nologin(4) File Formats nologin(4)NAME
nologin - message displayed to users attempting to log on in the process of a system shutdown
SYNOPSIS
/etc/nologin
DESCRIPTION
The /etc/nologin file contains the message displayed to users attempting to log on to a machine in the process of being shutdown. After
displaying the contents of the nologin file, the login procedure terminates, preventing the user from logging onto the machine.
This procedure is preferable to terminating a user's session by shutdown shortly after the user has logged on.
Logins by super-user are not affected by this procedure.
The message contained in the nologin file is editable by super-user. A typical nologin file contains a message similar to:
NO LOGINS: System going down in 10 minutes.

nologin -- disallow logins
DESCRIPTION
Programs such as login(1) disallow logins if the nologin file exists. The programs display the contents of nologin to the user if possible
and interrupt the login sequence. This makes it simple to temporarily prevent incoming logins systemwide.
To disable logins on a per-account basis, investigate nologin(8).
SECURITY
The nologin file is ignored for user root by default.
IMPLEMENTATION NOTES
The nologin feature is implemented through login.conf(5), which allows to change the pathname of the file and to extend the list of users
exempt from temporary login restriction.
PAM-aware programs can be selectively configured to respect nologin using the pam_nologin(8) module via pam.conf(5).
The nologin file will be removed at system boot if it resides in /var/run and cleanvar_enable is set to ``YES'' in rc.conf(5), which is
default. Therefore system reboot can effectively re-enable logins.

I'm setting up a Solaris 10 box to run Lawson application, which needs users to have Unix acounts, but the users will not be using interactive shell. To make it more secure, I'd rather not give them a valid shell. I know there's a trick by putting /noshell in the /etc/passwd file, but the problem... (2 Replies)

Hi,
Need one clarification..
If suppose, I have disabled the login to a particular user XXX, but not deleted the user.
So the scripts which must be executed using the user XXX can still be executed using that user or is it not possible..?
In our tasks, we are disabling the user XXX, and after... (1 Reply)
Is it possible to SSH with an account that has its shell set to /sbin/nologin?
The reason I ask is because I am running an instance of nagios where I need to use SSH keys to run a check, but I am getting connect errors in Nagios. Also, what is the risk I run into if I just simply change my... (2 Replies)

In Solaris11 we have the option of making it a role because RBAC is enabled but... (1 Reply)
