Thanks for your reply!
For question 1: I want the server side to be able to adapt to any
configuration of the client but I can't control that configuration in
sshd, do I need to modify the code?
For question 2:If I want to control the total number of active
sessions, I need to modify the system login module, which is not
directly determined by sshd?
