Automagically create a /etc/hosts file based on your DHCP list (only works on Linksys WRT54G router)

curl -s -u $username:$password http://192.168.1.1/DHCPTable.htm | grep '<td>.* </td>' | sed 's|\t<td>\(.*\) </td>\r|\1|' | tr '\n' ';' | sed 's/\([^;]*\);\([^;]*\);/\2\t\1\n/g'
Will create a sample etc host file based on your router's dhcp list. Now I know this won't work on most routers, so please don't downvote it just because it doesn't work for you.
