('binary' encoding is not supported, stored as-is)   I'm actually doing some researches about switched
networks security, on cisco switches ( 2900, 2950XL... ). I
used some prgs of the dsniff suite like dsniff itself,
macof and arpspoof. My problem is that my attacks on these
switches have not succeeded using :
- macof : it didn't lead to anything. Dsniff didn't sniff
anything as i launched it during a telnet session on my
small local network between to win2000 pcs.
- arpspoof : as soon as i lauch arpspoof, the network is
almost out of service. I mean i can still ping pcs between
eachother, but the telnet sessions won't open. ( I ENABLED
THE IPFORWARDING OPTION ON MY LINUX COMPUTER, and it works
as the pings go through it ).

  Any ideas of the way of making it work ? I'm really
stucked and a presentation is scheduled for
tuesday !!! :o), so any ideas will be gratefully
appreciated :D.

              thx in advance....
