comment Why is connecting to a web server listening on an IPv6 link-local address unreliable / How is IPv6 neighbor discovery expected to work?
That's true, @mcr, resolving a mDNS/DNS-SD/zeroconf/Bonjour name to a link-local IP address works perfectly well.

comment Is it okay to copy an image file which is still mounted via a loop device?
@AquariusPower kill -SIGSTOP is different. It does stop a process from running, but it doesn't make the filesystem promise to write outstanding data to disk. kill -SIGSTOP of all processes that could potentially write to the affected filesystem plus running sync would come closer, but fsfreeze is both easier and offers a more robust guarantee.

comment Is it okay to copy an image file which is still mounted via a loop device?
@AquariusPower yes, you can use fsfreeze to temporarily lock the filesystem in a consistent state. Without a snapshot, you must wait until the copy is finished before you thaw the filesystem. With a snapshot, you can thaw as soon as the snapshot is taken. fsfreeze uses the same interface as LVM uses when it makes its snapshots.

comment DNSSEC - How many DS records are ordinary?
The DS records belong to the KSK key. The tools like dnssec-signzone that handle the generation for you automatically should also handle this automatically.

comment Custom timezone resets to default timezone in Centos 6
I didn't phrase it as an answer @jeremyclarke because it is a bit of a wild guess I was just hoping might be lucky. Based on the fact that you are saying that your system does not have a /etc/timezone the guess is probably a miss.

comment How to trigger custom actions in dovecot, when email is moved or deleted?
For a nice clean implementation of such a system, I think you are in "write your own plugin" territory. Unfortunately, after having written several custom Dovecot plugins, I can affirm that it's not that straightforward. However, your whole scheme seems like the germ of a good idea that can be expanded into a piece of software that many people would be interested in, so +1.

comment What's the difference between `dig` and `host` when querying a specific name-server?
dig can do both regular questions (all types except AXFR) and zone transfers (type AXFR) but DNS operators usually restrict zone transfers to authorized slaves so you most probably want to use regular questions

comment Setting up Outlook.com as mail server MX record trailing dot
To check the serial number, use dig @<nameserver> ***.org.il. soa. It should match between the primary and all secondaries. If your secondaries are configured correctly, they should get notified automatically when you increment the serial number on the primary and reload the zone.

comment Why does ipv6 not specify a protocol version?
Ah yes, I see I misunderstood what you were asking! But yeah, you seem to have got the answer you were looking for, regarding the next header field.
