yes that's true
and another yes
it's possible

with the same package i uploaded (dsniff)
there is something called dnsspoof
it does the job
but i'll explain later because i don't have enough time now
and i'm honored to be in this community too

PS : dsniff package has those sniffing tools:
arpspoof dnsspoof dsniff filesnarf macof mailsnarf msgsnarf sshmitm sshow tcpkill tcpnice urlsnarf webmitm

ex : msgsnarf will allow you to sniff chat froma victim
and urlsnarf will get you the urls of the victim
and so on

and PS2: i still have many to do like airdrop-ng and hamster ,charon,mdk3,cowpatty ,driftnet
puff many work to do
short time i have
but i will be free after exactly 4 months(long time though) because of my stup*d bakaloriat
