I'm currently working on a virtu project for my IT school. I have this PC with XenServer only, used for the said project. I :
Placed it at my home
Connected it to my router
Deactivated DHCP for its address
Configurated the ports so I can access it from outside
Registered a dynDNS domain
Tested it : I can type the dynDNS address from outside and I see the XenServer page (Nothing but the links to XenCenter and "Citrix Systems, Inc. XenServer 6.2.0")
So I tried to register the XenServer in XenCenter and I get ERROR ! "Unable to connect to 'whatever.net'. The connection was refused. Check etc and try again."
Is there something I am missing? Btw sorry but English is not my native language.
Check your /etc/hosts.allow file. It has to contain the next line:
xapi: 1.2.3.4 your.ip.address. 192.168.10.

I am trying to deploy to my Hololens 2 and I'm trying to connect to it via wifi.
I am following the instructions here:
https://learn.microsoft.com/en-us/windows/mixed-reality/mrlearning-base-ch1
I also followed the instructions here for connecting via wifi:
https://learn.microsoft.com/en-us/windows/mixed-reality/using-visual-studio#enabling-developer-mode
I am using Master/Arm64/Remote Machine
I got the IP address for my Hololens 2 and put it in the Remote Machine Name under Project -> Properties -> Configuration Properties - > Debugging -> Remote Machine.
For authentication type, I am using "No Authentication".
The project builds successfully
Problem comes from when I try to deploy.
The error message I am getting is this:
DEP6957: Failed to connect to device '127.0.0.1' using Universal
Authentication. Please verify the correct remote authentication mode
is specified in the project debug settings. COMException - No
connection could be made because the target machine actively refused
it. (Exception from HRESULT: 0x8007274D) [0x8007274D]
I have confirmed that my machine is in fact turned on when I try to deploy.
Has anyone seen this before?
Do you have any suggestions?
My ip address, on my hololens, is not 127.0.0.1, why does it say that is my IP address? I put something completely different in Configuration Properties -> Debugging.
Make sure that you enter the IP address (machine name) in the active configuration (Master/ARM64 in your case). For the authentication type select the Universal (Unencrypted Protocol), as mentioned in the manual.
Check the IP of the HoloLens 2, which must be entered as the machine name, this can change over time.
You can find the IPv4 address under Settings -> Network&Internet -> Advanced options of the Wifi network you are connected to.
Also make sure that the PC from which you deploy the HoloLens 2 and the HoloLens 2 are in the same Wifi network.
I never figured out what caused this error, but I know how I fixed it.
Close out of Visual Studio.
Search for a '.suo' file.
Delete this file.
Open the solution back up.
Redeploy the program.
This did it for me.
Solution User Options file (.suo), this file stores user preference settings and is created automatically when Visual Studio saves a solution.
I use an extension called Live Server in Visual Studio Code. When I run live, the browser opens and the url is http://127.0.0.1:5500/index.html. Why can't I open this url on my phone's browser to see the live site on the phone. Is there a way to do this (Live reload on phone and browser)?
Note: I also develop using ionic and when I ionic serve I can see it on browser and when I open the ionic dev app (not ionic view!), I can see the live app on the phone. I can view it on multiple devices with the condition of all devices being in the same network which I am fine with.
127.0.0.1 is a special-purpose IPv4 address reserved for loopback purposes. That is, this IP refers to your computer itself.
By entering http://127.0.0.1:5500/index.html in your browser, you're requesting web page within your computer.
In normal case, your computer will be in a NAT network (under same wi-fi AP for instance), and you'll be assigned with a virtual IP. Normally it's 192.168.x.x.
You may enter the following command in your command prompt to see your IP address.
ipconfig
If you're using Mac or Linux, use this instead.
ifconfig
As a result, under your network interface card, you'll get your IP Address.
If the IP address belongs to virtual IP, then you may access it with your phone using
http://< Your IP Address >:5500/index.html
If it's not virtual IP, it is Public IP. Then, you'll have to configure appropriate Firewall settings under this circumstance.
Hope this will help.
You cannot open the same url on your phone, because that url host (127.0.0.1) refers to the localhost (the same machine).
If your phone and server are on the same network, you can replace the current host with the servers local IP.
So if your servers local IP is: 192.168.0.36
the URL you enter in your phone should be http://192.168.0.36:5500/index.html.
I had a same problem.
Solution: Control Panel -> Windows Defender Firewall -> Allow an app or feature through Windows Defender Firewall -> Allowed "code.exe" app.
Run ipconfig and find your private IP.
Make sure your phone is on the same network.
go to http://192.168.0.***:5500/
Open Live server's settings.json and add these two settings "liveServer.settings.useLocalIp": true and "liveServer.settings.host": "localhost". Then type your localhost ip in your mobile browser (in my case it was 192.168.0.110) with the rest of the Live server URL i.e. 192.168.0.110:5500/index.html. This worked for me.
