You may get this error when you try to access MySQL server on Windows.

Solution:

1. Stop MySQL service (from services.msc)

2. Create a text file in C:\ called “init.txt”. Paste the following code and save it.

GRANT ALL PRIVILEGES ON mysql.* TO root@localhost IDENTIFIED BY 'YourPassword!' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON mysql.* TO root@127.0.0.1 IDENTIFIED BY 'YourPassword!' WITH GRANT OPTION;

3. Open command prompt (cmd)

4. Go to MySQL bin directory on cmd.

Example: C:\Program Files\MySQL\MySQL Server 5.1\bin

So I assume you did previous installations. Now let’s go with FFmpeg-PHP installation.

1. Download ffmpeg-php in to /usr/src directory.

You may get this error when you add WMI sensor on Paessler PRTG Monitor.

Probably there is a firewall between servers or target server is behind the NAT. Solution is modifying “hosts” file of Windows.

Modify “hosts” and type like “10.10.10.10 %hostname%”. Hostname is the computername of Windows machine.
