Question : Problem: Need step by step to Tunnel to an Oracle DB using Putty

Hi to all.
I appreciate that you can provide me detailed instructions to perform the following:
From home, I use the SafeNet Secure VPN Client to access my work.
Once connected, I have to ssh to a box (let's call it 192.168.2.29), and once connected to that box, I have to ssh to another box that has the DB Server (192.168.1.28).
There is any way to use my LOCAL sqlplus on my PC to access directly to the DB Server using Putty Tunnel option?
So basically I'd like to access the DB Server directly from my PC (if possible).

Any help is appreciated

Answer : Problem: Need step by step to Tunnel to an Oracle DB using Putty

This are the steps that I performed:
- Open PuTTY and load your saved session.
- Choose Tunnels in the category section. Then in the "source port" section, put any port number that is not in use (example: 1234).
- In the destination text box enter the IP address of the host name (192.168.1.28 in my case) followed by a colon and the destination port number(1521).  Remember to click on the ADD button.
- Save your settings in PUTTY.
- Then modify your tnsnames.ora with something like this:
CCOM_PROD =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1234))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = CCOM)
    )
  )

- Then ssh to the 1st server
- Finally type the following to connect and create the tunnel to the second server:
ssh -L 1234:192.168.1.28:1521 [email protected]
