i use the following deffinition for the trigger in the database:

/***************************************************************************
***/

SET SQL DIALECT 3;

SET NAMES NONE;


SET TERM ^ ;


CREATE TRIGGER DATA_AI0 FOR DATA
ACTIVE AFTER INSERT POSITION 0
AS
begin

POST_EVENT 'NEWDATAREADY';
end

SET TERM ; ^

/***************************************************************************
***/

then i use the following c-code:

// -------------------------------------------------------------------------
-----

try
{
IBDatabase1->Connected = true;
IBEvents1->UnRegisterEvents();
IBEvents1->Events->Clear();
IBEvents1->Events->Add("NEWDATAREADY");
IBEvents1->RegisterEvents();
}
catch (Exception &exception)
{
Application->ShowException(&exception);
Application->Terminate();
}

// -------------------------------------------------------------------------
-----

i use the following objects from C++:
TIBDatabase
TIBTransaction
TIBDatabase
TIBEvents

then i get the following error code:

Unable to complete network request to host "jandrim"
Failed to establish a secondary connection for event processing.


if i remark IBEvents1->RegisterEvents(); then i could access
the database normal (read/write).

the same happens when i use Delphi.

hardware/software:
server:
linux (kernel 2.4.18)
Firebird 1.0 stable
one nic (ip-addr: 192.168.100.12)

client:
windows 2000 SP2
one nic (ip-addr: 192.168.100.70)
gds32.dll (6.5.0.28)

there is no (!!!) firewall

thanks for support
