[2048] | 212 | as an purchaseable add-on. |
---|
[2049] | 213 | |
---|
| 214 | - Third party web based management tools are available. |
---|
[1154] | 215 | |
---|
| 216 | ==================================================================== |
---|
| 217 | |
---|
[739] | 218 | Planned features are described in the TODO file. |
---|
| 219 | |
---|
[1507] | 220 | Actually two (or an infinity of) page accounting methods are |
---|
[980] | 221 | implemented : |
---|
[695] | 222 | |
---|
[1475] | 223 | - The 'hardware' method consists in querying the printer (via SNMP |
---|
[1181] | 224 | or Netatalk or any other method of your choice) for its total pages |
---|
[1186] | 225 | counter. |
---|
[980] | 226 | |
---|
[1600] | 227 | This is done both at the beginning and at the end of a |
---|
[1186] | 228 | print job. The counters difference is then immediately used to |
---|
| 229 | decrease the user's account balance or increase his quota usage. |
---|
| 230 | |
---|
[1475] | 231 | - The 'software' method consists in delegating the computation of the |
---|
[980] | 232 | job's size in number of pages to any external command of your choice. |
---|
| 233 | The command can read the job's data from its standard input and MUST |
---|
[1186] | 234 | output the job's size on its standard output. Changes to the user |
---|
[1600] | 235 | account are reported immediately. |
---|
[980] | 236 | |
---|
[1600] | 237 | PyKota is known to work fine with most laser printers, either with |
---|
| 238 | software accounting, or with hardware accounting if the printer |
---|
| 239 | supports this. |
---|
[724] | 240 | |
---|
[695] | 241 | ============================================================ |
---|
| 242 | |
---|
[2001] | 243 | SUPPORT CONTRACTS: |
---|

---|
[2126] | 256 | interested in purchasing such a contract. |
---|
[2001] | 257 | |
---|
[2126] | 258 | Remember that purchasing a support contract for Free Software like PyKota |
---|
| 259 | is a great way to show your appreciation for the work already being done |
---|
| 260 | on this project, and will help to improve this software in the future. |
---|
| 261 | |
---|
[2001] | 262 | ============================================================ |
---|
| 263 | |
---|
[695] | 264 | INSTALLATION: |
---|
| 265 | ============= |
---|
| 266 | |
---|
[1186] | 267 | NB : |
---|
| 268 | ==== |
---|
[887] | 269 | |
---|
[1397] | 270 | You may learn more about PyKota, if it fits your own organization, |
---|
| 271 | its internal working, and some potential performance drawbacks and |
---|
[2054] | 272 | how to avoid them, in a document created by Ryan Suarez at : |
---|
[1397] | 273 | |
---|
[2005] | 274 | http://archive.macosxlabs.org/forum/webcrossing_archive/documentation/Pykota_and_CUPS/Pykota_and_CUPS.html |
---|
[1034] | 275 | |
---|
[1651] | 276 | You may also find the following document interesting : |
---|
| 277 | |
---|
| 278 | http://es.tldp.org/Tutoriales/doc-openldap-samba-cups-python/ |
---|
| 279 | |
---|
| 280 | This document, written in Spanish by Sergio Gonzalez Gonzalez, |
---|
| 281 | describes the integration of PyKota into an OpenLDAP + Samba |
---|
| 282 | + CUPS installation. Even for people who can't read spanish |
---|
| 283 | this document is really interesting, and contains lots of |
---|
| 284 | screenshots. |
---|
| 285 | |
---|
[1951] | 286 | Finally, SuSe users may find the following document to best describe |
---|
| 287 | how to install PyKota on their favorite distribution. It's a Spanish |
---|
| 288 | document written by Dennis Romero : |

---|
| 291 | |
---|
| 292 | |
---|
[714] | 293 | Prerequisite : |
---|
| 294 | -------------- |
---|
| 295 | |
