Get pdfExporting GIS Layers to AutoCADThis tutorial is intended to guide you through the process of exporting ArcView Shapefiles for use as vector files in AutoCAD.
1. Create a map in ArcMAP.
2. Click on the red ArcMAP toolbox in the toolbar at the top of the screen. This will open a window between the Table of Contents and the Map section of your screen.
3. Select Conversion Tools > To CAD > Export to CAD.
4. After selecting the Export to CAD feature, a dialog box will appear allowing you to select the features (shapefiles) that you would like to export by CAD. Select the layers you would like to export by selecting the layer name from the dropdown list that appears under Input Features.
5. Once your layers have been selected, select a destination file name and location.
PLEASE NOTE: ArcGIS 9.1 will NOT add the file extension to the file name you have chosen. In order to export your layers correctly, it is imperative that you add the ‘dwg’ extension to your file name.

You will be expected to implement an abstract protocol called Simple Registration Protocol using simple TCP socket programming. To illustrate the use of the protocol, you will also implement a concrete application: a simple appointment management system. This application will introduce you to the use of LAMP (Linux, Apache, MySQL and PHP), a free, powerful and commonly-used combination for Web-based applications.
The SRP uses a client-server model where multiple client processes request services from a server using request messages. These requests are answered using reply messages. The SRP includes only one mandatory request message (called REQ) and one mandatory reply message (REP). REQ is sent by a client to the server to indicate a specific application-defined service (e.g. reservation, confirmation, information request). The server responds with a REP message, the contents of which is specific to each type of request. The server should check the validity of each request and should not fail if an invalid request is received.
The client follows these three steps to make a request:
1. Establishes a TCP connection with the server,
2. Sends the request to the server, and
3. Closes the connection.
If the request is valid, the server
1. Opens a TCP connection to the client,
2. Sends the reply, and
3. Closes the connection.
Note that the REQ and REP messages are sent in two separate TCP sessions. The client will close the existing REQ TCP session and wait for the server to open a new TCP session for the REP.
Download pdfAn iptables guide & tutorialIptablesrocks was created to provide a publicly available, easy to understand guide and tutorial for the installation and configuration of iptables. Iptables is a linux package for managing IPv4 (and optionally IPv6) packet filtering and NAT (Network Address Translation). Iptables can be configured to function as a firewall, a NAT mechanism, a packet filter or all 3 at once. The diversity of capabilities possible with iptables makes it a secure, stable and economical alterative to hardware based firewalls and routers or costly 3rd party firewall software. Iptables can also serve as a rendundant firewall in conjunction with a hardware firewall, providing you with an extra layer of security. Iptablesrocks.org covers the installation of iptables in a Redhat environment, the syntax and structure associated with iptables and a collection a pre-configured iptables configurations for a variety of applications. This site is currently under development. Enjoy!
When running a typical web server, you need a firewall that is secure and offers protection, but you also need one that allows all needed traffic to be able to enter and leave the server so that your server's day to day operations can carry on unimpeded. This particular iptables configuration does the following:
1. Uses the "mangle" portion of the table to effectively block and/or confuse most port scans. These rules deal address FIN,SYN,RST,PSH,ACK,URG FIN,PSH and URG methods.
2. Establishes a locked down and secure foundation by initially blocking all incoming, outgoing and forwarded packets COMPLETELY.
3. With all incoming packets dropped by default, it then grants incoming accessUnreliable Guide To Hacking The Linux Kernel Tutorial ManualSome Basic Rules No memory protection If you corrupt memory, whether in user context or interrupt context, the whole machine will crash. Are you sure you cant do what you want in userspace? No floating point or MMX The FPU context is not saved; even in user context the FPU state probably wont correspond with the current process: you would mess with some user process FPU state. If you really want to do this, you would have to explicitly save/restore the full FPU state (and avoid context switches). It is generally a bad idea; use fixed point arithmetic first. A rigid stack limit The kernel stack is about 6K in 2.2 (for most architectures: its about 14K on the Alpha), and shared with interrupts so you cant use it all. Avoid deep recursion and huge local arrays on the stack (allocate them dynamically instead). The Linux kernel is portable Lets keep it that way.
Your code should be 64-bit clean, and endian-independent. You should also minimize CPU specific stuff, e.g. inline assembly should be cleanly encapsulated and minimized to ease porting. Generally it should be restricted to the architecture-dependent part of the kernel tree.

Get PDFMac OS X System Hardening Guidelines for Faculty and Staff DesktopsSystem security is important! If you ask the question, “Who would want to break into this system or why would they want to?,” the how and why of this line of questioning could fill volumes. The “who” could be anyone whether they have legitimate access or not. The “why” is simple: free computing resources, access to data, damaging your system, embarrsing the university. A compromised system can quickly become a liability as it can affect the network or operations on other machines both locally and remotely.
System security is a critical issue for the safety of your computer, the data on it, and possibly, the other computers on the network. This process of increasing system security is called system hardening. It is not a one-time event; it is a dynamic and reiterative process. Security holes are discovered daily in operating systems and programs. A secure system today may not be secure tomorrow. Some precautions taken now will save you from problems later.
There is no “magic bullet” for securing a system. Every aspect of the system and its maintenance must be considered when securing it. Securing in layers while adding granularity at each level is the best approach. For example, physical security is one layer. An example of adding granularity to physical security is to use badge access to the area where a machine is located. Host security could be considered at the top layer. An example of granularity at this layer is making sure all unnecessary Internet services are off. OneRenault Service Manual System PDFThe control module is central to the Entertainment system. It interprets and implements commands entered by the user using the system’s infrared remote control. These commands are relayed to the control module via the system’s infrared sensors mounted in the screen modules. It also distributes power to the system and detects the vehicle’s ignition state via a sense wire running from CN1 to the vehicle’s ignition switch. This enables it to limit battery drain whilst the vehicle is not in use. The control module receives audio and video inputs from the DVD Player via connector CN1 and from the vehicle’s TV tuner (if fitted) via connector CN2. It is also able to receive a further audio/video input and supply a low-level two-channel audio output via CN3.
Technical Description:
A micro-controller in the Control Module supplies and controls the power to the system via an I 2 C bus. On receipt of a power-on command from the Infrared Controller it performs a simple system check and then sends commands to other parts of the system to bring them on line. When a screen has been selected using the infrared remote control the Control Module identifies the selected screen and displays on it a menu providing the user with access to the functions detailed below: “Independent switching of three Audio-Visual inputs (DVD, TV and AUX) “Video manipulation (Colour, brightness, contrast and aspect ratio of the display.) “Audio processor (Bass, Treble and Volume) “On-Screen instructions language selection “Switch on/off individual screen displays The ControlRenault All Types Service Manual PDFInstrument panel with or without trip computer 83 ALL TYPES except N engine Adjust the various instrument panel functions (clock, etc…) if necessary.
