  NAME

    uucpd - Supports UUCP connections over networks

  SYNOPSIS

    /usr/lib/uucp/uucpd

  DESCRIPTION

    The uucpd daemon is the server for supporting UUCP connections over
    networks.

    The uucpd daemon is invoked by inetd 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:

    1.  The server displays the login: prompt.  The uucico process at the
        other end must supply a username.

    2.  The server then displays the Password: prompt unless the username
        refers to an account without a password.  The uucico process at the
        other end must supply the password for that account.

    The connection is dropped if any one of the following is true:

    ⊕  The username is not valid.

    ⊕  The username is valid but refers to an account that does not have
       /usr/lib/uucp/uucico as its login shell.

    ⊕  The password is not the correct password for the account.

    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.  Entries are made in /etc/wtmp for the username.

  FILES

    /etc/wtmp   Accounting file.

  DIAGNOSTICS

    All diagnostic messages are returned on the connection, after which the
    connection is closed.
