CAVEAT:
uupoll as well as autopoll are created, tested and run on 
a NeXT running NeXTstep 2.1+ only! Autopoll will take the same arguments
as uucico and may well work with them the same way uucico works but it
has only been tested to call uucico with the options:
X
X -s<site> -S<site> -f -r1 -C -D (as well as the long form of these options) 
X
so far. All options given to autopoll will be passed verbatim to uucico.
X
DESCRIPTION:
The program uupoll was created to be a full replacement for the vendor
supplied one on a NeXT computer. That uupoll checked any site name against
the "hardwired" L.sys and did end with a "Bus error" if the site could not
be found. There was no source available to modify so it had to be created
from scratch.
The program autopoll has no equivalent an the NeXT. The intentions behind
it was to automate the task of rescheduling any failed call. It may be
started by an entry in the crontab tables in just the same way uucico is
started (it will start uucico):
X
05 5 * * *       uucp  /usr/local/lib/uucp/autopoll -r1 >>/tmp/poll.log 2>&1
X
Any messages go to stderr or a file (if compiled with that option); in case
the file could not be opened it will use stdout to tell you just that and quit.
To catch any output one may place the string
X
X  >>/tmp/poll.log 2>&1
X
into the command line as well. Uupoll as well as autopoll will place only
a start message into the logfiles in case they are invoked manually from
the shell.
If the call fails autopoll will reschedule uucico for a later time by means
of an AT job.
The messages given by uupoll and autopoll carry an indicator to inform about
the nature of an error; they are:
X
- (I) informal message; such as ".. started" ".. ended".
- (W) there might be an error but the program decided to go ahead.
X      The exit code will be at least 4.
- (E) a severe error was encountered that either aborts the whole run or
X      only the task for one site will be aborted. 
X      The exit code will be at least 8.
- (C) a catastrophic error has been found such as unable to fork. The run
X      is aborted.
X      The exit code will be at least 16.
The final message will show the exit code the programm has terminated with.
X
For more information see the man pages or look into the source.
X
INSTALLATION:
all files should be placed in one folder. Then examine and change the files
Makefile and conf.h to meet your needs. To compile uupoll some files of
uucp must be available (see Makefile: uucpsrcs)
If not already there change to the directory which contain the files and type:
X
make
X
this should compile UUPOLL and AUTOPOLL. There should only be a warning
that rcsid is defined but not used.
Before actually installing you should test the programs to be working as
desired.
Then check the Makefile for the final placement of the modules and the man
pages. Make sure the ownership and setuid is what you need on your machine
to run the program(s).
Then su to root and type:
X
make install
X
which should install the above programs and the man pages in the appropriate
directories.
Some word on the coding: have mercy! This is my second project in 'C'; any
suggestions that may improve the style/coding are welcome however.

.UC 6
.SH NAME
autopoll \- automatic \s-1UUCP\s+1 file transfer supervisor
.SH SYNOPSIS
.B autopoll
[
.BI options
]
.SH DESCRIPTION
file transfer requests placed by
.IR uucp (1)
or
.IR uux (1)
are handled by
.IR uucico (8C).
.IR uucico
will be invoked immediately by the above programs unless the \-r
option is given which queues the request for later processing. This
is typically done by entries in the
.IR crontab
table(s) which will invoke
.IR uucico.
.IR uucico
can also be invoked by
.IR uupoll (8C).
All methods have in common that there is no automatic retry by
.IR uucico
itself in case the call failed for some reason.
Either manual
intervention or some sort of scripts must be used to overcome this
limitation.
.PP
.IR Autopoll
can be used to automate up to a certain degree the task of rescheduling
a call. None of the standard programs already mentioned need to be 
modified to get this working. Also not recommended (see BUGS section)
.IR uucico
may be an alias to 
.IR autopoll
as all arguments passed to
.IR autopoll
will be copied verbatim to
.IR uucico.
