DSL and Puppylinux seem to be very good. Nothing like setting up Ubuntu as it is a full blown linux. Pendrive linux seems to have started from Mandriva and unlike Mandriva Linux, i think this is also Free. > Also, lemme know if there is a USB stick > based linux flavour that would support virus > scanners ? > > No clear info from internet so far. > A) Ubuntu based USB has Synaptic Packet Manager system that could be used to install, remove, configure, or upgrade software packages, browse, sort and search the list of available software packages, manage repositories, or upgrade the whole system. https://help.ubuntu.com/community/SynapticHowto I think, this can be used to get the virus scanner onto the USB stick once the Ubuntu is up from the USB stick. Need to check. But, No clear method is available on the method of addition of new software. Any ideas ? B) In Puppy linux, i found specific statements that convey that one can use antivirus that is built-in or can be installed in Puppy. http://puppylinux.org/main/index.php?file=Overview%20and%20Getting%20Started.htm But, did not get a clear link on the method of addition of new application to it. Any ideas ? C) Pendrivelinux also seems to be full blown linux, and the virus scanner can be installed just as this application is installed in the below link - http://ubuntuforums.org/showthread.php?p=8465858 Lemme know if this Pendrivelinux method fine as conveyed in above link ? > > As I gather, the cost is not too high, but > > alternatively, you can do it yourself using a freely downloadable > > distribution and a USB memory stick you already own.

You are not going to find one, since USB sticks cost money. Most distributions do however have the necessary tools for creating a USB-stick-based GNU/Linux distribution, and some may even have preconfigured and automated utilities to do such a thing for you. > Also, lemme know if there is a USB stick > based linux flavour that would support virus > scanners ? Google is your friend. > No clear info from internet so far.

The 2.6 kernel doesn't even fit on a floppy anymore, so you'd be stuck with an old kernel, which may not support all of your hardware. For instance, I don't even know whether 2.4 supports SATA hard disks. > I know of MiniRTL(based on busybox) that did > not have dependency on HDD except for the RAM > (Even the RAM requirement is very minimal). > Other than that, there are other flavours like > 'Tomsrtbt', Asmutils based 'a-Linux' and various > other Busybox based flavours. But,they are all > Floppy based. If they are floppy-based, then they will certainly not hold any decent antivirus software, given the size of such software suits. > But, floppy drive is not available in that machine :-( Then why even consider it? ;-) > Does tomsrtbt support USB stick based boot up ? That is not what it was designed for, but in theory, you should be able to make a bootable USB stick with the contents of that CD, yes. On the other hand, you'd be far better off with a more complete distribution, e.g. Knoppix. > I may check with the tomsrtbt user list regd this. > Incase you have any information w.r.t tomsrtbt > you can lemme know. I can't really help you with that. I've only used it once or twice, in order to detect hardware errors on one of my machines. > Another query that pops in my mind is > that these minimal versions/flavours of linux > might not have lot of features.

Yes, that is what I wrote higher up already. You'd be far better off with a "real" distro. There are several live-CD based distros, and other distros allow you to make a live-CD with a few simple mouseclicks, or a bootable USB stick. Look here and see whether you can find something to your liking: http://www.distrowatch.com > Incase these minimal versions are not suitable > for existing along with virus scanning utility in > the USB stick, do lemme know. They will probably not have such scanners "on board", so you'd have to add them yourself. The simpler the base you start from, the more work you'll have at producing a bootable USB stick with a working distro *and* a virus scanner. > PS - Have looped in comp.os.linux.embedded > to get their thoughts also as it is going towards > that direction also interms of footprints,utilities > in FD based linux, USB stick based linux , > Tiny linux flavours having support for virus scanner > etc. USB sticks and floppy disks are not "embedded Linux". Embedded (GNU/)Linux is what you find in routers, cellphones and satnav systems, i.e. the "system on a chip" approach. Such systems usually don't come with antivirus software, and most of the time those devices are configured to not work as if they are complete UNIX systems. For instance, a Linksys WRT router has a Linux-based system in firmware, but other than approaching it via a webbrowser to make a few changes to the settings, you can't do much with it, since the device was never designed for any other purposes than being a router. Alternative firmware downloads do exist, but they really *are* alternative, i.e. you'd have to install it yourself. And for your intended purposes, the issue is moot. -- *Aragorn* (registered GNU/Linux user #223157)

This is interesting. I searched for setting up ubuntu in USB stick and the below link - http://www.pendrivelinux.com/usb-x-ubuntu-610/ Another link that claims the installation of ubuntu in USB stick from Live CD is below - http://www.techbuzz.in/installation-of-ubuntu-in-a-usbflash-drive-from-the-live-cd.php Does clamav come by default after following the procedures mentioned in the below link ? http://www.pendrivelinux.com/usb-x-ubuntu-610/ Or, should we need to add clamav by setting up the network/internet once the ubuntu is up from the USB stick ?
