fping 은 ping에서 조금 진보된 형태로 멀티로 아이피를 받거나…대역으로… 혹은 파일로 아이피를 설정해서 icmp 패킷의 요청을 응답해주는 프로그램입니다.
관제 혹은 네트워크 작업시에 적절히 응용해서 사용하기 좋습니다.

# fping -help
Usage: fping [options] [targets…]
-a show targets that are alive
-A show targets by address
-b n amount of ping data to send, in bytes (default 68)
-B f set exponential backoff factor to f
-c n count of pings to send to each target (default 1)
-C n same as -c, report results in verbose format
-e show elapsed time on return packets
-f file read list of targets from a file ( – means stdin) (only if no -g specified)
-g generate target list (only if no -f specified)
(specify the start and end IP in the target list, or supply a IP netmask)
(ex. fping -g 192.168.1.0 192.168.1.255 or fping -g 192.168.1.0/24)
-i n interval between sending ping packets (in millisec) (default 25)
-l loop sending pings forever
-m ping multiple interfaces on target host
-n show targets by name (-d is equivalent)
-p n interval between ping packets to one target (in millisec)
(in looping and counting modes, default 1000)
-q quiet (don’t show per-target/per-ping results)
-Q n same as -q, but show summary every n seconds
-r n number of retries (default 3)
-s print final stats
-t n individual target initial timeout (in millisec) (default 500)
-u show targets that are unreachable
-v show version
targets list of targets to check (if no -f specified)
