27# Storage backend for quotas
28# only PGStorage (PostgreSQL) and LDAPStorage (OpenLDAP) are supported.
29# MySQL and BerkeleyDB are planned.
30
31# the 'postgresql' value is deprecated, use 'pgstorage' instead.
32storagebackend: pgstorage
33
34# Quota Storage Server hostname (and optional port)
35# e.g. db.example.com:5432
36storageserver: localhost
37
38#
39# name of the Quota Storage Database
40storagename: pykota
41
42#
43# Quota Storage normal user's name and password
44# These two fields contain a username and optional password
45# which may give readonly access to your print quota database.
46#
47# PLEASE ENSURE THAT THIS USER CAN'T WRITE TO YOUR PRINT QUOTA
48# DATABASE, OTHERWISE ANY USER WHO COULD READ THIS CONFIGURATION
49# FILE COULD CHANGE HIS PRINT QUOTA.

52# storageuserpw: Comment out if unused, or set to Quota Storage user password

54# Should the database caching mechanism be enabled or not ?
55# If unset, caching is disabled. Possible values Y/N/YES/NO
56# caching mechanism works with both PostgreSQL and OpenLDAP backends
57# but may be really interesting only with OpenLDAP.
58#
59# ACTIVATING CACHE MAY CAUSE PRECISION PROBLEMS IN PRINT ACCOUNTING
60# IF AN USER PRINTS ON SEVERAL PRINTERS AT THE SAME TIME.
61# YOU MAY FIND IT INTERESTING ANYWAY, ESPECIALLY FOR LDAP.
62#
63# FYI, I ALWAYS SET IT TO YES !
64#
65storagecaching: No
66
67# Should full job history be disabled ?
68# If unset or set to No, full job history is kept in the database.
69# This will be useful in the future when the report generator
70# will be written.
71# Disabling the job history can be useful with heavily loaded
72# LDAP servers, to not make the LDAP tree grow out of control.
73# Disabling the job history with the PostgreSQL backend works too
74# but it's probably less useful than with LDAP.
75disablehistory: No
76
77# LDAP example, uncomment and adapt it to your own configuration :
78#storagebackend: ldapstorage
79#storageserver: ldap://ldap.librelogiciel.com:389
80#storagename: dc=librelogiciel,dc=com
81#storageuser: cn=notadmin,dc=librelogiciel,dc=com
82#storageuserpw: abc.123
83#
84# Here we define some helpers to know where
85# to plug into an existing LDAP directory
86#userbase: ou=People,dc=librelogiciel,dc=com
87#userrdn: uid
88#balancebase: ou=People,dc=librelogiciel,dc=com

