Disable multiple ssh logins for an OS user in Solaris
Hi folks,
I am fairly a beginner when it comes to Solaris OS administration, but part of my job somehow has scope to provide L1-level of OS administration over a few solaris servers.

Now, we have a requirement to limit the number of simultaneous ssh logins/sessions to the server, sort of similar to a windows server where an OS windows account can only be used one at a time, so if another colleague logged in to that same windows server, my current RDP session will be cut off.

Is there any way to do the same for a solaris server? My servers are on SunOS 5.11 11.3 sun4v sparc.

I've done some googling and I see the files "/etc/limits" and "/etc/security/limits.conf" being mentioned but I don't have those in my server.

Any input from the community will be very much appreciated.

gnome-ssh-askpass

GNOME-SSH-ASKPASS(1)					      General Commands Manual					      GNOME-SSH-ASKPASS(1)

NAME

       gnome-ssh-askpass - prompts a user for a passphrase using GNOME

SYNOPSIS

       gnome-ssh-askpass

DESCRIPTION

       gnome-ssh-askpass  is  a GNOME-based passphrase dialog for use with OpenSSH.  It is intended to be called by the ssh-add(1) program and not
       invoked directly.  It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display
       is  available).	This happens automatically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro-
       grams, for example.

       In order to be called automatically by ssh-add, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass.

ENVIRONMENT VARIABLES

       The following environment variables are recognized:

       GNOME_SSH_ASKPASS_GRAB_SERVER
	      Causes gnome-ssh-askpass to grab the X server before asking for a passphrase.

       GNOME_SSH_ASKPASS_GRAB_POINTER
	      Causes gnome-ssh-askpass to grab the mouse pointer using gdk_pointer_grab() before asking for a passphrase.

       Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab().

       This manual page was written by Colin Watson <cjwatson@debian.org> for the Debian system (but may be used by others).  It was based on that
       for x11-ssh-askpass by Philip Hands.
