Telnet
Telnet is a network protocol used to provide bidirectional interactive text communication over a virtual terminal connection using TCP. It allows users to connect to remote hosts and access operating system command line interfaces. While once commonly used, telnet is now less favored for security reasons, replaced by more secure protocols like SSH for remote access. Most network equipment and operating systems still support a telnet service for remote configuration via telnet clients available on many platforms.
Team 5 presentation
Rlogin, Telnet, and SSH are remote access protocols. Rlogin and Telnet transmit information in plaintext, posing security risks, while SSH uses cryptography to secure connections. SSH was developed in 1995 as a more secure replacement for insecure remote shells like Rlogin and Telnet. SSH provides secure login, file transfer, and process execution between computers using encryption techniques like public-key authentication and symmetric encryption.
Network telnet ssh
This document compares the Telnet and SSH network protocols. It outlines that Telnet transmits data in plain text, was introduced in 1969, uses port 23, and has a light bandwidth. In contrast, SSH uses public key encryption for security, was introduced in 1995, uses port 22, and has a heavier bandwidth. It then provides step-by-step examples of connecting with Telnet and SSH.

Telnet & Secure Shell
Telnet is an early network protocol that allows text-based access to remote systems but lacks security features. It works at the application layer and provides bidirectional interactive text communication through a virtual terminal connection. SSH was developed as a secure replacement for Telnet, supporting encryption, authentication, and integrity to prevent eavesdropping and spoofing. It uses public/private key cryptography to securely transmit data and authenticate systems. While still used occasionally, SSH is now generally preferred over Telnet for remote access due to its enhanced security.
Telnet & SSH
Telnet is a protocol that allows administrators to remotely access and manage devices, but it transmits usernames and passwords in clear text, posing a security risk. SSH is a more secure replacement for Telnet, as it encrypts all transmitted data using public key cryptography. Both protocols require a client and server, with Telnet using port 23 and SSH typically using port 22.
Report on telnet
Telnet is a network protocol used to provide bidirectional interactive text communication over TCP. It allows connecting a client (with display and keyboard) to a remote command line interface. Telnet uses ASCII encoding and negotiates options to support advanced functions. While it provided remote access historically, security issues have led to decreased use for that purpose in favor of SSH.

The known unknowns of SS7 and beyond
The talk was given at Troopers 2016.
(https://www.troopers.de/events/troopers16/654_the_known_unknowns_of_ss7_and_beyond/)
Abstract:
2014 turned out to be "the year of SS7 vulnerabilities" as the Telco researchers showcased several successful attacks using the Signaling System No 7 (SS7) interconnection network such as subscriber profile modification, eavesdropping, tracking of users, SMS spoofing and call/SMS redirect. These attacks are serious because SS7 and its IP version SIGTRAN, despite its age, remains a key signaling protocol in the mobile networks and will still long be required for interoperability and background compatibility in international roaming. Understandably, telecommunications industry is taking countermeasures against the vulnerabilities that were exposed through the aforementioned attacks.
Are all risks now mitigated?
Definitely not!
Complexity of network layers and diversity of underlying protocols in SS7 makes it more difficult to find all loopholes in the systems. There exist a lot of 'known functionalities' which are indeed the 'unknown vulnerabilities'. In this talk, we first begin with one of such vulnerabilities in detail, where we discuss how to exploit the relationship between IMEI and IMSI to unblock stolen mobile devices. Here, we also discuss about the existing attacks on modification of subscriber profile using SS7 to recap about the contents of subscriber profile. Secondly, we will outline extending the previously known SS7 based attacks to Diameter/LTE. Furthermore, we will also present with an intuitive attack vector to emphasize the fact that the telecommunication systems are being misused for surveillance.
Internet ports abduilla
This document lists various internet ports and provides a brief 1-2 sentence description of the service or protocol associated with each port number. Some of the ports covered include port 23 for Telnet, port 25 for SMTP email, port 53 for DNS, port 80 for HTTP, and port 443 for HTTPS. The document provides a high-level overview of many common internet ports and their associated network protocols and services in a concise format.

