New article: My Personal Backup Strategy

Feedback is welcome!

#backup #borg #syncthing

I've been a little bit inactive. Trying to change it again. Most recent article.

Set up new #FreshRSS instance for now. I want to read more and stay up to date on certain topics and I figured I could give RSS another chance. Stays invite-only for now, but feel free to hit me up if you want to have an account.

Focus on decoding unknown strings.

Not gonna lie, wasn't that fun. Learned a lot, but felt lost multiple times. Probably gets better over time.

Doing some rooms on TryHackMe. Decided to create a write up of one room. Have to work on the format, but it should be fine for now.

Feedback is welcome!

I think I've never share one of my favorite articles with you.

Creating this was great and it has been a great resource ever since. I use SSH tunnel a lot in troubleshooting sessions and security demonstrations.

I am pleased to announce the launch of: forum.ittavern.com

More information can be found in this thread, but in short I miss the forum culture and want to create an open-minded and sustainable community.

I welcome you and look forward to great discussions.

I am happy to share with you the new design of my blog.

New logo, new thumbnails, lots of CSS changes and everything is now hosted in a German DC.

The goal was to create a clean design and reduce the loading time even further.

Feedback is welcome.

Sending files over the internet. Been a pain in the past and I finally decided to host my own instance. It should be 'production' ready, but let me know if you encounter any problems.

A quick & dirty solution that is available on most Linux hosts.

I've decided to self-host yet another service. This time it is NTFY. Simple HTTP based push notifications for your devices.

https://ntfy.brrl.net/

Feel free to use it. Feedback is welcome.

I use it to notify me about successful logins on one of my servers, failed backups, results of cron jobs and so on. One simple HTTP request is all you need.

Sometimes I just need a simple whiteboard for troubleshooting or brainstorming sessions. I've decided to self-host a whiteboard with collaboration function. I am going to give whitebophir a try.

Feel free to use it too!

Not optimal for permanent boards as I plan to reset it once a month (not sure yet).

Rsync is one of my most used tools and I am happy to share this guide with you. I've learned a lot doing the research and I hope to share some tipps with you.

I've added a status page with #uptimekuma. I want to get used to it for now. It is currently running on the same server as the rest of the services, which is not optimal. Additionally adding some more sensors at some point.

Just created an overview of the services I host.

I've decided to add an email newsletter to my blog. It is still 'work in progress', but I make progress and the first 'issue' will be sent next Monday.

GDPR-compliant, no tracking, lightweight, and nothing special.

I am happy to share my revised SSH server hardening guide.

Feedback is very welcome.

I've created a new article about Port Knocking in preparation of my rework of the SSH Hardening guide.

I'd like to hear your opinion about port knocking.

haven't shared my backup guide here yet - your feedback would be greatly appreciated

Not sure if there is any activity on Lemmy. Let's find out.
