Table 7-1 Ping Commands
This is numeric output only.
No attempt will be made to look up symbolic names for host addresses.
This is quiet output.
Nothing is displayed except the summary lines at startup time and when finished.
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.
This is verbose output.
Stop after sending count ECHO_REGUEST packets. With deadline option, ping waits
for cpimt ECJP_REPLY packets, until the timeout expires.
This is wait interval seconds between sending each packet.
The default is to wait for one second between each packet normally, or not to wait in
flood mode. Only super-user may set interval to values less 0.2 seconds.
This set source address to specified interface address. Argument may be numeric IP
address or name of device. When pinging IPv6 link-local address this option is
required.
If preload is specified, ping sends that many packets not waiting for reply. Only the
super-user may select preload more than 3.
You may specify up to 16 ''pad'' bytes to fill out the packet you send. This is useful for
diagnosing data-dependent problems in a network. For example, -p ff will cause the
send packet to be filled with all ones.
This specifies the number of data bytes to be sent. The default is 56, which translates
into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data.
This sets the IP Time to Live (TTL).
