I'm having trouble using MeshCommander to connect to the AMT in my HP Z4 Workstation because I don't know the IP address, and MeshCommander isn't finding anything. According to the HP Bios Simulator document, I can find the MAC Address of the AMT network adapter similar to the one presented on Page 7. I checked the BIOS of my HP Z4 G4 workstation and noted the MAC Address. Since the same machine has a Linux OS installed, I checked the network interfaces and found the one with the same MAC Address.

eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 XXXX::XXXX:XXXX:XXXX:XXXX  prefixlen 64  scopeid 0x20<link>
        ether [SAME_MAC_ADDRESS_AS_SHOWN_IN_THE_BIOS]  txqueuelen 1000  (Ethernet)
        RX packets 415  bytes 52182 (50.9 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 14  bytes 1172 (1.1 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 16  memory 0x94500000-94520000

The issue is that the AMT network adapter does not seem to be getting an IP address. Here are the steps I've taken:

1. Used the command show arp | grep 84 in the EdgeRouter-X shell, but it didn't return any results. (The MAC address starts with "84")
2. Checked the rear port of the machine, and the LED lights are blinking.
3. The switch also shows blinking lights.

The device does not show up in the router DHCP lease, and I'm unable to see it in the ARP table.

How can I troubleshoot to obtain the IP address for the AMT network adapter or figure out why it isn't getting one?

I'm attempting to install TrueNAS Scale (24.04.0) in Proxmox (8.2.2), but the installation fails with the error message lsblk: CANT_FIND_vda3_OR_vdap3: not a block device.

Below is the table of the Proxmox VM configuration:

• During the installation, the option "Allow EFI Boot?" was answered with "NO."

What could be the issue in the VM disk configuration causing TrueNAS installation to fail on the virtio0 disk?

So I am using ZeroTier VPN to access local devices, routers(to which I installed ZT on the router, explained here), local servers and devices remotely. However, accessing my router for example I only access it without HTTP, e.g. http://192.168.1.1 which is basically the same way I do when I am physically near the router itself.

On my laptop, there's the ZeroTier Virtual network adapter which is the one handling my access to the IP mentioned so even I am away from the physical location, I can access the router as if I am there, hence, VPN.

My question is, accessing non-HTTPS over VPN is it safe to access non-HTTPS devices? Usually passwords / sessions are part of HTTP payload either through HTTP query parameters or headers.

Here's a diagram of the Network Setup I am trying to accomplish:

So we have offices with LAN-connected devices that we need to access remotely.

Initial solution is to try using ZeroTier(ZT) installed in a Ubiquiti EdgeRouter X (UBNT) device.

So I managed to install ZT with the UBNT via its Linux-based EdgeOS and SSH:

ubnt@ubnt# sudo -i
root@ubnt:~# curl -s https://install.zerotier.com | sudo bash

And got to access the Edge OS (Edge Max) interface through the ZeroTier Global IP, so I can access my router anywhere/remotely.

However, how can I "remotely" access the LAN devices connected to the router? For example, I have one device connected to eth1 with Local IP in the router, 192.168.1.39

How can I access this using the ZeroTier network?

Here are the interfaces in my EdgeRouter X:

ubnt@ubnt:~$ show interfaces
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface  IP Address            S/L Description
---------  ----------            --- -----------
eth0     192.168.0.157/24         u/u Internet
eth1     -                 u/u Local
eth2     -                 u/D Local
eth3     -                 u/D Local
eth4     -                 u/D Local
lo      127.0.0.1/8            u/u
       ::1/128
switch0   192.168.1.1/24          u/u Local
ztzlgezugz  10.148.18.15/24          u/D
       fcf0:4d28:e363:18fd:910f::1/40

What could be missing in my software and hardware setup to allow the LAN devices to be accessed over the internet?

UPDATE:

I also want to emphasize that the Local Instrument/Devices mentioned in the diagram are devices that we cannot install any software into it, neither how the it's network operates. Example are Printers, Scanners, Imaging Devices, NComputing Terminals, etc. We can only access it via LAN.

So I managed to install ZeroTier with the Ubiquiti Edge Router X via:

admin@edgerouter# sudo -i
root@edgerouter:~# curl -s https://install.zerotier.com | sudo bash

And got to access the Edge OS (Edge Max) interface through the ZeroTier Global IP, so I can access my router anywhere in the world which is great.

