Thanks for the input tybalt89! I tested the version I had against the version you wrote on 7052 servers using time. The version I had performed better even after I added the timeout back into your version.

My Version:

real    1m6.522s
user    0m59.375s
sys     1m5.178s

[download]

Your Version:

^C

real    3m10.862s
user    0m0.685s
sys     0m0.507s

I'm not familiar enough with it. And note some of the servers in my list may no longer exist so it may have been hung up on some?
