hello
is it possible to identify/specify a port TCP/UDP for a file transfert
between workstations and servers

because i must give a list of ports using in my network to my provider to
organize a qos
He could only filter on udp/tpc ports

thanks,
nicolas

Hi Nicolas,

According to the research, there is a way to identify a port TCP/UDP for a
file transfer between workstations and servers. We can use network monitor
3.2 to capture the network traffic between the two computers during the
copy operation.

Download: Microsoft Network Monitor 3.2
http://www.microsoft.com/downloads/d...0af-1e08-4a21-
a26b-ec2f4dc4190d&DisplayLang=en

1. Enable the Capture Filter "IPv4.Address == <IP of the client>" and start
capture.
2. Restart one of clients to reproduce the issue.
3. Stop capture and save to *.cap file.
4. In the area of Frame Summary, you may find the SrcPort (Source port) and
DstPort (Destination port) in column of "Description" to identify the port
number that is used by copy operation.

For more detailed steps, please refer to:

How to use Network Monitor to capture network traffic
http://support.microsoft.com/kb/812953

Generally speaking, the file copy operation between Windows uses SMB
protocol. For about the ports information about SMB, please refer to the
following the KB article.

Hope it helps.

There is no logical reason that your provider should have any relevance to
file transfers between machines on your LAN.

With TCP/UDP, the only relevant port is the destination port,...the client
source port is always [or usually] random and there is no way to make any
QoS decisions based on it.

Hi,
are there any differences with usage of "direct hosting", so if NO NetBT is
involved.

Hi,

According to the research, Direct hosted "NetBIOS-less" SMB traffic also
uses port 445 (TCP and UDP).

For more information, please refer to:
