Hi,
I have a class of approximately 30 students that needs to login in moodle at the same time with the same ip-adress.
Unfortunately not everyone is able to log in. When I look into logs I see that they ahve loggin in successfully, but the student itself can't. They enter password and then tehy come back to the same login screen.
Is there maybe some configuration setting about the maxximum number of logins with same ip-adress that needs to be set?
No two people can log in from the same IP Address at the same time. I suspect you you have a network problem if you are trying to do so. For a network to work, every computer must have its own address on the network. At the same time, each computer must have its own name and each student must have their own account.
Try runing IPCONFIG at the command prompt and check the IP details of each computer.
Stephen, that is not quite right. Their requests might, for example, be processed via an HTTP proxy server, so that from the point of view of the Moodle server, all requests come from the same IP address.
Moodle may show them as coming from the same IP (All my external users show as coming from the same IP which is an upstream firewall) but that it just NAT doing its job. If the machines have the same IP on the same network it will not work.
In a local LAN situation all computers should show with their own and individual IP.
These are not Moodle restrictions. They are IP network protocol restrictions. If everything else (network wise) is working then I suspect that the computers do not have the same IP and that the problem is somewhere else.
I don't know about on a Linux workstation, but on a Windows machine I can not have two different logins to Moodle at the same time. As soon as I open a new browser and point to Moodle.org it identifies the cookie from the first session and shows me as logged in. Logging out in either one also causes all sessions on that computer to log out (may need a refresh to show).
I think Ben has it right. AV software or an overstrict settings on the browser is the most likely cause. Some AV programs will stop the loading of cookies which will stop access to Moodle. This is the first thing I would look at.
Hellen, either way, I hope our comments help will finding a solution to your problems.
I work with Moodle all the time and I frequently log into the same site from two or three different browsers on my Windows workstation. This allows me to be different people at the same time, such as teacher and student. When logged in with both Firefox and Explorer, for example, I can even demonstrate chat to people by chatting with myself. I have never had any problems with collisions.
It is not, possible, however, to log into Moodle as two different people from the same browser.
Yes, different browsers will handle the cookie independently and work independent of each other. This will help the technical people and those who like to play with Moodle. The average student will click on the icon on the desktop and has no knowledge of which browser they are using. The average school computer will not have more than one browser installed.
Will this help Hellen identify her problem?
Hi,
If they come back to the login screen and there is NOT a note about invalid login, you most likely have security set too high on the browser and Moodle is not able to set a session cookie.
The obvious way to test this is to move the user who cannot log in to the computer of a user who can log in, close the browser, reopen the browser, and attempt to login.
Hi everyone,
Thank you all for your suggestions. I will continue investigating with the tips I got here. If the solution is found I will definitely post it here.
