Hello there guys i have been trying to use hcitool on mac os terminal but whenever i type hcitool scan the following error is appeared -bash: hcitool: command not found i have tried pip install hci and pip install hcitool but the following error is shown
ERROR: Could not find a version that satisfies the requirement gatttool (from versions: none)
ERROR: No matching distribution found for gatttool
please help me with this
Commands such as hcitool, gatttool, hciconfig, etc. are part of the BlueZ package which works on Linux only. MacOS on the other hand is UNIX-core and therefore the commands will not run on a MacOS operating system. There have been hacks before to get some sort of functionality on MacOS OSs but the solution is always incomplete.
Your next best bet will be to use a Virtual Machine running a Linux guest (e.g. Ubuntu) and then use the BlueZ commands from within that VM OS.
I hope this helps.
Get yourself a Docker container up and running. You can write scripts that you keep in a shared volume between the host and the container (meaning you don't have to log into the container). You can then execute those scripts from your OSX terminal, to run in the container.

I'm trying to resize a qcow2 img I created and installed a guest mac os. When I try to use virt-resize I get the following error:
virt-resize: error: libguestfs error: /usr/bin/supermin exited with error status 1.
This seems to have to do with not being able to access the kernel or wrong permissions on the kernel. I'm running Ubuntu via WSL2 and I'm not sure how to give libguestfs-tools access to the kernel WSL2 runs on. How would you do this?
This comes about because there's not really a good way (at least, not any obvious one after a bit of time with Google) to get access to the WSL2 kernel from within WSL2 without custom-compiling your own.
In lieu of that, libguestfs-tools will work just fine if you install the normal Ubuntu kernel packages and do the usual Ubuntu follow-up step for libguestfs-tools:
sudo apt install linux-image-generic-hwe-20.04
sudo chmod go+r /boot/vmlinuz-*
This will populate your /boot and /lib/modules/* directories with a kernel that will satisfy libguestfs-tools.
OK so here is what I have done so far. I installed docker for mac, and that worked fine. From there I tried to get a project up and running using docker-compose and I got the following error:
Could not read CA certificate "/Users/<useraccountfolder>/.boot2docker/certs/boot2docker-vm/ca.pem": open /Users/<useraccountfolder>/.boot2docker/certs/boot2docker-vm/ca.pem: no such file or directory
So I tried to fix it by trying this accepted answer. This is when I got another error, Host does not exist: “default”. This is when I trie this accepted answer, but when I tried to run docker-machine create default, I got this error: Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path". I am just lost at this point. Any help?
To use docker machine you need the latest version of VirtualBox, from the docker docs:
IF YOU ARE USING DOCKER FOR MAC
Docker for Mac uses HyperKit, a lightweight macOS virtualization solution built on top of the Hypervisor.framework in macOS 10.10 Yosemite and higher.
Currently, there is no docker-machine create driver for HyperKit, so you will use virtualbox driver to create local machines. (See the Docker Machine driver for Oracle VirtualBox.) Note that you can run both HyperKit and Oracle VirtualBox on the same system. To learn more, see Docker for Mac vs. Docker Toolbox.
Make sure you have the latest VirtualBox correctly installed on your system (either as part of an earlier Toolbox install, or manual install).
Source: https://docs.docker.com/machine/get-started/#prerequisite-information
OK so I found a solution which is probably not fixing the root issue, but it does work. To unset previous variables I ran this command unset ${!DOCKER*}. This worked, but then I had to run it every time I started a new terminal session, so I added it to my .bash_profile and now I am good.
I started Docker and am now following the tutorial, but for all I know I couldn't run the docker-machine command on OS X.
The documentation states that you run the following command to create a local virtual machine:
docker-machine create --driver virtualbox manager
However, this command doesn't work in OS X (11.6), with the following error:
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
I tried to install the virtualbox; however, another page clearly states that you must not install it on your local machine:
VirtualBox prior to version 4.3.30 must NOT be installed (it is incompatible with Docker for Mac)
Note: If your system does not satisfy these requirements, you can install Docker Toolbox, which uses Oracle VirtualBox instead of HyperKit.
So I only installed Docker for Mac and not virtualbox. So what am I missing here? The example page says you can run the tutorial on OS X, so I wonder how I can proceed...
You can follow along and run this example using Docker for Mac, Docker for Windows or Docker for Linux.
I had the same issue today and resolved it by installing VirtualBox as an additional step after installing Docker for Mac (I did so with brew install --cask virtualbox)
I don't recall having to do the extra install previously, but maybe I already had VirtualBox already installed because of another tool (like Vagrant). Anyway, this is explained in the Docker Machine documentation:
If you are using Docker for Mac
Docker for Mac uses HyperKit, a lightweight macOS virtualization
solution built on top of the Hypervisor.framework in macOS 10.10
Yosemite and higher.
Currently, there is no docker-machine create driver for HyperKit, so
you will use virtualbox driver to create local machines. (See the
Docker Machine driver for Oracle VirtualBox.) Note that you can run
both HyperKit and Oracle VirtualBox on the same system. To learn more,
see Docker for Mac vs. Docker Toolbox.
