Wow, psnuffle!

[sempervictus]

Probably need the packet the caused this for a rational debug.

I also encountered this mistake

[Jheack]

[bcoles]

@Jheack do you have a packet capture? Which protocol? lldp ?

[ttskym]

@busterb all right , it has been a long time since i issued the problem...

version: metasploit v6.3.27-dev I encountered this mistake

[adfoster-r7]

@Emily201505 Are you able to consistently replicate this issue? We can't fix reliably fix this without knowing the protocol that caused the issue etc

[sempervictus]

@Emily201505 - any chance you could acquire the actual LLDP packet causing this into a pcap/base64/something we can use to reproduce? Quick glance at where thats happening kinda makes me wonder "how"

[Emily201505]

@sempervictus

[sempervictus]

Thanks for the screenshot, i was hoping for a pcap of the packet. However, that does at least show us where we need to add an exception handler - in this case, packetfu itself.

I have the same problem. How can I solve it ，in the metasploit framework ,use Auxiliary (sniffer/psnuffle) failed.
