Can't say I noticed, but thanks for the feedback

I ended up using a cheap health band that isn't paired with anything As soon as it gets paired its no longer discoverable On the plus side, the battery life on this is great

Good to know the video was useful

I didn't notice one myself or add one And It's been powered off several times since and still working fine

Looks like it is for the RTC, real time clock which this board seem to have. I have installed it now. It is under the Oled-display.

Good to know the video was useful and thanks for the sub

Not something I've really looked into but you could create your own template So you start with a cloud-init image, and create a VM from that You then configure that as your golden template and use that to create other VMs Creating your own cloud-init image though looks to be more complicated

When you use keys, both servers need to agree to use the same one and it's good to use different ones for different purposes So you'll probably want one for DNS to DNS And another for DNS to DHCP

Thank you very much

I am finding the combination of Prometheus and Grafana very useful So good to know this video helped

Thanks for supporting the channel

Thanks for the feedback Good to know the video was helpful

Thanks for the feedback This has been a very useful KVM At some point I need to expand it though so it can support more computers

It is a big upgrade, so good to know the video helped

Thanks for the feedback and good to know the video was helpful As for the drives, I've found Proxmox VE lets you change the format during a migration of the drive And it's better to use qcow2 than raw because then you can snapshot the VM, but you can only use raw when a physical drive is using LVM formatting If a drive is raw now, you can change that when you migrate it to a ZFS storage for instance, you'll probably find it will even chose qcow2 by default To migrate a drive, go into the hardware section of the VM, select the drive and in the top menu is a drop down menu called Disk Action Click on that and select Move Storage Then select the target storage and format choice I always tick the option at the bottom to delete the source drive whenever I migrate a drive, because otherwise it just wastes disk space Basically it copies the original file to the new target so that option is just an extra step to remove the original source file

Wow, that many times

Thank you very much

Proxmox VE is taking advantage of the underlying Debian OS which does the virtualisation and networking So traffic hits the physical switch, and with a Linux bridge attached to it, the bridge then decides what to then do with that traffic

Usually when traffic doesn't get to where it needs to be, it would be a VLAN tagging issue If you're familiar with tcpdump, you can install and run that on Proxmox to see what the DHCP traffic is up to But if Windows is more your thing then configure the switch to mirror traffic from the pfsense and Proxmox ports to another switch port Plug a Windows computer into that port and you can monitor the traffic exchange using Wireshark If you don't see DHCP requests being sent out from Proxmox, then you need to check that port and the VMs for tagging Or if you don't see any replies from pfsense then you need to check that port and the VLAN tagging on pfsense

It still works for me on 8.2 You probably have a caching issue on your web browser So after you've restarted the service, you'll want to clear out any cache on the web browser I find logging out of PVE in the web browser, using Ctrl-F5 to clear the cache, then closing the browser helps Next time I open the browser and connect to PVE, the notification is then gone

@@TechTutorialsDavidMcKone Thank you for answer! I'll try again.

The management interface is easy enough to change as you just add an interface and login to that going forward I did a video for NFS storage as an example, which involves a dedicated interface, so again you just add an interface but you might have to drop the existing storage connection then create a new one that is pointing to the new IP address. It shouldn't be impacting as long as you aren't running VMs on nodes which use that storage, because the change is global By default, the first interface you create is used for migrations, and I did a video to change that. As long as there's no migrations going on it shouldn't be impacting The bigger problem is the interface used for clustering Going by the notes: "Changing the hostname and IP is not possible after cluster creation" pve.proxmox.com/wiki/Cluster_Manager Although you can't change the IP, you should probably be able to go into the CLI and change the subnetting You do have to factor in updating firewall rules for all this, if you're using the PVE firewall solution that is I haven't done anything covering Ceph as it requires too much extra hardware 3 servers is the minimum, but the recommendation is 4 or more and it needs dedicated 10G NICs and one or more switches with enough ports. You could wire the servers in a loop instead but then each server would need 2x10G NICs just for Ceph, plus the additional NICs for everything else In addition, it needs higher grade Enterprise SSDs for instance so I'm not currently planning on putting out videos on Ceph

There are at least two user accounts involved here 1) You need to be able to login to Semaphore so that you can configure it and ultimately run Ansible playbooks, etc as scheduled tasks. You create at least one account for it during its setup. But that account is specific to Semaphore 2) Ansible needs access to others IT devices to make changes to them etc. and all those devices have to have a user account for that user so that Ansible can login to them I'm using SSH key authentication, so at this point in the video I'm pointing Semaphore to the private key for my Ansible user In other words, the Sempahore user account is used to manage Semaphore, but you have a separate Ansible account that is used to manage devices

The documentation can be a bit overwhelming I think But I've been using ISC's products for a long time now, and I do prefer them

The folder location is up to you But, I have a dedicated user account for Docker, so I run everything from that user's home folder to make sure that user has access to files I also use Docker Compose and so the YAML file for that goes into the home folder Within that home folder, each container has it's own sub folders to store configuration files in

@@TechTutorialsDavidMcKone Thanks for the reply, I've only messed about with Docker a little and having a dedicated account seems like a good idea as i had issues with permissions previously and that would help.

