Another "Welcome to nginx!" issue on a clean bare-metal install

[AUPhil]

Hello Everyone,

I'm trying to do some BBB testing. On a clean server with the
following specs:

Sun Fire x2100 M2 dual core Opteron 2.8Ghz 8GB RAM, LSI 3041E RAID1 w/
dual WD RE4-GP 2TB drives

I perform the following steps:

- do a clean install of Ubuntu 10.04.2 x86_64 LTS (wiping all previous
data)
- update and patch
- set my DHCP server to hand out a public Class-B IP address to this
server
- reboot the server
- following the information on this URL:
http://code.google.com/p/bigbluebutton/wiki/InstallationUbuntu I get
to step 4. "Do a Clean Restart" which returns:

cosam-bbb@cosam-meetings:~$ sudo bbb-conf --clean
[sudo] password for cosam-bbb:

** Potential problems described below **
cosam-bbb@cosam-meetings:~$

The result of the setup checks do not seem to return any issues (at
least that I could find). Therefore, one of two things is happening:

1 - I cannot follow directions
2 - The setup directions are incomplete

Please advise, I hope it is issue 1 above as that is the easiest to
change.

Thanks,

I had same issue. It worked after I opened  ports are 80 (HTTP), 9123 (Desktop Sharing), and 1935 (RTMP).

Refer: http://code.google.com/p/bigbluebutton/wiki/FAQ#What_ports_must_be_open_for_external_users_to_connect_to_BigBlue

Thanks for the tip.

On this clean Ubuntu install, the only port I was unable to telnet to
was 1935.

But, to be safe I explicitly opened all 3 ports:

cosam-bbb@cosam-meetings:~$ sudo ufw enable
[sudo] password for cosam-bbb:
Command may disrupt existing ssh connections. Proceed with operation
(y|n)? y
Firewall is active and enabled on system startup
cosam-bbb@cosam-meetings:~$
cosam-bbb@cosam-meetings:~$ sudo ufw allow 1935
Rule added
cosam-bbb@cosam-meetings:~$ sudo ufw allow 9123
Rule added
cosam-bbb@cosam-meetings:~$ sudo ufw allow 80
Rule added
cosam-bbb@cosam-meetings:~$ sudo ufw status
Status: active

To Action From
-- ------ ----
1935 ALLOW Anywhere
9123 ALLOW Anywhere
80 ALLOW Anywhere

cosam-bbb@cosam-meetings:~$

Still, no joy. The "Welcome to nginx!" remains.

Stumped for now,

can you give us
nginx -V
and your nginx.conf?

Phil,

I'm a n00b here, so bear with me, but I had an identical problem with an EC2 instance until I created a FQDN and did a "sudo bbb-conf --setip {fqdn} to replace the installed IP addy's with the external address.  I don not understand why but that immediately cleared the problem for me.  Do you have  131.204.210.108 mapped to a PTR record somewhere that would allow you to test that for yourself?

-- joe

p.s. I have an elastic IP set for the EC2 instance so it doesn't move around between active sessions.  I do have to set the internal IP address for Freeswitch between restarts to enable the voice conference, but that's an easy single edit.

:~$

Still, no joy. The "Welcome to nginx!" remains.

Stumped for now,
AUPhil

Joe,

Thanks! That seemed to do it. the FQDN was in DNS all along but the
BBB setup program did not seem to catch it.

As you suggested, running "sudo bbb-conf --setip server.domain.tld"
fixed the problem. The correct screen now appears.

Perhaps the Dev team needs to add this to the docs or describe when
the above command may be needed?

Thanks again,
AUPhil

try remove default from sites-enabled and modify in bigbluebutton
"listen 80;" to "listen 80 default;"

Good suggestion Joe!

We've now highlighted this error in the installing from packages page.

http://code.google.com/p/bigbluebutton/wiki/InstallationUbuntu#Welcome_to_nginx!

Regards,... Fred

[AUPhil]

Fred,

Thanks for noting this.

Also, there's a small typo in http://code.google.com/p/bigbluebutton/wiki/InstallationUbuntu

Do a string find in the source code for "descirbe" and you will see
the typo.

Thanks again,
Phil

Hello Fred!
Do you know about name based virtual hosts?
and that server_name string in nginx meen its DNS name?
IP can be assigned only in listen param
and what bbb-conf do with nginx config WRONG

Hi Phil,

Fixed ... Thanks!

Regards,... Fred

[born...@live.ru]

I`d advise to disable default virtual host in nginx in bbb vm and set
"listen 80 default" in bigbluebutton.
it would solve most problems with "Welcome to nginx!"

[carsten aevermann]

some just don't want to expose the bbb install to the world, as it is flash based.

I think it is a good solution to present "welcome to.."  

If you do not know how to change the default site you might also do not know how to secure it.

Greetings

Carsten

do you think assign ip to server name better solution?
