Now we can use OpenVPN and the Yubikey + YubiCloud OTP service to do authentication for VPN connections.
Thanks to the OpenVPN team for fixing issues preventing this prior to v2.4.3.

New guide up - right here.
My Xen servers main board didn’t have a second PWM controlled fan header to use with a PWM fan hub for the 3 case fans. Its a 4RU case - which has server grade 140mm fans that can draw up to 0.9A each and get up to around 3600 RPM.
So here’s how I used an ATTiny85 to generate a PWM signal from the variable ‘Speed Control’ voltage on pin 2 of the SYS_FAN header.
With the release of kernel-xen version 4.9.40, I have enabled CONFIG_TCP_CONG_BBR. This adds support for using BBR to improve the throughput from your servers (mostly web servers) to your clients.
If you run my kernel-xen package on your Xen guests, you can also take advantage of this new feature.
To enable, ensure you are running kernel-xen version 4.9.40 or above, then create a file called /etc/sysctl.d/enable-bbr.conf containing:
1
2
net.core.default_qdisc=fq
net.ipv4.tcp_congestion_control=bbr
You can activate this by typing: $ sysctl -p
The changes will automatically apply at the next system boot.
To read more about BBR and why it makes such a difference, head on over to acmqueue for a far more in-depth analysis than I could provide.
