---|
| 3327 | =head1 DESCRIPTION |
---|
| 3328 | |
---|
| 3329 | Klask is a small tool to find where is connected a host in a big network |
---|
| 3330 | and on which VLAN. |
---|
| 3331 | Klask mean search in brittany. |
---|
| 3332 | No hight level protocol like CDL, LLDP are use. |
---|
| 3333 | Everything is just done with SNMP request on MAC address. |
---|
| 3334 | |
---|
| 3335 | Limitation : loop cannot be detected and could be problematic when the map is created (C<updatesw> method). |
---|
| 3336 | If you use PVST or MSTP and create loop between VLAN, |
---|
| 3337 | you have to use C<portignore> functionality on switch port to cut manually loop |
---|
| 3338 | (see config file below). |
---|
| 3339 | |
---|
| 3340 | When you use a management port to administrate a switch, |
---|
| 3341 | it's not possible to create the map with this switch because it does not have a MAC address, |
---|
| 3342 | so other switch cannot find the real downlink port... |
---|
| 3343 | One way to work around this problem is, if you have a computer directly connected on the switch, |
---|
| 3344 | to put this IP as the fake ip for the switch. |
---|
| 3345 | The MAC address associated will be use just for the map detection. |
---|
| 3346 | The C<fake-ip> parameter is defined in the config file. |
---|
| 3347 | |
---|
| 3348 | Klask has now a web site dedicated for it: L<http://servforge.legi.grenoble-inp.fr/projects/klask>! |
---|
| 3349 | |
---|
| 3350 | |
---|
| 3351 | =head1 COMMANDS |
---|
| 3352 | |
---|
| 3353 | Some command are defined in the source code but are not documented here. |
---|
| 3354 | Theses could be not well defined, not finished, not well tested... |
---|
| 3355 | You can read the source code and use them at your own risk |
---|
| 3356 | (like for all the Klask code). |
---|
| 3357 | |
---|
| 3358 | =head2 search |
---|
| 3359 | |
---|
| 3360 | klask search computer |
---|
| 3361 | |
---|
| 3362 | This command takes one or more computer in argument. |
---|
| 3363 | It search a computer on the network and give the port and the switch on which the computer is connected. |
---|
| 3364 | |
---|
| 3365 | =head2 search-mac-on-switch |
---|
| 3366 | |
---|
| 3367 | klask search-mac-on-switch [--verbose|-v] [--vlan|-i vlan-id] switch mac_addr |
---|
| 3368 | |
---|
| 3369 | This command search a MAC address on a switch. |
---|
| 3370 | To search on all switch, you could put C<'*'> or C<all>. |
---|
| 3371 | The VLAN parameter could help. |
---|
| 3372 | |
---|
| 3373 | |
---|
| 3374 | =head2 enable |
---|
| 3375 | |
---|
| 3376 | klask enable [--verbose|-v] switch port |
---|
| 3377 | |
---|
| 3378 | This command activate a port (or an agrregate bridge port) on a switch by SNMP. |
---|
| 3379 | So you need to give the switch name and a port on the command line. |
---|
| 3380 | See L</ABBREVIATION FOR PORT>. |
---|
| 3381 | |
---|
| 3382 | Warning: You need to have the SNMP write access on the switch in order to modify it's configuration. |
---|
| 3383 | |
---|
| 3384 | |
---|
| 3385 | =head2 disable |
---|
| 3386 | |
---|
| 3387 | klask disable [--verbose|-v] switch port |
---|
| 3388 | |
---|
| 3389 | This command deactivate a port (or an agrregate bridge port) on a switch by SNMP. |
---|
| 3390 | So you need to give the switch name and a port on the command line. |
---|
| 3391 | See L</ABBREVIATION FOR PORT>. |
---|
| 3392 | |
---|
| 3393 | Warning: You need to have the SNMP write access on the switch in order to modify it's configuration. |
---|
| 3394 | |
---|
| 3395 | |
---|
| 3396 | =head2 status |
---|
| 3397 | |
---|
| 3398 | klask status [--verbose|-v] switch port |
---|
| 3399 | |
---|
| 3400 | This command return the status of a port number on a switch by SNMP. |
---|
| 3401 | The return value could be C<enable> or C<disable> word. |
---|
| 3402 | So you need to give the switch name and a port on the command line. |
