Filezilla will not connect to server using Secure File Transfer Protocol (SFTP)

Filezilla will not connect to server using Secure File Transfer Protocol (SFTP)

Symptom(s):

Filezilla is unable to connect to the server using the Secure File Transfer Protocol (SFTP), however regular file transfer protocol (FTP) works fine. Additionally, you have confirmed that the required ports for the Secure File Transfer Protocol have been enabled on the firewall. The generic port for SFTP is port 22 and the port for FTP is 21, port 20 may be required if the server is running the ftp services in passive mode.

Solution(s): 

  1. SSH into the server and edit the /etc/ssh/sshd_config file, if your config is in another location you can use the “locate sshd_config” to identify that location.
  2. Once in the file find the following commented out line: #Subsystem sftp /usr/lib/openssh/sftp-server Leave the line commented out, if its not commented, go ahead and comment it out using a hash tag (#).
  3. Below the commented out line add: Subsystem sftp internal-sftp  then reboot the server.
  4. Your Filezilla should now be able to connect.
