Command-Line Flags The following table shows the command-line flag options and explanations. Loads triggers i. Uses the dsniff.

Writes sniffed data to a file in Berkeley DB format for later analysis using dsniff -r. Usage and Output The only other argument that dsniff can use is a tcpdump packet-filter expression so that you can specify what kind of traffic you want to sniff for passwords. But what about the telnet session below it?

Dsniff appears to have captured an attempted root login via telnet. The login seems to have been unsuccessful, because it appears the user then tried logging in as jdoe with the password password and got into the system. Dsniff then recorded the ls command being executed. The password guessme could very well be the root password. Had jdoe attempted an su to root later in the connection, dsniff would have caught that, too.

Filesnarf Tcpdump can be used to sniff NFS traffic. The filesnarf tool can actually take the sniffed file and reassemble it on your system. Again, you can use the —i option to specify the network interface. If you want to snarf all files except certain files say, you want to snarf everything except MP3 files , you can invert the file pattern matching with —v like so:.

Macof The macof tool will flood the local network with random, conjured MAC addresses in the hopes of causing a switch to fail and start acting like a hub, allowing dsniff to have more success in a switched network environment.

You can control the network interface used -i , the source and destination IP address -s and -d , the source and destination port -x and -y , a single target hardware address -e , and the number of made-up packets to send -n. It saves the messages in standard mbox format so that you can browse them as you would any Unix mailbox using mutt, pine, or whatever Unix mail application you choose see Chapter The options are exactly the same as filesnarf, except instead of specifying file pattern matching, you specify regular expressions to be matched in the header or body of the message.

In this case, you can specify a regular expression pattern to search for in the messages such as saving only messages that contain the word password in them. My password is iLuvVeggies. You can use them for as long as you want. Sshmitm Sshmitm is one of the nastier tools that comes with dsniff. It supports only SSH version 1 a good reason to upgrade to version 2.

How is this done? Reporting such occurrences is your duty and you can get blamed and be fired and even prosecuted for not having done such. I did that today and he claimed he had done it for administration purposes; management didn't do anything. So now I'm just going to find a new job. Thanks for the suggestions.