In case this is done by link or other means the original
.I uucio
must still be available in a directory outside of the normal search path
otherwise
.I autopoll
can't do what it's intended to do and will form a loop.
.PP
When
.IR autopoll
is called thre will be a check on the \-s, \-S and \-f option to
see whether this
is a specific call or not. Also the \-S and the \-f option must be checked
to determine the type of call: honor any imposed wait for a site or not.
Any call to ourself or to an unknown site will be refused. The known sites
will be obtained by a call to
.IR uuname(1).
All other options will not be checked in any way. Next to this
.IR uucico
is called and the exit code is checked for a `1' which indicates that the call
failed for some reason whatsoever. A `0' exit code will be interpreted as
a success and
.IR autopoll
ends immediate. If the call seems to be unsuccessful a new call is scheduled
for any site whose .Status files have a retry period greater than 0. The
retry will be scheduled by means of placing an
.IR at
job at the time of the failing call plus any wait time given. For those
sites that have been called with either the \-f or \-S option the retry
time will be the time of the failing call plus 120 seconds.
.PP
In case the time calculated from the values found in a \.Status file is
lower than the current time, the current time plus 60 seconds will be taken
as the retry time. 
.PP
A site will
.IR not
be automatically called again if one of the following
conditions is met:
.PP
\-
.IR uucico
is terminated by a signal
.PP
\- either fork() or exec() failed
.PP
\- the
.IR at
command failed for any reasons.
.PP
\- if no wait should be honored and the retry time is found to be zero.
(this may indicate a `Wrong time to call' condition.
.PP
There are other circumstances that may lead to not reschedule a call or
not to call
.IR uucico
at all, all of which should be accompanied by (a) self explanatory message(s).
.SH BUGS
\- invalid options will make
.IR uucico
fail. The exit code for this type is the same as for any other failure; this
can reschedule the call over and over again or never.
.PP
\- 
.IR autopoll
may not work as expected when called with options other than \-r1, \-s,
\-S or \-f.
.PP
\- a rescheduled call may fail with `wrong time to call' the second time
but will be rescheduled again. The times to call won't be checked by
.IR autopoll
and the .Status file may not indicate this in case the \-c option is given.
.PP
\- in case the ..._DIR points to an invalid file a `Bus error' my pop up
during the `exec' call.
.PP
\- the `chat-timeout' value may have to be increased when using
.IR autopoll.
An indication to do that is that the call fails short after `CONNECT'
has been received with `Time out in chat script'.
.PP
\- the site names given will be checked aginst the output of
.I uuname
without any alias expansion done.
.PP
\- the text strings whithin the \.Status files will not be used to detect
a failing call.

X              your image to be a good programmer.
X
X   Function: Autopoll may be called just as uucico is called. The difference
X             is that autopoll will call uucico and if the return code is
X             not zero a check is made on the status files to see which site's
X             call failed. Those sites will be called again at that time found
X             in the status file plus any imposed wait. The next call will be
X             scheduled via an at job which in turn is handled by cron. 
X             Atrun depends on the scheduling granularity of cron so the
X             actual times may be later than planned.  
X             Autopoll will check the options -f and -s (-S) as well as the name
X             of the site passed. All other options will be passed unchecked.
X             The -f and -S options will indicate to autopoll that any wait
X             to call a site should be ignored; if the call fails the next
X             call to those sites will be at the current time plus 120 secs.
X             When the time found plus any wait evaluates to a time that 
X             passed already the next call will be the current time plus 60
X             secs. The name of the site if given must be a valid one and not
X             the host itself otherwise it will be ignored.
X  
X   Call:     autopoll [ options ]
X
X                      all option that apply to uucico may be given and
X                      will be passed verbatim. See man uucico(8).
X             
X   Environment: NeXT 2.1+, Taylor UUCP-1.04+
X   
X   I/O:         stdin: unused.
