Customer asks:

"
Now, when a telnet session established, if the client exit abnormally, such as plug out the network cable, the telnetd 
will wait a long time to close the session.

Can we set the telnetd’s timeout? It’s important for us.
"

Is there anything specific to telnet here, or a sysctl to the IP stack ?

Thanks !