---|
| 296 | You need to have the following tools installed on the CUPS Server : |
---|
| 297 | |
---|
[1886] | 298 | - CUPS (http://www.cups.org) or LPRng (http://www.lprng.com) |
---|
| 299 | - Python v2.1 or above (http://www.python.org) |
---|
| 300 | - eGenix' mxDateTime Python extension (http://www.egenix.com) |
---|
[1771] | 301 | - The JAXML Python module to be able to dump datas in the XML format. |
---|
[1886] | 302 | (http://www.librelogiciel.com/software/) |
---|
[1771] | 303 | - The Python-SNMP module to query printers for their page counter. |
---|
[1965] | 304 | (http://pysnmp.sourceforge.net). |
---|
| 305 | IMPORTANT : version 3.4.3 (or 3.4.2) is REQUIRED. Versions 2.x or |
---|
| 306 | 4.x won't work for now. |
---|
[1771] | 307 | - The Python-OSD module to use the graphical print quota reminder. |
---|
| 308 | - SNMP tools (specifically the snmpget command) if you prefer to |
---|
| 309 | use your own script to request query printers. |
---|
[919] | 310 | - Netatalk (specifically the pap command) if you plan to |
---|
| 311 | request your printer's lifetime page counter via AppleTalk. |
---|
[1886] | 312 | (http://netatalk.sourceforge.net) |
---|
[1927] | 313 | - The ReportLab Python module (http://www.reportlab.org) if you want |
---|
| 314 | to have PyKota generate nice banners for you. |
---|
| 315 | - The Python Imaging Library (aka PIL) module |
---|
| 316 | (http://www.pythonware.com/downloads) if you want to have PyKota |
---|
| 317 | generate nice banners for you. |
---|
[1043] | 318 | - PostgreSQL's PygreSQL Python extension and the PostgreSQL client |
---|
| 319 | libraries if you plan to use PostgreSQL as the Quota Storage |
---|
| 320 | backend. |
---|
[1886] | 321 | (http://www.postgresql.org and http://www.pygreql.org) |
---|
[1043] | 322 | or |
---|
| 323 | - python-ldap Python module and the OpenLDAP client libraries |
---|
[1823] | 324 | if you plan to use an LDAP server as the Quota Storage backend. |
---|
[1886] | 325 | (http://www.openldap.org and http://python-ldap.sourceforge.net) |
---|
[714] | 326 | |
---|
[1771] | 327 | On Intel i386 architecture, and for performance reasons, it is |
---|
| 328 | strongly suggested that you install the Python accelerator Psyco, |
---|
| 329 | available at : |
---|
[1570] | 330 | |
---|
| 331 | http://psyco.sourceforge.net |
---|
| 332 | |
---|
[1571] | 333 | Under Debian : |
---|
| 334 | |
---|
| 335 | $ apt-get install python-psyco |
---|
| 336 | |
---|
| 337 | Other architectures may be supported as well in the future, check |
---|
[1600] | 338 | this on Psyco's website. |
---|
[1571] | 339 | |
---|
[1578] | 340 | Installing Psyco is not mandatory, but it will speedup PCL5 parsing |
---|
[1570] | 341 | by almost 3 times. PostScript and PDF parsing can also benefit, |
---|
| 342 | but in an almost unnoticeable manner since this part of the code |
---|
[1575] | 343 | is already optimal. For PCL5 this is a completely different matter, |
---|
[1570] | 344 | and if you install Psyco you will never regret it ! |
---|
[1600] | 345 | Same remark applies for PCL6 (aka PCLXL) : the parser is completely |
---|
| 346 | different, but the performance gain with Psyco is impressive. |
---|
[1570] | 347 | |
---|
[1186] | 348 | You may also benefit from having the following tools installed to |
---|
| 349 | deal with some printers : |
---|
| 350 | |
---|
| 351 | - npadmin |
---|
| 352 | - netcat |
---|
| 353 | - ghostscript |
---|
| 354 | |
---|
[714] | 355 | You need to have the following tools installed on the Quota Storage |
---|
| 356 | Server : |
---|
| 357 | |
---|
[1886] | 358 | - PostgreSQL (http://www.postgresql.org) |
---|
[714] | 359 | |
