AS204994, Own IP Space and Anycast

by . Tags: Networking , IPv6 .

So, if you are reading this page, it is being delivered with the magic of Anycast… Well, technically, it was before, since i used Cloudflare, and it still is because of Cloudflare, but also because of my own ASN (As204994), some servers in different locations, and some magic, which i will explain a bit of in this post. This all started late last year when i got my hands on an ASN and a /48 block of IPv6 addresses.

Zerotier and Minio Followup

by . Tags: Networking , IPv6 , HomeLab .

in a previous post, I talked about setting up a distributed S3 like data storage system using Minio and ZeroTier. Well, this week, the ZeroTier guys tweeted about this. Distributed S3 data storage using @minio and #ZeroTier -- https://t.co/MAXTjo3muh — ZeroTier, Inc. (@ZeroTier) May 2, 2017 A few people then started asking questions, and looking for a follow up, so here it is… First, a quick recap. I had 4 machines, all running Linux.

Business Class Broadband… finally here….

by . Tags: Networking , IPv6 , HomeLab .

So, after many (MANY) years messing with dual cable modems, struggling to get them working together, to get websites to even allow me in, having to use hacks and kluges to get it to work at all… I have given up. It has been a struggle getting two modems working properly. Load blanching kind of works… but it’s messy at best. Some sites kick you out every now and again because your IP changes.

double speed Internet Part 8 - Routing Around

[NOTE] This part 8 in a series of posts. The rest can be found here. At the end of my last post I asked the question about routing traffic to different servers based on thier distances, etc… Well, after a bit of messing, i can say it kind of works! here is a quick over view: server in the house has now got multiple OpenVPN connections (2 to Hetzner, 1 to OVH (with a plan to double), 1 to Digital Ocean (again, to be doubled) and i am planning 2 to Azure as well).

double speed Internet Part 7 - ECMP (kind of)

[NOTE] This part 7 in a series of posts. The rest can be found here. In the last post I mentioned I am now using Hetzner for hosting a dedicated box. Thats still live, and going well. I have a /29 IP range (6 usable) and also 2 other IPs. So far, so good… But because i was using a Socks Server, I was not fully able to use the /29 ips… I use something like as follows:

[NOTE] This part 6 in a series of posts. The rest can be found here. Its been a while, since I posted, and there are some, well, pretty major changes since the last time… Lets start are the beginning. Last time I was using Digital Ocean for my hosting provider. I was using their $20 a month server (2 cores, 2GB RAM, 40GB SSD, 3TB transfer), and it was all good… But I noticed that every now and again I would need to reboot the box.

2 Cable Modems = Double Speed? Part 4

[NOTE] This part 4 in a series of posts. The rest can be found here. So, this week I went in a completely different direction that I have been thinking recently… So, the basic theory is as follows: I am still using MPTCP kernels on both upstream and local machine now have 2 P2P UDP OpenVPN tunnels between house and cloud. Example config is here all TCP traffic (bar port 80) that hits the router in house is redirected to RedSocks RedSocks uses a socks server, Dante, as an upstream server on the cloud box since the socks traffic is over TCP (inside the UDP OpenVPN tunnel) it uses MPTCP having socks running, gives me quite the download speed, turning it off does not, hence the following tweet Hmmmm.

2 Cable modems = Double speed? Part 3

[NOTE] This part 3 in a series of posts. The rest can be found here. In Part 1 of this series I explained the why and what I wanted to do for this “project”. In Part 2 I did some basic testing of both MPTCP and MLVPN. I also mentioned trying MMPPP using vtund but it has been a while since I did that testing, and it had not been on bare metal.
