[global]
# Storage backend for quotas
# only PGStorage (PostgreSQL) and LDAPStorage (OpenLDAP) are supported.
# MySQL and BerkeleyDB are planned.

# the 'postgresql' value is deprecated, use 'pgstorage' instead.
storagebackend: pgstorage

# Quota Storage Server hostname (and optional port)
# e.g. db.example.com:5432
storageserver: localhost

#
# name of the Quota Storage Database
storagename: pykota

# 
# Quota Storage normal user's name and password
# These two fields contain a username and optional password 
# which may give readonly access to your print quota database.
# 
# PLEASE ENSURE THAT THIS USER CAN'T WRITE TO YOUR PRINT QUOTA
# DATABASE, OTHERWISE ANY USER WHO COULD READ THIS CONFIGURATION
# FILE COULD CHANGE HIS PRINT QUOTA.
#
storageuser: pykotauser
# storageuserpw: Comment out if unused, or set to Quota Storage user password

# Should the database caching mechanism be enabled or not ?
# If unset, caching is disabled. Possible values Y/N/YES/NO
# caching mechanism works with both PostgreSQL and OpenLDAP backends
# but may be really interesting only with OpenLDAP.
#
# ACTIVATING CACHE MAY CAUSE PRECISION PROBLEMS IN PRINT ACCOUNTING
# IF AN USER PRINTS ON SEVERAL PRINTERS AT THE SAME TIME.
# YOU MAY FIND IT INTERESTING ANYWAY, ESPECIALLY FOR LDAP.
#
# FYI, I ALWAYS SET IT TO YES !
#
storagecaching: No

# Should full job history be disabled ?
# If unset or set to No, full job history is kept in the database.
# This will be useful in the future when the report generator
# will be written.
# Disabling the job history can be useful with heavily loaded
# LDAP servers, to not make the LDAP tree grow out of control.
# Disabling the job history with the PostgreSQL backend works too
# but it's probably less useful than with LDAP.
disablehistory: No

# LDAP example, uncomment and adapt it to your own configuration :
#storagebackend: ldapstorage
#storageserver: ldap://ldap.librelogiciel.com:389
#storagename: dc=librelogiciel,dc=com
#storageuser: cn=notadmin,dc=librelogiciel,dc=com
#storageuserpw: abc.123
#
# Here we define some helpers to know where 
# to plug into an existing LDAP directory
#userbase: ou=People,dc=librelogiciel,dc=com
#userrdn: uid
#balancebase: ou=People,dc=librelogiciel,dc=com
#balancerdn: uid
#groupbase: ou=Groups,dc=librelogiciel,dc=com

#
# How to create new accounts and groups
# authorized values are "below" and "attach(objectclass name)"
#
# "below" creates the new accounts/groups as standalone entries
# below the above defined 'userbase' ou
# 
# attach(objectclass name) tries to find some existing user/group
# using the above defined 'userrdn' or 'grouprdn' and 'userbase'
# 'groupbase', and attach the PyKota specific entries to it.
#
# a possible value:  newuser: attach(posixAccount)
#newuser : below
#newgroup : below
#
# LDAP attribute which stores the user's email address
#usermail : mail

# 
# Choose what attribute contains the list of group members
# common values are : memberUid, uniqueMember, member
#groupmembers: memberUid

# Activate low-level LDAP cache yes/no
# Nothing to do with "storagecaching" which is higher level
# and database independant.
# This saves some search queries and may help with heavily
# loaded LDAP servers.
# This is EXPERIMENTAL.
#
# BEWARE : SETTING THIS TO 'YES' CAUSES PROBLEMS FOR NOW
# BETTER TO LET IT SET TO 'NO'
ldapcache: no

# Where to log ?
# supported values : stderr, system (system means syslog, but don't use 'syslog' here)
# if the value is not set then the default SYSTEM applies.
logger: system

# Enable debugging ? Put YES or NO there.
# From now on, YES is the default in this sample
# configuration file, so that debugging is activated
# when configuring PyKota. After all works, just
# put NO instead to save some disk space in your
# logs.
# Actually only database queries are logged.
debug : Yes

