GNS3 Alternatives

Virtual PC Simulator is an open-source software running on Linux and Windows, where only limited network commands can be used. It is an ideal tool to use in simulated networks such as GNS3 as it has developed from a simple to a robust testing ACLs tool. Because of the detailed output of ping replies and commands such as to see packet dumps, etc., made it a toolkit for the networking engineers.

Virtual PC Simulator simulates up to 9 PCs, and it is more useful than traditional PCs because it can send and receive UDP and TCP pings. From the virtual PCs, you can ping or trace out the other routers or hosts when you learn the Cisco routers in the Dynamips. It can substitute the routers or VMware boxes used as PCs in the Dynamips network.

When it starts, it attends the ports from 2000 to 2008 and delays the dynamips to connect and sends the packets to the ports from 3000 to 3008, which would be accompanied by the dynamips.

The external interface allows passing the prompt network data to another tool such as SUMO and MATLAB etc. The software can run its computer engine and sends back information to NetSim, which utilizes this output to transport its network simulation routines.

Dynamips is a computer program that is written in C language to emulate Cisco routers. It allows users to be familiar with Cisco devices, test, and experiment features of Cisco IOS and to check rapidly the configurations deployed on real routers.

To compile Dynamips, you need a working GCC or Clang compiler and CMake build system. You can accumulate two different varieties of Dynamips with this code, and to set the flags, you have to edit the Makefile.

There are two flags that are called stable or unstable. You should prefer the use of a stable flag, although it contains the same code as unstable. But it minuses some mips64 bit optimization and the code that seems to activate instability on several platforms.

The unstable code contains most of the development code and is suitable, especially for 64 bit Mac. It is unstable on other platforms. You can consult your distribution package list to find the similar packages available for most distributions.

Live Raizo is open-source software and a live distribution based on a virtual Linux machine called Debian that comprises various network tools and services. It also includes tools to interrelate with real devices such as Wireshark and minicom, as well as SSH, HTTP, and TFTP servers.

Its core features allow you to build a complex virtual network with drag and drop options. You can link with hubs or switches and utilize server or router as a client because you have simulated machines based upon Debian. You can introduce your OS if it is compatible with Linux, Microsoft, and ASA Firewall. You can connect your simulated network with the physical system using drag and drop options.

Many network tools are already available on Debian VMS, and it allows you to install tools you need like Linux / Debian, etc. You can also modify LiveRaizo with remote scripts that emerged on a server. A minimal window manager increases the memory of the CPU for the virtualization.
