I run a network of UNIX servers on the Internet, we are primarily a web hosting service. In order to help tighten up security on or networks we are looking into setting up restricted shells for users. This way we can supply each hosting account with their own bin with their own utilities and restricted unix commands available to that account. We are currently running c shell on all user accounts but are going to have to change this as c shell does not support a restricted shell environment. The 2 shells that we are considering are "rsh (Restricted Borne Shell)" and "rksh (Restricted Korn Shell)". My question is this. Does perl, c, c++, g++, and www-perl libraries have any restrictions as to what shells they can run on. If they will not run on any of these shells please tell me which shells have these restrictions. Greg
