Local Area Network

The Tribe Flood Network or TFN is a set of computer programs to conduct various DDoS attacks such as ICMP flood, SYN flood, UDP flood and Smurf attack.

Tribal Flood Network (TFN), like trinoo, is a classic DDoS attack, using a master program and multiple agents on multiple compromised systems.

Unlike trinoo it can spoof the source IP for the agents, and can generate multiple types of attack (including UDP flood, TCP SYN flood, ICMP echo request flood, and ICMP directed broadcast).

TFN2K is a more sophisticated version of the original TFN.

An open architecture in computers/technology is one in which the details are published and are known. Anyone can contribute to the technology because it has been well described.

A closed architecture is the opposite. Sometimes we call these proprietary architectures because little is know about them except by the creators, and they aren't telling ...

Redundancy in computer networks has to do with the back up systems that have been designed to avoid loss of information should a server, or shared network, go down. Often this includes scheduled backup "saves" onto a set of disks that are rotated daily, weekly, or monthly. This enables companies to repair the issue and reload yesterday's work (for example) and not have to do the work again.

that would be a managed switch which you can then create vlans within the switch

you would also need a router if all the segments would be on a different network

If you are asking about IPX/SPX Novell protocol, you uninstall the protocol attached to the network device (NIC) by going to the Network settings, finding the adaptor, and removing the protocol.

It is usually done by whatever program holds the address information. It can also be done through mail merge in some word processing programs.

The IP address and the subnet mask are required in layer 3 for routing purposes.

Assuming IP version 4 (the current standard), a complete IP address has 32 bits. /16 means that the first 16 bits specify the network; the remaining bits (also 16 in this case - calculated as 32 minus 16) specify the host.

Yes it is possible. Everything you send or transmit over a local network could potentially be viewed on another computer on that same network. You are able to download and install network sniffers such are WireShark and this will analyse the data being sent over the local network. You would need some basic knowledge of networks to interpret the data you are seeing but if there are only 2 computers on the network this is quite simple.

If the transmitions are encrypted for example if you are making a payment on a secure website this should be safe and details such are your card number would not be possible to get.

Reset the connection to automatic or the correct setting (if known).

From an application/service perspective the message payload is a combination of the Body and Attachments.

If they are both Windows computers, and they are connected to the internet, then they may not see each other unless they are part of the same Workgroup or Domain. Your computer is assigned an IP address by your router when it starts up. Domains are only used at businesses and other organizations with many computers, Workgroups are used on small LANs without a domain controller. In either case, you only need the Names of the computers for them to connect to each other, and you can browse for other devices in the same Workgroup or Domain. They both run the TCP-IP networking protocol, and they both use DNS to find other computers on the internet. The MAC address is a unique number of every network device and is the fundamental way they all communicate with each other. It is like your MAC (physical) address compares to your IP Address (e.g. a phone number), but you don't need to worry about it as it is automatically configured for you.

You have to explain the situation a bit more. Are you on a workgroup or a domain? Is it the computer cant get on, or is it the user cant get on? Are you sure that your computer can 'see' the network? Are there any error messages? What OS is on the computer? Was it previously getting on, or is it a new computer?

no we use the computer for home use but u cant login to anything and the computer wont pull up hardly anything it says something about the fire wall we don't know what to do about this

SMTP (Simple Mail Transfer Protocol) is assigned to port 25.

That shouldn't cause any problem, other than increasing the number of collisions on the segment of the domain that is on the hub, which slows down the network for those computers (especially if they are both being used at once). -DJ Craig

1. The latency between client and server can tackled by the following ways:

   1. we can break the client code for smaller request and replies. So when a part of data is received by the client, it can start working on that till the next part comes.

   2. client can run multiple sessions with server and data obtained can be added at the client end.

   3. the client can use the time between request and reply for other processes.

No- A VLAN is a single broadcast domain. If the VLAN uses a hub, which essentially connects all devices on a single wire, the the VlAN would be a collision domain. However hubs are rarely seen these days. A network switch keeps every device separated on individual collision domains so every device is kept from colliding with any other device.

You don't need to worry about changing any of the octets when the values of an octet contain leading zeros. The two examples are effectively the same.

You need at least two devices connected by some type of media to create a LAN. Most LANs would have a distance limitation of not more than 100 meters apart. Other than that, the computer could be placed anywhere within that distance to the other device to create the LAN.
