[jcifs] Exception when trying to connect

Fri Apr 21 12:09:31 GMT 2006

Hello,

Sorry if this is a repost, but I didn't seem to recieve it from the list the
first time I tried to send... also it does not appear in the mailing list
history.

I am trying to use jcifs for copying files to a smb share and I am running
into timeout exceptions.  In order to resolve them, I wrote the following
simple application to just test for available shares.

<start code>
package smbsharetest;
import jcifs.smb.SmbFile;

public class Main {
    public Main() {
    }
    public static void main(String[] args) {
        try {
            SmbFile file = new SmbFile(args[0]);
            String[] fileList = file.list();
            for (int i = 0; i < fileList.length; i++) {
                System.out.println(fileList[i]);
            }
        } catch (Exception e) {
            System.out.println("Got an exception trying to list " + args[0]
+ ":\n" + e);
        }
    }
}
</end code>

The client is running windows xp SP2

The server is running samba v 2.2.12 (RedHat 2.1 ES)
The server is configured with security = share
I have one share available with the following configuration in smb.conf
[TESTSHARE]
   comment = SDP Share
   guest ok = yes
   path = /home/testshare
   writeable = yes

>From the client I can run the following command succesfully (with immediate
responce)
net view \\192.168.1.10
I get the results expected
Share name   Type         Used as  Comment

-------------------------------------------------------------------------------
TESTSHARE     Disk                  All groups

When running the java application:
java -jar SmbShareTest.jar smb://192.168.1.10/

I get the following Exception thrown:
Got an exception trying to list smb://192.168.1.10/

If I set the samba with a debuglevel = 5 (it may have been 10?) and check
the log for the jcifs connection, I see the following:

When doing the net view command, the Domain= line is filled in with values:
Domain=[?] NativeOS=[Windows 2002 2600 Service Pack 1] NativeLanMan=[Windows
2002 5.1]
sesssetupX:name=[<username I am logged into workstation with>]

I was wondering if anyone can give me some insight into why this error
occurs?

Thanks,
Mike
