Resxtop not working in vSphere 5.1?

If you notice that resxtop fails when executed from the vma in vsphere 5.1, perform the following steps.

Task 1 – Create a new certificate for your ESXi hosts

1. Download the from and save it to your Desktop.

2. Use tools like winscp to transfer the script to your vMA virtual machine and save it to the home directory of vi-admin:

   1. From the Desktop system, install and launch winscp

   2. Enter the vMA host name and user and password (ex: vma, vi-admin, vmware1!).

   3. Click Login

   4. In the left panel, browse to your local desktop.

   5. Drag and drop the script from the left panel to the right panel. Choose “Copy” when prompted.

3. Log in to your vMA using putty. Create a file, listServers, which contains your ESXi host names:

1. At the command line type in the following:
cat > listServers <<EOF

4. Generate new certificates for your ESXi hosts:

   1. Make the script executable
   chmod 555

   2. Execute the script
   ./ listServers

5. Now copy the two new certificates to your ESXi hosts:
scp ssl-certs/esxi01/rui* root@esxi01.vclass.local:/etc/vmware/ssl
scp ssl-certs/esxi02/rui* root@esxi02.vclass.local:/etc/vmware/ssl

6. Restart the rhttpproxy service on both ESXi hosts:
ssh root@esxi01.vclass.local “/etc/init.d/rhttpproxy restart”
ssh root@esxi02.vclass.local “/etc/init.d/rhttpproxy restart”

7. After restarting the service, your hosts will disconnect from vCenter. Login to the vSphere
client and right click on the hosts and select “Connect”. The connect will fail with a digital
certificate verification error but you will get prompted to enter the root password. Go ahead and
accept the new certificate. Accept the defaults on all other screens and reconnect your hosts.

1. If your host has not automatically disconnected, disconnect it now.
2. Right click on your host and select Connect. Click Yes when prompted to reconnect.
3. Click Close when you get the error about the SSL certificate verification failure.
4. When prompted, enter the root user and password for your ESXi host.
5. Accept the new certificate.
6. Accept all the defaults on the remaining steps and click Finish.

8. Update the vMA environment to use the new keys.

   1. First make a backup of the .bashrc file:
   cp .bashrc .bashrc.bak

   2. Next, append two lines to the .bashrc file:
   cat >> .bashrc << EOF
   export HTTPS_CA_DIR=/home/vi-admin/ssl-certs
   export HTTPS_CA_FILE=/home/vi-admin/ssl-certs/cacert.pem

   3. Now reload the current shell environment
   . .bashrc

9. Test your setup
vifptarget -s esxi01

How to install Vshield Manager 5.1.2

Configuring Vshield Manager 5.1.2

Step 1: Download the Vshield Manager ova from

Step 2: Burn it into a dvd (optional).

Step 3: Launch the vsphere client and connect to the vcenter server or esxi server.

Step 4: Click on file and deploy from ovf/ova. This linux-based appliance defaults to 2 vcpus and 8 gbs of ram. This appliance has 3gbs of ram reserved. The virtual disk uses 60gbs of space.

Step 4: Boot up the appliance. This appliance defaults to dhcp and has one virtual nic connected to the port group called VM Network.

Step 5: Open the virtual console of the appliance and log in as admin with the password "default".

Step 6: Configure its networking settings by entering enabled mode. Simply type "enable" and provide the appliance's default password (default).

Step 7: Run the "setup" command to modify its networking settings. After running this command, you need to provide an ip address, netmask, gateway ip and dns domain info. Once you enter the information, answer "yes" to save the settings.

Step 8: Type "exit" to log out of enabled mode. Feel free to log in with the same name and password in order to run the ping command and test connectivity.

Step 9: Launch your browser and connect to the ip address of the vshield appliance. Log in as admin/default.

Step 10: Click on "Edit" next to the vcenter server to specify who is the vcenter server. You also have the choice to edit the ntp settings, syslog collector settings and SSO lookup service. In the upper right corner, click on Change Password and modify the default password.
