3456	=head1 DESCRIPTION
3457
3458	Klask is a small tool to find where is connected a host in a big network
3459	and on which VLAN.
3460	Klask mean search in brittany.
3461	No hight level protocol like CDL, LLDP are use.
3462	Everything is just done with SNMP request on MAC address.

3464	Limitation : loop cannot be detected and could be problematic when the map is created (C<updatesw> method).
3465	If you use PVST or MSTP and create loop between VLAN,
3466	you have to use C<portignore> functionality on switch port to cut manually loop
3467	(see config file below).
3468
3469	When you use a management port to administrate a switch,
3470	it's not possible to create the map with this switch because it does not have a MAC address,
3471	so other switch cannot find the real downlink port...
3472	One way to work around this problem is, if you have a computer directly connected on the switch,
3473	to put this IPv4 as the fake ip for the switch.
3474	The MAC address associated will be use just for the map detection.
3475	The C<fake-ip> parameter is defined in the config file.
3476
3477	Klask has now a web site dedicated for it: L<http://servforge.legi.grenoble-inp.fr/projects/klask>!
3478
3479
3480	=head1 COMMANDS
3481
3482	Some command are defined in the source code but are not documented here.
3483	Theses could be not well defined, not finished, not well tested...
3484	You can read the source code and use them at your own risk
3485	(like for all the Klask code).
3486
3487	=head2 search
3488
3489	klask search computer
3490
3491	This command takes one or more computer in argument.
3492	It search a computer on the network and give the port and the switch on which the computer is connected.
3493
3494	=head2 search-mac-on-switch
3495
3496	klask search-mac-on-switch [--verbose\|-v] [--vlan\|-i vlan-id] switch mac_addr
3497
3498	This command search a MAC address on a switch.
3499	To search on all switch, you could put C<'*'> or C<all>.
3500	The VLAN parameter could help.
3501
3502
3503	=head2 enable
3504
3505	klask enable [--verbose\|-v] switch port
3506
3507	This command activate a port (or an agrregate bridge port) on a switch by SNMP.
3508	So you need to give the switch name and a port on the command line.
3509	See L</ABBREVIATION FOR PORT>.
3510
3511	Warning: You need to have the SNMP write access on the switch in order to modify it's configuration.
3512
3513
3514	=head2 disable
3515
3516	klask disable [--verbose\|-v] switch port
3517
3518	This command deactivate a port (or an agrregate bridge port) on a switch by SNMP.
3519	So you need to give the switch name and a port on the command line.
3520	See L</ABBREVIATION FOR PORT>.
3521
3522	Warning: You need to have the SNMP write access on the switch in order to modify it's configuration.
3523
3524
3525	=head2 status
3526
3527	klask status [--verbose\|-v] switch port
3528
3529	This command return the status of a port number on a switch by SNMP.
3530	The return value could be C<enable> or C<disable> word.
3531	So you need to give the switch name and a port on the command line.
3532	See L</ABBREVIATION FOR PORT>.
3533
3534	If it's not possible to change port status with command L</enable> and L</disable>
3535	(SNMP community read write access),
3536	it's always possible to have the port status even for bridge agrregate port.
3537
3538
3539	=head2 updatedb
3540
3541	klask updatedb [--verbose\|-v] [--verb-description\|-d] [--chk-hostname\|-h] [--chk-location\|-l] [--no-rebuildsw\|-R]
3542
3543	This command will scan networks and update the computer database.
3544	To know which are the cmputer scanned, you have to configure the file F</etc/klask/klask.conf>.
3545	This file is easy to read and write because Klask use YAML format and not XML
3546	(see L</CONFIGURATION>).
3547
3548	Option are not stable and could be use manually when you have a new kind of switch.
3549	Maybe some option will be transfered in a future C<checksw> command!
3550
3551	The network parameter C<scan-mode> can have two values: C<active> or C<passive>.
3552	By default, a network is C<active>.
3553	This means that an C<fping> command is done at the beginning on all the IPv4 of the network
3554	and the computers that was not detected in this pass, but where their Klask entry is less than one week,
3555	will have an C<arping>
3556	(some OS do not respond to C<ping> but a computer have to respond to C<arping> if it want to interact with other).