Let me clear this out for you. we call localhost or 127.0.0.1 as loop backs. which will itself point to the same machine(means that particular service should also be hosted in the same machine). what Microsoft did with visual studio live share is that if have the live share extension it will create a reverse proxy between the host(where the server is hosted) and the target (In this case your browser) which means even though your host is in a different country the extension will tunnel the transparent proxy to your loop-back address. visual studio live share extension is what you phone doesn't have and Microsoft doesn't support yet. If you still want to access your local service what you can do is turn off the firewall(or pass through that particular port where ur service is hosted) and connect your phone to the same network as your machine with the service running and instead using http://127.0.0.1:5500/index.html use http:// UR SERVER IP :5500/index.html you can get UR SERVER IP by giving ipconfig in windows command prompt or ifconfig if ur server is on linux.
I am running easyphp with apache version 2.4.18 x86 (32-bit) on Windows 10.
On the PC where easyphp is running, I can connect using either localhost or http://computername, but if I try to connect through the local IP address which is http://192.168.0.10, I get a white page without any error message.
And the most strange thing, if I plug an iPhone (USB) with a shared connexion in the PC (the PC gets 2 network connections), then I can access to http://192.168.0.10 through the PC (still the wifi IP local address and not the iPhone local network address).
If I unplug the iPhone, then it fails again to connect to http://192.168.0.10.
Any explanation ?
So it was a firewall problem.
Evene when desactivating the firewall, the web site was not reachable.
I've added manually the
EasyPHP16\eds-binaries\httpserver\apache2418vc11x86x160927105506\bin\eds-httpserver.exe
in the Windows firewall rules, and it worked.
The two strange things is that disabling the firewall did not arrange anything, and lanching the webserver did not pop up the firewall dialog.
Hope this helps.
I am trying to connect XenCenter 6.0 to Server installed with XENSERVER 6.0 but i can't connect.
It give me error when i try to connect :
"Unable to connect to server '192.xxx.xxx.xxx'.
The connection was refused.
Check that Xenserver is configured correctly on '192.xxx.xxx.xxx'."
Also When i was using another computer for connecting xencenter, It was disconnecting automatically every time i connect
Examine some details:
List item
the server is power-on
the network configuration is right.(try to use "ping" or "ssh" to check)
the firewall setting
duplicate IP address which has been used
There are two possible scenarios in this case .
Either
1. The xenserver physical machine is powered off.
Or
2. The network cable is not connected properly.
If the server is pingable, make sure xapi and xapi-ssl are running.
ssh to the xen server and check the following:
/etc/init.d/xapi status
/etc/init.d/xapi-ssl status
If they are not running restart them
/etc/init.d/xapi start
/etc/init.d/xapi-ssl start
might require a xe-toolstack-restart
thank you for reading my question.
I want to login the virtual machine romotely through rdpweb shipped with virtualbox sdk.Of course, the virtual machine was installed in the virtualbox.The rdpweb(a folder) contains 4 files, webclient3.html, swfobject.js, webclient.js and RDPClientUI.swf.
Firstly, I copy rdpweb to the /.../tomcat/webapp. So i can visit webclinet3.html now. And there is a image which shows what i get.Sorry, i haven't enough reputation for posting a image.I just can put a link to the image.

An error happened. Google says that putting the crossdomin.xml to the root of webapp would solve the bug.The bug may be aroused by flash.But it is invalid for me. Why ?
My physical host is win7(ip:192.168.1.107), and my virtual guest is windowsxp(ip:192.168.1.111). The version of the virtualbox is 4.1.8.
Any help would be appreciated!Thank you very much.
I am so sorry for my poor english.
Update:
Your configuration looks like you have configured your WinXP guest with a bridged network adapter, and you are trying to connect directly to it. Have you enabled Remote Desktop on the WinXP guest? Go to the Control Panel -> System applet, then choose the remote tab and be sure to check both boxes to allow remote desktop connections. You will also need to make sure the firewall will allow this connection to the guest.
VirtualBox also have the capability to serve up a virtual machines display over RDP or VNC (VNC in the OSE - Open Source Edition). If you are wanting to use that capability then you should be connecting to the HOST IP address - not the guest. Since your host is Windows 7 you will also need to adjust the Remote Display Server Port for your guest (in the VM Settings in VirtualBox) to use a port besides 3389. I usually pick 3390. Your screenshot doesn't show somewhere you can enter the TCP port, so this approach may not be supported, but you could try appending :3390 to the IP address.
Original Answer:
Could you post the crossdomain.xml file you are currently using? This is almost certainly a problem with it.
My guess is that your crossdomain.xml file should look something like this:
<?xml version="1.0"?>
<!-- http://127.0.0.1:8080/crossdomain.xml -->
<cross-domain-policy>
<allow-access-from domain="192.168.1.111" />
</cross-domain-policy>
You could start with just putting * instead of the IP address in the file as well - though that is generally not recommended as it opens the possibility that the flash player can access any resource on any network. It would make it easier to access other virtual machines you might use in the future with different addresses.
