Klask mean search in brittany. No hight level protocol like CDL, LLDP are use. Everything is just done with SNMP request on MAC address. Limitation : loop cannot be detected and could be problematic when the map is created (C method). If you use PVST or MSTP and create loop between VLAN, you have to use C functionality on switch port to cut manually loop (see config file below). When you use a management port to administrate a switch, it's not possible to create the map with this switch because it does not have a MAC address, so other switch cannot find the real downlink port... One way to work around this problem is, if you have a computer directly connected on the switch, to put this IP as the fake ip for the switch. The MAC address associated will be use just for the map detection. The C parameter is defined in the config file. Klask has now a web site dedicated for it: L! =head1 COMMANDS Some command are defined in the source code but are not documented here. Theses could be not well defined, not finished, not well tested... You can read the source code and use them at your own risk (like for all the Klask code). =head2 search klask search computer This command takes one or more computer in argument. It search a computer on the network and give the port and the switch on which the computer is connected. =head2 search-mac-on-switch klask search-mac-on-switch [--verbose|-v] [--vlan|-i vlan-id] switch mac_addr This command search a MAC address on a switch. To search on all switch, you could put C<'*'> or C. The VLAN parameter could help. =head2 enable klask enable [--verbose|-v] switch port This command activate a port (or an agrregate bridge port) on a switch by SNMP. So you need to give the switch name and a port on the command line. See L. Warning: You need to have the SNMP write access on the switch in order to modify it's configuration. =head2 disable klask disable [--verbose|-v] switch port This command deactivate a port (or an agrregate bridge port) on a switch by SNMP. So you need to give the switch name and a port on the command line. See L. Warning: You need to have the SNMP write access on the switch in order to modify it's configuration. =head2 status klask status [--verbose|-v] switch port This command return the status of a port number on a switch by SNMP. The return value could be C or C word. So you need to give the switch name and a port on the command line. See L. If it's not possible to change port status with command L and L (SNMP community read write access), it's always possible to have the port status even for bridge agrregate port. =head2 updatedb klask updatedb [--verbose|-v] [--verb-description|-d] [--chk-hostname|-h] [--chk-location|-l] This command will scan networks and update the computer database. To know which are the cmputer scanned, you have to configure the file F. This file is easy to read and write because Klask use YAML format and not XML (see L). Option are not stable and could be use manually when you have a new kind of switch. Maybe some option will be transfered in a future C command! The network parameter C can have two values: C or C. By default, a network is C. This means that an C command is done at the beginning on all the IP of the network and the computers that was not detected in this pass, but where their Klask entry is less than one week, will have an C (some OS do not respond to C but a computer have to respond to C if it want to interact with other). In the scan mode C, no C and no C are done. It's good for big subnet with few computer (telephone...). The idea of the C scan mode is to force computer to regulary send packet over the network. =head2 exportdb klask exportdb [--format|-f txt|html] This command print the content of the computer database. There is actually only two format : TXT and HTML. By default, format is TXT. It's very easy to have more format, it's just need times... =head2 removedb klask removedb IP* computer* This command remove an entry in the database. There is only one kind of parameter, the IP of the computers to be removed. You can put as many IP as you want... Computer DNS names are also a valid entry because a DNS resolver is executed at the beginning. =head2 cleandb klask cleandb [--verbose|-v] --day number_of_day --repair-dns Remove double entry (same MAC-Address) in the computer database when the older one is older than X day (C<--day>) the new one. Computer name beginning by 'float' (regex C<^float>) are not really taken into account but could be remove. This could be configure with the global regex parameter C in the configuration file F. This functionality could be use when computer define in VLAN 1 could have a float IP when they are connected on VLAN 2. In the Klask database, the float DNS entries are less important. When reverse DNS has not been done by the past, option C<--repair-dns> force a reverse DNS check on all unkown host. =head2 updatesw klask updatesw [--verbose|-v] This command build