cupholder

Local or remote CD tray ejection, for Linux.

cupholder can be useful:

• If you have a large server room with many computers with CD trays, this can be used for finding a specific server.
• If you need an example for how to call ioctls from Go without using C (https://github.com/xyproto/cdrom/blob/main/cd.go).

Usage

cupholder

Or when building a project that takes a while, as a notification utility:

<build command>; cupholder

For specifying a specific device:

cupholder /dev/cdrom

All arguments are treated as device filenames.

Use -s for silent operation and set the NO_COLOR environment variable to disable colors.

Web server

cupholder includes a web server that can be launched with the -l or --listen flag, that lets you eject the CD remotely, just by visiting the HTTP page at port 3280 (3280 = 0x0CD0).

For ejecting the tray using curl, a command like this can then be used:

curl --silent --output /dev/null --write-out '%{http_code}\n' http://localhost:3280/

Replace localhost with the hostname or IP address of the server where cupholder -l is running.
