This chapter deals with more advanced topics. Some sections are self-contained, but most are not. In order to better understand the concepts mentioned in this chapter, it is recommended that you read 'Concepts' first. Written by Marina Miler. ELF - Executable and Linking format A short introduction The executable and Linking format (ELF) specification is published by UNIX System Laboratories in the System V Application binary Interface(ABI). Characteristics and division Elf is very flexible, which means that it does not depands on a special processor or architecture, and exstensible, too.
The main types of object files are executable files, relocatable files and shared object files. Executable files are files containing a program that is apropriate for execution. Shared object files contain code and data adequate for linking in two possible ways. The spreading of ELF. Fedora 13...Automatic Login... Tools/NetworkManager. NetworkManager NetworkManager is the primary configuration service for Networking in Fedora. Most of the information you might be interested in are in the Networking page or its subpages. Desktops and laptops NetworkManager provides automatic network detection and configuration for the system.
Once enabled, the NetworkManager service also monitors the network interfaces, and may automatically switch to the best connection at any given time. These facilities are most useful for modern laptops, where the user may move between wireless networks, and plug in to a variety of wired networks, but NetworkManager also provides features that are relevant to workstations. NetworkManager requires Fedora to have drivers for the wired and wireless interfaces on the computer. Drivers firstNetworkManager may only work with network interfaces once the relevant drivers are correctly installed on your system. Servers Fedora now by default relies on NetworkManager for network configuration. Documentation Notes. Securing SSH — Fedora Unity Project. Common kernel problems. This page documents common problems with the Linux kernel in Fedora. How to set kernel boot options Kernel boot options are contained in the file /boot/grub/grub.conf.
Each installed kernel has a group of lines called a stanza describing: the title of the operative system to load where to find the boot partition (in grub named root!) What kernel (vmlinuz-*) to boot, with additional kernel options the name of the initrd to load A typical stanza looks something like this: In this example, we have three OO.SS: Fedora 13 (boot) resides on the eighth partition of the second hard disk. Kernel options are placed at the end of the kernel line and are separated by spaces. For other options view also the wiki Dracut kernel command line parameters.
When having problems, it is usually a good idea to remove the quiet option so that the full set of kernel messages is shown during boot Getting the Full List of Kernel Options How to set module options for boot drivers sata_nv.adma=0 options sata_nv adma=0. Communicating and getting help. Fedora has a strong community that is ready to help you. Because users and contributors span the globe, a key element to the project is communication. forums , mailing lists and IRC provide quick and easy ways to communicate.
Interacting with the Community Make sure that you understand and follow our guidelines before you start communicating with others in the Fedora community. Some basic guidelines can be found in the Mailing List Guidelines and the IRC How-To. Helping Yourself Before seeking help from others, please take a little time to review the huge variety of self-help resources that are available. Man yum Press q to quit. To read the info pages on gcc, you can use: info gcc There are a number of other documents available on your system under the documentation folder at /usr/share/doc/. Rpm -qd coreutils While these commands work from a terminal, other easy-to-use tools are also available.

From Techotopia Secure Shell (SSH) is a TCP/IP service that provides a secure mechanism for remotely logging into one system over either a local network or the internet into another system. SSH also provides the ability to transfer files between remote systems. When a user logs into a remote system using SSH, they receive a command prompt allowing them to enter commands on the remote system as if they were sitting at the remote system and had opened a terminal session. In this chapter we will cover the steps necessary to configure a Fedora Linux system to accept SSH connections.
This involves installing the SSH server on the local systems and configuring the firewall to allow SSH connections. [edit] Installing SSH on an Fedora Linux System In order for a system to accept SSH connections the system must first be running the SSH server. /sbin/service sshd status This will generate output similar to the following if the service is installed and running: sshd (pid 9488 9486 1850) is running...

This page contains information on Flash, a proprietary format for delivering audio and video content, primarily over the Internet.
Flash is non-free/proprietary software Adobe's Flash plugin cannot be included in Fedora because it is not free/libre and open source software. Adobe does release a version of the Flash plugin for Linux, and this can be used in Firefox, Konqueror and other popular Internet browsers. When Adobe releases a newer version of the Linux Flash plugin, it makes packages available for Fedora, but Fedora cannot include Adobe's plugin as long as it is unavailable as free and open source software. There are other open alternatives to Flash itself, including the patent unencumbered and free WebM, Ogg Theora video and Ogg Vorbis audio formats. YouTube and WebM support To enable support for it in YouTube, go to and click on "Join the HTML5 Beta" link in the bottom of that page. Flash plugin. Compiling 32bit on 64bit Fedora.
