networking - AD Dynamic DNS not working with Linux IPv6

I have an AD DNS/DHCP enabled server. I have mixed Windows and Linux machines/servers. IPv4 is working great with DNS/DHCP, even for the Linux systems. IPv6 is working great except that it won't generate a DHCP lease or DNS entry. If static IPv6 AAAA records are used, I can use my RAS server, browse IPv6 websites, and connect to any machine, even across the internet.

What I can do with IPv6: I can get a DHCP IP address on any system, Linux or Windows. I have fd0a:fb5*:bdc*:0::x as my /64 prefix and it works great; ALL systems have an address with this prefix. can ping, DNS lookup, and connect to Windows systems and websites perfectly. The only issue I have is that IPv6 leases and DNS AAAA records are not added/updated dynamically for the Linux systems. A records and IPv4 leases all work fine.

I have added a dedicated user called DHCPDynUpd and given added it to the DNSUpdateProxy group. I then assigned a password that never expires and denied logon hours and disallowed signing into any machine. In the DHCP settings on IPv4 and IPv6 I signed that user into the DNS dynamic update registration. Then I set the IPv4 settings to "Dynamically update DNS A and PTR records for DHCP clients that do not request updates (for example, clients running Windows NT 4.0)"; this is not a setting under IPv6. Then I set them to both dynamically update A/AAAA and PTR records.

I know the user is working or the DDNS updates for IPv4 wouldn't work...

Also on the Linux machines I ensured that they are set to a FQDN in the hostname file and that they are broadcasting the hostname/domain in the dhclient config.

Machines used:
⠀Windows Server 2012R1,
⠀Fedora 20 VPN/mail/web servers,
⠀Windows 8.1

Some resources I found and followed to the best of my ability:

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
