Limit number of SSH connections per user to 1

Hi, Right, all Linux distro by default enable concurrent connections. But most of these values can be modified, for example, "number of open files in a system". I believe, the method used in one linux distro might not work in another one (very rarely). I have tested a setting in ubuntu 16.04, to allow only 1 concurrent connection for a particular user, and it worked(you can specify "groups" as well, I think). I am not sure whether this setting will work for Redhat or SuSE. By the way which Platform you are running. Let me know if interested to test further. - Thank You

How many such users are there to whom you want to limit the number of connections. Do you want 1 connection\ for all added users or different numbers for different users. Both conditions are possible About myself https://www.freelancer.com/u/redssr.html

Hi, I have been a sysadmin, and had had to deal with such issues, my price might be higher than your budget, for a good reason: skills and experience cost more (for good delivery). Talk to you about this more if you agree. Regards

I can do it without limiting on port.

Hi: I have one idea. But I am bidding 30Euro for this. Lets see if that fits with you? I am working in scripting technologies for several years in several UNIX systems. Thanks!

I can apply the requested limitations within 15 minutes which will prevent non root users more than the requested multiple logins limit. Once done I can advise you on how to recreate this limitation and manage it if changes are required. Best regards Chris
