Configuring DNS To enable DNS functionality on the OfficeConnect Remote 812, use the command:
enable dns
To disable DNS functionality, use the command:
disable dns
You can configure three global DNS parameters that control the operation of the
DNS proxy.
Number of Retries: the number of retry attempts when accessing a primary or secondary DNS server. The default is 1 retry.
Timeout: the amount of time to wait for request to be serviced. The default is 5 seconds.
Cache size: the number resolved names to cache. The default is 100 entries.
You can view the current DNS settings with the command:
show dns settings
You can alter the current DNS settings with the command:
set dns cache_size <size>
number_retries <number> timeout <seconds>
DNS Host Entries To add a DNS Host entry to the DNS Static Host table, use the command:
add dns host <host name> address <ip address>
To view the contents of the Static Host table, use the command:
list dns hosts
To delete a specific Host entry, use the command:
delete dns host <host name>
Managing the DNS When resolving a DNS name, the OfficeConnect Remote 812 first searches for a Proxy match in the Static Host table. If a match is not found it will perform a proxy
function. The DNS Server table contains a list of DNS Servers for specific domains. Each domain listed in the table can have up to two DNS Server addresses associated with it. The default domain has the name ‘*’.
Using PPP it is possible to learn DNS server addresses when the PPP session is established. In addition to specifying server addresses in the DNS Server table, you can specify a VC profile name that should be used to learn the addresses.
To create a DNS Server entry when specific addresses are known, use the command:
