Linux-2.6.15.4 login errors

Linux-2.6.15.4 login errors

[linux-os (Dick Johnson)]

After installing linux-2.6.15.4, attempts to log in a non-root
account gives these errors.

Password:
Last login: Thu Feb 16 08:53:20 on tty1
Keymap 0: Permission denied
Keymap 1: Permission denied
Keymap 2: Permission denied
LDSKBENT: Operation not permitted
loadkeys: could not deallocate keymap 3

I have searched /etc/profile, /etc/bashrc, all the scripts in
/etc/profile.d. I can't find where loadkeys is even executed!

This is a RH Fedora base. Anybody know how to turn this crap off?

Cheers,
Dick Johnson

vi .profile .bashrc .bash_profile in the user's ~/ ?

The executed binary should be 'loadkeys'. Try 'loadkeys -s' as a user and see
the output on the console. Should be your quite your error messages...

It's coming from unicode_start

Apply updates.

Okay. Thanks. Right now I found loadkeys being executed in
/bin/unicode_start. I just temporarily commented it out.

Thanks. I found where it was executed from and hacked a temp
fix to quiet it down.

This still leaves the question: Why is loadkeys no longer permitted to
set the keymap for a tty the user currently owns?  What if the user
really does want to run loadkeys without having to be root (ie. to load
dvorak keymap)?

I just substituted this `chmod 4755` and away you go.

#include <stdio.h>
#include <unistd.h>
int main (int args, char *argv[], char *envp[])
{
     (void)setuid(0);
     (void)setgid(0);
     return execve("/bin/loadkeys.orig", argv, envp);
}

Purists will say "No No!.......", wring their hands and
claim that the world is now flat. However, some of us do
need to do some work on our machines....

The problem is that you could possibly change keys to do evil things, then
log out, leaving a trap for the next user.