3557	In the scan mode C<passive>, no C<fping> and no C<arping> are done.
3558	It's good for big subnet with few computer (telephone...).
3559	The idea of the C<active> scan mode is to force computer to regulary send packet over the network.
3560
3561	At the beginning, the command verify that the switch map checksum is always valid.
3562	Otherwise, a rebuild procedure will ne done automatically.
3563
3564	=head2 exportdb
3565
3566	klask exportdb [--format\|-f txt\|html]
3567
3568	This command print the content of the computer database.
3569	There is actually only two format : TXT and HTML.
3570	By default, format is TXT.
3571	It's very easy to have more format, it's just need times...
3572
3573	=head2 removedb
3574
3575	klask removedb ipv4_addr* computer*
3576
3577	This command remove an entry in the database.
3578	There is only one kind of parameter, the IPv4 of the computers to be removed.
3579	You can put as many IPv4 as you want...
3580
3581	Computer DNS names are also a valid entry because a DNS resolver is executed at the beginning.
3582
3583	=head2 insertdb
3584
3585	klask insertdb --ip ipv4_addr --mac mac_addr --network vlan_name
3586
3587	This command insert an entry in the database.
3588	The IPv4 must not exist previously in the database
3589	and the DNS resolution name muts be active.
3590
3591	The date or timestamp of the entry will be C<number_of_day> in the past (see L<cleandb>)
3592	from today or from the oldest entry with the same MAC-Address.
3593	This command can be use to add pseudo entry and help in the process to detect bad vlan configuration (see L<bad-vlan-id>).
3594
3595	=head2 cleandb
3596
3597	klask cleandb [--verbose\|-v] --day number_of_day --repair-dns
3598
3599	Remove double entry (same MAC-Address) in the computer database when the older one is older than X day (C<--day>) the new one.
3600	Computer name beginning by 'float' (regex C<^float>) are not really taken into account but could be remove.
3601	This could be configure with the global regex parameter C<float-regex> in the configuration file F</etc/klask/klask.conf>.
3602	This functionality could be use when computer define in VLAN 1
3603	could have a float IPv4 when they are connected on VLAN 2.
3604	In the Klask database, the float DNS entries are less important.
3605
3606	When reverse DNS has not been done by the past, option C<--repair-dns> force a reverse DNS check on all unkown host.
3607
3608	=head2 updatesw
3609
3610	klask updatesw [--verbose\|-v]
3611
3612	This command build a map of your manageable switch on your network.
3613	The list of the switches must be given in the file F</etc/klask/klask.conf> (see L</CONFIGURATION>).
3614
3615	The database has a checksum which depend of all the active switches.
3616	It's use when rebuilding the database in case of change in switch configuration (one more for example).
3617
3618	=head2 exportsw
3619
3620	klask exportsw [--format\|-f txt\|dot] [--modulo\|-m XX] [--shift\|-s YY] [--way all\|desc\|child\|parent] [--no-header\|-H]
3621
3622	This command print the content of the switch database. There is actually two format.
3623	One is just TXT for terminal and the other is the DOT format from the graphviz environnement.
3624	By default, format is TXT.
3625
3626	B<Options for TXT format:>
3627
3628	Tree tables are print :
3629	C<desc> gives the switches description, model and revision,
3630	C<child> return the switch to parent switch table and
3631	C<parent> return the switch parent to parent child table.
3632	With option C<--way>, you can choose which on to print.
3633	C<all> will print all and C<child,parent> will print only C<child> and C<parent> table.
3634	With option C<--no-header>, you can remove the header for each table.
3635
3636	B<Options for DOT format:>
3637
3638	klask exportsw --format dot > /tmp/map.dot
3639	dot -Tpng /tmp/map.dot > /tmp/map.png
3640
3641	In case you have too many switch connected on one switch,
3642	the graphviz result graph could be too much vertical.
3643	With C<--modulo> > 0, you can specify how many switches (connected on one switch) are on the same columns
3644	before shifting them to one column to the left and back again.
3645	The C<--shift> parameter must be 1, 2 or 3.
3646	With C<--shift> egual to 2, the shift will be to two column to the left.
3647	With 3, it will be 1 to the left and 2 to the left one time over two !
3648	In practise, we just add virtuals nodes in the dot file,
3649	that means the result graph is generated with theses virtuals but invisibles nodes...
3650
3651	=head2 ip-free
3652
3653	klask ip-free [--verbose\|-v] [--day\|-d days-to-death] [--format\|-f txt\|html] [vlan_name]
3654
3655	This command return IPv4 address that was not use (detected by Klask) at this time.
3656	The list returned could be limited to just one VLAN.
3657	IP returned could have been never used or no computer have been detected since the number of days specified
3658	(2 years by default).
3659	This parameter could also be define in the configuration file F</etc/klask/klask.conf> (see L</CONFIGURATION>).
3660
3661	default:
3662	days-to-death: 730
3663
3664	Computer that does not have the good IPv4 but takes a float one (see L</cleandb>) are taken into account.
3665
3666
3667	=head2 bad-vlan-id
3668
3669	klask bad-vlan-id [--day\|-d days_before_alert] [--format\|-f txt\|html]
3670
3671	This command return a list of switch port that are not configure with the good VLAN.
3672	Computer which are in bad VLAN are detected with the float regex parameter (see L</cleandb>)
3673	and another prior trace where they had the good IPv4 (good DNS name).
