Thanks for Reply, in advance..

cheers

thanks for your reply...

i have heard that network programmers work on different layers. is that true... if yes pls tell me on which layer should i program.also tell me how much time is required to become an efficient network programmer.

cheers

thanks for your reply!!!!!

I agree with what has been said so far.

Though I use to work with programmers of all sorts.

To be a good programmer it's a way of life not a 9-5 job. Don't do it just for a job, do it because you want to do it.

I've seen to many people working with UNIX because they think the money is good, yeah it is. You'll only get out what you put in.

Write or study a small program that mimics the most common login procedures in UNIX.
You have two options here. Either, you write it yourself according to the specification
below, or you copy the file
/cab/cestud/work/edu/course/EDA263_Computer_Security/
lib/login_linux/login_linux.c into your home directory. If you choose to write
it yourself the following should be implemented.
- The program begins with displaying ”login:” and takes the username as input.
7
- Then the program writes ”Password:” and waits for the password to be entered,
which should not be visible on the terminal (use the function getpass(3) that
among other things will see to that the text is not ”echoed” on the terminal).
- The program queries the system’s user database to see if the username exists. If
this is the case it encrypts the entered password (with a known algorithm) and
ensures it corresponds to the stored encrypted password belonging to the actual
user. Suitable library routines are getpwnam(3), crypt(3) and strncmp(3).
- If the username does not exist, or if the password is wrong, the program displays
”Login incorrect” and restarts from the beginning, otherwise it writes something
like ”Welcome to this System!” and terminates.
Test that your program works by compiling and running it.

That's a 4 year old posting
