xinetd is apparently executing with the privs of the root user, but if I
do a strings on in.tftpd there is a string in there

cannot drop privileges: %m

suggesting that tftpd doesn't run as root.  In fact the man page says it
runs as nobody by default I see now.

Anyway it's moot because you show tftpboot wide open for anyone to write
into.

Nothing in /var/log/messages about the failed write?  Add -v -v -v to
the options in /etc/xinetd.d/tftp and restart xinetd, then try again...
it should be chattier in the log and maybe you get a clue.

Hi All,

guys, what is this..?

Apr 8 04:24:53 localhost in.tftpd[6352]: WRQ from 192.168.168.12 filename /tftp boot

Found in /var/log/messages today after I added -v -v -v to /etc/xinetd.d/tftp as suggested by Andy Green. What I don't un, is, why does it show the time as 04:24:53 when others are per the pc clock time..? Cheers.

Mark Sargent.

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.
