Hi.
This is just another one of these stupid newbie(:)) questions (sorry for that!!):
As I previously used DD-WRT I am used to be able to set up the number of maximum connections (ip_conntrack_max).
I was looking for that in openWRT and found it in /proc/sys/net/ipv4/.
In the forum I found the command "echo 4096 > /proc/sys/net/ipv4/ip_conntrack_max". Looks clear and simple: "it writes "4096" to ip_conntrack_max" was my first assumption.
But when I vi it, there is nothing written inside.
What does this "echo >"do exactly?
And what is this "ip_conntrack_max"?? Is it a file? A symlink (can't rm it)? Or anything else?
And the most important: what is the default number of max connections in open WRT?
DO I have to set this ip_conntrack_max for better performance (in DD-WRT '4096' is the best and most stable)?
