Using Ping from a character-based interface

You can use the PING command from the character-based interface to test your TCP/IP connectivity.

For example, if you want to test whether your data is traveling from your system to an interface with IP address 10.5.5.1 and host name FIRSTHOST, type PING '10.5.5.1' or PING firsthost at the command line.

You can specify either the IP address or host name of the remote node you want to reach. Ping appends the local domain to a host name if a domain name is not specified or if a period (.) does not appear at the end of the specified host name.

A successful Ping operation means your packets are reaching the 10.5.5.1 interface. An unsuccessful Ping operation indicates there is a problem with the connectivity between your system and interface 10.5.5.1.

• Pinging the loopback interface on your system
  To verify that your TCP/IP software is installed, started, and working properly, ping the loopback interface.

• Pinging your own system
  To test whether packets can reach interfaces on your local area network (LAN), ping the local interface.

• Pinging the interface on a network not directly attached to your local network
  Ping a remote interface to test whether packets can leave your network and reach a remote system. Ping a remote Domain Name System (DNS) to make sure your system can resolve domain names.
