Once you have accessed Linux on your Pre, it would be nice to be able to get and put files off the Pre without having to switch to usb drive mode, and copy the files over,and switch back to user mode, and move the files out of the media/internal folder and so forth.
One good way to do this is via SFTP. If you are not sure what that is, please visit this wiki page.
This document assumes you know why you want sftp, and how to use it once it's on the Pre.
Step 2: Set Read/Write Access:
1 sudo -i mount -o remount,rw /
Step 3: Install the needed components from ipkg-opt:
cd /opt/bin ipkg-opt update ipkg-opt install openssh-sftp-server
Step 4: Modify the sudoers file to allow your user account to sudo sftp-server without a password:
Once in the file, add the following line after the existing ALL line for your user - where //myusername// should be replaced with the user account that you are using to access your Pre via SSH. The order of the lines count here :
myusername ALL=(ALL) ALL myusername ALL=NOPASSWD: /opt/libexec/sftp-server
Quit and save your changes (ESC :wq)
Step 5: Mount the Pre's file system as read-only:
mount -o remount,ro /
Step 6: Reboot via one of the methods below:
sudo su -l reboot
Method 3: Turn off the Pre by holding the power button until the 'Turn Off' button appears and then pressing it. Turn the Pre back on after it has turned off by holding the power button until you see the Palm logo.
Other Methods: You may be able to reboot the phone with other commands. You can hit Orange+Sym+R on your Pre's keyboard to perform a soft reset, as well.
To login to the Pre using WinSCP:
Hostname: [my pre's ip] port: [my pre's port] (222 if you followed the Optware enabling instructions verbatim) username and password you set Check 'Advanced Options' and select "Environment>SFTP". In the SFTP server box enter: sudo /opt/libexec/sftp-server Be sure to set "mount -o remount,rw /" to write and "mount -o remount,ro /" when done. (If on Windows, do this through PuTTY. I haven't found a way to do it through WinSCP, but you can go to "Commands>Open in PuTTY" from the main toolbar.)
