I am trying to query a list of hosts and extract all entries which 'dont' match.
Code:
SELECT LOGS.host, GOODLIST.host FROM LOGS,db.GOODLIST WHERE (LOGS.host <> GOODLIST.host)
When I use this query, it is very very slow. Matching the host with the GOODLIST.host works great and fast but when I use <> to get the hosts which DONT match, it doesnt work as expected. Am I using the wrong approach?
Hi there,

arpspoof
ARPSPOOF(8) System Manager's Manual ARPSPOOF(8)NAME
arpspoof - intercept packets on a switched LAN
SYNOPSIS
arpspoof [-i interface] [-c own|host|both] [-t target] [-r] host
DESCRIPTION
arpspoof redirects packets from a target host (or all hosts) on the LAN intended for another host on the LAN by forging ARP replies. This
is an extremely effective way of sniffing traffic on a switch.
Kernel IP forwarding (or a userland program which accomplishes the same, e.g. fragrouter(8)) must be turned on ahead of time.
OPTIONS -i interface
Specify the interface to use.
-c own|host|both
Specify which hardware address t use when restoring the arp configuration; while cleaning up, packets can be send with the own
address as well as with the address of the host. Sending packets with a fake hw address can disrupt connectivity with certain
switch/ap/bridge configurations, however it works more reliably than using the own address, which is the default way arpspoof cleans
up afterwards.
-t target
Specify a particular host to ARP poison (if not specified, all hosts on the LAN). Repeat to specify multiple hosts.
-r Poison both hosts (host and target) to capture traffic in both directions. (only valid in conjuntion with -t)
host Specify the host you wish to intercept packets for (usually the local gateway).
