Zoom Quit Unexpectedly Cannot Start Meeting

WebBanshee — Thu, 25 Nov 2021 08:42:04 +0000

Hello, fellow Zoom users! Yesterday I had a problem where Zoom quit unexpectedly a couple of seconds after I launched the application on a Windows 10 Version 20H2 machine.

Nonetheless, I was able to log in and noticed that the Zoom quit unexpectedly message returned permanently. Starting a meeting was not possible and I could not access the settings.

Updating graphic card drivers had no effect, Zoom kept crashing. The solution was simple once I got some hints from the Zoom log.

I’ll keep it short:

Scenario: You start Zoom and a couple of seconds after you started it the following message appears:

You are able to log in but the Zoom quit unexpectedly message reappears and you are not able to start a meeting or get into the settings. No events are written into the application log.

However, I was sure Zoom logs something so I started to google the location of the logs and found this.

You can find the logs under the path below:

C:\Users\YourUser\AppData\Roaming\Zoom\logs\

Open the crashrpt.xml and focus on the information within the exception tags.
The following lines gave me a hint:

This is the base for the next Google query. Search for:

quartz.dll 0xc0000005

Soon or later you will find this article where the comment of DaedalusWONG will point you to Microsoft Power Toys as the culprit.

A more detailed description of this Power Toys bug can be found here.

Indeed, I have Power Toys version v0.49.1 installed.

Open Power Toys as an admin and disable Video Conference Mute:

Disabling Video Conference Mute solved the problem straight away.

I hope this compiled information helps when you run into this problem and need a fast solution.

Stay healthy!

Remove RAID on Synology DS218

WebBanshee — Wed, 22 Apr 2020 06:16:00 +0000

Please take into account that this description is based on a new Synology NAS setup. The disks did not contain any data and this post was written to remove RAID after the initial setup finished with RAID active.

If you decide to follow the steps below with disks that contain data backup your data before and read the comments at the end of this post. Do it at your own risk.

A couple of weeks ago I bought a Synology DS218+ NAS with two 2TB WD Red disks. After the initial setup, I wanted to remove RAID on Synology DS218 since we use the NAS mostly for streaming films.

I am not deep into RAID configurations and this is my first Synology NAS. So it was not straight away clear how to remove RAID on Synology DS218. I did not want to waste 2TB of usable disk space so I started to dig.

If you initially choose an automatic setup ( as I have done ) your disks will be configured in RAID. To remove RAID I needed to remove the volumes, delete the storage pool, and set up the disks as individual disks.

To be able to delete the storage pool I needed to uninstall the Synology DSM packages that have been installed on the volume I wanted to remove first. The name of those packages is listed when you choose a volume and click remove in Storage Manager within the Volume tab.

After you have uninstalled the listed packages via Package Manager > Remove the volume.

Now delete the storage pool > Confirm with password

Create a new storage pool on each of your drives..

In the Storage Pool Creation Wizard I have chosen more flexibility which supports multiple volumes. I see an average 110 MB Read and 93 MB Write performance with this setup.

Next > Storage Pool properties > RAID type basic and 1 drive per RAID

Confirm settings

Since both disks were brand new I didn’t choose drive check.

Then I started to create new volumes from Storage Manager > Volume tab > Create
With a basic storage pool setup you can only choose Custom:

Choose an existing storage pool:

Assign a storage pool:

Specify the size of the volume:

Choose a file system. I have chosen ext4. You can find additional information here.

Confirm settings

I have repeated these steps for every new volume.

Stay safe!

Different Memory Types

WebBanshee — Thu, 02 May 2019 16:05:03 +0000

For my birthday in two weeks, I decided to make myself a present and extend the memory capacity of my PC. For a long time I wanted to build a more decent test lab at home to run a DC and minimum one Exchange Server and today is the day! In the end my solution was a combination of two different memory types.

My late 2016 PC configuration had 2x 8GB Kingston HyperX DDR4 2133 Mhz HX421C14FB2/8 RAM sticks installed. The optimal solution would have been to get 2x 16GB sticks of the same Kingston HyperX series. Unfortunately, this series has been discontinued.

I was not sure if another HyperX series would match with the installed sticks. The HyperX Predator 2x16GB 2666Mhz HX426C13PB3K2/32 caught my eye. After some further readings, I ordered these two 16GB sticks. Got them today and placed them instantly in their slots.

My thoughts were: In the worst case the 2 RAMs do not match and I stay with 32GB of the new RAM. When everything goes fine 48GB of memory will smile on me from the task manager

The composition of different memory types was as follows :

DIMM_A1: HyperX DDR4 2133 Mhz HX421C14FB2/8 ( old RAM stick )
DIMM_A2: HyperX Predator 2x16GB 2666Mhz HX426C13PB3K2/32 ( new RAM stick )
DIMM_B1: HyperX DDR4 2133 Mhz HX421C14FB2/8 ( old RAM stick )
DIMM_B2: HyperX Predator 2x16GB 2666Mhz HX426C13PB3K2/32 ( new RAM stick )

Result: The PC didn’t boot.

