I am trying to connect to a remote system which has CentOS running on it from a Windows machine. I am getting the following error:
My remote computer is on and is available on the network. I tried following the steps mentioned on this website http://www.techotopia.com/index.php/Remote_Access_to_the_CentOS_6_Desktop to enable remote access on centos as well.
Currently I can access the remote sever through commandline utility like Putty only.
I use VNC for remote GUI admin work on CentOS device's from windows its nice and easy to set up and use, below are links to CentOS 6.5 set up guide and 7
https://www.howtoforge.com/vnc-server-installation-centos-6.5
https://www.howtoforge.com/vnc-server-installation-on-centos-7
Let me know how you get on :)
As posted by PaulM, I followed the steps in the website to install VNCServer on the centos machine.
To connect from my linux machine, I wrote the following commands:
vncviewer
IPAddress:5901
Adding the port number specifically made it work
CentOs to centOs Only
No Need Any Softwares Already Centos have TigerVnc Viewer
1.Enable Remote desktop in your centos system
Goto System-->Preference-->Remote Desktop
**i.Enable allow other user to view your Desktop**
**ii.Enable allow other user to control your Desktop**
**iii.You must confirm each access to this machine allow or cancel**
**iv.if you ask any password to enable and type your password**
Notification Area:
Some one connect your system its enable to shows the icon on top panel.

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.
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.
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 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 have Installed GTK on a Linux machine.
I am connecting To Linux Machine from a Telnet Session to compile the GTK programs
From A Windows Machine. I am using Cygwin on Windows Machine. but i am not able to see
GUI output of my GTK program on my Windows Machine.
When i run program from my terminal i get this error:
(helloworld:22576): Gtk-WARNING **: cannot open display:
I tried solutions from every answer posted, but no use now i am getting following error:
$ ./helloworld
Invalid MIT-MAGIC-COOKIE-1 key
(helloworld:22710): Gtk-WARNING **: cannot open display: 172.25.0.161:0
and i am getting following error on my Cygwin console:
client 6 rejected from IP 172.25.0.91 Auth name: MIT-MAGIC-COOKIE-1 ID: -1
You must set the DISPLAY variable in your telnet session to the IP address or DNS name of your Windows machine and append ":0"
export DISPLAY=windows.your.domain:0
And you must start an X server on the Windows machine (comes with Cygwin but you must start it).
You need to run the X window system (install with Cygwin) on your Windows-box and enable remote connections (probably with xhost). Set the DISPLAY-variable on your Linux-box to the address of your Windows-box and :0, as such:
export DISPLAY=192.168.1.123:0
I can recommend using ssh rather than telnet, for security reasons. In this case you do not need to enable remote connections with xhost, and you do not need to set the DISPLAY-variable. You only need to enable X forwarding.
You should install X-server on your windows machine and make sure you have DISPLAY set to yourmachine:0 or something like that. Or better yet use ssh instead of telnet (e.g. putty) and tunnel your X connection. You'll have to do a bit on your own research, though, because the complete answer would be a lengthy one.
Install an small X server on Windows XMing32, then run it, use putty as a console client, and check "X11 Forwarding" in Connection->SSH->X11.
Unfortunately, X11 Forwarding is not available through Telnet, you must run a SSH server on the target Linux and connect through SSH. (See if /etc/ssh/sshd_conf requires enabling X11 Forwarding too).
