    I may be heading down to Biloxi Mississippi in the next few weeks to help coordinate the computers in a relief office and offer my repair/recovery skills. One of my most important tools down there will be LiveCD/USBs of Slax, Ubuntu, etc. It will allow for some recovery but mostly establishing a quick network with free software in the wake of many computers being damaged/destroyed by flood.

      The wiki articles on how to do this with Gentoo haven't been updated in well over a year. A large amount of the information is no longer valid. I actively work on development of a Forensic and Network Analysis Live CD based off of Gentoo. For the best advise on how to really get going with this, look into Catalyst and make sure you emerge it with the documentation. It will walk you through the basics. If anyone wants a link to my development page drop me an e-mail and I'll be happy to point the way. I'd simply post it but I doubt the server would take the beating very well.

    If nothing else, I've got a recent (if not latest) version of Knoppix and the latest Ubuntu LiveCD, which pretty much covers most of my needs in a disaster...whether it's an actual need for a bootable machine for internet access and word processing...or actually getting information out of a HDD when the underlying OS got borked one way or another.

    The article goes on to feature the other quickfix distros including DamnSmallLinux and the LTSP to get a bunch of networked PCs up and running quickly.

    In a disaster, I must say that content filtering (and possibly time management) aren't my priorities but I guess to keep some sense and order on things, they're needed. However, something to boot with, something to get networking with, something to type something with, and something to save information to would make up my computing needs when some disaster hits.
    • However, something to boot with, something to get networking with, something to type something with, and something to save information to would make up my computing needs when some disaster hits.

      I'm thinking network and printer drivers are going to be the gotchas here. And maybe video drivers, although it's been a while since I haven't been able to get at least a 640x480 KNOPPIX X.

      Actually this highlights the need for open hardware standards.
      • >>I'm thinking network and printer drivers are going to be the gotchas

        Pretty small gotchas these days. You'd be suprised how much thin client hardware is autodected under LTSP. It has come a very long way.

        • Come to think of it, my scope of late is farily narrow...mostly KNOPPIX 3.7 (yeah, need to update) on work PCs not recognizing the Broadcom Xtreme gigabit adapter.

          On the other hand, part of my poorly-made point is that new hardware keeps coming out and needing new drivers, so a disaster LiveCD is going to have to keep being updated to avoid going stale. Usually you want your disaster stuff to be unperishable.

    It's really important in environments like that to have a web server system, so you'd want Apache or THTTPD or some alternative, and you need SAMBA because somebody's going to have a Windows box you need to talk to. And obviously you're going to want some wireless tools to help you build wireless networks - at least Netstumbler.

    A USB memory stick is really useful if you want to make servers run on unknown-condition hardware, and a USB hard drive can give you more space and power if you want to haul that around. Somebody else mentioned having various USB tools so you can download from digital cameras and other random devices.

    If you've got a mapping program that you can fit onto your CDs, that can be really helpful also, in case people don't have the bandwidth to get to Google/Yahoo/Mapquest. I don't know of any that run on Linux (I've got some old ones that run on Windows, and on Linux machines I just use Google), but I assume there are some out there that can read Tiger data.

    This is a great example of the failure of single source solutions, specifically FEMA's IE6 only site. Sure it is easy to maintain a single source solution and it can help to keep costs down. Unfortunately, in this case it failed to be open enough to provide help to the people it was designed to help nor did it support the people it was created to support. In a disaster you will be lucky to get anything in the way of hardware, software and support, so the environment to support the disaster teams needs to be very very forgiving. Too bad it wasn't.

    During Hurricane Katrina, the Internet proved its value during disasters and disaster recovery. It was available when the TV and radio stations were flooded out or blacked out.

    During the initial recovery, instead of having to fill out reams of paper, people were able to electonically submit their information over the Internet.

    Instead of overloading the Post Office with "Where are you?" notes and "Here I am!" responses, people were able to use the Internet to send E-mail.

    Face it, people - the Internet did what it was supposed to do: stay connected even during emergencies. We've gotten used to it, our non-immediate disaster relief efforts now expects Internet access, and we made use of it when the usual media failed.

    So, posters who ask, "Well, what do they need Internet access for at a shelter?" - I offer my answer.

They kept the network running continuously and without incident for around two full days.

      • Yes, you're right.

