I have downloaded Genymotion and installed it with Oracle Virtualbox 5.0.10 on Windows 10/64bit.
I keep getting the errors:
Virtualization engine not found.
Cannot rename this connection. A connection with the name you specified already exists. Specify a different name.
I've tried uninstall/reinstall, deleted unused network adapters in device manager. I'm at loss.
Thank you all in advance for any help/idea.
You must go the VirtualMachine preferences under File in the menu. Then choose the Network setting, then Host-only Networks.
You can use the - button to delete all of the Ethernet Adapters that you have there.
Then create a new one and use the following settings:
IPv4 Address : 192.168.1.201
IPv4 network mask : 255.255.255.0
Then in the DHCP server tab:
Address: 192.168.1.100
mask: 255.255.255.0
Lower address: 192.168.1.101
Upper address : 192.168.1.199
Check to see which Ethernet adapter # you have now set up - this might be important later on.
Click OK for all the open boxes or save whatever you have.
Then try and run genyMotion again.
This worked for me.
There is one more thing you may have to do if this still doesnt work.
Go to Network and sharing centre . Change adapter settings and disable all the Ethernet connections EXCEPT for the Ethernet adapter you have just created.
I hope that helps

Almost every GNU/Linux system comes with an installer package for Oracle VM VirtualBox.
Browse for the Oracle VM VirtualBox installer in your directories.
If you do not have the installer or if you need to install a specific version, download and install VirtualBox for Linux hosts from the Download VirtualBox page.
When installing VirtualBox, in the Custom setup window, make sure VirtualBox Networking is enabled.
Go to the Genymotion download page and download the Linux package corresponding to your system.
Run the following commands:
chmod +x <Genymotion installer path>/genymotion-<version>_<arch>.bin
cd <Genymotion installer path>
./genymotion-<version>_<arch>.bin -d <Genymotion installer path>
Run Genymotion using the following command:
cd <Genymotion installer path>
./genymotion

I'm doing some Ruby on Rails development on a WSL 2. The rails app connects to a MySQL server running on my Windows host. When I used WSL 1 it as easy to set the host to 127.0.0.1 but on WSL 2 I have to use the nameserver written in /etc/resolv.conf
But I found out that IP address written in resolv.conf changes on reboots.
Is there a way to set a static IP address for WSL 2 ?
You can consider ocroz/wsl2-boot (see INSTALL for installation instructions)
After running wsl-boot command:
The WSL network is configured as per its predefined definition always (Windows side),
All WSL hosts are configured with their predefined static IP always (Linux side),
All WSL hosts and connected Hyper-V VMs can talk to each other always,
The DNS resolution works however you are connected to Internet or VPN,
You can SSH to WSL host without any delay.
Dec. 2022, microsoft/WSL issue 4210 also adds:
With the latest Windows 11 (22621+), you can already specify the network adapter you want to use for WSL2 in .wslconfig:
[wsl2]
networkingMode=bridged
vmSwitch=my-switch
ipv6=true
So, now you can create a Hyper-V external virtual switch for WSL2 and fix the IP address, no other scripts are required. It works out-of-box.
The same thread adds:
Create a vSwitch in Hyper-V，I Use Hyper-V Gui to do this. Hyper-V has three types of virtual switches -- external, internal, and private.
I choose the "external" type , which is bridge type, the same as VMWare workstation.
set this config in .wslconfig
I find the IP change to the network of my home router，which is replace the old of eth0.
You can set DHCP in you home router, then Fix the IP of the bridge.
To sum up, in the case of bridge, it is essentially DHCP , and whether it is fixed or not depends on the DHCP server.
If you don't want /etc/hosts, /etc/resolv.conf to change after restart, you can create
/etc/wsl.conf
[network]
generateHosts = false
generateResolvConf = false
Question: How do I get CDK to work on the corporate laptop using virtualbox without running into the 'could not find mathcing ip for mac' issue?
environment: Windows7, CDK 3.2.0, Virtualbox 5.0.x/5.1.x various versions tried. Key callout, corporate machine has VPN software (cisco anyconnect) while home pc does not, home pc works fine. Issue happens regardless if using VPN or not. Virtualbox (all versions) proven to work using vagrant.
Key finding:
minishift ssh -> functions, doing an ifconfig returns eth0 with a 10.0.*
network, instead of the expected 192.168.99.* network segments configured
for virtualbox network host adapters. Explicitly using minishift config set
host-only-cidr 192.168.99.1/24 with matching virtualbox host adapters
doesn't change outcome
Details:
c:\devrh\cdk\bin>minishift version
minishift v1.7.0+204ce19 CDK v3.2.0-1
c:\devrh\cdk\bin>minishift start --vm-driver=virtualbox -- Starting local
OpenShift cluster using 'virtualbox'
hypervisor ... -- Starting Minishift VM ............................ FAIL
E1108 10:27:05.991687 3128 start.go:356] Error starting the VM: Error

