Hello,
I have install lams 2.3.4 on Ubuntu 9.04.
On lams-server (10.84.22.11:8180/lams) everything working perfect (i think.....)
On client i have problem. Open a browser typing
http//:10.84.22.11:8180/lams and DO NOT shows the GUI, only text, NO pictures, No icons.

When i make login on server and then logout:

Elias,

It sounds that this might be a network issue and not to do with the LAMS server.

Just to make sure can you ping the server from the client?
What's the IP in the client? Are they in the same network?


Thanks,

Ernie

The server ip is 10.84.22.11 and the client ip is 10.84.22.128
The client has Win XP Home SP3.
The outputs of ping, tracert, ipconfig from client to server are:

Just to be sure, you typed http://10.84.22.11:8180/lams instead of the one you put above, right?

Right! I get it now...

Ok, login into the server (on the server machine) as sysadmin. Go to the Sysadmin menu and then go to "Edit Configuration Settings". In there, look for the SERVER URL... I bet you it says: http://localhost:8180/lams/ right?

Change that to http://10.84.22.11:8180/lams/ and then check on the client machine... it should work then.

Yes, exactly as you say.
I change in "Edit Configuration Settings" the Server Url from http://localhost:8180/lams to http://10.84.22.11:8180/lams and work perfect in clients.
Congratulations, excellent, wonderful, yupiiiiiiiiiii!!!!!

THANKS a lot,
