User manual

P75598- Belkin OmniView Serial Console
Protocol
Select Telnet, SSH or Raw TCP as the protocol. If the users are using a Telnet client
program, select Telnet. If the users are using an SSH client program, select SSH. When
Raw TCP is selected, direct TCP socket communication is available between the Serial
Console and the remote host.
Inactivity timeout
Enable this feature to avoid a client holding on to a TCP connection while there has been
no activity on a serial port for a long period of time. If the Inactivity timeout is enabled,
and no data activity between the Serial Console and the Telnet/SSH client for the specified
inactivity timeout interval (i.e., no data activity through the serial port), the existing TCP
session will automatically be closed. If you want to maintain the connection indefinitely,
configure the inactivity timeout period to 0.
TCP Keep-alive (no configuration required)
In order to avoid TCP connection lockup
, the Serial Console will continue to check the
connection status between the Telnet/SSH client and the Serial Console by periodically
sending “keep alive” packets. If the Telnet/SSH client does not answer the packets, the
system will assume that the connection is down. The Serial Console will then close the
existing Telnet/SSH connection, regardless of the inactivity setting. This will prevent the
TCP connection from locking when an application is improperly closed or the network link
is interrupted.
4.1.4.2 Terminal Server Mode
In terminal server mode, the Serial Console’s serial port is configured to wait for data from
the device connected to the port. If data is detected, the Serial Console will initiate a TCP
session as a Telnet or SSH client to a pre-defined server. The server must be defined by
users before the port can be configured for a Telnet or SSH client. This mode can be used
to access servers on the network from a serial terminal. RawTCP is also supported with
the Terminal Server Mode.
