User Monitoring

[David Schulz]

Hello all,

i would like to provide a SSH Login for selected people on a  
dedicated Machine, to be a little bit of a playground to some who  
dont have any Unix experience and so on.

Without a doubt i will get the one or the other trying to do  
something nasty to the Box, so my question is how to keep track of  
what Users are doing? Using process accounting as described http:// 
www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/security- 
accounting.html in the handbook?

Can you share some easy to implement tricks to keep the worst from  
happening to my Machine?

Thanks,
David
