Cloud Commander, a web based file manager with a built in editor, secured with per instance login.
Cloud Commander is an open source, web based file manager with the classic two panel layout and a built in text editor. Browse, edit, upload, download, rename, copy, move and pack files on a server from any browser, without exposing SSH or a remote desktop.
cloudimg delivers Cloud Commander hardened and fully patched, served over TLS with a self signed certificate regenerated on first boot. Authentication is on by default and a unique admin credential is generated per instance, with only the one way hash stored in the server config. The service binds to loopback behind an nginx reverse proxy, and the built in terminal and console are disabled to keep the attack surface minimal. Backed by 24/7 support.
