configure the first 2 network adapters. Test machine to verify the first two are working.
2. Verify the module your network card needs is in /lib/modules/2.2.16-22/net Directory. If not, find the module on the internet and copy it to this directory.
   Notes:
   • Directory 2.2.16-22 is named after the RedHat kernal version that E-smith is compiled on. If you are using a Different version of E-smith than 4.1.2, then this directory may have a slightly different name
   • My Madge Token Ring Module wasn't. I had to compile it on a RedHat 7.0 machine and then copy it to this directory).
3. Create the custom template directory for /etc/modules.conf
   mkdir /etc/e-smith/templates-custom/etc/modules.conf
   cp /etc/e-smith/templates/etc/modules.conf/* /etc/e-smith/templates-custom/etc/modules.conf
   
4. Create a file for the additional network cards. Start the name with the number 11 or 12, so it is built after the file 10EthernetDrivers. This file will add a line to /etc/modules.conf which will link the driver module to the network interface. My madge token ring module is "mtok" and my network interface was "tr0". My second ethernet card was a 3c590 and used the module "3c59x". You might want to use pico to create these files.
   • create /etc/e-smith/templates-custom/etc/modules.conf/11tr0
     having the following lines:

              {   
              push @lines, "alias tr0 mtok"    
              }   
     

   • create /etc/e-smith/templates-custom/etc/modules.conf/11eth2
     having the following lines:

              {   
              push @lines, "alias eth2 3c59x"    
              }  
     

5. Expand the template:
   /sbin/e-smith/expand-template /etc/modules.conf
6. Create a config file for each new interface in /etc/sysconfig/network-scripts (The Name of these config files must have the device name in them)
   • Use the eth0 device config file as a template for the new devices.
     cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth2
     cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-tr0
   • edit the config files to include the ip-numbers and netmasks of the additional networks.
     pico /etc/sysconfig/network-scripts/ifcfg-eth2
     pico /etc/sysconfig/network-scripts/ifcfg-tr0
7. Start the interface: (this will happen automatically on reboot, but do it now to save rebooting)
   
   • /etc/sysconfig/network-scripts/ifup tr0
   • /etc/sysconfig/network-scripts/ifup eth2
8. Check status of Interfaces:
   • ifconfig tr0
   • ifconfig eth2
9. Check the log file for any error messages
   /var/log/messages
10. Give the Network "local network" rights with the e-smith web manager.
