Did I do it good or bad verifying the ISO with > checksum utility? Verifying the SHA256 hash is good. You can be pretty confident the ISO hasn't been tampered with, but the only way to be sure is to verify signatures per https://www.qubes-os.org/security/verifying-signatures/#how-to-verify-qubes-iso-signatures. If you can't figure out how to do that with gpg4win, you might want to get some practice with a GNU/Linux distribution instead. You can live boot Mint for example, and I think Debian 10 too https://www.debian.org/CD/live/#choose_live. Then you can use native gpg to verify the ISO. You could also install Virtualbox in Windows and run Debian or whatever in a VM to get familiar with it first. > Why do I have to verify Qubes Repos if I had verify the iso?

Re: [qubes-users] Wifi Antenna Boosters
Thanks a lot! That seams way better. So one just attach it and I works straight away? With no need to alter Qubes or install any software? And from and security point of view? Will it add any additional risk when connection to a public network using Tor? And any ideer how long the is reach? I guess the answer is in this numbers 300 Mbps, 125 Nand flash. The antenna I considered earlier could add 200 meters the the original retch of the wifi. I presume this one a lot more powerfull.

The ethernet link is down in sys-net. I tried using ip and ifconfig and ifup commands to bring it up, but it is still down.

[qubes-users] Re: Unsure about network device attachment to VMs
> Can someone help with this problem, right now just for getting my Qubes > installation started, keeping ethernet and other USB devices separate, and > with VPN installed somewhere. Detailed documentation can come later. Right now, I have the wireless device connected to sys-net, but I am trying to get ethernet through sys-usb. On installation, the list of services in sys-usb included network-manager, which was causing ethernet based networking to be connected directly in sys-usb and that was being used in sys-net (as far as I can understand). Now I have removed network-manager service from sys-usb and put it in sys-net. I then manually attach the LAN device to sys-net. However, this doesn’t seem to allow me to connect to network through ethernet. Running lsusb doesn’t show the LAN device in sys-net even after attaching. I am missing something basic here, it seems. When I try to create an ethernet connection in sys-net, there is no ethernet device to be connected to.

[qubes-users] Unsure about network device attachment to VMs
I am reinstalling Qubes, but I am not sure how to which devices to attach to sys-usb and which to sys-net. Earlier the network devices were directly attached to sys-usb and sys-usb was providing the network. This is the setting my new install started with. I am trying to avoid getting network directly from sys-usb. There seems to be some trivial thing that I am missing. For context, my laptop (Dell XPS 13 9370) has two thunderbolt USB-C ports and one normal USB-C port. It is the third port which is practically the only port I can use as things are setup, since it seems to be unadvisable to attach thunderbolt devices to Qubes. So I mostly use a USB-C hub, which has the ethernet port as well other ports. The laptop is not in the HCL list, but it seems to work fine with some issues. The documentation for Qubes is pretty good, but one problem is that it is better for those who either have no technical knowledge or have deep technical knowledge of how Linux and OS work, along with networking. I fall somewhere in the middle, so both kinds of advised are not very useful. I think, given that the online threats come from network, there should be a more detailed, technically middle-grounded documentation for setting up network on Qubes, including where should VPN go (various options and their pros and cons). Can someone help with this problem, right now just for getting my Qubes installation started, keeping ethernet and other USB devices separate, and with VPN installed somewhere. Detailed documentation can come later. Regards, Anil -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Doubts
It is because I need help. So, I am worried about privacy in the world of electronic communications. I heard about the existence of the NSA mass surveillance software, and from other countries ([prism-break.org](http://prism-break.org/)). I also usually read privacy policy and terms and conditions of what I am using. --- A little of my history, it is not necessary to read --- So I decide to use protonmail and tutanota for email services I decide to navegate in invite mode on google chrome. To install other mobile application in my phone that organize my email other than gmail. I discover thunderbird. I discover criptext. (https://criptext.com/) Run a vpn (reading terms and conditions & privacy policy: because there are someone that keeps logs and do not accept bitcoin) I used to think my communications where private doing this changes, until I started to realize that It was not. I discover a few articles saying that protonmail was not enough private. (https://eprint.iacr.org/2018/1121.pdf) This page says tutanota is not secure. (https://prxbx.com/email/) I read privacy policy of thunderbird saying they transfer clients data to the US. (https://www.mozilla.org/en-US/privacy/thunderbird/) I read criptext privacy policy and there is a lot of transfer data about each client outside the country Panama. I contacted with two organizations of mobile phone apps: mailbird and mymail asking why they have the same privacy policy and a few questions of their privacy policy I discover this article against windows, my OS. (https://www.gnu.org/proprietary/malware-microsoft.en.html) --- So I decide to install qubes os, to improve my security (I also read Edward Snowden recommendation and Edward Snowden case). First I saw three videos of people talking about qubes and their characteristics, one in livestream and two in youtube. Then I decide to follow step by step your instructions, but I have a lot of problems. I read that the website is hosted on github, but I discover in readme file that there is another website with other instructions. I decide to verify the ISO (4.0.1) that I download of your canonical webiste [qubes-os.org](http://qubes-os.org/), so I have a windows program called md5 & sha Checksum utility and it says it all right (open digest and confirm that iso sha256 is the same as in the hash sha 256 of website (https://mirrors.edge.kernel.org/qubes/iso/Qubes-R4.0.1-x86_64.iso.DIGESTS)). I decide also to try to do it with gpg4win program, but I do not know how to do it because is an iso, I do it with exe. I also try with the instructions of your website, but I do not know how to follow. How will be the process? Did I do it good or bad verifying the ISO with checksum utility? Another question: what do you recomment to clone github and then run a localhost server? I only know a program that you install with npm commands that is called: litte server. I read readmd from github, and with docker you can not do it because you have to have windows enterprise or pro (I only have windows home). If I have an ISO, and I have check with sha256, why do I want to verify with signatures of the others repositores? Where do I have to write all that commands? Do you need that someone host the website with url [qubes-os.org](http://qubes-os.org/)? It is because I do not understand one thing: I verify a software that could be manipulated by third parties, but the signature key too; isn´t it? So It makes sense verify the software when downloading only of third website, isn't it? Why do I have to verify Qubes Repos if I had verify the iso? Are Qubes Repos different from the iso, or complements for the software? Qubes was created in September 3, 2012. What has happened with the other developers of 2012 (I do not see in your web)? All the instructions are for apple users? It because it is writed "sudo" in the steps. "Untrustworthy firmware. (Firmware can be malicious even if the drive is new. Plugging a drive with rewritable firmware into a compromised machine can also compromise the drive. Installing from a compromised drive could compromise even a brand new Qubes installation.)" I read article of badusb, but what usb do you recommend (because I do not find)? Curious question: what the people is normally asking when sending an email to business inquiries?

Hi, has anyone tried running Qubes on Dell Vostro 5581 laptop? I've been using a different Dell laptop until now, but I may need a replacement and this seems reasonable. The specification seems reasonable - i5-8265U does include the VT-x/VT-d features, it should have Intel 9560/9462 wifi, which seems to be supported since kernel 4.14. Dell does not offer it with Linux, though, so I wonder if there might be some gotcha. thanks Tomas -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
