Has anyone linked their moodle to google apps using the google authentication plugin?

[reggiep]

I have installed the plugin from moodlerooms but I keep gettings a connection error...

Google Apps error: Unable to Connect to ssl://www.google.com:443. Error #110: Connection timed out

 

My moodle is installed on ubuntu server and goes through the LA firewall so I am wondering if I can do any checks on the ubuntu box to see if it's something I need to change on it?

 

Has anyone else used this successfully?

 

Thanks

run nmap Google

 

it will then try to see if it can see that port.

 

our lea blocks port 443 by default and you have to use the upstream proxy.

[reggiep]

Thanks for that.

i ran it and got this

Starting Nmap 4.53 ( Insecure.Org - Nmap Free Security Scanner, Tools & Hacking resources ) at 2011-04-05 12:03 BST

Warning: Hostname Google resolves to 6 IPs. Using 209.85.147.103.

Note: Host seems down. If it is really up, but blocking our ping probes, try -PN

Nmap done: 1 IP address (0 hosts up) scanned in 2.031 seconds

 

Not sure what to make of it yet though!

[glennda]

It means that server cannot see google.com

 

do you have to use an upstream proxy with you la?

 

EIDT: try nmanp -PN http://www.google.com

 

it will then scan the ports rather then ping the host and then search.

Yes we have a proxy server that we have to go through!

I presume you need to either set the system proxy on the ubuntu machine (not sure if the google app will be happy with that though but never used it)

 

If not then you need to ask the lea to open up port 443 to that specific ip address i would presume but without know the full setup i'm not sure.

When I use nmap -PN Google I get no response, the command line stays blank.

I'm starting to think now that there is nothing wrong with my moodle install but something else is to blame?

can you actually ping Google

 

also check you default gateway is correct by running ifconfig

[reggiep]

I'm going to look at this further.

 

thanks

I got a response eventually!

pings seem to be blocked via our LA firewall.

 

My gateway seems fine.

We had to get the LEA to open up port 443 to Google for traffic from our webserver to get single sign-on to function in Moodle. We tried setting the proxy in Moodle and system wide on the server and neither worked.

It will almost certainly be a proxy issue. PHP Curl will need this setting otherwise it won't be able to pass through the proxy to authenticate with Google. Either that or as mentioned above, a system proxy may fix the issue - though I am no *nix expert.

[reggiep]

I can't find anywhere where you can globally set the proxy for cURL in ubuntu. I don't think it is possible.

try this Ubuntu Manpage: curl_easy_setopt - set options for a curl easy handle

 

go down to CURLOPT_PROXY

Thanks glennda,

I have found the page but it doesn't really help as I can't work out what it is telling me to edit!

I think you need to find a page in the google module (at a guess)

 

I'm just downloading the module to have a look.

[glennda]

I think this could be it

 

in the module/admin/config.php there is a section like this

define('GAPPS_PROXYHOST','my.proxy.server');

define('GAPPS_PROXYPORT','3128');

define('GAPPS_PROXYUSER','');

define('GAPPS_PROXYPASSWORD','');

 

try setting your upstream proxy there?

[reggiep]

I'm making myself look like an even bigger idiot now but whereabouts is that. I can't find the file that I need to edit!

 

Are these the files from the moodlerooms add on?

 

thanks

I think modules are in the web folder under mod?

 

then it will be under the folder name then in admin

 

this is the one i downloaded?

Ah! This could be why!

 

I am using the complete intergration for google apps from here..

 

Dev: Code Releases

 

This add on intergrates eveything and included SSO without adding any additional admin, of course that's once you can get the bleeding thing to go through a proxy!

[glennda]

Ahh i justs google google apps moodle and it came up.

 

I'll look through that and see if there is anything.

[glennda]

Open one of the file in the google4 folder in dreamweaver then do a search of the folder for proxy there is loads of references to them and a few for defining proxy set.

I have ammended a couple of files, pointing to our proxy. Thanks again for the help.

I think I need to get some firewall changes now.
