Note In Console Server mode, when you connect through to a serial port you connect via pmshell . To will generate a
BREAK on the serial port you need to type the character sequence '~b' (and if you're doing this over SSH you'll
need to type "~~b")
SSH
It is recommended that you use SSH as the protocol where the User or Administrator connects to the console
server (or connects through the console server to the attached serial consoles) over the Internet or any other
public network. This will provide authenticated SSH communications between the SSH client program on the
remote
user’s computer and the
console server
, so the user’s communication with the serial device attached to
the console server is secure
For SSH access to the consoles on devices attached to the console server serial ports, you can use SDT
Connector . You configure SDT Connector with the console server as a gateway , then as a host , and you
enable SSH service on Port (3000 + serial port #) i.e. 3001-3048. Chapter 6 - Secure Tunneling has more
information on using SDT Connector for SSH access to devices that are attached to the console server serial
ports.
Also you can use common communications packages, like PuTTY or SSHTerm to SSH connect directly to port
address IP Address _ Port (3000 + serial port #) i.e. 3001
–3048
Alternately SSH connections can be configured using the standard SSH port 22. The serial port being
accessed is then identified by appending a descriptor to the username. This syntax supports any of:
<username>:<portXX>
<username>:<port label>
<username>:<ttySX>
<username>:<serial>
So for a User named 'fred' to access serial port 2, when setting up the SSHTerm or the PuTTY SSH client,
instead of typing username = fred and ssh port = 3002 , the alternate is to type username = fred:port02 ( or
username = fred:ttyS1) and ssh port = 22.
Or, by typing username=fred:serial and ssh port = 22, the User is presented with a port selection option:
