The default is 56, which translates into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data. -c 数目在发送指定数目的包后停止。 -c count Stop after sending count ECHO_REQUEST packets. With deadline option, ping waits for count ECHO_REPLY packets, until the timeout expires. -q 不显示任何传送封包的信息只显示最后的结果。 -q Quiet output. Nothing is displayed except the summary lines at startup time and when finished. 二、需要安装fping命令(apt-get -y install fping --force- yes 或yum -y install fping) fping - sends ICMP ECHO_REQUEST packets to network hosts fping -ef /root/iplist .txt > ping .log 2>&1 ==================================说明============================================ 执行结果 cat ping .log 10.1.1.101 is alive (0.66 ms) 10.1.1.102 is alive (1.22 ms) 10.1.1.104 is alive (1.28 ms) 10.1.1.105 is alive (1.26 ms) 10.1.1.103 is unreachable cat iplist.txt 10.1.1.101 10.1.1.102 10.1.1.103 10.1.1.104 10.1.1.105 -f Read list of targets from a file . -e Show elapsed (round-trip) time of packets |
