Recently, I bought a Asus RT-AC51U for Android USB tethering and 5GHz features. I also bough some new wireless USB device. Two D-Link DWA-171 A1 are for Mac mini and NAS. One D-Link DWA-131 E1 is for Lenovo C440.

Because DWA-171 A1 is compatible with OSX, Windows Server 2012 R2, and QTS but DWA-131 E1 isn’t for QTS, I decide to test wireless transfer between Mac mini and two NAS.

Asus RT-AC51U

WikiDevi is a good source to know more about your router. But the internal search tool is always missing, I suggest to use Google with site:wikidevi.com to search within WikiDevi or just edit URL directly.

According to ASUS RT-AC51U on WikiDevi, here are some important features:

Because it has 2×2:2 2.4GHz antennas, 802.11n at 2.4GHz is up to 300Mbps.
Because it has 1×1:1 5GHz antenna, 802.11n at 5GHz is up to 150Mbps while 802.11ac is 433Mbps.
802.11n at 2.4GHz is handled by MediaTek MT7620.
802.11n at 5GHz and 802.11ac are handled by MediaTek MT7610E

About 2×2:2, the first number means there are 2 antennas for transmitters (TX), the second is 2 antennas for receivers (RX), and the last number is up to 2 spatial streaming. A more detail explanation may be found in 802.11n on The Cisco Learning Network and 無線網路新趨勢–漫談 802.11ac 新協定 on NTU.

D-Link DWA-171 Rev A1

The H/W ver: A1 is very important information but only show on a small label on the package or the last few characters of P/N on the device. Different hardware version might use different chips result in different performance and comparability.

According to D-Link DWA-171 rev A1 on WikiDevi, here is an important feature:

Realtel RTL8811AU supports draft 802.11ac which is not 802.11ac.
Max speed for 802.11n is 150Mbps with 1T1R.

It works on OSX, Windows Server 2012 R2 and QTS.

D-Link DWA-131 Rev E1

The H/W ver: E1 is very important information but only show on a small label on the package or the last few characters of P/N on the device. Different hardware version might use different chips and result in different performance and comparability.

According to D-Link DWA-131 rev E1 on WikiDevi, here is an some important feature:

Realtel RTL8192EU supports 802.11n.
Max speed for 802.11n is 300Mbps with 2T2R.

It works on OSX and Windows Server 2012 R2.

Thecus W5000 with Windows Storage Server 2012 R2 Essential

W5000 use a Intel Atom Processor D2550 which is a 1.86GHz dual-core processor with Hyper-Threading Technology. It has 1MB L2 cache, Intel 64 Architecture, and supports up to 4GB DDR3.

The test machine comes with 2GB of DDR3 RAM and is upgradable. It also comes with a Seagate Laptop Thin SSHD 500GB as a system drive.

I install two Seagate Barracuda Desktop HDD as RAID 1 in it.

Windows Storage Server 2012 R2 Essentials is a x64 Windows based on Microsoft Windows Server 2012 R2. In specification tab of Thecus W5000, you will see a comparison table of Workgroup, Standard, and Essentials. Essentials doesn’t support Hyper-V but is capable of being a Domain Controller of Active Directory.

Although WSS 2012 R2 Essentials is a x64 Windows, it is limited to 4GB of RAM due to processor architecture. Memory Limits for Windows and Windows Server Releases on Microsoft provides a clear explanation.

Both DWA-171 rev A1 and D-Link DWA-131 rev E1 are working properly.

QNAP TS-119PII

TS-119PII use a Marvell 88F6282 which is a single core ARMv5TE-compliant 32-bit processor with 256K L2 cache.

It comes with 512MB RAM and is not upgradable.

I install a single Seagate Barracuda Desktop HDD 500GB in it.

QTS is an embedded Linux developed by QNAP. This report test with 4.2.1 build 0217.

Compatible/Incompatible USB Wireless on QNAP Wiki contains a full list of known compatible/incompatible USB wireless. DWA-171 rev A1 is identified and working properly but only for 2.4GHz. It doesn’t work on 5GHz. Therefore, the max speed is 150Mbps. DWA-131 rev E1 is not compatible and therefore not identified by QTS.

Mac Mini Late 2012

I have upgrade my Mac mini to 16GB RAM and Seagate Laptop SSHD 1 TB which spins at 5400rpm and has a 8GB MLC cache.

According to System Information and macg.co：Mac mini (Late 2012)は11n/450Mbps/3ストリームに対応している on MACお宝鑑定団, the build-in AirPort Extreme 802.11n is based on Broadcom BCM43xx which is capable being up to 450Mbps at 5GHz on 40MHz bandwidth using 3×3:3.

I am not sure if 2.4GHz may support up to 450Mbps yet.

