There were 3 attempts to fetch the volume list from the netatalk server
(PIDs 15109, 15110 and 15111) that used the login name "curlywurly$" but
didn't supplied a correct password.
The connection attempts has been established over AppleTalk (do you allow
AFP over TCP connections, too? -- compare with your afpd.conf settings) and
the AFP client was capable of the newest User Authentication Method DHX.

I believe, you mean afp connection? AppleTalk itself isn't that easy to

I don't think so. Maybe on one of the PCs one of the students installed
PCMacLAN (an AppleTalk-capable AFP-client and -server) and played a bit
around in your LAN, trying to connect to different AFP servers)

Run a 'nbplkup' on your linux box and search for occurences of the given
net.node combination (2000.x in your examples). The net range of the client
let me believe, that you have AppleTalk routing activated. In this case, you
must first find out, in which zone you should search for, or you just walk
thru all the zones available ;-)
for zone in `getzones`
echo "Search for devices in zone \"$zone\":"
If you find the machine, then run either 'ServerInfo' on a Macintosh or
asip-status.pl to examine whether it is also an AFP server and will give you
it's TCP/IP address as an answer to your FPGetSrvrInfo request:
