Network Notepad 6.0.21 Free Edition – Cisco Packet Tracer Alternative

Cisco Packet is one of the most popular applications that you can use to draw and simulate networks. Packet Tracer allows you to design complex and large networks, which you often can't do with physical hardware due to cost. With such capable capabilities, of course,  you need a computer device and the appropriate skills to be able to use all the features of Packet Tracer. You can download Packet Tracer here. Network Notepad is a freeware application for creating interactive network diagrams.  With this app, you can quickly draw a network topology. If you only need to draw diagrams or network topology, Network Notepad is the right choice. Network Notepad has a fairly complete object library that allows you to draw all the common objects in the network. In addition, this application also has a small size, so you can run it on a computer with low specifications.

How to Install Nmap with GUI in Windows 11

How to Install Nmap with GUI in Windows 11

Nmap is becoming one of the most popular tools for scanning and mapping networks and for finding weak spots. Nmap (Network Mapper) is a free software for security auditing and network scanning. Many systems and network administrators use it for activities such as network inventory, service update schedule management, and monitoring host or service uptime. Nmap uses new techniques to detect active hosts on the network, available services (application name and version), operating systems, packet filters/firewalls, and hundreds of other characteristics. The app is designed to quickly scan large networks, but it also works well against a single host. Main feature Flexible: Supports hundreds of complex approaches to mapping a network full of IP filters, firewalls, routers, and other bottlenecks. Many port scanning techniques (both TCP and UDP), OS detection, version detection, ping sweep, and other features are included. Please see the documentation page.Powerful: Nmap scans large...

Windows Server Core 2019 – Step-by-Step Installation and Configuration

Windows Server Core 2019 – Step-by-Step Installation and Configuration

Windows Server Core is a minimalist version of Microsoft Windows Server. The major difference between Server Core with other versions is the absence of a desktop display and all configuration and maintenance are carried out using a command-line interface. Server Core has been introduced since the 2008 generation of Windows Server. The Server to function properly does not need a graphical user interface (GUI). The GUI of the server only serves for ease in performing configuration and maintenance. Without a GUI, Windows Server Core has the advantage of using resources such as disks and smaller memory, so that these resources can be maximized for services. And in terms of security, Server Core is much safer from surface attacks against the operating system. Installing Windows Server Core In this tutorial, Bardimin uses Windows Server 2019 as an example. For the installation of other versions, it is almost the same. You just have to adjust.

LOW Orbit Ion Cannon (LOIC) – DDoS Tools – Network Stress Testing

LOW Orbit Ion Cannon (LOIC) – DDoS Tools – Network Stress Testing

Low Orbit Ion Cannon (LOIC) is an open-source network stress and denial of service testing application written in C#. LOIC was originally developed by Praetox Technologies, but was later released into the public domain and is currently available on several open-source platforms. LOIC performs DoS attacks (or, when used by many individuals, DDoS attacks) on target sites by flooding servers with TCP, UDP, or HTTP packets with the aim of interfering with specific host services. Although downloading and using LOIC on a private server as a means of stress testing is legal, at least in the United States, using a program to carry out DDoS attacks on others can be considered a crime under the Computer Fraud and Abuse Act of 1986.  LOIC Features SecurityStress Testing Disclaimer: Use it at your own risk.

GNS3 Version 2.2.33.1 – Network Software Emulator

GNS3 Version 2.2.33.1 – Network Software Emulator

GNS3 is widely used to simulate, configure, test, and troubleshoot real and virtual networks. GNS3 allows you to manage topologies of any size, from those with multiple devices hosted on your laptop to those with multiple devices spread across multiple servers or even hosted in the cloud. GNS3, which at first could only emulate Cisco hardware using a program called Dynamips, has developed and can emulate various network hardware, including virtual switches from Cisco, ASA from Cisco, Brocade vRouters, Cumulus Linux switches, Docker instances, HPE VSR, various Linux appliances, and more. GNS3 supports not only Cisco hardware. However, GNS3 now supports a variety of additional open source and commercial suppliers. Networking technologies with SDN, NFV, Linux, and Docker allow you to test interoperability among different manufacturers and even try out unusual settings. Advantages of Using GNS3 Free softwareOpen Source softwareNo monthly or annual license feesThere is no limit to the...

Angry IP Scanner–The best and fastest network scanner

Angry IP Scanner–The best and fastest network scanner

Angry IP Scanner is an open-source and cross-platform network scanner designed to be fast and easy to use. This scanner can scan IP addresses and ports and has many other features. The application is also widely used by network administrators and practitioners around the world, including large and small companies, banks, and government agencies. Angry IP Scanner uses several methods to detect hosts that are still alive (ping). Hosts that do not respond to ping are considered dead and not scanned further. This behavior can be changed in the Scanning tab of the Preferences dialog. You can also select the ping method from the same menu. By performing a reverse lookup, Angry IP Scanners displays the host-name returned by your DNS server (name). The server is assigned an IP address and, if known, returns the host-name. If a computer knows its name, it does not mean that it has given it to a network DNS server. The familiar host name (local name) and the name known by the DNS server...

Router Default Passwords – Application to get router IP and Password

Router Default Passwords – Application to get router IP and Password

Router Default Passwords is a portable application that can find the default gateway address and also the default user and password of the router device. A router is a device that connects two or more networks or subnets and manages traffic between networks by forwarding data packets to the destination IP address and allowing multiple devices to use the same Internet connection. You may need to know the IP address of the default gateway if there is a network problem or if you need to change your router. The IP address of the computer's default gateway can be accessed through the Command Prompt with the ipconfig command, as well as through the Control Panel. The netstat and ip route commands are used on macOS and Linux to find the default gateway address. To access the admin dashboard of a router, you need to know the gateway address of the network you are using. Features of Default Passwords Router Able to find the default IP address of the network gateway.It has a default database...
