Wise choice ..

An archaic method ..

Well u can't but I guess you do not have people who are technically
competent in your college..
At our office only admins are allowed to use (or for that fact know ) about
sniffers ..
We have SSH in place to safeguard against that .. however there are
antisniffers which figure out which systems are in promiscuous mode .. once
identified the guy is in trouble .. there are several methods and they are
quite simple to identifiy systems with sniffers .. I used sniffers about a
year or so down the line .. still use them only if we have n/w connectivity
issues .. I guess its all upto u and ur moral sense .. If you respect others
privacy sniffers are a no . no
U'll realize it all when somebody uses a sniffer and gets your password ..
U know when someone uses your account .. Ouch .. It hurts .. ;-)

Well install an antisniffer .. there are plenty of them .. had seen some for
NT ... would not encourage the spread of these tools so no URL's
