One of these services is a simple fileserver via NFS. I however ran into a problem when I tried to automatically mount NFS shares over Wireguard via fstab. In this post, I will show what my problem was and how I fixed it. Prerequisites I am assuming that you have a server and a client, which are connected via Wireguard. The client runs a Linux-distribution with systemd and automatically starts Wireguard at boot by use of the wg-quick@wg0. https://mrtijn.nl/blog/2020-07-30-virsh-console-access/ Thu, 30 Jul 2020 20:42:03 +0200 https://mrtijn.nl/blog/2020-07-30-virsh-console-access/ Sometimes it’s a hassle to open up virt-manager for just running a quick command on a guest VM. Luckily, virsh has the console command to attach to the serial console of a guest. But because the serial console is not by default enabled on Ubuntu Server (at least, not as far as I know), you have to enable it manually. For this, I created a small ttys0.service file: [Unit] Description=Serial Console Service [Service] ExecStart=/sbin/getty -L 115200 ttyS0 screen-256color Restart=always [Install] WantedBy=multi-user. https://mrtijn.nl/blog/2020-01-30-sftponly/ Thu, 30 Jan 2020 20:42:03 +0100 https://mrtijn.nl/blog/2020-01-30-sftponly/ I wanted to set up an easy and secure way to use the storage on my server as a personal “cloud storage”. I also wanted it to be isolated from everything else on the server. To do this, I used a chrooted sftp-only ssh user. There are probably other ways to do something similar, but I went for this option because I didn’t need to install additional packages. Prerequisites You only need a Linux server with ssh. https://mrtijn.nl/blog/2018-10-22-how-i-should-use-gpg/ Mon, 22 Oct 2018 12:00:00 +0100 https://mrtijn.nl/blog/2018-10-22-how-i-should-use-gpg/ GPG, and the OpenPGP protocol it implements, are both quite unforgiving. You can find plenty of best practices, usage tips and tutorials on how to use it, and you’ll find plenty of best practices that aren’t enforced by the program, bad defaults or outdated recommendations. I have no illusion that this one of many blog posts on GPG will change anything. I however hope that you’ll maybe learn a few things about GPG, which you can combine with abundantly available other sources. https://mrtijn.nl/blog/2018-09-19-watching-dvb-t-tv-with-vlc/ Wed, 19 Sep 2018 16:00:00 +0200 https://mrtijn.nl/blog/2018-09-19-watching-dvb-t-tv-with-vlc/ Watching DVB-T TV with VLC So a few days ago, I experienced the rare moment where I actually wanted to watch some TV. I however don’t own one, but I do have a computer and an RTL-SDR. I initially bought it to receive ADS-B data from airplanes, but it had recently just been laying around to collect dust. The device, which is based on the RTL2832U chip, is actually intended to be used as a DVB-T receiver.
