Hi Guys, not sure if this is the correct place to paste this question. But what I need is to know how many people logged in with the same linux user account ?
I am delivering a simple python TUI (text base UI) application to ~1k of users. The application will have its own authentication process. Users will run it via ssh. So, I need only one ssh user with basic permissions to make the ssh to the server and automatically run this python TUI application.

How many users can login with the same ssh account ? Thanks

Take a look at these options in /etc/sshd_config

MaxStartups may the the one to adjust, I cannot exactly say the max connections as I never experimented with these options.

There's not really a setting for that in sshd_config, as far as I know, in regards to general connections. It depends on the RAM on the target machine and you can probably run up hundreds if not thousands of SSH connections before you have networking or RAM troubles.

If these connection are all going to come from the same account on a single machine then you might look at SSH multiplexing. For that you would have a default limit of 10 conncurrently multiplexed sessions unless you can the MaxSessions setting.

However, there is probably a much better way to solve the task at hand than to give out shell access to thousands of people and their machines. Please describe what you are trying to do in a little more detail.
