I want to setup an user SSH/telnet account with useradd. The user should have - read-only permissions for ALL files on the server beginning with the root directory. - write permission for recursively all files below the directory /user/home/newuser How do I setup the account and the permissions correctly ?

This sounds very ugly- and would quite possibly break things such as mail and could very well mess up all sorts of std security.

That sounds like almost the default behaviour. Default install makes lots of things executable by default, but trying to do root-ish things results in failure because the things they try to do are not allowed by permissions set on whatever they're trying to do it to. As a user, I can /sbin/ifconfig, but try changing the routing table. You don't have permissions for that. -- Any technology distinguishable from magic is insufficiently advanced.
