NAME    [Toc]    [Back]

       uucico  -  Transfers uucp command, data, and execute files
       to remote systems

SYNOPSIS    [Toc]    [Back]

       uucico [-r role_number] [-x debug_level] [-s system_name]

OPTIONS    [Toc]    [Back]

       Valid values for role_number are: 1 for server mode and  0
       (zero)  for  client mode.  The default is 0.  If uucico is
       started manually, set this option to 1.   Displays  debugging
 information on the screen of the local terminal.  The
       valid range for debug_level is 0 to  9.   The  higher  the
       number,  the  more detailed the final report.  This option
       is useful in  correcting  problems  with  the  expect_send
       sequence in the Systems file.  The name of the remote system.
  Use only when starting uucico  manually.   The  system_name
  is  supplied  internally  when uucico is started

              Note that system  names  must  contain  only  ASCII

DESCRIPTION    [Toc]    [Back]

       The  uucico  daemon  transports  uucp  Command (C.*), Data
       (D.*), and Execute (E.*)  files that are  created  by  the
       uucp  and  uux commands to a specified remote system. Both
       the local and remote systems run the  uucico  daemon,  and
       the   daemons  on  the  two  systems communicate with each
       other to complete transfer requests.

       The uucico daemon performs the  following  actions:  Scans
       the  spooling  directory  (/usr/spool/uucp/system_name) on
       the local  system  for  transfer  requests.   Selects  the
       device used for the communications connection after checking
 the /usr/lib/uucp/Devices file and the lock  files  in
       the  /var/spool/locks  directory.   Places  a  call to the
       specified remote system using information in the  Systems,
       Dialers,  and Dialcodes files located in the /usr/lib/uucp
       directory.  Performs the required login sequence specified
       in  the  Systems  file.   Checks permissions listed in the
       /usr/lib/uucp/Permissions file.  Checks scheduling  limits
       in  the  Maxuuscheds  and  Maxuuxqts  files located in the
       /usr/lib/uucp directory.  Runs all transfer requests  from
       both  the  local and the remote system, placing the transferred
 files in the public  directories  (/usr/spool/uucppublic/*).
   Logs  transfer  requests  and  completions in
       files in the /usr/spool/uucp/.Log/uucico directory.  Notifies
 specified users of transfer requests.

       Usually  the  uucico  daemon is called by the uucp and uux
       commands when needed, and is started periodically  by  the
       uucp  scheduling  daemon, uusched, which is started by the
       cron daemon.

       The uucico daemon can be started from the command line for
       debugging.  The uucp command uutry also starts uucico with
       debugging turned on.

       In the case of a uux command request for the execution  of
       a  command on a remote system, the uucico daemon transfers
       the files, and the uuxqt daemon executes  the  command  on
       the remote system.

EXAMPLES    [Toc]    [Back]

       To  start  the  uucico  daemon  from the command line as a
       background process and contact  the  remote  system  hera,

              /usr/lib/uucp/uucico -r 1 -s hera & To debug uucico
              connections, start the uucico daemon  with  the  -x
              option, and enter:

              /usr/lib/uucp/uucico -r 1 -s venus -x 9


       The  following  environment variables affect the execution
       of uucico: Specifies the flow control used on the  connection.
  Permitted values are: HW (hardware), SW (software),
       HSW (hardware and software), and NONE. The uugetty on  the
       remote system must also use the same flow control.  Specifies
 the amount of time (in seconds) for uucico to try  to
       establish  a connection before it times out.  A value of 0
       (zero) indicates an unlimited amount of time.

       uucico daemon Command files Data files Execute files  Contains
  files  after transfer by the uucico daemon Contains
