Need SSH logging on a Linux server

Need SSH logging on a Linux server, session logging of the people on a Linux server to see who did what on a Linux server? Hope a simple BASH solution is available; if there are many other questions, please let me now or I may cancel this project and start another one. If you have a solution in a script; that is seen great if it is a bash only solution If a product is required; only interested in a quality free product that will work, Please provide all commands and or a script to do the above details and allow time for testing; for all the above items, on one or more servers Is $10 ok? (If not how much?) (Did I miss something?) We can work on Google Hangouts or any desktop sharing you may have? Please share your thoughts? If you have questions please confirm you read all of this, before reaching to me. My first question to you will be; did you read the project details? Please only BID if you know how to do this and are certain you can do this? Expecting this is something easy for about $10 or so and will be something person on this topic would know and understand. Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Please just don’t ask me to give you the root password; that will tell me you have not read even anything on these requirements.
