Answer 1

1) Make sure the ssh connection is started with -X or -Y option. Example: ssh -X usernme@ipaddress

2) Restart the ssh connection, that is just exit and log in again!

Answer 2

Make sure you've added an host-only network adapter and connected it to the VM.

In order to so this on Virtual Box:

1. Open the VirtualBox preferences menu by clicking on File → Preferences

2. Click on Network

3. Click on the tab Host-only Network

4. Click on Add (the small green “plus” icon on the right side of the window)

An adapter called vboxnet0 will be created. The default settings should be acceptable

Then, from the VM settings assign the adapter to the Macine:

1. Click on the VM

2. Click on Settings

3. Click on Network

4. Change Network Adapter to be attached to "Host-only Adapter"

   • You can also use Adapter 2 and leave Adapter 1 connected by NAT to the Internet

5. Make sure the adapter you've just added is selected

Only then, you'll be able to connect to the VM with ssh -X usernme@ipaddress as @shr wrote.

If you ran info more issues, please read the setup notes

Answer 3

I got the same error like the ones mentioned in the question.

In my fix(after you ssh -X usernme@ipaddress), I changed to directory mininet/util and ran the shell script install.sh. So basically

1. cd mininet/util.
2. sh install.sh.
3. "sudo wireshark &". to start wireshark and you will get warning, just hit Ok

对于你想要观察的每个主机（比方说h1）：在mininet上： xterm h1在xterm h1 xterm上尝试： wireshark-gtk而不是wireshark
