3326
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...
3528
3529
3530	=head2 poe-enable
3531
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>.
3537
3538	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3539	You need to have the SNMP write access on the switch in order to modify it's configuration.
3540
3541
3542	=head2 poe-disable
3543
3544	klask poe-disable [--verbose\|-v] switch port
3545
3546	This command deactivate the PoE (Power over Ethernet) on a switch port by SNMP.
3547	So you need to give the switch name and a port on the command line.
3548	See L</ABBREVIATION FOR PORT>.
3549
3550	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3551	You need to have the SNMP write access on the switch in order to modify it's configuration.
3552
3553
3554	=head2 poe-status
3555
3556	klask poe-status [--verbose\|-v] switch port
3557
3558	This command return the status of the PoE (Power over Ethernet) on a switch port by SNMP.
3559	The return value could be C<enable> or C<disable> word.
3560	So you need to give the switch name and a port on the command line.
3561	See L</ABBREVIATION FOR PORT>.
3562
3563	If it's not possible to change the PoE status with command L</poe-enable> and L</poe-disable>
3564	(SNMP community read write access),
3565	it's always possible to have the PoE port status.
3566
3567	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3568
3569
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 !
3577

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>.
3645
3646
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
3676
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!
