How to get IP of the client in the upload/download event?

Question

Hi all,

We are planning to set up a SCP server and needs to get the client IP when it uploads/downloads files.

It seems that the upload/download evens of the FileServer do not provide the information of the client IPs. In our environment multi clients from different machines can only share the same user name / password to connect to the server (for management reason).

Any workaround to get the client IP? This is a critical requirement for our usage, any help appreciated.

Answer 1

Rebex File Server 2017 R4 adds Session property to FileUploaded and FileDownloaded event arguments and it includes the client endpoint, making it very simple to determine the client's IP address:

server.FileUploaded += (sender, e) =>
{
    // get session's IP address
    IPAddress address = ((IPEndPoint)e.Session.ClientEndPoint).Address;
    ...
};

Answer 2

Update: This approach is no longer necessary. See the new answer for a simple solution available since Rebex File Server 2017 R4.

Hi,

The solution proposed in another answer should be suitable for this scenario as well. Please give it a try and let us know if you run into any problems.

To enable SCP in addition to SFTP, you would have to add the following line as well:

server.Bind(22, FileServerProtocol.Scp);
