title: How do I check if a port is open between two Linux servers?
body: <p>How do you check if a port is open when you cannot use telnet or install Cacti?  I want to see if a port is open between two Linux servers.  Telnet isn't installed.  I tried this command: </p>
  
  <pre><code>cat &lt; /dev/tcp/x.x.x.x/6061
  </code></pre>
  
  <p>where x.x.x.x was the remote IP address of the Linux server and port 6061 is the port that I want to test.  But based on tests of known working and not working ports, this command wasn't conclusive to me.  There may be an environmental explanation for that. </p>
