my.cnf errors??

[r0bit]

I keep getting "too many connections" error. I've set max connections to 1200 and I'm not positive if I've done it right. below is a copy of my.cnf. is there a way to see how many connections are in use. I'm aware of the netstat command but am unsure how to "grep" it so it will tell me how to connections are actually active. Thanks for any help
