So far I printed out a 2x4 base plate and a couple smaller containers. I love the idea that the system is totally open and there are step files available so you can expand on it. between copious amounts of ikea skadis pegboard and my tool chest I think I can organize my tools in a way where I can adhere to the Adam Savage rule of first retrieval. Since we have a meeting this Thursday, this can be yet something else to talk about. Tim.

I've been following the gridfinity saga for some time now. There are actually a lot more designs available on some of the 3d print sharing sites too. There are also a few other projects with the same concept, I've also looked at hexagon based one. If I could just get my z-axis on my 3d printer stable maybe I could actually print some.

Re: I need advice on a new ISP

by John Stoffel

Hi Keith, I've been mulling over this email from you all week and trying to work up a reply that will help solve your issues. Unfortunately, I think we're talking about two seperate but related issues here. And I honestly think that maybe having one or more of us come to your house would be a quicker solution here. Long long rambling email to follow.... -------------------------------------- internet at home -------------------------------------- First off, you want to get faster/better/cheaper internet working at your house, since the old provider to dumping you. At this point, I think you're options are cable modem. Now you have a whole bundle of wires you need to check over. But remember that you only really care about the wire coming in from the street, since the rest of them are just feeds to different rooms/locations inside the house. Since you do not have TV setup, this makes things simpler. Just disconnect everything. Then, hook the cable modem upto the one wire coming in from the street and give it power. If you get a single, the lights will come up and give you some status and let you know if you found the right wire. In my house I have Charter Spectrum and the wire comes in and goes through a splitter, and the cable modem gets the first and best signal port from my four way splitter. The rest go to various TV cable drops in rooms around the house. So once you have signal and you can get on the internet, that issue is mostly solved. Running ethernet or Wifi through the rest of the house is just icing on the cake. -------------------------------------- firewalls and wifi - lots to discuss! -------------------------------------- And of course running your own firewall and just using their cable modem as a modem is another wrinkle!! I tend to run my own firewall and wifi on seperate systems here at home. Charter will send you a combined box, but it's never clear how much control you really have over it. I'm going to skip over all this right now since I'm assuming Charter sent you (or will send you) a combined unit to do all this. -------------------------------------- email from/to your own domains -------------------------------------- The big issue here is that nowdays Charter and other big ISPs do NOT like people sending or even getting email on port 25. Mostly the sending. So they usually tend to block outgoing port 25 traffic. They might also not be totally happy with web services, but that's another issue. So this is where having a VPS (Virtual Private Server) in the cloud running linux is a solution. But!!! You need to change how email goes out from your internal linux systems. I can help since I have this exact same setup. My main system (quad) runs postfix and knows to forward all outgoing emails to mail.stoffel.org over port 587, the submission port. I have setup a username/password combination for postfix as a whole to use to login and send emails. mail.stoffel.org is a VPS running Debian (I think) out in Linode. Not perfect, but not terrible. I have postfix/dovecot/spamassin up there and it's costs me something like $9/mon for a one CPU/1gb of RAM server which I completely manage. This is where my limited external web server is, where my MX records for stoffel.org point to, and where I send emails from to the outside world. Works quite well. But there are some problems at times with places like charter.net blocking my IP since Linode does sometimes host spammers, and so the big big guys tend to block not by IP, but by entire subnet blocks. There might be other web providers out there, at varying levels of cost and performance that you can use. I used to use Digital Ocean, but their subnet blocks have such a horrible reputation that I moved to Linode. And I was still blocked by charter until I found an internal contact who was able to open up my single IP to allow incoming email. Whew. Anyway, I'd be happy to come on over and look at your systems and help you out. Just let me know! >>>>> "Keith" == Keith Wright via WLUG <wlug(a)lists.wlug.org> writes: > Kevin Stratton via WLUG <wlug(a)lists.wlug.org> writes: >> I am not sure how helpful this is, The Comcast technician that >> installed my cable modem insisted that all the splitters be removed > It might be very helpful.

Re: I need advice on a new ISP

by kevin.paetzold

If you disconnect all the cables so that none of them are connected to anything... you can short out the cables in the rooms one at a time and then use an OHM meter to look for the cable that is shorted.i used this to determine which cable went to which room. OrPut a small DC voltage (like with a 9-volt battery) on a cable and then go to the other end and look for which one has 9 volts on it.Since you are looking for the input I guess use process of elimination. -------- Original message --------From: Keith Wright via WLUG <wlug(a)lists.wlug.org> Date: 9/7/23 14:21 (GMT-05:00) To: Worcester Linux Users' Group General Discussion <wlug(a)lists.wlug.org> Cc: wlug(a)lists.wlug.org, kstratton(a)fastmail.us, Keith Wright <kwright(a)keithdiane.us> Subject: [WLUG] Re: I need advice on a new ISP Kevin Stratton via WLUG <wlug(a)lists.wlug.org> writes:> I am not sure how helpful this is, The Comcast technician that> installed my cable modem insisted that all the splitters be removedIt might be very helpful.

Re: I need advice on a new ISP

by kevin.paetzold

I have cable at two houses. One is on the cape (Comcast). the other one is a local municipal cable systemComcast claimed there was too much Ingress coming from my house. They came into my house and pretty much replaced every piece of cable that I had outside of the walls. They also installed some kind of isolator amplifier unit (that requires power that I had to put on a UPS).I believe on the Comcast website for your account you can actually see how much noise they think you produce.On the municipal system I had an issue where my cable boxes were not working right. The first thing the guy did is removed every filter, splitter, trap and other doodad that previous technicians had put over 30 plus years.And then I got rid of all my cable channels at both houses :-) -------- Original message --------From: Kevin Stratton via WLUG <wlug(a)lists.wlug.org> Date: 9/6/23 08:38 (GMT-05:00) To: Worcester Linux Users' Group General Discussion <wlug(a)lists.wlug.org> Cc: Keith Wright <kwright(a)keithdiane.us>, Kevin Stratton <kstratton(a)fastmail.us> Subject: [WLUG] Re: I need advice on a new ISP I am not sure how helpful this is, The Comcast technician that installed my cable modem insisted that all the splitters be removed so that there is only one cable (with connectors) from the cable going into the house to the modem.

Re: I need advice on a new ISP

Keith, I love the term bafflegab, it's the truth. Every cloud provider has preferred names for things that should just be named sensibly. This doc gives a good overview on how to setup a web server. https://docs.oracle.com/en/learn/lab_compute_instance/index.html#connect-to… Basically you create a VM "compute" in their parlance, deploy your favorite web server, copy your HTML over, DNS shenanigans and away you go. you'll also need to modify the security settings on the private network that your VM is running on to give it a public IP and allow port 80 in. You're not going to need a load balancer, etc.. Tim.
