Login simultaneously

O'lnes — Thu, 26 Sep 2002 07:35:42 GMT

Our system only allow user to login one session, ( don't accept one uid login simultaneously ) , so if the user's login session was dead then this user can't login again until it is timeout, can someone suggest how to let the user to login when the previously login was dead? Thanks.

Hi,
At which condition you call a user as dead ?
If is is idle time then a scripts can be writen to run in cron to kill that user after certain hours.

In AIX I have come across limiting the login session in the /etc/security/login.cfg or something,
in which number of logins is limited.

I am sure whether HP has a kind of feature,but I could not see anything with the non-trusted system.

Probably you can check your /etc/profile where there is something which restricts the user to a single login.

Thanks

Hi animesh chakraborty,

1.I carify the dead process is when the tty is ??? ? ???
2.Can't use script cos it is not secure , it might kill some sleep jobs, and the user need to wait for long time.

Hi T G Manikandan ,

I have control the user to login not more than one session, but now I want to let them login again when the previously one is dead.

Hi,

You don't say which version of HP-UX you're using, but here's a couple of possibilities:

* check if anyone has scripted something into /etc/profile that checks for duplicate UIDs

* If you're running 11 or 11i then check the /etc/default/security file for a line containing NUMBER_OF_LOGINS_ALLOWED. This functionality is only documented at 11i in security(4), but is available at 11 if you have the login patch PHCO_16309 (or a later version.)

Please also see knowledge database document KBRC00008090 for further info.

regards,

Darren.

/etc/security is only in 11i

if you have 11.0 you can't use it

hi Joaquin Gil de Vergara Q ,

I think the link is not related to my question.
I just want to let the user kill the previous dead process. Thanks.
