Local SFTP Server for Testing

This documentation guides you through setting up a simple SFTP server implemented using the Apache Mina SSHD library, Java, and Spring Boot. This server is designed for testing.

Starting the Server

To start the server, you can either run the SftpServerApplication.java class from your IDE or use the following commands from the command line:

mvn clean install
mvn spring-boot:run

Testing SFTP Session

Execute the following command to test the SFTP session. The password is 'password'.

sftp -oPort=2222 foo@localhost

The first time you run this command, it will prompt you to add the host key to your local ~/.ssh/known_hosts file. You can now retrieve the saved host key from your known_hosts file for use.

Example prompt:

The authenticity of host '[localhost]:2222 ([::1]:2222)' can't be established.
RSA key fingerprint is SHA256:0lUTPTgivp12WiWr/6O+9BEiU1sAkzCneIlAnTNntU4.
Are you sure you want to continue connecting (yes/no)?
