Scanning and accessing windows shares

[Chad]

How would you access windows shares through java. I'm trying to set up a
java application that would scan all available windows shares on a certain
range of IPs or a certain subnet.
I have a couple of ideas of how I'd like to implement it, but if anyone
had any suggestions otherwise that'd be great.
My purpose is that my school has taken down a couple of local services
created by students that allow scanning of the network shares due to contact
by the RIAA. But then again, those services were hosted by a central server
containing a database of shared files (much like napster), but there are
programs such as ShareScan where it is not centralized and you can just
search (like any other P2P program). But ShareScan is only available to
Windows users. Also, this sounds like a fun project for someone who is
bored and doesn't feel like passing his classes.
The only program/source I could find that even attempted a similar
purpose was jFTP and it didn't work well at all, it was just ghetto
something fierce. I was going to try to modify the code, but it is a lost
cause. If anyone knows of any other source that attempt the same cause,
that'd help as well.


Thanks
Chad

I guess that you could try to use http://jcifs.samba.org/ , as it is a java
implementation of the smb/cifs protocol that is used for windows
filesharing.

Your "ghetto" problem probably doesn't have anything to do with jFTP. I
doubt you really looked at the code enough to critisize it either. If you
did, you would have noticed it uses jCIFS for SMB access. JCIFS won't
help you either. In fact I think you're going to have a hard time doing
this with Java at all. If you try to open a socket to an IP that is
routable but nobody is listening you will get no response to the initial
SYN packet and your read() will simply hang for about 1 min 15 sec. There
is *nothing* that you can do about this. Your only recourse is to create
1000s of threads and sockets which will quicky exhaust all of the
resources on your machine.

I suggest you do some homework instead.

Dang dude, chill. By asking this group I was doing my homework. But that's
irrelevant. No reason to flame for an honest question. If Java isn't
efficient for such a use, that's all you have to say. That really sucks
though, I was looking forward to this project.

Doing homework includes using your brain. You faild on this part.
