You probably find out find that your server is being attacked by brute force SSH attacks, port scanning, viruses scanning for the ability to spread, things like that or for some other reason  you want to block a specific IP on your server. In this article, I’ll show you how to block an IP address on Linux server using IPTables. First, I’ll assume you are already using iptables. You can check that using this command line: iptables -V Second, you have to create 2 shell script files in /etc/init.d folder.

Google has released on June 18 2013 Chrome version 27.0.1453.116 for Windows, Macintosh and Chrome Frame platforms that addresses a huge vulnerability issue with Flash Player. This issue is a specific type of clickjacking now known as camjacking, and it basically tricks users into pressing the “Allow” button in the Flash Player Settings window. This issue has been fixed by Adobe since October 2011, but somehow it could still be leveraged in Chrome to hijack web-cams and microphones. A proof-of-concept  (not safe for work) (Chrome only) was developed by security researcher Egor Homakov @homakov to explain this exploit. This issue was first reported by @typicalrabbit in a blog post on of which the translated version can be found here. The proof shows a slide-show of pictures with girls,[…]

Hey everybody, We got several requests these days regarding the messages that are automatically displayed in the chat. Some of you probably already know how to edit or disable the messages but we thought we should write a more comprehensive article about it. This feature was added in Build 1505 of AVChat 3 to give the website owner the ability to add info messages, text ads with links or any other announcements in the text chat. In detail The file which stores the messages is rotate_messages.php located in the AVChat 3 installation folder. It is called by AVChat 3 every rotatingMessageTime seconds (option in avc_settings.xml) and it sends to it a GET variable named count which stores the number of times it[…]

These days we faced some annoying spam attacks on our forum and had to take some security measures that will share with everybody here. As first quick measures: 1) You have to ensure that the registration page contains at least a “Questions and answers challenge” and a CAPTCHA code. For those who don’t know, this area can be found in the AdminCP under the menu System->System Settings->Security and Privacy. We used to have re-captcha from Google before, but the bots were still getting in, so we switched to “Are you human PlayThru” to see if something changes. Here’s a graphic of user registrations due the past months where we can notice abuse of users registered:         2)[…]

Ever wondered what users would appreciate on a SocialEngine website? Besides the obvious features found on SocialEngine PHP, the next best thing that we found after we’ve made a survey is that almost all of them would certainly appreciate a video chat application on a site they’re registered. And after installing our video chat plugin for their websites, owners said that users got more engaged and spent a lot more time on their site. Owners also said that at first, the users didn’t know about the extension and didn’t interact to much. So they had to make them aware of the full benefits of the video chat. here’s how they did it: Some of them hosted talk shows using the[…]

“I’d like to know if I can run other Red5 instances on my server, besides the one that AVChat requires.” This is an issue that came recently for some of our existing customers and I thought that we can share this info to everybody.   It happens that you have been using a software that requires Red5 to transmit data and you have installed, for example, Red5 0.9. Good.. Now, after you got an AVChat license, you heard that the only compatible versions of Red5 with the chat software are 0.8 and 1.0 RC1. This made you wonder if you can still use your previous software running on the same Red5 0.9 as before and make a different installation of[…]
