Hi J,
Well, if you have an active users table with a users name in it and you check when logging in to see if that users name is in that table, They can not log in again. No matter what machine or browser they are in.

As far as another user logging in on that same machine, you could match a cookie on the machine and the database that holds what browser they are using and username, an MD5 ip, etc. But someone can always delete cookies and some even know how to bounce ip addresses, so unless you have a bunch of hackers using your machines, these suggestions should work.
Unless someone else has a better suggestion.
GL,

:)

I want that only single user can login on a single machine.... If User has logged in one browser he should not login through 2nd browser...

And no other user should login on same machine in any browser

in Simple words:

MAXIMUM ONE USER SHOULD LOGIN IN ONE MACHINE.......

You lost me on that one.

You want it so that multiple users can log in, but they have to be on separate browsers?

Hi,

yes, I can make a databse table to record LOGIN details, But I want that No
other user can login on same machine on smae or another browser.

E.g.

If user1 has logged in from IE then user2 should not login from Firefox or
Chrome etc..

I need ONLY ONE USER ACCESS AT SAME TIME ON SAME MACHINE (On Same or Other
broswers)

Regards

Hi All!

I am looking for a solution, I want a user to do a single Login only on
a
PC
.

E.g. If a User has logged on my website website.com in Internet
explorer,
then he cant login on same website in another browser like Firefox etc
with
same loginid or another.

Can I trace MAC address of a single machine to solve this issue?

The browser IP address works for us quite reliably. Once logged in, you
get
a message saying already logged on ... and where ... but it does need a little help if the user closes the browser without logging out. One needs
a
facility to 'bounce' a user now and again .... however some remote users
may
well have 'floating' IP addresses :(


Don't rely on IP addresses staying the same for a user, it's not safe
in any way and not needed anyway. Karls method is probably the best
bet - just remember to record "last accessed time" so anyone not
accessing for more than 15-20 minutes will succeed if trying to log in
again.

Regards
Peter
