Re: ports in samba
Port 445 is Microsoft's direct SMB over TCP (no NetBIOS in the middle) the preferred method for Windows 2000 and XP - should be a cleaner way to work with, but I do not know it well yet... According to http://support.microsoft.com/?kbid=204279 if I disable NetBios over TCP/IP on windows2000, ideally it whould use port 445 and all SMBs should come directly over TCP. But in traces I can see TCP, NBT and then SMB, for all the SMBs ???What is wrong here ? can it be possible to see TCP,SMB in traces without NBT in between ? If yes,What is the procedure? Help on this will be highly appreciated. Correct me if I had any mistake here. -- Tom -- Tom Alsberg - hacker (being the best description fitting this space) Web page: http://www.cs.huji.ac.il/~alsbergt/ DISCLAIMER: The above message does not even necessarily represent what my fingers have typed on the keyboard, save anything further. __ Do you Yahoo!?

Help on this will be highly appreciated. You need to read http://ubiqx.org/cifs/ There is a four byte header between the TCP header and the SMB message. The four byte header is used with both SMB over NBT and SMB over naked TCP. It is needed so that the length of the SMB message can be discovered. Ethereal will call this the NBT header even if you are capturing port 445 (naked TCP transport). Chris -)- -- Samba Team -- http://www.samba.org/ -)- Christopher R.
