I all of sudden noticed that my hard disk is having a lot of activity, and I closed all my applications.
My VMWare box stopped working too. I'm concerned that someone accessed through my pc.
Therefore I'm going to monitor activity through iostat. Please install it first by doing the following:
sudo apt-get install iotop
sudo iotop --only
I can see that only myself is connected and root doing activities in background. Coincidently, s more responsive, but I can see that there are still activities running on behalf of vmware, where I already kill this window.
Doing a:
sudo ps -ef | grep vwmare
I can see several tasks running on behalf this application, but they are just ports opened.
I restarted everything again, and it seems to be working now. I'll keep monitoring.
