konkretniej proszę, czy chodzi tylko o komendę reboot, czy kombinację ALT+CTRL+DEL ?

nie jestem pewien jak to jest z chmod/chown i sudo, wiem ze aby pozbyc sie ctrl+alt+del ale tak dla wszystkich:) wystarczy w zdaje sie /etc/inittab zmienic linijke:
| Code: |
# What to do at the "Three Finger Salute".
ca:12345:ctrlaltdel:/sbin/shutdown -r now
|
i zmienic /sbin/shutdown na np /dev/null czy cos w ten desen

Możesz | Code: | # What to do at the "Three Finger Salute".
ca:12345:ctrlaltdel:/sbin/shutdown -r now |
zmienić na jakiś swój skrypcik np.: | Code: | # What to do at the "Three Finger Salute".
ca:12345:ctrlaltdel:/sbin/skrypcik.sh |
.
W 'skrypcik.sh' możesz napisać: | Code: | #!/bin/sh
shutdown -r now |
i dać skrypcikowi bit SUID albo dopisać linijkę w sudo... |

Sorcia ale linux ignoruje bit SUID dla skryprów.

No to można napisać prościutki programik w C : | Code: | int main(void) {
exec('shutdown -r now');
return 0;
} |
P.S. Jeśli ignoruje bit SUID to zawsze jest sudo... Zresztą to nawet jest bardziej eleganckie rozwiązanie... |