---|
| 3403 | See L</ABBREVIATION FOR PORT>. |
---|
| 3404 | |
---|
| 3405 | If it's not possible to change port status with command L</enable> and L</disable> |
---|
| 3406 | (SNMP community read write access), |
---|
| 3407 | it's always possible to have the port status even for bridge agrregate port. |
---|
| 3408 | |
---|
| 3409 | |
---|
| 3410 | =head2 updatedb |
---|
| 3411 | |
---|
| 3412 | klask updatedb [--verbose|-v] [--verb-description|-d] [--chk-hostname|-h] [--chk-location|-l] [--no-rebuildsw|-R] |
---|
| 3413 | |
---|
| 3414 | This command will scan networks and update the computer database. |
---|
| 3415 | To know which are the cmputer scanned, you have to configure the file F</etc/klask/klask.conf>. |
---|
| 3416 | This file is easy to read and write because Klask use YAML format and not XML |
---|
| 3417 | (see L</CONFIGURATION>). |
---|
| 3418 | |
---|
| 3419 | Option are not stable and could be use manually when you have a new kind of switch. |
---|
| 3420 | Maybe some option will be transfered in a future C<checksw> command! |
---|
| 3421 | |
---|
| 3422 | The network parameter C<scan-mode> can have two values: C<active> or C<passive>. |
---|
| 3423 | By default, a network is C<active>. |
---|
| 3424 | This means that an C<fping> command is done at the beginning on all the IP of the network |
---|
| 3425 | and the computers that was not detected in this pass, but where their Klask entry is less than one week, |
---|
| 3426 | will have an C<arping> |
---|
| 3427 | (some OS do not respond to C<ping> but a computer have to respond to C<arping> if it want to interact with other). |
---|
| 3428 | In the scan mode C<passive>, no C<fping> and no C<arping> are done. |
---|
| 3429 | It's good for big subnet with few computer (telephone...). |
---|
| 3430 | The idea of the C<active> scan mode is to force computer to regulary send packet over the network. |
---|
| 3431 | |
---|
| 3432 | At the beginning, the command verify that the switch map checksum is always valid. |
---|
| 3433 | Otherwise, a rebuild procedure will ne done automatically. |
---|
| 3434 | |
---|
| 3435 | =head2 exportdb |
---|
| 3436 | |
---|
| 3437 | klask exportdb [--format|-f txt|html] |
---|
| 3438 | |
---|
| 3439 | This command print the content of the computer database. |
---|
| 3440 | There is actually only two format : TXT and HTML. |
---|
| 3441 | By default, format is TXT. |
---|
| 3442 | It's very easy to have more format, it's just need times... |
---|
| 3443 | |
---|
| 3444 | =head2 removedb |
---|
| 3445 | |
---|
| 3446 | klask removedb IP* computer* |
---|
| 3447 | |
---|
| 3448 | This command remove an entry in the database. |
---|
| 3449 | There is only one kind of parameter, the IP of the computers to be removed. |
---|
| 3450 | You can put as many IP as you want... |
---|
| 3451 | |
---|
| 3452 | Computer DNS names are also a valid entry because a DNS resolver is executed at the beginning. |
---|
| 3453 | |
---|
| 3454 | =head2 cleandb |
---|
| 3455 | |
---|
| 3456 | klask cleandb [--verbose|-v] --day number_of_day --repair-dns |
---|
| 3457 | |
---|
| 3458 | Remove double entry (same MAC-Address) in the computer database when the older one is older than X day (C<--day>) the new one. |
---|
| 3459 | Computer name beginning by 'float' (regex C<^float>) are not really taken into account but could be remove. |
---|
| 3460 | This could be configure with the global regex parameter C<float-regex> in the configuration file F</etc/klask/klask.conf>. |
---|
| 3461 | This functionality could be use when computer define in VLAN 1 |
---|
| 3462 | could have a float IP when they are connected on VLAN 2. |
---|
| 3463 | In the Klask database, the float DNS entries are less important. |
---|
| 3464 | |
---|
| 3465 | When reverse DNS has not been done by the past, option C<--repair-dns> force a reverse DNS check on all unkown host. |
