[comp.unix.xenix] Prohibiting Shell escapes from within NN

eastick@me.utoronto.ca (Doug Eastick) (02/17/90)

Has anyone hacked NN to disallow shell escapes?  If NN was to be used
in a BBS environment, it would be nice if you could stop people from
getting to the shell, vi, etc...

"#ifdef RESTRICT_SHELL" in the appropriate places would be nice.

Trying to avoid some work...
