Yes, but aside from the 'dir' commands (easily priv changed), show run
is the only command that requires a privileged account. Everything
else you can do at priv 1.

Yep... I think I'm going to get a patch together that logs on twice
for Ciscos - once for an autocmd 'show run' and once with an
unprivileged account to collect all the show info. That way you avoid
the huge security hole introduced by static passwords.
On a side note, what is the difference between the %commands and
@commands list in rancid? Which one does it actually use? I'd like to
prune out all the commands I know my switches/routers don't support
(or in the case of write term, will always support). Do I need to
add/remove any new commands to both lists?

When I'm done I'll let you know ;)

Doesn't get around the fact that you have weak authentication for a
privileged account :)
