Inspired by gavo's Linintosh server, I'm trying to build a more minimal and up-to-date one here using Debian. I have netatalk 2.2.1 up and running, but it seems that I can only connect over TCP. This is a problem for older systems (a problem I don't have with Linintosh). If I try to connect over AppleTalk I can login and see the shared folder list. But when I try to connect to a folder the chooser hangs for a few minutes and then a dialog box pops up saying "the file server's connection has unexpectedly closed down". Connecting over TCP works perfectly. I have -transall set in afpd.conf.

Any ideas?
