  • Announcing “BootAble” – GRC's New Boot-Testing Freeware
    Please see the BootAble page at GRC for the whole story.
  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

I came across a beta update for my router and it mentioned a hotfix for dnmasq related issues, so I did a quick Google and this turned up.


@Steve, could be a topic for the podcast.

This is a great test of your router vendor. This bug flies under the radar. Does your router vendor fix it? Do they say anything at all about it? My preferred router vendor (Peplink) was asked about it and found the vulnerable software in only one of their models and only in one specific use case. If you have a consumer router from Netgear, Linksys, Asus, TP-Link, D-Link, etc. try to see if they acknowledge this in any way.

I saw that update for my EdgeMax's. But I use BIND and so disabled DNS caching in my router. (I can't find (using a quick DDG search) whether BIND is susceptible to DNSpooq or not. Nor is there anything about pooq that I can find in the BIND 9.17.9 Release Notes.)

I also use BIND in my local network and I didn't realized that Edgerouter X is running another DNS service (dnsmasq) with it's own cache. Now I've disabled it. Thanks.
