USB microphone on remote desktop doesn’t appear/record (but video does)

I have the following scenario:

  • an USB Microsoft LifeCam webcam with working audio/sound
  • Target Windows 10 PC where the webcam is plugged in (target/local)
  • Source Windows 10 PC from where I am remote desktop-ing (source/remote)

Now, the issue is the following: The webcam, which does appear in device manager, whichever way I connect to the remote computer, is not able to be used as recording device, unless I turn off entirely (both input and output) the audio redirection.

enter image description here

So, we have these cases:

  1. Complete audio redirection:

    • Remote audio playback: Play on this computer
    • Remote audio recording: Record from this computer
    • Result: doesn’t use any of the remote’s input/output devices, but webcam video stream still works.
  2. Just audio playback redirection:

    • Remote audio playback: Play on this computer
    • Remote audio recording: Do not record
    • Result: no microphone/recording capability, but playing sounds from target PC on the local PC works; webcam video stream still works
    • I can only play sound from the remote PC, but I cannot do any kind of recording from the microphone:

enter image description here

  1. No audio redirection:
    • Remote audio playback: Play on remote computer
    • Remote audio recording: Do not record
    • Result: uses just the remote audio streams, so nothing is able to be heard through the remote connection; webcam video stream still works
    • I can fully see all the recording devices, just like I’d be on the PC itself: enter image description here

So, my issue is with case #2, I want to hear the remote sounds through he remote connection, but the microphone should be the one that comes with the webcam, for some reason it’s not listed, even though the webcam itself still works in any of the cases.

How to use Jekyll locally to create/edit posts on remote WordPress?

How do I use Jekyll on my local machine to create/edit posts on my remote WordPress blog? More specifically:

  • I want to write posts in plain text, use Jekyll’s markup parser to create HTML, and then post the resulting HTML to my WordPress site.

  • If I edit an existing local text file, I want the corresponding WordPress post edited. I don’t care if revision history is preserved on WordPress, since I plan on preserving it locally.

Rationale: I really like the idea of having a website stored/generated locally and then mirrored to a server, in part because that was the only way to do things when I first started posting to the Web.

However, I feel Jekyll’s lack of comments, trackbacks, and server-side scripting (though JavaScript may suffice) are not quite sufficient for my needs, especially since I want to avoid using third party tools such as Disqus, or even a local version of Disqus that runs in parallel to my blog.

Any help appreciated!

Accessing Windows VMs on XenServer with Remote Desktop Connection

I’ve installed XenServer 7.6 on a dedicated server and connected to internet via static public IP address given by technical support where I bought the server from. Using XenCenter I have also installed Windows Server 2016 and Windows 7 as VMs. At first because i am newbie I had problems connecting Windows Server and Windows 7 on internet, but I fixed that using 2 other static public IP addresses given by the technical support and I set to those two VMs. Is there a way accessing VMs on internet without these IP addresses? Now, I have installed Hyper-V on Windows Server 2016 and there I plan to install Windows Server 2012. Can I access that Windows Server 2012 using Remote Desktop Connection? I plan to do something like this: XenServer -> Windows Server 2016 -> Hyper-V on Windows Server 2016 -> Windows Server 2012 (internet connection and remote desktop connection)

How to: remote encrypted filesystem in file?

I want to create a small (~200MB) encrypted filesystem inside a regular file to keep it on my VDS, but be able to mount it locally: all decryption must be done by my local host.

This is my current sulution:

  1. Make random 200MB file: dd if=/dev/zero bs=1M count=200 of=~/zzz
  2. Initialize it with LIKS: cryptsetup luksFormat ~/zzz
  3. Open LUKS device: sudo cryptsetup luksOpen ~/zzz sss
  4. Make filesystem on it: sudo mkfs.ext4 /dev/mapper/sss

Now I can close LUKS device and:

  1. Put it to my VDS.
  2. Mount directory containint it on local folder using sshfs
  3. Open LUKS device from that local folder
  4. Mount LUKS device to another folder /mnt/sss and use this path to access to my data.

