If you have one, enter the IP address of the IP Name Service
Domain
Server's machine that will translate names to addresses. This example
Name uses "192.83.159.2":
#>set config nameserv=192.83.159.2
#>
Note that if you do not have an IP Name Service machine, you
can use the PortServer's Set Host commands to build a table
of names and their IP addresses. (See page 46.)
Network Set your network subnet mask. (The PortServer's default
setting is 255.255.255.0); that's also the mask used in this
Subnet
Mask example:
#>set config submask=255.255.255.0
#>
If you have a gateway, set its IP address. (The default setting of
Gateway
Address 255.255.255.255 is used in this example):
#>set config gateway=255.255.255.255
#>
There are other PortServer parameters that can be configured. These are covered
individually in the Command Reference chapter.
