NAME
      in.uucpd, uucpd - UUCP server
 


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


DESCRIPTION
      in.uucpd is the server for supporting UUCP connections  over
      network.
 
      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  follow-
      ing 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  pass-
         word,  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         required      /usr/lib/security/pam_unix.so.1
      uucp         account      required      /usr/lib/security/pam_unix.so.1
      uucp         session      required      /usr/lib/security/pam_unix.so.1
 
 
      If there are no entries  for  the  uucp  service,  then  the
      entries  for  the  "other" service will be used. If multiple

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.
