Subject Can't connect to CentOS 7 service port 3050 from network

Hi to all

I've just installed Firebird 2.5 SuperClassic on a new Linux CentOS 7 box. I tested local connections and are working fine. SELinux is disabled and firewall service is down.

But when I try to connect from a workstation using "telnet my-server 3050", is not responding. Neither I can see the 3050 port if I do "lsof | grep 3050" on the host.

Is there I've missed?

Do I need a 64 bit client for connecting to FB on a CentOS 7?

Any help will be appreciated.

Best regards,
