Wireshark · Wireshark-users: [Wireshark-users] Ping Replys without Request

["STEINECKE Michael SD-G (AREVA NP GmbH)" <Michael.Steinecke@xxxxxxxxx>]

Hello folks,

i've a bit strange issue in the communication between a Server and his
client (a microcontroler).
The controler send "Echo Reply" packets without a corresponding  ICMP 
requests. Is there another way how this can happen then an program or 
firmware error? Something like an TCP packet that requests a ICMP Echo
par example?

Best Regards
