Access Network When Everything Else is Blocked Using ptunnel 2008-01-16 06:47:55 Ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packets, commonly known as ping requests and replies. At first glance, this might seem like a rather useless thing to do, but it can actually come in handy in some cases. The following example illustrates the main motivation in creating ptunnel: Setting: You’re on the go, and stumble across an open wireless network. The network gives you an IP address, but won’t let you send TCP or UDP packets out to the rest of the internet, for instance to check your mail. What to do? By chance, you discover that the network will allow you to ping any computer on the rest of the internet. With ptunnel, you can utilize this feature to check your mail, or do other things that require TCP. Ptunnel Features Ptunnel is not a feature-rich tool by any means, but it does what it advertises. So here is what it can do: Tunnel TCP using ICMP echo request and reply packets ...

FTP Server setup with TLS (Transport Layer Security) on Debian 2008-01-02 02:36:57 ProFTPD is a ftp server written for use on Unix and Unix-a-like operating systems, there is no support for native use under Microsoft Windows. The TLS protocol allows applications to communicate across a network in a way designed to prevent eavesdropping, tampering, and message forgery. TLS provides endpoint authentication and communications privacy over the Internet using cryptography. Typically, only the server is authenticated (i.e., its identity is ensured) while the client remains unauthenticated. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure. This article explains how to set up ProFTPd with TLS on a Debian Etch server. Install ProFTPd And OpenSSL #apt-get install proftpd openssl You will be asked a question: Run proftpd from inetd or standalone? ...

How to configure webcam in Debian Linux 2007-12-04 08:58:20 The friend of mine had been presented to me a webcam recently. On the box of Logitech QuickCam, there were logo of an alternative operation system, but in Debian configuration of a webcam is as easy as 1-2-3. Here are tips for configuration of a webcam. Preparing Some preparing words - if you didn’t compile your own kernel, this section can be omitted. Webcam interface in kernel is almost like TV tuner - it is ordinary video device with /dev/video0 output. That`s why all articles about TV tuner configuration can help you as well. So, in kernel must be turned on: v4l and all of it protocols (v4l monolithically, protocols - as modules) i2c and it protocols (as well as during TV tuner configuration) If it is enabled in kernel, you shouldn’t get any problems. Installation In the camera`s box was wrote: installation as simple as 1-2-3. So, I get pretty the same: 1. Installing software.
