jumpstarter-driver-ssh-mitm 0.8.1

SSH Man-in-the-Middle driver for Jumpstarter that securely stores SSH keys on the server and proxies connections

SSH MITM Driver

jumpstarter-driver-ssh-mitm provides a secure SSH proxy layer where private keys are stored on the exporter and never transmitted to clients. It is designed to be used as a child of SSHWrapper.

Installation

:substitutions:
$ pip3 install --extra-index-url {{index_url}} jumpstarter-driver-ssh-mitm

Architecture

SSHWrapper --> SSHMITM --> TcpNetwork --> DUT

• SSHWrapper: Handles SSH CLI and command execution
• SSHMITM: Provides authenticated proxy connection (stores the SSH key)
• TcpNetwork: Raw TCP connection to the DUT

Configuration

The command name is determined by the key in the export section. Use ssh_mitm to get the j ssh_mitm command:

export:
  ssh_mitm:  # ← This gives you "j ssh_mitm" command
    type: jumpstarter_driver_ssh.driver.SSHWrapper
    config:
      default_username: root
    children:
      tcp:
        type: jumpstarter_driver_ssh_mitm.driver.SSHMITM
        config:
          ssh_identity_file: /path/to/private/key
          default_username: root
        children:
          tcp:
            type: jumpstarter_driver_network.driver.TcpNetwork
            config:
              host: 192.168.1.100
              port: 22

Or with inline key:

export:
  ssh_mitm:  # ← This gives you "j ssh_mitm" command
    type: jumpstarter_driver_ssh.driver.SSHWrapper
    config:
      default_username: root
    children:
      tcp:
        type: jumpstarter_driver_ssh_mitm.driver.SSHMITM
        config:
          default_username: root
          ssh_identity: |
            -----BEGIN OPENSSH PRIVATE KEY-----
            ...
            -----END OPENSSH PRIVATE KEY-----
        children:
          tcp:
            type: jumpstarter_driver_network.driver.TcpNetwork
            config:
              host: 192.168.1.100
              port: 22

SSHMITM Config parameters

Parameter	Description	Type	Required	Default
default_username	SSH username for DUT connection	str	no	""
ssh_identity	SSH private key content (inline)	str	no*	None
ssh_identity_file	Path to SSH private key file	str	no*	None

* Either ssh_identity or ssh_identity_file must be provided.

Required children

• tcp: A TcpNetwork driver providing target host and port

Usage

Since SSHMITM is used as a child of SSHWrapper, you use the configured command name (e.g., ssh_mitm):

# Execute a command
j ssh_mitm whoami

# Interactive shell
j ssh_mitm

# With arguments
j ssh_mitm ls -la /tmp

# With SSH flags
j ssh_mitm -v hostname

Note: The command name (ssh_mitm) is determined by the key in your exporter config's export section. You can use any name you prefer.
