Selam Emre,

LOGIN PROCESS
When a user successfully logs in, sshd does the following:
1. If the login is on a tty, and no command has been specified,
prints last login time and /etc/motd (unless prevented in the configuration file or by $HOME/.hushlogin; see the FILES section).
2. If the login is on a tty, records login time.
3. Checks /etc/nologin; if it exists, prints contents and quits (unless root).
4. Changes to run with normal user privileges.
5. Sets up basic environment.
6. Reads the file $HOME/.ssh/environment, if it exists, and users
are allowed to change their environment. See the
PermitUserEnvironment option in sshd_config(5).
7. Changes to user's home directory.
8. If $HOME/.ssh/rc exists, runs it; else if /etc/ssh/sshrc
exists, runs it; otherwise runs xauth. The ``rc'' files are
given the X11 authentication protocol and cookie in standard
input.
9. Runs user's shell or command.
