How to use RDC with VirtualBox and OSX - virtualization

I'm trying to do some local RDC testing using VirtualBox. The host is OSX.8, the VM is ubuntu, and VirtualBox is version 4.1.22.
The VM starts fine without any problems. I shut it down and choose "Enable Server" from the Remote Display section of the Display options and start again, and again it starts fine. Note that the port is left default and the authentication is "null".
I start Microsoft's RDC (v2.1.0) and type in 'localhost' and get: You were disconnected from the Windows-based computer because of network problems.
I try 127.0.0.1 and get the same error. Then I type in the IP of my (host) computer and get the same error. I know the loopback address avoids the firewall but I turned it off anyway and got the same error.
I get the same error whether I'm using NAT networking or bridged. What am I doing wrong?
I should note that this is a vanilla install of VirtualBox and I haven't added any extensions or guest additions or anything like that.
Seems I'm doing everything right. What am I missing? Thanks for the help!

Problem Solved! You have to install the "VirtualBox 4.1.22 Oracle VM VirtualBox Extension Pack" (available on the VB download page) to make RDC work. I wish it would tell you this when you click "enable server" but I guess that's asking too much. I hope this helps someone else.

no internet on cloned virtual machine (Vmware workstation)

so i setup a centOS vm in VMware workstation, installed qradar..everything ran fine. I call this vm as QR1.
I was able to use qradar console on QR1 from my host machine, the internet works perfectly fine in QR1.
I make a full clone of QR1 called it QR2.
I boot it up and only running QR2 vm (QR1 is closed) but there is no internet on this vm. Even though all the network setting are same as QR1 and QR1 works just fine(i double checked).
QR2 has same adapter, same ip, same gateway and dns as of QR1 but it doesnt work...
previously i was thinking that i cannot have them both running at same time but QR2 just doesnt connect.
I am also not able to ping QR2 from my host and other way around.
What could be causing this ?
According to this vmware link reference, try these steps:
To change the MAC address of the Linux operating system:
Connect to vCenter Server using the vSphere Client Right-click the
virtual machine and click Edit Settings. Click Network adapter and
note the MAC Address.
For example, you see a MAC Address similar to:
xx:xx:xx:xx:xx:xx
1.Power on the Linux virtual machine.
2.Open a console and log in as root.
3.Change directory to etc/sysconfig/network-scripts.
4.Edit ifcfg-eth0 using a plain text editor and update the MAC address to reflect the MAC address in Step 3.

Hyper-V Enhanced Session Mode Does Not Work

I am new to virtual machines so pardon my ignorance.
I have a host machine running Windows Server 2012 R2 and I'm trying to run a VM with Windows 8.1 Enterprise using Hyper-V. I need to be able to use USB devices on the VM.
Please check screenshot for the Hyper-V settings and the VM settings. The VMConnect does not have 'Show Options' to select local resources.
I tried using Remote Desktop Connection to the VM but nothing happens when USB devices are plugged in the host machine.
Not sure what I'm missing here.
Any help in fixing this will be greatly appreciated. Thanks!
Hyper-V Settings
VM Settings
If the USB device you want to use in the VM is a USB memory stick share it with the RDP local resources option as a Drive instead of the trying to replicate the USB port itself.
Eg:
There is a dependency(XRDP) to be installed in order to enable Enhanced Session Mode. Please follow the following steps or watch this video for more clarity.
Visit https://www.youtube.com/watch?v=LS2m6iyG7_M&ab_channel=VikeshYadav
On hyper-v linux machine:
git clone https://github.com/Microsoft/linux-vm-tools
cd linux-vm-tools/ubuntu/18.04/
sudo chmod +x install.sh
sudo ./install.sh
On windows machine:
set-vm -VMName ubuntu -EnhancedSessionTransportType HvSocket
I've got Win8.1 guest system (1 gen VM) and Win10 as host. Tried pretty much everything, but wasn't able to enable Enhanced Mode (simply grayed out all the time), unless I enabled RDP connections in the guest system (Control Panel, Allow remote access to your computer). After this change VMConnect with ability to share local resources appeared on attempt to connect to the VM.
Hope this helps all the people who find this thread while googling.

