First and foremost,
netstat -lup | grep tftp
or (probably faster):
netstat -lnup | grep 69
This will show you the name of the process that listens on the standard
TFTP (UDP) port, if any.
Debian includes 3 (or maybe 4) tftp servers:
tftpd - Old and probably less maintained version
tftpd-hpa - A newer version. Slightly larger but this is probably the
one to use.
atftpd - Yet another tftpd. Likewise, better than tftpd .
Both atftpd and tftpd-hpa can run either as stand-alone daemons or from
inetd. Check /etc/default/<package-name> and the docs directory for the
details. IIRC the scripts of the package already run update-inetd for
you.
Another option is to use dnsmasq. If you already happen to use it as a
DNS and/or DHCP server, then you might have noticed the extra TFTP
serving it has added in its latest versions. It only supports read-only
access. But you don't really want to support that insecure tftp upload,
right?
Logs from all the above go to /var/log/daemon.log .
