能夠一次ping一個網段,對網管人員來說,可以提供不少方便.
使用 fping 就可以達到這樣功能.

$ fping -c3 -sg 192.168.1.1 192.168.1.10
192.168.1.1  : [0], 96 bytes, 0.33 ms (0.33 avg, 0% loss)
192.168.1.10 : [0], 96 bytes, 0.06 ms (0.06 avg, 0% loss)
192.168.1.1  : [1], 96 bytes, 0.56 ms (0.44 avg, 0% loss)
192.168.1.10 : [1], 96 bytes, 0.04 ms (0.05 avg, 0% loss)
192.168.1.1  : [2], 96 bytes, 0.52 ms (0.47 avg, 0% loss)
192.168.1.10 : [2], 96 bytes, 0.04 ms (0.04 avg, 0% loss)

192.168.1.1  : xmt/rcv/%loss = 3/3/0%, min/avg/max = 0.33/0.47/0.56
192.168.1.2  : xmt/rcv/%loss = 3/0/100%
192.168.1.3  : xmt/rcv/%loss = 3/0/100%
192.168.1.4  : xmt/rcv/%loss = 3/0/100%
192.168.1.5  : xmt/rcv/%loss = 3/0/100%
192.168.1.6  : xmt/rcv/%loss = 3/0/100%
192.168.1.7  : xmt/rcv/%loss = 3/0/100%
192.168.1.8  : xmt/rcv/%loss = 3/0/100%
192.168.1.9  : xmt/rcv/%loss = 3/0/100%
192.168.1.10 : xmt/rcv/%loss = 3/3/0%, min/avg/max = 0.04/0.04/0.06

      10 targets
       2 alive
       8 unreachable
       0 unknown addresses

       0 timeouts (waiting for response)
      30 ICMP Echos sent
       6 ICMP Echo Replies received
       0 other ICMP received

 0.04 ms (min round trip time)
 0.25 ms (avg round trip time)
 0.56 ms (max round trip time)
        2.813 sec (elapsed real time)

-c num , 每一host送多少封包
-s 產生最後的總結報告
-g 產生指定網段的ip list, 除了上面的列舉式,也可以用 192.168.1.0/24 這種表達方式.
因為這樣會太長,就不列出,各位可以自行測試.