But there is one problem: the connection speed is 150Mbps with RT-AC51U at 2.4GHz. According to OSX Yosemite Wifi issues on apple support, it seems related to OSX 10.10. Only getting connection speeds of 130 with new Airport Extreme on 802.11n at 5ghz on MacRumors reports this issue with even earlier OSX.

Both DWA-171 rev A1 and DWA-131 rev E1 are working properly but you need to download drivers from Edimax for OSX 10.10. EW-7822UAC, EW-7811UTC, EW-7811UAC, EW-7811DAC, EW-7811USC are using the same Realtel RTL8811AU chip.

Test Method

It is detail explained in Prepare Your NAS File Transfer Performance Test with Mac OSX Client. I test both Samba and NFS.

I also add test results from Thecus W5000 with OSX client as reference.

Thecus W5000 with Mac OSX File Transfer Performance Report

Performance

Analyze

Mac mini‘s build-in 802.11n at 5GHz is faster than DWA-171‘s 802.11ac even has a slower connection speed. Both are slower than Fast Ethernet. It seems there are compatibility issue between DWA-171 and RT-AC51U or 802.11ac should be faster than 802.11n at 150Mbps.

If both using DWA-171‘s 802.11ac, though with higher theoretical bandwidth, it is actually slower than using DWA-171 on Mac mini and Fast Ethernet on W5000.

If Mac mini use its build-in 802.11n at 5GHz, Fast Ethernet on W5000 is faster than DWA-171‘s 802.11ac.

If Mac mini use DWA-171‘s 802.11ac, for W5000, Fast Ethernet is the fastest. Then comes DWA-171‘s 802.11ac at the same 5GHz. DWA-131 at 2.4GHz is so slow that I give up finishing the test.

TS-119PII with DWA-171‘s 802.11n at 2.4GHz is slower than Mac mini with build-in 802.11n at 5GHz or 802.11ac to W5000 with Fast Ethernet.

I already know there are compatibility issue between Windows Server 2012 R2 and OS X from Improving OS X SMB server share performance to Windows Server 2008R2 on JAMF Nation but it doesn’t seems the primary reason in this test.

Considering TS-119PII performs well with OS X, wireless real-world through-put and compatibility might be the issue. 16 款 802.11ac 路由器與網卡採購：要快還要穩，決戰2.4、5GHz 雙頻段 on 電腦王 also share the poor stability, performance, and compatibility experience for those using Realtek chips. Check on WikiDevi before you buy!

More Thoughts

I have learned it is more complex to test wireless transfer. The connection speed is not a constant and will change because of conflict, distance, and noise. Besides, compatibility among chips still needs to be improved.

Upsangel shares his real-world wireless throughput experience in 802.11AC路由Router選購技術攻略：不花冤枉錢的ac網絡架設指南 and 一分鐘了解什麽是802.11ac WIFI – 本年度買Router路由器必須瞭解的AC無線製式 as below:

802.11n	1T1R	2T2R	3T3R
Theoretical	150Mbps	300Mbps	450Mbps
Upsangel		~80Mpbs	~200Mpbs
802.11ac
Theoretical	433Mbps	867Mbps	1.3Gbps
Upsangel	~100Mpbs	~250 to 300Mpbs	~350Mpbs

Something is interesting. OS X is holding back the 2013 MacBook Air’s 802.11ac Wi-Fi speeds on ArsTechnica says the TCP window size stay within 64KB and limits file transfer speeds to about 21.2MBps when using wireless device. I think it’s worth the time to read for detail.

Using NFS to Share Files on Thecus Between OS X and Linux

April 9, 2015, 5:50 pm

≫ Next: Thecus N2520 with Mac OSX File Transfer Performance Report

≪ Previous: Thecus W5000 and QNAP TS-119PII with Mac OSX Wireless File Transfer Performance Report

I choose to use Network File System aka NFS to share files between OS X and Linux because it’s much faster than Samba. But there is one more thing I need to handle: file and folder permissions.

Allow Connection to NAS

ThecusOS 6 on Thecus is a graphical web interface for easier management.

First, you need to browse available shared folders in [Control Panel] → [File Sharing/Privilege] → [Shared Folder]. Use [Add] button to create or select the folder you want to share via NFS.

Then click [NFS] button to bring up Config NFS Share dialog. Use [Add] tab to create a new exports or [Edit] button to edit existing export. You cannot change Host Name once created.

You may use IP with Netmask to specific range with the same permission. Thanks for correction by Li-chih Wu in Facebook Group: QNAP Geek.

For example, if you want all IP between 192.168.1.1 to 192.168.1.254 with the same permission, use 192.168.1.1/24. Another is all IP between 192.168.1.5 to 192.168.1.6 with the same permission, use 192.168.1.5/29. Netmask on Computer Hope is a very detail explain and IP Calculator by Krischan Jodies may calculate for you.

