Connectivity and Testing
Traceroute
To use a standard network application that tracks the path a packet follows to arrive at a
specified network destination, use this command:
traceroute
{
ip_address
|
hostname
}
This example shows how
traceroute
is used for internal network verification.

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:
sms2000%
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.
