An ARP attack can damage a network, so it is important to detect it early. Monitoring network traffic and utilization can help identify if the network is busy, normal, or idle, and if there are any abnormal activities like an ARP attack. If the network is slow, finding the top local hosts using bandwidth can reveal potential problems. Tracking down heavy bittorrent usage can also restore normal network conditions if it is consuming large amounts of bandwidth.

Network Protocol Analyzer
A packet sniffer, also known as a network monitor or network analyzer, is software that can capture and analyze all network traffic passing through a computer network interface. It works by operating a network interface in promiscuous mode to capture all traffic, including packets not intended for that interface. Packet sniffers are useful for network administrators to identify issues like wrong packets, delays, and rogue sniffers, but they can only capture traffic within their local subnet unless placed on a computer inside the target network.

Packet sniffers
This document discusses packet sniffing and methods for detecting packet sniffers. It defines packet sniffing as monitoring all network packets and describes common packet sniffer tools like tcpdump. It explains that packet sniffers can be used for both legitimate and malicious purposes, such as password theft or network mapping. The document outlines two key methods for detecting packet sniffers - MAC detection and DNS detection. MAC detection works by sending packets with invalid MAC addresses and checking if any hosts respond in promiscuous mode. DNS detection exploits the behavior of sniffers performing DNS lookups on spoofed source IP addresses. Both methods were found to accurately detect the presence of packet sniffers on a network.
Packet Sniffing
A packet sniffer is a program that intercepts and monitors network traffic by capturing packets in promiscuous mode. There are two main network environments where a sniffer can operate: a shared Ethernet and a switched Ethernet. In a shared Ethernet, all systems are connected to the same bus and broadcast domain, allowing a sniffer to easily capture all traffic. In a switched Ethernet, packets are specifically sent to intended machines, but a sniffer can still operate using techniques like ARP spoofing to intercept traffic. Common sniffer programs include Ethereal, Tcpdump, and Ettercap, while AntiSniff and ARP Watch can detect sniffing activities on a network.
Packet sniffing in LAN
This document discusses packet sniffing and ARP poisoning on a local area network (LAN). It begins by explaining that packet sniffing involves monitoring all network packets and putting the network card into promiscuous mode. It then discusses how ARP works to convert IP addresses to MAC addresses and maintains an ARP cache. The document goes on to explain how ARP poisoning, a type of attack, works by sending falsified ARP messages to associate the attacker's MAC address with a legitimate IP address, allowing the attacker to intercept network traffic. It provides an example of using the tool Cain and Abel to conduct ARP poisoning on a sample LAN to sniff usernames and passwords entered on a website.
Packet sniffing in switched LANs
This document discusses packet sniffing and ways to detect and prevent it. Packet sniffing involves using a packet sniffer tool to analyze network traffic. While switches make sniffing more difficult than hubs by only sending packets to their intended recipients, there are still sniffing attacks possible like ARP spoofing.

Packet capture in network security
Packet capture is an important topic in network security. Packet capturing and analysing tools are explained.
Ethical Hacking - sniffing
Packet sniffing tools like Ethereal and Snort can be used to intercept network traffic for diagnostic or malicious purposes. Sniffing tools capture packets in either command line or GUI format and some can reassemble packets into original data like emails. Sniffing can reveal usernames, passwords, and other confidential information unless encryption is used. Common sniffing techniques include passive sniffing using hubs, active sniffing using ARP spoofing on switches, and MAC flooding to force switch traffic to a sniffer. Encryption renders captured data useless, while detection tools can find machines in promiscuous sniffing mode.
Password sniffing
Password sniffing refers to the use of password sniffing programs or software that monitor network traffic to capture and record usernames and passwords as users login to networks. These programs listen to data packets passing through a network and record any instances of passwords being transmitted. Attackers can then use the captured login credentials to impersonate authorized users and access restricted information. To prevent password sniffing, users should avoid sending sensitive information over public networks and be aware that passwords could be at risk of interception.
Sniffing via dsniff
Sniffing is a technique used to capture network traffic for the purposes of hacking or troubleshooting. A sniffer program collects all data passing through a network interface. In passive sniffing on a hub, all data is broadcast to all devices. Active sniffing on a switch requires tricks like MAC flooding or ARP spoofing to redirect traffic. The Dsniff toolset includes programs for sniffing protocols like HTTP, HTTPS, SSH, and DNS. It can reveal passwords and spoof sites. Defenses include using encrypted protocols and static ARP tables, and paying attention to browser/client warnings.

Overlay networks
Overlay networks are virtual networks built on top of existing networks that add additional layers of indirection. There are several types of overlay networks including caching, routing, and security overlays. Two examples of anonymous communication networks are ACN and I2P. I2P uses "garlic routing" which involves layered encryption, bundling multiple messages together, and ElGamal/AES encryption. It has a distributed, self-organizing design and uses short-lived, unidirectional tunnels to provide anonymity through its network.
Xtc Pdiscussionv2
MainlineNet Holdings owns Extreme TCP, a new technology that improves upon the standard TCP congestion avoidance algorithm used on the internet. Extreme TCP uses complex router and network models to transmit data at higher speeds while avoiding congestion events that slow transmission. Testing showed transmission speed improvements of 400-1000% for some connections and up to 1400% for longer connections. While Extreme TCP can be applied as a software patch, its benefits are only seen on the device that has it installed, not requiring widespread adoption. It has the potential to significantly increase transmission speeds for most internet communications that use TCP.