---|
| 3466 | |
---|
| 3467 | =head2 updatesw |
---|
| 3468 | |
---|
| 3469 | klask updatesw [--verbose|-v] |
---|
| 3470 | |
---|
| 3471 | This command build a map of your manageable switch on your network. |
---|
| 3472 | The list of the switches must be given in the file F</etc/klask/klask.conf> (see L</CONFIGURATION>). |
---|
| 3473 | |
---|
| 3474 | The database has a checksum which depend of all the active switches. |
---|
| 3475 | It's use when rebuilding the database in case of change in switch configuration (one more for example). |
---|
| 3476 | |
---|
| 3477 | =head2 exportsw |
---|
| 3478 | |
---|
| 3479 | klask exportsw [--format|-f txt|dot] [--modulo|-m XX] [--shift|-s YY] |
---|
| 3480 | |
---|
| 3481 | This command print the content of the switch database. There is actually two format. |
---|
| 3482 | One is just TXT for terminal and the other is the DOT format from the graphviz environnement. |
---|
| 3483 | By default, format is TXT. |
---|
| 3484 | |
---|
| 3485 | klask exportsw --format dot > /tmp/map.dot |
---|
| 3486 | dot -Tpng /tmp/map.dot > /tmp/map.png |
---|
| 3487 | |
---|
| 3488 | In case you have too many switch connected on one switch, |
---|
| 3489 | the graphviz result graph could be too much vertical. |
---|
| 3490 | With C<--modulo> > 0, you can specify how many switches (connected on one switch) are on the same columns |
---|
| 3491 | before shifting them to one column to the left and back again. |
---|
| 3492 | The C<--shift> parameter must be 1, 2 or 3. |
---|
| 3493 | With C<--shift> egual to 2, the shift will be to two column to the left. |
---|
| 3494 | With 3, it will be 1 to the left and 2 to the left one time over two ! |
---|
| 3495 | In practise, we just add virtuals nodes in the dot file, |
---|
| 3496 | that means the result graph is generated with theses virtuals but invisibles nodes... |
---|
| 3497 | |
---|
| 3498 | =head2 ip-free |
---|
| 3499 | |
---|
| 3500 | klask ip-free [--verbose|-v] [--day|-d days-to-death] [--format|-f txt|html] [vlan_name] |
---|
| 3501 | |
---|
| 3502 | This command return IP address that was not use (detected by Klask) at this time. |
---|
| 3503 | The list returned could be limited to just one VLAN. |
---|
| 3504 | IP returned could have been never used or no computer have been detected since the number of days specified |
---|
| 3505 | (2 years by default). |
---|
| 3506 | This parameter could also be define in the configuration file F</etc/klask/klask.conf> (see L</CONFIGURATION>). |
---|
| 3507 | |
---|
| 3508 | default: |
---|
| 3509 | days-to-death: 730 |
---|
| 3510 | |
---|
| 3511 | Computer that does not have the good IP but takes a float one (see L</cleandb>) are taken into account. |
---|
| 3512 | |
---|
| 3513 | |
---|
| 3514 | =head2 bad-vlan-id |
---|
| 3515 | |
---|
| 3516 | klask bad-vlan-id [--day|-d days_before_alert] [--format|-f txt|html] |
---|
| 3517 | |
---|
| 3518 | This command return a list of switch port that are not configure with the good VLAN. |
---|
| 3519 | Computer which are in bad VLAN are detected with the float regex parameter (see L</cleandb>) |
---|
| 3520 | and another prior trace where they had the good IP (good DNS name). |
---|
| 3521 | The computer must stay connected on a bad VLAN more than XX days (15 days by default) before alert. |
---|
| 3522 | This parameter could also define in the configuration file F</etc/klask/klask.conf> (see L</CONFIGURATION>). |
---|
| 3523 | |
---|
| 3524 | default: |
---|
| 3525 | days-before-alert: 15 |
---|
| 3526 | |
---|
| 3527 | This functionality is not need if your switch use RADIUS 802.1X configuration... |

| 3532 | klask poe-enable [--verbose|-v] switch port |
---|
| 3533 | |
---|
| 3534 | This command activate the PoE (Power over Ethernet) on a switch port by SNMP. |
---|
| 3535 | So you need to give the switch name and a port on the command line. |
