Hi is possible to modify the file usb_cmd created in mtd_rwarea from link0 after the hack?
can i simply re-edit it with notepad++ and reboot tv to apply changes or i lost my hack?I have done hack and i've full access to my tv run.sh is executed from usb.
i want to modify my usb_cmd according to here viewtopic.php?f=13&t=1076#p9426

Do not ever edit scripts with notepad.

I`m not vell with that hack, but i think everything should work after modiffication. If not, you always can re-hack

i try but the results was that tv can't recognize the usb connected to tv so i've to rehack.
i don't understand if the error is due to the wrong usb_cmd maybe i've to ask @mamaich but it's no longer on samygo forum.
juuso do you know how to create a init script for telnet? i'm thinking to start the telnet daemon from busybox present in SamyGO/bin directory but i've no idea in how to do it.

so as far as i understand you want to have the modified version of usb_cmd to have telnet enabled?
do you plan on using SamyGO-Extensions? If yes you get a ssh-daemon with it which is more comfortable than telnet.
as you still want to look for a run.sh file on your usb-drive, why don't you put the telnet part of mamaich's script into your run.sh on usb-drive this way the risk of breaking something is way smaller

i want telnet because is more simple to use for me instead of ssh, telnet don't need login every time i launch it.
i stilll have the run.sh that launch telnet and ftp after tv poweron.
my goal was to create one step usb hack.

take telnet script from any other series and adapt for your needs. Example:

Code: Select all

#!/mnt/bin/busybox sh
#
# ? Copyright 1996-2013, SamyGO
#
#
. /dtv/SGO.env

stop_bootloop()
{
# emergency skript exit to prevent boot loop
      for USB in ${1:- \
         /dtv/usb/sd* } ; do
         echo "checking $USB"
         sleep 1
         if [ -e $USB/STOP_TELNET ]; then
            "STOP_TELNET found. Script exit..."
            exit 1
         fi
      done
}

case $1 in 
	start)
	stop_bootloop # in testing phase. Just for protection.

	# telnet
	$SYSROOT/bin/busybox2 telnetd -p 23 -l $SYSROOT/bin/ash &
	sync

	;;
	stop)
	;;
	status)
	;;
	*)
	echo "Usage: $0 {start|stop|status}" 1>&2
	exit 0
	;;
