UUQ(1C)UUQ(1C)NAME
uuq - examine or manipulate the uucp queue
SYNOPSIS
uuq [ -l ] [ -h ] [ -ssystem ] [ -uuser ] [ -djobno ] [ -rsdir ] [ -bbaud ]
DESCRIPTION
Uuq is used to examine (and possibly delete) entries in the uucp queue.
When listing jobs, uuq uses a format reminiscent of ls. For the long format, information for each job listed includes job number, number
of files to transfer, user who spooled the job, number of bytes to send, type of command requested (S for sending files, R for receiving
files, X for remote uucp), and file or command desired.
Several options are available:
-h Print only the summary lines for each system. Summary lines give system name, number of jobs for the system, and total number of
bytes to send.
-l Specifies a long format listing. The default is to list only the job numbers sorted across the page.
-ssystem Limit output to jobs for systems whose system names begin with system.
-uuser Limit output to jobs for users whose login names begin with user.
-djobno Delete job number jobno (as obtained from a previous uuq command) from the uucp queue. Only the UUCP Administrator is permitted
to delete jobs.
-rsdir Look for files in the spooling directory sdir instead of the default directory.
-bbaud Use baud to compute the transfer time instead of the default 1200 baud.
FILES
/usr/spool/uucp/ Default spool directory /usr/spool/uucp/C./C.* Control files
/usr/spool/uucp/Dhostname./D.* Outgoing data files /usr/spool/uucp/X./X.* Outgoing execution files
SEE ALSO uucp(1C), uux(1C), uulog(1C), uusnap(8C)BUGS
No information is available on work requested by the remote machine.
The user who requests a remote uucp command is unknown.
Uuq -l can be horrendously slow.

UUCICO(8) System Manager's Manual UUCICO(8)NAME
uucico, uucpd - transfer files queued by uucp or uux
SYNOPSIS
/usr/sbin/uucico [ -dspooldir ] [ -ggrade ] [ -rrole ] [ -R ] [ -ssystem ] [ -xdebug ] [ -L ] [ -tturnaround ]
/usr/libexec/uucpd
DESCRIPTION
Uucico performs the actual work involved in transferring files between systems. Uucp(1) and uux(1) merely queue requests for data transfer
which uucico processes.
The following options are available.
-dspooldir
Use spooldir as the spool directory. The default is /usr/spool/uucp.
-ggrade Only send jobs of grade grade or higher this transfer. The grade of a job is specified when the job is queued by uucp or uux.
-rrole role is either 1 or 0; it indicates whether uucico is to start up in master or slave role, respectively. 1 is used when running
uucico by hand or from cron(8). 0 is used when another system calls the local system. Slave role is the default.
-R Reverse roles. When used with the -r1 option, this tells the remote system to begin sending its jobs first, instead of waiting for
the local machine to finish.
-ssystem
Call only system system. If -s is not specified, and -r1 is specified, uucico will attempt to call all systems for which there is
work. If -s is specified, a call will be made even if there is no work for that system. This is useful for polling.
-xdebug Turn on debugging at level debug. Level 5 is a good start when trying to find out why a call failed. Level 9 is very detailed.
Level 99 is absurdly verbose. If role is 1 (master), output is normally written to the standard message output stderr. If stderr
is unavailable, output is written to /usr/spool/uucp/AUDIT/system. When role is 0 (slave), debugging output is always written to
the AUDIT file.
-L Only call ``local'' sites. A site is considered local if the device-type field in L.sys is one of LOCAL, DIR or TCP.
-tturnaround
Use turnaround as the line turnaround time (in minutes) instead of the default 30. If turnaround is missing or 0, line turnaround
will be disabled. After uucico has been running in slave role for turnaround minutes, it will attempt to run in master role by
negotiating with the remote machine. In earlier versions of uucico, a transfer of many large files in one direction would hold up
mail going in the other direction. With the turnaround code working, the message flow will be more bidirectional in the short
term. This option only works with newer uucico's and is ignored by older ones.
If uucico receives a SIGFPE (see kill(1)), it will toggle the debugging on or off.
Uucpd is the server for supporting uucp connections over networks. Uucpd listens for service requests at the port indicated in the
``uucp'' service specification; see services(5). The server provides login name and password authentication before starting up uucico for
the rest of the transaction.
Uucico is commonly used either of two ways: as a daemon run periodically by cron(8) to call out to remote systems, and as a ``shell'' for
remote systems who call in. For calling out periodically, a typical line in crontab would be:
0 * * * * /usr/sbin/uucico -r1
This will run uucico every hour in master role. For each system that has transfer requests queued, uucico calls the system, logs in, and
executes the transfers. The file L.sys(5) is consulted for information about how to log in, while L-devices(5) specifies available lines
and modems for calling.
For remote systems to dial in, an entry in the passwd(5) file must be created, with a login ``shell'' of uucico. For example:
nuucp:Password:6:1::/usr/spool/uucppublic:/usr/sbin/uucico
The UID for UUCP remote logins is not critical, so long as it differs from the UUCP Administrative login. The latter owns the UUCP files,
and assigning this UID to a remote login would be an extreme security hazard.
