“Lookalike” Warnings in Google Chrome

I recently started hosting a website and didn’t realize it was throwing the error below in Chrome.

The site you just tried to visit looks fake. Attackers sometimes mimic sites by making small, hard-to-see changes to the URL.

After a lot of googling, I finally found an answer on how to get rid of it. I just started the process and will update the post later to see if it worked.

Unraid – Unmountable: Volume not encrypted

So I got this error on my Unraid server for a drive, “Unmountable: Volume not encrypted” for a drive I had used on another server. There was nothing on the drive I wanted so I just wanted to overwrite or format it.

Finally found a link to just overwrite the filesystem.

mkfs.ext4 /dev/sXXX

All of my RAM is not showing up in Unraid

So I bought some RAM recently in one of those bins on clearance because it was opened, etc. I installed it with another two sticks I already had. All four sticks are DDR4, of course, but the old ones were 2x8GB 26666, and the new ones are 2×16 GB 3200. Unraid would only show 16GB usable rather than the 48GB. Unraid did notice them, but they were unable to be used.

After some googling which didn’t get me anywhere, I decided to remove all the sticks and just use the new ones in A2 and B2. Well, now Unraid shows 32GB of RAM usable. So next, I put in the other two sticks in A1 and B1. Boom!!! Now it can use all 48GB. I assume it has to do with a mismatch in either speed or capacity.

traefik v3 example with uptime-kuma

Here is an example of Traefik, using Uptime-Kuma as an example with a domain for it plus using letsencrypt to secure the domain. We also redirect HTTP to HTTPS.

The Traefik dashboard is not secure, so please implement security or a firewall.

This is just an example.

tls: failed to verify certificate: x509: certificate signed by unknown authority

In building a docker image for a Go application using the Apline image, I kept getting this error “tls: failed to verify certificate: x509: certificate signed by unknown authority”. I thought it was something with the code I was writing, but it had to do with the docker image.

Adding this to your Dockerfile should fix the problem. The problem is that the docker container doesn’t have the necessary certs to validate the connection. You might also get around this issue by adding the “ca-certificates” package to the image, but I didn’t try that.

COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

or (depends on how your building your image)

COPY /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

Install dotnet core on Ubuntu 22.04

These are the steps I used to install dotnet core on Ubuntu 22.04, both the SDK and the runtime.

apt update
apt install -y apt-transport-https
wget -O packages-microsoft-prod.deb
dpkg -i packages-microsoft-prod.deb
rm packages-microsoft-prod.deb
apt update
apt install -y dotnet-sdk-7.0
apt update
apt install -y aspnetcore-runtime-7.0

To verify installation run the following commands. If the below doesn’t work try to open a new ssh session or terminal.

dotnet --list-runtimes

Microsoft.AspNetCore.App 7.0.2 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 7.0.2 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

dotnet --list-sdks

7.0.102 [/usr/share/dotnet/sdk]

If you tried previously to install version 7.0 make sure you remove/purge the old version from the system. Something like below.

apt remove --purge dotnet-sdk-6.0 dotnet-runtime-6.0
apt auto-remove

Also maybe delete the .dotnet folder in your home directory.

Updated to MacBook Air M1

Recently updated to a MacBook Ari M1. I’ve never been a fan of Apple products but I found it on sale and I was doing more work with Linux, Golang, and Docker so this met my needs. It was either this or find a good laptop for Linux.

Please visit my Mac page for more information on apps I’ve started to used for development.
