Question

i'm trying to open a pcap file but a get this error

I did deniel@ubuntu:~/Sites Ruby on Rails/helloWorld$ pcap_tools out.pcap

I got

im using this pcap_tools gem from https://github.com/bpaquet/pcap_tools

any idea please? Thanks

Answer 1

Works with rvmsudo pcap_tools out.pcap

Here is an explanation rvmsudo vs sudo?

Answer 2

sudo pcap_tools out.pcap

Sudo is short for

Sudo = Super user do command_name

Are you trying to sniff the internets?
