We have a Solaris 9 server that does not close its connections. When a
process finishes (scp in this case), netstat -a output shows that the
tranfer itself is in TIME_WAIT and sshd is ESTABLISHED. The sshd process
will remain ESTABLISHED. So this server right now has 28 logins:
(~) server % w | wc -l
28
but 72 instances of the sshd daemon running:
(~) server % ps -ef | grep sshd | wc -l
72
An example in netstat that shows what it is doing:
(~) server % scp shalmaneser.tsg.cbot.com:/etc/hosts .
(~) server % netstat -a | grep shalmaneser
server.ssh shalmaneser.tsg.cbot.com.36277 49640 47 49064 0 ESTABLISHED
server.44089 shalmaneser.tsg.cbot.com.ssh 49640 0 49112 0 TIME_WAIT
(~) server % sleep 240; netstat -a | grep shalmaneser
server.ssh shalmaneser.tsg.cbot.com.36277 49640 0 49064 0 ESTABLISHED
The Time_wait interval on this server is 60 seconds.
(~) server % ndd -get /dev/tcp tcp_time_wait_interval
60000
What am I missing? TIA, and I will summarize.