98#
99# How to create new accounts and groups
100# authorized values are "below" and "attach(objectclass name [, fail|warn])"
101#
102# "below" creates the new accounts/groups as standalone entries
103# below the above defined 'userbase' ou
104#
105# attach(objectclass name [, action]) tries to find some existing user/group
106# using the above defined 'userrdn' or 'grouprdn' and 'userbase'
107# 'groupbase', and attach the PyKota specific entries to it.
108# if action is "warn" and no entry exists to attach to, a new
109# entry is created, and a message is logged.
110# if action is "fail" and no entry exists to attach to, program
111# logs an error message and aborts.
112# if action is not set, the default value is "fail".
113#
114# a possible value:  newuser: attach(posixAccount, warn)
115#newuser : below
116#newgroup : below
117#
118# LDAP attribute which stores the user's email address
119#usermail : mail
120
121#
122# Choose what attribute contains the list of group members
123# common values are : memberUid, uniqueMember, member
124#groupmembers: memberUid
125
126# Activate low-level LDAP cache yes/no
127# Nothing to do with "storagecaching" which is higher level
128# and database independant.
129# This saves some search queries and may help with heavily
130# loaded LDAP servers.
131# This is EXPERIMENTAL.
132#
133# BEWARE : SETTING THIS TO 'YES' CAUSES PROBLEMS FOR NOW
134# BETTER TO LET IT SET TO 'NO'
135ldapcache: no
136
137# Where to log ?
138# supported values : stderr, system (system means syslog, but don't use 'syslog' here)
139# if the value is not set then the default SYSTEM applies.
140logger: system
141
142# Enable debugging ? Put YES or NO there.
143# From now on, YES is the default in this sample
144# configuration file, so that debugging is activated
145# when configuring PyKota. After all works, just
146# put NO instead to save some disk space in your
147# logs.
148# Actually only database queries are logged.
149debug : Yes
150
151# Mail server to use to warn users
152# If the value is not set then localhost is used.
153smtpserver: localhost
154
155# Crash messages' recipient : in addition to the log files
156# each software crash can be sent to the author of PyKota
157# or any other person of your choice. By default this
158# is disabled. The recipient pykotacrashed@librelogiciel.com
159# reaches PyKota's author.
160# The 'adminmail' (defined a bit below) is CCed.
161#
162# Privacy concerns : what is sent is only :
163#
164#        - a copy of the software's traceback
165#        - a copy of the software's command line arguments
166#        - a copy of the software's environment variables
167#
168# suggested value
169# crashrecipient: pykotacrashed@librelogiciel.com
170
171# Email domain
172# If the value is not set, and the mail attribute for the user
173# is not set in the PyKota storage, be it LDAP (see usermail directive
174# above) or PostgreSQL, then email messages are sent to
175# username@smtpserver
176#
177# If the value is set, then email messages are sent to
178# username@maildomain using the SMTP server defined above
179#
180# Set the appropriate value below, example.com set as per RFC2606.
181maildomain: example.com
182
183# Should we force usernames to be all lowercase when printing ?
184# Default is No.
185# This is a global option only.
186# Some people reported that WinXP sends mixed case usernames
187# setting 'utolower: Yes' solves the problem.
188# Of course you have to user lowercase only when adding
189# users with edpykota, because ALL database accesses are
190# still case sensitive.
191#
192# If utolower is Yes, the usernames received from the printing
193# system is converted to lowercase at the start of the cupspykota
194# backend or of the pykota filter.
195#
196# If utolower is No, which is the default, strict case checking
197# is done, this means that users 'Jerome' and 'jerome' are
198# different. Printer and groups names are ALWAYS case sensitive.
199utolower: No
200
201# What is the accounting backend to use
202#
203# supported values :
204#
205#    - hardware : asks the printer for its lifetime page counter
206#                 via either SNMP, AppleTalk, or any external
207#                 command. This method is the method used by
208#                 default in PyKota since its beginning.
209#
210#                 In the lines below "%(printer)s" is automatically replaced
211#                 at run time with your printer's Fully Qualified Domain Name
212#                 for network printers.
213#                 e.g. myprinter.example.com
214#
215#         Example :
216#         
217#             accounter: hardware(/usr/bin/snmpget -v1 -c public -Ov %(printer)s mib-2.43.10.2.1.4.1.1 | cut -f 2,2 -d " ")
218#         
219#         Another untested example, using npadmin :
220#         
221#             accounter: hardware(/usr/bin/npadmin --pagecount %(printer)s)
222#         
223#         Another example, for AppleTalk printers which works fine :
224#         (You may need the pap CUPS backend installed, and copy the
225#         pagecount.ps file from untested/netatalk into /etc or any
226#         appropriate location)
227#         
228#             accounter: hardware(/usr/share/pykota/papwaitprinter.sh "MyPrinter:LaserWriter@*" && /usr/bin/pap -p "MyPrinter:LaserWriter@*" /usr/share/pykota/pagecount.ps  2>/dev/null | /bin/grep -v status | /bin/grep -v Connect | /usr/bin/tail -1)
229#         
230#         An example for parallel printers like the HP Laserjet 5MP :
231#         
232#             accounter: hardware(/bin/cat /usr/share/pykota/pagecount.pjl >/dev/lp0 && /usr/bin/head -2 </dev/lp0 | /usr/bin/tail -1)
233#         
234#         This value can be set either globally or per printer or both.
235#         If both are defined, the printer option has priority.
236#         
237#         Some examples and comments provided by Bob Martel from csuohio.edu
238#         
239#         For several printers I could not get the page count using snmpget.  I
240#         resorted to snmpwalk:
241#         
242#             accounter: hardware(/opt/local/net-snmp/bin/snmpwalk -v 1 -Cc -c public %(printer)s | grep mib-2.43.10.2.1.4.1.1 | cut -d " " -f4)
243#         
244#         The last example is still more ugly, some of the printers only provided
245#         their counters without names, but at least always on the same line:
246#         
247#             accounter: hardware(/opt/local/net-snmp/bin/snmpwalk -v 1 -Cc -c public -Ov %(printer)s | grep Counter32 | tail -2 | head -1 | cut -d " " -f2)
248#         
249#         An example using netcat and a preformatted PJL job which you can find
250#         in the untested/pjl directory, which is sent to a JetDirect print
251#         server on port 9100 :
252#         
253#             accounter: hardware(/bin/nc -w 2 %(printer)s 9100 </usr/share/pykota/pagecount.pjl | /usr/bin/tail -2)
254#         
255#         An example using the contributed pagecount.pl script which does
256#         the same as above, but should work on more printers :
257#         
258#             accounter: hardware(LC_ALL=C /usr/share/pykota/pagecount.pl %(printer)s 9100)
259#         
260#         NB : the LC_ALL=C is used because sometimes Perl can correctly set locale and is verbose
261#              about it, causing PyKota to miss the correct answer.
262#
263#         WARNING : In any case, when using an hardware accounter, please test the command line outside
264#                   of PyKota before. This will save you some headaches in case it doesn't work as expected.
265#         
266#         The waitprinter.sh is there to wait until the printer is idle again.
267#         This should prevent a job to be sent to the printer while another one is
268#         not yet finished (not all pages are printed, but the complete job is in
269#         the printer)
270#         
271#         YOU ABSOLUTELY HAVE TO BE SURE YOU HAVE A SCRIPT WHICH WAITS FOR THE
272#         PRINTER BEING READY BEFORE ASKING FOR ITS INTERNAL PAGE COUNTER.
273#         
274#         PYKOTA INCLUDES SUCH SCRIPTS FOR SNMP AND APPLETALK PRINTERS, MORE TO COME
275#
276#         SOME OF THE ABOVE EXAMPLES DON'T USE SUCH A SCRIPT, YOU HAVE BEEN WARNED
277#         
278#
279#    - software : delegates the job's size computation to any
280#                 external command of your choice.
281#
282#                 best choice for this is probably to set it
283#                 this way :
284#
285#                   accounter: software(/usr/bin/pkpgcounter)
286#
287#                 pkpgcounter is a command line tool which is
288#                 part of PyKota and which can handle both
289#                 DSC compliant PostScript, PCL5, PCL6 (aka PCLXL)
290#                 and PDF documents. More file formats will be added
291#                 in the future, as time permits.
292#
293#                 while pkpgcounter is the recommended value
294#                 you can use whatever command you want provided
295#                 that your command accepts the job's data on its
296#                 standard input and prints the job's size in pages
297#                 as a single integer on its standard output.
298#
299# This value can be set either globally or on a per printer basis
300# If both are defined, the printer option has priority.
301#
302# default value
303accounter: hardware(/usr/share/pykota/waitprinter.sh %(printer)s && /usr/bin/snmpget -v1 -c public -Ov %(printer)s mib-2.43.10.2.1.4.1.1 | cut -f 2,2 -d " ")

