How to send gratitious arp to upstream Fritzbox

Wed Apr 21, 2021 10:07 am

Hi, when going through the wiki , i see that i can use the traffic generator to send gratitious arp towards an upstream device (which might solve my other issue)
But the manual/wiki is a bit light, how to generate the raw data needed, which format is the ip and mac represented in the string, etc...

would be cool if someone could give me a hint/ solution


thanks

Do you mean what is shown at the bottom of this link:

https://wiki.mikrotik.com/wiki/Manual:IP/ARP

The MAC and IP addresses are just in hexadecimal format; nothing clever. The MAC is as usual, just without the colons/dashes. To convert the IP from dotted notation, just convert each octet into hex and do not miss off any leading zero. The IP address in the example on that link is 0a 05 7a 01 = 10.5.122.1 (I added the spaces in the hex to highlight the octets)
