We had an issue recently where an application was not properly getting disconnected from SQL during a failover of an AlwaysOn Availability Group (AOAG). Some background: The application was accessing the primary node, and after the failover the application continued to access the same node. Unfortunately, as it was now read-only, the app was not very happy.
Turns out it was due to the Read-Only configuration of the secondary. We had it set to “Yes” which allows any connections to continue to access the secondary with the assumption the application is smart enough to know it can only read. It appears while using this setting, connections aren’t forcefully closed, causing all sorts of issue.
Setting it to either “No” or “Read-Intent Only” properly severed the connections for us. Yay!
For more info.
Looking to update your Azure ILB endpoints, but are struggling with the Set-AzureEndpoint cmdlet? You should be using the Set-AzureLoadBalancedEndpoint cmdlet instead!
One of the bigger things I see as a complaint about the Surface Pro 3 (SP3) is that by default the Function keys are not the primary button press. Instead the defaults are the shortcut keys. Additionally, it’s not really documented anywhere how to switch what is primary.
Well, you can. Just use CAPS + Fn to switch between what you want to be primary.
Unfortunately, I use a lot of the Fn keys, but also Home and End. Oh well, guess I can’t have my cake and eat it too.
Another one of the great things about using a Synology is having access to all the great packages that both Synology and the community create. You find out about so many different apps you may not have been familiar with. Turns out Bliss was one of those (grab the app from Patters).
I have a fairly large music library I’ve composed over the years, and while I was picky about folder structure, all the other stuff was lacking: tags, images, etc. Back in July of 2012 I gave it a first run and liked what it did. However, I didn’t keep it installed (didn’t think I would need it continually).
Fast forward to last week, and I reinstalled it to help clean things up again – I had to restore lots of my music which meant the tags, folder structure, etc. were all messed up again. I’m loving it all over again for it’s ease of use and continual running in the background.
Turns out in the current release they’ve added some new case rules which I love, but was having a few issues with it. Shot of an email with some of the details, and got an immediate response saying it was being fixed in the next release that was in beta. I asked if they wanted any help with testing, and sure enough Dan (creator) gave me links to the beta which I promptly installed (replaced the bliss-bundle folder after you extract the Linux jar file).
Can’t say enough about the customer service, plus it’s fixing all my music issues in the background. Yay!
One of the challenges with running my own server now, is making sure everything is properly patched. With the big stink around the new Heartbleed vulnerability, it made me look into it a bit.
Turns out, in order to fix you can run the following:
sudo apt-get update
sudo apt-get install -y libssl1.0.0 openssl
# Confirm Build Date is at least Aril 7th 2014
openssl version -a
# Restart all services listed by this command:
sudo lsof -n | grep ssl | grep DEL
With the move of my domains to Azure instead of Dreamhost (oh, did I not mention that?), one of the things I needed to do was setup some SPF records to keep email from going into junk folders.
Now, there is a great article on creating SPF records, but those that know me know I’m not a big reader when there is a lot of text. Pictures FTW!
Anyways, as MS is a big proponent of utilizing SPF, they have created an excellent tool to create the record’s text. Yay team!
I’ve finally migrated my email from google apps to outlook.com. The key item that caused some issues was using domains.live.com. I had added the MX record that proved I owned it (and email was flowing correctly).
However, it was always set to “pending” and never switched to “active”. The problem is that the Hotmail.com MX record is the only MX record you can have. I had some of the old gmail records listed still, but at a much lower priority (higher number). Removing them immediately made it switch to active.
In the last few releases, Synology has added L2TP/IPSec as an option for a VPN. I’ve never been able to get it to work on a Windows client until today.
- IPSec – UPD 500
- IPSec NAT Traversal – UDP 4500
- L2TP – UDP 1701
Fix on Windows clients – http://support.microsoft.com/kb/926179
- For Win7 and Win8 Machines
- New DWORD (32-bit) – AssumeUDPEncapsulationContextOnSendRule
- Set the Value Data to 2
Using OpenVPN with port 443, for easier access: http://forum.synology.com/enu/viewtopic.php?t=45545#p215354
I finally got around to installing Windows 8.1 Public Preview. I am definitely liking the new digs. However, I already started to look into how to uninstall due to the following items that I’ve now gotten sorted out (hopefully helps someone else):
- I couldn’t connect to any of my local network resources: iSCSI targets, NAS shares, NAS website. However, I could ping them and SSH just fine. I thought it was something to do with the iSCSI targets because whenever I tried to enable/disable task manager showed 5MB+ sustained traffic flowing over the network. Obviously not a good thing. Well, it turns out it was the “Microsoft LLDP Protocol Driver” on the network connection. The picture below is what I unchecked to make everything start working again including being able to restart the machine. And yes, while this is a Hyper-V virtual adapter, similar problems were happening when I wasn’t using Hyper-V (trust me, I tried everything!).
- Windows + S no longer works for OneNote screen clipping!!!!11one I get that it makes sense for it to go to Search now, but dammit Microsoft, stop messing with my shortcuts! First it was Windows + Q moving from lync to search (which also brings up search in 8.1 Preview), and now Windows + S is taken from me too! Grrr
Oh well, with the bad comes the good:
- Love the desktop wallpaper being in metro
- Love the auto-complete for when I launch an app
- Love the minimalistic Start button
- I am enjoying IE 11, but we’ll see how long that lasts
- One I get the RT tab updated, the labelling of groups will be nice
Overall, seems to be good now that I’ve surpassed the biggest hurdle.
