I recently wanted to update my old Zigbee- and Z-Wave USB adapters that I’ve been using with my Home Assistant setup for some years. I’ve taken a look at the products available, and chosen my replacement products. I’ll attempt to list my reasonings for choosing these products below.

I recently had to get GPU transcoding in Plex to work. The setup involved running Plex inside a Docker container, inside of an LXC container, running on top of Proxmox. I found some general guidelines online, but none that covered all aspects (especially dual layer of containerization/virtualization). I ran into a few challenges to get this working properly, so I’ll attempt to give a complete guide here.
34 CommentsUsually I don’t bother installing appropriate (i.e. public/proper) HTTPS/SSL-certificates for management softwares and other “internal” software. However, making parts of Cisco Prime Infrastructure available for “outsiders” can be quite useful, hence I saw the need to install a proper certificate.
I recently had to do this while installing Cisco Prime Infrastructure 3.0, so I thought I’d document it, since it’s not as straight-forward as one would think. The last time I did the procedure, was after installing Prime Infrastructure 2.0 almost 2 years ago.
There are basically three steps;
1) Fetch CA + properly convert the certificate
2) Install the CA certificates
3) Install the actual certificate

Recently I came across an issue with Windows DHCP & DNS, specifically related to Cisco AP’s and DDNS. By default Cisco AP’s have period in the hostname (APxxxx.yyyy.zzzz), and this apparently causes issues for Windows DHCP/DNS regarding DDNS. If you have a scope with option 15 (Domain Name) set to foo.bar, and you have clients that only returns option 12 (hostname) and no FQDN (option 81) you’d expect Windows to append option 15 to the hostname. In the case for Cisco AP’s, they seem to only return option 12. You’d then expect Windows DHCP to use APxxxx.yyyy.zzzz.foo.bar as the FQDN for the DDNS update, but this is not the case. In stead, it tries to update the DNS with APxxxx.yyyy.zzzz as the FQDN (where yyyy.zzzz is considered a domain due to the period), hence it will obviously fail, as you don’t have any zone yyyy.zzzz configured in your DNS.
When trying to convert an 1142 AP from LAP to Autonomous AP, I did a mistake. I copied the new IOS (.tar) with the ‘copy’-command. However, I should’ve used the ‘archive /xtract’-command. When I reloaded, the AP presented me with this;

4 CommentsSince I recently configured and installed a MySQL-cluster, I thought I’d share the procedure. A lot of the examples around explains how to set it all up on the same machine for “testing purposes” — which, in theory, is the same as setting it up on different machines. I’ll be explaining the latter, that is, installing it onto different machines.

Leave a CommentEver had the need to use PVLANs in conjunction with one or more trunks, but your Cisco-switch doesn’t support it? I did. And I found a solution. It works well, but if you need to trunk many PVLANs, then this is not the solution you’re looking for; get a 4500/6500 to play with instead.
I’ll be using my scenario as an example in this article, but you could use it for whatever other reasons you might have. At school we have a Cisco-lab, with 5 racks containing various Cisco-equipment. For a while now, there’s been situations where you’d really like a DHCP-server, TFTP-server, or similar, at hand. So, since we already had a VMware ESXi-server running in the lab, it was fairly easy to setup a dedicated lab-server. However, since this ESXi also had to be publicly available, and the lab-network shouldn’t be, we decided to use a trunk between the ESXi and our 3560G (sitting as a gateway between the lab, the servers, and the internet). Each VM is then assigned to their respective VLANs. All well so far.
