Computer threat - continued
2007-07-05 14:08:00 Another threat to the computer and network as follows:Denial of Service (DoS)This type entangling the hacker and or a certain party to send a number of ICMP echo request to the broadcast address. Remember that the address of sender request have been disguised so difficult to tracks.Protection to the network can be done by selection to the reciprocation of ICMP echo, another way is do not activate the directed broadcast at the router. Permit out package only and the sender address same with internal network address. This is important to the network securityThe other level of Denial of Service(DoS) is Distributed Denial of Service (DDoS).This type will increase the traffic and combine the bandwidth from some of host to one target host or network.SpoofingIs the creation of TCP/IP packets using somebody else's IP address. Routers use the "destination IP" address in order to forward packets through the Internet, but ignore the "source IP" address. That address is only used by the destin...

Computer Network Administrator must know below computer port and my previous posted about Computer Port List .What is TCP/UDP?TCP and UDP are transport protocols used for communication between computers.TCP:Abbreviation of Transmission Control Protocol, and pronounced as separate letters. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.UDP:Short for User Datagram Protocol, a connectionless protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network. Service Name UDP TCP ...

Computer Port list
2007-05-30 08:32:00 What is Computer port ?An interface on a computer to which you can connect a device. Personal computers have various types of ports. Internally, there are several ports for connecting disk drives, display screens, and keyboards.Externally, personal computers have ports for connecting modems, printers, mice, and other peripheral devices.Almost all personal computers come with a serial RS-232C port or RS-422 port for connecting a modem or mouse and a parallel port for connecting a printer.On PCs, the parallel port is a Centronics interface that uses a 25-pin connector. SCSI (Small Computer System Interface) ports support higher transmission speeds than do conventional ports and enable you to attach up to seven devices to the same port.In TCP/IP and UDP networks, an endpoint to a logical connection. The port number identifies what type of port it is.For Network administrator must know about the computer Port , to identify network attack and network function purposed.Below is a general c...

Callback connection setting
2007-05-26 05:20:00 The callback feature instructs your remote access server to disconnect, and then to call you back, after you dial in.What does it mean and what for ?Call the server from your home, then immediately hanging up by the server and then server dialing you back.Required callback enhances network security by ensuring that only users from specific locations can access the server. By dropping the call, and then calling back a moment later to the preassigned callback number, most impersonators can be thwarted.How it work ?You call the server to the server via modem, once your server modem response, your connection automatically disconnected then your server call you back.What for ?For example, you need some file from your network server while you are at home or you are out of office, and this is reduce your phone charge and the others one, you can used internet trough your server network as a gateway.How to Setting ?Office/Server Setting:step 1: Incoming Connect ion Open Network Connection -> C...

Network security - Firewall setting
2007-05-18 05:56:00 You probably know that you need firewall security; in fact, you may even already have a firewall management program in place. But what exactly is firewall security, and what does firewall management entail?The word firewall originally referred literally to a wall, which was constructed to halt the spread of a fire. In the world of computer firewall protection, a firewall refers to a network device which blocks certain kinds of network traffic, forming a barrier between a trusted and an untrusted network. It is analogous to a physical firewall in the sense that firewall security attempts to block the spread of computer attacks.How Does Firewall Management Work?A firewall management program can be configured one of two basic ways: * A default-deny policy. The firewall administrator lists the allowed network services, and everything else is denied. * A default-allow policy. The firewall administrator lists network services which are not allowed, and everything else is accepted.A ... More About: Security , Network Security , Network

Testing Audio card Quality using RMAA
2007-05-13 17:19:00 Microsoft suggested to installed audio component at PC for standard facility, In the middle of year 1990Now sound Card is included in the PC motherboard as responded to Microsoft suggestion. Many type and kind of sound card used on the PC motherboard at the moment, but sometimes PC consumer is not care about the quality of the sound.Four criteria to determine quality of sound card as below:1. Resolution2. Sampling rate3. Signal/noise ratio (SNR)4. Channel quantityThe explanation of sound criteria:1. ResolutionThis is a level of original sound compression.Resolution is higher, compression level make distantly spaced and the sound quality more high. Sound resolution about 16 bit, but some already 20 – 24 bit.2. Sampling rate:Conversion analog to digital by second value. Sampling standard value is 44.1Khz, almost sound card work with 48Khz and at the moment thru 192Khz.3. Signal to Noise Ratio (SNR)Major sound and minor sound differential result by sound card.

ROUTER Configuration (part: II)
2007-05-09 19:03:00 Static and Dynamic Router sFor routing between routers to work efficiently in an internetwork, routers must have knowledge of other network IDs or be configured with a default route. On large internetwork, the routing tables must be maintained so that the traffic always travels along optimal paths. How the routing tables are maintained defines the distinction between static and dynamic routing.Static RoutingA router with manually configured routing tables is known as a static router. A network administrator, with knowledge of the internetwork topology, manually builds and updates the routing table, programming all routes in the routing table. Static routers can work well for small internetworks but do not scale well to large or dynamically changing internetworks due to their manual administration.Static routers are not fault tolerant. The lifetime of a manually configured static route is infinite and, therefore, static routers do not sense and recover from downed routers or downed li... More About: Configuration , Part , Config
