Lost ability to connect remotely to Firebird database after upgrading to Ubuntu Server 13.10

Solution 1:

It's a Debian/Ubuntu change , Firebird should be secure by default (port should be closed by default for the outside world)

Solution 2:

I had a similar problem, this is due to xinet

From a fresh install:

sudo su
apt-get install xinetd
apt-get install python-software-properties
add-apt-repository ppa:mapopa
apt-get update
apt-get install firebird2.5-classic                 
netstat -an | grep 3050             #shows the problem: not binding to 0.0.0.0
nano /etc/firebird/2.5/firebird.conf
    #comment out all RemoteBindAddress = XXXX
nano  /etc/xinetd.d/firebird25
    #set  bind                    = 0.0.0.0
/etc/init.d/xinetd restart
dpkg-reconfigure firebird2.5-classic
netstat -an | grep 3050             #shows the fixed as binding to 0.0.0.0

Solution 3:

1. Remove installed firebird

   sudo apt-get purge firebird*
   

2. Install Xinetd

   sudo apt-get install xinetd
   

3. Download http://sourceforge.net/projects/firebird/files/firebird-linux-amd64/2.5.2-Release/FirebirdCS-2.5.2.26540-0.amd64.tar.gz/download

   Then unzipped folder:

   sudo ./install.sh
   

So it worked for me!
