Hi there, i'm trying to use fb 3.0 beta 2 on fresh debian.
I'm usingFirebird-3.0.0.31896-Beta2.amd64.tar.gz, from firebirdsql.org, dated July 03, 2015 ,
which installs on /opt .

First try works from localhost .

Database:  "/opt/firebird/examples/empbuild/employee.fdb", User: 'SYSDBA'
SQL> show version ;
ISQL Version: LI-T3.0.0.31896 Firebird 3.0 Beta 2
Server version:
Firebird/Linux/AMD/Intel/x64 (access method), version "LI-T3.0.0.31896 Firebird 3.0 Beta 2"
on disk structure version 12.0
SQL>

As i cannot connect from other host i run netstat -a,  which gives :

tcp6       0      0 [::]:gds_db             [::]:*                  LISTEN

So, from fresh install there seem to be no ipv4 .

Looking into firebird.conf i see :

#
# Allows setting of IPV6_V6ONLY socket option. If enabled, IPv6 sockets
# allow only IPv6 communication and separate sockets must be used for
# IPv4 and IPv6. Default is false.
#
# Note: on Windows, the socket option can only be set since Windows Vista,
# older versions have it always enabled.
#
# Type: boolean
#
#IPv6V6Only = 0

ps shows 2 processes  :

firebird  3571     1  0 19:19 ?        00:00:00 /opt/firebird/bin/fbguard -pidfile /var/run/firebird/firebird.pid -daemon -forever
firebird  3572  3571  0 19:19 ?        00:00:00 /opt/firebird/bin/firebird

May i look elsewhere to get ipv4 listening ?

Thanks
