2872
2873	=head1 DESCRIPTION
2874
2875	Klask is a small tool to find where is connected a host in a big network
2876	and on which VLAN.
2877	Klask mean search in brittany.
2878	No hight level protocol like CDL, LLDP are use.
2879	Everything is just done with SNMP request on MAC address.
2880
2881	Limitation : loop cannot be detected and could be problematic when the map is created (C<updatesw> method).
2882	If you use PVST or MSTP and create loop between VLAN,
2883	you have to use C<portignore> functionality on switch port to cut manually loop
2884	(see config file below).
2885
2886	When you use a management port to administrate a switch,
2887	it's not possible to create the map with this switch because it does not have a MAC address,
2888	so other switch cannot find the real downlink port...
2889	One way to work around this problem is, if you have a computer directly connected on the switch,
2890	to put this IP as the fake ip for the switch.
2891	The MAC address associated will be use just for the map detection.
2892	The C<fake-ip> parameter is defined in the config file.
2893
2894	Klask has now a web site dedicated for it: L<http://servforge.legi.grenoble-inp.fr/projects/klask>!
2895
2896
2897	=head1 COMMANDS
2898
2899	Some command are defined in the source code but are not documented here.
2900	Theses could be not well defined, not finished, not well tested...
2901	You can read the source code and use them at your own risk
2902	(like for all the Klask code).
2903
2904	=head2 search
2905
2906	klask search computer
2907
2908	This command takes one or more computer in argument.
2909	It search a computer on the network and give the port and the switch on which the computer is connected.
2910
2911	=head2 search-mac-on-switch
2912
2913	klask search-mac-on-switch [--verbose\|-v] [--vlan\|-i vlan-id] switch mac_addr
2914
2915	This command search a MAC address on a switch.
2916	To search on all switch, you could put C<'*'> or C<all>.
2917	The VLAN parameter could help.
2918
2919
2920	=head2 enable
2921
2922	klask enable [--verbose\|-v] switch port
2923
2924	This command activate a port (or an agrregate bridge port) on a switch by SNMP.
2925	So you need to give the switch name and a port on the command line.
2926	See L</ABBREVIATION FOR PORT>.
2927
2928	Warning: You need to have the SNMP write access on the switch in order to modify it's configuration.
2929
2930
2931	=head2 disable
2932
2933	klask disable [--verbose\|-v] switch port
2934
2935	This command deactivate a port (or an agrregate bridge port) on a switch by SNMP.
2936	So you need to give the switch name and a port on the command line.
2937	See L</ABBREVIATION FOR PORT>.
2938
2939	Warning: You need to have the SNMP write access on the switch in order to modify it's configuration.
2940
2941
2942	=head2 status
2943
2944	klask status [--verbose\|-v] switch port
2945
2946	This command return the status of a port number on a switch by SNMP.
2947	The return value could be C<enable> or C<disable> word.
2948	So you need to give the switch name and a port on the command line.
2949	See L</ABBREVIATION FOR PORT>.
2950
2951	If it's not possible to change port status with command L</enable> and L</disable>
2952	(SNMP community read write access),
2953	it's always possible to have the port status even for bridge agrregate port.
2954
2955
2956	=head2 updatedb
2957
2958	klask updatedb [--verbose\|-v] [--verb-description\|-d] [--chk-hostname\|-h] [--chk-location\|-l]
2959
2960	This command will scan networks and update the computer database.
2961	To know which are the cmputer scanned, you have to configure the file F</etc/klask/klask.conf>.
2962	This file is easy to read and write because Klask use YAML format and not XML
2963	(see L</CONFIGURATION>).
2964
2965	Option are not stable and could be use manually when you have a new kind of switch.
2966	Maybe some option will be transfered in a future C<checksw> command!
2967
2968	The network parameter C<scan-mode> can have two values: C<active> or C<passive>.
2969	By default, a network is C<active>.
2970	This means that an C<fping> command is done at the beginning on all the IP of the network
2971	and the computers that was not detected in this pass, but where their Klask entry is less than one week,
2972	will have an C<arping>
2973	(some OS do not respond to C<ping> but a computer have to respond to C<arping> if it want to interact with other).
