Sysadmin

We're happy to announce the release of BusKill v0.7.0!

Most importantly, this release allows you to arm the BusKill GUI app such that it shuts-down your computer when the BusKill cable's connection to the computer is severed.

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

Watch the BusKill Explainer Video for more info youtube.com/v/qPwyoD_cQR4

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

Upgrading

You can upgrade your BusKill app to the latest version either by

1. Clicking "Update" in the app or
2. Downloading it from GitHub

Changes

This update includes many bug fixes and new features, including:

1. Adds support for 'soft-shutdown' trigger to GUI
2. Adds a new buskill.ini config file
3. Adds a new "Settings" screen in GUI
4. Merges kivy & buskill config files into one standardized location
5. Fixes in-app updates on MacOS
6. Fixes lockscreen trigger on Linux Mint Cinnamon
7. Fixes background blue/red disarm/arm color to propagate to all screens
8. Fixes --run-trigger to be executed inside usb_handler child process and communicate to root_child through the parent process

You can find our changelog here:

• https://docs.buskill.in/buskill-app/en/stable/changelog.html

Documentation Improvements

We've also made many improvements to our documentation

1. Updated the Software User Guide to include how to arm the BusKill app with the soft-shutdown trigger in the GUI
2. Added a manpage
3. Better documentation on how to build your own USB-C BusKill Cable
4. Better documentation on how to test the buskill app
5. Fixes in Release Workflow
6. Added some additional related projects to our documentation

Soft-Shutdown Trigger

This release now allows you to choose between either [a] locking your screen or [b] shutting down your computer when you arm the BusKill app from the GUI. By default, the BusKill app will trigger the lockscreen. To choose the 'soft-shutdown' trigger, open the navigation drawer, go to the Settings Screen, click Trigger, and change the selected trigger from lock-screen to soft-shutdown. For more information, see our Software GUI User Guide.

BusKill Now in Debian!

We're also happy to announce that, with the release of Debian 12, it's now possible to install BusKill in Debian with Apt!

sudo apt-get install buskill

Testers Needed!

We do our best to test the BusKill app on Linux, Windows, and MacOS. But unfortunately it's possible that our app doesn't fully function on all versions, distributions, and flavours of these three platforms.

We could really use your help testing the BusKill app, especially if you have access to a system that's not (yet) listed in our Supported Platforms.

And in this release, we specifically would like you to help us test the new soft shutdown feature. Please let us know if it does or does not work for you.

Please contact us if you'd like to help test the BusKill app :)

This is different from last week's warning: https://www.bleepingcomputer.com/news/security/300-000-plus-fortinet-firewalls-vulnerable-to-critical-fortios-rce-bug/

Fortinet is on fire :)

Does anyone want to see sysadmin blogs/guides posted here? I used to check sysadminblogs but the quality of content used to vary a lot. Would this be helpful or just clutter the feed?

I have seen the documentation saying to build an empty VM with slightly more space for each volume than was on the physical server, then use clonezilla to create an image of the server, then import it. That seems ok, but I'm hoping someone out there has more real-world experience in doing this and can share if they did it differently, or encountered any pitfalls.

As my environment matures, I am moving from "Hey I have 1 physical server with everything on it" to "Let's use a hypervisor and spin off services onto their own." When the base OS is P2V'd, I'll be able to have 2 hypervisors and start implementing HA. I've been using this system as a scratchpad and dev box for 10 years and would love to just migrate it over.

Hello c/sysadmin, and welcome to the Patch Megathread! I'm editing this post and leaving it up as a single catch-all sticky post for patch days for the time being, since we're not seeing enough activity to warrant new threads IMO. If someone wants to help moderate / curate content and actively create new patch day posts, please let me know and I'll add you to the mod team.

This is the place to talk about the latest patches, updates, and releases. We put this thread into place to help gather all the information about this month's updates: What is fixed, what broke, what got released and should have been caught in QA, etc. We do this both to keep clutter out of the community, and provide a singular resource to read.

While this thread is timed to coincide with Microsoft's Patch Tuesday, feel free to discuss any patches, updates, and releases, regardless of the company or product.

Remember the rules of safe patching:

• Deploy to a test/dev environment before prod.
• Deploy to a pilot/test group before the whole org.
• Have a plan to roll back if something doesn't work.
• Test, test, and test!

Will this community doing the monthly patch Tuesday thread that was on Reddit? Was sometimes pretty useful

Apparently they only sent 3 notification Emails, which a large number of their customers are reporting they never received. No one at InfluxData thought to do a scream test or even check the traffic levels to the region before deleting the data.

