Description
How It Can Help
hostname
The probe packet is sent to
hostname
and returned.
Verifies that a host is active on the
network.
-g
hostname
Forces the probe packet to route through a specified gateway.
By identifying different routes to the
target host, those individual routes can
be tested for quality.
-i
interface
Designates which interface to send and receive the probe packet
through.
Enables a simple check of secondary
network interfaces.
-n
Replaces host names with IP addresses.
Used when an address is more
beneficial than a host name.
-s
Pings continuously in one-second intervals. Ctrl-C aborts. Upon
abort, statistics are displayed.
Helps identify intermittent or
long-duration network events. By
piping ping output to a file, activity
overnight can later be viewed at once.
-svR
Displays the route the probe packet followed in one second
intervals.
Indicates probe packet route and
number of hops. Comparing multiple
routes can identify bottlenecks.
