Revision as of 20:55, 9 August 2009
You can use the USB Drive partition via WIFI as a non-root user by telling fstab to mount it owned by the non-root user's UID. This is useful if you don't want to have to remount the root partition, and if you don't want r/w access enabled for the entire filesystem when just transferring files...
Requirements
- Pre with SSH and SFTP installed, and connected to WIFI
- SFTP Client of some sort. (Nautilus, WinSCP, SSHFS, etc)
- You'll have to update your configuration if the IP of your Pre changes
//**Note: If the Pre is on battery, the SSH connection will lost when the display goes to sleep. Do this while the Pre is charging for best results.**//
Instructions
1. Login via SSH as the non-root user you created when you enabled [[[adding-the-ipkg-repository | the Optware Package Feed]]]. 2. Determine your uid (user id) and gid (group id)
id Example: gregnuj@castle:/var/home/gregnuj$ id uid=1001(gregnuj) gid=1001(gregnuj)
3. Edit /etc/fstab so /media/internal is mounted owned by your user id (group id recommended but not required)
sudo vi /etc/fstab
Modify the /media/internal entry as follows: (note: use the values obtained from the id command)
/dev/mapper/store-media /media/internal vfat uid=1001,gid=1001,utf8,shortname=mixed 0 0
4. Save the file by pressing <ESC>, followed by ":x" (w/o quotes) <ENTER>
5. Option 1: Reboot the Pre and you should now be able to read/write to the USB Drive partition (/media/internal) via SFTP using your non-root login.
OR instead of rebooting
Option 2:
cd /media sudo umount /media/internal sudo mount /media/internal
+++ Password-less Login (optional - for Linux or Mac)
1. Login to the Pre via SSH as your non-root user, and execute:
mkdir ~/.ssh
2. Generate a key pair on your host machine with:
ssh-keygen -t rsa
3. Copy ~/.ssh/id_rsa.pub on the host to ~/.ssh/authorized_keys on the Pre. 4. Test SSH/SFTP login from the host to the Pre to make sure you aren't asked for a password.
Possible Issues
- If the Pre is running on battery, it sleeps frequently, breaking the SFTP connection. This will cause file transfers to fail.
