2.6.1.1 SSH Daemon does not Start

Workaround to fix if the SSH daemon fails to start.

  1. View the c:\cygwin\var\log\sshd.log file for information on why the SSH daemon failed to start.
  2. Run the following commands to test SSH connectivity between the local node and the remove nodes. 
    ssh -l username localhost 'date'

ssh -l varname this node  'date'
    For example: 
    ssh -l pjohn node1.example.com 'date'

    This command prompts you to specify the password. When you specify the correct password, the command returns the accurate date.
