Re: application for an employment

Using a web server is NOT a port scan - in any manner.

A portscan makes a connect(), a web browser makes a connect(). Please
explain where exactly you see the difference. Especially on layer 4.

Generally a port scan does not consist of connection to a single port on a
single host. Sending a mail message is TCP 25. I connect. 1 Port. Using a
web browser is TCP 80 (or other in some instances) 1 port 1 connect.

Next a port scanner opens a port and does not complete the session. It opens
and completes the TCP handshake (full scan - half scans, SYN etc even less).
A mail client connects to the SMTP server and sends a message (eg EHLO...
HELO etc)

Connecting to a range of ports and closing the connection is nothing like
sending and email nor using a browser.

A web client connects and send a request (eg GET / ...)

*public* internet addressing does not mean *public access*

Of course it does mean exactly that, unless authentication of some sort is
required.

Wrong sorry. An airport lounge is generally considered public, but the
airline who owns it still has the legal rights (as property owner -, inc
leasing) to restrict access and control what you are allowed to do.
