We talk about QoS (Quality of Service)/rate-limiting and optimizing your network traffic before it hits The Tubes™.
Just the Tip
- F5 has a pretty serious vuln, so patch your shit.
Starts at 15m31s.
- A way to artificially manipulate network traffic to ensure the priority of other traffic.
- Jthan wanted to know why his network went to shit whenever he’d start uploading files.
- “There’s no distinction between a ‘corporate/professional’ network and a ‘home’ network.”
- That’s a false dichotomy created by network hardware providers. The true distinction is between well-designed and well-executed networks, and those without a good design and/or execution.
- The latter usually don’t see a level of scale where the distinction is made, and thus any actual difference is just handwaving as “residential networking”.
- I suggested that it’s probably actually queueing/scheduling, which is very likely.
- He’s also using a wireless network, which will affect the throughput of the WAPs’ radio cards.
- But QoS would still perhaps help a little bit. Back on track…
- Quality-of-Services is an IEEE standard, 802.1e (and then rolled into P802.1p).
- There is, of course, a wireless variant, 802.11e.
- QoS theory
- You can use “tc” to implement QoS.
- Speaking generally, on the network you want your downloads to be faster (or more reliable, to be accurate) than uploads. But on a host’s level, you typically want uploads prioritized.
In this segment, Jthan shares with you a little slice of life. The title is a reference to this video. (2m16s in)
Starts at 1h03m55s.
- The juggernaut, bitch.
- A “tacodemon“ (cacodemon) from Doom.
- Shoutout to The Admin Admin Podcast (and that guy).
- I can’t find a source for Paden’s thing about banning install of non-OEM OSes.
- The IP address Paden started rambling off was the beginning of an RFC 3927 address.
- I sometimes refer to “802.1e” as “802.11e” and vice versa, and forget to mention P802.1p. Oops!
- At the beginning of the 15 Clams, I say “30Mbps down”. I should have said “symmetric 15Mbps up” or something, oops.
