SSH Client

Opens a SSH connection with a third-party Ethernet device for as long as the input is high.

SIMPL+ Wrapper that wraps SSH Client DGI DotNetSshClient

Creates a SIMPL SSH Client with the following attributes:

• IP addresses and ports can be assigned either as a Join Signals or as Parameters, which avoids having to create IP tables.
• Joins allow to change of addresses, ports, username of password during runtime. The underlying C# driver will automatically disconnect and reconnect whenever the IP address, Hostname, Port, Username or Password are changed
• As long as the Connect signal is High the driver will try to connect, even if no remote device connects, or if a device connected, and the dropped its connection. Time between retries will increase with each unsuccessful connection to not overburden the network or the processor.
• Failures are not logged in the Logger. To see results in real time check status of symbol.
• Adds Serilog to log events. Log Levels can be set from Verbose to Error. Default is Error.
• Logs will be written to console when the program runs in an Appliance and to Error Log when running on a server.
• v1.1.0 supports resolving mDNS names
• Sent Data to SIMPL is limited to chunks of 250 characters, to work about SIMPL's serial join character limitation.

Notes

As its Acronym implies SSH is a Secure Shell implementation. Therefore this driver is assuming that it will be sending commands to the device as if it was a Shell, ie, human readable one line commands terminated by a Return.

Therefore when interfacing with this driver there is no need to append a new line or return character, since a single send message will be interpreted as a one line command. (It will work just fine if the character is inserted though)

This driver does not implement file transfer or anything else that are not one line commands.
