135Appendix E Multiple Sniffing
Cyclades-TS Installation & Service Manual
Versions 1.3.3 and later
Users will be able to open more than one common and sniff sessions at the same port. For this purpose, the
following configuration items will be included in the file pslave.conf:
• all.multiple_sessions: valid for all the serial ports; must be “yes” or “no”. The default value is “no”.
• sN.multiple_sessions: valid only for port N; must be “yes” or “no”. If it is not defined, it will assume the value
of all.multiple_sessions.
• all.escape_char: valid for all the serial ports; this parameter will be used to present the menus below to the
user. Only characters from ‘^a’ to ‘^z’ (i.e. CTRL-A to CTRL-Z) will be accepted. If this parameter is not set in
pslave.conf, or in case it contains an invalid value, regular sessions will not be allowed to return to the menu
regardless to what is typed by the user, whereas sniffer sessions will present the menu only if users type
<CTRL-Z>. In addition, regular sessions will only be allowed to see the menu if the protocol used is
“socket_server” or “socket_ssh”.
• sN.escape_char: valid only for port N; this parameter will be used to present the menus below to the user.
Only characters from ‘^a’ to ‘^z’ (i.e. CTRL-A to CTRL-Z) will be accepted. If it is not defined, it will assume
the value of all.escape_char.
When no multiple sessions are allowed for one port, the behavior of the Cyclades-TS when someone connects
to it will be as described for version 1.3.2 and earlier. Otherwise, it will be as follows:
a. The first user to connect to the port will open a common session.
b. From the second connection on, only admin users will be allowed to connect to that port. The Cyclades-TS
will send the following menu to these administrators (defined by the parameter all.admin_users or
sN.admin_users in the file pslave.conf):
