Hi Mark,

AOL uses a transparent proxy for connecting their users to the internet.
This proxy does not forward open socket connection to ports others than e.g 80 or 443.

I you have the possibility to run the server on port 80 or 443 whith its own IP, this would solve the problem.

Hi Stefan,

thanks for your answer.

But wonÂ´t there be a conflict between apache and the chat port?

Not, if you assign the chatserver to a second IP:
E.g
- Using 192.168.1.3:80 for Apache
- and 192.168.1.4:80 for the chatserver on the same host.

A second network card is not really necessary, because you can listen to multiple IPs using virtual network interfaces.

Code:

ifconfig eth0:1 up 192.168.1.4 255.255.255.0

But your router must be able to make DNAT per IP (maybe that will be the problem). And you definately need a second official IP.

Hi Stefan,

now I got the following error message:

Code:

ServerMain java.net.BindException: Address already in use

What now?

I have split the apache via the virtual hosts. One for the native and one for the virtual IP.

No way.

Any suggestions?

Thanks a lot,

Mark

Hi Mark,

if apache is listening on 192.168.1.1:80 you can bind the chat server to 192.168.1.2:6678.
For doing that choose the following configuration in the server.ini:

Code:

LogLevel = 6
LogFile = /var/log/ilias_chatserver.log
IpAddress= 192.168.1.2
Port = 6678
HeaderFileName = {PATH_TO}/header.html
FooterFileName = {PATH_TO}/footer.html
Authentication = 1
ConnectionsFrom = 192.168.1.1

Restart the chatserver. If you still receive messages like 'Address already in use' use 'ps -ax' to check if a chat server is already running. If yes, kill that process.

Hi Stefan,

this is not the problem. But at least I solved it:

You told me to bind the chat on a second IP Adress on port 80 or 443 so that AOL Users wolud be able to chat, too.

So I took a second IP Adress as a virtual alias (SuSE 9.2). But now Apache listens to both IP Adresses. The reason has been, that I have to comment the line in the httpd.conf where ssl listens to the port 80.

Code:

<IfDefine SSL>
# Listen 80
Listen 443
</IfDefine>

After this I could bind Apache to the origin IP Adress via Listen.

Now the chat listens to the virtual IP on port 80 and I hope that even AOL Users would be able to chat.

Thanks,

Mark

Hallo,

sorry, jetzt in deutsch, das wird mir fÃ¼r mein miserables Englisch zu heikel:

Mittlerweile habe ich Feedback von zwei AOL Nutzern bekommen. Es hat nicht funktioniert! Ich habe alles so gemacht, wie oben beschrieben. Der Chat lauscht auf einer anderen IP-Adresse auf Port 80. Aber es klappt nicht

Vielleicht noch eine Idee?!?!!?

Vielen Dank,

Mark
