27 'uucpd': Unix to Unix Copy relay daemon.
*******************************************

'uucpd' is a relay daemon responsible for accepting TCP transported
connections for 'uucico'.  It is started by 'inetd', conducts any
authentication, and then hands acceptable requests over to 'uucico'.

     uucpd [OPTION]...

27.1 Options
============

There is a single, specific option available:

'-u LOCATION'
'--uucico=LOCATION'
     Replace the hard coded location of 'uucico' with the value
     specified as LOCATION.

27.2 Authentication steps.
==========================

Invocation is expected to be conducted by a protocol described exchange
of user name and password; unfortunately in clear text.  If those agree
with existing local entries, then 'uucpd' verifies that the stated user
also has user shell location identical to the full file system location
of 'uucico'.  Should that not be the case, the request is declined.

   For this latter check, the option '--uucico' is useful when setting
the configuration for 'inetd'.  It is recommended to wrap the invocation
line of 'uucpd' within a call to 'tcpd' in the standard fashion.
