Re: Linux and passwordless ssh
Can be done, create a userid, edit /etc/shadow where the actual passwords are stored in encrpted form and set the second : separated field to nothing (::) and then run something like mkpw_db (can't recall the name offhand to re-create the password database). /etc/ssh/sshd_config should be adjusted to cater for passwords and allow empty passwords and thereafter ssh access will drop straight in.

Not wise to do so. What I've done in the past is create my own alternative shell. Edit /etc/shells to include my own script, in /etc/passwd set that script as the shell for a user (last field of the users passwd entry). In the script set up a while :;do read ANS;done loop and all that user will be able to do is enter text. Evaluate ANS within that loop and you can add actions ... if [ "$ANS" = "dir" ];then ls;fi ... whatever.

.... A Meteor is an example of a rock star.
