Everyone (okay, everyone this is relevant to) knows what SMTP is, the standard for mail transfer. It’s even in the name, Simple Mail Transfer Protocol, which is how mail servers have been sending mail to other mail servers since… a while. Well, fun fact, there’s another protocol that accomplishes the same goal: QMQP, the Quick Mail Queuing Protocol.Continue reading
See also: managing to mildly destroy a network for 5 minutes while the switch has an anxious breakdown. Unfortunately, my reliable Dell PowerConnect switch has, well… it failed (kinda), and I was looking for an excuse to upgrade switches, so… I did. Admittedly, my impressions of Netgear kit aren’t the highest, but, hey, this switch is actually stupidly good for the price (I paid).
Oh, yeah, I also replaced the UPS since the entire network was offline anyways.Continue reading
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.Continue reading
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.Continue reading
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.
Note: Not sponsored. Just excited.
So, fun fact, I run Pi-hole on my network as a relatively easy set-and-forget ad-block. For a while, this has been, and please stow your pitchforks, a VM on the main hypervisor. As of now… it’s that thing up there. Pi-hole’s resource requirements are so low that no matter what I assign that VM, I’m wasting something somewhere. Besides, I have plenty of those little machines, so why not?Continue reading
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.Continue reading
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.”Continue reading
