Just spent five hours troubleshooting my home network - tried everything from checking cables to reconfiguring routers and switches. Turned out the fix was the classic: turn it off and back on again.

Honestly, the ultimate IT hack never gets old. 😂

Lesson learned: patience and persistence pay off, but sometimes it’s the simplest solution that wins.

Anyone else have those epic “wasted hours for a reboot” stories? Share ‘em!

Just Blame the Network.
It’s the unspoken rule. Something goes wrong? Must be the network. 🤷‍♂️

My #Protectli internet #router died after 8 years of service. #RIP.

It took 3 days for a new unit to arrive. After much struggle, I have recovered my old settings and my #network (including this #Mastodon server) is back.

Note to self…

- 802.1Q VLANs… don't just check what untagged VLAN members, check the PVID too.
- UniFi U6-LRs don't work if the Ethernet cable is sitting 5mm out of the socket

On the plus side, my noise floor on #80m and #40m hasn't jumped back through the stratosphere when I plugged that cable back in.

A question for my netowrk/sys admin friends. I want to create a nextcloud server on an old laptop at home. Since this sits behind my router, I am wondering how I can access it from the outside. I suppose this is a big chunk of a network admin's competence, so I am not aiming to be proficient at it by simply reading up. However, are there free resources that will help me accomplish what I want ? I want to be as safe as possible to external attacks.

Amazing how the business support at these ISPs is about as good as warm body tier 1. You haven't heard an update from me because the last message I sent you was "hey nobody has provided a real update, we don't have a downlink, fix your shit"

6x6mbps being the minimum viable to run a retail environment in "good" condition is wild to me #networkadmin #networkengineer

Random Spam in my work email:

Sure! If you take it and smack me in the forehead with it. Like a baby.

Do not disable IPv6.
Manage IPv6.
But do not disable it.

If you're a network architect, network engineer, or network administrator:
Master IPv6.

If you're not up to speed on IPv6, you're late, and it's time to wrap your arms around it.

Make it a personal and professional priority.

I used to have a saying in my help desk days: "Do it, note it!"

On the help desk, it means that if you do something, anything, put it in a note... updated httpd.conf, applied a PHP module update, etc. and I like to use it even in my professional, non-help desk life now.

If you do something cool like install Mastodon, patch a bug in an open source project, create your own software, update your home lab etc., you should blog about it and share your notes!

Sometime this week 📆 (what's left of it) I will be trying out to see if I can recover my Mastodon :mastodon: instance from a failed :linux: server. Changing hosts :oracle: completely. Why you ask? Just to see if I can do it in a timely manner.

@RouxJ I get errors like that sometimes too! I would also like to know what the issue might be.
