tcpip script

[Shivkumar]

Dear Sirs,

I want know a script so that the output of the below mentioned commands gets recorded in a file:

egrep 'maxfiles|maxfiles_lim' /stand/system

ndd -get /dev/tcp tcp_conn_request_max

ndd -get /dev/tcp tcp_ip_abort_interval

Appreciate if anyone can suggest the script ?

Thanks,
Shiv

Hi Shiv,


Do the following..

#script /tmp/info.txt
Script started, file is /tmp/info.txt

#egrep 'maxfiles|maxfiles_lim' /stand/system

#ndd -get /dev/tcp tcp_conn_request_max

#ndd -get /dev/tcp tcp_ip_abort_interval
#exit
Script done, file is /tmp/info.txt


Hope this helps.

Regards,
Syam

Put the stuff between the rows of *'s in a file:

*********
#!/usr/bin/sh
grep maxfiles /stand/system >> /var/tmp/yourfile
echo "" >> /var/tmp/yourfile
ndd -get /dev/tcp tcp_conn_request_max >> /var/tmp/yourfile
echo "" >> /var/tmp/yourfile
ndd -get /dev/tcp tcp_ip_abort_interval >> /var/tmp/yourfile

**********

Save the file as something like myscript.sh and make it executable (chmod 700 myscript.sh).

Now run it:

# ./myscript.sh

When it finishes look at the file /var/tmp/yourfile

actually what you are asking is pretty simple.

MYLOGFILE=somefilename
date >> $MYLOGFILE
egrep 'maxfiles|maxfiles_lim' /stand/system >> $MYLOGFILE
ndd -get /dev/tcp tcp_conn_request_max >> $MYLOGFILE
ndd -get /dev/tcp tcp_ip_abort_interval >> $MYLOGFILE
echo "--------------------------------------" >> $MYLOGFILE #separator line

just put all of the above into a file called mytcpipscript,

chmod 755 mytcpipscript

and if you want to run it lets say every hour, add the following into your crontab:

00 * * * * * /path/to/mytcpipscript

hope this helps

You could also use command grouping and direct stdout to a file i.e.

# (
> egrep 'maxfiles|maxfiles_lim' /stand/system;
> ndd -get /dev/tcp tcp_conn_request_max;
> ndd -get /dev/tcp tcp_ip_abort_interval
) > outfile

Hi Shiv,

#!/usr/bin/sh
echo "Max_Files">>/tmp/info.txt
echo "*************">>/tmp/info.txt
egrep 'maxfiles|maxfiles_lim' /stand/system>>/tmp/info.txt
echo "\n\n">>/tmp/info.txt
echo "tcp_conn_request_max">>/tmp/info.txt
echo "*************************">>/tmp/info.txt
ndd -get /dev/tcp tcp_conn_request_max>>/tmp/info.txt
echo Abort_Interval">>/tmp/info.txt
echo ""************************">>/tmp/info.txt
ndd -get /dev/tcp tcp_ip_abort_interval>>/tmp/info.txt
echo "******************* NEXT *********************\n">>/tmp/info.txt


The above is tested and OK. You may put this in cron and use it.

Matter of fact use the one below as it reports on the parameters and their values:

# (
> egrep 'maxfiles|maxfiles_lim' /stand/system;
> echo "tcp_conn_request_max: \c";
> ndd -get /dev/tcp tcp_conn_request_max;
> echo "tcp_ip_abort_interval: \c";
> ndd -get /dev/tcp tcp_ip_abort_interval;
> ) > outfile

Hi Shiva,

Sorry No pts for my last post...There was some typing mistake.

the following will work for you with the time stamp.

#!/usr/bin/sh
date>>/tmp/info.txt
echo "">>/tmp/info.txt
echo "Max_Files">>/tmp/info.txt
echo "*************">>/tmp/info.txt
egrep 'maxfiles|maxfiles_lim' /stand/system>>/tmp/info.txt
echo "">>/tmp/info.txt
echo "tcp_conn_request_max">>/tmp/info.txt
echo "*************************">>/tmp/info.txt
ndd -get /dev/tcp tcp_conn_request_max>>/tmp/info.txt
echo "">>/tmp/info.txt
echo "Abort_Interval">>/tmp/info.txt
echo "************************">>/tmp/info.txt
ndd -get /dev/tcp tcp_ip_abort_interval>>/tmp/info.txt
echo "">>/tmp/info.txt
echo "******************* NEXT *********************\n">>/tmp/info.txt
