Limit number of login at same time

[karthiknarayan]

I need to limit the number of login a user can do at the same time on a machine.

For example the user john can have only 3 logins to the server at the same time

how to do that???????

Hi karthiknarayan,

HPUX:

Modify file /etc/security/defaults

NUMBER_OF_LOGINS_ALLOWED
This parameter controls the number of simultaneous
logins allowed per user. This is applicable only for
non-root users.

NUMBER_OF_LOGINS_ALLOWED=0 Any number of logins are
allowed per user.

NUMBER_OF_LOGINS_ALLOWED=N N number of logins are
allowed per user.

Default value: NUMBER_OF_LOGINS_ALLOWED=0

man security

Hi,

You can set the max number of logins per user in the /etc/default/security file.
--
# Maximum number of logins per user. NOTE: This
# parameter only applies to the applications that
# use session management services provided by
# pam_hpsec(5) as configured in /etc/pam.conf, or
# those services that indirectly invoke the
# login(1) command.
NUMBER_OF_LOGINS_ALLOWED=3

Hello,

Use the /etc/default/security file to control logins and password restrictions.

PASSWORD_MIN_UPPER_CASE_CHARS=2
PASSWORD_MIN_LOWER_CASE_CHARS=2
PASSWORD_MIN_DIGIT_CHARS=2
PASSWORD_MIN_SPECIAL_CHARS=2
PASSWORD_HISTORY_DEPTH=10
MIN_PASSWORD_LENGTH=9

Hi,

You can edit .profile file for appropriate user and ad at the end of file:

[[ `who | grep john | wc -l ` -gt 3 ]] && exit

Shalom,

I recommend Boris' code be put in /etc/profile for all users. You will need to modify it to exempt system users and application owners like Oracle.

I like better the proposed solutions using defaults.

It's going to depend on the OS. If 11.0, it's *may* require patches if they aren't already installed.

you would need PHCO_16127, PHC0_24083, and PHCO_24390. as this is an old list, they have probably been superceded.
