I have installed FB 1.5.2 on RH Fedora 4. With isql, I can connect to
employee.fdb, and do any DML I want, with this:
CONNECT /opt/firebird/examples/employee.fdb -user sysdba -password abcd1234

But if I try the following (again, with isql on the same machine as the
Firebird installation) , I get "INET/inet_error: connect errno 111"
CONNECT 192.168.0.107/opt/firebird/examples/employee.fdb -user sysdba
-password abcd1234

That _is_ the correct IP address.

If I try to connect from another machine on the network (e.g. with
IB_SQL), I get this:

ISC ERROR CODE:335544721
ISC ERROR MESSAGE:
Unable to complete network request to host "192.168.102.207".
Failed to establish a connection.
No connection could be made because the target machine actively refused it..

Clearly, the server is running, since I can read data with isql. I have
re-installed Firebird several times, to try to get the server to listen
on port 3050, but a netstat listing does not show/include port 3050. (So
how does isql manage to connect?)

What would cause this situation, where isql on the server can connect,
as long as the path does not include the IP address?
