System Administration 166 Getting Started Guide in.talkd: ALL in.ntalkd: ALL in.fingerd: ALL in.ftpd: ALL This configuration allows all connections from mycompany.com and *.mycom- pany.com machines. It also allows the services talk, finger, and ftp to accept requests from all machines. The tcpd program allows much more sophisticated access control, using a combi- nation of the files /etc/hosts.allow and /etc/hosts.deny. Read the tcpd(8) and hosts_access(5) man pages for complete details. KDE File Locations KDE is installed with OpenLinux by default and is available to all users on the system. The main KDE files are placed in the /opt/kde directory. The most important sec- tion of this directory is the share subdirectory. Its subdirectories include: • share/applnk Contains KDE Link files for applications that are included on the main menu. Subdirectories of this directory appear as submenus on the main menu. Each item in this directory and its subdirectories should be a valid KDE Link file. Items are displayed in the main menu in alpha- betical order. • share/apps Contains per-application configuration and temporary storage information. Subdirectories of this directory are created as needed by KDE applications. • share/mimelnk Contains MIME type definitions for all of KDE. Regular users cannot add to this directory. • share/config Contains the master configuration file for each KDE appli- cation that has been launched. Per-user configuration data is stored in the per-user configuration directory (see below). The configuration informa- tion stored in this directory for a given application applies to all users of the application unless overridden by the information in the user’s configu- ration directory (~/.kde/share/config). These configuration files generally contain default settings. If no configuration file is present in this subdirec- tory the application will use defaults internal to the application.
