|
||||
| Timeout | Sets the connection timeout in milliseconds, default is 6000 ms. |
|
||||
| Connection Reuse | Sets whether SSH connections are reused, default is :false. If false, a new connection is created each time information is retrieved. |
|
||||
| Use Proxy Connection | Sets Whether connect via proxy, default is false. |
