I meant installing XAMPP to run the Apache and MySQL services. I have only installed this on my PC in the network, for testing. So all installations: XAMPP, MySQL, OpenFire, and Spark are now on my computer using localhost as the server name.
The error when I tried to connect from another PC, and I can ping by IP and name to my PC from that one, I get the error = Can’t connect to server, invalid name or server not reachable.
The PC where OpenFire is installed and connected is on the DNS, so is the other PC (they can ping each other by name and IP).
Now, when I open my Spark client, I use the server localhost. What should I do on the other PC so that I can reach my localhost server?
If you put the system’s LAN ip in the ‘server’ field, does it work? You said you can ping it by name from another system - Have you tried using that name?
Have you verified the firewall is turned off or allows tcp/5222?
