Hi All,
I am getting an irritating problem on my Linux card (running selinux in permissive mode), that I didn’t use to see before, and am not sure whats causing it :
When I reset my Linux Card, once it boots up, and I get the login prompt, my first attempt at logging in as root on the console, ALWAYS fails ! My second attempt and afterwards ALWAYS succeeds !
unknown host login: root
password: root
Login Failure
unknown host login: root
Password: root
root@unknown host#
This didn’t used to happen before, and I am not sure what's causing it. I do know that if I disable selinux, the problem goes away ! I am guessing the problem is somewhere in between PAM and SELinux. Any suggestions on what may be causing it ? I have versions:
checkpolicy 1.34.1
libselinux 1.34.7
libsemanage 1.10.3
libsepol 1.16.1
policycoreutils 1.34.6
