Linux PAM tutorials

This repo contains the code from my old Linux PAM tutorials, which are not online anymore as I started working on a completely different topic and havent't ported them on a new hosting platform yet.

pam-application

Contains a simple C program that does authentication against a PAM configuration file.

Contents:

  • main.c is the program
  • pam_example is the PAM configuration file that must be put in /etc/pam.d/

Dependencies

Requires to have the libpam-dev package installed. Check the correct name for your distribution

Building

Run gcc -o run_pam.o main.c -lpam -lpam_misc

pam-module

Contains a simple PAM module that performs authentication, account, session and password.

Contents:

  • src/main.c is the module code

Dependencies

Requires libpam-dev package. Check the correct name for your distribution

Building

Run:

gcc -fPIC -fno-stack-protector -c src/main.c

to compile the module and then

sudo ld -x --shared -o /lib/x86_64-linux-gnu/security/pam_example.so main.o

to create the shared object and install it under /lib/x86_64-linux-gnu/security/.

Check that this folder is the correct pam modules folder for your system.
