in.uucpd is the server for supporting UUCP connections over networks.
in.uucpd is invoked by inetd.1m when a UUCP connection is established (that is, a connection to the port indicated in the ``uucp'' service specification; see services.4 and executes the following protocol:
If the username is not valid, or is valid but refers to an account that does not have /usr/lib/uucp/uucico as its login shell, or if the password is not the correct password for that account, the connection is dropped. Otherwise, uucico is run, with the user ID, group ID, group set, and home directory for that account, with the environment variables USER and LOGNAME set to the specified username, and with a -u flag specifying the username. Unless the -n flag is specified, entries are made in /var/adm/utmp, /var/adm/wtmp, and /var/adm/lastlog for the username. in.uucpd must be invoked by a user with appropriate privilege (usually root) in order to be able to verify that the password is correct.
All diagnostic messages are returned on the connection, after which the connection is closed.
