I have developed a NT_TRANSACT_NOTIFY_CHANGE that use a protocol
SmbComNtTransaction. I add a Setup Words into method :
nt writeSetupWireFormat(byte[] dst, int dstIndex)
{
int start = dstIndex;
writeInt4( FILE_NOTIFY_CHANGE_FILE_NAME, dst,
dstIndex );
dstIndex += 4;
writeInt2( fid, dst, dstIndex );
dstIndex += 2;
byte b = (byte)(watchTree?1:0);
dst[dstIndex++] = b;
dst[dstIndex++] = (byte)0x00; // Reserved return
dstIndex - start;
}
I added this code in the costructor :
NtTransactNotifyChange(int completionFilter, int fid, boolean
watchTree ) {
this.completionFilter = completionFilter;
this.fid = fid;
this.watchTree = watchTree;
command = SMB_COM_NT_TRANSACT;
timeout = 0xFFFFFFFF;
System.out.println("process to
NtTransactNotifyyyChange");
function = NT_TRANSACT_NOTIFY_CHANGE;
totalDataCount = 0;
maxParameterCount = 0;
maxDataCount = 4096;
maxSetupCount = (byte)0;
parameterCount = 0;
setupCount = 4;
}
When I call the transaction, the server response is a timeout.
I tryed to delete setupWordCount for look if the server can analyze a
massage : A server respnse is a nt_trans : parameter incorrect.
I am looking a bytes of message : a lenght of message is 81 bytes : the
first bytes is header, after the header i find a Word Count whith a value of
23 (19 byte of standard parameters - MaxSetupCount, Reserver,
TotalParameterCount, MaxParameterCount....) and 4 bytes for a setupwords[4]
My problem is that after 30 sec, the server response is timeout.
The last trace that strace in SUSE write is :
read(5,
"\xff\x53\x4d\x42\xa0\x00\x00\x00\x00\x18\x03\xd0\x00\x00\x00\x00\x00\x00\x0
0\x00\x00\x00\x00\x00\x01\x00\xa1\x84\x64\x00\x04\x00\x17\x00\x00\x00\x00\x0
0\x00\x00\x00\x00\x00\x00\x04\x00\x00\x00\x00\x10\x00\x00\x00\x00\x00\x00\x0
0\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x04\x04\x00\x08\x07\x00\x00\xa
1\x2a\x01\x00\x00\x00", 81) = 81 <0.000079>
Another people has writed NT_TRANSACT_NOTIFY_CHANGE ?
Thank's
