Re: Simple way to save login/password info

[Danny Sauer <danny@dannysauer.com>]

Well, you could
  scp /etc/passwd /etc/shadow backupmachine:/backupdir/

That's probably the easiest way. :)  I suppose you could do some
  "awk -F: '$3>1000' > backup"
or
  "for D in /home/*; do grep $D /etc/passwd; done > backup"
kind of thing to get just the non-system accounts.

You should be able to get all the information for accounts on a system
regardless of their database by using the getpw*/getgr* family of
functions (perl, C, whatever language) as root (and restore with
setpw*), too.  But at that point of effort, you'd be better served by
putting everyone in an LDAP backend and just dumping that set of users
to an LDIF periodically.  You could stab your mail server configuration
and stuff in there at the same time, and kill two backup birds with one
lightweight stone, and be better prepared for replication in the future.
:)

--Danny, probably missing some critical piece of information there