Make sure you have the latest VirtualBox correctly installed on your system (either as part of an earlier Toolbox install, or manual
install).
I had the same issue. At the same spot ;-)
For me the xhyve driver, available from https://github.com/zchee/docker-machine-driver-xhyve, worked.
In short:
brew install docker-machine-driver-xhyve
You get a notice some links need to be created manually, so copy those and execute
sudo chown root:wheel /usr/local/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
sudo chown root:wheel /usr/local/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
Create:
docker-machine create --driver xhyve manager
Without VirtualBox. Im using OS X 10.11.6, too.
After updating my docker docker-machine command stopper working on my mac terminal.
So found after updating my docker I'll have to reinstall docker-machine CLI just to get the latest version.
Updated docker-machine to latest one using the command below helped me making docker-machine command working again.
base=https://github.com/docker/machine/releases/download/v0.16.0 &&
curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/usr/local/bin/docker-
machine &&
chmod +x /usr/local/bin/docker-machine

I am interested in Rethinkdb and would like to develop/test on it, but main problem is: it don't have package for windows operating system. I tried to compile from source code, that was also not possible as there was no any instruction.
What makes it so difficult to make executable for windows? Is there any alternative way to install Rethinkdb in windows OS? even very small and not that famous application has windows binary but not Rethinkdb. It is quite surprise for me. Another surprising is there are many community executable for other OS but not windows.
Thank you for understanding and waiting for good answer.
Rethinkdb just announced that it started development for Windows. Please follow
[1] https://github.com/rethinkdb/rethinkdb/issues/1100
[2] https://twitter.com/segphault/status/590633792781611009
Update:
RethinkDB announced in Windows :
[3] https://rethinkdb.com/docs/install/windows/
Cross-platform development isn't that easy. RethinkDB uses some features under the covers which makes porting it to Windows a difficult job, f.e. a Unix toolchain for the builds and Unix syscalls. For more information on that have a look at this GitHub issue. It states that Windows support is planned, but with low priority.
As a quick fix, you could RethinkDB run in a virtual machine or in Microsoft Azure. For the second one, I wrote a blog post a few weeks ago.
RethinkDB has already started development for Windows. While it's not released yet, this is how you can run it through Vagrant. See: https://github.com/gearz-lab/rethinkdb-vagrant
I'm using Chocolatey, feel free to skip steps if they don't apply.
Installing Chocolatey
Open Powershell as an administrator and run this command:
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
... now you should have Chocolatey installed. We're gonna use to install the others.
Installing Vagrant
Run this as an administrator:
choco install vagrant -y
Installing VirtualBox
Vagrant relies on a virtualization application that it calls a "provider". The default one is VirtualBox so let's install it. Run cmd as administrator and run this:
choco install virtualbox -y
Now you should be able to run the vboxmanage command. If it doesn't work, make sure C:\Program Files\Oracle\VirtualBox is in your PATH.
Installing Cygwin
We're gonna log on a virtual machine using SSH, so we need a SSH enabled terminal. For that, let's use Cygwin.
choco install cyg-get -y
Installing Cygwin packages
There'are two Cygwin packages we need to install, openssh, because Cygwin doesn't have SSH support by default, and rsync so Vagrant can use it to synchronize files between the host and the guest machines.
On PowerShell, running as an administrator, let's run these commands:
cyg-get openssh
cyg-get rsync
Cloning rethinkdb-vagrant
Open the Cygwin64 Terminal. You should now be in your Cygwin home folder, which should look like C:\tools\cygwin\home\[YOUR_USER].
Make sure you have git installed. If you don't just choco install git -y. Now, clone rethyinkdb-vagrant:
git clone https://github.com/gearz-lab/rethinkdb-vagrant.git
Now you should have a directory like this: C:\tools\cygwin\home\[YOUR_USER]\rethinkdb-vagrant.
Starting Vagrant and useful commands
From inside the Cygwin64 Terminal home directory (described in the last step), type cd rethinkdb-vagrant, now, any Vagrant commands will target cd rethinkdb-vagrant.
To setup and boot the machine: vagrant up (After this, RethinkDB is available, see next step).
To access the machine's terminal: vagrant ssh.
To destroy the machine (every RethinkDB data will be lost): vagrant destroy.
To suspend the machine: vagrant suspend.
To resume a suspended machine: vagrant resume.
Accessing RethinkDB.
Make sure you have vagrant up from the last step. Now:
For accessing the web administration tool: http://localhost:8080.
For accessing RethinkDB from a client app, the port is 28015.
I've installed rabbitmq on Mac OS X via homebrew, just a simple command:
$ brew install rabbitmq
but, when I start the server via rabbitmq-server, it occurs:
ERROR: distribution port 25672 in use on localhost (by non-Erlang process?)
I want to find some process that uses port 25672, but I can't find that really strange
anyone knows the reason, thx a lot :)
Use sudo lsof -i :25672 to find the process. sudo may or may not be needed depending on user permissions.