---|
[1043] | 360 | or |
---|
| 361 | |
---|
[1886] | 362 | - OpenLDAP, or any other LDAP server (http://www.openldap.org) |
---|
[1043] | 363 | |
---|
[1086] | 364 | NB : |
---|
| 365 | |
---|
| 366 | PygreSQL must be linked with the PostgreSQL client libraries on |
---|
| 367 | the Print Server. The PostgreSQL client libraries' version must |
---|
| 368 | match the PostgreSQL version used on the Quota Storage Server. |
---|
[714] | 369 | |
---|
[1043] | 370 | or |
---|
| 371 | |
---|
[1086] | 372 | python-ldap must be linked with the OpenLDAP client libraries on the |
---|
[1823] | 373 | Print Server. The OpenLDAP client libraries' version should match the |
---|
| 374 | OpenLDAP version used on the Quota Storage Server, if applicable. |
---|
[1043] | 375 | |
---|
[714] | 376 | This list of prerequisite software may change in the future, when |
---|
| 377 | PyKota will support more functionnalities you will be given |
---|
| 378 | alternatives. |
---|
| 379 | |
---|
[952] | 380 | Of course the Print Server and the Quota Storage Server can be the |
---|
[851] | 381 | very same machine if you've got a tiny network, or you can have |
---|
[952] | 382 | multiple Print Servers all storing their quotas on the same Quota |
---|
[851] | 383 | Storage Server if you've got a bigger network. |
---|
| 384 | |
---|
[1886] | 385 | Hint : |
---|
| 386 | ------ |
---|
| 387 | |
---|
| 388 | - The Debian GNU/Linux distribution is to our knowledge the |
---|
| 389 | easiest distribution to install PyKota on, because all |
---|
| 390 | of PyKota dependencies are already included, excepted |
---|
| 391 | for the PySNMP (http://pysnmp.sourceforge.net) module |
---|
| 392 | which for now has to be downloaded separately. |
---|
| 393 | |
---|
[714] | 394 | Then : |
---|
| 395 | ------ |
---|
| 396 | |
---|
[2135] | 397 | Download the latest PyKota version from the Subversion tree : |
---|
[695] | 398 | |
---|
[2135] | 399 | $ svn co svn://svn.librelogiciel.com/pykota/trunk pykota |
---|
[695] | 400 | |
---|
[1906] | 401 | You can now check if the dependencies are correct by typing : |
---|
[695] | 402 | |
---|
[2135] | 403 | $ python checkdeps.py |
---|
[1906] | 404 | |
---|
| 405 | To install the software, just type : |
---|
| 406 | |
---|
[2135] | 407 | $ python setup.py install |
---|
[695] | 408 | |
---|
| 409 | You may need to be logged in with sufficient privileges (e.g. root) |
---|
| 410 | |
---|
[1960] | 411 | Create a system user for PyKota : |
---|
| 412 | |
---|
[2135] | 413 | $ adduser --system --group --home /etc/pykota --gecos PyKota pykota |
---|
[1960] | 414 | |
---|
| 415 | Put the user your printing system is run as in the pykota system group : |
---|
| 416 | |
---|
[2135] | 417 | $ adduser lp pykota |
---|
[1960] | 418 | |
---|
| 419 | NB : on our system, the CUPS printing system runs as system user 'lp'. |
---|
| 420 | Please adapt this to your own system. |
---|
| 421 | |
---|
[695] | 422 | Go to the initscripts subdirectory of PyKota's sources, and choose |
---|
[1600] | 423 | the appropriate storage backend for your configuration. Read carefully |
---|
[695] | 424 | the associated README file and execute the initialization script |
---|
[878] | 425 | to create an empty PyKota Storage. Upgrade scripts may be |
---|
| 426 | provided as well. |
---|
[695] | 427 | |
---|
[1186] | 428 | Copy the conf/pykota.conf.sample and conf/pykotadmin.conf.sample |
---|
[1107] | 429 | sample configuration files to /etc/pykota/pykota.conf and |
---|
[1905] | 430 | /etc/pykota/pykotadmin.conf |
---|
| 431 | The installation script usually copies these files into /usr/share/pykota |
---|
[1198] | 432 | |
---|
