Intro Today, I received a free Technicolor TG799vac Xtream router from my ISP, which seems to have quite decent hardware according to my google-fu. I already have a router (two technically speaking), so I have no real need for it. But I have a way it might come to use. See, currently I have one router without any radio, which I use as my main gateway and router. This is a really nice machine for the most part, so I really like having it for that purpose. But since I also need WiFi at home, I have my old router which only runs as an access point, forwarding all traffic to my router. Since this AP is upstairs, it wouldn’t be too bad having another AP downstairs, maybe somewhere where it gives better WiFi to my garden or garage. This is the idea at least. ...

I have a really nice router which i use to run PFsense on, which has a lot of useful services. However, it does not have Wi-Fi. So in order to provide Wi-Fi, I have to use another device as an access point. In my case I don’t have a pure access point, but I do have another router. This guide can also be used to attach several access point to a single LAN, if you need more than one to cover your whole house. ...

I have docker container which wants access to a drive on its host, which in turn is mounted with cifs from a server on the local network. If you mount it normally with a -v host:container and try to access it from the container, you get an access denied. If you try the old classic SE-Linux-friendly -v host:container:Z, it will look like this from the container: root@c3ada26b1d90:/# l /data/* /data/backup: ls: cannot access '/data/backup/config.json': Permission denied 27177a66e938a02ae784c0bc9ccd74751a32c00f4fcaee22ef1d78894c70553a-stdin| config.json init-stdin| 27177a66e938a02ae784c0bc9ccd74751a32c00f4fcaee22ef1d78894c70553a-stdout| init-stderr| init-stdout| To make it work, you have to change the SE-Linux-type from cifs_t to something more container-y. In your /etc/fstab, you can mount it like this: ...

These are my installation notes for creating a lightweight linux desktop environment from scratch, which contains only the most necessary applications. I’ll probably update it slightly in the future, when I realize I have missed some application. It will contain both openbox and dwm, as I’m always torn between using a tiling versus a floating window manager. Mostly I prefer tiling ones, but with some applications, they simply don’t work well. ...