# Mail server to use to warn users
# If the value is not set then localhost is used.
smtpserver: localhost

# Email domain
# If the value is not set, and the mail attribute for the user
# is not set in the PyKota storage, be it LDAP (see usermail directive
# above) or PostgreSQL, then email messages are sent to 
# username@smtpserver
#
# If the value is set, then email messages are sent to
# username@maildomain using the SMTP server defined above
#
# Set the appropriate value below, example.com set as per RFC2606.
maildomain: example.com

# Should we force usernames to be all lowercase when printing ?
# Default is No. 
# This is a global option only.
# Some people reported that WinXP sends mixed case usernames
# setting 'utolower: Yes' solves the problem.
# Of course you have to user lowercase only when adding
# users with edpykota, because ALL database accesses are
# still case sensitive.
#
# If utolower is Yes, the usernames received from the printing
# system is converted to lowercase at the start of the cupspykota
# backend or of the pykota filter.
#
# If utolower is No, which is the default, strict case checking
# is done, this means that users 'Jerome' and 'jerome' are
# different. Printer and groups names are ALWAYS case sensitive.
utolower: No

# What is the accounting backend to use
# 
# supported values :
#
#    - querying : asks the printer for its lifetime page counter
#                 via either SNMP, AppleTalk, or any external
#                 command. This method is the method used by
#                 default in PyKota since its beginning.
#
#    - external : delegates the job's size computation to any 
#                 external command of your choice. A stupid and 
#                 completely unreliable example, but which
#                 shows what this command may be is :
#
#                   accounter: external(/bin/grep -c showpage)
#
#                 Another one, which should work with all DSC
#                 compliant Postscript files :
#
#                   accounter: external(/bin/grep -c "%%Page:")
# 
#    - stupid : counts the occurences of the 'showpage' postscript
#               statement in the document to be printed.
#               THIS IS NOT RELIABLE. This is just to serve as
#               an example on how to implement your own accounting
#               method.
#
# This value can be set either globally or on a per printer basis
# If both are defined, the printer option has priority.
# if not set it defaults to 'querying'.
#
# A script which seems to be accurate, copy it from the
# untested/postscript directory to another place.
# accounter: external(/usr/share/pykota/pagecount.sh)
# WARNING : it may not work when multiple copies are asked.
#           this breaks ghostscript, I don't know why yet.
#
# default value 
accounter: querying

# Print Quota administrator
# These values can be set either globally or per printer or both.
# If both are defined, the printer option has priority.
# If these values are not set, the default admin root 
# and the default adminmail root@localhost are used.
admin: John Doe
adminmail: root@localhost

#
# Who should we send an email to in case a quota is reached ?
# possible values are : DevNull, User, Admin, Both, External(some command)
# The Both value means that the User and the Admin will receive 
# an email message.
# The DevNull value means no email message will be sent.
# This value can be set either globally or per printer or both.
# If both are defined, the printer option has priority.
# If the value is not set, then the default BOTH applies.
#
#   Format of the external syntax :
#
#       mailto: external(/usr/bin/mycommand >/dev/null)
#
#   You can use :
#
#       '%(action)s'            will contain either WARN or DENY
#       '%(username)s'          will contain the user's name
#       '%(printername)s'       will contain the printer's name
#       '%(email)s'             will contain the user's email address
#       '%(message)s'           will contain the message if you want 
#                               to use it.
#
#   On your command line, to pass arguments to your command.
#   Example :
#
#       mailto: external(/usr/bin/callpager %(username)s "Quota problem on %(printername)s" >/dev/null)
#
#   To automatically send a WinPopup message (this may only work with a PDC, 
#   here the same machine does Samba as PDC + CUPS) :
#
#       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)
#
#   NB : I use ISO-8859-15, but Windows expects UTF-8, so we pipe the message
#        into iconv before sending it to the Windows user.
#
# or more simply :
#
#       mailto: external(/usr/share/pykota/mailandpopup.sh %(username)s %(printername)s "%(email)s" "%(message)s" 2>&1 >/dev/null)
#
#   NB : The mailandpopup.sh shell script is now included in PyKota
#
#   NB : in ANY case, don't forget to redirect your command's standard output
#        somewhere (e.g. >/dev/null) so that there's no perturbation to the 
#        underlying layer (filter or backend)
#
mailto: both

#
# Grace delay in days
# This value can be set either globally or per printer or both.
# If both are defined, the printer option has priority.
# If the value is not set then the default seven (7) days applies.
gracedelay: 7

#
# Poor man's threshold
# If account balance reaches below this amount,
# a warning message is sent by email
#
# If unset, default poor man's threshold is 1.0.
# This option can only appear in the global section
poorman: 2.0

# Poor man's warning message
# The warning message that is sent if the "poorman" value is reached
# Again this must appear in the global section
poorwarn: Your Print Quota account balance is low. 
 Soon you'll not be allowed to print anymore.