Can't access SVN on CentOS 7 VM in VirtualBox

I installed VirtualBox on Windows 7, and created a virtual machine, where I installed CentOS 7. Then in CentOS 7 I installed CollabNet Subversion Edge, following this information as a guide and
performed all the steps provided there, but I can not access the server.
The installation should be performed on a desktop machine and the server I'm trying to access from a notebook, which is connected to the same network as the desktop machine. Also obviously, as the network has a proxy to surf, I had to configure it, and doing well because I can surf the internet and others. It's using 'Bridged Adapter' networking in the VM settings.
Can you think of any idea why I do not have access? Any help is welcome.
I found a response similar to what I'm looking for, but do not quite understand what it says. I'm only in CentOS7 enp0s3 interface, and there is collabnet running, not running on another interface.
NEWS:Gain access the server using its IP (172.x.x.x:3343/svn or 172.x.x.x:18080/svn), but not by name. Maybe there is a problem in the computer name, applies only to Windows, and CentOS running on the virtual machine, use another computer name. Can it be? If so, you know how to identify such equipment?
Looks like a firewall issue. Try to run following commands:
firewall-cmd --permanent --zone=public --add-port=<dst_port>/tcp
firewall-cmd --reload
Hope this helps

Netbeans IDE8 Glassfish 4, GlassFish Server: Administrator port is occupied by null

I just downloaded Netbeans IDE7 with the Glassfish 4.
I just made a project to test it out and see how it goes, and I got this error right from the start:
Could not start GlassFish Server: DAS port is occupied while server is not running
[location]: Deployment error: Could not start GlassFish Server: DAS port is occupied while server is not running
See the server log for details.
BUILD FAILED (total time: 1 second)
I have reinstalled it three times, with the Glassfish and without and then later add it to Netbeans, i changed the domain.xml name="admin-listener" port="4848" to something different
i did this cmd code netstat -aon | find ":80" | find "LISTENING" and closed the programm.
i ran as administrator i think i did almost everyting but it wont simply run, and it keeps returning to the same error
usually i would have given up but this software is required for a school project.
i will try everything.
i hope someone can help me.
Thx in advance
You have to find the process that has taken the port you need. You can try finding it by running the terminal with the command:
netstat -aon | find ":80" | find "LISTENING"
Find the information you need and than kill the process with specific PID in Task Manager.
I hope you find this useful,
Thanks.
A few points:
Why not download NetBeans 8 that also includes GlassFish 4?
Assuming that you have successfully figured out that no other process is listening on port 4848, then Which version of the JDK are you using? Can you try JDK 7 if you are using JDK 8?
Looks like you are not alone - see NetBeans bug 237477.
Note that this isn't the only problem. I run on a Mac and can use the asadmin start command successfully on the remote server. IF I try to start it from NetBeans, it gives me this message.
One hint might be that the domain.xml file is set so that the listening port is 9090, the properties screen for the remote server, which I entered 9090 for, tells me the HTTP port is 23043. I can't edit it. Everytime I try to create that remote server it sets it to this value. The server will run fine if I start it by hand on the remote server, but NetBeans doesn't think it is running.
This occurs because I had to select domain2 because NetBeans says domain1 is already registered on my local machine. I wanted to have a local domain1 and a remote domain1 that are identical so I can test locally, and then deploy remotely.
This error message could be misleading, because it is the same when IP adress of glassfish server in netbeans settings is wrong (not port).
By my experience with this over win 8.1 + Netbeans 8.0 + Glassfish 4.0
The problem resides in permission of folder in windows that block the server execution
I solve the problem changing the permission of the glassfish/domain/domain1 folder for xxxx/user to totalcontrol
If this not solve your problem, try launch the server over console:
asadmin start-domain --verbose
And read the exceptions to try solve the problem.
-EDIT:
Reading other post to try help:
like this: Glassfish server started failed in netbeans 6.9
Or check your firewall:
allow >> C:\Program
Files\glassfish-X.X\glassfish\modules\glassfish.jar
In my case when using the command
netstat -aon | find ":4848" | find "LISTENING"
I noticed that one process was occupying this port. When checked what it was I noticed it was VMWare NAT controller, because I previously had configured a network adapter to listen to this port.
Just stopped all VMWare related services (in my case I didn't need them for development purposes), and solved the problem.
Go to Task Manager -> Services -> Stop Process whose PID IS 3136,2268,2468 ,23.... and near Range in PID. All processes near to the web server's PID.
It works for me on Windows 8.1 pro & Windows 7.
I had the same error message.
Turned out it was caused because my firewall blocked port 4848
May be late but I solved this issue by deleting the app server from the Netbeans and by adding it again. In my case Netbeans 8.2 and Payara 4.1 instead of Glassfish.
If you changed the host of Glassfish server then set it to localhost it should work.

Accessing documents on a http server running in a virtual machine

I run Windows 7 as my main OS, and for development work I installed CentOS on a virtual machine under VirtualBox. Everything is installed, including httpd and php with mysql, but I can't figure out what IP to use to gain access to the server.
For example, I used to have XAMPP installed on 7 and I just used "localhost" to get to the servers document root, but I have no clue what it is for the virtual machine.
I have tried "locahost", "192.168.11.2" (my address on the network) and my own IP address and I can't seem to get it working.
Any help would be appreciated. Thank you. :)
I don't know VirtualBox, but can you do an ifconfig from the terminal window to your VM. If it doesn't give you a terminal window, your CentOS setup probably does DHCP to get an address. Browse to the web interface of your home router (192.168.11.1?) and check the DHCP clients table to see if it registered and get its address.