a map of your manageable switch on your network. The list of the switches must be given in the file F (see L). =head2 exportsw klask exportsw [--format|-f txt|dot] This command print the content of the switch database. There is actually two format. One is just TXT for terminal and the other is the DOT format from the graphviz environnement. By default, format is TXT. klask exportsw --format dot > /tmp/map.dot dot -Tpng /tmp/map.dot > /tmp/map.png =head2 ip-free klask ip-free [--verbose|-v] [--day|-d days-to-death] [--format|-f txt|html] [vlan_name] This command return IP address that was not use (detected by Klask) at this time. The list returned could be limited to just one VLAN. IP returned could have been never used or no computer have been detected since the number of days specified (2 years by default). This parameter could also be define in the configuration file F (see L). default: days-to-death: 730 Computer that does not have the good IP but takes a float one (see L) are taken into account. =head2 bad-vlan-id klask bad-vlan-id [--day|-d days_before_alert] This command return a list of switch port that are not configure with the good VLAN. Computer which are in bad VLAN are detected with the float regex parameter (see L) and another prior trace where they had the good IP (good DNS name). The computer must stay connected on a bad VLAN more than XX days (15 days by default) before alert. This parameter could also define in the configuration file F (see L). default: days-before-alert: 15 This functionality is not need if your switch use RADIUS 802.1X configuration... =head1 CONFIGURATION Because Klask need many parameters, it's not possible actually to use command line parameters for everything. The configuration is done in a F YAML file. This format have many advantage over XML, it's easier to read and to write ! Here an example, be aware with indent, it's important in YAML, do not use tabulation ! default: community: public community-rw: private snmpport: 161 float-regex: '(?^msx: ^float )' scan-mode: active network: labnet: ip-subnet: - add: 192.168.1.0/24 - add: 192.168.2.0/24 interface: eth0 vlan-id: 12 main-router: gw1.labnet.local schoolnet: ip-subnet: - add: 192.168.3.0/24 - add: 192.168.4.0/24 interface: eth0.38 vlan-id: 13 main-router: gw2.schoolnet.local scan-mode: passive etunet: ip-subnet: - add: 192.168.5.0/24 interface: eth2 vlan-id: 14 main-router: gw3.etunet.local scan-mode: passive switch: - hostname: sw1.klask.local location: BatY / 1 floor / K004 portignore: - 1 - 2 - hostname: sw2.klask.local location: BatY / 2 floor / K203 type: HP2424 portignore: - 1 - 2 fake-ip: 192.168.9.14 - hostname: sw3.klask.local location: BatY / 2 floor / K203 I think it's pretty easy to understand. The default section can be overide in any section, if parameter mean something in theses sections. Network to be scan are define in the network section. You must put an add by network. Maybe I will make a delete line to suppress specific computers. The switch section define your switch. You have to write the port number to ignore, this was important if your switchs are cascades (right now, method C find them automatically) and is still important if you have loop (with PVST or MSTP). Just put the ports numbers between switch. The C parameter is use to get SNMP data on switch. It could be overload for each switch. By default, it's value is C and you have to configure a readonly word for safety reason. Some few command change the switch state as the commands L and L. In theses rares cases, you need a readwrite SNMP community word define in your configuration file. Klask then use since version C<0.6.2> the C parameter which by default is egal to C. =head1 ABBREVIATION FOR PORT HP Procurve and Nexans switches have a simplistic numbering scheme. It's just number: 1, 2, 3... 24. On HP8000 chassis, ports names begin with an uppercase letter: A1, A2... Nothing is done on theses ports names. On HP Comware and DELL, port digitization schema use a port speed word (generally a very verbose word) followed by tree number. In order to have short name, we made the following rules: Bridge-Aggregation -> Br FastEthernet -> Fa Forty-GigabitEthernet -> Fo FortyGigabitEthernet -> Fo GigabitEthernet -> Gi Giga -> Gi Port-Channel -> Po Ten-GigabitEthernet -> Te TenGigabitEthernet -> Te Ten -> Te All Klask command automatically normalize the port name on standart output and also on input command line. In the case of use an aggregator port (Po, Tk, Br ...), the real ports used are also return. =head1 FILES /etc/klask/klask.conf /var/lib/klask/klaskdb /var/lib/klask/switchdb =head1 SEE ALSO Net::SNMP, Net::Netmask, Net::CIDR::Lite, NetAddr::IP, YAML =over =item * L =item * L =back =head1 VERSION $Id: klask 246 2017-09-08 08:38:15Z g7moreau $ =head1 AUTHOR Written by Gabriel Moreau, Grenoble - France =head1 LICENSE AND COPYRIGHT GPL version 2 or later and Perl equivalent Copyright (C) 2005-2017 Gabriel Moreau.
