A quick morning updating the Minecraft server that’s there for private play for the boy.
Ubuntu updates on Azure are actually painless. Minecraft jar update took a few moments.
Happy, patched and back to letting the boy play with his friends.
There are some cool Minecraft 1.13 world seeds here btw https://mine.guide/tutorials/best-seeds-for-minecraft-1-13/
A work in progress. Some notes.
- Certbot does not run on SLES 12 (GA, SPx)
- Dehydrated script works well
- Documentation is patchy
Dehydrated, install RPM from http://ftp.gwdg.de/pub/opensuse/distribution/leap/42.3/repo/oss/suse/noarch/dehydrated-0.4.0-1.1.noarch.rpm
- How, what, when
- Setting up cron for renewal
- Email for renewals
Dehydrated: a bash client for Let’s Encrypt
I’ve been bitten multiple times with the SLES service pack upgrade routine – with Red Carpet Enterprise (ouch – that’s a long time ago) and all of the various permutations of update tooling since.
Happy to say that SLES 12 SP1 to SLES 12 SP3 was zero fuss, fast and efficient. Less than five minutes per server on Azure and around 30 seconds of planned outage.
Good job SUSE team!
Woke up to a whole pile of uptime alarms flagging that various websites were not “up” and responding. Azure, Jetpack, Cloudflare – something was clearly wrong.
As you can see from the Apache access logs – hundreds of thousands of hits per minute from the same IP address range – 185.188.204.x
Easy fix to create a deny rule in Azure to block this. I don’t think CloudFlare was touching it.
Watching the logs for this now.
AH00060: seg fault or similar nasty error detected in the parent process
Since I wrote this post (a long, long time ago) – Office 365 now adds support for creating a trusted connector between your Linux/postfix environment and Office 365.
Much, much easier than before.
So as a reminder for me next time:
SASL for username/password
- Postfix main.cf settings
- Set up Office 365 connector and trusted IP end point
Sometimes life is not about technology.
Tumble dryer stopped heating – so take it apart, realise thermal fuse is blown. Clean all of the dust and lint out – reassemble – it works for a few minutes.
Repeat and rinse. This time replace thermal fuse, thermostat and heating element. Same again.
Third time run the vent pipe cleaner up the pipe – and there’s a birds nest in the vent pipe. Desiccated dead bird and all.
Moral of the story – tumble dryer problems – always clean and clean the vent just to be extra sure.
Switched 12 year old Pentium II to a Pentium Core 2 for the firewall box.
Also moved from spinning disk to SSD – and it’s running a lot cooler.
Some notes for later.
App Service Editor is incredible.
Uploading webfonts (woff/woff2) requires that wp-config.php has
set for the short time.
Serving woff/woff2 fonts requires that MIME types are put in place.
Add this to web.config under system.webserver. https://blogs.iis.net/richma/adding-mime-types-to-your-windows-azure-web-site
<mimeMap fileExtension=”.woff” mimeType=”application/x-font-woff” />
<mimeMap fileExtension=”.woff2″ mimeType=”application/x-font-woff2″ />
