i got a free shells server on freebsd, i offer free access to my server to enyone, the amount of request for new shells has been to heavy for me and i can keep up with adding new users automaticly, i write a shell (sh) script that takes care of everything for me, i create a new user 'newuser' ...i promote 'newuser' to 'wheel' ...then i try to assign 'free.sh' as default shell for 'newuser' so when some body logs as 'newuser' runs my script, then my script will create the new user on my system ...but unfurtunatly freeBSD do not letme assign my script as shell, what am doing wrong? ...if there is any way i can let some body or some how automaticly add users to my system....its any already made script, program? or ??? please help.