For OSX, choose AIX in OS Support. This will generate insecure as a parameter in exports which is a NFS configuration files. According to Using Linux NFS with Other OSes on nfs.sourceforge.net, insecure will enable listening to ports higher than 1024. Because non-root users can bind ports above 1024, it’s less secured.

Here is an example configuration to export /NAS_Public on 192.168.2.* for OSX:

"/raid0/data/_NAS_NFS_Exports_/NAS_Public" 192.168.2.1/8(rw,fsid=2,no_root_squash,insecure,async,anonuid=99,anongid=99,no_subtree_check)

Last, choose root:root in ID Mapping. It’s easier for me to share among Linux, OSX, and Windows but less secured. Guest will have full access to this shared folder.

Mounting NFS volumes in OS X on Tech Republic is a good post for first-time OS X user. Automount NFS in OS X from Your Mac / Linux Guy explains with Lightweight Directory Access Protocol aka LDAP.

With these configurations, folder owner created on Linux and OS X are different owner and groups. But files created on one can be edit or delete by another, because guest have full access.

drwxr-xr-x+ 2   1000 users   4096 Apr  2 00:25 Linux
drwxrwxrwx+ 2 nobody nogroup 4096 Apr  1 22:34 Mac

File Permission and Squash Option

Because I want to have full access on files and folders on ThecusOS 6, I have to edit /etc/exports and change no_root_squash into all_squash.

Use exportfs -ra to reload export configuration as explained in Fix NFS privileges on Synology NAS on Linux and Unit tips. It’s the same to Synology DiskStation Manager. But you will have no right to remove anything created with no_root_squash, you may only read them.

drwxr-xr-x+ 2 nobody nogroup 4096 Apr  2 00:33 Linux
drwxr-xr-x+ 2 nobody nogroup 4096 Apr  2 00:33 Mac

Mount the Right Path

When your are in Config NFS Share dialog, you will see hint showing you how to mount the selected folder. Use NFS3 Mount point with Finder. You will see warning “You do not have permission to access this server.” if you use NFS4 Mount point.

How to Access a Shared Folder Locally with NFS on Thecus is a good step-by-step guide.

Here is an example to mount a shared folder NAS_Public at 192.168.1.116:

nfs://192.168.1.116/raid0/data/_NAS_NFS_Exports_/NAS_Public

Notes

This post only apply to ThecusOS 6. If you are using OS X as your NFS server, please refer to EXPORTS(5) on OS X Man Pages.

Thecus N2520 with Mac OSX File Transfer Performance Report

April 12, 2015, 5:50 pm

≫ Next: Firefox: My Missing Manual

≪ Previous: Using NFS to Share Files on Thecus Between OS X and Linux

Thecus Windows Storage Server 2012 R2 is slow with OSX but how about ThecusOS 6? It’s based on Linux and perform well in my previous tests. Maybe it is a better alternative solution if you preferred Thecus. Let’s see how it compete with others.

Thecus N2520 with ThecusOS 6

Thecus N2520 use a Intel Atom CE5315 which is a 1.2GHz dual-core SoC based on Berryville. It has 512KB L2 Cache , 32-bit PAE, and 1GB DDR3 RAM.

I install two Seagate Barracuda Desktop HDD as RAID 1 in it.

ThecusOS 6.1.17.1 for N2520 is a 32-bit Linux used in this test.

Mac Mini Late 2012

I have upgrade my Mac mini to 16GB RAM and Seagate Laptop SSHD 1 TB which spins at 5400rpm and has a 8GB MLC cache.

Test Method

It is detail explained in Prepare Your NAS File Transfer Performance Test with Mac OSX Client. I test both Samba and NFS.

I also add test results from Thecus w5000 and QNAP TS-119PII with OSX.

Performance

* Numbers in green means informal test.

Analyze

N2520 is faster on reading but slower on writing to W5000 in Samba. It catch up with TS-119PII in NFS, less than 10% difference. TS-119PII is top performer on all tests.

According to these numbers, Thecus WSS and ThecusOS 6 are slower than QTS when accessed by OSX via Samba.

These green numbers indicate no significant improvement with different Samba options in ThecusOS 6.

More Thoughts

TS-119PII has a 2.0GHz Marvell 88F6282 SoC with single drive while N2520 is a 1.2GHz Intel Atom CE5315 in RAID 1. It’s not fare to conclude ThecusOS 6 has Samba compatibility issue with OSX. I need more test with different models.

Quickly Reset the Hard Disk in your ThecusOS Device as New

April 16, 2015, 5:50 pm

≫ Next: QNAP TS-251 with Mac OSX File Transfer Performance Report

≪ Previous: Firefox: My Missing Manual

After testing NAS running ThecusOS 6, I want to clean my hard disk. Thecus provides a neat tool to do this job. It’s easier than resetting hard disk in QNAP.