        Amateur Radio regularly schedules "Field Days", where a simulated emergency is posited, and people have 24 hours to make as many radio contacts as they can. IIRC, their score is also affected by the conditions under which they operate... contestants using 110-volt wall current have to make more contacts to score as high as those using gasoline-powered generators.

    Once victims were in places like shelters with power they would need access to various agencies' forms. The would also be able to do some emails or post to victims forums.

    Old PCs donated to shelters would be handy as well. Heck, make sure the system boots with the live "disaster" disc or usb thing

    I've been working with my local Red Cross (in Canada) to create just such a disk. We tentatively named it "RedCrossix" and it is based on Knoppix 3.6.

    There were a couple of key goals when we created it:
        -Needs to be able to boot from CD OR install to HD.
        -Must be secure (unable to read/write hard disk) of borrowed PC, unless you do install.
        -Very simplified desktop and menu structure in KDE. Web Browser / Email / Word processor / Games.
        -Needs to auto-detect hardware (thanks Knoppix team for this..)
        -Customization (red-cross wallpaper, splash screens, etc).

    It's actually pretty simple to take Knoppix and do this. If anyone's interested, reply and I'll post my notes later tonght when I get home (after 11pm MST - North American Time).

    At our local shelter, the Cajundome, the IE6 FEMA problem was major too. Although intially some machines were loaded with a Linux distro (I don't know which), this issue prevented them from being used. Fortunately, some guy walked in and offered a bunch of Win2k machines, that we could get IE 6 to run on. Once we had them up and running though, the FEMA site tanked.

    In the discussion section, some people have argued that net connectivity is less important than food and shelter. This is true. However, the web site was the only way for most people to get registered with FEMA. As this is one of the most important tasks, once basic needs are met, network connections should not be under estimated. A good word should also be given to Yahoo, for providing free e-mail accounts. Last time I used this system (ages ago), they required a referring e-mail address. They no longer require this. This was crucial, as FEMA require an e-mail address to complete the registration process. That being said, it is a shame that FEMA (known in these parts as 'The Finally, Eventually Made-it Agency) has otherwise been so damn useless.

    There was another lab where people could have more general net access. There many people seemed to find a huge sense of relief in being able to see their houses on google, even when the houses were under water. One older man I helped was totally blown away at the idea of seeing the Ninth ward of N.O from space. He wept when he saw that his house still had a roof, and then started making jokes about how the fishing would be good from his porch! For a person who has lost everything, anything that can bring a bit of joy is very valuable indeed.

    Another point needs to be raised in the context of this liveCD discussion. This is the fact that on many older machines (I know this, as I have alot of practice with these), the CD drive is one of the first things to fry. This is a problem.

    One final point, in the article, there is a discussion of the role of M$ in the disaster relief in this State. The current 'official' State operating system is Win2k. So, they will have been especially motivated to assist a good customer. However, from time to time we hear rumours that the State is going to make M$ software mandatory (I work for a State of Louisiana institution). Fortunately, this hasn't happened yet.

    Just my 2 cents.

    • Up until the early '70s, we had Civil Defense, run locally by volunteers who knew the area. Then, that was dismantled and replaced by FEMA; a centralized bureauocracy headquarted in DC and therefore unable to have any local knowledge. Of course it's slow to respond, and believes in "one size fits all" solutions like forcing people to register on-line with one and only one browser. Thank you, Jimmy Carter for foisting this on us.
  • A few posts here seem to miss the importance of internet access in disaster recovery. The only way we could apply for FEMA aid was through the website(which crashed every other time we logged on). The phone lines(which mostly never went down) were clogged for weeks and probably still are.

    Getting in touch with friends and family, receiving information on the extent of the disaster and applying for aid make access essential.

    The Red Cross IT folks are really, really picky about what is used on their networks and what is used in their name. The Red Cross has a procedure in place to bring internet connectivity to a shelter, HQ or service center and it doesn't include linux. I spent three weeks as a "RTT" member in the Gulf Coast, they use Windows for everything and either bring in a T1 or use in-house VSAT equipment (either an ECRV or a fly-away kit) for network connectivity.

    While FEMA website access works great, the ARC proxy server blocks out all webmail access. Nothing like thousands of volunteers and clients being unable to ping family about how they're doing.

    And an off-topic note - the ARC is doing some amazing innovation in the field of emergency IT.
