The `whereami' package is a *great* way to achieve this sort of mobility. I have it configured to: * use the CRT or LCD based on monitor attachment * work out where I am via DHCP * auto-discover SOCKS servers on the network[1] * set mail to queue or deliver based on network connection * kick-start a couple of daemons when going from connected to roaming All of this can be done by writing some trivial shell scripts; whereami simply provides a framework for doing it. It's *really* easy to configure to do this stuff. There are a number of other packages that deal with the network discovery; whereami tries to address the issue of configuration as well. Other package, such as divine, are actually useful as *part* of the whereami system -- they can find what network you are on without needing a DHCP server running. Oh, and the last time I advertised his package here, the author asked if there were more features desired, which made me feel all loved and stuff. ;) Daniel Footnotes: [1] via hostname probe only, but you could extend this. :) -- The true way to overcome the evil of class distinctions is not to denounce them as revolutionists denounce them, but to ignore them as children ignore them. -- Charles Dickens

First thing I did and the one that I still do is write schemes for pcmcia that allow me to use the same kernel I am booting but with different labels in lilo.conf which will switch on different network settings. As an example, at work, I boot to a dhcp-managed network, so I have a theme called "work" in my /etc/pcmcia/network.opts file which has some network settings I need for there. Then I often take the same laptop home and use it wireless with a orinoco Gold card and a RG1000. I have a pcmcia theme and a label in my lilo.conf called "home" which allows me to boot a set of network settings for that environment. This has worked very well for me and you can setup your lilo.conf file to include label statements which will fire the corresponding section in /etc/pcmcia/network.opts for the settings you need. I also used this little program called netenv which you can apt-get which will allow a lot of flexibility with regard to network settings. I prefer the lilo.conf labels and the schemes in my /etc/pcmcia/network.opts file. BTW, I boot a debian unstable laptop which uses the 2.4.13 kernel for both settings with no problems.
