IP Name Resolving
6-7
To use the DNS, the SCS must know the IP address of the DNS server.
6.3.1 Configuring the Domain Name Service (DNS)
To use the DNS for name resolution, use the Set/Define IP Nameserver command.
Figure 6-13: Setting the Domain Name Server
To specify a backup nameserver, use the Set/Define IP Secondary Nameserver command. If the first
nameserver isn’t available, the request will be sent to the secondary server.
6.3.2 Specifying a Default Domain Name
A default domain name may be configured using the Set/Define IP Domain command. This domain name
will be automatically appended to any host name during name resolution.
Figure 6-14: Configuring a Default Domain Name
In the example above, the default domain name is ctcorp.com. If user Bob typed telnet athena, the SCS
would automatically append the domain suffix and attempt to resolve athena.ctcorp.com.
If a hostname is entered that ends with a period (“.”), the SCS will not add the domain suffix to the hostname
for resolution.
6.3.3 Adding Hosts to the Host Table
If DNS is not available on your network, hosts may be manually entered in the local host table using the
Set/Define Hosts command.
Figure 6-15: Adding a Host to the Local Host Table
To display the current entries in the host table, use the Show Hosts command.
Figure 6-16: Displaying Host Table Entries
To remove an entry from the host table, use the Clear/Purge Hosts command.
