Net::Ping, pingecho - check a host for upness
<![CDATA[
use Net::Ping;

This module contains routines to test for the reachability of remote hosts.
Currently the only routine implemented is pingecho().
pingecho() uses a TCP echo (not an ICMP one) to determine if the
remote host is reachable. This is usually adequate to tell that a remote
host is available to rsh(1), ftp(1), or telnet(1) onto.
-
hostname
-
The remote host to check, specified either as a hostname or as an IP address.
-
timeout
-
The timeout in seconds. If not specified it will default to 5 seconds.
pingecho() uses alarm to implement the timeout, so don't set another alarm
while you are using it.
