packet02-rewriting issue

[irenge]

Hi I follow the guideline but I still not get packet to rewrite is there any command I am missing I get this on one terminal t exec -- socat - 'udp6:[fc00:dead:cafe:1::1]:2000' [sudo] password for maxx:

and on the other this

t tcpdump dropped privs to tcpdump tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on veth-packets, link-type EN10MB (Ethernet), snapshot length 262144 bytes

It just stuck on that :(
