Yep, Cisco bought psionic; since then, psionic.com has disappeared,
and the freshmeat.net entry for portsentry has been deleted.

Worse, portsentry was not open source; while it was distributed as
source, its license specifically forbids modification.  So Cisco now
owns it, lock stock and barrel. (I suppose they probably wouldn't have
paid $12M for it otherwise.)

One alternative is psad, from www.cipherdyne.com.  It's explicitly
written as a replacement for portsentry from both a legal and
technical view (it integrates with the Linux firewalling code rather
than sitting inside the firewall).  I haven't tried it yet, but I plan
to when I upgrade my mailserver.
