# ISOSilo
|
|
|
|
A lightweight Go web server that lets you browse and download files from ISO 9660 images via your browser — without mounting them.
|
|
|
|
## Features
|
|
|
|
- **Library view** — lists all `.iso` files in a directory as clickable cards
|
|
- **In-ISO browsing** — navigate directories inside any ISO just like a file manager
|
|
- **File downloads** — download individual files directly from within an ISO
|
|
- **Clean UI** — dark-themed, responsive interface with file-type icons
|
|
- **Safe** — path traversal protection; only `.iso` files in the served directory are accessible
|
|
- **Zero mount required** — reads ISO images directly using the ISO 9660 library
|
|
|
|

|
|
|
|
```bash
|
|
# Serve ISOs from the current directory on port 8080
|
|
./isosilo
|
|
|
|
# Serve a specific directory on a custom port
|
|
./isosilo -dir /mnt/isos -addr :9000

|
## Security Notes
|
|
|
|
- The server only serves files with a `.iso` extension from the configured directory.
|
|
- ISO names are validated to prevent path traversal (`..`, `/`, `\`).
|
|
- Internal ISO paths are cleaned before use.
|
|
- There is **no authentication**. Do not expose this server to the public internet without adding auth (e.g. a reverse proxy with basic auth).
