Hi,

When I run below command

netstat -an | grep -i portno

I got some status which are in fin_wait state.

Now I want to kill those in fin_wait status.

When I check with below command,no ouput is displayed.

#ndd -get /dev/tcp tcp_status | grep [ip address]

I too checked with

#ndd -get /dev/tcp tcp_status | grep [port no]

ndd -get /dev/tcp tcp_status | grep -i fin_wait

ndd -get /dev/tcp tcp_status |grep -e state -e FIN_WAIT | awk '{print $1}'

I don't recieve any output to disconnect the fin_wait session.

Regards

Madhu

What do you see when run 'ndd get /dev/tcp tcp_status' by itself without any of your greps? Do you see what you're looking for?

If you are searching for IP addresses, you wi ll likely have to make sure all IP octets are 3 digits (pad with zeros if needed) like 100.005.025.200.

You might also verify FIN_WAIT states with netstat:

# netstat|grep -i fin
tcp        0      0  atl1.49152             atl2.49157              FIN_WAIT_2
tcp        0      0  atl1.49156             atl1.63505              FIN_WAIT_2

NO,, I don't get the information what i am looking for.

#ndd -get /dev/tcp tcp_status
operation failed, Invalid argument

then how can i find the hexa decimal number to disconnect the session.

# ndd -set /dev/tcp tcp_discon 0xxxxx
