Secure Computing SG300 User Manual page 67

Custom (advanced users only) allows you to enter a custom console command to run
to determine whether the connection is up. This is typically a script you have written
and uploaded to the SG unit.
Always Up means no test is performed, and Internet failover is disabled for this
connection.
If you wish, you may fine tune the timeouts for the failover test, however the defaults are
usually suitable.
Test Delay is the number of seconds to wait after starting this connection before
testing whether it is functioning correctly, a longer delay is used for connection types
that are slow to establish, such as dialout.
Retry Delay is the number of seconds to wait after a connection test fails before re-
attempting the test.
Times to attempt this connection is the number of times to try a connection before
giving up. Once the SG unit has given up trying this connection, manual intervention
is required to re-establish it.
Click Next to configure settings specific to the Test Type.
If you selected a Test Type of Always Up, no further configuration is required. Skip
ahead to Modify failover levels (primary, secondary, tertiary).
If you selected Custom, enter the custom Test Command that is used to test the
connection, e.g.: myscript 5 10 ping -c 1 -I $if_netdev 15.1.2.3
Note
If the Test Command exits with a return code of zero (0), the test is deemed to have
passed and the connection is considered up. Otherwise, the connection is considered
down. Also note that $if_netdev is replaced with the name of the network interface
on which the test is being run, e.g. ppp0.
If you selected Ping, enter an IP Address to Ping. Ensure you choose a host on the
Internet that can be contacted reliably and responds to pings. You can check whether
you can ping a host under Diagnostics -> Network Tests -> Ping Test.