2974	In the scan mode C<passive>, no C<fping> and no C<arping> are done.
2975	It's good for big subnet with few computer (telephone...).
2976	The idea of the C<active> scan mode is to force computer to regulary send packet over the network.
2977
2978	=head2 exportdb
2979
2980	klask exportdb [--format\|-f txt\|html]
2981
2982	This command print the content of the computer database.
2983	There is actually only two format : TXT and HTML.
2984	By default, format is TXT.
2985	It's very easy to have more format, it's just need times...
2986
2987	=head2 removedb
2988
2989	klask removedb IP* computer*
2990
2991	This command remove an entry in the database.
2992	There is only one kind of parameter, the IP of the computers to be removed.
2993	You can put as many IP as you want...
2994
2995	Computer DNS names are also a valid entry because a DNS resolver is executed at the beginning.
2996
2997	=head2 cleandb
2998
2999	klask cleandb [--verbose\|-v] --day number_of_day --repair-dns
3000
3001	Remove double entry (same MAC-Address) in the computer database when the older one is older than X day (C<--day>) the new one.
3002	Computer name beginning by 'float' (regex C<^float>) are not really taken into account but could be remove.
3003	This could be configure with the global regex parameter C<float-regex> in the configuration file F</etc/klask/klask.conf>.
3004	This functionality could be use when computer define in VLAN 1
3005	could have a float IP when they are connected on VLAN 2.
3006	In the Klask database, the float DNS entries are less important.
3007
3008	When reverse DNS has not been done by the past, option C<--repair-dns> force a reverse DNS check on all unkown host.
3009
3010	=head2 updatesw
3011
3012	klask updatesw [--verbose\|-v]
3013
3014	This command build a map of your manageable switch on your network.
3015	The list of the switches must be given in the file F</etc/klask/klask.conf> (see L</CONFIGURATION>).
3016
3017
3018	=head2 exportsw
3019
3020	klask exportsw [--format\|-f txt\|dot]
3021
3022	This command print the content of the switch database. There is actually two format.
3023	One is just TXT for terminal and the other is the DOT format from the graphviz environnement.
3024	By default, format is TXT.
3025
3026	klask exportsw --format dot > /tmp/map.dot
3027	dot -Tpng /tmp/map.dot > /tmp/map.png
3028
3029
3030	=head2 ip-free
3031
3032	klask ip-free [--verbose\|-v] [--day\|-d days-to-death] [--format\|-f txt\|html] [vlan_name]
3033
3034	This command return IP address that was not use (detected by Klask) at this time.
3035	The list returned could be limited to just one VLAN.
3036	IP returned could have been never used or no computer have been detected since the number of days specified
3037	(2 years by default).
3038	This parameter could also be define in the configuration file F</etc/klask/klask.conf> (see L</CONFIGURATION>).
3039
3040	default:
3041	days-to-death: 730
3042
3043	Computer that does not have the good IP but takes a float one (see L</cleandb>) are taken into account.
3044
3045
3046	=head2 bad-vlan-id
3047
3048	klask bad-vlan-id [--day\|-d days_before_alert]
3049
3050	This command return a list of switch port that are not configure with the good VLAN.
3051	Computer which are in bad VLAN are detected with the float regex parameter (see L</cleandb>)
3052	and another prior trace where they had the good IP (good DNS name).
