I have a network of 5 Windows Machines and 1 Linux Server. I created a Filemaker Pro Database on a windows machine and share it with the other machines through web publishing (only locally). - On any Internet browser, they only have to go the IP of the computer hosting the database - http://192.168.1.99:120 to enter & use the database, and all the other windows machines connect perfectly.
However, when I type the same IP(+port No.) into Firefox on my Linux computer, it can't reach the windows computer with the database (It just times out). Is there a firewall preventing it from connecting to other computers on the network, or do I need to update firefox or run another Internet browser or install Samba? I don't have much experience with Linux, as a programmer set the server up for me, so a simple solution with as little programming as possible would be fantastic.
Thanks for your reply. I tried pinging the linux server , from my windows machine but it was timed out. No Connection. I opened a terminal windows on the linux computer and tried the commands

3. telnet 192.168.1.99 100 (the port number is 100)
Trying 192.168.1.99...
telnet: connect to address 192.168.1.99: Connection timed out
telnet: Unable to connect to remote host: Connection timed out
I tested the address http//192.168.1.99:100 from the other windows machines and they all work fine, and connect to the database.Mmmmmm
