dimdim web meeting

Hello

I would like to know is there a process for changing the new CentOS virtual machine default port from port 80 to 8080 or really any port other then 80? I changed to 8080 and had it working but it then broke the desktop sharing. Is there a process to change the port and NOT break the desktop sharing?

Thanks

Hello,

Please follow the exact steps as mentioned below to make the changes for port and let me know if you are facing with any issues.

Note that you cannot use ports 8080 / 9090 / 1935 / 8088 / 4000 / 8100 as these ports are used by Dimdim Components.

Follow the instructions carefully and change only the files / lines provided below:

1. Open lighttpd.conf located under /usr/local/dimdim/Mediaserver/mods/

vi /usr/local/dimdim/Mediaserver/mods/lighttpd.conf and

change the following from

## bind to port (default: 80)
server.port = 80

to

## bind to port (default: 80)
server.port = YOUR_AVAILABLE_PORT

2. Open dimdim.properties located under /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/

vi /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/dimdim.properties

change the following from

a.
dimdim.serverPortNumber=80

to

dimdim.serverPortNumber=YOUR_AVAILABLE_PORT

b.
dimdim.dmsServerAddress=SERVER_ADDRESS:80

to

dimdim.dmsServerAddress=SERVER_ADDRESS:YOUR_AVAILABLE_PORT


c.
dimdim.dmsServerInternalAddress=localhost:80

to

dimdim.dmsServerInternalAddress=localhost:YOUR_AVAILABLE_PORT


3. Open streaming.properties located under /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/

vi /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/streaming.properties

change the following from

streaming_server.2.rtmp_url=http://SERVER_ADDRESS/screenshare/
streaming_server.2.rtmpt_url=http://SERVER_ADDRESS/screenshare/
streaming_server.2.max_number_of_streams=-1
streaming_server.2.supported_stream_types=DTP

to

streaming_server.2.rtmp_url=http://SERVER_ADDRESS:YOUR_AVAILABLE_PORT/screenshare/
streaming_server.2.rtmpt_url=http://SERVER_ADDRESS:YOUR_AVAILABLE_PORT/screenshare/
streaming_server.2.max_number_of_streams=-1
streaming_server.2.supported_stream_types=DTP

Thank you...i have made the changes replacing port 80 with port 8000 and it seems to work fine internally...But when i hit it externally i get the login page...i start a meeting then the center screen comes up page cant be displayed and the audio connection fails.

Im allowing port 8000 and 1935 through my firewall. I do not see any drops/denies in the firewall logs

Any ideas?

Thanks

Hi,

Thanks for the updates. Could you please let me know the outputs for the following for the Dimdim server machine:

1. status of Dimdim components from Dimdim Admin Console
2. ps -aef | grep python
3. ps -aef | grep red5
4. telnet to port 1935 from the machine where you are trying to start the meeting.

Regards,
-Rajesh

Rajesh

I can connect to port 1935 through the firewall no problem...

Here is the output you asked for


[root@localhost ~]# ps -aef | grep python
root 1654 1652 0 May21 ? 00:00:00 python /sbin/audispd
root 2037 1 0 May21 ? 00:00:00 /usr/bin/python /usr/bin/zdaemon -S schema.xml -b 10 -s zdsock -m 022 -x 0,2 python /usr/local/dimdim/Mediaserver/mods/interface.py

root 23105 22421 0 03:24 pts/0 00:00:00 grep red5
[root@localhost ~]#

Thanks

Rajesh

Also to add, the desktop sharing doesnt work internally either. But everything else seems to function OK...the audio works all the screens come up....but again externally the audio doesnt work, sharing doesnt work...and the mainscreen says page cant be displayed

thanks for your help!

Hi,

Could you please let me know if the external address and internal address for accessing the machine (where Dimdim server installed) is different?

If so please login to the Dimdim Admin Console, change the ip address to external ip address and restart Dimdim Server. By this way you will be able to access Dimdim from outside.

They are on the same box for internal an external

Hi,


Could you please drop me the wrapper.log available under /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/logs/?

Hi,

Could you please email me the files that you have modified for port along with wrapper.log?

Rajesh

I have emailed you the files

Thanks

Shaun

Hi Shaun,

I received your files. I will check and let you know the updates.

Regards,

rajesh@dimdim.com

Hi Shaun,

From the initial look up of the files that you have sent,

In dimdim.properties, the port for the following is not changed to 8000

Snippet:
dimdim.dmsServerAddress=***********:80
dimdim.dmsServerInternalAddress=localhost:80

This should be :
dimdim.dmsServerAddress=***********:8000
dimdim.dmsServerInternalAddress=localhost:8000


If you are changing the ports, please follow the above instructions carefully and change the ports.

Regards,
-Rajesh
rajesh@dimdim.com

Hi Shaun,

Similarly in streaming.properties.

Snippet:
streaming_server.2.rtmp_url=http://**************/screenshare/
streaming_server.2.rtmpt_url=http://*************/screenshare/

This shd be:
streaming_server.2.rtmp_url=http://**************:8000/screenshare/
streaming_server.2.rtmpt_url=http://*************:8000/screenshare/

After these changes, restart the Dimdim server and let me know the updates.

Rajesh,

All works internally just fine...when i access it from the external side...i can log in, but get page cant be displayed on the spalsh page...and it never asks me if i want to share desktop or white board or presentation...

I verified nothing is being blocked by the firewall...there are no drops everything is permitted.

Thanks

Shaun

Hi Shaun,

I did that...the splash screen now comes up...however i still get connection failed for audio and desktop sharing...

Any ideas

Thanks

hi,
probably this help give you a solution...
i made this and now it works :

- vi /usr/local/dimdim/Mediaserver/mods/lighttpd.conf and leave port 80 not 81

then

vi /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/dimdim.properties

dimdim.ServerAddress=SERVER_ADDRESS
dimdim.serverPortNumber=81
dimdim.dmsServerAddress=SERVER_ADDRESS:81
dimdim.dmsServerInternalAddress=localhost:81

then
- vi /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/streaming.properties

and modifiy port from 80 to 81

streaming_server.2.rtmp_url=http://SERVER_ADDRESS:81/screenshare/
streaming_server.2.rtmpt_url=http://SERVER_ADDRESS:81/screenshare/
streaming_server.2.max_number_of_streams=-1
streaming_server.2.supported_stream_types=DTP

locate server.xml and modify port on 81

restart dimdim and go to http://SERVER_ADDRESS:81/dimdim
* NOTE if made this cherrypy dont give error for / at final...

Control port 443 and 1935
The dimdim start well

sandro

i dont want my dimdim to run on 81 thought i want it to run on 8000....what you have listed is the same thing Rajesh had me do (except the server.xml file)...

currently its working with port 8000...except externally i cant get audio or desktop sharing to work

Thanks

Rajesh

Any ideas here as to why my desktop sharing and audio doesnt work externally?

Thanks

Shaun

Hi Shaun,

Is your internal and external ip addresses different? If so, please go to Dimdim Admin Console, change the ip address to external ip address and restart Dimdim.

Please let me know if this solves your problem.
