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.
