In the process of network troubleshooting, in addition to the common ping command, there are other useful commands that can be used for troubleshooting. Here are some troubleshooting commands that are better than the ping command:
-
traceroute：
- The traceroute command is used to trace the path of network packets from source to destination. It shows the IP address of each router the packet passes through and provides the round trip time (RTT) for each router.
- Example:
traceroute google.com
-
mtr：
- The mtr command combines the functions of ping and traceroute to display the RTT statistics of each router that network packets pass through. It provides more detailed tracking and statistics.
- Example:
mtr google.com
-
nslookup/dig：
- The nslookup and dig commands are used to query Domain Name System (DNS) records to obtain information associated with a hostname or IP address, such as IP address, domain name resolver, MX records, etc.
- Example:
nslookup google.comordig google.com
-
netstat：
- The netstat command is used to display network connections, listening ports, and network statistics. It helps you check running network services, open connections, and port usage.
- Example:
netstat -ano
-
tcpdump：
- The tcpdump command is used to capture and analyze network packets. It can display the contents of data packets during transmission in real time, helping you analyze network traffic and troubleshoot problems.
- Example:
tcpdump -i eth0
These commands can provide more detailed network troubleshooting information to help you diagnose and solve network problems. Depending on the situation, you can choose the appropriate command to troubleshoot. Note that proper permissions and network access may be required to use these commands.