Use Official Tool

This works only for N2310 N2520 N2560 N4520 N4560 with ThecusOS 6.

Download OS6_clean_HDD_up.zip and unzip. Copy all contents to an empty USB flash drive and boot your NAS with it. It will clean up the disk and power off automatically.

What Has Been Done

After unzip, factory_test.sh is the only executable script files found. Here is the script:

#!/bin/sh
###################################
### For OS6 bin file dd
###################################
## Must use folder gofactory
cp /etc/gofactory/dd.sh /tmp
rm -f /etc/gofactory
rm -rf /mnt2/gofactory
sync

sh /img/bin/clean_raid.sh

echo "Buzzer 1" > /proc/thecus_io
/img/bin/pic.sh LCM_MSG "Clean Disk" "Finish"
sleep 3
echo "Buzzer 0" > /proc/thecus_io

poweroff -f
exit

Unfortunately, I cannot find dd.sh nor clean_raid.sh using find in ThecusOS 6. It seems a different boot image will be mounted while booting with USB flash. Therefore, I don’t know what it has done.

≪ Previous: Quickly Reset the Hard Disk in your ThecusOS Device as New

We have seen QTS 4.2.1 Build 0217 for TS-119PII but QTS 4.1.3 Build 20150313 for QNAP TS-251 is different. The later support smb 3.0 in [Control Panel] → [Network Services] → [Win/Mac/NFS] → [Microsoft Networking] Tab → [Advanced Options] dialog] → [Highest SMB version]. Let’s see if it is compatible with OSX and faster.

QNAP TS-251 with QTS 4.1.3

TS-251 uses an Intel Celeron J1800 which is a 2.41GHz and up to 2.58GHz dual-core processor. It has 1MB L2 cache, Intel 64 Architecture, and supports up to 8GB DDR3.

The test machine comes with 1GB of DDR3 RAM and is upgradable. In this post, I test with 1GB and 8GB RAM to see the difference.

I install two Seagate Barracuda Desktop HDD as RAID 1 in it.

QTS 4.1.3 Build 20150313 for TS-251 is a 64-bit Linux used in this test. Unlike QTS for TS-119PII, it has many extra features like smb 3.0, Storage Manager, and etc.

Mac Mini Late 2012

I have upgrade my Mac mini to 16GB RAM and use a Seagate Laptop SSHD 1 TB which spins at 5400rpm and comes with 8GB MLC cache build-in to replace the slow hard drive.

Test Method

It is detail explained in Prepare Your NAS File Transfer Performance Test with Mac OSX Client. I test both Samba and NFS.

I also add test results from QNAP TS-119PII, Thecus N2520, and Thecus w5000 with OSX.

Performance

File transfer performance on QNAP TS-251 with Mac OSX via Samba with different smb.

* Numbers in green means informal test.

Analyze

TS-251 is fastest on all Samba tests. I see no big different to enable or disable Asynchronous I/O. It is recommend to disable if you don’t have an UPS connected to your NAS for data safety.

On NFS tests, TS-119PII is as fast as TS-251 on reading but much slower on writing.

For informal tests, smb 3.0/2.1/2.0 are similar but considerable faster than 1.0. Reading on TS-119PII is closer to TS-251 with smb but writing is still fall behind.

More Thoughts

For your information, I also test copy on the same Mac mini with Seagate Laptop SSHD 1TB. Reading and writing on the same drive is 34MB/s. Maybe Seagate Laptop SSHD becomes the bottleneck now.

You might also want to read QNAP TS-251 with Firmware 0612 and 8GB RAM File Transfer Performance Report to see its performance with Linux. It’s getting closer.

Analyze

TS-253 Pro is as fast as TS-251 on Samba smb 3.0 and NFS.

If you use cifs instead of smb in Finder, Samba is as slows as smb 1.0 on QTS even [Highest SMB version] is set to smb 3.0.

More Thoughts

If you cannot find smb 3.0 in [Highest SMB version] after upgrading firmware, try to reboot again or reinstall QTS again. Quickly Reset the Hard Disk in your QNAP Device as New explains how to remove QTS from your hard disks.

If using cifs is as fast as smb in Finder, maybe you are running at smb 1.0 on QTS.

Asustor focus on Intel processors only. They all made with metal case and looks solid. Let’s see how fast AS-602T could be with OSX.

Asustor AS-602T with ADM 2.4.0

AS-602T uses an Intel Atom D2700 which is a 2.13GHz dual-core processor with Intel Hyper-Threading Technology. It has 1MB L2 cache, Intel 64 Architecture, and supports up to 4GB DDR3.

The test machine comes with 1GB of DDR3 RAM and is upgradable to 3GB.

I install two Seagate Barracuda Desktop HDD as RAID 1 in it.

