As you can see, since the update on Mac OS X 10.7 Lion, the system has lost the ability to enable an FTP server for sharing files and folders. It’s unclear why Apple removed the graphical interface for enabling FTP sharing, but you can still start a local FTP (or SFTP) server on macOS using the command line.
If you use the command line, you probably noticed that the latest versions of macOS do not have FTP file transfer protocol.
By default, FTP is not installed in the latest versions of the system, but this does not mean that you cannot install the protocol yourself. Modern versions of macOS use SFTP instead of FTP. SFTP has more secure encryption.
However, some users still prefer FTP. If you don’t need FTP, then there’s no reason to install it.
Aria2 is a lightweight multi-protocol & multi-source command-line download utility.It supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. Aria2 can be manipulated via built-in JSON-RPC and XML-RPC interfaces. Download version 1.35.0.There you can download source distribution and binaries for OS X, Windows and Android. The legacy releases earlier than 1.19.1 are available here. One Liners – Windows FTP Command Prompt. There comes a time as an IT Support Professional/MSP when sometimes you need to ftp from the command prompt and combine the username, password and file to download in one line without having to use a separate text file.
How to Install FTP in macOSMac Download Ftp Command Line Installer
If you still haven’t installed Homebrew on a Mac, you need to do this before proceeding with the instructions below.
We will do this by installing inetutils. And this is done through Homebrew. If you haven’t Homebrew in your system, you can take script for Homebrew installing here.
![]() Installation Using inetutils
The inetutils file contains: FTP, FTP server, telnet and telnet server, as well as rsh, rlogin, tfp servers and clients, etc. If you need FTP protocol, it will not hurt to install the entire set.
To do this, use the following command:
When Homebrew finishes installing inetutils, you can run the FTP command as usual. For example, you can connect to the gnu.org server to check that everything worked out.
One of the advantages of this method is that you also get other useful tools in the kit, and you will not need to install them manually.
How to Start FTP and SFTP Server in macOS
Naturally, it is possible to download a separate server and many do, but why, if the mac out of the box already has a built-in ftp / sptp server, which is enough for most tasks. Simply, the built-in server is disabled by default and we just need to enable it. This is what we will do.
Start FTP server in macOS
First, start the Terminal (/Applications/Utilities/Terminal.app) and run the following command:
Check if the server is working with the ftp localhost command. If you see something similar in the terminal window:
So everything turned out and the server works. To connect to the server, use your account or create a new one, especially for ftp connections (which will be more correct from a security point of view). To access files on the server, use the “connect to server” command in the Finder or using any ftp client.
Start SFTP server in macOS
As you know, the FTP server transmits data in unencrypted form and, as a result, for security reasons, it is not very reliable.
To exchange information securely, you need to use an SFTP server, for this:
You can also test the operation of this server using with command:
ATTENTION!!!
FTP and SFTP servers may conflict with each other and it is not recommended to keep them enabled at the same time.
Server Shutdown
The built-in SFTP server is disabled by unchecking the Remote login option in the system settings.
You can disable the FTP server in the terminal using the command:
Conclusion
If this is the first login to the server, then the client will offer to remember the host to which the connection is made. You can confirm this action by typing the word “yes” in the console and pressing the “Enter” key. Otherwise, type “no” and press “Enter”.
Next, you need to enter a password, if all the data has been entered correctly, the client will successfully connect to the server.

Description
The National Center for Biotechnology Information (NCBI) offers a wealth of databases analysis tools and reports for use in research by the medical and scientific community.
These resources are freely available to download from the NCBI website. Because of the large sizes of most of the datasets (on the level of gigabytes or terabytes) the recommended method of transfer is with the Aspera Connect browser plugin.
You can use Aspera Connect directly through the NCBI website on your browser by clicking and downloading the datasets of your choice.
Alternatively you can also choose to download data from NCBI through the command line with
ascp Asperas transfer tool which comes bundled with your Connect installation.
Usage
The general syntax for downloading data from NCBI is the following:
The components of the command can be broken down as follows:
Private key and ascp locations
The private key you will use is
asperaweb_id_dsa.openssh which comes with your Connect installation.
![]() Mac Download Ftp Command Line Command
Below are locations where you can generally find the private key and the
ascp executable. Where applicable replace usernamewith the name of the user you're logged in as.

Examples
The following examples demonstrate usage of
ascp to download real data from NCBI. Commands for Mac Linux and Windows will be shown with the assumption that we are downloading from a user account on the system named janedoe and downloaded data will go to the folder NCBI_data in janedoes home directory. The path locations of the datasets are shown on NCBI's public download directory.1. Say you need to download all the data NCBI offers on epigenomics. There is a 223.79 GB sized folder on the topic containing 5 subfolders worth of data. In order to download the entire folder via ascp you would use the following command:
On a Mac:
On a Windows:
On Linux:
2. Perhaps you are conducting a study on tree-dwelling lizards and want to examine the genome data NCBI offers for the Anolis carolinensis species. To download the genome data for this species you would use the following command:
On a Mac:
On a Windows:
On Linux:
3. As part of a research paper youre writing you need to look at NCBIs RefSeq project data concerning protein and RNA sequencing data in humans. You know there is 1.69 GB worth of available data on NCBI and you proceed to download it with the following command:
On a Mac:
On a Windows:
On Linux:
4. Another Windows example an actual command line and the file download status:
