comment Best way to find out what Linux Version is used on a Webserver
The URL doesn't tell you anything about the O/S you are connecting to. The response headers may tell you what O/S is in use, or they may provide a complete falsehood if the administrator chooses.

comment Disable user shell for security reasons
Some email systems allow use of their own password mechanisms. I use Dovecot and Exim with an email only password. This allows use of webmail on servers I would not use my system password. Virtual email domains require their own password as they aren't coupled to the servers password system.

traceroute -T --port 22 would work also, but by default requires root access. tcptraceroute works without root access.

comment How do I find out if I am sudoer?
Your password for sudo is your login password. sudo will ask for your password to verify it is you checking. Passwords are usually remembered for a few minutes if you are few minutes.

@bev The <Directory /> could allow access but it is more secure for it to deny from all. The /var/www should match the directory specified as your site's DocumentRoot.

Most systems have at least a Time of Year (TOY) clock. While not as accurate as other sources, but usually relatively accurate. It should be fudged to a high stratum as shown so it is only used as a last resort.
