About ipv6 #53

How to configure IPv6 in rsyslog. conf? Can we judge the success of sending IPv6 information locally by tpdump?

rgerhards commented 5 years ago

there is no special option needed. If you have dual stack - or only ipv6 - it's active :-)

Excuse me, I have two questions to ask you.

  1. Can the ipv6 function be used normally on a 32-bit system?
  2. I don't currently have an ipv6 environment. I tried to use tcpdump to capture packets on the local device to verify the ipv6 functionality of rsyslog. I configured an ipv6 address in the rsyslog.conf that does not exist in the remote end, but I can't catch any information related to ipv6. Is this normal?

Nothing special - IPv6 is fully supported for over 10 yrs.

  • I don't currently have an ipv6 environment. I tried to use tcpdump to capture packets on the local device to verify the ipv6 functionality of rsyslog. I configured an ipv6 address in the rsyslog.conf that does not exist in the remote end, but I can't catch any information related to ipv6. Is this normal?

For a good answer, I would post this to a Linux networking forum.

what I mean is: I am not 100% sure if the IP stack sends out something if you want to connect to an non-existing IPv6 address. Probably an ARP request. Well, should send the packet if you address it to a non-local IPv6 address AND if you have configured the IPv6 gateway. You see, all networking questions.

You don't need rsyslog to check this. You can just use netcat (nc).

It's good that you move to IPv6 and I understand you have questions. But these are better targeted towards a networking forum because they are the same for all software. While I also have a network engineer education, it's long since I actively maintained networks - plus my time is limited. Again: great to see you finally move towards IPv6!
