Unable to integrate Putty using SSH Connection

Help Activities

Hi Forum,

I was trying to integrate putty using UiPathTeam.SSHConnector.activities, I have passed all the values in SSH Connector Scope except passprase key for that particular private key as i don’t find the option in the properties.

Could anyone suggest how i can make the option enabled, as i don’t have good knowledge on C# to overwrite the source code,

Also please suggest any other way for putty integration if possible.

1. Verify the Package Version

Ensure you are using the latest version of the UiPathTeam.SSHConnector.activities package. Developers may have addressed the issue in recent updates.

  • Open Manage Packages in UiPath Studio.
  • Check for updates to the UiPathTeam.SSHConnector.activities package.

2. Use OpenSSH with Command Line

You can use the plink or ssh command-line utilities instead of the SSH Connector activities. These utilities allow you to specify a private key and passphrase.

  1. Generate the Required Command:

bash

Copy code

ssh -i /path/to/private/key -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no username@hostname

Adjust the path and options as needed.
2. Integrate with UiPath:

  • Use the Invoke PowerShell or Start Process activity in UiPath to run the SSH commands.

3. Custom Script with a Third-Party Library

If you’re open to scripting:

  • Use Python with libraries like paramiko.
  • Write a script to handle SSH connections and passphrase management.
  • Call the script from UiPath using the Python Scope or Invoke Code activities.

Example in Python (using paramiko):

python

Copy code

import paramiko

def connect_with_passphrase(host, port, username, private_key_path, passphrase):
    key = paramiko.RSAKey.from_private_key_file(private_key_path, password=passphrase)
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(hostname=host, port=port, username=username, pkey=key)
    stdin, stdout, stderr = client.exec_command('ls')
    print(stdout.read().decode())
    client.close()

Pass the necessary parameters from UiPath to the script.

4. Consider Alternative SSH Libraries

If you need a more comprehensive solution:

  • Use the Renci.SshNet library in a custom C# implementation. Although you mentioned limited C# knowledge, this approach may provide full control over SSH features.
  • Hire a developer or collaborate with someone to create a reusable library activity.
