Subject RE: [firebird-support] Tcp-wrapper support
Author Rick Debay
I would like to manage all network connections through a standard
generic interface, instead of having to use Firebird's (or whatever
other application needs managing). Libwrap (the tcp-wrapper library) is
robust and easy to manage. I don't want Firebird to have to worry about
what connections to accept or drop, that's the responsibility of the
operating system's networking stack.
For example, I can allow connections from, and libwrab
will perform multiple DNS lookups to prevent spoofing. AFAIK Firebird
doesn't have that capability.

Yes, yes, yes, and yes. In our non-homogeneous environment, I can't
restrict users to secure connections only (SSL, etc) but I can throw a
big speed-bump in front of port 3050 by locking it down by configuring

Even Superserver, which manages its own attachment requests?

Reading about tcp wrapper (assuming that's what Rick means by
"tcp-wrapper"), it seems to do pretty much a combination of what you can
configure the Firebird server to do for itself and what you can
configure the tcp service to allow or deny.

It was a rather vague question: what do you want Firebird to do that
it's not doing already? Log requests? Control all accesses to the
server and auxiliary ports? Override keepalive? Something else?