No problems on boot when only the new RAM or only the old RAM was installed.

Changed the sticks and the slots and set the frequency and voltage manually in BIOS:

DIMM_A1: HyperX Predator 2x16GB 2666Mhz HX426C13PB3K2/32 ( new RAM stick )
DIMM_A2: HyperX DDR4 2133 Mhz HX421C14FB2/8 ( old RAM stick )
DIMM_B1: HyperX Predator 2x16GB 2666Mhz HX426C13PB3K2/32 ( new RAM stick )
DIMM_B2: HyperX DDR4 2133 Mhz HX421C14FB2/8 ( old RAM stick )

Ram Frequency: 2133 Mhz – which is absolutely enough for my needs and the lowest frequency in the chain. The Predator sticks with 2666 Mhz will adapt the manually set values and run with 2133 Mhz and 1.2v defaults.

Voltage: 1.2v

Result:

… and stable for the last 24 hours stressed with several Virtual Machines.

This is what worked for me. Most probably not every RAM and Brand combination will match when you use different memory types. Should you try it with other variations try it with the specs of the weakest part ( RAM ) entered manually in your BIOS.

Install Transmission on ASUS Router

WebBanshee — Fri, 05 Apr 2019 15:39:27 +0000

Hello folks, after I flashed the firmware on my RT-AC87U to Asuswrt-Merlin and installed Entware the next step was to install Transmission.

To install Transmission takes just a few minutes and is well documented on Entware’s GitHub site. Further down I focus on the settings you can change in the configuration.

Install Transmission:

opkg install transmission-web transmission-daemon-openssl transmission-remote-openssl

Connect to your router via SSH and stop the Transmission daemon :

/opt/etc/init.d/S88transmission stop

It is important to stop the Transmission daemon before editing the configuration settings in the settings file. Otherwise, your changes will be overwritten by the default settings you have in place.

Determine your mount label which you will need to specify the dir paths:

ls -l /tmp/mnt

Edit the Transmission Config File under /opt/etc/transmission/settings.json :

To edit the settings file I usually connect with WinSCP to the router and use the integrated WinSCP editor. Of course, you can use Nano or other tools as well.

I have changed the following lines:

“cache-size-mb”: 2,
“download-dir”: “/tmp/mnt/LABELNAME/DownloadDir“,
“incomplete-dir”: “/tmp/mnt/Main/LABELNAME/IncompleteDownloadDir“,
“peer-limit-global”: 40,
“peer-limit-per-torrent”: 10,
“rpc-authentication-required”: true,
“rpc-enabled”: true,
“rpc-password”: “PASSWORD“,
“rpc-username”: “USERNAME“,

Here are some notes to the lines above:

“cache-size-mb”: This is the cache size for each peer ( ! ). If you have a peer-limit-per-torrent of 10 and cache-size-mb set to 2 the cache size will be 20 MB per torrent. Take this in account when you configure the cache-size-mb. Ideally, the cache size should be within your available memory, otherwise the cache will be written to the disk of your USB storage which will slow down the download speed.

“peer-limit-per-torrent”: This is the second parameter you can modify to optimize download speeds. If you get fast peers and you lower this limit you could increase the cache-size-mb to download bigger chunks which increases the download speed.

“peer-limit-global”: Specifies the over all peer limit. If you have 6 torrents with peer-limit-per-torrent set to 10 and peer-limit-global set to 40 the peers will max out at a number of 40 and will not reach 60 peers ( 10 peers per torrent ).

“download-dir”: ” Specify the path where your downloads should go to. This is why you need to know your LABELNAME stated in Step 3. Syntax : /tmp/mnt/LABLENAME/YourDownloadFolder

“rpc-enabled”: Enables the Transmission WebGui

“rpc-password”: Set the password to the WebGui. After you save the settings file and start the Transmission daemon the pw will be stored as hashcode ( no plaintext )

“rpc-username” : Set the username for the WebGui login. Can be different from your router admin password.

You can find a list of further Transmission parameters here: Transmission Config

Open Transmission port on your router:

Downloads without opening the Transmission port ( default is 51413 ) were fast and I didn’t experience any problems. When it came to seeding upload speeds were only in kilobyte ranges. Checking the Transmission port showed the port was closed.

Permanently open the Transmission port:

I followed the steps from the Tranmission GitHub site.

Create a script in /jffs/scripts/ using Nano or WinSCP.
Name the script firewall-start.
If you already have a firewall-start script just insert the lines below and omit the first line.
Using Nano: nano -w /jffs/scripts/firewall-start
Find Nano basics here.

Insert these lines into the firewall-start script:

#!/bin/sh

iptables -I INPUT -p tcp --destination-port 51413 -j ACCEPT

iptables -I INPUT -p udp --destination-port 51413 -j ACCEPT

Make the script executable:

chmod a+rx /jffs/scripts/firewall-start

Start the script manually: ( the script will autom. start when the router reboots )

/jffs/scripts/firewall-start

The port is open now:

Start the Transmission daemon:

/opt/etc/init.d/S88transmission start

This is how I managed to install Transmission and have configured it for my needs.
You can find further useful information on the Entware GitHub page

Happy downloading!

