Hi Noriot,

You can find the security salt defined in the bigbluebutton.properties file. Here's a link to the docs.

http://bit.ly/drSra2

Your are looking for the following name/value pair in bigbluebutton.properties.

beans.dynamicConferenceService.securitySalt=5e5ff0968546b8aaacce0462a99bca30

Your API calls must use the same securitySalt as the above. To change the security salt, you can use bbb-conf

sudo bbb-conf --salt new_security_salt

which changes both the salt in bigbluebutton.properties and bbb_api_conf.jsp (built-in API demos).

Regards,... Fred

Hi Noriot,

There is a file that needs to be configured to whatever you set your bbb-conf setip to. Your bbb_api_conf.jsp file should look something like this:

<%!

// This is the security salt that must match the value set in the BigBlueButton server

String salt = "1bunch of random charactersgenerated by bbb";

// This is the URL for the BigBlueButton server

String BigBlueButtonURL = "set this to the same URL used in the bbb-conf setip command ";

%>

Hope that helps.

Hi there,

Sorry, didn't work. I gave up this stupid system.

Using private IP address(like 192.168.1.32), it works fine.
But using global IP or domain name, it doesn't work.
(java.lang.NullPointerException)
So security salt seems to be irrelevant in this case, I suppose.

Please anyone helps me!

Hi Norit,

> at org.apache.jsp.demo.demo1_jsp.getJoinURL(demo1_jsp.java:168)

Can you check the contents of

/var/lib/tomcat6/webapps/bigbluebutton/demo/bbb_api_conf.jsp

It should look something like

<%!

// This is the security salt that must match the value set in the BigBlueButton server

String salt = "asfasfdaew234sadf23awefr";

// This is the URL for the BigBlueButton server

String BigBlueButtonURL = "http://192.168.0.173/bigbluebutton/";

%>

I'll be the problem is the BigBlueButtonURL -- can you check it on your end.

When you get this JSP error, it usually means that the HTTP request failed, and the HTTP request is based on building a URL using the value of BigBlueButtonURL.

Regards,... Fred

And this is VirtualBox Virtual Machine, easy to erase. Assigned port
number is 8888.

I thought my error is as same as John's.

But "at org.apache.jsp.demo.demo1_jsp.getJoinURL(demo1_jsp.java:168)
etc."
means the errors are a little different than John's, aren't they?

Hmm.

Hi Noriot,

I just tried changing the port number on one of our test servers. using the bbb-conf command so it listens on port 8888.

firstuser@ubuntu:~$ sudo bbb-conf --setip 192.168.0.169:8888

[sudo] password for firstuser:

firstuser@ubuntu:~$

I then tried accessing BigBlueButton through

http://192.168.0.169:8888/

and it worked. So, something is different with your setup. Did you edit any configuration files by hand?

Can you try the command

sudo bbb-conf --setip 183.77.125.184:8888

And try accessing your server again.

Hi Fred,

But we can't access through internet, from outside of your LAN.
That is your private IP address.

Again, using private IP address, it works fine all the time.

Hi Noriot,

OK, so we're now in the area of ensuring your host computer and portforwarding and firewall are configured correctly. I tried the parameters you sent, and I can make a valid API call from our location

http://183.77.125.184:8888/bigbluebutton/api/getMeetings?random=1961&checksum=410b9db67a089213631c2fdeefa6e62c3a524545

This gives me a valid response. The problem *must* be within the server making the HTTP request to the API. Here, as shown above, my machine knows how to access 183.77.125.184. But when you use the demo1.jsp example on the server, the Java Servlet is making a request to 183.77.125.184.

In other words, on your internal server, does it know how to reach itself using the external IP address? You can check this out using the command

wget "http://183.77.125.184:8888/bigbluebutton/api/getMeetings?random=1961&checksum=410b9db67a089213631c2fdeefa6e62c3a524545" -O -

Here's what I get

firstuser@bbb-vm-20100120-15:/tmp$ wget "http://183.77.125.184:8888/bigbluebutton/api/getMeetings?random=1961&checksum=410b9db67a089213631c2fdeefa6e62c3a524545" -O-

If the HTTP request fails on your server, then we're getting close to the problem.

Hi Fred,

Private IP makes system work fine. But Global IP doesn't
(java.lang.NullPointerException) in my circumstances.

Both of them display site contents except BBB main system.
http://183.77.125.184:8888

What's the difference in the system (or in my circumstances)?

>The problem *must* be within the server making the HTTP request to the API.

Maybe you're right in this point.

But how can we do setting about it?

Hi Noriot,

This is a networking configuration issue with your server. For some reason, its unable access itself through its own public IP address.

Obviously, we don't have any visibility into the networking configuration of your server.

Are you doing this a company or on your own server? Is there someone on your end who can help you figure out how to configure your VPS server so it can access itself through its public IP address?

Regards,... Fred

Hi Fred,

This is my own server. VirtualBox virtual machine, ubuntu 10.04 64bit
OS server. Host server is ubuntu 9.10 64bit.

And domain name asigned to private IP doesn't work, just the same
error.
Can you explain this phenomenon?

For example, edit hosts file,
192.168.1.32 myccs.com
(Asigned port number 80 this time)

Using myccs.com instead of 192.168.1.32, it doesn't work, just the
same error. (While setting and using private IP 192.168.1.32, it works
perfect.)
Of course I did bbb-conf --setip myccs.com etc. properly maybe.
It displays top page and other links, but except BBB main system.

I don't know why.
I'm a Japanese. We use character code Shift-jis other than utf-8.
Isn't it relevant in this error?

Anyway I think I need to take more time to figure out. And I'll put
your point in my mind. (so it can access itself through its public IP
address?)

Thanks a lot, Fred.

Hi Fred,

I got it! Finally I got through, succeeded.

Thank you very much for your suggestion, Fred.

http://skd.ath.cx:8888

This Virtual Box server will be erased soon, and I will set up another
one, though.

Thanks anyway!
