Reverse IP Lookup - Find Other Web Sites Hosted on a Web Server Find other sites hosted on a web server by entering a domain or IP address above. Note: For those of you interested, as of May 2014, my database has grown to over 100 million domain names. I am now offering this domain list for purchase. A reverse IP domain check takes a domain name or IP address pointing to a web server and searches for other sites known to be hosted on that same web server. Background All web sites are hosted on web servers, which are computers running specialized software that distribute web content as requested. As of 2003, more than 87% of all active domains names were found to share their IP addresses (i.e. their web servers) with one or more additional domains. While IP sharing is typically transparent to ordinary users, it may cause complications for both search engine optimization and web site filtering. Concerning SEO (search engine optimization) Conversely, search engines value links from web sites hosted on different IP addresses. Concerning web site filtering
Using SSH Tunnel with PuTTY to browse internet hiding your IP address Thursday, December 11th, 2008 If you have access to SSH on a remote server (dedicated server, vps or shell account), you can browse the internet over the IP address hiding your original IP address. This can be useful for many scenarios like - IP based authentication over dynamic IP: In many cases for security reasons we use restrict access only to some selected IP addresses. Technical limitations related to shared/dynamic IP: In many places (specially in Bangladesh) ISPs provide the clients only with dynamic or shared IP address. Being a cool geek: Or you can use it just to surprise your friends (who actaully checks for your ip =P) by showing your domain on you email and forum posts ;) Anyways… enough of possible “usage”. Now to get straight into the tutorial. What you need? Now, first run PuTTY. Then, in the left-hand menu, click on “SSH“. Now expand the “SSH” menu and select the “Tunnels” sub-menu. Congrats! From now on you can use this connection to login to your server. Done!

CaptivePortalBypassHowto - Personal Telco Project As described in CaptivePortalInsecurities, you can bypass a captive portal by tunneling IP over UDP/53 which almost always is open. This page will give you step-by-step instructions on how to do this using OpenVPN. First, some assumptions: You want to use 10.11.254.0/24 as your "tunnel network" Your server runs some sort of sane *nix variant and is accessible from the internet and isn't using UDP/53 for something else Your client has the "ip route" command You know how to get openvpn mostly working (I'm not going to walk you through creating certificates, for instance) The captive portal you are bypassing has UDP/53 open (check by doing: $ dig google.com @4.2.2.2) OpenVPN Server You need a *nix box somewhere that is internet accessible and is running OpenVPN. You'll need to make the tap0 interface. auto tap0 iface tap0 inet static address 10.11.254.1 netmask 255.255.255.0 broadcast 10.11.254.255 network 10.11.254.0 /etc/openvpn/server.conf /etc/openvpn/route.up OpenVPN Client $ ip route Fix Me
How to Blog Safely (About Work or Anything Else) Published April 6, 2005 Updated May 31, 2005 Blogs are like personal telephone calls crossed with newspapers. They're the perfect tool for sharing your favorite chocolate mousse recipe with friends--or for upholding the basic tenets of democracy by letting the public know that a corrupt government official has been paying off your boss. If you blog, there are no guarantees you'll attract a readership of thousands. The point is that anyone can eventually find your blog if your real identity is tied to it in some way. Here we offer a few simple precautions to help you maintain control of your personal privacy so that you can express yourself without facing unjust retaliation. Blog Anonymously The best way to blog and still preserve some privacy is to do it anonymously. Let's say you want to start a blog about your terrible work environment but you don't want to risk your boss or colleagues discovering that you're writing about them. 1. 2. 3. 4. 5. 6.

Digital Identity, Privacy, and the Internet's Missing Identity Layer The third party commissioned by Google to review the software used in its Street View WiFi cars has completed its report, called Source Code Analysis of ‘Gstumbler’. I will resist commenting on the name, since Google did the right thing in publishing the report: there will no longer be any ambiguity about what was being collected. As we have discussed over the last week, two issues are of importance – collection of device identity data, and collection of payload data. “Each packet is comprised of a packet header which contains network administrative information and the addressing information (or “envelope” information) necessary to transmit the data packet from one device to another along the path to its final destination. It explains that in 802.11 packets are encapsulated in frames, describes the types of frames and presents the standard diagram showing how a frame is structured. In paragraph 19, the report provides an overview of its findings: All device identifiers were recorded
