Scripting at start up
 

hello,

I would like to have a few pointers on scripting, be it shell scripting or etc, whichever appropriate.

I would like to do the following automatically when i log on:

telnet 192.168.1.1 (my DSL router)
admin (username)
admin (password)
cd /proc/sys/net/ipv4/netfilter
echo 2048 > ip_conntrack_max
echo 50 > ip_conntrack_generic_timeout
echo 5 > ip_conntrack_tcp_timeout_close
echo 120 > ip_conntrack_tcp_timeout_close_wait
echo 1200 > ip_conntrack_tcp_timeout_established
echo 120 > ip_conntrack_tcp_timeout_fin_wait
echo 60 > ip_conntrack_tcp_timeout_time_wait
echo 10 > ip_conntrack_udp_timeout

I have tried putting these into .bash_profile, but it will only proceed up to the first line, and stops when the router asks for username/password.

Any help is appreciated, thanks.


best regards

It would be better to have the DSL box do that for you. I'm assuming that DSL supports sysctl, so you can modify /etc/sysctl.conf to do it for you:
Then just have sysctl read the new values with sysctl -p. Or, just add them to one of your startup scripts:

Nope, my DSL router (it's a D-Link) does not support sysctl.

Maybe I should rephrase my question:

how to I use scripting to automate telnet login to my router?

I see DSL here so often meaning Damn Small Linux that it never occurred to me :) Have you tried something like the following expect script from http://linuxgazette.net/issue50/tag/34.html?
You'd need to change the last line from interact to send your echo statements, but it looks like it can do what you need.
