So, I read the manual three times, installed the Oracle service pack two times, tried to access five different virtual machines dozens of times with all kinds of authentications, followed every thread on this forum, all to no avail. I really did everything there is to do to my knowledge. But accessing Virtualbox regardless of the OS does not work in version 4.1.23. Two things seem just really bad:
The manual tells at no point WHERE on OSX the VBoxManager commandline tool is installed. But the manual references it dozens of times. It's on no search path in none of the shells I am using. Doing a find / -name "VBoxManager" as root reveals there is no such tool anywhere. Please, can someone let me know what to do to actually be able to do what the manual says with regard to the command line? Where does one get that tool?
I still would like to learn how one accesses a virtualbox installation with a remote screen. Here is what I tried;
as clients:
Apple Remote Desktop
Fails to find server
Apple VNC protocol from Finder
Fails to find server
VNCViewer (even though that is as unlikely to work for RDP as option 2)
Fails to find server
Microsoft Remotedesktop (that should work).
Fails to authenticate, after hitting the connect button one gets instantly the response that authentication failed, regardless of
means of authentication, such as NULL, External
Network interface (bridged, NAT)
IP address (the one the virtual machine obtains, localhost, my own host's ip address)
Port (tried different ports none of which were occupied)
Virtual OS (Windows 7, Windows XP, CentOS 6.3, ClearOS, backtrack 5)
Please, can someone help?

I have a whitebox dual CPU home server running ESXi 5.5.
I have loaded the server up with a bunch of VM's for learning Microsoft SCCM. I noticed that as soon as one of the guests gets under load, the host will crash with the attached photo (apologies for the quality). Could this be due to a dying CPU? I have noticed that one of the CPU's runs quite a bit hotter than the other.
Usually with CPU overheating the machine would shut down first, however if the temperature inside the case is too hot, something else might be getting affected (e..g memory or video display circuitry).
If you want to diagnose overheating, I can suggest placing a vacuum cleaner hose over the air vent, this will draw much more air than your regular fans. If the system stays up under load with the vacuum cleaner attached, it will be an overheating problem.
Not a programming issue, so I'll close this off and note the resolution I found incase anyone else has the same issue.
Looks like this was a known issue under ESXi 5.X that has to do with the E1000 and E1000e virtual network adapter as per the lines:
#BlueScreen: #PF Exception 14 in world wwww:WorldName IP 0xnnnnnnnn addr 0x0

Simply remove any adapters using E1000/e and replace with VMXNET3.

I'm looking to create a mobile app on IOS devices before I started I just needed to check up on one thing. How can I detect other IOS mobile devices within local rage e.g same room, same train, etc..
I want to be able to do it while the phone is locked, so bluetooth wouldn't be a great example as most people have it turned off.
Thanks!
The application has to send its location to the server.
Then the server knows where every devices that shared its location are.
Then your application can ask "who is around?" to your server... and your server calculates (let's suppose within a radius of 2 miles) who is around... and sends back to you.
It doesn't have anything to do with bluetooth. It's done via regular internet.
For other users of your app who want to be discovered you could use Bluetooth LE and the new iBeacon support added in iOS 7. Each user would have to launch your app and give it permission to start "advertising" their presence. However, the range of Bluetooth LE is like 10-20 meters (I forget the exact figure) and that will go down in "RF hostile" environments.
If everybody's connected to the same WiFi network you could use Bonjour.
Another option, as suggested by Wagner, above, is to have the devices send their locations to a central server.
I have a Kubuntu 12.10 64bit as host and CentOS 6 32bit as guest system on VMware player 5 on a Dell Latitude E6510.
Despite the installation of VMware tools, the clipboard exchange is not working.
I use a very similar guest system within VirtualBox and there cliboard exchange works fine.
Has someone experienced the same with a configuration similar to mine?
And is it possible, that the guest system causes the problem instead of the player?
I've found thaht suspending and then re-playing the VM will re-enable clipboard exchange.
Clipboard exchange will then work both between VMs and the Host machine as well as between VMs themselves.
(VMWare Player 5.0, Windows 7)
After having installed several constellations like that, I experienced, that in general it works, I can exchange the clipboard in both ways and even the desktop size adapts to the size of the VM window, but still from time to time having a situation, where it doesn't work and also heard of many other people who experienced that.
So, if someone can enlighten me on that point, I'll be happy, but I'm closing my question hereby.

I know, that this question was created many times, but it is stil open
The problem is following:
My application need to generate some UID for computer, it working on.
I need it to implement the genuine protection.
MAC address is a good candidate, because it is unique for each ethernet card.
Many articles uses either GetAdaptersInfo, WMI, NetBIOS or Sockets.
Here is one of them: Three ways to get your MAC address.
They, shore, return a MAC address, but this address can be set by hands from adapter properties
Control Panel > Network and Internet > Network and Sharing Center > Change Adatper Settings > right click on adapter > Properties > click "configure" button > go to "Advanced" tab > chose "Network Address" and change it
The all mentioned methods are not match my needs, because a MAC address, being set with driver has greater priority, than true hardware MAC address. This "fake" address will be returned by all Win API functions, that i know, and therefore, the genuine protection can easy be broken.
Any help from you, guys, will be greatly appreciated.
Thanks.
The only means that Windows has to access the MAC address is asking the driver.
That's what the driver is for - to talk to the hardware so that Windows doesn't have to include code for every single device anyone might come up with ever.
If the driver is telling Windows that the MAC address is something, then that's what the MAC address is.
MAC address is a good candidate,
because it is unique for each ethernet
card.
I'm afraid not. Firstly, I've read reports of customers receiving entire batches of machines with identical MAC addresses (apparently this causes pain when building clusters).
I have also seen with my own eyes a machine that changes its MAC address on reboot. Every time. It was an old IBM Thinkpad running Windows XP.
My advice: stay well away from MAC addresses if you're generating unique IDs.
I don't think "Network Address" you mention refers to the MAC address. Some devices allow you to "spoof" the MAC address for ISP purposes, but you should be able to get the real MAC using the methods you found.

I need something a little more feature rich than Sysinternals TCPView (which I regularly use) ... but it also must be freeware. :)
Well, the question is a bit old and I realize that probably you already found the software you were looking for... just in case, an interesting connection monitor utility is CurrPorts, by Nir Sofer.
Freely adapted from the program's home page:
displays the list of all currently opened TCP/IP and UDP ports on your local computer;
for each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it;
allows you to close unwanted TCP connections, and kill the process that opened the ports;
allows custom filters for inclusion/exclusion of connections.
Maybe a full blown traffic sniffer like Wireshark will complement your tool set?
Amongst wiresharks features are:
packet analysis
traffic statistics
capture
coloring
data export
I recommend TCPView for Windows v2.53.
image http://i.technet.microsoft.com/bb897437.TcpView(en-us,MSDN.10).gif
TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.
Not sure what features you are looking for so this is my suggestion.
Without having used it, I have seen TCPStat advertised a few times.
It looks like it was a discontinued project somewhere around 2003 and it's an awful blue color.
There's the MS Network Monitor.
Process Hacker shows also send/receive bytes, speed, country flag etc.
