Doesn't help. The server runs as user "firebird" independently of you.

You used the "localhost:..." connection string. This means that the
client (isql) will try to establish TCP/IP connection to server at port
3050. The server itself runs as user "firebird" so file:


has to be readable by user "firebird". From "ls -l" output you sent,
that is clearly not the case:

-rw-r--r-- 1 root root

If you wish to have advantage of being "root", connect directly to the
database file:

./isql /usr/lib/firebird2/examples/employee.fdb

That should work, but it doesn't solve the initial problem.

Perhaps you have firewall active, or inetd is dropping the connection.
Take a look at /etc/hosts.allow and /etc/hosts.deny files if they exist
on your system. Also try:

iptables -t nat --list

to see if you have some firewall rules set up.
