Hi, I would like to make a request to members on getting tips on the following:
We would like to know how to make CLONING (the OS) from one Linux server to another server (without reinstallation). Can someone help us to achieve this?

But unfortunately, the link that BSNL gives works only with Internet Explorer. :-( But I think you can use Wireshark to analyze your network usage. Or else you can try creating a shell script. Be careful with torrents though! > gkrellm came handy to me for bandwidth usage.. thanks for your info.

(with perhaps the most comfortable performance zone for typical business app dev junkie) Preferably send the data our wire and measure the wirespeed and base your metrics on that. Including SAN if any. (storage Area _network_ right?) man start with some php-app end-to-end performance tuning. Whew!
