Firebird: Unable to complete network request to ho

Question

I'm trying to connect to a remote Firebird database "test" (alias already added). It is not an embedded server, and is installed on VM with IP 192.168.1.147.

Here is my connection string:

User=sysdba;Password=masterkey;Database=test;DataSource=192.168.1.147

However I got an error:

FirebirdSql.Data.FirebirdClient.FbException (0x80004005): Unable to complete network request to host "192.168.1.147". ---> Unable to complete network request to host "192.168.1.147".

I've done some research on that but haven't got a clue yet. Some help needed. Thanks

My IP address is 192.168.2.108, and I can ping that server IP successfully

Answer 1

For Linux, the Firebird port is closed by default. You need to modify RemoteBindAddress in /etc/firebird/2.5/firebird.conf from

RemoteBindAddress = localhost

to

RemoteBindAddress =

and restart service.

Answer 2

Make sure you have excluded tcp port 3050 in VMs' firewall.

Answer 3

Make sure that

1. Firebird is running
2. Firebird is listening on port 3050 on the specified IP (or on 0.0.0.0)
3. Your firewall allows access to port 3050
