uucico(8)                                                                                          uucico(8)



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 periodi-cally periodically
       cally 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 sys-tem, system,
       tem, 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 automatically 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) executes any work orders created by uux (1) on a remote system, 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 administrator 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 ses-sion session
       sion 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  conversa-tion conversation
       tion with a remote system and exit.  If it receives a SIGHUP signal it will abort any current conver-sation, conversation,
       sation, 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 cur-rent current
       rent 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 probably 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 sys-tems systems
            tems 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 simply 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.  Normally 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, hand-shake, handshake,
            shake, 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 number 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, which may be printed using uulog -D.

       -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.
