comment Do search engines give searcher's IP address to sites that come up in search?
@tim - if the site owner uses google analytics, you get the searched keywords from looking at the analytics. (You won't get them for each individual user straight from google; but if you say cross reference info from the time, user agent, etc with keyword searches you can match them up in your logs.

comment Would the authorities in my college be able to see what websites I accessed through tunneling(SSH)?
ssh -D supports both SOCKS4/SOCKS5 (and man ssh explicitly says it supports SOCKS4 & 5 under the -D option in OpenSSH v6.2 or v6.6). SOCKS5 support has been in OpenSSH since version 3.7 (released Sept 2003). You still have to make sure that you are using SOCKS5 not SOCKS4 (when you configure your browser to connect to the proxy), and that DNS is being done through the tunnel, e.g., in firefox you'll have to enable network.proxy.socks_remote_dns in about:config.

comment Why for some SSL websites browsers show extra info, while for others dont
The benefit of EV certificates is they do fact checking. So if an attacker manages to get a domain like thepaypal.website, the attacker could get regular class-1 SSL certificates for it, but not EV ones as they would not be able to prove they are legal identity paypal.

-1 - This is wrong. Self-signed certificates will present a scary dialog "Don't trust this connection". The no green box is for regular CA signed class-1 certificates. This validates that the owner of the certificate also controls the domain. (E.g., you bought example.com and can receive emails at admin@example.com). The certificates with the large green boxes are the extended validation certificates which verify that a domain belongs to a real life organization (and the green box displays what organization).

comment Is Certificate-Based Authentication Really Better Than Password Authentication in OpenSSH?
@user10008 - My mistake. I thought "or better" was responding to DigitalChris not to TomLeek. My bad.

comment Is Certificate-Based Authentication Really Better Than Password Authentication in OpenSSH?
@user10008 - Disabling password entry in /etc/shadow is probably not desirable, as typically you may want the ability login to the machine via password when you are physically present (without requiring any of the standard tricks like booting into single user mode or mounting the hard drive from a live cd/usb and editing /etc/shadow ). You would also have to replace the password entry for every user to have the equivalent to PasswordAuthentication no.
