comment How to set the order of ipv6?
Good point. IIRC there is also the secondary flag if you want an address to be excluded here.

comment How to set the order of ipv6?
Linux uses longest common prefix to determine source address in the absence of a source address hint in the routing table.

comment SATA 7.2K HD Suitable for File Server
@PeterHorvath, my main gripe is that even if I extract a list of damaged blocks, I still have to do manual work looking up the files and finding their replacements. Comparing several TB of data against backups is not a viable option in my opinion. An extra disk costs less than the time of the admin cleaning up a bad block.

comment SATA 7.2K HD Suitable for File Server
@PeterHorvath, I'm afraid it's not. The main difficulty isn't in getting the RAID set back up and running, but also identifying what data was lost in the process. Only integrated solutions like ZFS have an automated process to map the failure to a specific file.

comment SATA 7.2K HD Suitable for File Server
Let me put more emphasis on the bit about having more redundancy. RAID5 and RAID1 with only two disks will fail in the most spectacular fashion if one disk is out and another disk has a single faulty sector. Obligatory anecdata: a friend of mine works for a data recovery company, and 90% of the work they get are RAID5 sets.

comment There is nohup, is there a nousr1 command?
The main functionality of nohup, by the way, is to disassociate the process from the terminal so it isn't sent SIGHUP in the first place. That it also sets up a signal handler is an additional bonus, but should be unnecessary.

comment Should I exclude all 'dev/' or only 'dev/pts/' during full server tar backup?
Note that udev is Linux specific. On other unixoid systems with a static /dev, it is indeed advisable to include it in the backup, and only exclude /dev/pts, which is dynamically managed even there.

comment How do I edit the SSH “last login” message?
The "last login" message is user specific, while the motd is system-wide. I'm not sure how you want to recreate the message. Also, there are people who actually read this message, and want it to be as accurate as possible.

comment Why is ARIN (etc.) allocating such large blocks of IPv6 addresses?
Also, using stateless autoconfig and security extensions, you get a fairly spread out use of address space, so it is no longer economic to scan for machines on the Internet, which is a large attack vector for worms.

comment A domain I've never heard of resolves to my website
The error is transient. It means that the grace period for rebinding the socket (120 seconds IIRC) has not yet elapsed. For config changes, reload is usually sufficient.

Your VirtualHost should have a ServerName -- that is the warning.

comment SNMP tick counter wrap around logic
You can detect a wrap easily (counter decreases) and correct by adding MAX+1 -- however if the counter was reset because the agent was reset, this would look like a wrap, so you don't correct if the sysUptime.0 also decreased.

comment Do wifi packets go directly node to node?
Both modes are allowed, unless the AP explicitly forbade. The stations decide which next-hop address to use.
