NAME
     in.uucpd, uucpd - UCP server

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


DESCRIPTION
     in.uucpd is the server for supporting UCP connections  over
     networks.


     in.uucpd is invoked by inetd(1M) when a UCP  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) pro-
              cess 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 password is correct.

SECURITY
     in.uucpd uses pam(3PAM) for authentication, account  manage-
     ment, 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  authentication,  account
     management, and session management module.

       uucp    auth requisite          pamauthtokget.so.1
       uucp    auth required           pamdhkeys.so.1
       uucp    auth required           pamunixauth.so.1

       uucp    account requisite       pamroles.so.1
       uucp    account required        pamprojects.so.1
       uucp    account required        pamunixaccount.so.1

       uucp      session required      pamunixsession.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.

     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). Responsibility  for  initiating  and  restarting
     this  service  is delegated to inetd(1M). Use inetadm(1M) to
     make configuration changes and to view configuration  infor-
     mation for this service. The service's status can be queried
     using the svcs(1) command.


     The pamunix(5) module is no longer supported. Similar func-
     tionality     is     provided    by    pamauthtokcheck(5),
     pamauthtokget(5),   pamauthtokstore(5),   pamdhkeys(5),
     pampasswdauth(5),  pamunixaccount(5),  pamunixauth(5),
     and pamunixsession(5).
