IPv6 Is a Total Nightmare — This is Why

2020-09-06 26 min read Networking Rants Teknikal_Domain Unable to load comment count

So this is just going to be a total rant. IPv6 is, in theory, a solution to many things, including the dwindling IPv4 address space. IPv6 was a draft in 1997(!), and became a real Internet Standard in 2017. And, quite frankly, it’s one of those things that just adds too much hassle for not enough benefit.

Or, how I learned to stop worrying and love the BPDUs.

Spanning Tree Protocol, as mentioned previously, is a protocol used by switches to build out a loop-free logical topology of an Ethernet network. The protocol itself is built off of a concept called, well, a spanning tree.

How does this work? Well, that’s what I’m here to explain.

Yeah I figure why not, at the same time that I’m replacing another key piece of network infrastructure, I might as well just replace the (second) most important piece, right? So cue the music, because…

Now, this is a story, all about how my life network got flipped, turned upside down, and I’d like to take a minute, just sit right there, I’ll tell you how I became the prince of a town called Bel Air the owner of a… just… just cut the music. Let’s begin.

So if I said the words “Lightweight Directory Access Protocol”, do you feel my pain? if you don’t, keep reading. Otherwise, you likely know exactly where this is going to be going.

And for the record: this is something that I’ve struggled with for about 8 months, and I think it’s getting close to the point where I really should just give up… but I won’t.

If that title isn’t a dead giveaway, I’m not happy. But yet I will somehow manage to vent my frustrations and explain something at the same time. Today: SNMP, or, “How to gather lots of stats on remote machines,” or, “Because you thought CVS was hard to wrap your head around.”

Adventures in HAProxy

For those of you that do not know, HAProxy is an amazing piece of kit that can proxy HTTP and arbitrary TCP connections. It’s also so customizable that I’m practically using it as my main entry point to my network, and do indeed refer to it internally as the “border gateway.” With two exceptions (SSH and SMTP, more on that later), everything that comes into the TD-StorageBay network, yes, that includes this site too, passes through that one process. However, HA cannot do everything… and I feel that I’m pushing its limits. Not in the “sheer workload” sense, no, I am way far off from that. I mean in the old Mythbusters style “using things in ways for which they were never intended” manner.