[1979] | 433 | NB : You can move PyKota's configuration files elsewhere, they will |
---|
| 434 | be searched first in user pykota's home directory. |
---|
| 435 | |
---|
[1905] | 436 | You need to adapt these files to your own needs. Especially you may |
---|
| 437 | have to create sections named after your own printers, and change |
---|
| 438 | the administrator's email address which by default is |
---|
| 439 | root@localhost. Read and try to understand these two very well |
---|
| 440 | commented files, so that you'll encounter less problems later. |
---|
| 441 | |
---|
[1198] | 442 | Also be sure to double check that commands that query printers |
---|
[1186] | 443 | for their internal page counter work from the command line |
---|
| 444 | before using them in PyKota's configuration. |
---|
[695] | 445 | |
---|
[1186] | 446 | The rest of the installation depends on your printing system : |
---|
| 447 | |
---|
[1185] | 448 | - CUPS Printing System : |
---|
[952] | 449 | |
---|
[1185] | 450 | Once and for all : |
---|
[952] | 451 | |
---|
[1185] | 452 | Create a symbolic link to the cupspykota backend |
---|
| 453 | in CUPS's backend directory : |
---|
| 454 | |
---|
| 455 | $ cd /usr/lib/cups/backend |
---|
[1345] | 456 | $ ln -s /usr/share/pykota/cupspykota cupspykota |
---|
[1185] | 457 | |
---|
| 458 | Restart CUPS so that the new backend can be detected. |
---|
| 459 | |
---|
| 460 | $ /etc/init.d/cupsys restart |
---|
| 461 | |
---|
[1600] | 462 | or : |
---|
| 463 | |
---|
[1979] | 464 | $ /etc/rc.d/init.d/cupsys restart |
---|
[1600] | 465 | |
---|
| 466 | or any similar command depending on your operating system. |
---|
| 467 | |
---|
[1185] | 468 | For new printers : |
---|
[952] | 469 | |
---|
[1185] | 470 | Go to CUPS management interface (http://localhost:631) |
---|
| 471 | and choose the appropriate PyKota managed device depending |
---|
| 472 | on the type of printer you use. For example, if your |
---|
| 473 | printer is waiting on : |
---|
| 474 | |
---|
[1354] | 475 | socket://myprinter.example.com:9100 |
---|
[1185] | 476 | |
---|
| 477 | Then choose : |
---|
| 478 | |
---|
[1354] | 479 | cupspykota:socket://myprinter.example.com:9100 |
---|
[1185] | 480 | |
---|
| 481 | Configure your printer as usual. |
---|
| 482 | |
---|
[1186] | 483 | Now double check /etc/pykota/pykota.conf |
---|
[1600] | 484 | |
---|
| 485 | You should manually create a section named after the |
---|
[1402] | 486 | printer you've just added, unless you have set |
---|
| 487 | all options globally. |
---|
[1600] | 488 | |
---|
[1408] | 489 | The new pkhint command can help you with correct settings |
---|
| 490 | for your printers, but don't rely on it because it is still |
---|
[1600] | 491 | experimental work. To use pkhint, you have to feed it with |
---|
| 492 | CUPS' printers.conf file this way : |
---|
[1186] | 493 | |
---|
[1600] | 494 | $ pkhint </etc/cups/printers.conf |
---|
| 495 | |
---|
| 496 | pkhint will try to tell you what is the best accounting |
---|
| 497 | method for each printer and will print some lines you'll |
---|
| 498 | just have to copy&paste in the appropriate sections in |
---|
| 499 | /etc/pykota/pykota.conf |
---|
| 500 | |
---|
[1185] | 501 | That's all. |
---|
[952] | 502 | |
---|
[1185] | 503 | For existing printers : |
---|
| 504 | |
---|
[1186] | 505 | If you had already installed a version of PyKota earlier |
---|
| 506 | than 1.16alpha7, then remove the *cupsFilter lines in your |
---|
[1979] | 507 | PPD files for each already managed printer. Each |
---|
[1186] | 508 | line to remove is of the form : |
---|
[1185] | 509 | |
---|
[1345] | 510 | *cupsFilter: "application/vnd.cups-postscript 0 /usr/share/pykota/pykota" |