But this seems overcomplicated. I don’t need SSH to encrypt my data: LUKS already did that and I can transmit parts of file zzz without any encryption. So I want some special network protocol that consider my remote file zzz as block device and transfer blocks of that device to my local PC. The ext4 will take care of network failures: connection lost will be considered by ext4 as ordinary power failure.

iOS 12.2 Control Center Remote Control Finds no TVs

We have two Apple TV 4s and a number of iOS devices. After the iOS 12.2 update, my iPhone XS would not find the TV called LIVING ROOM but would work with PORCH just fine. I uninstalled the Remote app, and restarted my Apple TV and my phone. Now, my iPhone does not see any Apple TVs in the house, even after reinstalling the Apple TV Remote app (which does work without any problems).

LIVING ROOM shows up just fine on my iPad. Both TVs show up on my wife’s iPhone X.

I am open to suggestions for further troubleshooting that are short of restoring my iPhone from backup. I would prefer not to reset iPhone Networking Settings unless somebody is pretty sure that is likely to fix the issue.

Problem exporting vector graphics (PDF) in Mathematica Notebook Front-End using remote kernel on linux

I’m not being able to export vector graphics images (especially PDF) in a Mathematica Notebook Front-End in Windows 8.1 using a remote kernel on a Linux server.

I can, however, export Raster Image Formats without a problem.

One interesting thing to point out is the fact that when accessing the server directly via ssh command line, launching Mathematica kernel and executing the same Export command, it works fine.

Mathematica 11.3 is the version being used on both computers.

Example of a Mathematica Notebook:

SetDirectory["/home/results"]  plt = Plot[x, {x, 0, 1}]  Export["test.gif", plt]  (*Works fine*)  Export["test.jpg", plt]  (*Works fine*)  Export["test.png", plt]  (*Works fine*)  Export["test.pdf", plt]  (*Does not work*)  Export["test.eps", plt]  (*Does not work*) 

Unauthorized Remote Access

How can I find details on whoever is remotely accessing my pc? It was given to me by a computer programmer and I am certain he is still accessing it remotely. Capturing screenshots, routing emails, photos, PDFs, etc… how can I shut him down and possibly remove him all together? Is there software or anything I can use to log his activities? Thank you

Windows Server 2012 R2 default resolution for remote connections

Couldn’t find the accurate answer searching for a bit, so here it goes.

After getting the brand-new server up, there were 5 user accounts created for remote desktop usage. Now the problem is, for two of them the Server seems to assume default 1920×1080 resolution (resolution of device which was first to connect to the user, looks like), and for the other three it is 1366×768.

Now, when people started to use all of the remote accounts for work, the two accounts with 1920×1080 default resolution turn out to be blurry and hard to work with for people, who connect from devices with maximum resolution of 1366×768 (provided by company, so there’s no changing that).

So, the question is if there is a way to change the default resolution for all of the users (or separately for every single on of them) server side?

The perfect solution is to lower the resolution enforced by server for those 2 users, so both the 1366 and 1960 users can work remotely on those user accounts.

Those 2 things I’ve already tried didn’t help:

  • changing the maximum resolution to 1366×768 in local group policy

  • searching registry for XResolution and YResolution entries and changing 1920×1080 to 1366×768

The general feedback of the two users that connect to 1920 with 1366 maximum resolution devices beside the resolution incompatibility they reportedly also have some performance issues with accounting programs they use (no such issues on other 3 user accounts, might be unrelated though).

Any feedback is appreciated. Cheers!

How to use a remote computer to surf the internet


There are two computers,A & B. A & B can remote desktop connect each other. But A can not connect the internet,while B can. How A can use B network to surf the internet?

Question in real life:

I am a college student.Four classmates are living in the dor.Each person has to pay for the network fee about 10$ a month(really expensive for us,the speed is only 2mb/s).We have tried many ways like set up a router,interchanger.But all failed. Each person has their unique account and password,everytime we log in we have to input the password. Luckily,we found that the computer in our classroom`s network is really fast speed but the cpu is really slow.So can we use the computer in classroom to let the computer in our dor to surf the internet?

Thank you very much !
