一张图,彻底看懂网工必备Linux网络命令

一张图，彻底看懂网工必备Linux网络命令

把 Linux 常用网络命令分了 5 大类，帮你轻松搞定网络问题：

1. 连通性排查：用ping看网络通不通，traceroute找卡在哪，ifconfig/ip查 IP 和网卡状态。

2. 信息与配置：nslookup查域名解析，arp看局域网设备映射，hostname改主机名。

3. 服务与下载：wget下载文件，curl测接口 / 请求，mtr同时看延迟和丢包。

4. 传输与工具：scp/sftp传文件，rsync同步数据，iperf测带宽性能。

5. 监控与统计：iftop看谁占了带宽，tcpdump抓包分析，nmap扫端口。

这些命令覆盖了日常运维、故障排查的大部分场景，新手也能快速上手，排查网络问题效率翻倍。
