Hi all,

By incident I removed the pam.d directory containing all pam modules from command line. Is there a way to recover the removed directory? any help is appreciated since I can't login to my computer without live cd anymore.

Unless you have some amazing recovery tools to had (most people don't)
you can't easily recover those files.

pam.d isn't put there by a single package, everything that uses pam is
liable to write it's own custom file there. You can regain your ability
to log in by remerging these packages:

sys-apps/shadow
sys-auth/pambase

To do that, you will need to boot off a livecd and chroot. Then a
reboot should see you fine. Then you could rememrge everything that has
pam in USE and hope this is enough.

Or, you could restore from backups. You *do* have backups of /etc,
right?

Also, qcheck from portage-utils can list out all packages that are missing 
files from /etc/pam.d, so you can know which packages need remerging.  Run 
"qcheck --all" and look for "AFK: /etc/pam.d/....." in the output.

HTH,
