NAME

     telnetlogin — login wrapper for telnetd

SYNOPSIS

     telnetlogin [-h host] [-p] [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.

SEE ALSO

     login(1), inetd.conf(5), inetd(8), telnetd(8)

RESTRICTIONS

     telnetlogin does not permit the -f option to login, so will not work with telnetds that
     perform authentication via Kerberos or SSL.

     THIS IS PRESENTLY EXPERIMENTAL CODE; USE WITH CAUTION.

HISTORY

     telnetlogin was written during the development of NetKit 0.17.
