It seems that Moodle cannot connect to the LAMS server. Note that this is a server (Moodle) to server (LAMS) call.

Perhaps you can check if from your Moodle server you can make http calls to LAMS?

If you are in linux unix, you can do

telnet {your-lams-server-ip-here} {port-in-which-lams-is-running}

So if the ip for my LAMS server is: 137.111.246.78 and is running on port 8080, then I would go:

telnet 137.111.246.78 8080

Thanks,

Ernie,

Thank you for responding. I have installed LAMS on my laptop running Vista. I assume this is now acting as the LAMS Server? Additionally, I can open the LAMS Author. The problem is at the Moodle end (on a different server located on Bluehost provider) where I'm getting the LAMS failed error.

When I attempt to open LAMS Author from Moodle server I get:

http://98.154.99.120:8080/lams/LoginRequest?uid=anava&method=author&ts=August+31%2C2009+11%3A46+am&sid=sysadmin&hash=01f0c942ebe0af3699a5428237c4c5b1fc39c873&courseid=2&courseName=USH+8%2F2009&country=US&lang=en&customCSV=anava%2C2%2C2%2Csysadmin&requestSrc=moodle¬ifyCloseURL=http%3A//www.mylausd.com/znani/mod/lamstwo/view.php%3Fid%3D5

The 98.154.99.120 is the internet ip address of my LAN router. In my LAN, my laptop has an assigned address of 192.168.1.102.

Further, when I attempt to add a new lesson from Moodle, I get:

Call to LAMS failed: received no response or connection was refused. Please check that you have the correct LAMS server URL and that it is online.

How do I check from your Moodle server you can make http calls to LAMS?

...too many question...I appreciate your help.

Hi Aureliano,

Yes, once you installed LAMS you are running a LAMS server in your laptop.

Now if your laptops is behind a router, then you would need to ensure that your router forwards calls on the desire port to the 192.168.1.102 address. So this can be a bit tricky, but it's doable. Check in your router's manual for a feature call port forwarding (or just google it :-).

If you just want to test how Moodle and LAMS play together, have a look at the Moodle - LAMS demo site. You can sign up for an account there and see how it all works.

Animations on some of this features are available here:

  1. Authoring and Preview
  2. Enactment/Runtime and Monitoring
  3. Using Moodle Tool outputs for Branching
  4. Achieving interoperability using Export and Import

Let us know if you need any further help.

Thanks,

Ernie
