Windows IP Commands – ipconfig-nslookup-ping-tracert-netstat etc

As Network Engineers we need to be versatile and troubleshooting-savvy in our work environment. In addition to having strong knowledge of networking protocols and commands on network devices (routers, switches, firewalls etc) we need also to have very good knowledge of IP and other networking related commands on end-point devices such as Windows computers, Linux […]

Network Failover Redundancy Scenario – Two sites with two ASA Firewalls

A few months ago I was involved in a project where we had to design a network redundancy scenario with two physically separate networks in two different buildings (the sites were a few kilometers away from each other). The main requirement was to provide Inbound Internet Access to two Server Pools (Linux Servers in High […]

GNS3 Graphical Network Simulator

GNS3 is a graphical network simulator that allows simulation of complex networks. To allow complete simulations, GNS3 is strongly linked with : * Dynamips, the core program that allows Cisco IOS emulation. * Dynagen, a text-based front-end for Dynamips. * Qemu, a generic and open source machine emulator and virtualizer. GNS3 is an excellent complementary […]
