[jcifs] ServerEnum2 Problems on smb:// scan

[Matthew Tippett]

Hello,

I originally sent this email with two network traces attached.  This is 
larger than the unmoderated limit, so I am posting again sans 
attachments and will place the attachments at

Calling SmbFile("smb://").listFiles() has some funny behaviour on our 
system.  I have done some initial debugging and will report more as I 
find it.

The first scan for domains works fine, on subsequent scans the following
exception occurs..

jcifs.smb.SmbException: 
GetServerEnum2Response[command=SMB_COM_TRANSACTION,received=true,errorCo
de=0x00000000,flags=0x0098,flags2=0x0001,tid=51202,pid=64459,uid=0,mid=2

ffset=64,dataDisplacement=0,setupCount=0,pad=0,pad1=0,status=2320,conver
ter=0,entriesReturned=0,totalAvailableEntries=45]

The stack dump against 0.7.0b9 is

at jcifs.smb.SmbFile.listFiles(SmbFile.java:1267)

at com.casero.eden.service.cifs.CIFSCrawler.run(CIFSCrawler.java:67)
at java.lang.Thread.run(Thread.java:536)

So, have a look, there are a few differences,

     o The first time it does an initial connect with *SMBSERVER
     o The first time it does a Session Setup and X

The exception is thrown because the Server2Enum call has a status of 
2320 (which is unknown even to ethereal).

The client machine is Windows ME.

More details tomorrow as I hunt things down...

Regards,

Matthew
