I think I need it. I’m too often walk between different networks with my laptop. Every time I need to change proxy settings in all my browsers and all web apps (Miranda etc) that works through HTTP/HTTPS proxy server. This is not only proxy address and port — some of them requires authorization.

So, it would be good to found small non-caching, non-doing-anything-at-all proxy server running on my laptop, that could do only one thing: switch between different presets.

Started googling, I found tip how to switch proxy and other settings by command-line tool netsh (post from 4:25 10 May 2004).

Windows already has the ability to store and retreive network configs!

to save the configs: netsh -c interface dump > configfile1

reconfigure to e.g. home use, then do netsh -c interface dump > configfile2

to load the configs again, do netsh -f configfile1

and you’re done. To make it easier to switch, create shortcuts to the netsh tool with the params to the config files.

It is not what I need, but maybe will be of use in some another situation..

(…) A weird imagination is most useful to gain full advantage of all the features. (…)

This is from man screen.

Ethernet card in my (not-very-new) laptop is on sis900 chip. By default it has Mac address 00:00:00:00:00:00. Just imagine two such cards in one network segment… And I need to put something sensible in DHCP server config file.

In Windows this is not a problem, just specify MAC address for card in “Device Manager”.

But I have Debian as second OS on my notebook. The solution was not complex at all, but takes some time to found it, so I publish it here.
