ndd command syntax

[Shivkumar]

Hi,

What is the command to see all tuned tcp/ip parameters on the box ?

For example:-
[BigGuy:/home/sksonkar]$ ndd -get /dev/tcp tcp_conn_request_max

4096

The above command shows one value at a time.

Just wondering is there a command syntax which helps to view all the tcp/ip tuned parameters at one time.

Thanks,
Shiv

ndd -h

ndd -get /dev/ip (parameter)
ndd -set /dev/ip (parameter) value (0/1 - etc..)

Hi Shiv:

You could do something like this:

ndd -get /dev/tcp ?|grep -v "^?" > /tmp/nddargs

while read ARG NULL
do
echo "${ARG} = \c";ndd -get /dev/tcp ${ARG}
done < /tmp/nddargs | more

Regards!

Hi,

There isn't an option to show the values of all the parameters at one time, but it would be a clever little hack to script it from the output of 'ndd -h'.

James,

Do i need to put below in a shell script and execute ?

----
ndd -get /dev/tcp ?|grep -v "^?" > /tmp/nddargs

while read ARG NULL
do
echo "${ARG} = \c";ndd -get /dev/tcp ${ARG}
done < /tmp/nddargs | more

Thanks,

Hi Shiv:

Well, yes, it would be convenient to build this into a reusable script. A slightly better version is this:

# cat /tmp/ndd
#/usr/bin/sh
typeset FILE=/var/tmp/$$
ndd -get /dev/tcp ? | grep -v "^?" | cut -f1 -d"(" > ${FILE}
while read ARG NULL
do
echo "${ARG} = \c";
ndd -get /dev/tcp ${ARG}
done < ${FILE}
rm ${FILE}
exit 0

...call the script '/tmp/ndd' and do:

# /tmp/ndd | more

Regards!
