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:
