I noticed that when I type
sudo SomeCommand it hangs for a little. I started trying to figure out what was going on found one very strange thing:
when I type
tcpdump -i wlan0 and then do
sudo, I get this:
IP Jebediah-PC.35662 > gateway.domain: 58284+ A? Jebediah-PC. IP Jebediah-PC.35662 > gateway.domain: 62298+ AAAA? Jebediah-PC. IP Jebediah-PC.45253 > gateway.domain: 22831+ PTR? 22.214.171.124.in-addr.arpa. IP gateway.domain > Jebediah-PC.35662: 58284 NXDomain 0/1/0 IP gateway.domain > Jebediah-PC.35662: 62298 NXDomain 0/1/0 IP gateway.domain > Jebediah-PC.45253: 22831 NXDomain 0/1/0 IP Jebediah-PC.44842 > gateway.domain: 33078+ PTR? 126.96.36.199.in-addr.arpa.
It looks like some sort of DNS lookup. Here is a wireshark screenshot:
