[jcifs] error

[Anish Acharya]

Unfortunetly the exception is thrown within jCIFS and I have no way to
catch it 
without modifying the jCIFS source.  I will try one of the more robust
examples
and examine the behaviour.

Thanks,

Chances  are this is one particular host that is doing this. Find out
which
one  and  then  run one of the examples (like Exists) on it to see what,
if
anything,  is  successfully  getting  through  (a really persistant
crawler
might  do  this automatically). I think you'll find that jCIFS is
sending a
legitimate  request  but  the  server  is  just  closing the socket
rudely.
Probably  some  very  unsophisticated  non-windows server (like an
advanced
super-printer  that  has  a  built-in  SMB  server) without support for
RAP
functions or it's firewalled, etc.

When  scanning  large WANs you will see quite a bit of stuff like this.
You
should catch these *inside* your loop, print it or log it, and move on.