# Soft limit reached warning message
# The warning message that is sent if the soft quota limit is reached
# May appear either globally or on a per-printer basis
softwarn: Your Print Quota Soft Limit is reached.
 This means that you may still be allowed to print for some
 time, but you must contact your administrator to purchase 
 more print quota.
 
# Hard limit reached error message
# The error message that is sent if the hard quota limit is reached
# May appear either globally or on a per-printer basis
hardwarn: Your Print Quota Hard Limit is reached.
 This means that you are not allowed to print anymore.
 Please contact your administrator at root@localhost
 as soon as possible to solve the problem.

# one section per printer, or no other section at all if all options 
# are defined globally.
# Each section's name must be the same as the printer's queue name as defined
# in your printing system, be it CUPS or LPRng.
# If you don't want any special printer section, just comment out
# the line below so that following options are global.
[hpmarketing]

# How to query the hpmarketing printer for its page counter.
# THIS IS ONLY USED IF YOU HAVE SET 'accounter' TO 'querying'
# JUST COMMENT IT OUT IF YOU USE ANY OTHER ACCOUNTING METHOD.
# (it would be ignored anyway)
#
# In the lines below "%(printer)s" is automatically replaced
# at run time with your printer's Fully Qualified Domain Name
# e.g. myprinter.example.com
#
# Only snmp(community, oid) and external(command) are supported
#
# Example : 
#     requester: external(/usr/bin/snmpget -v1 -c public -Ov %(printer)s mib-2.43.10.2.1.4.1.1 | cut -f 2,2 -d " ")
# and :
#     requester: snmp(public, mib-2.43.10.2.1.4.1.1)
# are equivalent
#
#################################################
# NB : the 'snmp()' requester is now deprecated #
# because it has some accuracy problems.        #
# please use 'external()' instead.              #
#################################################
#
# Another untested example, using npadmin :
#     requester: external(/usr/bin/npadmin --pagecount %(printer)s)
#
# Another example, for AppleTalk printers which works fine :
# (You may need the pap CUPS backend installed, and copy the 
# pagecount.ps file from untested/netatalk into /etc or any 
# appropriate location)
#     requester: external(/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)
#
# An example for parallel printers like the HP Laserjet 5MP :
#
#     requester: external(/bin/cat /usr/share/pykota/pagecount.pjl >/dev/lp0 && /usr/bin/head -2 </dev/lp0 | /usr/bin/tail -1)
# 
# 
# This value can be set either globally or per printer or both.
# If both are defined, the printer option has priority.
#
# NB : The SNMP oid mib-2.43.10.2.1.4.1.1 works on HP Laserjet Printers, but it may
#      be different with other brands, refer to your printer's documentation 
#      for details. Also you may have to specify -v2c or -v3 depending on your 
#      printer's support for different versions of the SNMP specification.
#
#
# Some examples and comments provided by Bob Martel from csuohio.edu
#
# For several printers I could not get the page count using snmpget.  I
# resorted to snmpwalk:
# 
# requester: external(/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)
#
# The last example is still more ugly, some of the printers only provided
# their counters without names, but at least always on the same line:
#
# requester: external(/opt/local/net-snmp/bin/snmpwalk -v 1 -Cc -c public -Ov %(printer)s | grep Counter32 | tail -2 | head -1 | cut -d " " -f2)
#
#
# An example using netcat and a preformatted PJL job which you can find
# in the untested/pjl directory, which is sent to a JetDirect print
# server on port 9100 :
#
# requester: external(/bin/nc -w 2 %(printer)s 9100 </usr/share/pykota/pagecount.pjl | /usr/bin/tail -2)
#
#
# An example using the contributed pagecount.pl script which does 
# the same as above, but should work on more printers : 
#
# requester: external(/usr/share/pykota/pagecount.pl %(printer)s 9100)
#
#
# WARNING : In any case, when using an external requester, please test the command line outside
#           of PyKota before. This will save you some headaches in case it doesn't work as expected.
#
# The waitprinter.sh is there to wait until the printer is idle again.
# This should prevent a job to be sent to the printer while another one is 
# not yet finished (not all pages are printed, but the complete job is in 
# the printer)
requester: external(/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 " ")

