Accesing #webOS Device via WiFi using SFTP Client

I'm using this because I'm tired of connecting USB cable everytime I want to copy files between my Palm Pre and my MacBookPro. Actually there's only 5 simple steps to follow:

  1. Install Preware
  2. Use Preware to install SFTP and terminal application
  3. Use terminal application to generate keys for OpenSSH
  4. Transfer SSH keys to desktop via USB
  5. Configure SFTP client (I'm using Cyberduck on Mac OS X) on desktop and connect
1. Install Preware
You can see here for complete reference

2. Using Preware to install SFTP and Terminal application
Still, you can refer to previous link for usage guide. FYI, I'm using SDL Terminal, other options is Terminal and Terminus

3. Use terminal application to generate keys for openSSH
I just did these steps:
# cd /
# /opt/bin/ssh-keygen (press Enter key once to accept default filename, then Enter key twice for blank password)
# mv /home/root/.ssh/ /home/root/.ssh/authorized_keys

Or you can read from wiki here

4. Transfer SSH keys to desktop via USB
First, run this command:
# mv /home/root/.ssh/id_rsa /media/internal/

Then connect your Pre to your desktop station via USB cable, and put it in Drive mode. Copy and save id_rsa file you've just copied to any safe place in your desktop station

5. Configure SFTP client on desktop and connect
First,you need to know your IP address on your Pre. Open Wifi and tap on current Wifi connection (SSID) to view the IP address.
Then, open your SFTP client. Since I'm using Cyberduck, for now I'm just explaining about how to use it on Cyberduck only. But, actually the steps are very similar on any SFTP client. 
1. Click on Open Connection
2. Choose SFTP (SSH File Transfer Protocol).
3. Fill in username: root
4. Leave the password blank
5. More options -> check "Use Public Key Autentication"
6. Click Connect

Just wait and see :D
