Cyclades-TS Installation & Service Manual
APPENDIX E MULTIPLE SNIFFING
Versions 1.3.2 and earlier
Cyclades-TS allows a maximum of 2 connections to each serial port, as follows:
• 1 common session: user can execute read and write commands to the tty port. Session can be established
by a regular user or by an administrator.
• 1 sniffer session: user can execute only read commands, in order to monitor what is going on in the other
(main) session. Session can only be established by an administrator, defined by the parameter
all.admin_users or sN.admin_users in the file pslave.conf (exception: authentication none - anyone can
open a sniffer).
The first connection always opens a common session. After the second connection has been established and
the user is authenticated, the Cyclades-TS shows the following menu to the administrator user:

If the second user is not an administrator, his connection is automatically refused.
This description is valid for all of the available protocols (socket_server, socket_ssh or raw_data).