However, how can I access the LAN devices connected to the router? For example, I have one device with Local IP in the router, 192.168.1.39

How can I access this using the ZeroTier network?

How can you use Amazon S3 or S3-compatible Storage as NFS? Is there a way to achieve this?

Something that can be accessed through an external network (internet, public) using NFS protocol.

I have managed to be able to passthrough a PCIe GPU (AMD RX580) into a Windows 10 Guest on a Windows Server 2016 Standard host.

The problem is that whenever the GPU will be used this error throws up:

The driver was installed through Windows update

The PCIe passthrough was done using Powershell (Administrator):

1. Set-VM -Name "Parsec" -AutomaticStopAction TurnOff
2. Dismount-VmHostAssignableDevice -LocationPath "PCIROOT(0)#PCI(0301)#PCI(0000)" -force
3. Add-VMAssignableDevice -LocationPath "PCIROOT(0)#PCI(0301)#PCI(0000)" -VMName "Parsec"
4. Set-VM "Parsec" -GuestControlledCacheTypes $True -LowMemoryMappedIoSpace 2000MB -HighMemoryMappedIoSpace 8000MB

What could be missing here?

I recently found about this video link showing that ESXi is able to passthrough PCIe onto a Guest VM:

https://www.youtube.com/watch?v=mhZzAjlNdWc

The question is, what is the difference of GPU passthrough vs PCIe passthrough does it mean PCIe passthrough can only be used on one Guest VM and GPU passthrough means multiple Guest VM can share a single GPU?

I have installed Xenserver 6.2 in my machine with ASUS A58M-E motherboard and AMD A8-6600K APU (CPU). Now even if the IOMMU is enabled in the BIOS, Xenserver is reporting that IOMMU is not enabled and thus Virtual Machines cannot take advantage of the Radeon HD of the APU.

What is the correct way to make IOMMU with Xenserver and to allow GPU assignments for Virtual machines running in the Xenserver machine.

In my DNS manager, GoDaddy I made some A Record that points to *.mirror for my domain

Now when I access URL 123.mirror.mydomain.com from the browser I can see that my app is loaded, and its all OK.

My problem now is when doing a CNAME point to the URL above on another domain DNS manager like this:

Accessing 123.otherdomain.com which I expect to "forward to" 123.mirror.mydomain.com I only get this 404 error:

What I am missing here?

I added a CNAME record in GoDaddy

**.mirror -> ghs.googlehosted.com

My goal is to be able to point to a web app using username.mirror.xyz.com

However this works partially, the only thing that works is

test.mirror.xyz.com

Other than "test" nothing works, I do not understand why is this happening?

I'm trying to do a WOL for my Xenserver in my lab environment. However I am not able to do it. I have enable the BIOS settings of the physical server, and from what I can see, even when the server is turned off, the LAN led lights is on.

Also I have enabled port forwarding in the router like this setting:

Name: Wake-on-Lan IP address: 192.168.0.255 Port: 9 Protocol: UDP

And I tried to do arp add 192.168.0.111 001E90E36581 255.255.255.0 9 and did a ping to that IP but I'm not getting any response.

How to "easily" forward incoming port 80to outgoing to port: 8080 for Windows Server 2003? The idea is that all traffice/incoming and outgoing from/to port 80 will be redirected to 8080.

I have a Windows server 2003 with two NIC one is setup to connect to the network with static IP/internet, and the other one is supposed to be used internally as DHCP server. However I am having trouble setting this DHCP. The taskbar icon shows the first NIC with static IP as ok, however the second NIC have limited functionality. I need this NIC to act as DHCP after following some DHCP server how-to.

Any ideas.

Is there a bandwidth efficient way to setup VM (like setting up Linux / Windows from Console) from a remote XenServer?

I am trying to setup Linux/Windows vm from a remote server; however the console is painfully slow. Is there a better way to do this?

Cheers.

what is the best Mail server to be used side by side with Apache tomcat (which host my main webapp) which I configured to run on port 80? Currently, I have this requirement that I need to setup a mail server under the same server with this address mail.mydomain.com
