Attackers frequently use ACK scans to circumvent a firewall or other filtering tools. During a NULL scan, all packet flags are enabled. The most recent versions of Nessus Server and Client are compatible with Windows, Mac OS X, FreeBSD, and the vast majority of Linux variants.
<h3>What is ack scan ?</h3>
- ACK scans are used to identify hosts or ports that have been blocked or are resistant to other types of scanning. An attacker uses TCP ACK segments to learn about firewall or ACL configuration.
- Attackers probe our router or send unsolicited SYN, ACK, and FIN requests to specific UDP/TCP ports.
- TCP ACK Scan sends an ACK message to the target port to determine whether or not it is filtered.
- On unfiltered ports, a RST reply packet will be sent for both open and closed ports. Filtered ports will either generate no response or generate an ICMP reply packet with an unreachable destination.
- The TCP ACK scanning technique attempts to determine whether a port is filtered by using packets with the ACK flag set.

<span>Step 1Determine what type of connection you need for your computer and printer. If you see a large rectangular connection on your printer it is a parallel printer, and you will need to make sure you have a parallel port on your computer. This connection will be long and rectangular, and it may be red in color. If your Canon printer has a small square connection on the back it is a USB printer, and you will need to look for a flat slot on your computer to hook it up.Step 2Connect the printer and computer. If you are working with a parallel printer connect the large end of the cable to the back of the printer and the smaller end to the computer. If you have a USB printer, connect the square end of the cable to the back of the printer and the flat end to a free USB port on your computer.Step 3Turn on your printer and the computer. Insert the print cartridges that come with the printer. Watch the lower right-hand corner of your computer screen for a "found new hardware" message. This is your indication that the operating system has found your new printer and is installing the proper driver for it.Step 4Insert the CD that comes with your printer, if you are prompted to do so. If your operating system was unable to find a suitable driver it will prompt you for the CD. Keep your CD handy anyway, because you will need it to install the printer utilities.Step 5Insert the CD and allow it to install your printer utilities. After the utilities are installed you will be prompted to clean and align the print heads on your new printer. After the print heads have been aligned your new Canon printer will be ready for use.hope this helps</span>
