traceroute 有錯誤綁定:無法分配請求的地址

  • October 8, 2017

我有以下錯誤:

[root@~]# traceroute -s 'publicIP' 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets
**bind: Cannot assign requested address**

但是當我沒有輸入原始碼時,它工作正常:

[root@pf-apispens ~]# traceroute 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets

請就解決方案給我建議。如果您需要更多資訊,請告訴我。提前致謝 :)

您需要輸入traceroute -s直接分配給伺服器上任何介面的地址。

您可以從以下輸出中鍵入任何地址ip a

192.168.111.xyz
192.168.111.xyzz

但不是真正的公共 IP,因為它已分配給您的其他設備(例如路由器)。

man traceroute

-s source_addr, –source=source_addr

選擇備用源地址。請注意,您必須選擇其中一個介面的地址。預設情況下,使用出介面地址。
