Malformed packet when parsing dhcp ack

Open chirayu-patel opened this issue 3 years ago • 4 comments

Most of the dhcp acks in this packet capture are getting categorized as malformed.

E.g : 192.168.1.172, 192.168.1.166, 192.168.1.159

Can you please let me know the possible reason.

Looks like there's some padding at the end of around half of the packets, and those are not being parsed correctly. I'm not sure where this padding is coming from, but I'll try to have a look once I have some time.
