comment OpenVPN: unable to reach clients over IPv6
So if you look at your route table you will notice that there is no route for 2001:1af8:3100:a00a:0021:a:b:0000/112. Either OpenVPN is not configured to add it, or it is refusing it to add it because you already have 2001:1af8:3100:a00a::/64 locally configured. See your OpenVPN log files. Bump up the log verbosity to 4 will probably give you more info as well.

comment OpenVPN: unable to reach clients over IPv6
Sigh, this is going to sound condescending, but if you have if you have a problem with getting packets from one place to another then you have a routing problem. And when you have a routing problem you should include route tables, and traceroute. Also why a /112? I suspect OpenVPN will support it, but you really should give your VPN a full /64.

comment how to rename multiple files by replacing string in file name? this string contains a “#”
Sure, as you would have seen from the documentation you surely reviewed, the -n is the no act option. Which lets you see if it works before you actually use it. Did the output on the screen show the potential new names correctly?

comment Multiple MX records pointing to multiple servers for a single domain
The specifics can be pretty complex, and heavily depend on what MTAs you are using. Some MTAs simply wouldn't be able to support a setup like this. Some can do it easily.

So what have you actually tried? I see that you have linked to a few questions and say they failed, but how did they fail? IMO the best example uses the rename command. I suspect your rename would be as simple as rename -n 's/#/safeNBC/' *.jpg.

Try changing your AuthzLDAPUserKey to sAMAccountName.

comment Why does Hyper V differs in authentication methods for live-migration and replication
I believe replication can be used across domains. Live migration is within the domain only. But I am not certain.

What ldap server? Is this AD, or something else?

comment Architecting for Load Testing
This might be a case where the 'cloud' might give you what you need. Want to load test? Spin up a new instance identical to your prod instance for a few days.

comment Understanding SAS transfer speeds
Where did you get your numbers from? I thought 12Gb/s was supposed to be good for 9,600MB/s, not 4,800MB/s which is the rate for 6Gb/s SAS. Ref. I am not sure how 12Gb/s relates to the 9,600MB/s value though.

comment SSH tunneling is faster than OpenVPN, could it be?
Sure there might be a little more overhead with OpenVPN because it has the extra IP/TCp headers. But that shouldn't make a difference of 4-10 times slower. If the difference was in the 5-10% slower range I might be tempted to blame that. The reason you might want to still investigate is that this could be a symptom of some underlying problem that might be impacting other things in a way that is less obvious.

Do you have any kind of teaming/link aggregation setup on that server?

Create lots of stateless rules, like we did back in the ol' ipchains days.

comment “Cannot open SSH Tunnel” on MySQL
getaddrinfo failed - That points to a Name resolution problem. Can you verify that nslookup is able to resolve the name.

comment SSH tunneling is faster than OpenVPN, could it be?
Wow your test results comparing SSH and OpenVPN give results I would not expect at all. If you are interested in digging deeper I would use a different tool to test instead of redis. So I would try running iperf tests over your ssh/openvpn tunnels, and get the bandwidth latency results. Past that, I would probably fire up tcpdump and see if there is anything happening while you are using OpenVPN. Lots of retransmits, unusual fragments, any errors, etc.

comment SSH login works but SFTP login doesn't
I would be tempted to fire up tcpdump on the VPS and see if you can actually see the incoming sftp connection. Something like tcpdump -qni any port 22. Though you might have to add more filtering to exclude any active SSH connections.

comment Order of resource/class execution in puppet manifest file
Puppet will apply the changes in a seemingly random order. - Of course if you have new enough version of puppet you can use ordering = manifest. Explicitly stating relationships, like you suggested, is strongly prefered to make your manifests more readable.
