Except your snippet will say the $host is alive regardless of whether it's running a server on port 80 or not, which is what the poster wanted to know.

See my post below for the solution.

btw, syn isn't a protocol by itself but rather the first phase of the tcp-protocol. Net::Ping allows you to use it to be able to tcp-ping multiple hosts simultaneously. The docs of the latest version of Net::Ping describe it pretty well.
