I'm a unix sysadmin, working as a consultant at Init AB (www.init.se).

Previous jobs include sysadmin in charge of security related systems at a large bank, and mail servers at a largish ISP, including handling abuse and spam issues.

comment How come the machine name shows up in the email header?
RFC5321: As discussed in Section 6.4, a relay SMTP has no need to inspect or act upon the header section or body of the message data and MUST NOT do so except to add its own "Received:" header field

comment How come the machine name shows up in the email header?
Gmail has internal logs giving them the ability to trace messages while munging the headers. And it still causes problems for other sysadmins when their users misbehave. Munging information like that breaks the RFCs and should be discouraged. (Speaking as a sysadmin who started managing email nearly 20 years ago...)

Why should it strip out information that can be used to e.g. find spammers, figure out deliverability problems or otherwise be of use to sysadmins?

comment OS X not resolving hostnames for SSH/HTTP
Check serverfault.com/questions/578952/… - it may be the same issue, that the Mac tries IPv6 which isn't resolvable.

comment Convincingly “breaking” a system for a non technical user
I've used it at work, when people have failed to lock their computers. They have then generally kept programs running, too, and of course the desktop image of those programs don't accept input. Usually I've only needed to do this once per user in order to make them learn to lock their computers.

comment Multiple web servers behind one public IP
Set up an apache server with mod_proxy and proxy each of the sites to its own server. THe router need only do port forward to that one apache server.

comment Was this a DoS, a hack attempt, or something else?
It's a crack attempt. As @MichaelHampton says, welcome to the Internet - this will keep happening.

It depends on how the script that does the restart is written.

Or use stunnel (stunnel.org), which will setup an encrypted session without requiring a shell login.
