Do you use an ftp server on the MorphOS side? If so, which one - I've never managed to get one working for me.
Currently I use the slow (but simple) kludge of Apache running on each machine and a webshare folder. Wget lends itself fairly well to MorphOS's mime actions, but I'd far rather have mounted shares.
I use rc-ftdp 2.74 (68k) from Nov 02 2002. Dunno if it is best, but at least it works here quite reliably (MorphOS 3.3).
