Hi,
Please suggest a best free software for simulating a linux web server and internal netwrok in a organization connected in LAN to test a web application for the organization. I would like to test everything in my laptop before getting to the location and setting up the routers, switches, web server etc.

Suggest me how to do it.

Thanks in advance

There's not much in one package like this. Really your best bet is use virtual box, create a web server mimicking their setup, or something similar. And access it from your laptop. Switches and routers are unlikely to affect the experience.

Thanks for your reply ryan461. Could you please elaborate the process? I can setup the virtual machine and install the linux os and deploy the web application in localhost. But after that how can I access it from the main Win 7 OS and how come this simulates the LAN scenario?