X                stdout: used only when ALOG_DIR is defined and the file
X                        can't be opened. It will be a single message to tell
X                        just that and the run is aborted.
X                stderr: all messages go here.
X                        If ALOG_DIR is defined (see conf.h) all messages will
X                        be appended to a file autopoll.msglog in that 
X                        directory; the file will be created automatically if
X                        necessary; a redirection is then no longer possible. 
X                Needs access to .Status files (see Comments later on).
X
X   Called Programs: sort, uniq, uucico, uuname, at
X
X   Compile:     no special options are needed. Compiled with gcc 2.3.3 -O2.
X                Compile with the supplied cc might produce erroneous code
X                for the check options switch case 's' code: the break inside
X                the first if (..) {... break} is ignored.
X
X   Comments:    - should run setuid UUCP or whatever userid is necessary to
X                  access (RDONLY) the .Status files and to run the programs
X                  named under "Called Programs" above.
X                - No alias expansion is done on the given names for the
X                  check against uuname's output..
X                - Invalid arguments will yield in an exit code > 0 as do
X                  "normal" failures. It may therefore happen that a site
X                  is called at the intervals with the same invalid arguments.
X                - "Wrong time to call" is not handled properly and may 
X                  call the site at the intervals until the time ban is lifted.
X                - human action is necessary as we can't distinguish between
X                  "normal" failures and "errors" such as wrong password,
X                  number to dial etc. The logs should be checked periodically.
X                - if CICO_DIR points to a non existent program the run may
X                  end with signal 10: Bus Error.
X                - is has been observed that uucico will time out with "Dial
X                  failed" when called via autopoll; setting chat-timeout to
X                  value of 40 cured that problem.
X                - no rescheduling is done in case uucico fails and this
X                  is not reported in the .Status file, one should check
X                  the uucico log; this is to the fact that autopoll will
X                  not scan the uucico log.

.SH NAME
uupoll \- poll a remote \s-1UUCP\s+1 site
.SH SYNOPSIS
.B uupoll
[
.BI \-g grade
] [
.B \-n
] [
.B \-x
]
.I system ... ...
.SH SUMMARY
This version of
.IR uupoll
can be used to fully replace the vendor supplied
.IR uupoll
that comes with the NeXTStep OS. The original version (up to 3.1) had a
X bug in that
X an unknown site given as argument would yield in a `Bus error' condition.
Using any other type of UUCP like Taylor-UUCP with the option of having
a different file structure as well as a different L.sys will therefore 
make it necessary to do maintenance to the (unused) L.sys as well to keep
.IR uupoll
going. This one has been programmed from scratch due to the fact that no 
source code was available. Some enhancements have been incorporated into
this version:
.PP
\- the default grade may now be compiled different from `A'.
.PP
\- the options may now be given in any order and the \-g option may be given
more than once. Any option will be used immediately when encountered and
will stay in effect unless reset; this does not apply to the \-x and \-n
option which can't be reset. The processing of options is guaranteed to be
from left to right so that some grouping may be achieved (see below).
.PP
\-
.IR uupoll
may be used to call any program instead of
.IR uucico
namely
.IR autopoll
to ease the task of rescheduling a failed call. 
.SH DESCRIPTION
.I Uupoll
is used to force a poll of a remote system. It queues a null job for the
remote system, unless the \-x option has been given, and then invokes
either
.IR uucico (8C)
or
.IR autopoll (8C)
or any other program depending on how
.IR uupoll
is customized. If used in conjunction with
.IR autopoll
the latter will then invoke
.IR uucico.
.SH OPTIONS
The following options are available:
.TP 8
.BI \-g grade
Only send jobs of grade
.I grade
or higher on this call. The
.I grade
stays in effect until it is changed by a different \-g option. 
.TP 8
.B \-n
Queue the null job, but do not invoke the program that actually calls
the named site(s).
The \-n option once given will apply to all sites following to the
.IR right
of it.
