comment What's the difference between 127.0.0.1 and 0.0.0.0?
@whoKnows No: 127.x.y.z belongs to this computer for any x y z. "localhost" is just a name for 127.0.0.1, so forget "localhost". Use the -n or -d flag of netstat and related programs to show numerical addresses, not names. 127.0.0.1 is not the same IP adress as 127.16.23.42. So 127.0.0.1:80 and 127.16.23.42:80 represent distinct TCP endpoint addresses, a webserver at the one address cannot be found at the other address.

@whoKnows Of course. localhost is 127.0.0.1, not 127.16.23.42.

comment Does disabling IPv6 decrease my surface area of attack and increase performance?
"All of our internal IPv6-enabled networks were exposed to the internet." The real question here: why was this such a serious issue? I know people who have given up (I am not making this up, they told me explicitly they have given up) on knowing 1) what's installed 2) what's listening on a socket 3) what's a potential vulnerability, and I think it's terrible. Defense in depth in one thing, but you need to know which processes have listening sockets and potential vulns, or worms could spread from inside the border firewall (or NAT device).

comment How to disable SSL for some websites in Chrome?
"This would probably throw an error in the browser that it is loading over an insecure connection" You would have to install the certificate of your TLS proxy on your computer, as a trusted certificate.

comment Can I build a VPN on top of Tor?
"Take a look at NoScript." It is a very useful extension (and it has an HTTP sandboxing feature). "Not loading all the external JS also prevents most of the tracking cookies." Websites can still "track" you with other means. "Does not matter how you call it." Using the proper terms matters a lot.

comment Can I build a VPN on top of Tor?
"do not load all those tracking cookies and Facebook widgets without my explicit permission". That is not what "sandboxed" means. A sandbox is an isolation feature. JS loaded from one site cannot read content from other sites, or from local files: that's isolation. And a tracking cookie is just a cookie; the browser cannot tell a tracking cookie from another cookie. You can blacklist several domains known to send tracking cookies, but it is not an isolation feature.

JS is "sandboxed" by default.

comment Setup Tor/vidalia with vmware workstation
I think you need to change SocksListenAddress 127.0.0.1 to SocksListenAddress 192.168.x.y.

comment Setup Tor/vidalia with vmware workstation
Your config file does not look right... I think you first need to determine the correct local IP address (maybe not 192.168.23.1), and then put in place of 127.0.0.1.

"I tried to put it in torrc configuration from vidalia but it "doesn't recognize the action"." can you describe what you did exactly?

comment Must TCP use IP?
You might as well pretend that UDP is the same protocol as IP, because they offer extremely similar interfaces to upper layers: set a local and a remote endpoint addresses, send and receive packets...
