Restrict the access to hpux system

[Jorge Prado T._1]

Hi,
S.O. HP-UX 11i
In order to restrict the access to the system in temporary form, can be changed to the file passwd? And to return to normality, to restitute the original file of passwd?

Thank in advance

Sure, that is one way to do it.

Make a copy of /etc/passwd. Remove the users you don't want to login. Then when they can log in again, copy the original /etc/passwd back into place.

I modified /etc/profile to look to see if file /tmp/nologin exists and if it does, it exits with a message the system is not available. Then if I want to prevent users from logging in, I enter "touch /tmp/nologin"

Put this in your /etc/default/security file
## Non-root users cannot login if /etc/nologin exists - displays contents
NOLOGIN=1

If the /etc/nologin file exists, it's content is printed on the screen and login is denied

From man security:

NOLOGIN This parameter controls whether non-root login can be disabled by the /etc/nologin file.

NOLOGIN=0 Ignore the /etc/nologin file and do not exit if the /etc/nologin file exists.

NOLOGIN=1 Display the contents of the /etc/nologin file and exit if the /etc/nologin file exists.

Default value: NOLOGIN=0
