16-0 Viewing and Removing Connections
This chapter shows how to view and remove TCP connections and UDP
sessions in real- time.
What are active connections?
Active connections are TCP connections or UDP sessions which are active through the
Firewall. Each one of these connections has been validated through a stateful filter rule,
which has been added by the system administrator, or through an entry in the state table,
automatically added by Aker Firewall.
For each of these connections, the firewall keeps a lot of information in its state tables.
Some of these piece of information are especially useful to the administrator and they
can be viewed at any moment through the active connections window. This information
contains the exact hour of establishment of the connections and their idle time, that is,
the amount of time that no packets passed through them.
