I'm not sure, if the question belongs here. How can I find out if an application tries to connect to Firebird? I could imagine using Wireshark, but is there an easier way?
Long story: I wrote an application which used to work, and now it fails with the message "unavailable database". This is no programming question, since I know the exact place where it happens and I'm perfectly sure, it's alright. Older binaries stopped working, too. Fresh Firebird installation didn't help, and Firebird itself works, too. I can connect to it using telnet, ISQL works. I tried to switch off the firewall.
I see, I forgot some important details:
- it's XP64
- it's Firebird 2.5, but I had the same problem with 2.1
- both client and server run on localhost
- the client aborts immediately with the error "unavailable database"
- I can connect to FB using isql or other tools
I know, this looks like a problem of a newbie who can hardly switch his computer on. It's weird.