3674	The computer must stay connected on a bad VLAN more than XX days (15 days by default) before alert.
3675	This parameter could also define in the configuration file F</etc/klask/klask.conf> (see L</CONFIGURATION>).
3676
3677	default:
3678	days-before-alert: 15
3679
3680	This functionality is not need if your switch use RADIUS 802.1X configuration...
3681
3682
3683	=head2 poe-enable
3684
3685	klask poe-enable [--verbose\|-v] switch port
3686
3687	This command activate the PoE (Power over Ethernet) on a switch port by SNMP.
3688	So you need to give the switch name and a port on the command line.
3689	See L</ABBREVIATION FOR PORT>.
3690
3691	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3692	You need to have the SNMP write access on the switch in order to modify it's configuration.
3693
3694
3695	=head2 poe-disable
3696
3697	klask poe-disable [--verbose\|-v] switch port
3698
3699	This command deactivate the PoE (Power over Ethernet) on a switch port by SNMP.
3700	So you need to give the switch name and a port on the command line.
3701	See L</ABBREVIATION FOR PORT>.
3702
3703	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3704	You need to have the SNMP write access on the switch in order to modify it's configuration.
3705
3706
3707	=head2 poe-status
3708
3709	klask poe-status [--verbose\|-v] switch port
3710
3711	This command return the status of the PoE (Power over Ethernet) on a switch port by SNMP.
3712	The return value could be C<enable> or C<disable> word.
3713	So you need to give the switch name and a port on the command line.
3714	See L</ABBREVIATION FOR PORT>.
3715
3716	If it's not possible to change the PoE status with command L</poe-enable> and L</poe-disable>
3717	(SNMP community read write access),
3718	it's always possible to have the PoE port status.
3719
3720	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3721
3722
3723	=head1 CONFIGURATION
3724
3725	Because Klask need many parameters, it's not possible actually to use command line parameters for everything.
3726	The configuration is done in a F</etc/klask/klask.conf> YAML file.
3727	This format have many advantage over XML, it's easier to read and to write !
3728
3729	Here an example, be aware with indent, it's important in YAML, do not use tabulation !

3782	I think it's pretty easy to understand.
3783	The default section can be overide in any section, if parameter mean something in theses sections.
3784	Network to be scan are define in the network section. You must put an add by network.
3785	Maybe I will make a delete line to suppress specific computers.
3786	The switch section define your switch.
3787	You have to write the port number to ignore, this was important if your switchs are cascades
3788	(right now, method C<updatesw> find them automatically)
3789	and is still important if you have loop (with PVST or MSTP).
3790	Just put the ports numbers between switch.
3791
3792	The C<community> parameter is use to get SNMP data on switch.
3793	It could be overload for each switch.
3794	By default, it's value is C<public> and you have to configure a readonly word for safety reason.
3795	Some few command change the switch state as the commands L</enable> and L</disable>.
3796	In theses rares cases, you need a readwrite SNMP community word define in your configuration file.
3797	Klask then use since version C<0.6.2> the C<community-rw> parameter which by default is egal to C<private>.
3798
3799
3800	=head1 ABBREVIATION FOR PORT
3801
3802	HP Procurve and Nexans switches have a simplistic numbering scheme.
3803	It's just number: 1, 2, 3... 24.
3804	On HP8000 chassis, ports names begin with an uppercase letter: A1, A2...
3805	Nothing is done on theses ports names.
3806
3807	On HP Comware and DELL, port digitization schema use a port speed word (generally a very verbose word)
3808	followed by tree number.
3809	In order to have short name,
3810	we made the following rules:
3811
3812	Bridge-Aggregation -> Br
3813	FastEthernet -> Fa
3814	Forty-GigabitEthernet -> Fo
3815	FortyGigabitEthernet -> Fo
3816	GigabitEthernet -> Gi
3817	Giga -> Gi
3818	Port-Channel -> Po
3819	Ten-GigabitEthernet -> Te
3820	TenGigabitEthernet -> Te
3821	Ten -> Te
3822
3823	All Klask command automatically normalize the port name on standart output
3824	and also on input command line.
3825
3826	In the case of use an aggregator port (Po, Tk, Br ...),
3827	the real ports used are also return.
3828
3829
3830	=head1 SWITCH SUPPORTED
3831
3832	Here is a list of switches where Klask gives or gave (for old switches) good results.
3833	We have only a few manageable switches to actually test Klask.
3834	It is quite possible that switches from other brands will work just as well.
3835	You just have to do a test on it and add the line of description that goes well in the source code.
3836	Contact us for any additional information.
3837
3838	In the following list, the names of the switch types written in parentheses are the code names returned by Klask.
