When I try, in flamerobin, create a new database, I get the following message:
*** IBPP::SQLException ***
Context: Database::Create
Message: isc_dsql_execute_immediate failed

SQL Message : -902
Unsuccessful execution caused by a system error that precludes
successful execution of subsequent statements

Engine Code : 335544344
Engine Message :
I/O error for file "/home/miguel/ff.fdb"
Error while trying to create file
Permission denied

How can I resolve it?

Thanks,
Miguel