---|
[1185] | 511 | |
---|
[1345] | 512 | This means that each time the pstops filter will be executed, it will |
---|
| 513 | pass the job's data through the pykota filter which is present in |
---|
| 514 | /usr/share/pykota |
---|
| 515 | |
---|
[1185] | 516 | Don't touch anything else, especially any other *cupsFilter line. |
---|
[1186] | 517 | Then save each of these files. |
---|
[1185] | 518 | |
---|
| 519 | Then, the easiest is to directly modify the DeviceURI lines |
---|
| 520 | in /etc/cups/printers.conf, you just have to put |
---|
| 521 | 'cupspykota:' in front of what is already on these lines. |
---|
| 522 | For example, replace : |
---|
| 523 | |
---|
[1354] | 524 | DeviceURI socket://myprinter.example.com:9100 |
---|
[1185] | 525 | |
---|
| 526 | with : |
---|
| 527 | |
---|
[1354] | 528 | DeviceURI cupspykota:socket://myprinter.example.com:9100 |
---|
[1345] | 529 | |
---|
| 530 | or : |
---|
[1185] | 531 | |
---|
[1354] | 532 | DeviceURI cupspykota://socket://myprinter.example.com:9100 |
---|
[1345] | 533 | |
---|
[1185] | 534 | Save the file and restart CUPS. |
---|
[1600] | 535 | |
---|
| 536 | Here too, you may find it interesting to use the pkhint command as |
---|
| 537 | described above to help with manual configuration of the file |
---|
| 538 | /etc/pykota/pykota.conf |
---|
[695] | 539 | |
---|
[1185] | 540 | - LPRng Printing System : |
---|
[952] | 541 | |
---|
[1600] | 542 | For each printer on which you want to use PyKota : |
---|
| 543 | |
---|
| 544 | Modify the printer's entry in /etc/printcap : you have to add |
---|
| 545 | the three following lines : |
---|
| 546 | |
---|
[1612] | 547 | :achk=true:\ |
---|
[1600] | 548 | :as=/usr/share/pykota/lprngpykota:\ |
---|
| 549 | :ae=/usr/share/pykota/lprngpykota:\ |
---|
| 550 | |
---|
| 551 | This will tell LPRng to activate accounting, and use the lprngpykota |
---|
| 552 | accounting filter both at the start and at the end of printing. |
---|
| 553 | |
---|
| 554 | When all modifications are done, just save the /etc/printcap file and |
---|
| 555 | restart LPRng : |
---|
| 556 | |
---|
| 557 | $ /etc/init.d/lprng restart |
---|
| 558 | |
---|
| 559 | or : |
---|
[1500] | 560 | |
---|
[1600] | 561 | $ /etc/rc.d/init.d/lprng restart |
---|
| 562 | |
---|
| 563 | or any similar command depending on your operating system. |
---|
| 564 | |
---|
| 565 | NB : the pkhint command can't be used with LPRng for now, so you |
---|
| 566 | have to modify /etc/pykota/pykota.conf carefully. The comments |
---|
| 567 | in this file will help you. |
---|
| 568 | |
---|
[1186] | 569 | Now you can begin to populate the PyKota's database with printers, |
---|
| 570 | users and groups : |
---|
[952] | 571 | |
---|
[716] | 572 | Add printers and users to the quota system and set their quota values : |
---|
[695] | 573 | |
---|
[1345] | 574 | Starting from version 1.18alpha2, the preferred command to manage |
---|
| 575 | printers is named pkprinters |
---|
| 576 | |
---|
| 577 | $ pkprinters --help |
---|
| 578 | |
---|
| 579 | will tell you how to create, manage or delete printers and |
---|
| 580 | printers groups. |
---|
[1402] | 581 | |
---|
| 582 | $ pkprinters --add --charge 0.05 hp2100 |
---|
| 583 | |
---|
| 584 | would add the printer named hp2100 with a price per page |
---|
| 585 | of 0.05 unit. |
---|
[1345] | 586 | |
---|
[1402] | 587 | Now set quotas for users on this printer : |
---|
| 588 | |
---|
[1086] | 589 | $ edpykota --add -P hp2100 -S 40 -H 50 user1 ... userN |
---|
[724] | 590 | |
---|
[725] | 591 | launching edpykota without any argument or with the --help |
---|
