Netclip

Self-contained pastebin for local networks, with no dependencies. Runs as a service on Windows too.

Why

I need to copy text between computers, and using a public pastebin isn't always an option. I need multiple computers to be able to paste things and see things pasted.

And once this is running it's quicker than transferring files.

Install

Download the binary for your OS.

Run

netclip

This runs the server on 0.0.0.0 port 9999. Override the port with -p 4000.

Run as a service

This supports running as a service on Windows, macOS, and Linux.

netclip -service install
netclip -service start

Stop the service with

netclip -service stop

Uninstall the service with

netclip -service uninstall

This works on Windows 7 and above, and Windows Server 2008 and up.

SSL support

Copying to the clipboard with JavaScript requires a secure connection. Run this behind a front-end with HTTPS and a reverse proxy or use self-signed certs.

Using self-signed certs

Generate self-signed cert that's good for a year.

openssl genrsa -out netclip.key 2048
openssl req -new -x509 -sha256 -key netclip.key -out netclip.crt -days 365

The first command generates a 2048-bit RSA private key and saves it to a file named netclip.key. The second command creates a new self-signed X.509 certificate called netclip.crt using the generated private key that's valid for 365 days.

Then create the file netclip.yml and give it the paths to those keys:

port: "4000"
cert_file: "netclip.crt"
key_file: "netclip.key"

These certs aren't signed by an authority so your browser will prevent you from using the site unless you allow it, which is only temporary.

Permanently add self-signed certs:

macOS (for Safari, Chrome, and Edge):

Double-click on the server.crt file to open it in the "Keychain Access" application.
Choose "System" or "login" under "Keychains" and click "Add."
If prompted, enter your macOS user password to confirm the action.
Find the imported certificate in the list, double-click on it, and expand the "Trust" section.
Set "Secure Sockets Layer (SSL)" to "Always Trust" and close the window.
If prompted, enter your macOS user password to confirm the action.
Restart your browser for the changes to take effect.

Windows (for Chrome and Edge):

Open the site using the self-signed certificate in Chrome or Edge. You'll see a warning message.
Click on the lock icon in the address bar, then click on "Certificate."
Go to the "Details" tab and click on "Copy to File" to start the Certificate Export Wizard.
Export the certificate using the default settings (DER encoded binary X.509).
Press Win + R, type certmgr.msc, and press Enter to open the Certificate Manager.
Go to "Trusted Root Certification Authorities" > "Certificates" and right-click on it.
Choose "All Tasks" > "Import" to start the Certificate Import Wizard.
Import the exported certificate file and complete the wizard.
Restart your browser for the changes to take effect.
