IBM Lotus Domino 6.5 for Linux on Zseries Implementation

5.3 Linux networking

A Linux guest can be installed, with the primary network interface being a guest LAN.

5.3.1 Connecting Linux to a z/VM guest LAN

If a guest LAN is defined and the z/VM Linux guests have a NIC defined and coupled (see 5.2.3, "Add network interface cards (NICs) to Linux user IDs" on page 76), a network interface to a Linux guest can be added as follows.

1. Update the file /etc/chandev.conf to define the device.

2. Update the file /etc/modules.conf to associate a driver to an interface.

3. Create a configuration file in the directory /etc/sysconfig/network/, as shown:

   # cd /etc # tail -1 chandev.conf noauto;hsi0,0x0600,0x0601,0x0602;add_parms,0x10,0x0600,0x0602,portname:GESTLAN1 # tail -1 modules.conf alias hsi0 qeth # cd sysconfig/network/ # cat ifcfg-hsi0 BOOTPROTO="static" STARTMODE="onboot" IPADDR="10.0.0.1" MTU="1500" NETMASK="255.255.255.0" NETWORK="255.255.254.0" BROADCAST="255.255.254.0"

Figure 5-3 on page 80 illustrates possible Domino, Linux, and VM configurations that might be considered, depending on your environment.
