![]() ![]() ![]() You will need to examine this packet in raw form (expand the view in Wireshark), and make a note of the hex bytes in the "payload". This magic packet contains the root password in encrypted form in the packet padding at the end of the ARP. ![]() The last ARP in the series of ARP's will be a ping to an IPaddress whose last field is one greater than the previous pings. This label comes from the fact that the server modules used on Control Solutions IP products are made by Digi International, previously known as "Digiboard”.įollow the same process above, but look closer. Your device will have a MAC address that starts with 00:40:9D, also labeled with a source that starts with "Digiboar_”. (To make sure it is your device, connect only i.CanDoIt or Babel Buster and your PC to a switch while doing this exercise.) Now look for the ARP packets and note what IPaddress they came from. Wait until you are certain the device has booted up, or wait 2-3 minutes to be sure if you don't recognize the bootup LEDsequence. To recover the lost IPaddress, connect a PC withWireshark to the network, start Wireshark capturing packets, then power cycle the i.CanDoIt (or Babel Buster). If it finds another device with its own IPaddress, it will set its own IPaddress to a default pseudo-random address generally starting with 192. This is part of its duplicate address resolution mechanism. Upon power up, the device will ping its own IPaddress one or more times. But since you will need to power cycle the i.CanDoIt (or Babel Buster), you will need to have somebody local anyway. It depends on your network configuration. We say "must"because we don't guarantee it will work without being connected locally even though we don't guarantee it will fail either. You will need a network packet sniffer such as Wireshark (available at no cost at and must be locally connected to the i.CanDoIt (or Babel Buster, etc.) since the packets of interest will not pass through routers. ![]() How to recover forgotten IP address or root password using Wireshark - Print View How to recover forgotten IP address or root password using Wireshark ![]()
