NAME

     telnetlogin -- login wrapper for telnetd

SYNOPSIS

     telnetlogin [-h host] [-p] [-f username] [username]

DESCRIPTION

     telnetlogin is a setuid wrapper that runs login(1).  It is meant to be invoked by telnetd(8); the idea is to remove the necessity of running
     telnetd as root.

     telnetlogin should be installed mode 4750, user root, group telnetd. Then, telnetd may be run from /etc/inetd.conf as user ``nobody'', group
     ``telnetd'', and with the option -L path-to-telnetlogin.

     telnetlogin accepts only the subset of options to login(1) shown above, in the order listed. This is the order telnetd 8 normally provides
     them in.  telnetlogin also does sanity checks on the environment variables TERM, and REMOTEHOST.  It also insists that the standard input,
     output, and error streams are open on a terminal, and that it is the process group leader of the foreground process of that terminal. After
     checking all of these conditions, checking the values of the above environment variables for reasonable values, resetting signal handlers,
     and so forth, it execs login.
