I reboot the Ubuntu server. Transmission Web UI is live for a while, then lost the connection. I went to the SSH window. Check the status of the service.

The service has failed.

After I checked Google, I found a workaround. It is not a solution, but works.

Edit /etc/systemd/system/transmission-daemon.service

Change the Type=simple

Then the file looks like below:

Done.

 

Reference:
transmission-daemon times out when launched by systemd

transmission-daemon fails to notify systemd of correct start

The post Transmission Daemon failed with timeout error appeared first on David Yin's Blog.

So I SSH to the VM. Run the command sudo apt update

I got the following error message

An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu focal InRelease: The following signatures were invalid: EXPKEYSIG 3F01618A51312F3F GitLab B.V. (package repository signing key) <packages@gitlab.com>

The error is invalid signatures: EXPKEYSIG 3F01618A51312F3F

My first idea is to delete this invalid signature.

sudo apt-key del 3F01618A51312F3F

Then I run the update again. Of course, another problem came.

It looks OK. But I found one line, Hit:1 https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu focal InRelease

Ubuntu Facal is Ubuntu 20.04. It is the old one. I don’t need it. So I go to /etc/apt/sources.list.d/, edit gitlab.list file. Commented the line with Facal.

Now I am satisfied.

OK. One another thing about the updated Gitlab. At the beginning, the Gitlab CE is version 16.91

I run the following to add/update the sources.

curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

Then, I run the sudo apt update and sudo apt upgrade to upgrade the Gitlab CE to the latest version 16.11.0.

PS.

Suddenly I noticed an error during the POST, and booting.

The error is reading:

A Start Job is running for dev-nas2-middleone.device.

I remembered that I have removed the second HDD from the NAS. It is named as “middleone”.

So I solve this problem in the terminal screen.

nano /etc/fstab

It solved the problem.

Here is the situation:

• Oracle VM Free Tier.  I selected the Image: CentOS-7-2020.04.21-0.
• For CentOS, SSH public key connection.  The user is OPC  when I try to ssh to it.
• Then I add a new user and add it to the group wheel.  the username is admin.
• Based on the How To Create a Sudo User on CentOS on DigitalOcean.
• I followed the installation guide on the Webmin support page. The ports 10000 to 10010 are opened.
• In the browser, I can see the login page.  But can not log in with the new user, admin.
• Check the error log of webmin at /var/webmin/miniserv.error
  The error message is missing  Perl module Authen::PAM 
• Then I install Authen::PAM in the ssh window.
• Try to login again. Still can not log in.
• I restart the server, and still can not log in.

The real solution is below:

/usr/libexec/webmin/changepass.pl /etc/webmin username password

Replace username by root, and with my own password.

After this command, I can log in the Webmin as root.

See the basic information of this VM.

Features:

• AMD EPYC 7551 32-Core Processor, 2 Cores
• 1GB RAM memory
• 40GB Storage
• CentOS 7.8
• Webmin 1.941

1) Close the Dreamweaver application.

2) Go to the following location:

Windows: C:\Users\[user name]\AppData\Roaming\Adobe\Dreamweaver CC xxxx\en_US\Configuration
macOS: ~/Library/Application Support/Adobe/Dreamweaver CC xxxx/en_US/Configuration

Here, xxxx is the version of Dreamweaver. For example, if you are using Dreamweaver 2017 running on Windows, then your folder location reads:

C:\Users\[user name]\AppData\Roaming\Adobe\Dreamweaver CC 2017\en_US\Configuration

3) Right-click the ssh_hosts file, and rename this file. For example, ssh_hosts_old.

4) Relaunch Dreamweaver and connect to your SFTP server.

Let me review the settings.

1) Make sure your Gmail account (Google Apps account) is working properly.

Sample below:

Gmail account: myname@gmail.com

Gmail password: 123456

You can sign in your Gmail from the browser, Chrome or Firefox, etc.

2) Enable POP

Forwarding and POP / IMAP. Under POP Download, click either Enable POP for all Mail, or Enable POP for Mail that Arrives Now (which ever suits your purpose). Configure anything else that appeals to you too. Exit from the Gmail Settings Window after saving your selections (this is important).

3) Settings in phpBB 3.2.x

Login the phpBB administrator panel.
Goto General Admin > Configuration > Email Settings
SMTP Server Address:tls://smtp.gmail.com
SMTP Ports: 465
Authentication method for SMTP: PLAIN
SMTP Username: myname@gmail.com
SMTP Password: 123456

After the above three steps, try to send email by forget password or register a new user.

