Hi, i am new to pipelines and able to generate ssh key pair under pipelines setting and also added to my remote host. Luckily when adding host name and by clicking on fetch is also working and i m seeing fingerprint 
Steps followed from this link

The question is does above steps enough to execute ssh instruction to my remote host or am i missing something.
For instance i m trying to run following script under pipelines steps but getting timeout error:
ssh user@remotehost "pwd"

This suppose to give me present working directory of remote host but getting connection timeout error. Any help would be appreciated?