ADM 2.4.0 RFU6 for AS-602T is a 64-bit Linux used in this test. According to following information, I only know the build-in Samba is 4.0.19. Like QNAP TS-119PII, I cannot select smb version in [Services] → [Windows] → [File Service] Tab → [Advanced Options]. After contacting Asustor, I was informed current ADM supports smb 2.0.

Mac Mini Late 2012

I have upgrade my Mac mini to 16GB RAM and use a Seagate Laptop SSHD 1 TB which spins at 5400rpm and comes with 8GB MLC cache build-in to replace the slow hard drive.

Test Method

It is detail explained in Prepare Your NAS File Transfer Performance Test with Mac OSX Client. I test both Samba and NFS.

I also add test results from QNAP TS-253 Pro, TS-251, TS-119PII, Thecus N2520, and w5000 with OSX.

Performance

Analyze

AS-602T is faster to TS-119PII, Thecus N2520, and w5000 on all tests. When compared to TS-251 with 1GB on Samba and NFS, AS-602T is about 10% slower on Samba reading but 10% faster on NFS. About writing, it is 25% slower with Samba while 15% with NFS.

If you use cifs:// in Finder to mount Samba shared drive on AS-602T, reading is 35% while writing is 23% slower compared to smb://.

More Thoughts

It seems ADM doesn’t have Samba compatibility issue with OSX. Just don’t use cifs:// in Finder which will slow down performance.

Asustor AS-5102T with Mac OSX File Transfer Performance Report

May 3, 2015, 5:50 pm

≫ Next: Log Off Microsoft Dynamics CRM on Premise from Safari on OSX

≪ Previous: Asustor AS-602T with Mac OSX File Transfer Performance Report

Asustor focus on Intel processors only. They all made with metal case and looks solid. Let’s see if AS-5102T is faster than AS-602T with OSX.

Asustor AS-602T with ADM 2.4.0

AS-5102T uses an Intel Celeron Processor J1900 which is a 2GHz and up to 2.41GHz quad-core processor. It has 2MB L2 cache, Intel 64 Architecture, and supports up to 8GB DDR3.

The test machine comes with 4GB of DDR3 RAM.

I install two Seagate Barracuda Desktop HDD as RAID 1 in it.

ADM 2.4.0 RFU6 for AS-5102T is a 64-bit Linux used in this test. According to following information, I only know the build-in Samba is 4.0.19. Like QNAP TS-119PII, I cannot select smb version in [Services] → [Windows] → [File Service] Tab → [Advanced Options]. After contacting Asustor, I was informed current ADM supports smb 2.0. More related information about Samba and smb may be found in Samba Wiki: Samba3/SMB2.

Mac Mini Late 2012

I have upgrade my Mac mini to 16GB RAM and use a Seagate Laptop SSHD 1 TB which spins at 5400rpm and comes with 8GB MLC cache build-in to replace the slow hard drive.

I also add test results from AS-602T, QNAP TS-253 Pro, TS-251, TS-119PII, Thecus N2520, and w5000 with OSX.

Performance

Analyze

AS-5102T is faster than AS-602T in most tests especially on writing. AS-602T is 4% faster on NFS reading.

Compared to TS-253 Pro and TS-251 using smb 3.0 but with the same J1900, most are within 10% difference. Only TS-251 with 8GB RAM is 12% slower on NFS writing.

As you see in AS-602T, if you use cifs:// in Finder to mount Samba shared drive, reading is 35% while writing is 23% slower compared to smb://. Therefore, I test with smb:// only.

More Thoughts

The faster J1900 and more RAM in AS-5102T help to improve performance over AS-602T. Besides, the new VirtualBox on App Central should run faster with J1900.

It seems ADM doesn’t have Samba compatibility issue with OSX. The performance is as good as QTS with smb 3.0.

Active Directory Authentication is Kept in Keychain

If you choose to save you user name and password in Keychain while login into On-premises Dynamics CRM, you will automatically login every time browsing. Reset all password kept in Satari preference won’t help, you can never leave.

Remove Active Directory Authentication

Managing SSL Certificate Authorities on OS X on Tech Republic gives me a good idea to clear this authentication: use Keychain Access.

Just launch Keychain Access and right click on the name of your Dynamics CRM to delete. You are log out immediately!

Install Microsoft Dynamics CRM on VirtualBox From Scratch

May 10, 2015, 5:00 pm

≫ Next: Android USB Tethering Drops and Data Usage Crashes, try Reset

≪ Previous: Microsoft Office: My Missing Manual

I need to setup an test environment to learn Microsoft Dynamics CRM on my OS X. Here is my memo from installing and configuring Windows Server 2012 R2, SQL Server 2014, to Dynamics CRM.

Install VirtualBox and Create a Configuration File

Download VirtualBox and install it. Then launch and create a configuration file for Windows Server 2012 R2.

