NAME

       in.uucpd, uucpd - UUCP server

SYNOPSIS

       /usr/sbin/in.uucpd [-n]

DESCRIPTION

       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, and executes the following protocol. See services(4):

       1.  The server prompts with login:. The uucico(1M) 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  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/utmpx, /var/adm/wtmpx, 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 pass-
       word is correct.

SECURITY

       in.uucpd uses pam(3PAM) for authentication, account management, and session management.	 The  PAM  configuration  policy,  listed  through
       /etc/pam.conf,  specifies the modules to be used for in.uucpd. Here is a partial pam.conf file with entries for uucp using the UNIX authen-
       tication, account management, and session management module.

       uucp    auth requisite	       pam_authtok_get.so.1
       uucp    auth required	       pam_dhkeys.so.1
       uucp    auth required	       pam_unix_auth.so.1

       uucp    account requisite       pam_roles.so.1
       uucp    account required        pam_projects.so.1
       uucp    account required        pam_unix_account.so.1

       uucp	 session required      pam_unix_session.so.1

       If there are no entries for the uucp service, then the entries for the "other" service will be used. If multiple authentication modules are
       listed, then the peer may be prompted for multiple passwords.

FILES

       /var/adm/utmpx	       accounting

       /var/adm/wtmpx	       accounting

       /var/adm/lastlog        time of last login

DIAGNOSTICS

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

       user read	       An error occurred while reading the username.

       passwd read	       An error occurred while reading the password.

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

NOTES

       The in.uucpd service is managed by the service management facility, smf(5), under the service identifier:

       svc:/network/uucp

       Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). Responsibil-
       ity for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view config-
       uration information for this service. The service's status can be queried using the svcs(1) command.

       The pam_unix(5) module is no longer supported. Similar functionality is provided  by  pam_authtok_check(5),  pam_authtok_get(5),  pam_auth-
       tok_store(5), pam_dhkeys(5), pam_passwd_auth(5), pam_unix_account(5), pam_unix_auth(5), and pam_unix_session(5).
