GSEC — Firebird User Administration

GSEC is Firebird’s command line tool for user administration issues.

All database users are stored in the security database named isc4.gdb (Firebird 1.0), security.fdb (Firebird 1.5) or security2.fdb (Firebird 2.0) in the Firebird directory. There is always at least one user, the system database administrator, SYSDBA.

After installation, the SYSDBA password is “masterkey”. (Exception: Firebird 1.5 for Linux)

Only the first 8 characters of a password are significant. The password should not contain space characters.

Invoking GSEC

GSEC can only be run by the SYSDBA.

To use GSEC for the local machine, use:

gsec -user sysdba -password <password> [options]

To use GSEC for a remote machine, use:

gsec -user sysdba -password <password> -database <databasename>

where is the database name of the remote security.fdb or security2.fdb database.

You can use GSEC has an interactive command line tool or give all commands on one command line.
