Subject Re: [firebird-support] Losing Firebird connection into a VPS
Author Chuck Belanger

Thank you for your reply:

Please provide more information:

- Which Firebird version (full version)? Firebird 3.03.32900
- What OS (and its version)? Windows 10 Pro, 1803 client, Remote Server on VPS is Windows server 2008
- What kind of firewall and virusscan software is used: No virus scan at the remote VPS, that I am aware of; Windows Firewall.

We have asked, and the hosting company denies it, but I am not totally sure that the hosting server does not terminate long running TCP/IP sessions.

Are there better questions to ask the hosting company?
Thank you again,

My background with Firebird has been mostly to use it for a local
desktop application. A few years ago we started to experiment with a
remote connection on a website and I have had no issues with that other
than the speed.

Recently, we plan to use FB 3 and a database as a remote application
authorization process. We shifted to a VPS hosting and what I have been
seeing is that while using IBExpert to connect, after maybe a couple of
minutes it is disconnected from the database. I have not tried to
connect through the application yet, but use IBExpert to do maintenance
on the remote database.

I have reviewed the Firebird conf file and cannot find any settings
which would cause this, nor can I find any settings (the connection
timeout is set for 0, which I assume means indefinite connection) in
IBExpert, nor are there any settings in the server windows firewall. We
also asked the hosting company about this and they did not seem to 

Does anyone have any ideas on what I need to do to keep connected to 
remote (VPS) Firebird server?

Are you sure the hosting party doesn't terminate long running TCP/IP 
connections? I once had a problem with using web sockets, and it turned 
out that incoming TCP/IP connections that were open for a few minutes 
got killed automatically, as the expectation was for REST-like services 
with short request/response cycles.
