Hi All,
ok, this is working now. Both from a switch and from the pc itself via
tftp client. I wanna thank everybody for their help/patience..most of
all their patience with me. As Andy pointed out, the server changes from
root to user id, so, to get the tftp client to put a file I had to make
that file the ownership of the user running tftp-server. Oh well, it's
all a learning experience, and heck, I've learnt a lot. Cheers.
Mark Sargent.
