To configure SFTP connection logging, follow these steps:
1. Open your SFTP server configuration file, usually located in /etc/ssh/sshd\_config.
2. Locate the section that refers to logging and uncomment the line that reads “Subsystem sftp /usr/lib/openssh/sftp-server” (or a similar path).
3. Add the following line below it:
1. Save the file.
2. Restart your SFTP server process to apply the changes.
With these settings in place, the SFTP server will log connection attempts and actions taken by users to the server’s system log, typically located in /var/log/auth.log or /var/log/secure. You can use standard log analysis tools to view and analyze these logs.
