Updating the cert on a Synapse Matrix standalone server

As usual, logging this so I don’t lose track of it later: https://www.linode.com/community/questions/18963/certbot-error-problem-binding-to-port-80 And the original content in case it goes missing: This is a common CertBot error when using the Standalone plugin (–standalone flag) during the certificate renewal/creation process. In this case, CertBot will attempt to use port 80 to create a temporary web server. You have […]

MFA in Office 365, not talkin’ bout Azure

Microsoft is frustratingly vague about support for basic MFA in all Office 365 offerings. They have these lists of feature support across different packages, which go into great detail and yet don’t include basic MFA. Maybe this post will get up in the rankings so others don’t have to spin their wheels looking for an […]

OpenVAS on the Raspberry Pi 4 works really well!

I’ve been trying to set up OpenVAS on a tiny PC like the RPi lately. Based on this post: https://dayne.broderson.org/2018/05/24/RPi_Vulnerability_Scanner.html I wasn’t expecting much success. And that’s what I found. It wasn’t really usable. I saw the TinkerBoard and the extra performance and RPi compatibility and thought that might be a good thing to try. […]

OpenVAS for simple vulnerability scanning

I’ve been looking for a simple security vulnerability scanning tool for a while now. OpenVAS looked promising in the past, but I always had trouble getting it to work. I decided to work through it this weekend and figure out what I was doing wrong. In a nutshell, here it is: GSM Community Edition and […]

Ubiquiti USG site to site VPN with a single controller

Quick note about how to make this work. If you want to have two Unifi Security Gateways connect to a single controller at one location, you need to open up a couple of ports. Specifically, 8080 and 8443 need to be open to the controller. I strongly suggest you make sure you have a fixed […]

More vSphere and VT-d, some success but not for long

I made another attempt at using VT-d for my cameras by going with Zoneminder under Linux. This actually worked and seemed to work ok but I really dislike Zoneminder! I tried Motion and kMotion instead and the good news is it works…for longer. I’m still having problems with kernel crashes after a day or two. […]

vSphere and VT-d not so rosy

Actually, it works but with limitations. No shock there. It turns out the PV-149 CCTV capture card I’m trying to pass through presents each channel as a separate Video and Audio device. What that means is I end up with 8 PCI devices that need to be extended. I’m running into a problem that might […]

Cisco ASA Standby device “copy TFTP” syntax

That’s a mouthful. I’ve been having a hard time figuring out how to successfully transfer images to the Standby ASA’s flash from the Active’s CLI. Finally figured it out. Here’s the syntax: failover exec standby copy /noconfirm tftp://{ip address}/{file name} disk0:/{file name} Without the /noconfirm it’ll fail. You also need a standby ip address on […]

Anyconnect for iPhone???

It’s now a month or so after the release of iOS4 and the Cisco Anyconnect Secure Mobile Client for iPhone is nowhere to be found. What’s up Cisco??? I want my Anyconnect! And anyone believes they’ll actually ship the Cius? HA!
