I am trying to setup a wifihotpot on my laptop in ubuntu 18 running as a Windows Subsystem for Linux (WSL). (Terminal only)
Following basic tutorials I wanted to run the following command:
~$ nmcli device wifi hotspot con-name my-hotspot ssid my-hotspot band bg password 123456
Error: Could not create NMClient object: Could not connect: No such file or directory.
Trying to start the networkmanager also fails:
~$ sudo service network-manager start
* Starting network connection manager NetworkManager [ OK ]
~$ sudo service network-manager status
* NetworkManager is not running
I tried the networkManager after installing network-manager:
sudo add-apt-repository ppa:nilarimogard/webupd8
Is there another way to create a wifi hotspot from Ubuntu running as a WSL? Or does it not have the right access to the windows host to pull it off?
at this time, I don't believe it is possible according to https://github.com/microsoft/WSL/issues/2438. They designed WSL to ignore calls to set interface properties. So nmcli and other commands that changes interface properties are not working, they marked it as a bug and will fix it in the future.
"WSL currently ignores the call (which was intentional at the time of the design) to set interface properties" - sunilmut
I hope to help in some way :)

I have a run configuration setup for a server tool. I want to run it in WSL2 environment from an Intellij run task. This works great but I need to manually set the Windows host IP whenever I restart the WSL2. To get the host IP I want to use this grep command:
grep -o -P "(?<=nameserver )[0-9\.]+" /etc/resolv.conf
I played with the configuration and tried something like this
This didn't work, because the grep command didn't get executed. It worked as expected when I used it in the console.
Trying the same thing with the enviroment variable didn't succeed as well.
I saw that it is possible to setup a "before run task". Maybe it is possible to do it with this option?
I am running a virtual environment on CentOS with podman.
When I used the --net option of the podman run command, I get an error.
[user#server ~]$ podman run --net slirp4netns:port_handler=slirp4netns -p 1080:80 -d --name web nginx
Error: cannot join CNI networks if running rootless: invalid argument
Is this option unavailable?
Or is there a problem with the way the options are specified?
Please tell me solution.
I used this site as a reference for the command.
This is the configuration of the server.
[user#server ~]$ cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
[user#server ~]$ podman -v
podman version 2.0.6
The port_handler option requires Podman >= 2.1.0, which isn't released at this moment: https://github.com/containers/podman/commit/d86bae2a01cb855d5964a2a3fbdd41afe68d62c8
You can use that option if you compile Podman from its master branch.
I find this link quite helpful to see rootless communication :
https://www.redhat.com/sysadmin/container-networking-podman
https://podman.io/getting-started/network
I am not sure if you have seen this link before or even if it is helpful to you at this instance. But, in view of helping others out, I think the blog post quotes the following helpful statements:
Note: All podman network commands are for rootfull containers only.
Technically, the container itself does not have an IP address, because without root privileges, network device association cannot be achieved
When using Podman as a rootless user, the network is setup automatically. The container itself does not have an IP Address, because without root privileges, network association is not allowed. You will also see some other limitations.
I'm new to Chef and I have stuck in a problem. I'm using AWS Chef Automate Server and EC2 ubuntu instance as Chef Node. My workstation is local machine where I have installed ChefDK on windows. I have successfully configured the Chef server with ChefDK.
When I bootstrap the node using Knife Bootstrap command, it bootstraps the ubuntu node but shows this error in the end cannot create /etc/chef/trusted_certs/opsworks-cm-ca-2016-root.pem: Directory nonexistent
The command I used here is knife bootstrap myEC2PublicIPHere -N UmaidNode1 -x ubuntu --sudo --run-list "recipe[nginx]" -i .chef/my_key.pem.
After that I added some other cookbooks in the server and run Knife ssh command from my windows workstation to run Chef-client on the node, but this command is not working. I have tried it with different attributes, but always the similar issue FATAL: 1 node found, but does not have the required attribute to establish the connection. Try setting another attribute to open the connection using --attribute.
The command I tried here is knife ssh 'name:*' --attribute myEC2PublicIpHere -x ubuntu -i .chef/my_key.pem 'sudo chef-client'.
Furthur upon running this command knife node show UmaidNode1, it shows the data about node where IP is blank. I don't know why it is not getting this IP here. Showing the output Node Name: UmaidNode1 Environment: _default FQDN: IP: Run List: recipe[nginx], recipe[apache] Roles: Recipes: Platform: Tags:
enter image description here
The issue is finally resolved. I don't know why, but the problem was with the ChefDK version. I was using the latest version 4.8.23. It always creates directory /etcchef but the chef searches for all files in the directory /etc/chef. So it was unable to get the files like client.rb etc.
NOTE: I even make the required /etc/chef directory by myself, but it didn't work.
I installed an older version of ChefDK and now it's working fine.
