How to fix FreeBSD 11.2-RELEASE not booting because of Virtual Box driver.


I entcountered a bug with virtualbox-ose-nox11-5.2.14_1 & virtualbox-ose-kmod after upgrading to FreeBSD 11.2-RELEASE on first reboot.


The system would enter a boot loop with this crash error:




supdrvGipCreate: failed to allocate the GIP page

                The best way to identify if a device is vulnerable or actively being leveraged for UPnProxying is to scan the endpoint and audit your NAT table entries.

Helpful SSH tips


Executing a single command:


ssh USER@HOST ls



sudo requires interactive shell, it can be enabled with -t parameter:

Help Desktop Applications usegpg-agent for Yubikey.


How do I use my Yubikey with desktop applications like Sequel Pro or MySQL Workbench?




When you use the GPG Agent (with or without smartcard, the agent takes care of that, so it's not a problem if you don't have one I think) it should ask for the passphrase of your GPG key (or the PIN of the smartcard in my case) and not the SSH password.


But how it works now is that the SSH attempt asks for the SSH password, not the GPG passphrase.


Ok, here is an example:
