2492	=head1 DESCRIPTION
2493
2494	klask is a small tool to find where is a host in a big network. klask mean search in brittany.
2495	No hight level protocol like CDL, LLDP are use.
2496	Everything is just done with SNMP request on MAC address.
2497
2498	Limitation : loop cannot be detected and could be problematic when create the map.
2499	If you use PVST or MSTP and create loop between VLAN,
2500	you have to use portignore functionality on switch port to cut manually loop
2501	(see config file below).
2502
2503	When you use a management port to administrate the switch,
2504	it's not possible to create the map because the switch doesn't have a MAC address,
2505	so other switch cannot find downlink port...
2506	A way is if you have a computer directly connected on the switch is to put this IP as the fake ip for the switch.
2507	The MAC address associated will be use just for the map detection.
2508	The fake-ip parameter is defined in the config file.
2509
2510	Klask has now a web site dedicated for it !
2511

2513
2514
2515	=head1 COMMANDS
2516
2517
2518	=head2 search
2519
2520	This command takes one or more computer in argument.
2521	It search a computer on the network and give the port and the switch on which the computer is connected.
2522
2523
2524	=head2 enable
2525
2526	This command activate a port on a switch by SNMP.
2527	So you need to give the switch and the port number on the command line.
2528
2529
2530	=head2 disable
2531
2532	This command deactivate a port on a switch by SNMP.
2533	So you need to give the switch and the port number on the command line.
2534
2535
2536	=head2 status
2537
2538	This command return the status of a port number on a switch by SNMP.
2539	So you need to give the switch name and the port number on the command line.
2540
2541
2542	=head2 updatedb
2543
2544	This command will scan networks and update a database.
2545	To know which are the cmputer scan, you have to configure the file F</etc/klask/klask.conf>.
2546	This file is easy to read and write because klask use YAML format and not XML.
2547
2548
2549	=head2 exportdb --format [txt\|html]
2550
2551	This command print the content of the database. There is actually only one format.
2552	It's very easy to have more format, it's just need times...
2553
2554	=head2 removedb
2555
2556	This command remove an entry in the database.
2557	There is only one kind of parameter, the IP of the computers to be removed.
2558	You can put as many IP as you want...
2559
2560	DNS computer name could also a valid entry because a DNS resolver is done at the beginning.
2561
2562	=head2 cleandb
2563
2564	Remove double entry (same MAC-Address) when the older one is older than X day (--day) the new one.
2565	Computer name beginning by 'float' are not really taken into account but could be remove.
2566
2567	When reverse DNS has not be done, option --repair-dns force reverse DNS check on unkown host.
2568
2569	=head2 updatesw
2570
2571	This command build a map of your manageable switch on your network.
2572	The list of the switch must be given in the file F</etc/klask/klask.conf>.
2573
2574
2575	=head2 exportsw --format [txt\|dot]
2576
2577	This command print the content of the switch database. There is actually two format.
2578	One is just txt for terminal and the other is the dot format from the graphviz environnement.
2579
2580	klask exportsw --format dot > /tmp/map.dot
2581	dot -Tpng /tmp/map.dot > /tmp/map.png
2582
2583
2584
2585	=head1 CONFIGURATION
2586
2587	Because klask need many parameters, it's not possible actually to use command line parameters for everything.
2588	The configuration is done in a F</etc/klask/klask.conf> YAML file.
2589	This format have many advantage over XML, it's easier to read and to write !
2590
2591	Here an example, be aware with indent, it's important in YAML, do not use tabulation !

2627
2628	I think it's pretty easy to understand.
2629	The default section can be overide in any section, if parameter mean something in theses sections.
2630	Network to be scan are define in the network section. You must put a add by network.
2631	Maybe i will make a delete line to suppress specific computers.
2632	The switch section define your switch.
2633	You have to write the port number to ignore, this is important if your switchs are cascade.
2634	Juste put the ports numbers between switch.