I have a customer with an old Windows Server 2012 with hyper v cluster configured for 2 nodes. One node died completely. I have 2 new HP proliant 360 Gen10 running Server 2022 DC and a big SAN, and I am trying to figure out the best way to move over the 6 VMs on the existing host. I’m new to this process but it seems like the host OSes must match for me to move the old VMs over. Is the best way to just export a Datto backup of the VMs to the new cluster? Any way to do this live? Any advice I’d appreciate and apologies if I wasn’t clear at all.

I have inherited some cloud hosted vms, with several services hosted in docker containers on these. Think we server and then DB, both hosted in separate containers. Several (overpriced) vms are involved. Would really like some pointers as to how I can get into these / edit them. Would really like to consolidate. I use proxmox at home and am comfortable in Linux but this is new to me. Any docs / tutorials would be super helpful. Still don't really understand why the design was done quite like this, so if you have insight on that, please let me know why you would do it this way. Thanks!

"Good" as in something that looks just as good as an RH cert on my CV. I was considering LFCS, but I haven't come across any job listings mention LFCS (at least, not where I live).

Incident started at 1645 UTC. No resolution yet.

We're installing a new app on a secure network. The vendor has requested we allow access to gstatic.com. That seems overly broad to me and unsafe. Thoughts?

Hello,

Does anyone have problem with VMware vSphere when interacting with Firefox browser? It's working but after TAB change or not focusing window the interface freezes.

This started when Firefox was updated to version 110 I believe. I tried on Windows and on Linux but behavior is the same. Deleting Cookies didn't help.

The interface is working well on Chrome, Edge..

vSphere version: 8.0.1

My organization just lost a entire email account full of emails needed for a law suite.

What happened was me or someone else (we don't know who) accidently deleted a gsuite account a few months ago. This account was from a employee who pasted away a few years back. We didn't realize that it was deleted until we needed it.

I like many people I had the misconception that data in the "cloud" can not be deleted. I was entirely wrong. We are now in some serious dodo and I don't know what we are going to do.

Getting really close to purchasing and I'm kinda on the fence between dmarcian, dmarcly, and easy dmarc. However, I'm open to pretty much anything with realistic pricing if you have alternatives to recommend.

I assume all 3 of these would get the job done, as they all seem to support dashboards, alerts, and forensic reporting. I'm curious about email volume limits though, I don't see as crystal clear picture of pricing when it comes to that - does anyone have first hand experience they'd be willing to share?

• single domain in Exchange Online
• email volume just crept up over 100k monthly in May/June

I was thinking of setting up a seedbox. Seeding will mean that the hard drive is being read from virtually non-stop. Is it fair to say that hard drives are designed for this? Or would this reduce the operational life-span of the hard drive?

For example, I was trying to find some spec in the Seagate Barracuda hard drive specifications document, but I wasn't able to find anything specific to this (or perhaps I just missed it).

I'm not exactly sure if this is the right community to post this, so let me know if there's a better place for it to go.

Hello everyone,

I'm wondering if we could have similar post/thread like on Reddit for Microsoft Windows monthly patches?

What are your ideas about that?

Have a nice day!

Working on a medium sized office network which only has a single PoE switch for WAPs. About 200 users. No copper to the desk... It made sense to buy a second PoE switch to give a bit of redundancy, even if it's for manually swapping cables in case switch A dies.

Plug in switch, wait for power up and decide to test the manual failover over lunch. Gateway plugged in, flashing lights. WAPs plugged in, flashing lights. Wireless network visible but can't connect as there's no DHCP. Swap everything back and we're back in business.

The switch is unuseable until I've installed an app, created an account, onboarded to a "cloud" and configured from my phone.

Oh HP, how you have fallen from the rock-solid days of procurves and have degenerated to the unfortunately named Aruba "Always On"

Rant over.

Time for a new beginning!!!

Greetings SysAdmins. I am looking for a way to automate monthly windows updates for some of my servers. Currently I do them manually during maintenance period. The somewhat unique part I have is that they have to be done in order.

server1: Update, Reboot, back on; then Server2: Update, Reboot, back on; then on and on for 10 servers.

I'm open to ideas, we have (shudder) WSUS but if you've experienced the ability to do updates in this scenario in other apps I will explore. Something ideally that can determine that the server has rebooted and move on to the next, or say server1 wait 25 minutes then server2 wait 25 minutes...

Thanks

Anyone else having issues?
