Hardware Requirements for Installing FreeBSD 8.X Hardware Requirements1. Minimal ConfigurationThe minimal configuration to install FreeBSD varies with the FreeBSD version and the hardware architecture. A summary of this information is given in the following sections. Depending on the method chosen to install FreeBSD, a floppy drive, CDROM drive, or network adapter may be needed. Instructions on how to prepare the installation media can be found in Section 3.3.7, "Prepare the Boot Media". 1.1. FreeBSD/i386 and FreeBSD/pc98Both FreeBSD/i386 and FreeBSD/pc98 require a 486 or better processor, at least 24 MB of RAM, and at least 150 MB of free hard drive space for the most minimal installation. Note:In the case of older hardware, installing more RAM and more hard drive space is often more important than a faster processor. 1.2. FreeBSD/amd64There are two classes of processors capable of running FreeBSD/amd64. The first are AMD64 processors, including the AMD Athlon™64, AMD Athlon™64-FX, and AMD Opteron™ or better processors. The second class of processors includes those using the Intel® EM64T architecture. Examples of these processors include the Intel® Core™ 2 Duo, Quad, Extreme processor families, and the Intel® Xeon™ 3000, 5000, and 7000 sequences of processors. If the machine is based on an nVidia nForce3 Pro-150, the BIOS setup must be used to disable the IO APIC. If this option does not exist, disable ACPI instead as there are bugs in the Pro-150 chipset. 1.3. FreeBSD/sparc64To install FreeBSD/sparc64, use a supported platform (see Section 2, ??Supported Hardware??). A dedicated disk is needed for FreeBSD/sparc64 as it is not possible to share a disk with another operating system at this time. 2. Supported HardwareA list of supported hardware is provided with each FreeBSD release in the FreeBSD Hardware Notes. This document can usually be found in a file named HARDWARE.TXT, in the top-level directory of a CDROM or FTP distribution, or in sysinstall(8)'s docume
Network Appliance Security Systems and Tools (IPS) intrusion prevention system: An IPS, or intrusion prevention system is used in computer security. It provides policies and rules for network traffic along with an intrusion detection system for alerting system or network administrators to suspicious traffic, but allows the administrator to provide the action upon being alerted. Some compare an IPS to a combination of IDS and an application layer firewall for protection. (IDS) intrusion detection system: An intrusion detection system (IDS) inspects all inbound and outbound network activity and identifies suspicious patterns that may indicate a network or system attack from someone attempting to break into or compromise a system. An IDS evaluates a suspected intrusion once it has taken place and signals an alarm. An IDS also watches for attacks that originate from within a system. (VPN) virtual private network: A network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. firewall: A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. antivirus scanning: A utility that searches a hard disk for viruses and removes any that are found. Most antivirus include an auto-update feature that enables the program to download profiles of new viruses so that it can check for the new viruses as soon as they
LAN Bypass is a fault-tolerant feature that protects your essential business communications in the event of a power outage. When the power goes out, the WAN1 and LAN1 ports will be bridged together. When used with insert mode, such failures are completely transparent to the network. Therefore, your network connection is fully protected.Network Bypass in Networking: In the field of networking, "network bypass" can refer to a configuration in which traffic is rerouted around a network device or segment instead of being processed by it. This is typically used for high availability and performance. For example, a bypass switch can be used to route traffic around a firewall during maintenance without disruption.Network Bypass in Network Security: In the security world, "network bypass" can refer to techniques used by attackers to bypass security controls such as firewalls or intrusion detection systems. This can be achieved by exploiting vulnerabilities or misconfigurations in the network, or by using specialized tools to evade detection.Network Bypass in Telecommunications: In telecommunications, "network bypass" can refer to a situation where a customer routes a call through an alternate network instead of using the services of a traditional telecommunications carrier. This can be achieved by reducing costs or gaining more control over call routing.
