2550	=head1 DESCRIPTION
2551
2552	Klask is a small tool to find where is a host in a big network.
2553	Klask mean search in brittany.
2554	No hight level protocol like CDL, LLDP are use.
2555	Everything is just done with SNMP request on MAC address.
2556
2557	Limitation : loop cannot be detected and could be problematic when the map is created (C<updatesw> method).
2558	If you use PVST or MSTP and create loop between VLAN,
2559	you have to use C<portignore> functionality on switch port to cut manually loop
2560	(see config file below).
2561
2562	When you use a management port to administrate a switch,
2563	it's not possible to create the map with this switch because it does not have a MAC address,
2564	so other switch cannot find the real downlink port...
2565	One way to work around this problem is, if you have a computer directly connected on the switch,
2566	to put this IP as the fake ip for the switch.
2567	The MAC address associated will be use just for the map detection.
2568	The C<fake-ip> parameter is defined in the config file.
2569
2570	Klask has now a web site dedicated for it !

2573
2574
2575	=head1 COMMANDS
2576
2577
2578	=head2 search
2579
2580	This command takes one or more computer in argument.
2581	It search a computer on the network and give the port and the switch on which the computer is connected.
2582
2583
2584	=head2 enable
2585
2586	This command activate a port on a switch by SNMP.
2587	So you need to give the switch and the port number on the command line.
2588	Actually, port number must be a number and not the name alias...
2589
2590
2591	=head2 disable
2592
2593	This command deactivate a port on a switch by SNMP.
2594	So you need to give the switch and the port number on the command line.
2595	Actually, port number must be a number and not the name alias...
2596
2597
2598	=head2 status
2599
2600	This command return the status of a port number on a switch by SNMP.
2601	So you need to give the switch name and the port number on the command line.
2602	Actually, port number must be a number and not the name alias...
2603
2604
2605	=head2 updatedb
2606
2607	This command will scan networks and update a database.
2608	To know which are the cmputer scan, you have to configure the file F</etc/klask/klask.conf>.
2609	This file is easy to read and write because klask use YAML format and not XML.
2610
2611
2612	=head2 exportdb --format [txt\|html]
2613
2614	This command print the content of the database. There is actually only one format.
2615	It's very easy to have more format, it's just need times...
2616
2617	=head2 removedb
2618
2619	This command remove an entry in the database.
2620	There is only one kind of parameter, the IP of the computers to be removed.
2621	You can put as many IP as you want...
2622
2623	DNS computer name could also a valid entry because a DNS resolver is done at the beginning.
2624
2625	=head2 cleandb
2626
2627	Remove double entry (same MAC-Address) when the older one is older than X day (C<--day>) the new one.
2628	Computer name beginning by 'float' are not really taken into account but could be remove.
2629
2630	When reverse DNS has not be done, option --repair-dns force reverse DNS check on unkown host.
2631
2632	=head2 updatesw
2633
2634	This command build a map of your manageable switch on your network.
2635	The list of the switch must be given in the file F</etc/klask/klask.conf>.
2636
2637
2638	=head2 exportsw --format [txt\|dot]
2639
2640	This command print the content of the switch database. There is actually two format.
2641	One is just txt for terminal and the other is the dot format from the graphviz environnement.
2642
2643	klask exportsw --format dot > /tmp/map.dot
2644	dot -Tpng /tmp/map.dot > /tmp/map.png
2645
2646
2647
2648	=head1 CONFIGURATION
2649
2650	Because klask need many parameters, it's not possible actually to use command line parameters for everything.
2651	The configuration is done in a F</etc/klask/klask.conf> YAML file.
2652	This format have many advantage over XML, it's easier to read and to write !
2653
2654	Here an example, be aware with indent, it's important in YAML, do not use tabulation !

2690
2691	I think it's pretty easy to understand.
2692	The default section can be overide in any section, if parameter mean something in theses sections.
2693	Network to be scan are define in the network section. You must put an add by network.
2694	Maybe I will make a delete line to suppress specific computers.
2695	The switch section define your switch.
2696	You have to write the port number to ignore, this was important if your switchs are cascade
2697	(right now, method C<updatesw> find them automatically)
2698	and is still important if you have loop (with PVST or MSTP).
2699	Just put the ports numbers between switch.
