How to Allow MySQL Client to Connect to Remote MySQL server

Issue: How do I allow a MySQL client to connect to a MySQL database server?

Solution: By default, MySQL does not allow remote clients to connect to the MySQL database.
If you try to connect to a remote MySQL database from your client system, you will get the “Host is not allowed to connect to this MySQL server” message as shown below.

$ mysql -h 192.168.1.8 -u root -p
Enter password:
ERROR 1130: Host '192.168.1.4' is not allowed to connect to this MySQL server

You can also validate this by doing telnet to 3306 mysql port as shown below, which will also give the same “host is not allowed to connect to this MySQL server” error message.

$ telnet 192.168.1.8 3306
host 192.168.1.4 is not allowed to connect to this mysql server

If you want to allow a specific client ip-address (for example: 192.168.1.4) to access the MySQL database running on a server, you should execute the following command on the server that is running the MySQL database.

$ mysql -u root -p
Enter password:
mysql> use mysql
mysql> GRANT ALL ON *.* to root@'192.168.1.4' IDENTIFIED BY 'your-root-password';
mysql> FLUSH PRIVILEGES;

Also, update firewall rules to make sure port# 3306 is open on the server that is running the MySQL database.


After the above changes, when you try to connect to the MySQL database from a remote client, you’ll not get the “Host is not allowed to connect to this MySQL server” error message any more.

How to Install vsftpd on Ubuntu and Add New User

Warning: FTP is inherently insecure. If you must use FTP, consider securing your FTP connection with SSL/TLS. Otherwise, it is best to use SFTP, a secure alternative to FTP.

The first two letters of vsftpd stand for "very secure" and the program was built to have strongest protection against possible FTP vulnerabilities.

Step One—Install vsftpd

You can quickly install vsftpd on your virtual private server in the command line:

sudo apt-get install vsftpd

Once the file finishes downloading, the VSFTP will be on your droplet. Generally speaking, it is already configured with a reasonable amount of security. However, it does provide access on your VPS to anonymous users.

Step Two—Configure vsftpd

Once vsftpd is installed, you can adjust the configuration.

Open up the configuration file:

sudo nano /etc/vsftpd.conf

The biggest change you need to make is to switch the Anonymous_enable from YES to NO:

anonymous_enable=NO

Prior to this change, vsftpd allowed anonymous, unidentified users to access the server's files. This is useful if you are seeking to distribute information widely, but may be considered a serious security issue in most other cases.

After that, uncomment the local_enable option, changing it to yes and, additionally, allow the user to write to the directory.

local_enable=YES

write_enable=YES

Finish up by uncommenting command to chroot_local_user. When this line is set to Yes, all the local users will be jailed within their chroot and will be denied access to any other part of the server.

chroot_local_user=YES

Save and Exit that file.

Because of a recent vsftpd upgrade, vsftpd is "refusing to run with writable root inside chroot". A handy way to address this issue to is to take the following steps:

Create a new directory within the user's home directory

mkdir /home/username/files

Change the ownership of that file to root

chown root:root /home/username

Make all necessary changes within the "files" subdirectory

Then, as always, restart:

sudo service vsftpd restart

Step Three—Access the FTP server

Once you have installed the FTP server and configured it to your liking, you can now access it.

You can reach an FTP server in the browser by typing the domain name into the address bar and logging in with the appropriate ID. Keep in mind, you will only be able to access the user's home directory.

ftp://example.com

Alternatively, you can reach the FTP server on your virtual server through the command line by typing:

ftp example.com

Then you can use the word, "exit," to get out of the FTP shell.

Adding New Users To vsftpd

I found it rather strange that there arent any good tutorial that can explain how to add new users to vftpd. Google gives few results but most of them are trial and error method. So i decided to write this post after spending 1 hr trying to accomplish this simple task.

#edit /etc/vsftpd.conf or /opt/etc/vsftpd.conf
Open the vsftpd.conf file and search for chroot_list_enable=YES
Make sure it is YES. Do the same for the following variables
chroot_list_file=/etc/vsftpd.chroot_list or /opt/etc/vsftpd.chroot_list
chroot_list_enable=YES
Save and close the file

Create vsftpd.chroot_list in /etc/ or /opt/etc/
Add the username you want to export to ftp.
IMP: The user must already be a system user with a valid passwd. You must be able to find /home/
If the user you want to add is not a system user then create that user first before editing the above file.
#adduser 
#passwd 

Restart the vsftpd server using /etc/init.d/vsftpd restart or service vsftpd restart
Now you can log into ftp using the new user.

How do You Install XvidCap on uBuntu 12.04 Distro

Xvidcap is a small tool to capture things going on on an X-Windows display to either individual frames or an MPEG video. This software is not present in the Ubuntu 12.04 repository by default. You can get a copy of the distributed binary in the form of a .deb package at the following link.

https://launchpad.net/ubuntu/precise/amd64/xvidcap/

Once you download this package, go ahead and install the package with the following command. The amd64 package given as example is for 64 bit machine.

$ sudo dpkg -i xvidcap_1.1.7-0.2ubuntu12_amd64

In case if the above command fails giving out errors, please note that Xvidcap depends on libavdevice-extra-53 package. So go ahead and install this package first with the following command.

$ sudo  apt-get install libavdevice-extra-53

By default, the Ubuntu 12.04 comes with libavcodec53 package. This conflicts with the  libavdevice-extra-53. In such a case, feel free to go ahead and replace the libavcodec53 package with libavdevice-extra-53. This satisfies the dependency requirement for Xvidcap.

Once done with setting dependencies, you can then install the Xvidcap package.

How To Stop Wi-Fi Stealing And Catch That Person

Wifi stealing is the common problem we face in our everyday life. It even happens without our knowledge. However the control is in our hand and we can stop wifi stealing using the admin panel of our wifi router.

O

ften we are unable to locate an uninvited user who uses our Wi-Fi. If someone uses our wifi without our knowledge, that would be termed as wifi stealing.

Whatever be the case, to be on the safer side, we must know who is using my Wi-Fi without my permission and how can we stop them. So, here are the steps on –

How To Stop Wifi Stealing And Catch That Person:

Login to your router.

Different routers support different login styles. So, I am listing a few of the logging in style, out of these, one might work for you:

• Punch in the IP address of your router in your browser address bar directly like 192.168.0.1 or 192.168.1.1
• If the above address does not work, you can also tryrouterlogin.com and it will redirect to your router admin panel.
• Enter the administrator username and password.
• Once you are inside the admin panel, look for menu options like ‘Connected devices’ or ‘Attached devices’.
• If you are able to find that menu, you can see the MAC Address, IP Address and Device name of all the devices which are connected to your network. This is how my Attached devices looks like.
• If you see some extra person’s name or some extra device then they are the one who might be using your wifi without your permission. Read on to know the steps to stop wifi stealing.

How to stop someone from wifi stealing?

Once you come to a conclusion that someone else is making use of your Wi-Fi resources, you can simply change the password of your Wi-Fi to a stronger password. You can also switch off your SSID broadcast.

If you want a stricter action, you can set up a filter based on the MAC address of the devices.