3053	The computer must stay connected on a bad VLAN more than XX days (15 days by default) before alert.
3054	This parameter could also define in the configuration file F</etc/klask/klask.conf> (see L</CONFIGURATION>).
3055
3056	default:
3057	days-before-alert: 15
3058
3059	This functionality is not need if your switch use RADIUS 802.1X configuration...
3060
3061
3062	=head2 poe-enable
3063
3064	klask poe-enable [--verbose\|-v] switch port
3065
3066	This command activate the PoE (Power over Ethernet) on a switch port by SNMP.
3067	So you need to give the switch name and a port on the command line.
3068	See L</ABBREVIATION FOR PORT>.
3069
3070	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3071	You need to have the SNMP write access on the switch in order to modify it's configuration.
3072
3073
3074	=head2 poe-disable
3075
3076	klask poe-disable [--verbose\|-v] switch port
3077
3078	This command deactivate the PoE (Power over Ethernet) on a switch port by SNMP.
3079	So you need to give the switch name and a port on the command line.
3080	See L</ABBREVIATION FOR PORT>.
3081
3082	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3083	You need to have the SNMP write access on the switch in order to modify it's configuration.
3084
3085
3086	=head2 poe-status
3087
3088	klask poe-status [--verbose\|-v] switch port
3089
3090	This command return the status of the PoE (Power over Ethernet) on a switch port by SNMP.
3091	The return value could be C<enable> or C<disable> word.
3092	So you need to give the switch name and a port on the command line.
3093	See L</ABBREVIATION FOR PORT>.
3094
3095	If it's not possible to change the PoE status with command L</poe-enable> and L</poe-disable>
3096	(SNMP community read write access),
3097	it's always possible to have the PoE port status.
3098
3099	Warning: Only NEXANS switches are supported (we do not have other switch for testing).
3100
3101
3102	=head1 CONFIGURATION
3103
3104	Because Klask need many parameters, it's not possible actually to use command line parameters for everything.
3105	The configuration is done in a F</etc/klask/klask.conf> YAML file.
3106	This format have many advantage over XML, it's easier to read and to write !

3161	I think it's pretty easy to understand.
3162	The default section can be overide in any section, if parameter mean something in theses sections.
3163	Network to be scan are define in the network section. You must put an add by network.
3164	Maybe I will make a delete line to suppress specific computers.
3165	The switch section define your switch.
3166	You have to write the port number to ignore, this was important if your switchs are cascades
3167	(right now, method C<updatesw> find them automatically)
3168	and is still important if you have loop (with PVST or MSTP).
3169	Just put the ports numbers between switch.
3170
3171	The C<community> parameter is use to get SNMP data on switch.
3172	It could be overload for each switch.
3173	By default, it's value is C<public> and you have to configure a readonly word for safety reason.
3174	Some few command change the switch state as the commands L</enable> and L</disable>.
3175	In theses rares cases, you need a readwrite SNMP community word define in your configuration file.
3176	Klask then use since version C<0.6.2> the C<community-rw> parameter which by default is egal to C<private>.

3179	=head1 ABBREVIATION FOR PORT
3180
3181	HP Procurve and Nexans switches have a simplistic numbering scheme.
3182	It's just number: 1, 2, 3... 24.
3183	On HP8000 chassis, ports names begin with an uppercase letter: A1, A2...
3184	Nothing is done on theses ports names.
3185
3186	On HP Comware and DELL, port digitization schema use a port speed word (generally a very verbose word)
3187	followed by tree number.
3188	In order to have short name,
3189	we made the following rules:
3190
3191	Bridge-Aggregation -> Br
3192	FastEthernet -> Fa
3193	Forty-GigabitEthernet -> Fo
3194	FortyGigabitEthernet -> Fo
3195	GigabitEthernet -> Gi
3196	Giga -> Gi
3197	Port-Channel -> Po
3198	Ten-GigabitEthernet -> Te
3199	TenGigabitEthernet -> Te
3200	Ten -> Te
3201
3202	All Klask command automatically normalize the port name on standart output
3203	and also on input command line.
3204
3205	In the case of use an aggregator port (Po, Tk, Br ...),
3206	the real ports used are also return.