Choose [Other Windows (64-bit)] [Windows 20012 (64-bit)] in [Versions] in [Name and operating system] dialog.
Memory must more than 4096MB
Choose [Dynamically allocated] in [Storage and physical hard drive] dialog to allocate space when needed.
Mount Windows Server 2012 R2 iso file in [CD/DVD Drive] on [Storage] tab in [Settings]

Start this virtual machine to begin Windows Server 2012 R2 installation.

Windows Server 2012 R2 Installation

It’s pretty simple to install Windows Server 2012 R2 on an empty disk.

Choose [Windows Server 2012 R2 Standard Evaluation (Server with a GUI)]
Choose [Custom: Install Windows only (Advanced)]

After installation, it will power off automatically.

Install VirtualBox Guest Additions

From VirtualBox menu, choose [Devices] → [Insert Guest Additions CD Image…] to mount this CD image. Use [File Explorer] to run [VBoxWindowsAdditions.exe] to install integration tools and drivers.

After installation, you may mount a shared folder on host operating system in this virtual machine.

Now, you may copy SQL Server 2014 and Dynamics CRM installation files to this virtual machine via shared folder.

Add Extra Features and Configure Active Directory

After installation, you need to manually add several components in Windows Server 2012 R2 and setup a domain controller running Active Directory service.

Use [Server Manager] → [Add roles and features] to add extra components.
In [Installation Type] section, choose [Role-based or feature-based installation]
In [Server Selection], choose current virtual machine as the server.
In [Server Roles] section, select [Active Directory Domain Services], [Application Server], and [Web Server (IIS)].
In [Features] section, select [Windows Search Service], [.NET Framework 3.5 (includes .NET 2.0 anmd 3.0)] in [.NET Framework 3.5 Features] and [APS.NET 4.5] in [.NET Framework 4.5 Features (2 of 7 installed)].

After installing, you will see a flag with warning mark on upper right corner. Click and choose [Promote this server to a domain controller] to launch [Active Directory Domain Services Configuration Wizard].

Choose [Add a new forest] in [Deployment Configuration] and provide a valid root domain name, eg lab.org, for the test environment.

You will see several warning but it is okay to apply these changes. After reboot, your virtual machine will join this new domain.

Add Organization Unit and an Active Directory User for Reporting Service

Next is to customize our Active Directory.

First, add an organizational units aka OU using [Active Directory Users and Computers] utility as described in create a new organizational unit on TechNet.

Second, create a new user in above OU. Use [Member Of] tab in property dialog to add this user in [ReportingGroup].

Now, you have a proper configuration for Dynamics CRM.

Install SQL Server 2014

You need to download SQL Server 2014 from Microsoft TechNet Evaluation Center. Dynamics CRM doesn’t work with SQL Server Express according to its software requirements.

Launch [SQL Server Installation Center], choose [New SQL Server stand-alone installation or add features to an existing installation] in [Installation] section.
In [Setup Role], choose [SQL Server Feature Installation].
In [Feature Selection], select [Full-Text and Semantic Extractions for Search], [Reporting Services – Native], and [Management Tools – Complete]
In [Database engine Configuration], choose [Mixed Mode] and [Add Current User] as a SQL Server administrator.

Configure Reporting Service

Now, assign an Active Directory user for Reporting Services aka SSRS. It’s an requirement before installing [Microsoft Dynamics CRM Reporting Extensions Setup].

I am going to use the user account created in [Add Organization Unit and an Active Directory User for Reporting Service] as described earlier in this post.

Launch [Reporting Services Configuration Connection] and connect to your SQL Server.
In [Service Account] section, choose [user another account]. Provide user information created here.

If you didn’t assign Active Directory user for Reporting Services and fail in [Microsoft Dynamics CRM Reporting Extensions Setup], after above procedure, you may execute installation program [Organizational Unit.exe] in [SrsDataConnector] folder in your Dynamic CRM install directory to try again.

Install Microsoft Dynamics CRM Reporting Extensions on TechNet provides detail explain on this topic.

Install Dynamic CRM

Dynamics CRM is available on Microsoft Download Center. You may use one of the following 90-day trial keys for testing.

Workgroup Server 2015 (5 CAL limit): XY8GN-DF2MC-FV482-YM9YP-HH6H2
CRM Server 2015 (no CAL limit): C6BDP-T6NK9-8TXJP-36WTB-TXW7V

The first-time installation will update .NET Framework to 4.5.2, restart Windows Server before you try again.

In the next few steps:

Fill the server name running SQL Server in [Specify Deployment Options].
Select the OU which you have created earlier.
Choose [NT AUTHORITY\NETWORK SERVICE] for all service in [Specify Service Accounts].

Now, you have successfully install your Dynamics CRM.

