Purchased Switch and 10 GbE adapter

May 7th, 2018

Happy anniversary blog! Last night I purchased an 8 port 10 GbE switch (maker HPE, american) and a 10 GbE Intel X550-T2 network adapter. I'll be attaching these to beta my workstation which will become a router with vlans on the 10 GbE adapter. I'll also make beta my backup host as my current backup host theta does not wake properly (even on RTC wake), and it's better this way anyhow. The equipment purchased was rather expensive but I was in need for ports in the home office. This satisfies my need. Uranus my 6 port router will go into the hallway and replace eta and gamma and I'll make some electricity savings there. Everything is working out...

Happy Anniversary!

May 6th, 2018

Tomorrow is the blogs ninth birthday (9 years). This is the oldest article I could find. Also the 7th anniversary I said something you can read it here. Notice the hyperlinks have changed on a lot of articles since I rewrote this blog to BCHS, so you may enounter broken hyperlinks. I'm still debating whether I should update those. For now it's time to party. Here is a cup o' tea to ya centroid.eu blog!

Added SSHFP utility to dddctl, while there fixed signing sshfp records

May 5th, 2018

I have added a "sshfp" mode for dddctl which makes use of ssh-keygen -r. This is the output of it:

beta$ dddctl sshfp beta.centroid.eu
  beta.centroid.eu.,sshfp,3600,1,1,"bd1233ca6586a3033ac5d90209a7e4c36269b83f"
  beta.centroid.eu.,sshfp,3600,1,2,"ad389bc08427c82f96d15aa2bf28017f70bee17ab441d641778b13b179233e62"
  ...

I find this useful others may not, but i do. The canonicalization of RR's for the signing was in the wrong order and I had to fix that last night. It was a bit of a debug. And perhaps more sign types need the fix I found than just sshfp_sign(), we'll see.

This may change soon as I've decided I need more ports. Since I lost venus (router) I'm short for 12 RJ45 gig ethernet ports. I'm going to wait a while until OpenBSD makes the vpn offload code for octeon stable and then I'm going to buy a 10 GbE switch (probably a Ubiquiti Networks one) and place that in my office, where uranus will go in the hallway and eta in my office. I wasn't going to do that until 2020 but I have a need for more ports now and I don't want to mis-invest. We'll see.

Bavaria's Polizeiaufgabengesetz (PAG)

May 3rd, 2018

Dear reader, I want to make you aware of the Bavarian (a state in Germany) police law that is about to enter if we vote for the CSU or in other words it's leader Markus Söder. The law allows Bavarian police to enter cloud computers of Bavarian citizens and conduct sabotage, spy on the users, embed a trojan etc etc. This is mega bad, and we're facing a possible police state if this law makes it. An article by campact.de which I signed as well sums it up nicely so I want to let you in on it. It's here (german). I don't know why we're seeing all these acts by government to inhibit the citizens rights but it is a global phenomenon. We must act in all democratic countries to fight by democratic means these onslaughts. I already said an article prior to this about Bavaria's Psychiatric law that I won't be voting for the CSU as this crap can't stand. I stand to this.

Cancelled chi.goldflipper.de

May 3rd, 2018

I just cancelled this VPS that I got close to 7 years ago at hetzner online. It was originally called io.solarscale.de, but I renamed it about a year ago when I got goldflipper.de domain. I'm getting a better deal at the same provider with a new vps.

I have just refined the search

May 2nd, 2018

You may have noticed that the "Keyword Search" is gone. Instead I have a "Search" where you can use an AND or an OR search term with up to 16 keywords. So as an example you can search this blog with:

"firstname initial. lastname" OR "firstname initial. lastname", and it will list any articles that have any of these exact search terms (case insensitive)
something AND something, and if both words appear in an article it will be listed
and so on

I'm very glad to make this happen, the code is ugly but it works.

I have removed PHP from my webserver (for the time being)

April 30th, 2018

Now that my blog is based off C I have removed PHP from this system. There was three other .php files left that I made static content files. This is by some seen as a win. I'm not so sure but willing to see it go through.

A newly written blog, happy anniversary!

April 30th, 2018

Tomorrow is may, and that means that this blog is turning nine (9) years old. For the anniversary I have rewritten this blog from PHP to the C programming language in record time. I think I spent less than 24 hours coding on this. The new blog software is now running and I'm ironing out the bugs as I see them.

Please update your RSS if you've been using RSS. I don't think the url for this will change any time soon so you should be getting the last 10 articles in the RSS. I just renamed my RSS feed to have the history and added the new feed by entering the URL into thunderbird.

Enjoy, and happy may day!
