IP does not match: IP from ifconfig bbb

[Tedbir]

I've installed bbb 08 on ubuntu 10.04. the installation went good.
the ip for bbb-server is: 192.168.0.13
as host: with bbb-conf --setip www.mybbb.edu
locally i.e. on the server i can access the bbb-windows with <www.mybbb.edu>
with the i.p <192.168.0.13> and localhost appears <welcome to nginx>
when i try from another machin in the same LAN i've access to the bbb-machine (server) only with the ip 192.168.0.13.
the host www.mybbb.edu launchs <server not found>
with with bbb-conf --clean i get Potential problems
IP does not match:
#                           IP from ifconfig: 192.168.0.13
#   /etc/nginx/sites-available/bigbluebutton: www.mybbb.edu
# Warning: The value (www.mybbb.edu) for playback_host in
# /usr/local/bigbluebutton/core/scripts/slides.yml
links bn. sites-available and sites-enabled are done.
i've no idea what to do.
any help?
thank you

for further clarification
IP configuration is done in /etc/hosts. 192.168.0.13 www.mybbb.edu. At the same time the server name is changed from <localhost> to <www.mybbb.edu>.
nginx and bbb-server were then restarted. the commands bbb-conf --clean and bbb-conf --check were also done.
there is also link betwenn sites-available/bigbluebutton and sites-enabled/bigbluebutton.
the bbb-server is setup only for personal educational purpose. the linux-ubuntu machine and win 7 machine are on the same LAN.
from win 7 machine i can contact to the machine where bbb-server is installed only with the ip-address 192.168.0.13. with ip i have access to <welcome to nginx> site.
when i try to connect from win 7 machine to bbb-server with the my not official internal url - server name "www.mybbb.edu" i get the message <the server is not found>.
on the other hand, it is possible to have the first bbb - Demo-site with the above server name <www.mybbb.edu> (interactively on the same machine (ubuntu)) using the browser.
but when i use the ip- 192.168.0.13 i get <welcome to nginx>.

Nginx is configured by bbb-conf to respond to only one hostname or ip address at a time. When you ran --setip <hostname> the ip no longer works. You could run --setip <ip_address> and now the hostname won't work, but the ip will.

Unless you have some sort of DNS entry your Windows 7 machine has no idea how to resolve www.mybbb.edu. You have to either manually add a DNS entry on the Windows machine to resolve www.mybbb.edu as 192.168.0.13, or use --setip to reset the server to respond to the ip only.

You can also mostly ignore the "IP does not match" warnings. They are there to tell you that you're server won't be useable unless you've setup your custom network configuration correctly.

I forgot to add this, but you could also purchase a domain name and set up the DNS entry to resolve to an internal ip address (192.168.0.13). I think that would work as well.

Thank you very much indeed Chad.
I've already a domain name but didn't use it till now. I'will try it. I will look around how to assign a DNS entry for my private IP.

Thank you it has worked with DNS entry on the windows machine.
