[SUMMARY] Update password on lots of systems - without NIS

Apparently this is not as uncommon as I thought. I've received quite
a number of responses, so here's the summary:

- Expect and rdist were the two big responses here. Looking at the
web sites and notes for each, I've had to opt for expect to fit our
setup, with their 'passmass' script a perfect fit. rdist would be
useable here only if I could permit it to be copied everywhere, and
that I knew was next to impossible; One server was, so expect it is.

- Perl was another favorite, but the same problem applies as per
rdist here (plus I'd have to learn Perl, which I still want to do,
just too durn many things going on, argh). A couple of people also
suggested a csh/sed/awk combo, which I've considered but was a bit
unwary for me (again, not enough time -- I've got too many other
major script projects).

- Some folks are curious why I'm not using NIS/NIS+ -- Well, I'd like
to use it too, make this tons easier :). The best explaination is
that the remote sites must have total network independence from our
LAN in case of a link cut -- There have been too many problems when
someone with a misplaced backoe just causes havoc (like that one
Big Game lottery state that lost connectivity yesterday...).

I can't thank everyone enough for responses; I'd mention them, but
it's durn near impossible to cut/paste addresses from Outlook
Express (No deadly looks please, I'm doin' this from home).

Now I need to get Expect installed and running; Wish me luck...
