Hello,
Is the SSH configuration file different for each user?
I want to have two SSH users. One of them can have two sessions at the same time and one can have only one session. Is this possible?

Yes, it can be different for each user if you set that with the Match directive. When combined with the MaxSessions directive you can limit the number of concurrent remote logins. However, keep in mind that there are a great many ways to circumvent that once they are logged in. For example, with shell access they could log in and run tmux or screen and thus have multiple interactive sessions via a single SSH session.
It can be done but not via sshd configuration. man limits.conf, man pam_limits
Hello,
Thank you so much for your reply.
The syntax is:
Code:
<Username> <type> <item> <value>
I found some interesting fields for <item>:
Code:
core
limits the core file size (KB)
data
maximum data size (KB)
fsize
maximum filesize (KB)
memlock
maximum locked-in-memory address space (KB)
stack
maximum stack size (KB)
cpu
maximum CPU time (minutes)
Can I limit the amount of RAM and CPU usage for the user?
