title: What does cifs_mount failed w/return code = -111 indicate?
body: <p><strong>Command:</strong></p>
  
  <p><code>sudo mount -t cifs //&lt;server&gt;/&lt;share&gt; -o username=user@domain,password=**** /mnt/&lt;mountpoint&gt;</code></p>
  
  <p><strong>error message:</strong></p>
  
  <p><code>Unable to find suitable address.</code></p>
  
  <p><strong>The syslog has:</strong></p>
  
  <p><code>CIFS VFS: Error connecting to socket. Aborting operation.
  CIFS VFS: cifs_mount failed w/return code = -111
  </code></p>
  
  <p>When I check out the documentation for mount via <code>man mount</code></p>
  
  <p>I see the following information about the error codes:</p>
  
  <pre><code>   RETURN CODES
     mount has the following return codes (the bits can be ORed):
  
     0      success
     1      incorrect invocation or permissions
     2      system error (out of memory, cannot fork, no more loop devices)
     4      internal mount bug
     8      user interrupt
     16     problems writing or locking /etc/mtab
     32     mount failure
     64     some mount succeeded
  </code></pre>
  
  <p>So does -111 mean the same thing as 1?  If so, how can you diagnose if it's permissions or the command isn't correct?  </p>