---|
| 3536 | See L</ABBREVIATION FOR PORT>. |

---|
| 3570 | =head1 CONFIGURATION |
---|
| 3571 | |
---|
| 3572 | Because Klask need many parameters, it's not possible actually to use command line parameters for everything. |
---|
| 3573 | The configuration is done in a F</etc/klask/klask.conf> YAML file. |
---|
| 3574 | This format have many advantage over XML, it's easier to read and to write ! |
---|
| 3575 | |
---|
| 3576 | Here an example, be aware with indent, it's important in YAML, do not use tabulation ! |

| 3629 | I think it's pretty easy to understand. |
---|
| 3630 | The default section can be overide in any section, if parameter mean something in theses sections. |
---|
| 3631 | Network to be scan are define in the network section. You must put an add by network. |
---|
| 3632 | Maybe I will make a delete line to suppress specific computers. |
---|
| 3633 | The switch section define your switch. |
---|
| 3634 | You have to write the port number to ignore, this was important if your switchs are cascades |
---|
| 3635 | (right now, method C<updatesw> find them automatically) |
---|
| 3636 | and is still important if you have loop (with PVST or MSTP). |
---|
| 3637 | Just put the ports numbers between switch. |
---|
| 3638 | |
---|
| 3639 | The C<community> parameter is use to get SNMP data on switch. |
---|
| 3640 | It could be overload for each switch. |
---|
| 3641 | By default, it's value is C<public> and you have to configure a readonly word for safety reason. |
---|
| 3642 | Some few command change the switch state as the commands L</enable> and L</disable>. |
---|
| 3643 | In theses rares cases, you need a readwrite SNMP community word define in your configuration file. |
---|
| 3644 | Klask then use since version C<0.6.2> the C<community-rw> parameter which by default is egal to C<private>. |

| 3647 | =head1 ABBREVIATION FOR PORT |
---|
| 3648 | |
---|
| 3649 | HP Procurve and Nexans switches have a simplistic numbering scheme. |
---|
| 3650 | It's just number: 1, 2, 3... 24. |
---|
| 3651 | On HP8000 chassis, ports names begin with an uppercase letter: A1, A2... |
---|
| 3652 | Nothing is done on theses ports names. |
---|
| 3653 | |
---|
| 3654 | On HP Comware and DELL, port digitization schema use a port speed word (generally a very verbose word) |
---|
| 3655 | followed by tree number. |
---|
| 3656 | In order to have short name, |
---|
| 3657 | we made the following rules: |
---|
| 3658 | |
---|
| 3659 | Bridge-Aggregation -> Br |
---|
| 3660 | FastEthernet -> Fa |
---|
| 3661 | Forty-GigabitEthernet -> Fo |
---|
| 3662 | FortyGigabitEthernet -> Fo |
---|
| 3663 | GigabitEthernet -> Gi |
---|
| 3664 | Giga -> Gi |
---|
| 3665 | Port-Channel -> Po |
---|
| 3666 | Ten-GigabitEthernet -> Te |
---|
| 3667 | TenGigabitEthernet -> Te |
---|
| 3668 | Ten -> Te |
---|
| 3669 | |
---|
| 3670 | All Klask command automatically normalize the port name on standart output |
---|
| 3671 | and also on input command line. |
---|
| 3672 | |
---|
| 3673 | In the case of use an aggregator port (Po, Tk, Br ...), |
---|
| 3674 | the real ports used are also return. |
---|
| 3675 | |
---|

| 3677 | =head1 SWITCH SUPPORTED |
---|
| 3678 | |
---|
| 3679 | Here is a list of switches where Klask gives or gave (for old switches) good results. |
---|
| 3680 | We have only a few manageable switches to actually test Klask. |
---|
| 3681 | It is quite possible that switches from other brands will work just as well. |
---|
| 3682 | You just have to do a test on it and add the line of description that goes well in the source code. |
---|
| 3683 | Contact us for any additional information. |
---|
| 3684 | |
---|
| 3685 | In the following list, the names of the switch types written in parentheses are the code names returned by Klask. |
---|
| 3686 | This makes it possible to adjust the code names of the different manufacturers! |
