What are you working on? Feb 2021

Keep them quite well vented. Lithium batteries can become a too much hot ladies.

LiFePO4 is reported to be much safer than most other lithium chemistries. Power density suffers, naturally, but they’re quite safe–and have a much better cycle life than lead-acid.

I posted a few weeks back that the CA seems to work just fine for TLS certs, and that continues to be the case. I’ve shelved Gluu for the time being in favor of LemonLDAP::NG, which I’ve discussed more here:

I’m a little unclear on how to use the CA to issue both TLS and SSH certs, but once I get that piece figured out, I think I’ll have what I need to put them together.

Hi, How did you setup these inputs in Grafana ? Which Sensor device is sending the metrics ?

I’m using a somewhat-customized version of Grafana called Kotori:

Pretty much it’s “throw JSON at it”. That’s done by this software, which talks with both the inverter and the BMS:


Thanks, will look at this, specially Kotori for my own personal project

I’m tired about my scapegoat.
Therefore… yum install kmod-r8168, let’s see if my DG31PR stops being lazy…


  • IKEv2 tunnel starts jumping (cr4p)
  • Zyxel Firewalls seems to have some “snafus” on HTTPS (25 firewalls needed some new rule)
  • qLocker got my friend (“Do you have have a backup?” “Pick one: no; absolutely no; what is a backup?”)
  • new customer with old pc and dubious licenses
  • 4 hours of sleep

And worst of all

  • too hot to have a nice round of single malt

Happy saturday to everyone…

So that part took a little bit of doing, which I’ve documented here:

And the “SSO for SSH” with LemonLDAP::NG is working well, as described here:
