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

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!

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.
I am running a Django server on a redhat computer. I can remotely connect to the computer via ssh connection, so I am assuming there is no firewall issue. However, when I execute the following command (which supposedly should make the server publicly available)
python3 manage.py runserver 0.0.0.0:8080
The server is not reachable from any other computer. Locally (from the redhat machine itself) I can see the server is running.
I am new to redhat, so if there is any other information I should provide, please let me know.
So far, I have found that I can make my server reachable using localtunnel, however, since it changes the url, I prefer to solve the issue some other way.
UPDATE: the problem had nothing to do with Django. What made confusion was that the server was running with no problem and turned unreachable with no specific reason.
Anyways, I needed to add some configurations (found in here) to make port:8080 reachable.
Open the port 8080 with
firewall-cmd --zone=public --add-port=8080/tcp
To add it permanently to the system, add --permanent like so:
firewall-cmd --zone=public --add-port=8080/tcp --permanent
I am running Centos 7 x86-64. I installed a guest (again Centos 7) through kickstart as an exercise. I prepared my kickstart file, I validated it and I launched with virt-install.
If something went wrong with the network configuration (During install I got no problem, I created a local repo on Host FTP server as source for the install) how can I connect to the machine?
Only SSH or virsh foresee some other connection method?
How can I find my machine running network configuration from outside?
I am running a barebone Centos7 installation so only command line, no graphical interface at all.
Thanks,
M.
You can ssh to your physical host from another one having graphical interface with X forwarding enabled (ssh -X machinename), and look at the the VM with virt-manager
You will need X running on the machine you're connecting from. For Mac OS it's XQuartz
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.
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.