Install Entware on ASUS Router RT-AC58U

WebBanshee — Wed, 13 Mar 2019 03:59:49 +0000

Last week my Asus RT-N65U router just gave it up after 6 years of good service. For this reason, I was in an urgent need for a new router and jumped straight into the project to buy a new one. No reading through reviews and no feature and specs comparison as I normally do. Finally, I got my hands on an Asus RT-AC58U and here is how I managed to install Entware on ASUS router RT-AC58U.

The router comes with a quad-core processor ( wow ), offers concurrent speeds up to 400Mbps on 2.4Ghz and up to 867Mbps on 5GHz. It has 128MB of Memory ( could be more ) and most importantly has a USB 3.0 port to attach a storage device.

Since this post is no review of the router itself, I wrap it up a little bit. Let me just say, after I went through all steps to install Entware and satisfy my needs I still was disappointed with the multitasking performance of this router. Read the conclusion at the end of this post.

My requirements:

Being able to flash custom firmware without opening the chassis.
Install Entware on it.
Install a transmission torrent client on it.
Downloads and uploads should be performed directly from the attached storage without the need to turn on my PC.
Install MiniDLNA on it. ( the Asus one is a pain )
Being able to configure a disk spin down on the USB attached hard drive after a specified idle time.

The facts:

A custom firmware like Asus-Merlin cannot be installed since the Qualcomm quad-core processor is not supported. I did not want to open the chassis to install OpenWRT and all other solutions seem a little bit odd to me.
The router comes with no torrent client at all. Download Master is not installed. ( which is a positive in my case since Optware and Entware are not compatible with each other. So I was able to start from scratch straight away )
No option to configure a disk spin down. ( to be honest, I was prepared for this, no surprise )

The solution for me was to install Entware going through the steps I compiled below. I am not deep into Linux, just have collected and tested several solutions and want to share what worked for me.

Mount your USB device where entware will be installed.

It should be ideally formatted as EXT format. My drive is formatted ext4. I had never any problems with Asus routers and USB storages formatted as ext4.

Disable the Asus default media server :

Enable SSH on RT-AC58U under Administration > System:

It is recommended to specify an Auto Logout value. I have just disabled it for the time installing and testing entware, transmission and miniDLNA.

Connect via SSH to the router:

You will need a SSH client to be able to control your router via command line. I use PUTTY for this purpose. Assuming you connect to the router with the default IP type 192.168.1.1 under Host Name ( or IP address ). Leave it on Port 22. Connection Type SSH. Save the session for more convenient future use or just open it. Use your admin ceredentials to log in.

Since JFFS is not enabled on this router post-mount scripts cannot be utilized. We need to prepare persistence after a reboot as follows:

( find your LABELNAME by typing mount or ls -l /tmp/mnt )

cat << EOF > /tmp/script_usbmount.tmp
if [ \$1 = “/tmp/mnt/LABELNAME” ]
then
ln -sf \$1 /tmp/opt
/opt/etc/init.d/rc.unslung start
fi
EOF
nvram set script_usbmount=”`cat /tmp/script_usbmount.tmp`”

cat << EOF > /tmp/script_usbumount.tmp
if [ \$1 = “/tmp/mnt/LABELNAME” ]
then
/opt/etc/init.d/rc.unslung stop
fi
EOF
nvram set script_usbumount=”`cat /tmp/script_usbumount.tmp`”

nvram commit
reboot

Source for this one and the next one: Entware-Install-on-Asus-stock-firmware

Reboot the router and install entware:

wget -O – http://pkg.entware.net/binaries/armv7/installer/entware_install.sh | sh

Now you will be able to install a Transmission torrent client!!

Conclusion after I installed Entware, Transmission and miniDLNA on this router :

It worried me when I started to use Transmission and the RAM usage reached levels from 95 – 98 % straight away. Felt that I will not be able to stream a film via miniDLNA while the Transmission daemon is started. And unfortunately, I was right. MiniDLNA stopped working as soon the memory usage reached 100%. To my dissatisfaction, this happened quite often. As a workaround, I stopped the Transmission daemon and hoped to enjoy a film without any interruption. Nope. MiniDLNA got still disconnected. Not that often as before but it was still an annoyance. This was the point where I reset the router to its initial state and brought it back to the shop the next day.

It has obviously a cause that this router comes without the option to install Download Master via the default firmware. I can imagine using the router with a NAS and its own bit torrent client could be a good solution. Apart from that, the router offers good and reliable speeds on both networks. To be fair I must admit that Transmission version 2.94 which I had installed on this router consumes a considerable amount of memory more than the Transmission version I had installed on my old router ( it must have been 2.30 or lower ).

Any way this router did not fit my needs. My new one is an ASUS AC-87U with 256 MB of memory. This one flashed with Merlin, fits all my needs listed under ‘My requirements’
