Testing Connectivity

The ping command is used to test connectivity with a remote computer. By using a host
name instead of an IP address, ping also verifies that your DNS server is working and
properly configured by doing a DNS lookup on the specified host name. The ping can be
interrupted by pressing CTRL+C.

To test connectivity with a remote computer, use this command:

ping {ip_address | hostname}


For example, to test connectivity with a computer with an IP address of 123.2.2.2, type:

ping 123.2.2.2

Note:

Some major Web sites do not allow pings for security reasons. However,

rtfm.mit.edu is a consistently stable site that allows remote pings.
