 |
|
Hi,
As I was installing my Yubikey's I modified /etc/pam.d/sudo to require a key. Something upset the machine, and even after having restored the file to what I believe is stock
| Code: | auth substack system-auth
account substack system-auth
session substack system-auth
|
it refuses to give me a password prompt! It just prints "Sorry, try again." three times and quit.
It's my own doing, I was trying to require a valid password before initiating the key, but it did not work out so well, and hm, restore didn't either really...
I could try rebooting, but...

This feel like pam_faillock at work. you can try command "faillock" as root, if you see your login ID listed. Then try | Code: | | faillock --user <your username> --reset |
should be able to reset the lock condition. and Sudo should then. |

Spot on! I tried 'faillock' as root and didn't see anything other than what looks like headings for my user + gdm. I ran the reset command anyways, and well, now it works again!
Thank you so much!  |
