 one correction: there is 2GB of ram, not 4GB

Hi Marboh,

Did you get any errors on the install?

>  one correction: there is 2GB of ram, not 4GB

Can you setup BigBlueButton in 4GB of memory?

With only 2GB of memory its very likely that one of the processes for BigBlueButton is not running and causing the create/join calls from the demo page to fail.

Regards,... Fred

Thanks to Fred Dixon my BigBlueButton is working as intended, there was some problem with demo app - maybe because i did have only 2GB of ram when i was installing it.

Anyway, thanks for help :)

hi marboh.

i have a question... 

how to change your ip address?

just sudo bbb-conf --setip command??

or more ? 

thank you

[Fred Dixon]

Hi 김동웅,

In the future, please post new questions in a new thread.  On an unmodified install of BigBlueButton, you can change the IP address with the following command

   http://docs.bigbluebutton.org/install/bbb-conf.html#setip-lt-hostname_or_ip-gt
