Add custom MAC range vendors

[mattheys]

Relating to #38

Can we have a config option to add a known range of MAC addresses to a vendor via Environment variable or something?

I would like all my Proxmox hosts that start BC:24:11 to show as Proxmox, however Proxmox also let's you define your own Mac prefix so this might not be the same for everyone, hence a configurable setting to be able to add an array of maps.

It would be nice to change all the (Unknown)'s into something I would recognise, especially in a test lab where you are spinning up stuff and destroying it quite a lot.

I think this is coming from an external tool but if it's possible to add in an override for these config options it would be really handy.

Thanks

I think I've found a solution

1. map a volume to /etc/arp-scan e.g. /docker_stacks/watchyourlan/_data/arp-scan:/etc/arp-scan
2. edit/create a file named mac-vendor.txt in the 'arp-scan' folder with vi or nano e.g. 'vi mac-vendor.txt'
3. add mac address vendor / vendor name (mac address needs to be all uppercase) and must be seperated by a tab e.g. 'BC2411 ProxmoxVE' and save
4. delete the old database from /data/WatchYourLAN and restart the docker container or manaully delete existing enteries one by one in the gui
5. you should now see the updated mac vendor details

well 'BC2411 ProxmoxVE' is already part of the standard ieee mapping
the ieee mapping is almost changing every days
either because a firm has changed a typo in their name of because of range owner ship has changed...

I created that script to directly update the default ieee-oui mapping used :
which allow me to get less unknown things.
issue is that once a device is known the mapping is not updated, I will need to check to code for this.
cat update.sh

wget -O /tmp/oui.csv  "http://standards-oui.ieee.org/oui/oui.csv"
wget -O /tmp/cid.csv "http://standards-oui.ieee.org/cid/cid.csv"
wget -O /tmp/iab.csv "http://standards-oui.ieee.org/iab/iab.csv"
wget -O /tmp/mam.csv "http://standards-oui.ieee.org/oui28/mam.csv"
wget -O /tmp/oui36.csv "http://standards-oui.ieee.org/oui36/oui36.csv"

>/usr/share/arp-scan/ieee-oui.txt
for file in iab.csv oui36.csv oui.csv cid.csv mam.csv
do
   #will not be complete for column which do include , into "strings"
   echo "#from $file" >>/usr/share/arp-scan/ieee-oui.txt
   cat /tmp/$file | grep -v Registry | awk -F ',' '{print $2 "\t" $3}' >>/usr/share/arp-scan/ieee-oui.txt 
done
