Only for the administrator users:
Typing all.escape_char or sN.escape_char from the sniff session or “send message mode”
will make the BLACK BOX ® Advanced Console Server show the previous menu. The first
regular sessions will not be allowed to return to the menu. If you kill all regular sessions using
the option 4, your session initiates as a regular session automatically.
Parameters Involved and Passed Values
Sniffing involves the following parameters:
all.admin_users This parameter determines which users can receive the sniff
menu. When users want access per port to be controlled by
administrators, this parameter is obligatory and authtype must
not be none. User groups (defined with the parameter
conf.group) can be used in combination with user names in the
parameter list. Example values: peter, john, user_group.
all.sniff_mode This parameter determines what other users connected to the
very same port (see parameter admin_users below) can see of
the session of the first connected user (main session): in shows
data written to the port, out shows data received from the port,
and i/o shows both streams. The second and later sessions are
called sniff sessions and this feature is activated whenever the
protocol parameter is set to socket_ssh or socket_server.
Example value: out.
all.escape_char This parameter determines which character must be typed to
make the session enter menu mode. The possible values are
<CTRL-a> to <CTRL-z>. Represent the CTRL with carat: ^. This
parameter is only valid when the port protocol is socket_server
or socket_ssh. Default value is ^z.
