A SpaceX launch with Starlink satellites was postponed again for "about a week," in order to update satellite software and "triple-check everything," Elon Musk's rocket company said. The Falcon 9 rocket and its satellite cargo were originally set to blast off from Cape Canaveral Air Force Station in Florida on Wednesday night, but the flight was postponed by Space X, citing excessive winds over... »

President Trump has signed an executive order that paves the way for the US government to ban technology sales from Chinese vendor Huawei and anyone else it views as a national security threat. The order authorizes the commerce secretary to block any transaction involving communication technologies built by companies controlled by a foreign adversary that puts US security at "unacceptable" risk... »

Security researchers have found a new security flaw in Intel chips. Dubbed Zombieload, the bug could allow hackers to gain access to sensitive and otherwise private data in what is described as a "Meltdown-type effect."A "zombie load" is a high amount of data that the processor cannot properly handle, which causes the processor to use elements of its microcode to prevent the whole PC crashing.... »

Windows Vista introduces a number of new features to the TCP/IP stack, including CTCP, and TCP Window Auto-Tuning. This new implementation works much better by default than previous Windows versions with broadband internet connections, and is able to adjust the RWIN value on the fly, depending on the BDP (bandwidth-delay product). This, however, introduces some problems with older routers and restricts the user from tweaking some of the TCP/IP parameters. Still, there is always some room for... »

Introduction With the popularity of wireless networks and mobile computing, an overall understanding of common security issues has become not only relevant, but very necessary for both home/SOHO users and IT professionals alike. This article is aimed at illustrating current security flaws in WEP/WPA/WPA2. Successfully cracking a wireless network assumes some basic familiarity with networking principles and terminology, as well as working with command-line tools. A basic familiarity... »

I've often found it useful to get just the wireless functionality out of a WiFi router and reuse it as an access point. Wireless routers seem more common, and are often priced even lower than wireless access points. Adding an access point to a wired network already in place, or to one where the main NAT router is provided by the ISP is usually the easiest solution. However, introducing a second NAT router on the network is not a good idea, especially without some tweaking to set it... »

The Windows 8 TCP/IP implementation shares many traits with earlier Windows versions, however, there are some subtle differences, new syntax for applying tweaks, and some new settings. Windows 8 generally works well by default for many broadband connections, yet there is always some room for improvement and we will try to cover all relevant settings and their effect on your connection in detail below.To run some of the outlined commands, you will need to use an administrator account. With... »

Denial of Service (DoS) attacks are very common on the Internet these days, and they can make your online experience miserable. In some cases of Distributed Denial of Service Attacks (DDoS), they can bring down websites, or cripple entire networks in a matter of minutes, preventing connectivity for many customers. There are different types of DoS attacks, and we've tried to explain the most common types and ways to mitigate their effects to you or your network.Types of Denial of Service (DoS)... »

Online Gaming can often benefit from some fine-tuning of Windows TCP/IP settings and the Network Adapter properties. This article is intended to supplement our general broadband tweaks and list only TCP/IP settings that are specific to online gaming and reducing network latency. Some of these settings are also mentioned in our general tweaking articles, however, the emphasis here is on latency rather than throughput, and we have complemented the tweaks with more gaming-specific recommendations... »

To change TCP/IP related settings in Android you need root access. The only exception are a couple of trivial changes that are available to non-rooted devices, namely dynamic vs static IP address, and changing the DNS server. Assuming you are working with an already rooted device, the settings are listed below:Android TCP/IP tweaks (root required)In order to change other TCP/IP stack settings, you need to edit the settings in /proc/sys/net/core/ , similar to what is explained in our Linux... »

Microsoft enforces a limit on half-open TCP/IP connections that is hard-coded in tcpip.sys. The maximum simultaneous half-open (incomplete) outbound TCP connection attempts per second that the system can make is intended to limit the spread of malicious viruses and worms, as well as limit the possibility of launching a DDoS attack. However, it has proven to also limit some applications using many TCP connections, such as P2P and P2PTV programs.When the OS reaches the half-open connection limit,... »
