Security setting in HPUX

[Clement Yeo]

Hi all,
like to find out how to restrict user from concurrently login to more then 1 terminal.

Tried setting in "/etc/default/security" with parms "NUMBER_OF_LOGINS_ALLOWED=1" but did not work.

Please help!!

In the .profile add the line

who -u |grep $USER && exit 0

Hi,

The option to use securify file is not available for 10.20 and by default on 11.0 but is available by default on 11i. For 11.0 systems, you will need to install a patch.

I suggest you install the latest available 'login' patch.

Go to itrc web site and search for login in the patches URL.

Hi (Again),

One crude way of checking to see if your system allows the use of /etc/default/security is to do

$strings /usr/bin/login |grep -i number_of_logins_allowed

and see if it displays this string.

Yes, the string appears. What next?

Edit/create the following line

NUMBER_OF_LOGINS_ALLOWED=1

in the file /etc/default/security

owner & group=bin.

Sorry I've forgot to mention that it only work for telnet session but not for those sessions by ssh. How??

[Sanjay Kumar Suri]

NUMBER_OF_LOGINS_ALLOWED is applicable only for non-root users and only for services which use the "login" binary for authentication.

The latest version of SSH is supposed to honor settings in /etc/dfault/security. What version of ssh are you running? Current release is A.03.71.000.

Hi,

By default "useLogin" feature of sshd would be off. So, edit sshd_config file and enable that option and restart your sshd process.
