Does anyone know how to limit a user's ability to navigate the file system. I know that FTP automatically creates a false root so that an anonymous FTP connection cannot get below that directory. I would like to be able to allow certain users a login and rights to their home directory ONLY!! I have set very restrictive rights, only to get numerous errors upon login. Even with these restrictive permissions the user can look around if they know UN*X filesystems.

Any help would be appreciated.

How fortuitous that I have only recently completed reading O'Reilly's lovely book "Learning the Bash Shell". Bash, and perhaps tcsh also, has a restricted mode that it can be run in. If it is run as 'rbash' or with the parameter -r it will prevent a user from many actions, including modifying certain variables such as the PATH, changing the current directory, using the shell's 'exec' command and other such things. Thus you can supply users with a set of programs you consider safe as well as space to store documents and configuration files. Try 'man bash' and search for RESTRICTED SHELL. Please note that this should not be considered completely secure. However, it will probably stop all but the most wily troublemakers. -josh -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
