I have used jack_snapshot for this:
(I also think the guys at the soundwire group at ccrma have made
a similar app.)

Another alternative is qjackctl, which has some setting to save
connections to an xml file.

A third option is using emacs lisp. At least I think someone made
emacs bindings to connect jack apps.
