Hey guys I am new at this and trying to gain some understanding here. I have a SFTP server that is on the internet. Its purpose is to allow people to upload and download documents. It is working fine but I would like to get some statistical information. Is there any tool in linux thats native or a 3rd party tool, web language that would give me the following statistical infromation.
1) What ip address is accessing my server
2) How much data is being downloaded and how long the session is opened
3) How much time they spent on my server
I would like to be able to get this information.
