title: Pass rsh command password?
body: <p>Trying to log into a server with rsh, even though I usually log into it with ssh.  Works perfect with ssh, but I don't want to enter my password every single time.  </p>
  
  <p>I guess I need to pass the rsh command a password since I tried the following...</p>
  
  <pre><code>rsh -l user@servername 
  rsh -l user@servername -n
  rsh -l user@servername echo "something"
  </code></pre>
  
  <p>...but got this error message</p>
  
  <pre><code>rcmd: getaddrinfo: Temporary failure in name resolution
  </code></pre>
  
  <p>How would I log into rsh and either bypass my password (i.e. which I can't get rid of at the moment) or pass it my password?</p>