310# and the default adminmail root@localhost are used.
311admin: John Doe
312adminmail: root@localhost
313
314#
315# Who should we send an email to in case a quota is reached ?
316# possible values are : DevNull, User, Admin, Both, External(some command)
317# The Both value means that the User and the Admin will receive
318# an email message.
319# The DevNull value means no email message will be sent.
320# This value can be set either globally or per printer or both.
321# If both are defined, the printer option has priority.
322# If the value is not set, then the default BOTH applies.
323#
324#   Format of the external syntax :
325#
326#       mailto: external(/usr/bin/mycommand >/dev/null)
327#
328#   You can use :
329#
330#       '%(action)s'            will contain either WARN or DENY
331#       '%(username)s'          will contain the user's name
332#       '%(printername)s'       will contain the printer's name
333#       '%(email)s'             will contain the user's email address
334#       '%(message)s'           will contain the message if you want
335#                               to use it.
336#
337#   On your command line, to pass arguments to your command.
338#   Example :
339#
340#       mailto: external(/usr/bin/callpager %(username)s "Quota problem on %(printername)s" >/dev/null)
341#
342#   To automatically send a WinPopup message (this may only work with a PDC,
343#   here the same machine does Samba as PDC + CUPS) :
344#
345#       mailto: external(echo "%(message)s"  | /usr/bin/iconv --to-code utf-8 --from-code iso-8859-15 | /usr/bin/smbclient -M "%(username)s" 2>&1 >/dev/null)
346#
347#   NB : I use ISO-8859-15, but Windows expects UTF-8, so we pipe the message
348#        into iconv before sending it to the Windows user.
349#
350# or more simply :
351#
352#       mailto: external(/usr/share/pykota/mailandpopup.sh %(username)s %(printername)s "%(email)s" "%(message)s" 2>&1 >/dev/null)
353#
354#   NB : The mailandpopup.sh shell script is now included in PyKota
355#
356#   NB : in ANY case, don't forget to redirect your command's standard output
357#        somewhere (e.g. >/dev/null) so that there's no perturbation to the
358#        underlying layer (filter or backend)
359#
360mailto: both

363# Grace delay in days
364# This value can be set either globally or per printer or both.

375# This option can only appear in the global section
376poorman: 2.0
377
378# Poor man's warning message
379# The warning message that is sent if the "poorman" value is reached

385# The warning message that is sent if the soft quota limit is reached
386# May appear either globally or on a per-printer basis
387softwarn: Your Print Quota Soft Limit is reached.
388 This means that you may still be allowed to print for some
389 time, but you must contact your administrator to purchase
390 more print quota.

421#
422# external policy can be used to launch any external command of your choice,
423# for example to automatically add the user to the quota storage

429#
430#   policy: external(/usr/local/bin/myadminscript.sh %(username)s >/dev/null)
431
432# You can use :

467# PYKOTAACTION : ALLOW or DENY or WARN for current print job
468# PYKOTAUSERNAME : user's name
469# PYKOTAPRINTERNAME : printer's name

520#
521# Enforcement can be defined either globally, per printer,
522# or both. If both are defined, the printer specific enforcement
523# setting has priority.
524#
525# valid values : "strict" or "laxist"
