Additional Context

Connecting by SMB to IP works.

I've tried searching issues, but cannot find same error message. Sorry if this is duplicate.

This indicates that you already have Avahi/mDNS on your host. See https://github.com/mbentley/docker-timemachine#conflicts-with-samba-andor-avahi-on-the-host

Do you have Samba also running on the host?

Sorry, I indeed was running avahi-daemon on host system. Disabled systemd service avahi-daemon and removed packages avahi and nss-mdns. Also I've changed my hostname to 'infinity.local' to remove System host name is set to 'localhost'. This is not a suitable mDNS host name, looking for alternatives.

Rebooted both linux server and mac.

Now I have two entries in "Network" tab:

And both with same STR give same error:

Connecting with Go > Connect to server via IP to SMB still works:

And immense gratitude for your time in answering and supporting these images.

mbentley commented 7 months ago

OK so you can connect. I'm honestly not sure about why you would not just be able to connect through Finder directly - I am able to connect directly via Finder when I am using both macvlan and --net=host

How are you changing the hostname to infinity.local? Are you setting that for your actual host that is running Docker or is that something you're setting on the container? Is that valid in your local DNS?

So I just did a quick test and this works fine where the container ends up getting my host (in my case I have a test VM called vmlab and it shows up as vmlab and I can connect directly through finder with it using the test credentials:

docker run -d --restart=always --name timemachine --net=host -e TM_USERNAME="timemachine" -e TM_UID="1000" -e TM_GID="1000" -e PASSWORD="timemachine" -e SET_PERMISSIONS="false" -e VOLUME_SIZE_LIMIT="1 T" -v timemachine-data:/opt/timemachine -v timemachine-var-lib-samba:/var/lib/samba -v timemachine-var-cache-samba:/var/cache/samba -v timemachine-run-samba:/run/samba mbentley/timemachine:smb

mbentley commented 7 months ago

Yeah, so I can almost guarantee it's setting ADVERTISED_HOSTNAME. Same issue as https://github.com/mbentley/docker-timemachine/issues/152
