Overview
This is a production ready secure file transfer server built on OpenSSH, where every user is confined to a chroot jailed home directory with no shell. It provides managed file transfer without per user fees or storage vendor lock in.
Why the cloudimg image
cloudimg hardens the server with fail2ban brute force protection, per user disk quotas and transfer audit logging, and keeps user files on a dedicated, independently resizable volume. Accounts are managed with bundled one command tools for add, remove, list and password control, backed by 24/7 expert support.
Common uses
- Managed file transfer
- Partner data exchange
- Secure upload endpoints
