Hmm...I thought I sent an answer. The problem from the kernel's perspective is that it has no idea what user space is doing. It can't tell a password from anything else being typed. There is a flag that can be set for the TTY to hide characters. But the issue then becomes that now you have a loophole that a crafty admin could use to hide what he's really doing. If anyone has ideas on how to improve this, I think we should. -Steve > > On 10 Jul 2012, at 08:29, Florian Crouzat <[email protected]> wrote: > >> Hi, > >> > >> This is my first message to the list to please be indulgent, I might be > >> mixing concepts here between auditd, selinux and pam.