Check the error log on the phpBB Admin panel.

There are may be erro 535 or error 534. The error looks like below:

At this point, you should go to change the settings of your Gmail or Google account.

4) Settings at Google

Enable less secure apps to access account

Sign in to your Google account

Click Security

On the bottom of the page, in the Less secure app access panel, click Turn on access.

Unlock Captcha

Sign in to your Google account

Open https://accounts.google.com/DisplayUnlockCaptcha link and click button to unlock Captcha

Now, the Gmail can handle the mailing from phpBB without errors.

Access denied for user ‘root’@’localhost’

mysqli_real_connect(): (HY000/1698): Access denied for user ‘root’@’localhost’

Here is the solution to make the root connect to a server without error.

First SSH to the terminal window of the Ubuntu 18.04.

Run the following command to check the MySQL root user’s information.

davidyin@example:~$ sudo mysql -uroot -p
[sudo] password for davidyin:
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 169
Server version: 10.1.38-MariaDB-0ubuntu0.18.04.1 Ubuntu 18.04

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.

MariaDB [(none)]> SELECT User, Host, plugin FROM mysql.user;
+——+———–+————-+
| User | Host | plugin |
+——+———–+————-+
| root | localhost | unix_socket |
+——+———–+————-+
1 row in set (0.00 sec)

I saw the root user is using unix_socket. I will change it to mysql native password.

MariaDB [(none)]> UPDATE mysql.user SET plugin=’mysql_native_password’ WHERE User=’root’;
Query OK, 1 row affected (0.11 sec)
Rows matched: 1 Changed: 1 Warnings: 0

MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.08 sec)

MariaDB [(none)]> exit;
Bye

Now, at this step, I can access Adminer and phpMyAdmin without any problems.

Another workaround I found by Google. Someone creates a new MySQL user and give the superuser permission to it.  Then use this superuser to access MySQL server.

They come from different IP addresses and with different User Agents.  Each of these IPs is only doing this, sometimes repeatedly.

They are just waste my server’s time and CPU.  How to stop them or reduce the effect on my VPS.

At the last I know why they do it and how to handle it.

Why they do it?

There were some exploits recently that used a favicon file that was maliciously uploaded. Likely this bot is trying to see if the server or site have it.

There is also another possible reason. It may from GFW.

How to handle these request?

I would like to just ignore them or block them when the IP try to access following URL.

/view/img/favicon.ico
/3/favicon.ico
/2/favicon.ico
/home/favicon.ico

Depend on the web server you use or the service you use, there are a lot of ways to do it.

Here is a sample of Nginx config to drop the connection to /2/favicon.ico

location = /2/favicon.ico {
return 444;
}

My current Windows 10 is version 1703, OS build 15063.674.

I knew OneDrive is the builtin with Windows 10. It can not be uninstall like a normal program.

After a little bit search, I found the answer, or solution of the error.

run

%userprofile%\AppData\Local\Microsoft\OneDrive\Update\OneDriveSetup.exe

After a brief re-installation, the app icon will show in my taskbar notification area as normal.

It annoied my half an hour to solve the problem. At last, I got the answer.

My Windows 10 may need a particular library file which is not included. It is Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC security Update.

Download here Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update

I download and install the x64 file. Then re-try the installation of iTunes, it is OK now. No Error comes out.

The post iTunes Installation error on Windows 10 appeared first on David Yin's Blog.

I did the following steps.

1. Download client installation file from World of Warships official site.
2. Run the installation and allow it to download related files and updated files.
3. Reboot the computer.
4. Click the icon and try to run the game.
5. An error comes out.

I tried a lot of ways to solve it. Only one works on my computer.

D3dx9_43.dll is a directX extension file. It is DirectX 9. 43 means version 43.

Let me show you how to do it.

1. Download the d3dx9_43.dll from Internet. Actually I got it from a dll file site.
2. Unzip it. There are two files, one is 32 bit, on 64bit.
3. I copy the 32bit file into c:/Windows/SysWOW64
4. Restart the computer
5. It works.

Now, I put the download link here, and help yourself if you need it.

It is not always happened. Click OK. The result is  done.  But, there are some testing files left in the c:\AS-SSD-TEST42\ folder. You can delete them manually.

If it happened, you just need to run the execute file with Administrator right.
