Ping Commands
Syntax:
ip ping [-LRdfnqrv] [-c count] [-i wait] [-l preload]
[-p pattern] [-s packetsize] [-t ttl]
[-I interface address] host
This command send ICMP echo request message to a remote host. The command options are case sensitive.
OPTION
-L
This suppresses loopback of multicast packets.
This option only applies if the ping destination is a multicast address.
-R
This is record route.
It includes the RECORD_ROUTE option in the ECHO_REQUEST packet and
displays the route buffer on returned packets. Note that the IP header is only large
enough for nine such routes. Many hosts ignore or discard this option.
-d
This set the SO_DEBUG option on the socket being used.
-f
This is flood ping.
For every ECHO_REQUEST sent a period ''.'' is printed, while for every
ECHO_REPLY received a backspace is printed. This provides a rapid display of how
many packets are being drooped. If interval is not given, it sets interval to zero and
outputs packets as fast as they come back or one hundred times per second,
whichever is more. Only the super-user may use his option with zero interval.
-n
This is numeric output only.
No attempt will be made to look up symbolic names for host addresses.
-g
This is quiet output.
Nothing is displayed except the summary lines at startup time and when finished.
-r
Bypass the normal routing tables and send directly to a host on an attacked interface.
If the host is not on a directly attached network, an error is returned. This option can
be used to ping a local host through an interface that has no route through it provided
the option -I is also used.
-v
This is verbose output.
-c count
Stop after sending count ECHO_REGUEST packets. With deadline option, ping waits
for cpimt ECJP_REPLY packets, until the timeout expires.