Test Your Dynamics CRM

Browse localhost in virtual machine, you shall be able to see it now.

If you need some sample data, from upper left [Microsoft Dynamics CRM] choose [Settings]. Then choose [Settings] → [Data Management] → [Sample Data] to install.

Other Resource

There are many related posts explains how to install. Step by Step: Installing Dynamics CRM 2013 on Windows Server 2012 on MSDN Blog is also very useful.

Install Microsoft Dynamics CRM Front End Server and Back End Server roles on TechNet provides information to run Dynamics CRM on multiple servers.

Android USB Tethering Drops and Data Usage Crashes, try Reset

March 14, 2016, 2:00 am

≫ Next: My Favorite Android Apps and Preferred Mobile Settings

≪ Previous: Install Microsoft Dynamics CRM on VirtualBox From Scratch

The USB Tethering between my Asus Wireless Router RT-AC51U and Sony Xperia C3 which is runningAndroid 5.1.1 drops about every 30 minutes. And I also found the “Data Usage” in Settings always crashes every time I launch it after experiencing the unusual drop. Therefore, I assume they are related.

It’s not my data connection has been dropped, it is the connection between RT-AC51U and C3. I am sure because if I manually disable data connection on C3, USB Tethering is still enabled. Therefore, I assume the problem is about USB Tethering rather than data connection on C3.

Interesting, I cannot check the “Data Usage” in Settings after data connection begins to drop frequently. It always crashes the Settings App. Reboot my C3 doesn’t help. Wonder if someone has hacked to my device and block me from checking “Data Usage” to detect uncommon internet access.

To find out what’s going on, I uninstall every download apps and disable build-in app one by one. Strangely, C3 reboots itself every time after uninstalling or disabling an app and I have never being about to check my “Data Usage“.

Eventually, I decide to reset. Guess what, theUSB Tethering never drops again within 5 days.

I cannot solve my problem and seems reset is the only work around available.

My Favorite Android Apps and Preferred Mobile Settings

March 20, 2016, 5:55 pm

≫ Next: Reinstall Synology DSM

≪ Previous: Android USB Tethering Drops and Data Usage Crashes, try Reset

Gmail, Maps, Street View, YouTube are pre-installed on most Android devices. But there are apps comes with your mobile, some you need to install separately. Here is a list of my favorite apps. I also make a remove/disable list and share my preferred configuration.

Favorite Apps

Authy 2-Factor Authentication

Authy Inc

I preferred this over others because of multiple device and accounts support. It’s always good to have another Authy running on a different device in case of being lost or damaged.

When reinstalling Authy, enter your registered cell phone and choose USE EXISTING DEVICE to get verification. Then launch Authy on another device to Accept and enter YES to confirm. It will popup a dialog with “The new device was added”.

Now you may launch it on your new device but still need your backups password for Authy to decrypt accounts.

Whoscall

Gogolook

To Identify caller ID from database and block calls. Great time saver.

Pocket

Read It Later

Pocket has plugins for Firefox and Chrome. It helps to save web pages to the cloud and read later on any other device.

I preferred to enable both Dark theme, Use true black , and Justified Text for easier reading. Remember to select Removable as your Offline Storage Location to save precious internal storage.

Google Photos

Google Inc.

It simplifies photo browsing and uploading process. Unlike any ordinary digital camera, there’s no need to swap memory card to check photos. After uploading to cloud, I may check them in Google Drive and all my photos are backed up.

For first-time use, I need to click on [Settings] → [Auto Backup] and choose Standard size in [Backup Storage] → [Photo size] for unlimited storage.In some version, it’s called High quality in [Upload size].

Because I have unlimited mobile data plan, I also choose Over Wi-Fi or mobile network in both [Backup Settings] → [Back up photos] and [Back up videos] to upload.

My Sony Xperia C3 comes with Google+ Photos which has been Shut Down already. Please install the new Photos to use all features.

Instagram

Instagram

Shoot and share on both Instagram and Facebook immediately. Build-in filters helps to improve color tones.

The only missing is that it cannot utilize the camera button on C3.

SMS Backup+

Jan Berkel

To backup and restore SMS and call log.

It is very useful before resetting or transferring SMS onto another Android mobile. You need to connect it to your Google Account before backup. It will backup and restore from Call log and SMS labels in your Gmail.

Yahoo Mail

Yahoo

I have tried to use the build-in mail app as a client to Yahoo, but it mix spam with others. Seems better to use Yahoo Mail to save time.

Evernote

Evernote Corporation

On desktop systems, I use it for clipping web pages and keeping notes. Evernote helps to sync between mobile and desktop. It supports simple formatting to highlight

I have link it to Google Smart Lock and use Authy to pass the 2-factor authentication for safety.

Google Keep

Google Inc.

