简单情况:

• # cxxu @ cxxuAli in ~ [9:37:59] C:130
  $ hostname -I
  172.16.27.115

复杂情况(譬如虚拟机/wsl子系统)

wsl 扫描到了多块网卡(包括软件虚拟化出来的)

# cxxu @ CxxuWin11 in ~ [9:35:50]
$ hostname -I
172.29.112.1 192.168.6.1 192.168.80.1 10.61.5.232

路由跟踪(trace route)

• Tracert on Windows Returns Slower than on Linux - Stack Overflow
• How to Use TRACERT to Troubleshoot TCP/IP Problems in Windows (microsoft.com)
• How to Read a Traceroute – InMotion Hosting Support Center

How to Use the TRACERT Utility

• tracert(windows) 通过发送icmp数据包来跟踪路由
• 用RTT显示结果
• 跟据TTL来计算

• The TRACERT diagnostic utility determines the route to a destination by sending Internet Control Message Protocol (ICMP) echo packets to the destination.

  • In these packets, TRACERT uses varying IP Time-To-Live (TTL) values.
    • Because each router along the path is required to decrement the packet's TTL by at least 1 before forwarding the packet,
  • the TTL is effectively a hop counter.
  • When the TTL on a packet reaches zero (0), the router sends an ICMP "Time Exceeded" message back to the source computer.

• TRACERT sendsthe first echo packet with a TTL of 1and increments the TTL by 1 on each subsequent transmission发送, until the destination responds or until the maximum TTL is reached.

  • The ICMP “Time Exceeded” messages that intermediate routers send back show the route.
  • Note however that some routers silently drop packets that have expired TTLs, and these packets are invisible to TRACERT.

• TRACERT prints out an ordered list of the intermediate routers that return ICMP "Time Exceeded" messages.

  • Using the -d option with the tracert command instructs TRACERT not to perform a DNS lookup on each IP address, so that TRACERT reports the IP address of the near-side interface of the routers.

tracert(windows)&traceroute(unix-like)

The Windows tracert tool sends ICMP echo requests; many routers will just DROP ICMP echo requests. Thus the tool must wait for an internal timeout before declaring that route dead.

The Linux traceroute tool sends UDP connection attempts; routers have to forward these packets, so it works pretty reliably. This means the tool won’t have to wait for timeouts from most of the routers along the way.

The Windows tracert waits about 1 second between hops. The Linux traceroute does not wait between hops. There is no documented option for the Windows tracert to disable this delay.

• Traceroute sends out three packets per TTL increment.
• Each column corresponds to the time is took to get one packet back (round-trip-time).

This tries to account for situations such as:

• A traceroute packet is routed along a different link than other attempts

• A traceroute packet is dropped

• 可见,traceroute 每次发送16个信息包
• 可以指定最大跳数
  • 但是如果再最大跳数之间就路由到了终点主机,就会提前停止
