Hey John, It's tough to go by me as I have not attended in too long a while. I can say for me personally May 8th is booked. The 15th looks ok.

Re: If you use putty or puttygen, update to the latest version..

by Tim Keller

Keith: Putty is an SSH client for windows. On a very cool side note, my co-worker Nick Howgrave-Graham, who a couple years ago came and gave a talk about encryption and math and public private key stuff. The researchers who found this flaw cited his work.. Quote from the PDF: Many works in the literature have exploited side-channel information about (EC)DSA nonces by solving the Hidden Number Problem (HNP), e.g. [65, 19, 55, 12, 70, 75, 71, 63, 80, 46], since the seminal works of Bleichenbacher [18] and Howgrave-Graham and Smart [45]. Nick is a brilliant guy and it's cool that his work is still being used to find flaws. Tim.

Re: Great meeting last night! --- Sorry I couldn't stay

by Jon "maddog" Hall

Keith, >Does jitsi create rooms upon demand from anyone? Jitsi has two main methods of operation that I know of: o create an "on demand" room by generating a unique string that you can pass to the other people and everyone joins via that string o create a "moderated" room which has two URLs generated, one for the "users" and one for the "moderator". You get this type of room by clicking on "book a meeting URL" right under the normal window that says "start meeting" at the top of the Jitsi Meet page. With regards to the sound, I have a Thinkpad X1 and when I use the 3.5mm audio jack on the side I have not been able to get the microphone to work properly, so I use a USB sound card or USB headphones to hear and speak. This requires me to configure the sound options on the system. You can also select which speakers and microphones you want to use in the Jitsi application itself right before you "join the meeting". Just click on "settings". You may have to dicker with the volume a bit in your system settings. On the other hand my X1 now uses solid state storage and has a very soft fan (if it turns on at all) so sometimes I do not use any microphone or speakers other than those with the laptop. md On Fri, Apr 12, 2024 at 12:33 PM Keith Wright via WLUG <wlug(a)lists.wlug.org> wrote: > Kevin Stratton via WLUG <wlug(a)lists.wlug.org> writes: > > > I was able to connect using https://jitsi.uvhash.org/WlugMA%20uvhash.org, > but > > I was the only person (as a moderator) in the lobby at 7:20.

I've mostly seen putty used by Windows users, and Linux users that recently moved from Windows. If you were using it, you would know. You should be good.

I had never heard of Putty, but this sounded dire. There are many things that I never heard of that are installed by my Linux distribution (Debian) and are essential for it's operation. Do I have putty keys lying around? I Google search reveals that this question has been asked by many other people and answered by many more people who have no idea what they are talking about.

Putty just announced that versions earlier than 0.80 were generating ecdsa-sha2-nistp521 that were flawed.. If you have any of these keys lying around, destroy them and regenerate keys. Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
