Configuring Global Settings 2-3
Setting the Telnet Port
Setting the Name Server
The PortMaster supports RFC 1877, which allows remote hosts also supporting
RFC 1877 to learn a name server through PPP negotiation. You must provide the IP
address of the name server if you use a name service.
You must set a name service before you set a name server. See “Setting the Name
Service.” If you are not using a name service, you do not need a name server.
To set the name server, use the following command:
Command> set nameserver Ipaddress
You can set an alternate name server with the following command:
Command> set nameserver 2 Ipaddress
You must set a domain name for your network after you set a name server. See “Setting
the Domain Name.”
You can disable the use of a name service by setting the name server’s IP address to
0.0.0.0.
Setting the Domain Name
The domain name is used for hostname resolution. If you are using DNS or NIS, you
must set a domain name for your network.
To set the domain name of your network, use the following command:
Command> set domain String
Setting the Telnet Port
The Telnet access port can be set to any number between 0 and 65535. The Telnet port
enables you to access and maintain the PortMaster using a Telnet connection to this TCP
port. If 0 (zero) is used, Telnet administration is disabled. The default value is 23. Ports
numbered 10000 through 10100 are reserved and should not be used for this function.
Up to four administrative Telnet sessions at a time can be active.
To set the Telnet access port to port number Tport, use the following command:
Command> set telnet Tport
Using the Telnet Port as a Console Port
If the console port is set from a Telnet session, the current connection becomes the
console. This feature is useful for administrators who log in to a port using Telnet and
need to access the console for debugging purposes.
Note – Only one Telnet session can receive console messages at a time.
