Installing Firebird 5

[Luis Feliz]

Hi, I have used Firebird for quite a long time.  I  had to migate an app and went from Firebird 2. to latest 5.0x.  on AWS.    I was on Windows 2016 server, but goal was to deploy on Linux.  My first attempt to instal on Ubuntu 20.10 LTS,   installed fine,   uploaded and restored back up file.   I opened port 3050 , verified firewall accepted change and restarted server.

Not able to access the machine with Firebird client app.  I can still SSH into it.  I tried again and no luck.   I finally just went to a Windows Server2016 instance, installed  Firebird 5,  opened  port 3050  in Widows  firewall , restore backup and was able to remotely access the database.

Is there a good step by step guide to install Firebird 5.0 on ubuntu or debian for use as a db server on a network.   I will keep deploying on Windows for now and will give  Ubunutu another shot 

- Lou

Have you verified that it's actually listening on an accessible IP address?

Also, exactly what error do you get? And have you upgraded you Firebird
client library to a newer version? Security configuration has changed
considerably since Firebird 2, and with the default configuration, a
Firebird 2 client will not be able to connect (IIRC, resulting in error
"connection rejected by remote interface").

You didn't say "installed Firebird 5" on Ubuntu, so the natural question: did
you?

 I have not installed FB on Linux since I created my 2.5 servers several years ago!

YEs.  Copied the newer client library out to app ,  verified firebird,conf was not set to listen to localhost but *.*.*.*   made sure firebird user conrolled the database and backup folder.  Copied my backup and restore scrpt to ubuntu along with backup file.   Restored the db taking 2.5 back to 5, no problem.  made sure port 3050 was open in uFW  rebooted, UFW was active and getting the "connection rejected by remote interface"   After trying on Ubuntu and Aws Linux, I just went to Windows  FB5 server  (taking the above ites into account) and works fine.   I will try the link to video that was shared and see if I missed something. 

I will report back here if and when I get it running on linux.

The message "connection rejected by remote interface" means that you
*were* able to connect to the server, but the server and client couldn't
agree on the connection; and that very likely means you're still using a
Firebird 2.5 or older client library, with the default value (Required)
for the setting WireCrypt in firebird.conf of the server.

If you hadn't been able to connect to the server because it wasn't
exposed, or blocked by a firewall, you would have received the error
"Unable to complete network request to host "<hostname>".
