Reminder: WLUG Meeting tonight: Topic ProxMox / Turning Pi 2
by Tim Keller 16 Feb '24

16 Feb '24

Hey Everybody! We've got a meeting tonight! Time: 7pm Date: February 8th, 2024 Location: Technocopia, 44 Portland St. Worcester MA Virtual Location: https://meet.jit.si/WlugMA For a topics, We've got two. Topic #1: Turing Pi 2 hardware Wlug member Zori Babroudi recently bought a Turning Pi 2 and a bunch of Pi and Rocks compute modules. Currently, it's a work in progress, but eventually once things are totally working on it, I'd like to show it off in its full glory. But in the meantime, we can marvel at the hardware. Ultimately, the plan is to run k8s on it and do some LLM based AI stuff as well. Topic #2: ProxMox With BroadCom's purchase and destruction of VMware, many of us are scrambling to look for alternatives to VMware Esxi. One great contender is ProxMox. It's a debian based distro that's focused on providing a great interface to manage vms running on kvm. It also has great support for video card pass through (something I know Brandon is *very* interested in). I've got a 3 node proxmox cluster that I will show off. John Stoffel has also been experimenting with it as well so both of us can talk about the good/bad/ugly of it. As usual, the conversation will be lively and focused around linux, FOSS, fair use and who knows what! Afterwards we'll head off for some dinner and keep the conversation going! I hope to see you there! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Firewalld/iptables/nftables question
by Patrick McEvilly 08 Feb '24

08 Feb '24

All First off, I’m in way over my head. $dayjob we have a redhat 8 box. We are looking to take in syslog messages and sent them out to one/two different IP addresses. We tried using https://github.com/sleinen/samplicator and while it works perfectly and a one banana job to setup, we seem to be dropping a significant amount of traffic on the box. At least 10% of the logs are missing and we have not loaded up the system yet. We tuned out the network buffers and added 25MB of memory without any improvement. https://github.com/sleinen/samplicator/issues/72 Seems at a high rate of logs (which I think we would fall under) there seems to be some issues. We looked at this option - https://zapier.com/engineering/iptables-replication/ Redhat 8 seems to be using firewalld and backended with nfttables so we can’t directly use this method so we tried this. firewall-cmd --permanent --direct --add-rule ipv4 mangle PREROUTING 0 -i ens192 -p udp --dport 514 -j TEE --gateway 127.0.0.1 firewall-cmd --permanent --direct --add-rule ipv4 nat PREROUTING 1 -i ens192 -p udp --dport 514 -j DNAT --to-destination 10.137.241.79:514 firewall-cmd –reload With no luck, packets are not getting sent to 10.137.241.79. When it works with samplicator this is what we get. 11:53:04.382233 IP 10.240.136.4.24277 > 10.240.1.1.syslog: SYSLOG local7.notice, length: 670 11:53:04.382408 IP 10.240.136.4.24277 > 10.137.241.79.syslog: SYSLOG local7.notice, length: 697 sysctl net.ipv4.ip_forward net.ipv4.ip_forward = 1 IP Forwarding is enabled. I’m not at all familiar with any of this and cutting and pasting from the internet and chatgpt has come up empty. Anyone have any suggestions on what we are doing wrong? Patrick

3 million smart toothbrushes were just used in a DDoS attack. Really
by Tim Keller 07 Feb '24

07 Feb '24

My favorite part of the story.. "While the details are scarce, we know that the compromised toothbrushes were running Java." We are officially living in the dumbest time line. My only hope is that the servers at the far end of that DDOS attack at least had a minty smell to them..

Proxmox!
by Tim Keller 26 Jan '24

26 Jan '24

Hey Gang, As many of us have been watching the news, BroadCom has been gleefully destroying vmware at scale. I've been exploring FOSS replacements for esxi and one of those is Proxmox. It looks pretty cool and has a pretty awesome set of features. Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

I just bought a Pi5.. we'll see if I actually get it.
by Tim Keller 18 Jan '24

18 Jan '24

They say estimated delivery of Jan 9th - Jan 11th.. So, who knows.. I bought the 4GB model, so it should be functional as a desktop, my plan is to experiment with it as a daily drivers. Beyond that, what do people think would be a good benchmark to experiment with? Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Hey Everybody, Happy New Year! Thanks for sticking with WLUG! It's been a year of change and challenges. We found ourselves a new home at Technocopia and make some new friends along the way. This is going to be another amazing year of talks and demos, lively conversations and general geeking out on all things. I look forward to many more WLUG meetings to come.

SMTP 25 license plate
by Michael Voorhis 03 Jan '24

03 Jan '24

About a week ago while commuting I was trapped in gridlock behind another vehicle with the license plate "SMTP 25." I think in the past I have seen also a license plate "RTFM" but that was a long time ago. It seemed to me at the time that the owner of the SMTP-vehicle would probably be on this mailing list. --MCV.
