ettercap - sniffing works, but I can't see passwords
I know that the ettercap forums would be a better place for this, but it looks like they have a problem when with the registration of new users, thats why I post it here...
I use the ettercap version of BackTrack 2.0 to perform some ftp password sniffing in a my switched lab. I used the arp spoofing feature in ettercap, that works, but I can't see any passwords in ettercap :(
I used tcpdump and wireshark to verify that the arp spoofing works correct and I can see all the packets (in wireshark I can see the username and password of the ftp session). But the password collectors in ettercap don't work.
Has anyone a clue what I'm doing wrong ??
