Malicious use of QR codes has long been ubiquitous, both in the real world as well as in electronic communication. This is hardly surprising given that a scan of a QR code can lead one to a phishing page as easily as clicking a link in an e-mail.

In yesterday&#;x26;#;39;s podcast, I mentioned “tailsnitch”, a new tool to audit Tailscale configurations. Tailscale is an easy-to-use overlay to Wireguard. It is probably best compared to STUN servers in VoIP in that it allows devices behind NAT to connect directly to each other. Tailscale just helps negotiate the setup, and once the connection is established, data will flow directly between the connected devices. I personally use it to provide remote assistance to family members, and it has worked great for this purpose. Tailscale uses a “Freemium” model. For my use case, I do not need to pay, but if you have multiple users or a large number of devices, you may need to pay a monthly fee. There are also a few features that are only available to paid accounts.

Recently, a new “breed” of IP-based KVM devices has been released. In the past, IP-based KVM devices required dedicated “server-grade” hardware using IPMI. They often cost several $100 per server, and are only available for specific systems that support the respective add-on cards. These cards are usually used to provide “Lights Out” access to servers, allowing a complete reboot and interaction with the pre-boot environment via simple web-based tools. In some cases, these IPMI tools can also be used via various enterprise/data center management tools.

One of my holiday projects was to redo and optimize part of my home network. One of my homelab servers failed in November. I had only thrown&#;x26;#;xc2;&#;x26;#;xa0;the replacement in the rack to get going, but some cleanup was needed. In addition, a lot of other “layer 1” issues had to be fixed by re-crimping some network drops and doing general network hygiene. The dust buny kind hygiene, not so much the critical controls type. After all, I don&#;x26;#;39;t want things to overheat, and it is nice to see all network links syncing properly.
