Ubuntu – How to restrict users of computers to 2 hours only

user-management

I work in a library and I want to restrict users of computers to 2 hours only. Then lock them out and allow another user to use the computer. I am using Ubuntu and would like to know if there is a free software I could use to do this.

This Bash script will lock screen after an interval you specify and require the password to reactivate it.

It gives a count down notification bubble and soft sound at 2 hours, 1 hour, 45, 30, 15, 10, 5, 3, 2 and 1 minute remaining.

As I wrote the script I'd be happy to modify it for anyone. Because it's written in Bash millions of other people with beginner scripting skills can change it as well.

Ubuntu – How to restrict a specified SSH user to connect only from one IP or hostname

See man sshd_config. There is possibility to add AllowUsers block where you can specify both user and host like this:

AllowUsers user@host # or IP

Of course you need to specify also other users you want to allow login from, if you have some.

Another solution (depends on bug fixes!)

As I think about it once more, there is possibility to modify your sshd_config like this:

Match Host !hostname
    DenyUsers user
Match Host hostname
    AllowUsers user

This would easily block all users except from user from hostname and from everywhere else it would block user.

BUT it doesn't work, because of few bugs reported upstream [1] [2]. But we got it promised it will get fixed in next release.
