To close all connections with the source interface
If3
:
gw-world:/> conn -close -srciface=If3
The -verbose Option
When the
-verbose
option is used, the
connections
command adds another line of output for each
connection that is prefixed with
...term:
. This line shows the changes, if any, made by
NetDefendOS in the interface or IP or port number as the connection traverses the firewall. For
example, consider this output showing a single connection:
gw-world:/> conn -verbose

...term: If1:192.168.96.1:39097
If3:192.168.96.82:80
262119
Here, the original connection is subject to a NAT IP rule which transforms
If1:10.4.0.16:60848
into
If1:192.168.96.1:39097
. The destination remains the same but the source IP and port has been
changed by NetDefendOS. For this example, a private IP address has been used for illustration
but
192.168.96.1
would typically be a public IP address.
A complete list of all options for the
connections
command can be found in the separate
CLI

.
2.6.5. The dconsole Command
The next step is to use the CLI command:
gw-world:/> dconsole
This can be abbreviated to:
gw-world:/> dcon
The dconsole command provides a list of important events that have occurred during
NetDefendOS operation and can help to establish the date, time and nature of events leading up
to a serious problem occurring. The output might look similar like the following:

Output from
dconsole
can include a dump of the system memory in the case of serious runtime
errors. Such a dump will look similar to the following:
