I think that this still leaves the socket open, it just denies the 
queueing of any jobs.  If security is the main concern (eg. buffer 
overflows, DoS attacks), it's probably best to just use something like 
`ipchains -A input -p tcp -s 0.0.0.0/0 -d [external ip]/32 515 -j REJECT 
-l` in combination with 'forcelocalhost@' to prevent abuse.
