How To
Summary
Describes how to use Putty for SSH port forwarding with IBM i Access Client Solutions.
This could be applied to IBM i Access for Windows as well.
Objective
Environment
Steps
Please Note: IBM does not support PUTTY or configuring PUTTY.
Also, please note that if you have SSH available for your Windows OS or MAC OS Putty is not needed.
A section at the bottom will go over using SSH to port forward.
This is a working example.
Step 1) Install Putty on the PC, Putty is used for the SSH tunnel on windows.
Step 2) Configure Putty.
- Enter your systems IP Address.
- Make sure SSH is selected for connection type.
- Make sure the port is 22.
- Setup the tunneling in Putty.
- Select Connection > SSH > Tunnels.
- Add the Source Port then the destination.
- The following ports all need to be added: 23, 449, 8470, 8471, 8472, 8473, 8474, 8475 and 8476.
- It’s good practice for Telnet not to make the source port the same as the destination.
- In this example I choose 50000, you could use what ever as long as it’s not in use.
- Regarding the other ports, do not change the source port numbers.
The following screen shot is an example:
- The 50000 Port used is just an arbitrary port number. Use any available port you want between 49152 and 65535 (Dynamic Port range).
- After you press the Add button to add that forwarded port.
- Do this for each of the ports listed previously.
- Eventually you’ll have a populated list you can scroll through.
- Click back on session.
- Provide a name in the Saved Sessions box and press the save button.
- Then you will have the session save for future use and can just select the saved session and load it without having to go through the setup again.
- After you have loaded the saved session you can just press open.
- This starts a putty session to your system.
- You will be prompted to accept a key on the first use.
- Then your presented with a logon prompt.
- Use your IBM i session profile and password.
Step 3) Configure you ACS(Access Client Solutions) client or IBM I Access for Windows Client to use the SSH tunnel you just started.
- In both clients you go into Communications=>Configure.
ACS: PC5250:
- Change the IP address to 127.0.0.1 on port 23:
ACS:
PC5250:
- Press OK to save changes.
- Either client will restart and connect.
Your done!!
