Web: Serial Forwarding Timer Mode
UCI: tservd.@port[0]. sfwd_timer_mode
Opt: sfwd_timer_mode
Forwarding timer mode (network to serial).
Idle
Timer is re-started on each received data
Aging
Timer started on the first Rx.
Web: Proxy Mode
UCI: tservd.@port[0]. proxy_mode
Opt: proxy_mode
Defines if special proxy mode is configured to allow ‘hijacking’ of
the terminal server. It allows a connection to be made from a
remote location and redirect terminal server data temporariy for
troubleshooting.
When enabled a TCP proxy server is started which listens for an
incoming TCP connection from a remote peer. Once an incoming
new TCP connection on the proxy server TCP port is accepted:
The existing terminal server TCP client connection is
disconnected.
The terminal server automatically reconnects the TCP client side
but this time to the local loopback address 127.0.0.1 and to the
local proxies TCP port number.
Once the proxy server has both local and remote TCP sessions
connected it simply forwards the data between the two
connections, taking into account the flow control.
When either side TCP socket closes, the main terminal server
client re-connects to the normal IP destination and the server
proxy returns to listening for another connection from the far
end.
