Ping Utility

The ping utility sends ICMP packets to a host and listens for a return

packet. This ensures that you have network connectivity to the

destination server. If you do not receive a response, the destination host

may not be available or it may indicate that your 3Com Email Firewall

does not have network connectivity.

Try to ping other hosts internal and external to your network. If you

cannot ping any hosts external to your network, your Internet connection

is most likely down.

For more detailed information on routing connectivity between the two

hosts, use the traceroute utility.
