Razor uses TCP ECHO instead of ICMP ECHO because the Net::Ping Perl module it
uses requires root privileges to do an ICMP ping.   I don't know if there's an
alternative.  You could probably hack it to not do the network check.   It calls
Net::Ping in Core.pm.   This means that port 7 TCP has to be open to allow that
traffic.
