Ensure sftp-server arguments are configured

VisokaNivo 1Automatskaaix

Opis

The sftp-server is started by the sshd server after authentication has been completed successfully. The process runs with the euid of the authenticated user. The sftp- server does not inherit the logging levels from sshd and they must be configured manually. SFTP provides several logging levels with varying amounts of verbosity. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).

Edit the /etc/ssh/sshd_config and set the sftp arguments to one of the following: Subsystem sftp /usr/sbin/sftp-server -u 027 -f AUTH -l INFO - OR - Subsystem sftp /usr/sbin/sftp-server -u 027 -f AUTH -l VERBOSE - OR - Subsystem sftp internal-sftp -u 027 -f AUTH -l INFO - OR - Subsystem sftp internal-sftp -u 027 -f AUTH -l VERBOSE Re-cycle the sshd daemon to pick up the configuration changes: # /usr/bin/stopsrc -s sshd; /usr/bin/sleep 5; /usr/bin/startsrc -s sshd