A neat tool to take text notes but becomes difficult to manage when you have many. Therefore, I will move those worth to keep to OneNote and keep frequently used in Keep.

OneNote

Microsoft Corporation

Rich text formatting and table support but with poor web clipping plugins for browsers. I also worry if it will become a resource monster in the future like others from Microsoft.

Audio Recorder

Sony Mobile Communications

MobiSystems

It comes as a pre-installed app with my C3. Don’t disable it or you won’t be able to manage files stored in internal memory.

Favorite Apps for Work Only

LINE

LINE Corporation

Most Taiwanese use it to message local people. People like it because they can track whether or not and when you have read it. Government officers and businessmen also use it on sensitive information and there is no sign to change.

Google Drive

I use it to backup and sync personal documents and files on different devices and systems.

Favorite Apps for Traveling

Google Sheets

Google Inc.

≪ Previous: Reinstall Synology DSM

You may use “ssh admin@[NAS IP]” to login DSM but not root. They are different user. Most configuration need root access to edit. You have to first ssh as admin then use “sudo su –” to root.

admin@DS214SE:/$ sudo su -

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

Password:

Login as root

After switching to root, use “synouser –setpw root [new password for root]” to give root a different password for security concern. Next time, you may login as root with your new password.

Change Default Password for MySQL/MariaDB and phpMyAdmin on NAS

I always need to look for the default password for MariaDB and phpMyAdmin in my NAS. There is no hint at all. Some even change the rules after upgrade. Therefore, I write a note here and share to save your time. This page would be continuously maintained.

Asustor

You don’t need to install MariaDB which is already build-in in ADM. Open Services → MariaDB Server, select “Enable MariaDB server”, and click “Apply” to launch.

If your application and MariaDB run on the same machine, there is no need to select “Enable MariaDB remote access”. More detail, please read Using NAS as your Database Server.

About phpMyAdmin, you need to register an Asustor ID in Settings → Registration. Then to install it from App Central first. In 2016/6/19, the phpMyAdmin is 4.0.1.

Default

	ADM 2.6.1 R5H1
MySQL	root/admin
phpMyAdmin	root/admin

Reset MySQL root Password in ADM 2.6.1

Open Services → MariaDB Server, click “Reset Password” then “OK” to confirm. It will remind you the password for MySQL has been changed into default “admin”.

Change Password for MariaDB and phpMyAdmin in ADM 2.6.1

Edit user privileges in phpMyAdmin 4.0.1

Form Field Validation in Visualforce Pages with Twitter Bootstrap

August 9, 2016, 3:05 am

≫ Next: Use a Toggle to Switch HotSpot Status on Android

≪ Previous: Change Default Password for MySQL/MariaDB and phpMyAdmin on NAS

I have successfully enabled validation for <input> but fail for <select> using HTML attribute on a Visualforce Page on Salesforce Sites at here. Maybe I need to use JavaScript for <select> validation.

My Twitter Bootstrap is 3.3.6 and jQuery is 2.2.4. I also disabled the build-in CSS in Visualforce but there are still some conflicts. I will write a more detail post about this topic.

<apex:page standardStylesheets="false" showHeader="false" sidebar="false">
<link href="{!URLFOR($Resource.bootstrap, 'bootstrap-3.3.6-dist/css/bootstrap.min.css')}" rel="stylesheet" media="screen"/>
<link href="{!URLFOR($Resource.bootstrap, 'bootstrap-3.3.6-dist/css/bootstrap-theme.min.css')}" rel="stylesheet"/>
<apex:includeScript value="{!URLFOR($Resource.jquery, '')}"/>
<apex:includeScript value="{!URLFOR($Resource.bootstrap, 'bootstrap-3.3.6-dist/js/bootstrap.min.js')}"/>

<input> Validation

HTML5 Form Validation Examples has a full description on validation related properties of <input>. I use required and type for easy validation.

You may also control the appearance when there is an error using validation states.

Here are some partial code:

<input class="form-control" id="last_name" required="true" maxlength="40" name="last_name" size="20" type="text" placeholder="請問貴姓？"></input>
<input class="form-control" id="email" required="true" maxlength="80" name="email" size="20" type="email" placeholder="請問分析報告要寄到何處？"></input>

<select> Validation

required doesn’t work here though it has been supported according to w3cschool.com. Remember to let the description item without value property in <option> according to Can I apply the required attribute to <select> fields in HTML5?

Here are some partial code:

<select id="00NG000000FVXly" name="00NG000000FVXly" required="true" title="Q1. How do you manage marketing/sales?">
    <option>-- 請從下列選項中擇一 --</option>
    <option value="a. Everybody works independently.">a. 他們各自獨立完成工作</option>
    <option value="b. Review reports and coach.">b. 我會訓練督導他們</option>
    <option value="c. They work as a team.">c. 他們會團隊合作</option>
</select>
