uucpd(ADMN)                     19 June 1992                     uucpd(ADMN)


 Name

    uucpd - UUCP server


 Syntax

    uucpd


 Description

    uucpd is the server for supporting UUCP connections over networks.


    uucpd is invoked by inetd(ADMN) when a UUCP connection is established
    (that is, a connection to the port indicated in the uucp service specifi-
    cation; see services(SFF)), and executes the following protocol:

    1.  The server prompts with login:.  The uucico(ADM) process at the other
        end must supply a username.

    2.  Unless the username refers to an account without a password, the
        server then prompts with Password:.  The uucico process at the other
        end must supply the password for that account.


    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 LOG-
    NAME set to the specified username.  An entry is made in /etc/wtmp for
    the username.
