Hi
I have tried to apply both a IPv4 and IPv6 address in the server.conf file.
http_bind_address = IPv4
http_bind_address = IPv6
With sudo lsof -i -P -n | grep LISTEN I can see that only IPv6 ( the last line is used)

How can I config so both addresses are used?
Regards

Can you share the 2 line from your server.conf where you are configuring http_bind_address?

I just did some quick testing and here is what i found:

  • Graylog, by default, will listen/accept connections over IPv6
    • For example, i had http_bind_address = 0.0.0.0:9000 but was still able to reach graylog via the server’s IPv6 address
  • The IPv6 equivalent of 0.0.0.0 is [::]
    • Example: http_bind_address = [::]:9000
  • In a web browser (i tested with Google Chrome) the IPv6 address must be enclosed in square brackets [ ].
  • When BOTH IPv4 and IPv6 addresses are configured via http_bind_address, i do only see the IPv6 port via lsof
    • Example: IPv6 45735 0t0 TCP *:9000 (LISTEN)

Hi Drew

Thanks for replying.

I just tried it and when I added both IPv4 and IPv6 only IPv6 worked from the browser.

My two lines looks like this. I have masked the two IP number.

http_bind_address = ##.##.##.11:9000 (No response in web browser)

http_bind_address = [fc00:18f:11ab:####:##:##:##:11]:9000 (Works)

If I remove the IPv6 line the IPv4 line starts to work.

I have the following versions installed

Just to confirm, you are using Ubuntu Server 22?

Are you able to reach graylog locally on the server via ipv4 when ipv6 is enabled.? e.g.

curl localhost:9000
