RE: telnetd - timeout after abnormal client exit
The telnetd uses "keep_a_live" to make the decision in this case (client
gone without any FIN), so it normaly is of order of few ten minutes (a
few hours?). Can the "sysctl -w net.inet.tcp.keepidle=A_value" may
change the keep a live value? But it sounds not a good solution as even
it work, it affects the whole networking stack.
Thanks

Subject: telnetd - timeout after abnormal client exit
6.3.2 PPC
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 !
Dave

Telnetd uses the SO_KEEPALIVE option. The net.inet.tcp.keepidle
sysctl controls this but it's a global knob.
