WINBOX MAC SCAN

Tue Dec 12, 2006 2:36 am

I wonder how the scan option works,
If the routerboard don't got any ip you can scan for it and connect it using winbox.

How is that connection made?
I just want to see some specification about it.
I know its using its mac address but, how you can make a tcp connection using just the mac for destination.


Sorry for my english & Ty

Official docs:
http://www.mikrotik.com/docs/ros/2.9/ip/mndp

Mt is supposed to send mndp packets each 60 secons, but you can active poll it like neighborViewer does, according to wireshark:
Send UDP packet
localip:5678 -> 255.255.255.255:5678
Containing 8 bytes of data:
00 00 00 00 00 06 00 00
Response includes, among other unknown values:
 Mikrotik
 version
 system name
 soft-id
I could reproduce it:
echo 00 00 00 00 00 06 00 00 | xxd -r -ps | nc -w1 -nbvu 255.255.255.255 5678

Who did tell you that it is using TCP connection in MAC telnet mode? Try to use sniffer and you'll see yourself.

I talked about discovery, but "Mac telnet" is another story yes.

Btw, have you noticed that you can do mac telnet from winbox? Just type mac addy instead of ip addy. :wink:

if you sen in winbox to search for addresses, it fills in MAC addresses, and connects using mac-telnet.
