Here are some changes to the LX's default setup that will make your life more easy.
I hate having the main app timeout and power down when. simply type:
to disable the main app on next start
You can also supply the name of an alternate main app like so:
echo /LF/djsm/djsm-start > /flags/main_app
Just note that /LF/Bulk isn't guaranteed to be mounted yet.
If your app isn't found, rcS will remove /flags/main_app to restore the default on the next boot.
This turns on telnet and ftp by default, and switches to a static IP address.
If you still want to have the automatic private ip:
And if you want a speedy boot (this eliminates a 6 second wait timer):
Removing USB-boot-mode auto-shutdown
When USB booting, the script /usr/bin/recovery runs. On line 8 of that script is an instruction to do a forced shutdown after 600 seconds.
To remove that annoyance, simply comment-out that line:
#( sleep 600; poweroff -f ) &
To remove the 2nd boot logo, comment out line 76 of /etc/init.d/rcS:
#imager /dev/layer0 /var/screens/LEGAL.png
To remove the startup sound, comment out line 91 of /etc/init.d/rcS:
#oss -w /var/sounds/startup.wav & # & tim end "sounds/startup.wav" &
SFTP and You
SFTP is one of the easiest ways to copy files over to your Explorer.
Configure your Explorer
Now that sshd is enabled to start on boot up automaticly we need to make a few changes to the sshd config
cd /etc/ssh vi sshd_config
Now uncomment the fallowing and change them to yes
PermitEmptyPasswords yes PermitRootLogin yes
Once done editing, hit the ESC key, then type :x to save and exit.
now you are ready to start sshd for the first time and generate a key, type:
This may take a minute or two for the key to be generated so sit back and relax.
To enable SSH and SFTP permanently, you will have to carefully modify /etc/init.d/rcS. Add the following line in the same location as the telnetd and vsftpd startup (~line 138), or optionally outside the check for /flags/developer (~line 136):
/etc/init.d/sshd start; ### tim done "sshd"
and optionally disable telnetd and vsftpd by adding a # before the first slash.
#/etc/init.d/telnetd start; ### tim done "telnetd" #/etc/init.d/vsftpd start; ### tim done "vsftpd"
Connect With your Linux Box
Right click your network icon thingy and configure your interface
Setting it to link only will prevent the Explorer from disconnecting randomly when you plug it in.
on your explorer run
to see what it's ip address is. Enter that address as the host in FileZilla and set the username as: root
Congrats you now have sftp access to your explorer :)
Using Explorer's Host Name
On Linux you may also use the Explorer's host name to access it, which will allow the Explorer to change its IP address, with out you having to change it in any of your program's profile settings. On bootup in the serial console the Explorer will show its host name, near the end of the bootup output it will be Explorer-<SERIAL NUMBER>. To use the host name you'll need to add .local to the end of it, so Explorer-<SERIAL NUMBER>.local will be the host name to use when accessing the Explorer.
New Kernel Copy
This may brick your Explorer and make it require a usb boot so only do this if your brave.
nandscrub -e /dev/mtd2 nandscrub /dev/mtd2 nandwrite /dev/mtd2 /usr/kernel.cbf
mtd2 is where the kernel is stored
