Photoshop CC has just been updated recently, adding Blur gallery movement effects, selected focus areas, color-mixed content recognition features, and so on. After this update, the Photoshop CC 2014 feature will be more powerful and more efficient. We've talked to you about the new Photoshop cc 2014 feature, and here's how to do this by creating your own 3D luts
The reason for the CC attack is that the dynamic page is constantly refreshed, such as the page for reading and writing databases from php + mysql. if the page is refreshed quickly, the page may be stuck or the server resource usage exceeds the limit, as a result, the server crashes. The following describes some examples to prevent CC attacks .... the reason for the CC
You shoshould always make sure you e-mail the right people, in the right way. the to, CC and BCC fields allow you to indicate how your message shocould be read by the people that receive it.

It's also a good idea to include all the people you put in the to: Field in your opener line.
CC Attack principle
CC is primarily used to attack pages. We all have such experience, that is, when visiting the forum, if this forum is relatively large, more people visit, open the page will be slower, right?! Generally speaking, the more people visit, the more The forum page, the larger the database, the frequency of access is also higher, the system resources occupied is quite considerable, now know wh
Adobe has released a new Creative Cloud series of creative software. As expected, the next generation of software more emphasis on interoperability between different components, and at the Taiwan Adobe MAX User meeting this week, from Adobe's creative solutions professional lecturer Paul Burnett dedicated to the CC series in the web design work of the new features.

This method is used to passively count the number of IP connections. iptables is used to block IP addresses with a large number of connections. For more information, see iptables to limit the number of ip connections to prevent CC attacks.The Shell script is as follows:#! /Bin/bash# Created by http://www.bkjia.comNum = 100 # Upper LimitList = 'netstat-an | grep ^ tcp. *: 80 | egrep-v 'Listen | 127.0.0.1 '| awk-F "[] + | [:] "'{print $6}' | sort | uniq

The following is a method for detecting disconnections in GetDlgItemText.

(Akira total) write an iptables rule3est: I thought it was good. I just reprinted it./* It is also a simple anti-CC attack.

The following methods to prevent CC attacks are mainly used to filter access logs and seal the IP address into the firewall. Place the script in cron once every 10 minutes. You can also modify the script as needed, because I use lighttp as a web server, it reads lighttp access logs. This script is also applicable to apache servers:#! /Bin/bash/Www/MTCC/solution_ip.sh/Usr/bin/tail-1000/var/log/lighttpd/access. log | grep-v 127.0.0.1 | awk {print $1} |
