EDIT: I found the following tutorial after posting this (and then finding some sites not resolving properly): https://labzilla.io/blog/force-dns-pihole .... this tutorial better describes the 3 NAT rules that are implemented and detail how they operate. I have seen that these rules operate better than how I have things configured.

Previously, I have setup multiple AdGuard Home instances on my personal network and have all VLAN's pointing to those instances. This works well, like 99% of the time. However, there are times where kids or others have devices (Amazon tablets, Roku TV's, etc) that have external DNS resolvers (like google dns) as a fallback in case there are issues with the local DNS. Now... I literally want to avoid this. Part of this is due to restricting children's access on the Internet, some is due to making sure that everything gets logged. When these devices are permitted to bypass local DNS resolvers, it opens up the Inter

Question for everyone…

Recently I got GeekRoom.Tech fully operational and federating properly. However, before full success, I ran into a lot of issues and at one point had the domain as www.GeekRoom.Tech.

As you can see (here)[https://grafana.lem.rocks/d/edf3gjrxxnocgd/federation-health-activities-behind?orgId=1&var-instance=All&var-remote_instance=geekroom.tech&var-remote_instance=www.geekroom.tech&var-remote_software=All] the www version of the instance still has a bunch of instances trying to publish to it.

What is the best way to resolve that? I assume that those instances are actively trying to push activities but are constantly failing, potentially eating up bandwidth for them.

Hello all, I’m looking to get some icons and header images setup for the GeekRoom.Tech instance and its associated communities.

Would you be willing to create community images and banner images? It’ll help identify the communities when individuals want to post to these communities and helps create a community brand.

If you have some ideas of images or want to donate some images that would help the communities stand out, please feel free to link higher quality images to a comment and I’ll check them out.

Thank you in advance for anyone willing to help contribute!

Images needed: HomeLab icon and banner DataHoarder icon and banner FAQs icon and banner GeekRoomMeta icon and banner New Here icon and banner

I’ve got a site icon, but no banner. If you have other options for those images, I’d be happy to put something up there too!

I’m looking into switching from 1gig Ethernet in the network to at least 2.5gig for my core switch. I’d love to be able to do intervlan routing with a layer 3 switch but am unsure whether it’s worth my time and effort.

Should I instead just setup my OPNsense with LAGG of 3-4x 1gig ports and just continue routing VLAN traffic with it?

I know it’s not optimal, but I’m also looking to do things relatively within budget. I don’t want to spend $500+ on a 2.5/10gig layer 3 switch… especially but if that’s my options I’ll consider it.

Edit: I made my decision. I found the Brocade ICX6610-48P. It ticks almost all the boxes that I’m looking for.

• more than 4x 10gbps SFP+
• layer 3
• has plenty of expansion for both SFP+ ports and for Ethernet ports.

I know that it doesn’t have 2.5/5g speeds natively, but I’m understanding that if I set the SFP ports to 10G but have transceivers that are capable of negotiating 2.5 or 5g speeds. Then it still works. Currently, I’ll continue using 1G sp

I’ve got a few upgrades that I’m looking to do to my homelab and am looking for some suggestions on what to approach first.

I’ve currently got the following mini pcs:

• 2x HP ProDesk 400 G4 i5-8500t, 32gb ddr4)
• 2x HP EliteDesk 800 G3 (i5-7500t, 32gb DDR4)

I’m looking to upgrade these units to 64gb ddr4 as I recently discovered that HP claims only 32gb supported but found there are people running 64gb in these. So that’s what I’d like to move to as well.

Additionally, I don’t use the WiFi cards in these, I run everything hardwired. I have seen some folks changing to a 2.5gb Ethernet adapter that uses the WiFi slot since the flexio port doesn’t support Ethernet in these generations. What adapters are supported?

Administration, moderation, and federation policy for GeekRoom.Tech

This post aims to lay out the rules and principles for how administrators, moderators, and users of GeekRoom.Tech should behave while use the GeekRoom.Tech name, address, and reputation. This is a set of formal rules that all users, admins, and mods must abide by.

Instance rules

This instance (like most others) has a set of rules which are always visible on the sidebar of the front page. All users of this instance are expected to follow these rules in all of their activities, including:

• Community moderation
• Posting
• Commenting

⚠️ Our rules apply even when you’re posting in a community on another instance. For example, this means that you’re not allowed to post advertisement spam using your GeekRoom.Tech account on any other instance (even if that other instance has no rules).

GeekRoom.Tech Federation Policy

As GeekRoom.Tech is a new lemmy instance, we have not seen any de-federation drama yet, but I want to make a point to address the policy of federation and de-federation in one place, prior to any drama that may eventually happen.

I am the head admin of GeekRoom.Tech. I have opened this instance to be a safe haven for all individuals that have a passion for technology, technology-related topics, and even those that just need a safe space to migrate from other websites such as Reddit without fear of shareholders forcing changes due to the need to make company profits.

This policy seeks to address how GeekRoom.Tech approaches de-federation and how we will handle discussions about de-federating from specific instances.

Hello! Just wanted to introduce myself a bit.

I’m a system administrator during the day working with some PITA IBM products, Linux, and related projects as smaller duties.

I’m an avid HomeLabber trying to expand my own skill set but also provide a way for people to engage and have meaningful conversations. During my free time I’m usually tinkering with existing self hosted services or trying to setup new ones to enhance my family’s experience or to make life easier in some fashion.

I have a passion for basically everything technology and learning as much as I can. I realize that as I get older, I’m not picking up on things as fast as I would previously, but I’m going to attribute that to attempting to introduce significantly more complex systems that require more effort, critical thinking, and time to implement.

Two of my most recent successes in my self hosting journey have been getting this Lemmy instance up and running, and also getting VLANs fully functioning in my home netwo

For anyone interested, here’s the Lemmy markdown configuration. As you can see, Lemmy’s website UI supports the full commonmark spec (tutorial / official spec), plus a bunch of extensions. I don’t think anyone’s fully documented these yet, so I’ll try doing so below. Apologies in advance to mobile users, this is probably gonna get ugly (see included image links for how it should look):

• URL autolinking (plaintext URLs automatically turn into links, as recognized by Lemmy... but some may not be autorecognized due to new domain extensions)
• Manually linking URL: [name of link](https://actual.link/) → name of link

Hello! I want to personally welcome you to GeekRoom.Tech. I seek to make this Lemmy instance a fantastic place for anyone and everyone that enjoys technologies of many different kinds.

GeekRoom.Tech is meant to provide a safe haven for individuals to have discussions without fear of censorship and fear of being banned for asking what others believe to be silly questions.

Everyone starts somewhere in their technology journey. I want to be sure that everyone is respectful in their discussions and understands that others may not have the easiest time understanding advanced topics as easily as you.

If you have any questions, please reach out to myself or any other mods or admins for assistance. We seek to enrich your brains and find ways to help you achieve your technological goals!

Over the last year, I have been trying to work through getting VLAN's setup and operational in my Homelab... so that I can not only experiment, but also to start segregating services from PC's and putting things like IOT devices and Guest devices on their own VLANs.

I come to you today, with a working solution for my own homelab. This post is mainly just to discuss the current state of my homelab, but also look for suggestions on how you would make any changes to my layout.