That's good to know, thanks for the feedback

I'll have to catch up with where the devs are at with Stork Although at first glance, there's still not an official release and so it wouldn't be suitable for production

Any video will depend on experience If you have no idea what NTP is for instance, then NTS would be more difficult to understand

@@TechTutorialsDavidMcKone I found the video useful and appreciate your effort.

It sounds like the Ansible user account requires a password and that needs to be supplied to gain sudo rights Add this parameter at the end when you run the playbook so you'll be prompted for the sudo password -K The alternative is to add this --ask-become-pass

Unfortunately I no longer use XCP-ng as although I managed to get USB passthrough working through the CLI it led to too many problems for me There was a Windows client that could do USB passthrough through the GUI It stopped being supported a long time ago but it looks like a new BETA version is being released by the community github.com/xcp-ng/xenadmin/releases/ Other than that, there is an official management suite but it will cost money

Normally computers don't allow multiple interfaces in the same subnet but that error suggests you might It's unusual to assign IP addresses belonging to a /16 network as it's too large. Typically it would be broken down into /24 subnets for instance I'm wondering if a server has a NIC with an IP address and /16 mask in error. If so that would overlap with a lot of other subnets and lead to confusion I suggest you check to make sure all of the servers in the cluster have a network interface in the same subnet and that these are unique before you try to assign a migration network You won't want a mix or overlap of subnets, for instance, one server with an IP of 10.1.1.127/24 and another with an IP of 10.1.1.130/25 for instance From the first server's perspective, the second server is in the same subnet, but the second server will try and connect using it's default gateway as the subnets are different And what you'll want are all servers with a network address in the same subnet

@@TechTutorialsDavidMcKone Hallo David, you are right - i found my mistake - two devices in one subnet... - Because of any errors i have to change my firewall. On the occassion i installed the proxmox cluster new and changed from 192.168.x.x addresses and /24 subnets to 10.x.x.x addresses and /16 subnets and VLAN's for clearer organisation. I used different addresses in the same subnet for different lan ports. An ceph installation error message i understood... ;) As you suggest i changed for this device back to /24 subnets and now it works. I'm not sure but it seems that vlan's not everywhere work and i'm searching for a way to implement trunk interface in SDN... Thank you very much. Sincerely Micha

Thanks for the feedback and good to know the video was helpful

I absolutely agree. David does a fantastic job. His work is a benchmark for others to work towards.

Good to know the video was helpful I think that's the first time I had to do that, but SHA1 was used for a long time

It depends Nginx and Apache are popular web server solutions But static websites can be good if you don't need fancy dynamic content They have big advantages of being more secure and quicker to serve content My own blog for instance is just static content built using Hugo www.techtutorials.tv

Good to know I do like Semaphore as I think it makes it easier to automate the maintenance jobs

It's just the wall behind my computers at home After a while the walls or even entire rooms end up with themes After buying a print of Audrey Hepburn, this side of the room became Hollywood actresses

Templates are very useful but now I'm steering towards automating as much as possible; less to backup, quicker to recover, quicker to modify, etc Another benefit of automation though is it's easier to scale because you just deploy the same change And as long as you test a change in a lab, you should get the same result in production

Early on, some firewalls didn't even have an implicit block rule Then we got some firewalls that log implicit rules and some that don't Then we got a global setting to enable/disable that logging So at some point it just became a common practice to create your own rule at the end as at least you can be sure

It's hard to believe this used to be a hidden feature and you needed to know the key combination to access it It's so useful

@@TechTutorialsDavidMcKone Yeah. On the version i used on Linux it was hidden as well :(

Yeah, but I was really curious what was on the network trying to contact something in that country You need a baseline to know what your devices are up to, what external computers they connect to, including the country, company details, etc. Turns out the IP address is actually allocated to an ISP here in the UK But for some reason Zenarmor thought it was allocated to someone in Australia

Now that says something I've got used to the annoying update reminder, but didn't notice the font

I've never ran into that issue myself, but good to know Thanks for sharing

Thanks for the feedback I think Node-RED makes it so much easier to set up automation rules and troubleshoot them I don't know of another smart home solution that incorporates anything like this, which gives HA such an edge So, good to know the video was helpful

It's from a root CA using openSSL I have a video for that if you're interested ua-cam.com/video/nOSl4dmywe8/v-deo.html But now I'm leaning towards Step-CA as it basically automates the certificate process, a bit like Let's Encrypt, but it's an internal server ua-cam.com/video/fhqnj4J7gpU/v-deo.html