This document summarizes a paper on packet filtering as a basic network security tool. It defines packet filtering as controlling network access by analyzing packets and allowing or blocking them based on header information like source/destination addresses and ports. It then discusses how packet filters work by examining these header fields, provides an example Linux configuration, and outlines some limitations like inability to inspect payloads or track connection state. It concludes by describing common applications of packet filtering like ingress/egress rules to block spoofed addresses and unoffered services.
Vulnerability analysis of OpenFlow control channel
The document summarizes research on vulnerabilities in the OpenFlow control channel and potential attacks. It describes conducting a man-in-the-middle attack on an OpenFlow network by sniffing OpenFlow traffic, sending a TCP reset to hijack the control session, and spoofing the controller. It also evaluates the OpenFlow specification making TLS optional and proposes using TLS and padding messages to prevent sequence number prediction attacks. The document analyzes several OpenFlow controllers and their TLS support and concludes more needs to be done to securely adopt SDN technologies.
Ip sec
IPsec is a standardized framework that provides security (encryption, authentication, integrity) for IP communications. It has two modes - Transport mode which encrypts only the payload, and Tunnel mode which encrypts both the header and payload. IPsec uses protocols like AH (Authentication Header) which provides authentication and integrity, and ESP (Encapsulating Security Payload) which provides confidentiality, authentication, and integrity. IPsec implementations can be in end hosts or routers depending on network requirements.
Road
The document summarizes a dangerous drive along the Stremnaya Road in Bolivia, nicknamed "the road of death" due to its perilous conditions. The driver encounters hairpin turns, passing other vehicles going over 80 mph, and nearly colliding with oncoming traffic around blind corners. By the end of the harrowing ride, the driver asks if the person will ever complain about traffic on safer highways again.

Telnet
Telnet is a network protocol used to provide bidirectional interactive text communication over a virtual terminal connection using TCP. It allows users to connect to remote hosts and access operating system command line interfaces. While once commonly used, telnet is now less favored for security reasons, replaced by more secure protocols like SSH for remote access. Most network equipment and operating systems still support a telnet service for remote configuration via telnet clients available on many platforms.
presentationweek11
Telnet is a network protocol used to establish interactive text-based communication sessions over TCP/IP networks, allowing users to log into remote systems. While it was one of the first internet standards developed in 1969, telnet's security is poor as usernames and passwords are sent in plain text, so its use is now discouraged in favor of more secure protocols like SSH.
Application layer and protocols of application layer
The document summarizes several key application layer protocols: Telnet allows remote access to servers by emulating a terminal. FTP is used to transfer files between machines. TFTP is a simplified version of FTP with no security. NFS enables accessing files over a network like local storage. SMTP is the standard for email services. LPD/LPR is for remote printing. X Window provides GUI functionality over networks. SNMP allows monitoring of network devices. DNS translates human-readable names to IP addresses. DHCP automatically assigns IP addresses to devices on a network.

