fping是一个类似ping的程序它使用互联网控制消息协议ICMP回显请求来确定目标主机是否正在响应。fping与ping的不同之处在于您可以在命令行上指定任意数量的目标或者指定一个包含要ping的目标列表的文件。fping将发送一个ping数据包并以循环方式移动到下一个目标而不是发送到一个目标直到它超时或回复。
安装
# 例ubuntu
sudo apt install fping# centos 7
sudo yum install fping
使用帮助
# fping -h
Usage: fping [options] [targets...]Probing options:-4, --ipv4 only ping IPv4 addresses-6, --ipv6 only ping IPv6 addresses-b, --sizeBYTES amount of ping data to send, in bytes (default: 56)-B, --backoffN set exponential backoff factor to N (default: 1.5)-c, --countN count mode: send N pings to each target-f, --fileFILE read list of targets from a file ( - means stdin)-g, --generate generate target list (only if no -f specified)(give start and end IP in the target list, or a CIDR address)(ex. fping -g 192.168.1.0 192.168.1.255 or fping -g 192.168.1.0/24)-H, --ttlN set the IP TTL value (Time To Live hops)-I, --ifaceIFACE bind to a particular interface-l, --loop loop mode: send pings forever-m, --all use all IPs of provided hostnames (e.g. IPv4 and IPv6), use with -A-M, --dontfrag set the Dont Fragment flag-O, --tosN set the type of service (tos) flag on the ICMP packets-p, --periodMSEC interval between ping packets to one target (in ms)(in loop and count modes, default: 1000 ms)-r, --retryN number of retries (default: 3)-R, --random random packet data (to foil link data compression)-S, --srcIP set source address-t, --timeoutMSEC individual target initial timeout (default: 500 ms,except with -l/-c/-C, where its the -p period up to 2000 ms)Output options:-a, --alive show targets that are alive-A, --addr show targets by address-C, --vcountN same as -c, report results in verbose format-d, --rdns show targets by name (force reverse-DNS lookup)-D, --timestamp print timestamp before each output line-e, --elapsed show elapsed time on return packets-i, --intervalMSEC interval between sending ping packets (default: 10 ms)-n, --name show targets by name (reverse-DNS lookup for target IPs)-N, --netdata output compatible for netdata (-l -Q are required)-o, --outage show the accumulated outage time (lost packets * packet interval)-q, --quiet quiet (dont show per-target/per-ping results)-Q, --squietSECS same as -q, but add interval summary every SECS seconds-s, --stats print final stats-u, --unreach show targets that are unreachable-v, --version show version-x, --reachableN shows if N hosts are reachable or not

# 测试多个主机是否可达
