Subject: Can I limit the number of tcp connections ?

Is there any way to limit the # tcp connections under Linux ?

I've tried ...

echo 8 > /proc/sys/net/core/somaxconn

... but I can still open 10 ssh sessions, as well as a web server.

I know I could run iptables, but I was looking for a much lower level
solution (with a smaller resource footprint).

Any clues ?

Thanks
Mark