# Default policy for inexistant users (e.g. root)
# either allow or deny or external(some command here)
# This value can be set either globally or per printer or both.
# If both are defined, the printer option has priority.
# If the value is not set then the default policy DENY applies.
# ATTENTION :
#     Before 1.04 the default value was ALLOW, but unknown users
#     allowed to print causes accuracy problems : their jobs are
#     charged to the next person who prints on the same printer.
# There's no policy wrt inexistant groups, they are ignored.
#
# external policy can be used to launch any external command of your choice,
# for example to automatically add the user to the quota storage 
# if he is unknown. Example :
# 
#       policy: external(/usr/bin/edpykota --add --printer %(printername)s --softlimit 50 --hardlimit 60 %(username)s >/dev/null) 
#
# Of course you can launch any command of your choice with this, e.g. :
#
#       policy: external(/usr/local/bin/myadminscript.sh %(username)s >/dev/null)

# You can use :
#
#       '%(username)s'          will contain the user's name
#       '%(printername)s'       will contain the printer's name
#
#   On your command line, to pass arguments to your command.
#
#   NB : Don't forget to redirect your command's standard output somewhere 
#        (e.g. >/dev/null) so that there's no perturbation to the underlying
#        layer (filter or backend)
#
# If the user still doesn't exist after external policy command was 
# launched (the external command didn't add it), or if an error occured
# during the execution of the external policy command, the job is rejected.
#
policy: deny

# Pre and Post Hooks 
# These directives allow the easy plug-in of any command of your choice
# at different phases of PyKota's execution.
# Pre and Post Hooks can access some of PyKota's internal information
# by reading environment variables as described below.
# The actual phase of PyKota's execution is available in the
# PYKOTAPHASE environment variable.
# Pre and Post Hooks can be defined either globally, per printer,
# or both if both are defined, the printer specific hook has
# priority.
#
# List of available environment variables :
# NB : Most of these variables are also available during the execution
# of external commands defined in the accounter, requester or mailto 
# directives.
#
# PYKOTAPHASE : BEFORE or AFTER the job is sent to the printer
# PYKOTACTION : ALLOW or DENY or WARN for current print job
# PYKOTAUSERNAME : user's name
# PYKOTAPRINTERNAME : printer's name
# PYKOTAJOBID : job's id
# PYKOTATITLE : job's title
# PYKOTAFILENAME : job's filename
# PYKOTACOPIES : number of copies
# PYKOTAOPTIONS : job's options
# PYKOTABALANCE : user's account balance
# PYKOTALIFETIMEPAID : user's grand total paid 
# PYKOTAPAGECOUNTER : user's page counter on this printer
# PYKOTALIFEPAGECOUNTER : user's life time page counter on this printer
# PYKOTASOFTLIMIT : user's soft page limit on this printer
# PYKOTAHARDLIMIT : user's hard page limit on this printer
# PYKOTADATELIMIT : user's soft to hard limit date limit on this printer

# PreHook : gets executed after being sure the user, printer and user quota
# entry on the printer both exist in the PyKota database, and after
# checking if the user is allowed to print or not, but just before
# the job is sent to the printer (if allowed)
# prehook has access to many environment variables :
#
# PYKOTAACTION contains either "ALLOW", "WARN" or "DENY" and 
# represents the action which is to be done wrt the print job.
# PYKOTAPHASE contains 'BEFORE' during execution of prehook 
#
# uncomment the line below to see what environment variables are available
# prehook: /usr/bin/printenv >/tmp/before

# PostHook : gets executed after the job has been added to the history.
# posthook has access to all the environment variables defined above,
# as well as two additionnal environment variables : PYKOTAJOBPRICE 
# and PYKOTAJOBSIZE. 
# PYKOTAPHASE contains 'AFTER' during execution of posthook.
#
# uncomment the line below to see what environment variables are available
#posthook: /usr/bin/printenv >/tmp/after
