I open a SSH connection with a name like:

SSHLinux\_%ServerName%

Then, I perform a SSH Execute, and it fails with:

SSH Connection not found: SSHLinux\_%ServerName%

Or:

&nbsp;

An unexpected error occured : System.NullReferenceException: Object reference not set to an instance of an object.

&nbsp; &nbsp;at VSoft.FinalBuilder.SSH.InteractiveClient.Send(String command)

&nbsp; &nbsp;at VSoft.FinalBuilder.SSH.ActionExecuteCommand.OnExecute()

&nbsp; &nbsp;at VSoft.FinalBuilder.SSH.ActionBase.Execute()

&nbsp; &nbsp;at VSoft.CustomActionApi.BaseAction.ExecuteWrapper(ICustomActionExecuteContext Context, ExecuteDelegate Target)

&nbsp;

SSH Close fails with:

"The connection is not open"

&nbsp;

I suspect, but can't confirm, that either SSH Open or SSH Execute/Close aren't "unwinding" the variable values. &nbsp;I would expect SSH Open to create a connection with a name like "SSHLinux\_daphne\_qa" and the later SSH connections use this connection. &nbsp;We're using asynchronous action groups to perform SSH against multiple machines simultaneously from within the same action list. &nbsp;So, each action list has it's own "ServerName" variable. &nbsp;

BTW, this connection naming pattern seems to work fine for the SFTP actions.

See example project, you'll need to set username/password/server1/2 to some appropriate values for your environment. &nbsp;Thanks for any help!

Hi John   
  
 This is a bug, the ssh execute action was not expanding variables. I’m running a build with the fix included right now, I’ll post here when it’s uploaded.
