[Samba] strange 'notnobody' auth attempt

[David Bear]

I'm running a samba 2.x server on a freebsd box. I looked in the samba
logs today and noticed that there are a lot of logon failures. The
identity that attempts is called 'notnobody'.

I check and this identity does not exist on any of the machines
attempting to log onto the server.  Now I'm confused. I no about the
nobody account... but 'notnobody'.  Below are some snippets.

[2004/07/15 11:08:57, 1] smbd/reply.c:reply_sesssetup_and_X(1104)
  Username notnobody is invalid on this system
[2004/07/15 11:08:59, 1] smbd/reply.c:reply_sesssetup_and_X(1104)
  Username notnobody is invalid on this system
[2004/07/15 11:08:59, 1] smbd/reply.c:reply_sesssetup_and_X(1104)
  Username notnobody is invalid on this system

This kind of activity occurs for lots of different machines, not just
one machine. I'm begining to wonder if there is some trojan horse on
these clients...
