Fping是一种将ICMP回声探测发送到网络主机的程序，与ping类似，因此它允许用户检查远程主机是否处于启动或关闭状态。使用Fping命令，我们可以一次检查多个主机。本文介绍“如何安装Fping命令以及Fping命令的用法”
要安装Fping命令，请使用以下命令-
$ sudo apt-get install fping
样本输出应如下所示–
Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: gtk2-engines-pixbuf libbs2b0 libopusfile0 libpyside1.2 libqmmp-misc libqmmpui0 libshiboken1.2 libsidplayfp libtidy-0.99-0 linux-headers-4.2.0-27 linux-headers-4.2.0-27-generic linux-image-4.2.0-27-generic linux-image-extra-4.2.0-27-generic linux-signed-image-4.2.0-27-generic php7.0-opcache python-beautifulsoup python-feedparser python-html2text python-magic python-oauth2 python-pyside.qtcore python-pyside.qtgui python-pyside.qtnetwork python-pyside.qtwebkit python-pysqlite2 python-regex python-sqlalchemy python-sqlalchemy-ext python-support python-unity-singlet python-utidylib Use 'apt-get autoremove' to remove them. The following NEW packages will be installed: fping 0 upgraded, 1 newly installed, 0 to remove and 1 not upgraded.

要运行Fping，请使用以下命令-
$ fping nhooo.com
样本输出应如下所示–
nhooo.com is alive
要测试多个站点，请使用以下命令–
$ fping www.nhooo.com www.google.com
样本输出应如下所示–
www.nhooo.com is alive www.google.com is alive
如果主机列表存储在文件中，请使用以下命令–
$ fping < hosts.txt
样本输出应如下所示–
www.nhooo.com is alive www.google.com is alive
要获取有关fping的更多信息，请使用以下命令–
$ fping -help
样本输出应如下所示–
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 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 version targets list of targets to check (if no -f specified)
