Q: how to configure default gateways and routes to specific networks or hosts in SLES8

Q: how to configure default gateways and routes to specific networks or hosts in SLES8

A: yast network can be used in SLES8 to configure default gateways and routes to specific networks or hosts, or by modifying the

Method and run the command to achieve this goal

Method 1. Configure through yast2 management tools

Run the yast2 tool in console to select routes and add routes configured to specific networks or hosts in expert mode

# yast2 network

For configuring unconfigured network cards

"Configure..." in "Network cards configuration" in "Network cards configuration"

For modifying the settings of the configured network card

"Changev..." in "Network cards configuration" in "Network cards configuration"

"Detailed settings" in "Network address setup" Click "Routing"

Enter the default gateway in the "Default gateway" input box.

If you want to set a route to a specific network or host, select "Expert configuration" in "Routing table"

In the dialog window for "Add" and "Edit", fill in "Destination", "Dummy or Gateway" and "Netmask"

You don't have to fill in "Device".

Example 1: the gateway for the network 192.168.2.128Gateway 255.255.255.128 is 192.168.2.129

"Destination" enter the destination network address 192.168.2.128

"Dummy or Gateway" fill in the gateway address 192.168.2.129

"Netmask" fill in 255.255.255.128

Example 2: the gateway of host 192.168.3.20Universe 255.255.255.255 is 192.168.3.20

"Destination" enter the destination host address 192.168.3.20

"Dummy or Gateway" fill in the gateway address 192.168.3.20

Fill in 255.255.255.255 for "Netmask"

Method 2. Configure by modifying the configuration file and running the command

Modify the file / etc/sysconfig/network/routes to configure default gateways and routes to specific networks or hosts

Format of the file:

The lines starting with # are comments, and each line is a routing record, consisting of multiple columns separated by spaces

Example / etc/sysconfig/network/routes file

# default gw

Default 192.168.0.1--

# network 192.168.2.128/255.255.255.128 gateway set to 192.168.2.129

192.168.2.128 192.168.2.129 255.255.255.128

# host 192.168.3.20/255.255.255.255 gateway set to 192.168.3.20

192.168.3.20 192.168.3.20 255.255.255.255

This configuration file will be loaded when / etc/rc.d/network start is executed

Run the command to add the above route

# route add default gw 192.168.0.1

# route add-net 192.168.2.128 netmask 255.255.255.128 gw 192.168.2.129

# route add-host 192.168.3.20 gw 192.168.3.20

Delete the above route

# route del-net 0.0.0.0

# route del-net 192.168.2.128 netmask 255.255.255.128

# route del-host 192.168.3.20
