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
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
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 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 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 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, 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 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.
