Ping and traceroute usage

Objective: To learn the usage of Linux command Ping,traceroute

Usage of 1:ping:

Mans Ping

Ping: Determine if a host is responding

linux-8o9i:~ #Ping-C4 119.29.29.29PING119.29.29.29(119.29.29.29) About( -) bytes of data. -Bytes from119.29.29.29: icmp_seq=1Ttl=Wuyi  Time=101Ms -Bytes from119.29.29.29: icmp_seq=2Ttl=Wuyi  Time=75.0Ms -Bytes from119.29.29.29: icmp_seq=3Ttl=Wuyi  Time=74.4Ms -Bytes from119.29.29.29: icmp_seq=4Ttl=Wuyi  Time=74.2Ms---119.29.29.29 PingStatistics---4Packets Transmitted,4Received0% packet loss, Time3004msrtt min/avg/max/mdev =74.249/81.303/101.454/11.638Ms

64bytes: Number of ICMP packet sizes transmitted

Icmp_seq=1: Number of detections

TTL: Time to live, each route passed, the value minus 1, the initial value is: 64

Time: response times, the smaller the number, the better the network online condition

ping-sending an ICMP echo request to a network host

-C: Counter

-B (next to broadcast IP, query which active hosts are in a domain)

Usage of 2:traceroute:

Mans Traceroute

Traceroute: Tracing routes (nodes)

-N: Not resolved, only IP is displayed

119.29. 29.29

Often, many firewalls and hosts on the network will tracetoute the right to pass, so it will show *