Host OS: Windows 10
Vagrant: 2.2.4
VirtualBox: 6.0.6 r130049
When I run vagrant up, it prints this error message:
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
setup
Stdout from the command:
Stderr from the command:
bash: line 4: setup: command not found
The machine can be booted normally and SSH from my host to Virtual machine is OK but the synced folder is not working. I know this may not be a critical issue but still feel frustrated as I use my host machine to develop codes and "sync" these codes so that they can be loaded in my virtual machine.
Any advice is highly appreciated.
ps: When I boot a full UI virtual machine (different from my above mentioned) from my VirtualBox directly, it seems OK to have a "sync" directory and the VBGuestAdditions can be installed without errors.
It is a bug in VirtualBox 6.0.6 and it still exists in 6.0.8. The solution is to downgrade your VirtualBox itself and the Guest Extensions to 6.0.4.
EDIT6: submitted an official path bug: https://github.com/mitchellh/vagrant/issues/7512
EDIT5: When I do vagrant destroy and vagrant up, everything works easily. But when I turn off the VM and turn it back on (you have to restart your PC some day), it won't work again. Either the sequence for vagrant up when the VM is created is bugged or VirtualBox is bugged. Destroying and rebuilding the VM is not the option, cause the DB migration and everything takes ~30 mins at least. Either way, DON'T USE VAGRANT ON WINDOWS 10.
EDIT4: I downgraded to Virtual Box 5.0.0.10, that fix the wrong path problem, but the error Command not in installer persists.
EDIT3: When I went into vagrant up --debug, I found out that it cycles. It gets into line
INFO subprocess: Starting process: ["C:/Program Files/Oracle/VirtualBox/VBoxManage.exe", "showvminfo", "8aaee3a3-806f-4
8ad-9928-91e2b7baba5d", "--machinereadable"]
and then it does
INFO subprocess: Command not in installer, restoring original environment...
The path to VM uses forwards slashes instead of backslashes. Is this a bug? Is there a way to manually set path to VM? I have put C:\Program Files\Oracle\VirtualBox in my PATH.
EDIT2: DON'T USE VAGRANT ON WINDOWS 10, it's bugged in many ways, also VM is not optimalized for win10 yet, you'll get bunch of issues that you won't be able to solve. Also tried the Otto from Hashicorp, not working either. Rip.
EDIT: okay, so when I do vagrant destroy and vagrant up, after 10 minutes of installation it works like a charm. But after I restart my PC or logout in any way, Vagrant is unable to connect to the VM, neither with a private key, nor with login/password. Is that a bug?
When I do vagrant up, VM starts properly, but Vagrant is unable to connect. All it says is Warning: Remote connection disconnect. Retrying...
When I try to connect via vagrant ssh, I get only ssh_exchange_identification: read: Connection reset by peer. When I check GUI of the VM, it is waiting for login, and when I login with defult login/password, it is working as intended, so the problem must be Vagrant not being able to connect to the VM.
I tried:
checking if my pc supports virtualization and checking if it is on
trying to connect with password instead of a key
configuring networking adapetrs
turning off firewall
clean reinstall
I am using Vagrant 1.8.1 and VirtualBox 5.0.20 on Windows 10.
This is my vagrant file:
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.provider :virtualbox do |vb|
vb.memory = 2048
vb.gui = true
vb.cpus = 2
end
config.vm.network :private_network, type: "dhcp"
config.vbguest.auto_update = false
config.ssh.insert_key = false
config.vm.provision :shell, path: "bootstrap.sh"
end
[Edit 17/06/2016]
The problem should be resolved with Virtualbox 5.0.22.

[Original answer below]
In contrast to my earlier answer I now don't think that I encounter the same problem as you have described here. However I still think that you encounter a different variation the problem.
As of feedback received from Virtualbox development https://www.virtualbox.org/ticket/15412 I learned that Virtualbox 5.0.20 includes changes to the NAT Forwarding Rules to address other bugs. When a VM is saved and started again, Virtualbox now removes the network cable for 5 seconds. This is supposed to trigger the DHCP client to request a new lease. This information in turn is then used by Virtualbox to infer the IP address and NAT should work.
In my particular case I encounter this problem with Ubuntu 16.04 as guest VM whereas with Ubuntu 14.04 it works. This indicates to me that the DHClient on Ubuntu 14.04 does request a new lease after the cable was disconnected by Virtualbox whereas this is not the case with Ubuntu 16.04.
In order to verify that you encounter the same problem, I wonder if you could run the below test and let me know.
Login to the Trusty VM console (i.e. the one that you get displayed when you run the VM in the foreground)
Install 'arping' (sudo apt-get -y install arping)
Create the below script 'sendARP.sh'
#!/bin/bash
IFACE=$(ifconfig | grep 'Link encap:Ethernet' | awk '{print $1}')
IP=$(ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1')
arping -c 1 -i $IFACE $IP
Make it an executable 'chmod +x sendARP.sh'
Save the Trusty VM (vagrant suspend)
Start your Trusty VM from saved state (vagrant up)
Login to the Trusty VM console (i.e. the one that you get displayed when you run the VM in the foreground)
Run the script 'sudo ./sendARP.sh'
Test whether you can connect via SSH from the remote location/ Virtualbox host
