you can use tcpdump to see if (and who) you are querying for your name

I'm trying to learn a bit here and although name res is working on my box
have done an apt-get install tcpdump but when trying this get:
UNCLELEO:/home/marty# tcpdump -tqn dst port 53
tcpdump: getifaddrs: Connection refused
UNCLELEO:/home/marty# tcpdump -tqn dst port 80
tcpdump: getifaddrs: Connection refused
UNCLELEO:/home/marty#
Not sure if this might've been caused by a problem noted during the install
process:
UNCLELEO:/home/marty# find / -name tcpdump
UNCLELEO:/home/marty# apt-get install tcpdump
