SSH reachable via ipv4 but not via IPv6

  • Hi Guys,

    I just installed OMV4 and updated to the latest version. Then I setup the ipv6 network, the omv-web-gui ist reachable via ipv6 -> which means that ipv6 ist setup correctly.

    I can login via ssh ipv4, but not via ipv6. The router port is opened, and if I scan it from outside I see that the port is reachable. But If I try to connect I always get "ssh: connect to host MYIPV6 port MYPORT: Connection refused"

    lsof says:

    user@omv:~$ sudo lsof -i -n -P | grep ssh
    sshd 10958 root 3u IPv4 61885 0t0 TCP> (ESTABLISHED)
    sshd 10966 user 3u IPv4 61885 0t0 TCP> (ESTABLISHED)
    sshd 12225 root 3u IPv4 69597 0t0 TCP *:16244 (LISTEN)
    sshd 12225 root 4u IPv6 69599 0t0 TCP *:16244 (LISTEN)

    Any idea why I cannot login via ipv6?

  • Ok, obvously it is a bad idea to change network settings in omv gui. After I reverted all my settings (static ips, port) via the omv gui and set it all up again directly in the settings-files via shell everything works as I want.
