[one-users] VNC problem: Failed to connect to server (code: 1006)

Mon Apr 29 10:11:47 PDT 2013

Hi People, Daniel Molina (dmolina at opennebula.org), and me Angel Miguel 
Hernandez (ahernandez at tesla.cujae.edu.cu), find the solution for problem 
with VNC. When you try open VNC of Virtual Machine, you obtain "Failed 
to connect to server (code:	1006)". The solution  for the problem is 
following the step of this web site:

http://t3chnot3s.blogspot.com.es/2012/03/how-to-enable-vnc-access-to-vms-on.html

1- Login to the vSphere host either at the console or remotely.
NOTE: On the console, this requires logging into the ALT+F2 screen as 
root or other admin with permissions, going to TROUBLESHOOTING OPTIONS, 
and enabling either ESXi Shell (console shell access) or SSH (remote 
shell access).

2- Change owner on firewall folder and services.xml file 
\etc\vmware\firewall\services.xml

I did the following (as this was my own lab in a protected 
environment):

     #CD /etc/vmware
     #CHOWN -R root firewall/
     #CHMOD 7777 firewall/

     NOTE: Use "ls -l" (lower case "L") to see permissions on the 
FIREWALL folder.

     Then…
     #CD firewall/
     #CHMOD 7777 service.xml

     NOTE: Use "ls -l" (lower case "L") to see permissions on 
SERVICE.XML file.

3- Edit the SERVICE.XML file to create a VNC service.
NOTE 1: Use VI or another text editor to add the below text at bottom 
of the file (assuming it is still in a default format).

NOTE 2: If you have modified your firewall then your service id may be 
different! This should be a sequential number which you can get from the 
previous listed service. By default it should be approximately "0032".

<!-- VNC -->
   <service id="0032">
     <id>VNC</id>
     <rule id='0000'>
         <direction>outbound</direction>
         <protocol>tcp</protocol>
         <porttype>dst</porttype>
         <port>
            <begin>5800</begin>
            <end>5999</end>
         </port>
      </rule>
      <rule id='0001'>
         <direction>inbound</direction>
         <protocol>tcp</protocol>
         <porttype>dst</porttype>
         <port>
            <begin>5800</begin>
            <end>5999</end>
         </port>
      </rule>
      <enabled>true</enabled>
      <required>false</required>
   </service>

NOTE 3: Use "i" (lower case) to insert text in VI.
NOTE 4: Use [ESC] to exit insert mode within VI.
NOTE 5: Use ":x" (i.e. colon then lower case "x") to save and write 
changes.
NOTE 6: You will notice in the above settings I am opening all ports 
between 5800 and 5999. You may not wish to do this!!

4- Save Services.xml file
NOTE: Any errors at this point will be file/folder permissions related.

5- Refresh firewall rules
esxcli network firewall refresh
esxcli network firewall ruleset list (for see the rules)

And the problem solved

Thank to all that colaborate in the solution!!!!!!!!!!, and I send a 
big thanks to Tino Vasquez.
