To configure disk quotas for SFTP users, follow the below steps:
1. Enable quotas on your system by editing the “fstab” file and adding “usrquota” and “grpquota” to the mounted hard drive. For example:
/dev/sda1 /home ext4 defaults,usrquota,grpquota 0 2
1. Install the “quota” package on your system:
sudo apt-get install quota
1. Create a quota database file for each file system you want to monitor:
sudo quotacheck -cug /home
1. Turn on disk quotas on the file system:
sudo quotaon /home
1. Set the soft and hard quotas for each user:
sudo edquota -u username
1. Restart the SFTP server:
sudo service ssh restart
1. Test the quotas by logging in as a user and trying to upload a file that exceeds their quota limit. The system should deny the upload and inform the user of the limit.
Note: The above steps may vary depending on the Linux distribution you are using.
