Writing routes in "route" file...


Hi all;

I am using SUSE Enterprise Server 10 SP2;

When I use YaST to add default gateway to one of my interfaces, everything went well, but when I open the "route" file, I see something as:

default 192.168.1.1 - -

What is "- -"?

Thanks

An excerpt from man 5 routes
Quote:
There are 5 columns with special meaning. Write a dash "-" if you want to omit an entry for a field. If all following fields in the line are empty too, you can even omit the dash.

The first column gives the destination, written as the IP-address of a host or a network. The heading default indicates that the route is the default gateway. Do not use 0.0.0.0 for this purpose. A prefix-length can be used; e.g., 10.10.0.0/16 is valid.

The second column contains the gateway. Write here the regular IP-address of a host which routes the packets to a remote host or remote network. You can omit this information for rejecting routes.

The third column gives the netmask for a remote host or remote network behind a gateway. For the default route or if you were using a prefix-length in the first column, you can omit it.

The fourth column gives the name of the interface of the local networks (lo, eth0, eth1,isdn0, ppp0, dummy0, ...).
They are the netmask and the interface fields that have been omitted.
