How to Subnet a Network : Learn-Networking.com A properly designed subnet can do wonders for the security and performance of a network. The main idea in subnetting is to divide a network into smaller pieces, which we call subnets. Actually implementing a subnet is typically more difficult than simply using the default subnet mask of 255.255.255.0. This usually means that temporary or smaller networks do not need to be subnetted. Security sees benefit since the IP addresses of the host computers on each subnet are masked by the network address- which means they are invisible to the outside world. A Basic Review on Subnetting If you’re a little rusty on the basics of subnetting, don’t worry. The current version of internet protocol, or IP, is IP version 4. Each IP address is usually represented in decimal form, as seen above as “192.168.2.1”. The IP version 6 protocol was created for when the transition is needed. Classes There are three main types of classifications of IP addresses in IPv4: class A, class B, and class C. Subnet Masks

The Finger Test to Check the Doneness of Meat Print Photography Credit: Elise Bauer There are two basic methods to test for how done your meat is while you are cooking it—use a meat thermometer, or press on the meat with your fingertips. My mother has been trying to get me to test meat with my fingertips for years, and for years, being somewhat of a scaredy cat (won’t it burn my fingers?) Then my friend David showed me up. Now the point of this story is not to embarrass David (though that would be fun, if it were even possible) but to encourage you, if like me, you’ve been shying away from trying this approach. This is one of those things that gets easier with practice. MethodHide Photos Open the palm of your hand. Now gently press the tip of your pinky and your thumb together.

Setting up a reverse SSH tunnel Learn to forward a port on a remote machine to a local machine while initiating the SSH tunnel from the local machine. SSH is an extremely useful tool in that it allows you to do many things in a secure fashion that you might not otherwise be able to do. One of the things SSH allows you to do is to set up a reverse encrypted tunnel for data transfer. Typically, when you initiate an SSH tunnel, you forward a port on the local machine to a remote machine which can allow you to connect to an insecure service in a secure way, such as POP3 or IMAP. However, you can also do the reverse. This is useful if you have a service on the remote end that you want to have connected to something on the local machine, but you don't wish to open up your firewall or have SSH private keys stored on the remote machine. To set up the reverse tunnel, use: <code>$ ssh -nNT -R 1100:local.mydomain.com:1100 remote.mydomain.com</code>

IP Subnet Mask Quick Cheat Sheet | Ask The Admin Besides the fact that I am studying for another Microsoft test and staring at subnets all day long – I also get asked on a regular basis how many addresses can i get from a /24 subnet or what does 255.255.255.0 mean. Let me break it down for you real quick like: When you use 255.255.255.0 as your subnet you are limiting yourself to a network containing all the same ip’s except for the last number. Like 192.168.1.0 where the 0 changes. And using 255.255.0.0 Would limit you to the last two digits changing like 192.168.0.0 . Check out this IP Subnet Tool Calculator – MINT! _TheSubnettingAdmiN_

Popular Surveillance Cameras Open to Hackers, Researcher Says | Threat Level In a world where security cameras are nearly as ubiquitous as light fixtures, someone is always watching you. But the watcher might not always be who you think it is. Three of the most popular brands of closed-circuit surveillance cameras are sold with remote internet access enabled by default, and with weak password security — a classic recipe for security failure that could allow hackers to remotely tap into the video feeds, according to new research. The cameras, used by banks, retailers, hotels, hospitals and corporations, are often configured insecurely — thanks to these manufacturer default settings, according to researcher Justin Cacak, senior security engineer at Gotham Digital Science. As a result, he says, attackers can seize control of the systems to view live footage, archived footage or control the direction and zoom of cameras that are adjustable. “All the ones we found have remote access enabled by default,” Cacak says.
Any phonetic script can be learned in just a few hours If you liked my association technique mentioned below, you would also enjoy my tips on using imagination to memorize vocabulary, which are discussed in great detail with many other hacks in the Language Hacking Guide. See the most popular posts on the right below for other interesting topics. For those curious, this post discusses Thai, but the ideas can equally be applied to other phonetic scripts such as Japanese (but not as well for Chinese). Just one week into the challenge of reading/speaking Thai in 8 weeks (actually only about 5 hours total, since I’ve been quite busy since I arrived, but I’ve made time to learn on the skytrain/in restaurants/taxis etc.) and I’ve reached the first major milestone already. I can read Thai. The major thing still missing is tones, which admittedly are an extremely important part of this language that cannot be ignored and I will get to shortly (Edit: Done! It was actually way easier than I expected. From squiggly symbols to new letters า ท Challenges ร
Alchemy - Open Source AI Proxy List - Best working proxies here A proxy list is a well kept list of all stable forms of proxies available online that is known to the source hosting the list. More or less, a proxy list is an organized list to help you determine a working proxy for use in your browsing or application needs. So, that brings us to another question if you are not familiar with it - and that is, what is a proxy website? A proxy website allows a user to access blocked or limited websites that they may not can usually access. It also supplies a means of confidentiality to a web user. Proxy based websites permit you to place a URL of a website that you wish to visit in their search box, and takes you through their proxy server, rather than visiting the site directly yourself. Basically, a proxy is a work-around or bypass of sorts to direct website interaction online. One larger issue with most proxy services though is availability.