Telnet is a terminal emulation program that allows users to connect their PC to a server on a TCP/IP network like the Internet. This enables users to enter commands on the server as if they were directly accessing the server's console. NVT refers to a virtual terminal with keyboard and printer capabilities defined in RFC854. IP addresses distinguish between the network and host portions of an address using a subnet mask. Routers relay data between networks by analyzing network and transport layer protocols to determine the best path for data transfer.
Week11 F
Telnet is a network protocol that allows users to access remote hosts and run commands. It works by negotiating terminal emulation between the client and server so that keyboard inputs and screen outputs function properly. When a user enters a command via their local terminal, the data is sent to the remote Telnet host which processes it and returns the results, though there may be delays during this process as data travels over the Internet.
TCP_IP.pptx
TCP / IP protocol.
Welcome to our comprehensive PowerPoint presentation on the fundamental concepts of TCP/IP (Transmission Control Protocol/Internet Protocol). This presentation is designed to provide a clear and insightful overview of the TCP/IP model, a cornerstone of modern networking.
Deeps
TCP/IP is a core internet protocol that provides reliable data transmission. TCP ensures reliable and ordered delivery of data between applications on different computers. It detects lost packets and requests retransmission. IP delivers packets based on their addresses from source to destination. FTP is used to transfer and manage files over TCP/IP networks between client and server applications using separate control and data connections on port 21. SMTP is the standard for email transmission over IP networks in a text-based format. Common network utilities include FTP, TFTP, Telnet, Ping, Traceroute, Ipconfig and Nslookup for connectivity and diagnostics.
"Internet Protocol Suite" prepared by Szymon M. from Poland
The document summarizes the Internet Protocol Suite (TCP/IP), which is the set of communication protocols used for the Internet and similar networks. It consists of four layers - link, internet, transport, and application layers. Some important protocols included in each layer are IP, TCP, UDP, and higher-level protocols like HTTP, FTP, and SMTP. The TCP/IP model uses encapsulation, adding headers at each layer to abstract the protocols and allow communication across networks.
Network protocals.pptx
TCP/IP allows computers to communicate over the Internet by compiling and sending packets of data to the correct location. DHCP automates the configuration of devices on IP networks, allowing them to access services like DNS and use communication protocols based on UDP or TCP. Ethernet is the most widely used method for connecting computers in a local area network since the 1990s, allowing multiple devices to send data at any time. HTTP transmits hypermedia documents like HTML between web browsers and servers but can also be used for other purposes, while FTP transfers computer files between clients and servers using separate control and data connections.
Ch4 Protocols.pptx
Protocols define the rules and format for how computers exchange information over a network. The key features of protocols include syntax, semantics, and timing. There are two main protocol models - the TCP/IP model and OSI reference model. TCP/IP is comprised of four layers including network access, internet, host-to-host transport, and application layers. The OSI model has seven layers and provides a framework for developing networking standards. Common protocols like TCP, IP, UDP, HTTP, FTP and SMTP control how different aspects of networking like file transfers, email, and web browsing function.
Ip
The document discusses several internet protocols including the Internet Protocol (IP) which defines how data is sent between computers, Ethernet which describes how networked devices can format and transmit data on the same network, and Transmission Control Protocol (TCP) which establishes and maintains network conversations for exchanging data between application programs. It also summarizes the Domain Name System (DNS) which maps domain names to IP addresses, User Datagram Protocol (UDP) which is used to establish low latency connections, File Transfer Protocol (FTP) for transferring files between client and server, and Dynamic Host Configuration Protocol (DHCP) which automatically provides hosts with IP addresses and configuration information.
Routed Protocol
A Routed Protocol is used to deliver application traffic. It provides appropriate addressing information in
its Internet Layer (Network Layer) addressing to allow a packet to be forwarded from one network to
another. Routed Protocols are nothing more than data being transported across the networks.
History of tcp
The document provides a history of the development of TCP/IP from its origins in research conducted by DARPA in the late 1960s through key milestones and protocols introduced through the 1990s. It discusses how TCP/IP became the standard protocol suite for the Internet and how its evolution is overseen by organizations like the IETF and RFC standards process. Key terms related to TCP/IP networking components like nodes, routers, hosts, interfaces and subnets are also defined.
Ch4 Protocols.pptx
The document summarizes several key networking protocols. It begins with an overview of protocols in general and the two main protocol models: TCP/IP and OSI. It then describes some of the most widely used protocols for various functions: SNMP for network management, HTTP and HTTPS for web communication, DNS for domain name resolution, DHCP for dynamic IP address assignment, SMTP for email transmission, FTP for file transfer, TCP and UDP for transport layer functions, IP for network layer packet delivery, and ICMP for reporting network errors. The document provides details on the purpose and basic operation of each protocol.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
