I have following problem.
My operating system is Windows 8.1.
I have installed VirtualBox which registered new network adapter during installation.
After that TeamViewer works incorrectly. In the "Your ID" field I see two IP addresses of network adapters instead of generated id by TeamViewer.
Question: What should I change to make TeamViewer display again valid "Your ID" ?
I resolved the issue!
Something happened with TeamViewer settings, that is why "your id" field was displaying ip address. This happens when TeamViewer configured for LAN connections.
(Why TeamViewer settings were lost is still question for me :) )
To fix the issue, it is necessary to change network settings:
In TeamViewer open Extras -> Options, and in General category find Network settings and under
Incoming LAN connections, select the accept option.
TeamViewer shows the local IP address if it doesn't have a working internet connection. You can still connect to it over LAN per IP (must be activated in the options).
Click Settings button and deactivate incoming LAN Connection that worked for me

I have successfully built the client and server modules from the Getting Started with Winsock tutorial.
I have a desktop and a laptop both connected to my wireless router – both running Windows 10.
Running the client module on the laptop, I am able to successfully transmit data back-and-forth to the desktop (running the server module) using the desktop's IP address.
Running the client module on the desktop with the laptop's IP address as the command line argument, I get an "Unable to connect to server!" message after a ten second delay.
If I try to run both modules on the desktop in separate console windows using the "localhost" command line argument, the client console displays "Bytes sent: 14" and hangs waiting for a response from the server – however this works if I use either the desktop name or the desktop IP address in place of "localhost".
I am able to run both modules on the laptop using either "localhost", the laptop name, or the laptop IP address as arguments.
I have gone through the same motions with port 27015 forwarded on the router and incoming and outgoing firewall exceptions added to both the desktop and the laptop – there is no difference either way.
Any assistance would be greatly appreciated as I cannot figure out why this works in one direction but not the other.
Thank you for the suggestions Karsten and Andriy. I first tried getting the two computers to ping each other and neither was successful. After researching online, I was able to get them to ping after turning on "echo requests" in the firewall settings, but my original problem persisted. I then tried turning off both firewalls and I was able to get my server and client programs to work both ways. That wasn't a great long-term solution, so I tried selectively disabling the firewalls and realized it was an issue on the laptop's end. I noticed that my "server.exe" program was in the allowed apps list twice – one instance granting private access and one granting public access – but only one instance was active. I deleted both and added "server.exe" again with both public and private access boxes checked, which solved my issue.
I don't know what's wrong with it. Here is a screenshot.

Yosemite is my OS. Please help me,
Assuming that you have the right key file, you could be running into some security settings issues. Check your security group and make sure that the server is accepting connections on port 22 from all addresses. Also, I generally use the IP address when SSHing into an EC2 box instead of a url, as it is much shorter and more concise. Also, make sure that your server is running Ubuntu. I know that different OS's on EC2 use different default usernames.
Your default username can be found at this page:
http://alestic.com/2014/01/ec2-ssh-username
In the end, your ssh command should be something like
ssh -i otkey.pem [username for your os]#[ip of your box]
Hope this helps!
You've got the right command for an ubuntu server. Check to make sure that security groups are configured and that you don't have Network Access Control Lists configured on your VPC. The configuration you made to the settings of your laptop are to open it up for people to log into your laptop, they don't do anything to facilitate you connecting out.
I'm developing an application in C++ for Windows 7, that sets up a TFTP server to communicate to an embedded device. The device is supposed to be connected directly to the Ethernet port, and it expects a TFTP server on 192.168.1.19 static address.
To simplify user experience, I want the following scenario:
present a list of all network connections registered in the system to the user (same list as in "Control Panel\Network and Internet\Network Connections")
allow to choose one connection
memorize its IPv4 configuration
set IPv4 configuration to 192.168.1.19 and 255.255.255.0
after TFTP job done, restore original IPv4 configuration
The problem I encountered is a mix of the following:
when no Ethernet cable plugged, neither of GetAdaptersInfo, GetInterfaceInfo, GetAdaptersAddresses list the connection I'm interested in;
even if I get that connection, I'm not sure which API to use to set DHCP on/off, static IP, network mask.
I tried using netsh, and it works fine, but I don't want to run it from my app, because I don't want to deal with non-English characters in the connection names.
Suggestions welcome,
Thanks!