Introduction to Tor
Tor is an anonymity network that allows users to browse the web anonymously. It works by routing traffic through a series of volunteer servers, or relays, that encrypt and then randomly route data in an attempt to make it untraceable. The Tor browser bundles this routing technology to allow users to access the open web as well as "hidden services" anonymously. While Tor provides anonymity, it has some weaknesses including potential traffic analysis of autonomous systems and exit node eavesdropping. The presentation provides an overview of how Tor works and relays, how to use Tor safely, and some common services found on Tor.

Onion protocol
Onion routing is a technique for anonymous communication over a computer network. In an onion network, messages are encapsulated in layers of encryption, analogous to layers of an onion. The encrypted data is transmitted through a series of network nodes called onion routers, each of which "peels" away a single layer, uncovering the data's next destination. When the final layer is decrypted, the message arrives at its destination. The sender remains anonymous because each intermediary knows only the location of the immediately preceding and following nodes.
Onion routing was developed in the mid-1990s at the U.S. Naval Research to protect U.S. intelligence communications online. It was further developed by the Defence Advanced Research Projects Agency (DARPA) and patented by the Navy in 1998. Onion Routing is implemented The Onion Routing project or TOR project.

The attacks tested were ping floods and Smurf attacks. Both servers were installed on the same Apple Mac Pro hardware platform to isolate the effects of the operating systems. The Windows Server was able to handle more legitimate HTTP connections than the Mac OS X Server under ping flood attacks, but crashed at a much lower bandwidth of Smurf attack traffic (150 Mbps) compared to the Mac OS X Server (500 Mbps). The study concludes that while Windows Server performed better against ping floods, its built-in protections were less effective against Smurf attacks

Proxy Servers
A proxy server acts as an intermediary between a client and the internet. It allows enterprises to ensure security, administrative control, and caching services. There are different types of proxy servers such as caching proxies, web proxies, content filtering proxies, and anonymizing proxies. Proxy servers can operate in either a transparent or opaque mode. They provide benefits like security, performance improvements through caching, and load balancing but also have disadvantages like creating single points of failure.
Proxy Servers
A proxy server acts as an intermediary between a client device and the internet. It allows clients on a local network indirect access to outside networks like the internet. There are different types of proxy servers that provide advantages like improved security and performance through caching but also have disadvantages like potential slower speeds. Popular proxy server software includes Microsoft ISA Server, Squid, and WinRoute, while common hardware proxies include Cisco PIX and Blue Coat.

The document discusses several methods for remote login and remote access to computers including telnet, remote shell, secure shell (SSH), remote administrator (Radmin), and WinSCP. Telnet, remote shell, and Radmin are not secure as they do not encrypt network traffic while SSH and WinSCP provide encryption and security. SSH is widely used on Linux and Unix systems to securely access shell accounts remotely over an insecure network like the internet. WinSCP is an open source SFTP and FTP client that uses SSH to securely transfer files between computers.
Remote Login- Noesis
The document discusses remote login and access to computers through various methods and software. It begins with an introduction and agenda covering remote login in Windows, Linux, and using pcAnywhere software. It then covers remote desktop protocol (RDP) used in Windows, virtual network computing (VNC) used across platforms, and how to use VNC on Linux via commands. Features, requirements, applications and security considerations are discussed for different remote login methods. Popular remote access software like pcAnywhere are also introduced along with screenshots and references.
Ssh And Rlogin
SSH (Secure Shell) is a secure login and file transfer protocol that encrypts all communications to provide strong authentication and secure login and file transfers over insecure networks. It closes security holes in other protocols like IP, routing, DNS spoofing and provides encrypted authentication and communications to securely redirect TCP/IP ports and allow remote access to systems like accessing a UNIX environment from Windows or working remotely on file storage. Other older protocols like RSH, Telnet and Rlogin are insecure in comparison.
Project Sparsh
Sankalp India Foundation has launched relief operation "Sparsh" to provide aid to people affected by floods in North Karnataka. They are collecting and distributing essential supplies like food, blankets, and household items to refugees housed in relief camps. Sankalp is coordinating with local groups and government to identify highest priority needs and distribute supplies effectively to those most in need. They are seeking donations from organizations and individuals to expand relief activities to additional affected areas in the coming days.
Remote Login
Remote login allows users to access and control a computer from any internet-connected device. It uses desktop sharing software that includes both a server program on the host computer and a client program. Common protocols used for remote login include Telnet, Rlogin, and Secure Shell (SSH). Popular remote login software options include UltraVNC, LogMeIn, UltraVNC SC, Crossloop, and PuTTY.
Http Proxy Server
This document discusses HTTP proxy servers. It defines a proxy server as a server that acts as an intermediary for requests from clients and acts as a client to the actual servers. An HTTP proxy server specifically handles HTTP requests. It can speed up browsing by caching frequently requested pages. It also anonymizes user requests and reduces load on the internet connection. The document then discusses the software Proxyfire as an example of a "distorting" HTTP proxy server and provides screenshots of its interface. It concludes by listing the hardware and software specifications of the system used.
Introduction To H1N1
The document discusses Swine Flu, its symptoms, spread, impact and status in India. It notes that while Swine Flu has spread globally and seriously impacted some countries, it is not the biggest health threat in India where other diseases like TB, Hepatitis and Malaria infect and kill many more people annually. The document advises basic precautions like hand washing and visiting a doctor for treatment. It emphasizes that most people recover from Swine Flu with basic medical care and there is no need to panic.
Anabhra Ratri Ki Anupama
