traceroute have error bind: Cannot assign requested address

Question

I have the below error:

[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**

But when i did not enter source, it works fine:

[root@pf-apispens ~]# traceroute 8.8.8.8

Please advice me on resolution. Do let me know if you need more information. Thanks in advance :)

You need to type traceroute -s with addresses which directly assign to any interfaces on your server.

You can type any of this addresses from your output of ip a:

192.168.111.xyz
192.168.111.xyzz

But not real public ip because it has assigned to your other device (e.g. router).

See man traceroute:

-s source_addr, --source=source_addr

Chooses an alternative source address. Note that you must select the address of one of the interfaces. By default, the address of the outgoing interface is used.

Thanks! let me test out and feedback :) Very interesting to know. — , Oct 03 '17 at 14:21
