39.6.2.3

 

TCP connection re-initiation 

When a TCP session goes down in the connected state, the terminal server immediately 
restarts listening for a new TCP connection from a remote peer. 

39.6.3

 

DSR signal behaviour in UDP mode 

39.6.3.1

 

UDP session setup at startup 

If you have set option

 tcp_always_on1

, or DSR state is UP, the UDP session is setup 

immediately on startup.  
If you have set option 

tcp_always_on0

, and DSR is DOWN, the terminal server waits for 

a DSR UP signal. When DSR UP is detected, the UDP session is setup. 

39.6.3.2

 

UDP session clearing 

A UDP session is normally never cleared, but if it is closed by the network sub-system, it 
gets re-setup after a hand off timeout. 
A DSR signal DOWN event does not clear UDP session in the connected state. 

39.6.3.3

 

UDP session reset 

After UDP session clearing the terminal server takes action to resetup a UDP session 
after a hand off timeout. 
If you have set option

 tcp_always_on1

, or DSR state is UP, the UDP session is setup.  

If you have set option 

tcp_always_on0

, and DSR is DOWN, the terminal server waits for 

a DSR UP signal and then it resets up the UDP session. 

39.7

 

Terminal Server diagnostics  

The tservd process has to be running otherwise diagnostics options for terminal server 
will not be available. 

39.7.1

 

Checking Terminal Server process 

To check if Terminal Server is running, enter: 

root@VA_router:~# ps | grep tservd 

 1264 root 

1032 S  tservd 

 1769 root 

1496 S  grep tservd   

If Terminal Server is running it will be shown with its process ID. 

39.7.2

 

Terminal Server statistics 

To see Terminal Server statistics, enter: 

root@VA_router:~# tserv show stats
