Operating Systems Solaris stay in multi user mode but stop logins to system? Post 302289445 by NewSolarisAdmin on Thursday 19th of February 2009 03:12:58 PM
Old 02-19-2009
BTW what will that do to active logins? I mean if I were to do it now would it kill existing ones, or just stop new ones?

And just to clarify I will still be able to get to the system over the serial cable interface using putty from another box right? Just want to be sure as the direct login via the kvm switch directly connected to the box is messed up right now. Wouldn't want to shoot myself in the foot there if you know what I mean...

nologin

NOLOGIN(5)						      BSD File Formats Manual							NOLOGIN(5)

NAME

     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.

FILES

     /var/run/nologin  default location of nologin

SEE ALSO

     login(1), login.conf(5), pam.conf(5), rc.conf(5), nologin(8), pam_nologin(8), shutdown(8)
