Firewall Cause Oracle Listeners Can Not be connected.

for some reason, when I type tnsping in cmd.exe    it says  "no listener"
but the services.msc has a service "OracleOraDb11g_home1TNSListener"   it is started.

1. what I did is remove: the listener using "Net Configuration Assistant" to remove listener.
2. Then "REMOVE" c:\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
remove listner.ora file.
3.   Stop the Windows Server 2008 R2 firewall setting.
    I think this is the problem, the firewall causing the problem.

4.  Finally Add New listener again!!
then it worked.

the differences are in the file below it uses hostname instead of ip address.

How To Access Windows Host Folders From Redhat Linux Guest in Oracle VirtualBox

After you install a new virtual machine and install a guest operating system, how do you access files/folders from your host from guest? There are two basic approaches, ftp or folder sharing. Here is to address the folder sharing approach.
 
This guide is for the following environment:

• Windows 7 Host Platform
• Oracle VirtualBox 4.1.7
• Red Hat Enterprise Linux 5.8 Server (x86) Guest Platform   

You just need to follow the three steps:

1. Set shared folder
From the VirtualBox menu  click Devices->Shared Folders ...

2. Install Guest Additions
From the VirtualBox menu  click Devices->Install Guest Additions ...

3. Mount windows shared folders in Red Hat Linux
    3.1 Create a mount point using the following command
          sudo mkdir /mnt/shared-folder
    3.2 Mount the shared folders using the following command
          sudo mount -t vboxsf shared-folder /mnt/shared-folder

Note: If you work on the VMware, you still need three steps. to mount windows shared folders, do the command:
          sudo mount -t vmhgfs .host:/Share /mnt/share
