NAME
       uucico - UUCP file transfer daemon



SYNOPSIS
       uucico [ options ]

DESCRIPTION
       The  uucico daemon processes file transfer requests queued
       by uucp (1) and uux (1).  It is started when uucp  or  uux
       is  run (unless they are given the -r option).  It is also
       typically  started  periodically  using  entries  in   the
       crontab table(s).

       When  invoked with -r1, --master, -s, --system, or -S, the
       daemon will place a call to a remote  system,  running  in
       master  mode.   Otherwise  the  daemon will start in slave
       mode, accepting a call from a remote system.  Typically  a
       special login name will be set up for UUCP which automati-
       cally invokes uucico when a call is made.

       When uucico terminates, it invokes the uuxqt  (8)  daemon,
       unless the -q or --nouuxqt option is given; uuxqt (8) exe-
       cutes any work orders created by uux (1) on a remote  sys-
       tem,  and  any  work  orders  created  locally  which have
       received remote files for which they were waiting.

       If a call fails, uucico will normally refuse to retry  the
       call  until  a  certain  (configurable) amount of time has
       passed.  This may be overriden by the -f, --force,  or  -S
       option.

       The  -l,  --prompt,  -e,  or --loop options may be used to
       force uucico to produce its own prompts of "login:  "  and
       "Password:".   When  another  daemon calls in, it will see
       these prompts and log in as usual.   The  login  name  and
       password  will normally be checked against a separate list
       kept specially for  uucico  rather  than  the  /etc/passwd
       file;  it  is possible on some systems to direct uucico to
       use the /etc/passwd file.  The -l or --prompt option  will
       prompt  once and then exit; in this mode the UUCP adminis-
       trator or the superuser may use the -u or  --login  option
       to  force  a  login  name,  in  which case uucico will not
       prompt for one.  The -e or --loop option will prompt again
       after  the first session is over; in this mode uucico will
       permanently control a port.

       If uucico receives a SIGQUIT, SIGTERM or  SIGPIPE  signal,
       it  will  cleanly  abort  any  current conversation with a
       remote system and exit.  If it receives a SIGHUP signal it
       will  abort any current conversation, but will continue to
       place calls to (if  invoked  with  -r1  or  --master)  and
       accept  calls  from  (if  invoked with -e or --loop) other
       systems.  If it receives a SIGINT signal  it  will  finish
       the current conversation, but will not place or accept any

       more calls.

OPTIONS
       The following options may be given to uucico.

       -r1, --master
            Start in master mode (call out to a system);  implied
            by  -s,  --system, or -S.  If no system is specified,
            call any system for which work is waiting to be done.

       -r0, --slave
            Start in slave mode.  This is the default.

       -s system, --system system
            Call the named system.

       -S system
            Call  the  named  system, ignoring any required wait.
            This is equivalent to -s system -f.

       -f, --force
            Ignore any  required  wait  for  any  systems  to  be
            called.

       -l, --prompt
            Prompt  for  login  name and password using "login: "
            and "Password:".  This allows uucico to be easily run
            from  inetd  (8).   The  login  name and password are
            checked against the UUCP password file, which  proba-
            bly  has  no connection to the file /etc/passwd.  The
            --login option may be used to force a login name,  in
            which cause uucico will only prompt for a password.

       -p port, --port port
            Specify a port to call out on or to listen to.

       -e, --loop
            Enter  endless  loop  of  login/password  prompts and
            slave mode daemon execution.  The  program  will  not
            stop  by  itself;  you  must  use kill (1) to shut it
            down.

       -w, --wait
            After calling out (to a particular  system  when  -s,
            --system,  or -S is specifed, or to all systems which
            have work when just -r1  or  --master  is  specifed),
            begin an endless loop as with --loop.

       -q, --nouuxqt
            Do not start the uuxqt (8) daemon when finished.

       -c, --quiet
            If  no  calls  are permitted at this time, then don't
            make the call, but also do not put an  error  message

            in  the  log file and do not update the system status
            (as reported by uustat (1)).  This can be  convenient
            for automated polling scripts, which may want to sim-
            ply attempt to call every system  rather  than  worry
            about  which  particular systems may be called at the
            moment.  This option also suppresses the log  message
            indicating that there is no work to be done.

       -C, --ifwork
            Only  call  the system named by -s, --system or -S if
            there is work for that system.

       -D, --nodetach
            Do not detach from the  controlling  terminal.   Nor-
            mally  uucico  detaches from the terminal before each
            call out to another system and before invoking uuxqt.
            This option prevents this.

       -u name, --login name
            Set  the  login  name  to  use instead of that of the
            invoking user.  This option may only be used  by  the
            UUCP  administrator  or  the superuser.  If used with
            --prompt, this will cause uucico to prompt  only  for
            the password, not the login name.

       -z, --try-next
            If  a  call fails after the remote system is reached,
            try the next alternate rather than simply exiting.

       -i type, --stdin type
            Set the type of  port  to  use  when  using  standard
            input.   The  only support port type is TLI, and this
            is only available on machines which support  the  TLI
            networking interface.  Specifying -iTLI causes uucico
            to use TLI calls to perform I/O.

       -x type, -X type, --debug type
            Turn on particular debugging  types.   The  following
            types  are  recognized:  abnormal,  chat,  handshake,
            uucp-proto, proto, port, config,  spooldir,  execute,
            incoming, outgoing.

            Multiple types may be given, separated by commas, and
            the --debug option may appear multiple times.  A num-
            ber  may  also be given, which will turn on that many
            types from the foregoing list; for example, --debug 2
            is equivalent to --debug abnormal,chat.

            The  debugging  output is sent to the debugging file,
            usually      one      of       /var/spool/uucp/Debug,
            /var/spool/uucp/DEBUG,                             or
            /var/spool/uucp/.Admin/audit.local.

       -I file, --config file
            Set configuration file to use.  This option  may  not
            be available, depending upon how uucico was compiled.

       -v, --version
            Report version information and exit.

       --help
            Print a help message and exit.

FILES
       The file names may be changed at compilation  time  or  by
       the  configuration file, so these are only approximations.

       /etc/uucp/config - Configuration file.
       /etc/uucp/passwd - Default UUCP password file.
       /var/spool/uucp - UUCP spool directory.
       /var/spool/uucp/Log - UUCP log file.
       /var/spool/uucppublic - Default UUCP public directory.
       /var/spool/uucp/Debug - Debugging file.
