Re: Zeek - from yesterday's meeting

From time to time I used a USB Ethernet port: https://www.bestbuy.com/site/shop/usb-to-ethernet-adapter Generally they are about 25 USD. You might be able to find them on Ebay or other places for less than that. You might as well get a USB 3.0, since it will work with USB 2.0 ports, but USB 2.0 will not support 1 Gbit/second, whereas USB 3.0 will. On the other hand if the networking flow is not 1 Gbit/second then USB 2.0 might work fine. I have found the Linux support for these generic USB Ethernet devices to be generally good. md On Fri, Apr 9, 2021 at 5:09 PM John Stoffel via WLUG <wlug(a)lists.wlug.org> wrote: > > Guys, > I'm looking into Zeek and unfortunately I don't have a second ethernet > port on my main system, so it's not clear how I'd run a span port off > my main switch to grab traffic. > > What hardware do people recommend for a zeek data collection node?

Zeek - from yesterday's meeting

by John Stoffel

Guys, I'm looking into Zeek and unfortunately I don't have a second ethernet port on my main system, so it's not clear how I'd run a span port off my main switch to grab traffic. What hardware do people recommend for a zeek data collection node? I guess I could spin up my old WRAP board (http://www.pcengines.ch) which I used as my main router for years before I replaced it recently. But it's not super fast. It's got three 1gb ports, and 4gb of RAM with a 1Ghz single core AMD CPU. So it might do the job, esp since I can install Debian Buster on there without too much trouble. Sweet! John

Reminder! We've got a meeting this Thursday (April 8th, 2021!)

by Tim Keller

Hey Everybody, This is a reminder that we have a meeting on April 8th, 2021. Same bat time, same bat channel Date: April 8th, 2021 7pm: Jitsi @ https://meet.jit.si/WlugMA Topic: As of yet, there's no topic for the meeting, however, there's a ton to talk about none the less! The PHP git server hack, the OpenSSL vulnerabilities, turns out the spectre mitigations can be mitigated? I'm sure more stuff will come up as well.. As usual drinks and refreshments aren't being provided as this is a virtual meeting.. But soon.. so soon I hope we'll all be able to get together safely. Thanks for being patient and coming to the meetings, I appreciate it. Tim.

Re: WLUG history - Doug Waud's Home Networking slide deck found!

by Doug Mildram

I read the first dozen+ slides ( real good wording/intro I'd say!) ..then ADD-like, surfed later slides and found a minor gem in slide30 so I'll type it back here if I may, just for fun : (Networking) Addressing and Networks (review exam :) What address/addresses represent a network and which a host (assume a netmask of 255.255.255.0) a) 192.168.1.35 b) 192.168.7.12 c) 192.168.3.0 d) 192.168.0.255 e) 192.168.0.0 ANSWER: ( network: c,e ) ( host: a,b ) d) is neither, it is the broadcast address for network e Notice how it is natural to refer to that network by its addr 192.168.0.0 Incidentally, that term "host". It simply means computer. You run into it alot when you are setting up ip addresses. (end of slide 30). ============== dmildram,static> those were the days. Mask? What Mask?

I thought I had been to every WLUG meeting back then. Memories fade. I am trying to remember when I went to Mexico...I am pretty sure I was there several times. At the time I was sure I would remember every detail forever, but now I can't recall what year it was. It might have been 2001. > So I updated the WLUG website's Archive section [1] with the slides: > Home Networking (March 2001) Great job of cyber-archeology! I checked it out. It's 80 slides!! That's not a talk; It's at least four talks. I could not have forgotten all that---must not have been there. It's already proven useful in a way redeems WLUG. After moving ethernet cables around to do jit.sw/WlugMA last Thursday, I discovered I had broken another one of those stupid little plastic latch pins on the end plug. I bought a bag of a dozen at Stark electronics about the time of Doug's talk two decades ago. I am down to just three of them. Stark is long gone; where can I get more? I thought of Google, but I could not remember what the plugs were called. After paging quickly through a few slides, there was the answer! They are called RJ-45 plugs and you can buy them through Amazon. They come in bags of 100, which is excessive, but not too expensive; ($10-15). I suppose I will get a bag. That's more than a liftime supply. In a couple more decades you will be able to pick up about 90 of them _real_ cheap at the estate sale, or free from the dumpster. -- Keith

Linux video edit SW : OpenShot is cool ! and.... AppImages

by Doug Mildram

doug> Pardon my non-meeting-attendance all but 1? month since 2020...anyways, (new fun thing or things I got to learn, below) Mostly this email is a Fun/FYI, but I suspect OpenShot could be popular and maybe some of you use it,etc and maybe even one/some of you are dabbling,etc at video editing. Myself, barely so far. TMI Since a friend (for sister's anniversary) wanted to create a slideshow+music ( MP4, say ) I discovered how easy that is on Linux lately (googling offers ~10 or Top Ten choices of SW). And since I put linux on this friend's desktop, it's a great match and way to teach/learn. (gawd, these life-story-in-pictures quests sure can make a camera-bound picture owner/taker have to cope w their mess of jpegs in cellphone) DRUM ROLL: I only tried one offering for video editing, and scored. .......................chose one that some review(s?) said is most user friendly. It (OpenShot) seems great, for my too-simple needs (slideshow of static pics, adding music/mp3) and can obviously do so much more. Output and input choices have huge lists (eg AVI,MP4 variants,etc for output..... you generate/export to). SO ANOTHER THING i learned doing this is: There's a release/package thing I wasnt aware of ... ....seems a too-easy alternate, in favor of pkgs/release-dependent installs/updates. IT IS CALLED an App Image and it really appears to me to be THIS SIMPLE: a) You download one big file, eg for OpenShot a 130-140mb one-executable file that they name OpenShot-v2.5.1-x86_64.AppImage , you can get from https://www.openshot.org/download/ .....which says......... b) AppImage requires no installation. Just download, make executable, and run. doug> Correct, it doesn't unzip anything, and the one executable "fits all". Wow! I will admit that (on my Mint desktop) the first time I run it (as me/plain-user), the GUI intro/setup dialog/window does ask me Yes/No ? for some question about creating something for?on? the Desktop, and I said YES and I did not get anything added to my ~/Desktop. But who cares? More fun anyways to launch it from a terminal and watch the stdout as you run the GUI. p.s. it DOES save PROJECT (not output/export result, but your per-video project setups) in your linux homedir under ~/.openshot_qt/ ...mine looks like: doug0@host:IN_MY_HOMEDIR:~$ ll .openshot_qt/ drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 transitions drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 profiles drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 preview-cache drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 presets drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 assets drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:17 cache -rw-rw-r-- 1 doug0 doug0 1453 Feb 27 15:57 libopenshot.log drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 title drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 thumbnail drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 blender drwxr-xr-x 30 doug0 doug0 4096 Feb 28 10:15 .. drwxrwxr-x 2 doug0 doug0 4096 Feb 28 10:39 recovery drwxrwxr-x 12 doug0 doug0 4096 Feb 28 10:43 . -rw-rw-r-- 1 doug0 doug0 17352 Feb 28 10:43 openshot.settings -rw-rw-r-- 1 doug0 doug0 1774732 Feb 28 10:43 openshot-qt.log Around 4mb of setup for (so far my only) 66mb MP4 mini-video of PICS w/ 6min of music, the MP4 I exported elsewhere.
