我下的是http://fping.org/dist/fping-3.5.tar.gz
在linux上安装后，用法如下：
[root@localhost fping-3.5]# fping -hUsage: 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 56)-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-D print timestamp before each output line-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)-H n Set the IP TTL value Time To Live hops)-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-I if bind to a particular interface-S addr set source address-t n individual target initial timeout in millisec) default 500)-T n ignored for compatibility with fping 2.4)-u show targets that are unreachable-O n set the type of service tos) flag on the ICMP packets-v show versiontargets list of targets to check if no -f specified)扫描我所在的网段：
