dt-ssh-copy-id 0.1.0

Windows ssh-copy-id utility.

dt-ssh-copy-id

Command-line windows tool that loosely mimics the *nix ssh-copy-id command.

Purpose

ssh-copy-id installs (one or more) SSH keys on a target server as an authorized key. Its purpose is to provide access without requiring a password for each login.

This provides the ability to enable automated (passwordless) logins using the SSH protocol.

Features:

• Command line driven (loosely mimics the *nix syntax)
• Multiple target hosts can be setup via single run
• Identifies if keys are already present on target host(s).

Pre-requisites

• Python 3.10+ (may work with earlier version, not tested)
• fabric - layer over paramiko
• paramiko - facilitates SSH interactions with target servers
• loguru - manages logging

Setup

To install as a CLI (no source)

• pipx install dt-ssh-copy-id (creates a virtual environment)

or

• pip install dt-ssh-copy-id [--user]

To install source code

• git clone https://github.com/JavaWiz1/dt-ssh-copy-id.git

If you use Poetry, a virtual environment will be created with the required dependencies.

• poetry install

else, you may install manually with -

• pip install fabric loguru

Syntax

usage: ssh-copy-id [-h] [-f] [-i FILE] [-p PORT] hostname [hostname ...]

ssh-copy-id - copy ssh public keys to target host

positional arguments:
  hostname              [user@]hostname

options:
  -h, --help            show this help message and exit
  -f, --force           Force copy, no existence check.
  -i FILE, --identity_file FILE
                        the identity file to be copied. If not specified, adds all keys.
  -p PORT, --port PORT  SSH port (default 22)

Examples

• Install all public keys for user tom onto server1

  > ssh-copy-id tom@server1

• Install ONLY the rsa public key for user tom onto server1,2,3 and 4

  > ssh-copy-id -i ~/.ssh/id_rsa.pub tom@server1 tom@server2 tom@server3 tom@server4

• Install all public keys for configured (.ssh/config) user onto server 'rasberrypi'

  > ssh-copy-id raspberypi

---

NOTE:

• If you have a .ssh/config setup with defaults, those will be used (i.e. pre-defined usernames).
• You will be prompted for a password upon first login.
  • That password will be re-used for each server
  • If login fails for a server, you will be re-prompted to supply a valid password.
