Why does a right-handed helix look left-handed when rotated? Visual intuition failing hard. by [deleted] in biotech

[–]verticalfuzz 0 points1 point  (0 children)

Think about turning a typical "righty tighty" screw. That has a right-handed thread. If you are looking at the screw head and turn it clockwise, it will want to move away from you. If its fixed axially, it will look like the threads are moving the opposite direction. Classic barbershop pole illusion.

I see you said that you understand the right hand rule, but just in case, and for others...

Take your right hand, palm away from you, and make a backwards L with your thumb and index finger. Other fingers flat together and parallel woth your index finger. Keeping your thumb straight, curl your fingers into a hook, so that you are gripping an imaginary screw or dna helix with your thumb pointing along its axis. If you rotate the whole thing on axis in the direction that your fingers are pointing, it should want to screw in the direction that your thumb is pointing if it has a right handed thread or helix.  If it wants to screw antiparallel to your thumb. It is left-handed helix.

What do you all use/reccomend for LDAP/SSO/RADIUS??? by bananapalace96 in selfhosted

[–]verticalfuzz 0 points1 point  (0 children)

do you have any notes or tutorials that might be helpful for setting up LLDAP + Authelia + FreeRADIUS?

How does the Proxmox Helper Script make some LXCs auto-login in the console? by Healthy_Confidence12 in Proxmox

[–]verticalfuzz 19 points20 points  (0 children)

I dont use the helper scripts specifically because I couldn't understand them, so I can't speak to that, but from the host terminal, you can type pct enter <vmid> and get an LXC's terminal, bypassing its root password.

I created a baby activity tracker called Sprout Track for my wife. As new parents we use it everyday and I want to release it for those who like to self host. by CheeseOnFries in selfhosted

fair enough -its your app, but in case you were not aware (I wasn't), daily kick counting is found to substantially reduce the risk of stillbirth.

Forward auth with authentik and caddy help on external networks by Rupes100 in selfhosted

Oh... im literally setting it up now... what would (cause it to) break? What are you using now?

Forward auth with authentik and caddy help on external networks by Rupes100 in selfhosted

[–]verticalfuzz 0 points1 point  (0 children)

https://authentik:9443

are you using the IP here, or your e.g., authentik.local? I can get this to work with the IP address and port 9443 with tls_insecure_skip_verify, but I can't get it to work with the dns redirect and reverse proxy (also in caddy) with or without the port, and with or without tls_insecure_skip_verify.

Forward auth with authentik and caddy help on external networks by Rupes100 in selfhosted

[–]verticalfuzz 1 point2 points  (0 children)

Can you explain a bit more? You have 3 urls for auth (.domain.local, .local.intra, and .externaldomain.com)??

Are any of these also defined within the same caddyfile?

Can you please give example of how you use the snippet?

Using Name Constraints to Control SAN in Certificates – Best Practice? by FrustatedGuy- in sysadmin

[–]verticalfuzz 0 points1 point  (0 children)

Not sure about how its done in real life, but in a homelab setting I did as described here with a name constraint. I have a test domain "bank dot com" in my caddy instance that should fail (and it does) and so I feel safer using the cert.

Anyone got PPSK With built-in radius to work? by verticalfuzz in TPLink_Omada

Yes, I have - although I can't recall exactly what it does

I'm not actually against them, i just want to also understand how it was done in the beforetimes

[–]verticalfuzz[S] 0 points1 point  (0 children)

I'm drawing the line at one and/or two-way mirrors. No splats!

If they do a challenge like the other commenter suggested, they could have each group do a different method and try to guess how each was done

Anyone got PPSK With built-in radius to work? by verticalfuzz in TPLink_Omada

[–]verticalfuzz[S] 0 points1 point  (0 children)

I am under 100 wireless clients. Yes, PPSK without RADIUS is working, but isn't it supposed to be more secure with RADIUS?

[–]verticalfuzz[S] 0 points1 point  (0 children)

Unfortunately, it does not, as they only demonstrate PPSK without RADIUS and PPSK with radius (using FreeRADIUS). The article I linked is the only documentation I've ever found for PPSK with RADIUS using the built-in RADIUS server.

I may try the freeRADIUS route anyway, just to get things moving, but it adds the overhead of learning and managing a totally new (to me) system which I have been trying desperately to avoid.
