- =head1 DESCRIPTION
-
- This module contains routines to test for the reachability of remote hosts.
- Currently the only routine implemented is pingecho().
-
- pingecho() uses a TCP echo (I<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.
-
- =head2 Parameters

- =over 5
-
- =item hostname
-
- The remote host to check, specified either as a hostname or as an IP address.
-
- =item timeout
-
- The timeout in seconds. If not specified it will default to 5 seconds.

- =head1 WARNING
-
- pingecho() uses alarm to implement the timeout, so don't set another alarm
- while you are using it.
