Advanced Console Server & RIM Gateway User Manual
55
This syntax enables Users to set up SSH tunnels to all serial ports with only a single IP port 22 having to be
opened in their firewall/gateway
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 if you're connected over SSH, you'll need to type the character sequence "~~b"
TCP RAW TCP allows connections directly to a TCP socket. However while communications programs like PuTTY
also supports RAW TCP, this protocol would usually be used by a custom application
For RAW TCP, the default port address is IP Address _ Port (4000 + serial port #) i.e. 4001
– 4048
RAW TCP also enables the serial port to be tunneled to a remote console server , so two serial port devices
can be transparently interconnect over a network (see Chapter 4.1.6
– Serial Bridging
)
RFC2217 Selecting RFC2217 enables serial port redirection on that port. For RFC2217, the default port address is IP
Address _ Port (5000 + serial port #) i.e. 5001
– 5048
Special client software is available for Windows UNIX and Linux that supports RFC2217 virtual com ports, so a
remote host can monitor and manage remote serially attached devices, as though they were connected to the
local serial port (see
Chapter 4.6
– Serial Port Redirection
for details)
RFC2217 also enables the serial port to be tunneled to a remote console server , so two serial port devices can
be transparently interconnect over a network (see Chapter 4.1.6
– Serial Bridging
)
Unauthenticated Telnet Selecting Unauthenticated Telnet enables telnet access to the serial port without requiring the
user to provide credentials. When a user accesses the console server to telnet to a serial port they normally
are given a login prompt. However with unauthenticated telnet they connect directly through to port with any
console server login at all. This mode is mainly used when you have an external system (such as conserver )
managing user authentication and access privileges at the serial device level.
For Unauthenticated Telnet the default port address is IP Address _ Port (6000 + serial port #) i.e. 6001
–
6048
Web Terminal Selecting Web Terminal enables web browser access to the serial port via Manage: Devices: Serial
using the Management Console's built in AJAX terminal. Web Terminal connects as the currently
authenticated Management Console user and does not re-authenticate. See section 13.3 for more details.
Authenticate Enable for secure serial communications using Portshare and add password
Accumulation Period By default once a connection has been established for a particular serial port (such as a
RFC2217 redirection or Telnet connection to a remote computer) then any incoming characters on that port
are forwarded over the network on a character by character basis. The accumulation period changes this by
specifying a period of time that incoming characters will be collected before then being sent as a packet over
the network
Escape Character This enables you to change the character used for sending escape characters. The default is ~.
Power Menu This setting enables the shell power command so a user can control the power connection to a Managed
Device from command line when they are telnet or ssh connected to the device. To operate the Managed