| 592 | command line option will show you all the possibilities. |
---|
[1086] | 593 | |
---|
| 594 | by default, each user is limited by "quota", this means that on |
---|
| 595 | each printer he can have a different soft and hard limit. |
---|
| 596 | You may want to limit the user by his account balance value, |
---|
[1107] | 597 | in which case, the print quota is shared between all printers |
---|
[1086] | 598 | instead of being different. To do this, use the following : |
---|
| 599 | |
---|
| 600 | $ edpykota --add -P hp2100 --limitby balance --balance 10 user1 ... userN |
---|
| 601 | |
---|
| 602 | This will put 10 $ (or Euros, PyKota doesn't care) on each user's account |
---|
| 603 | balance, and tell PyKota to limit them by their account balance value. |
---|
| 604 | Whenever they print on any printer, their account balance value is |
---|
| 605 | decreased by an amount which depends on the particular price per page |
---|
| 606 | and per job that you may have defined on the printer with edpykota's |
---|
| 607 | --charge command line option. |
---|
[1107] | 608 | Soft and Hard limits are not used if "--limitby balance" is used, |
---|
| 609 | but you can define a "poorman"'s threshold in /etc/pykota/pykota.conf |
---|
| 610 | to obtain a similar result (warning message when quota is low). |
---|
[695] | 611 | |
---|
[990] | 612 | Restart CUPS or LPRng, for example under Debian GNU/Linux systems : |
---|
[695] | 613 | |
---|
[725] | 614 | $ /etc/init.d/cupsys restart |
---|
[990] | 615 | |
---|
| 616 | or : |
---|
| 617 | |
---|
| 618 | $ /etc/init.d/lprng restart |
---|
[695] | 619 | |
---|
| 620 | Your users now should be able to print but not exceed their |
---|
| 621 | printing quota. |
---|
| 622 | |
---|
[1149] | 623 | To see printer quota usage, you can use : |
---|
[794] | 624 | |
---|
| 625 | $ repykota --printer lp |
---|
| 626 | |
---|
| 627 | or : |
---|
| 628 | |
---|
| 629 | $ repykota |
---|
| 630 | |
---|
| 631 | which will print quota usage for all users on all printers, |
---|
[2054] | 632 | along with totals, if you are a PyKota Administator. If you are |
---|
[1107] | 633 | a regular user, only your own quota report will be produced. |
---|
[794] | 634 | |
---|
[1107] | 635 | Quota reports are also available remotely by using the CGI script |
---|
[1345] | 636 | printquota.cgi provided in the cgi-bin/ subdirectory. You can |
---|
| 637 | also use the CSS stylesheet present in the stylesheets/ subdirectory |
---|
[1402] | 638 | and put it at your web server's DocumentRoot, to benefit from a nicer |
---|
| 639 | look, especially quota violations will appear in different colors. |
---|

[1979] | 646 | Additionnal tools : |
---|
| 647 | ------------------- |
---|
| 648 | |
---|
| 649 | Some people have developped tools around PyKota, and make |
---|
| 650 | them available under the GNU General Public License : |
---|
| 651 | |
---|
| 652 | - Kanakorn Horsiritham developped phpPykotaAdmin which is |
---|
[2126] | 653 | a web based database independant administrative GUI, |
---|
| 654 | written in PHP. |
---|
[1979] | 655 | |
---|
| 656 | http://opensource.psu.ac.th/~kanakorn/mambo/ |
---|
[2126] | 657 | |
---|
| 658 | He was also kind enough to write an installation guide |
---|
| 659 | in english for CUPS and PyKota with phpPykotaAdmin on Fedora |
---|
| 660 | Core 3. You'll find this document on the same website. |
---|
| 661 | |
---|
| 662 | This great software currently at version 0.3 is a wonderful |
---|
| 663 | basis for an administrative GUI since it only depends on |
---|
| 664 | PyKota commands to be present to successfully manage |
---|
| 665 | PyKota's database. |
---|
[1979] | 666 | |
