operation failed, Invalid argument on ndd -set /dev/tcp tcp_discon_by_addr

[Frank de Vries]

Hallo

I am trying to eliminate a connection of a dead process showing up under netstat -a
and netstat -an | grep ip@
(however under netstat -a it is always hanging for a minute, the more reason I want to eliminate it)

I have convertrf the ip@ to Hexa likr this:
HEX=$(print 10.214.16.153.1519.10.214.9.195.1181 | awk -F "." '{printf "%02x%02x%02x%02x%04x%02x%02x%02x%02x%04x\n",$1,$2,$3,$
4,$5,$6,$7,$8,$9,$10}')


print $HEX=0ad6109905ef0ad609c3049d
right ?

However when I use ndd command
ndd -set /dev/tcp tcp_discon_by_addr 0ad6109905ef0ad609c3049d

it gives operation failed, Invalid argument:
What am I doing wrong with my argument
(assuming that is the hexa address)

Thanks

It helps to have more info and stuff,
but I am stil back to square one.

I have legitimate reasons to use
the ndd -set /dev/tcp tcp_discon_by_addr value

However I fail to see how to exactly
interprete the value part of the command.

I use
ndd -set /dev/tcp tcp_discon_by_addr 0ad6109905ef0ad609c3049d
and the response I get is:
operation failed, Invalid argument

The 2 tcp-endpoint that I need to terminate
are:
tcp 0 0 10.214.16.153.1529 10.214.9.195.1181 ESTABLISHED

Anyone see the idiosyncrosie in my
finishing of the ndd command above ?

Hi,

You can try this to disconnect all the sessions from 10.214.9.195

To list all connections,

netstat -an |grep 10.214.9.195

ndd -get /dev/tcp tcp_status |grep 010.214.009.195

Now to kill all the connections from the command line, try this.

ndd -get /dev/tcp tcp_statis |grep 010.214.009.195 |awk '{print $1}` |while read ADD
>do
>ndd -set /dev/tcp tcp_discon 0x0$ADD
>done

Hope this helps.
