Hi Azarudeen,

Processes running will be telned if u logged with telned and sshd if with ssh. Along with this shell specified in /etc/passwd for the respective user will be running.
I hope this cleas your doubt.

For example
PID TTY TIME COMMAND
8335 pts/ta 0:00 telnetd
8336 pts/ta 0:00 ksh

When you first connect to a UNIX system, You will get login prompt

You need to enter your password at this prompt.


These two prompts are presented by a program called getty.

These are its tasks:
1. Display the prompt login.
2. Wait for a user to type a username.
3. After a username has been entered, display the password prompt.
4. Wait for a user to enter a password.
5. Give the username and password entered by the user to the login command and
exit.

After login receives your username and password, it looks through the file /etc/passwd
for an entry matching the information you provided. If it finds a match, login executes a
shell and exits.

I hope I made it clear.

One more thing.

If no match is found in password fille , the login program issues an error message and exits. At this point
the getty program takes over and displays a new login prompt.
