Seems that Avahi is used on the host for advertising SSH. Is it possible to install Avahi in a container and advertise some Samba shares as well?
Currently struggling with this setup. Seems it is blocked by dbus:
Found user 'avahi' (UID 102) and group 'avahi' (GID 106). Successfully dropped root privileges. avahi-daemon 0.6.32 starting up. dbus_bus_get_private(): Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. WARNING: Failed to contact D-Bus daemon. avahi-daemon 0.6.32 exiting.
