How to Stop FTP Server on Ubuntu

If you're using an FTP (File Transfer Protocol) server on your Ubuntu machine, you may want to know how to stop it from running. This can be useful if you no longer need to use the FTP server or if you're experiencing issues with it.

To stop the FTP server on Ubuntu, follow these steps:

1. Open a terminal and type `sudo apt-get purge vsftpd` to uninstall the vsftpd package.

2. If you want to disable the FTP server without uninstalling it, you can use the following command: `sudo systemctl stop vsftpd`

3. Once you've stopped the FTP server, you can restart your machine if necessary.

Defining Authorized Networks and Cache Directory

Before stopping the FTP server, you may also want to define which clients can access the server by specifying the authorized networks. This is done by opening the `/etc/apt-cacher-ng/nf` file in a text editor and modifying it accordingly.

Additionally, you'll need to specify the cache directory where package files will be stored. This can be done by adding the following line to the configuration file: `cacheDir /path/to/cache/directory`

Using an Apt-Cache Server

An Apt-Cache server can help streamline package installations, reduce bandwidth usage, and increase system performance. To set up an Apt-Cache server on Ubuntu 14.04 Server using Apt-Cacher-NG, follow these steps:

1. Download the Apt-Cacher-NG package using a package manager such as apt-get.

2. Open the configuration file `/etc/apt-cacher-ng/nf` in a text editor and modify it to include the authorized networks and cache directory.

3. Update the package listings on the clients by including the IP address of the Apt-Cacher-NG server in the `sources.list` file.

4. Restart the service to apply the changes.

By following these steps, you can set up an Apt-Cache server on your Ubuntu machine and enjoy faster package installations and reduced bandwidth usage.