Tried WMI query "Select * From Win32_NetworkAdapter Where NetConnectionID = 'Local Area Connection'" -- no IP address in the feedback, although I can see it in the Control Panel connection properties.
Queries involving Win32_NetworkConnection don't return anything at all.
I ended up using:
"Select * From Win32_NetworkAdapter Where PhysicalAdapter='True' AND AdapterTypeID=0" query to list adapters/connection names/guid - works pretty good
registry to read configuration via guid
netsh to do configuration via connection name. Yes, I had much fun with locales.
I frankly didn't find a more reliable way to work with disconnected connections. Hope this helps. If anyone has better solutions - I'd be glad to see them!
This might seem like a duplicate question but it is not. I tried to go through similar questions but I couldn't find a fix for my problem. Here is my problem:
I need to set up an ftp connection on company servers.
I can easily connect to ftp server from fileZilla on my PC but when I try it over one of the server machines to the file server all I see is the following:
Response: fzSftp started
Command: open "*****#***.***.***.**" **
Error: Connection timed out
Error: Could not connect to server
Status: Waiting to retry...
Status: Connecting to ***.***.***.**...
Response: fzSftp started
Command: open "*****#***.***.***.**" **
Error: Connection timed out
Error: Could not connect to server
I googled the "Connection timed out"
error and I realized that the first place to check is firewall or router setting. these are outsourced to another company and they say that the issue is solved and it should work fine. I don't know where to look at.
I've had lots of issues with Filezilla. You may try another software first to see if Filezilla itself is the issue.
If you're on Windows, I highly suggest the open source project WinSCP (https://winscp.net/eng/download.php). For Mac, Cyberduck (https://cyberduck.io/?l=en) is solid (and free), though you may prefer Transmit.
I was having this problem after upgrading Filezilla. I downgraded it to a previous version and it worked like charm. I came across this ticket thread and it was absolutely helpful : Filezilla Support Ticket
Check your security group rules. You need a security group rule that allows inbound traffic from your public IP address(Google: What is my ip?) on the proper port.
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
In the navigation pane, choose Instances, and then select your instance.
In the Description tab, next to Security groups, choose view rules to display the list of rules that are in effect.
For Linux instances: Verify that there is a rule that allows traffic from your computer(public ip) to port 22 (SSH).
For Windows instances: Verify that there is a rule that allows traffic from your computer(public ip) to port 3389 (RDP).

I need to set up an ftp connection on company servers. I can easily connect to ftp server from fileZilla on my PC but when I try it over one of the server machines to the file server all I see is the following:
<failure to connect code>
Please note that public IP and internel IPs will be a different address; such as 123.456.675.574 for the public but internal to the server network it will be something more like 192.168.10.574 .
This is why you can easily connect from your PC because it uses the public IP address but from the internal IP network of the company servers that address will not be valid, and the internal one would need to be used instead.
Try this, 200 is just an example, just increase it and try.

I want to access Internet from my BB10 simulator.
I have changed the setting of the virtual machine and changed the Network Connection type from NAT to Bridged.
But after this when I restarted the simulator, it is unable to get the IP address. Thus QNX IDE is unable to discover it.
Please suggest how can I resolve this issue ?
According to an administrator on the blackberry forums you can do the following:
http://supportforums.blackberry.com/t5/Cascades-Development/BB10-Dev-Alpha-Simulator-not-connecting-to-WiFi/td-p/1842579
1) Power down your VM
2) In VMWare select your VM and then click "Edit Virtual Machine Settings"
3) Select Network Adapter
4) Change from NAT to Bridge mode, which will allow the simulator to have direct access your physical network card.
5) Start the simulator again.
In case this is still an issue for you or anyone else; If I understand correctly, when you switch to bridged connection, you do have internet access on your simulator, but the QNX IDE does not find it via device discovery.
I just had the same problem, it can be solved by typing the simulator IP in by hand. Note that you have to use the address that VMWare displays at the very bottom of the content window, not the IP that is set in Development Settings.
I suspect the QNX IDE of only scanning a certain IP range for target devices. Thus, when you switch to bridged mode and your device obtains an arbitrary address in your LAN, it does not (necessarily) fall in that range.
