# fping
|
|
|
|
fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up.
|
|
fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.
|
|
Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.
|
|
If a host replies, it is noted and removed from the list of hosts to check.
|
|
If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.
|
|
|
|
Unlike ping, fping is meant to be used in scripts and its output is easy to parse.
