   5 NAME
   6        in.uucpd, uucpd - UUCP server

   8 SYNOPSIS
   9        /usr/sbin/in.uucpd [-n]
  10 
  11 
  12 DESCRIPTION
  13        in.uucpd is the server for supporting UUCP connections over networks.
  14 
  15 
  16        in.uucpd is invoked by inetd(1M) when a UUCP connection is established,
  17        that is, a connection to the port indicated in the "uucp" service
  18        specification, and executes the following protocol. See services(4):
  19 
  20            1.     The server prompts with login:. The uucico(1M) process at
  21                   the other end must supply a username.
  22 
  23            2.     Unless the username refers to an account without a password,
  24                   the server then prompts with Password:. The uucico process
  25                   at the other end must supply the password for that account.
  26 
  27 
  28        If the username is not valid, or is valid but refers to an account that
  29        does not have /usr/lib/uucp/uucico as its login shell, or if the
  30        password is not the correct password for that account, the connection
  31        is dropped.  Otherwise, uucico is run, with the user ID, group ID,
  32        group set, and home directory for that account, with the environment
  33        variables USER and  LOGNAME set to the specified username, and with a
  34        -u flag specifying the username. Unless the -n flag is specified,
  35        entries are made in /var/adm/utmpx and /var/adm/wtmpx for the username.
  36        in.uucpd must be invoked by a user with appropriate privilege (usually
  37        root) in order to be able to verify that the password is correct.
  38 
  39 SECURITY
  40        in.uucpd uses pam(3PAM) for authentication, account management, and
  41        session management.  The PAM configuration policy, listed through
  42        /etc/pam.conf, specifies the modules to be used for in.uucpd. Here is a
  43        partial pam.conf file with entries for uucp using the UNIX
  44        authentication, account management, and session management module.
  45 
  46          uucp    auth requisite          pam_authtok_get.so.1
  47          uucp    auth required           pam_dhkeys.so.1
  48          uucp    auth required           pam_unix_auth.so.1
  49 
  50          uucp    account requisite       pam_roles.so.1
  51          uucp    account required        pam_projects.so.1
  52          uucp    account required        pam_unix_account.so.1
  53 
  54          uucp      session required      pam_unix_session.so.1
  55 
  56 
  57 
  58        If there are no entries for the uucp service, then the entries for the
  59        "other" service will be used. If multiple authentication modules are
  60        listed, then the peer may be prompted for multiple passwords.

  78 DIAGNOSTICS
  79        All diagnostic messages are returned on the connection, after which the
  80        connection is closed.
  81 
  82        user read
  83                            An error occurred while reading the username.
  84 
  85 
  86        passwd read

  89 
  90        Login incorrect.
  91                            The username is invalid or refers to an account
  92                            with a login shell other than /usr/lib/uucp/uucico,
  93                            or the password is not the correct password for the
  94                            account.

  97 NOTES
  98        The in.uucpd service is managed by the service management facility,
  99        smf(5), under the service identifier:
 100 
 101          svc:/network/uucp
 102 
 103 
 104 
 105 
 106        Administrative actions on this service, such as enabling, disabling, or
 107        requesting restart, can be performed using svcadm(1M). Responsibility
 108        for initiating and restarting this service is delegated to inetd(1M).
 109        Use inetadm(1M) to make configuration changes and to view configuration
 110        information for this service. The service's status can be queried using
 111        the svcs(1) command.
 112 
 113 
 114        The pam_unix(5) module is no longer supported. Similar functionality is
 115        provided by pam_authtok_check(5), pam_authtok_get(5),
 116        pam_authtok_store(5), pam_dhkeys(5), pam_passwd_auth(5),
 117        pam_unix_account(5), pam_unix_auth(5), and pam_unix_session(5).
