I am inheriting about 20 linux servers running different versions of Ubunutu (7 and above). The current setup has people logging in(ssh) with a shared login (it was explained to me that this was done to ease user management) or as root. I assume it would be safer/more customizable to log in to each box using one's own login, right? And sshing in as root is a Bad Thing yes? There's only two of us, but I may want to institute different permissions per user.
What would you suggest, while keeping complexity to a minimum?
