[kepler-users] new user issue with sshexecutecmd

[Jianwu Wang]

  Hi Mark,

       Usually the channel index error is not actor related. It could be 
some error in workflow.

      Which Kepler version you are using? I can send you a demo workflow 
to deploy jobs to remote machine. I think SSH Execute cmd actor is not 
the only option. Or I can have a look at your workflow if you want.

Best wishes

Sincerely yours
