hi there...im writing a pam module with encryption using gpg.
im trying to use popen() to run external command like gpg.
FILE *fp
fp = popen("sudo gpg -ear....", "r");
the problem is, im trying to run this with the sudo command
but the pam module won't accept it,
the error is
sudo: gpg: commant not found
please help i really need to run gpg with sudo
gpg is a bad example; it's much more paranoid about the (E)UID and (E)GID it runs under. I don't think sudo will go quite far enough.
Check the command you're trying to run manually; run it as root, as a "full" regular user, and as a restricted user like nobody. You'll probably have to do some additional (E)UID/(E)GID tweaking to get your module running as the correct UID/GID for what you want to accomplish.
