I’ve been bashing out my brains trying to get SMB sharing set up between my ubuntu machine in the basement and my MacBook running Leopard. It worked flawlessly in 10.4, but for whatever reason (likely a simultaneous switch from Ubuntu 7.04 to 7.10 and a mac upgrade from 10.4 to 10.5), it died.
After much digging, a rebuild of the Ubuntu machine (which lead, conveniently, to my realizing I can mount the BIG hard drive as /home/, mount the little hard drive as /, and not have to wipe and rebuild every time I want to try out a new build), and wailing and gnashing of teeth, I found fishfishfish who pointed out that it’s useful to add some Samba users to the Ubuntu system before you can log in.
Now I can quit swearing.
