Klask Tool for mapping the local network - site ${SITE_NAME} ${LOCALTIME}

List of all IP addresses detected on the local network (on all VLANs) since the origin of the database (except those that have been deleted manually and voluntarily).

END klask exportdb --format html >> ${TMP}/index.html cat <> ${TMP}/index.html

List all free IP addresses (which have never been used or not used for two years). These IP addresses are available to assign to all new computers.

END klask ip-free --format html >> ${TMP}/index.html cat <> ${TMP}/index.html

List all computers connected to switches where the VLAN is misconfigured. Returns the port and VLAN to configure on these switches.

END klask bad-vlan-id --format html >> ${TMP}/index.html cat <> ${TMP}/index.html

Direct link to local network map in the formats png and svg. Because the map could be big, you will have a better web experience with Image Zoom plugin (or equivalent) installed.

The main raw results of Klask are accessible directly, via wget or curl tools for example, for any specific treatment:

Computers DB (command klask exportdb --format txt),
Switches DB (command klask exportsw --format txt),
IP available (command klask ip-free --format txt),
VLAN mismatch (command klask bad-vlan-id --format txt),
Map format: dot source (graphviz), png, svg.