address 0800279fa156. Retrying. Error starting
the VM: Error configuring authorization on host: Could not find matching IP
for MAC address 0800279fa156
corporate workstation has the issue, home PC does not.
Minishift delete and restart, same issue (different MAC address, but same issue).
Virtualbox remove all host adapters, minishift delete, restart (which auto-creates new host adapters), same issue.
Minishift --profile approach, same issue.
Uninstalled virtualbox, installed the version from the RHDevSuite installer with the CDK from the installer, all steps tested with that combination as well, same issue.
Additional notes, Virtualbox is working fine with vagrant (static IP’s in vagrant files), virtualbox/vagrant combo works on both corporate and home machine without issues.
I currently have an html file on a remote unix server that I ssh to. I have been using SFTP to constantly transfer it to my local machine to view it after my edits, but I am tired of this.
What is the best program/method for Mac users to have a browser window view of the html file that is stored in a remote unix server? Or is there an ssh client that can easily edit html files?
It is possible, but with some playing around on the server.
Once you have ssh'ed into the server, install a web server in that box.
Say the file is named index.html, you should make it available at the URL http://localhost:8000/index.htmlor port number can be anything.
The simplest method I can think of starting a web server at that location is
cd /directory/where/html/is/present
python -m SimpleHTTPServer 8000 # For python 2
python3 -m http.server 8000 # For python 3
This works provided python is installed on the server. It should not be that hard to install it as python is available from almost every package manager in every flavor of linux.
Now that html is available at python
http://localhost:8000/index.html
on that machine.
But we have not yet configured the browser in such way.
To do that you need to ssh into the server again, but with a -D option this time
ssh servername -D 7000
-D specifies application level tunneling when connecting via ssh
Then in Firefox, preferences/options -> Advanced -> Networks -> Connection Settings -> Choose Manual Proxy configuration
SOCKS HOST should be localhost , port no 7000.
Then the html should be directly available at
http://localhost:8000/index.html
in your Firefox browser.
This feature is only available in the Firefox browser.
You can mount the remote directory with sshfs which gives you easy access to all the files.
E.g.:
sshfs user#server:/directoryToMount /localDirectory
I am trying out a "Hello World" exercise for GCE. First, I went with CentOS Image, added the instance, installed Apache, added the Firewall. All looks good as far as configuration is concerned. When I try to access the web page from outside, it cannot reach the page.
The Local Apache Server is running, from the local instance I can do a curl and all is well.
On the other hand, if I try out the same exact steps with the Debian distribution, everything works smoothly.
I saw another post that mentioned about additional firewall settings but I have not tried that out and I am not sure why it should be done either.
Can anyone explain if the CentOS setup does need additional Firewall settings and what those are?
CentOS defaults to a restrictive operating system level firewall (using iptables), while debian defaults to a permissive one. You can relax the firewall rules on CentOS as well. When running on Compute Engine, the service level firewall will only allow connections from the internet via configured ports.
To relax the CentOS firewall:
$ sudo iptables -D INPUT -j REJECT --reject-with icmp-host-prohibited
Then test that your connections work as expected. To save this configuration across system reboots:
$ /sbin/service iptables save
See the IPTables HowTo on the CentOS wiki for more information about working with iptables on CentOS.
You need free the ports in the cloud console.
Watch this video that explain the proccess.

I have looked at lots of forms and threads on this site.
First I installed MySQL using msi installer.
Configuration settings:
- detailed configuration
- developer machine
- multifunctional database
- initial path
- decision support
- enable tcp/icp networking, port 3306, add firewall exception for this port.
- enable strict mode
- best support for multilangualism
- install as windows service, include bin directory
- entered root password.
Then when I clicked execute it freezes after writing the configuration file.
- I closed that window.
Then when I opened MySQL Command Line Client and typed in the root password i get this..
ERROR 2003: Can't connect to to MySQL server (10060)
I then opened up command prompt and typed.
C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld --install
got message:
Install/remove of this service denied.
I ran the initial configuration as administrator and I have checked that port 3306 is open.
Hope this is detailed enough.
Thanks.
I would suggesting uninstalling them all and reinstalling them with a package such as LAMP (for linux) or XAMPP (for windows). Much easier to install and set up, tutorials everywhere.
Can you get to the MySQL server instance config wizard in start menu
Is the MySQL service running?
whats the conf file look like?
