TeamViewer and remote access problem

Question

I install TeamViewer 8 on my Ubuntu 12.10 (64-bit) laptop.

I can remotely connect to my Windows 7 PC (32-bit), but when I try to connect from my Windows 7 device to my Ubuntu device, it works once perfectly, but if I try it again, it stops working.

How can I fix that?

Situation now: "FROM -> TO"

Ubuntu -> Windows 7 -> Working

Windows 7 -> Ubuntu -> Not working. Constantly says, "Connecting..."

I can send messages from Windows 7 to Ubuntu, but I can't connect.

I connected from my account on TeamViewer 8 and I have devices added to my account.

Solution

This could be caused by something using port 80 on the Ubuntu host.

You can use the netstat command to check whether or not something is using Port 80:

Run this command: sudo netstat -anltp|grep :80

You'll get an output similar to this:

What you're looking for is the IP address on the left (for me, 192.168.10.79) to end in :80 rather than :34567 for example.

If you see an application that is using 80 (skype and apache2 are likely culprits), you can kill them by using killall skype or similar.

From your question it actually sounds like the TeamViewer connection that you used prior is still "stuck open" somehow, so just do the same to TeamViewer (kill it if it's open, then retry).
