I’m surprisingly level-headed for being a walking knot of anxiety.

Ask me anything.

Special skills include: Knowing all the “na na na nah nah nah na” parts of the Three’s Company theme.

I also develop Tesseract UI for Lemmy/Sublinks

  • Is there a way I can get Let’s Encrypt to dole out a wildcard certificate

    Yep. Just specify the domains yourdomain.com and *.yourdomain.com in the certbot request. Wildcard domains require the DNS-based challenge, but you’ve said you’re already good there. You don’t technically need the apex domain (yourdomain.com) but I always add it since I do have services running there.

    Any subdomains under the wildcard can use internal DNS or internal IPs on the public DNS (I do the former, but the latter works too).

    I used to run an internal CA, and it wasn’t too hard to setup a CA and distribute my root cert. Except on mobile devices. On Android it was easy, but there was a persistent warning that my network traffic could be intercepted (which is true when there’s a custom root cert installed), but it since it was my cert, it got annoying seeing that all the time. Not sure if Apple devices can even do that, but regardless, it wasn’t practical for friends who wanted to use my self-hosted services to install a custom cert when they were over.







  • Depends on what I’m transferring and to/from where:

    • scp is my go-to since I’m a Linux household and have SSH keys setup and LDAP SSO as a fallback
    • sshfs if I’m too lazy to connect via SMB/NFS (or I don’t feel like installing the tools for them) or I’m traversing a WAN
    • rsync for bulk transfer and backups
    • Snapdrop/Pairdrop for one-off file/text shares between devices with GUIs (mostly phone <–> PC)
    • SMB if I’m on a client PC and need to work with the files directly from the fileserver
    • NFS between servers
    • To get bulk data to my phone (e.g. updating my music library), I connect via USB in MTP mode and copy from the server via SMB or sshfs.




  • I’ve always thought the firewall color codes were arbitrary, though I might just have not paid attention all these years lol.

    Just to clarify: I meant connect your OpenWRT device to your hotspot instead of the AP you’ve been working with. Just to rule out multiple MACs being blocked on the AP.

    Beyond that, I’m not really able to help troubleshoot further, but worst case and if all you need is internet, you can set your OpenWRT device up so that it just NATs your downstream connections. Double-NAT, in most cases, is fine.