.TP 8
.B \-x
Do not place a null job for all following sites. This option must be given
before the \-n option. The \-n option will nullify this. Any grade in effect
will not be honored because
.I uucico (Taylor)
does not carry the \-g option at the moment.
.PP
.I Uupoll
is usually run by
.IR cron (5)
or by a user who wants to hurry a job along. A typical entry in
.I crontab
could be:
.PP
.nf
X	0	0,8,16	*	*	*	uucp /usr/bin/uupoll ihnp4
X	0	4,12,20	*	*	*	uucp /usr/bin/uupoll ucbvax
.fi
This will poll
.B ihnp4
at midnight, 0800, and 1600, and
.B ucbvax
at 0400, noon, and 2000.
.PP
If the local machine is already running
.I uucico
every
hour and has a limited number of outgoing modems, a better approach
might be:
.PP
.nf
X	0	0,8,16	*	*	*	uucp /usr/bin/uupoll -n ihnp4
X	0	4,12,20	*	*	*	uucp /usr/bin/uupoll -n ucbvax
X	5	*		*	*	*	uucp /usr/lib/uucp/uucico -r1 -D -C
.fi
This will queue null jobs for the remote sites at the top of the hour; they
will be processed by
.I uucico
when it runs five minutes later (the -C option apply to Taylor
uucp-1.05 only, the -D option applies to Talor uucp-1.04 and up)
.SH EXTENDED options
An example of the options and how they interact is given below. The working
order while processing the options is left to right:
.nf
X    uupoll -gC site1 -gB site2 -x site3 -n -gA site4 site5
.fi
.PP
this poll will:
.PP
- call immediate site1 with grade C or higher and will place a null job
.PP
- call immediate site2 with grade B or higher and will place a null job
.PP
- call immediate site3 with grade B or higher without placing a null job
.PP
- just placing a null job for site4 and site5 with grade A or higher. These
sites will be called at the next regular schedule.
.SH BUGS
When more than one site is given on the command line and no \-n option is
given there will be an immediate invocation of
.IR uucico
or
.IR autopoll
for
.IR all
sites given. That may lead to a `No port available' condition.

X
X   Funktion: The main intention behind this program was to get a full
X             replacement of the uupoll supplied by NeXT when using an
X             UUCP or a file structure that is different from that hardwired
X             config in NeXT's uupoll. The lack of source made it impossible
X             to modify the supplied uupoll.
X  
X   Call:     uupoll [-n] [-x] [-g[A | 0-9,A-Z,a-z]] site ...
X             
X                    -n    just place a poll file but do not call uucico;
X                          This option can be given only once.
X                    -x    meaningful only for sites not affected by the -n
X                          option. It prevents the creation of a poll file; 
X                          the default is to place one. In case the poll fails 
X                          there will be no attempt to poll those sites on 
X                          the next general (unspecific) poll. If using 
X                          autopoll the site will be called at the next + 1
X                          run of autopoll.
X                    -g    any grade may be given to meet the criteria for
X                          a successful poll. The default being specified
X                          in conf.h (A).
X                          This option may be given individually for each
X                          site to call.
X                    site  the name of the site to be called. As many sites
X                          as necessary may be specified separated by at least
X                          one blank.
X             Note: any site will be called with the options currently in
X                   effect. The working order is left to right. Example:
X                   uupoll -gQ site1 site2 -gZ site3 -n site4
X                   site1 and site2 will be called immediate with grade Q
X                   site3 will be called immediate with grade Z. Site4 will
X                   have a poll file created with grade Z.
X
X   Environment: NeXT 2.1
X
X   Called Programs: sort, uniq, uucico (or autopoll), uuname
X
X   Compile:     no special options are needed
X
X   Comments:    - should run setuid UUCP or whatever userid is necessary to
X                  write to the spool directory with the proper ownership of
X                  the files and to run uucico.
X                - No alias expansion is done on the given names.
