Fixing SamyGO telnet/SSH/SCP/bash on C/D/E/F series

[gogo]

Why this command don't work?

umount /mtd_rwarea/passwd
umount: can't umount /mtd_rwarea/passwd: Invalid argument

because you are not using latest stuff As a result your /mtd_rwarea/passwd is not mounted. You can check it by running:

Code: Select all

mount

This is then unnecessary.
It is enough only:
rm /mtd_rwarea/passwd

I didn't really find out what should we do for D series.
Coud you please help?
Thanks

Hello sectroyer,

what of the "new stuff" is enough to get /mtd_rware/passwd mounted?
I did all of the lines in your post about F series, and still with mount command I can't see it mounted.
Telnet, FTP works but with SSH I get authentication failed.

Command:
$SYSROOT/bin/busybox mount | grep "etc" gives

/dev/mmcblk0p16 on /etc/profile type emmcfs (rw,relatime)
/dev/mmcblk0p16 on /etc/passwd type emmcfs (rw,relatime)
/dev/mmcblk0p16 on /etc/profile type emmcfs (rw,relatime)
/dev/mmcblk0p16 on /etc/passwd type emmcfs (rw,relatime)

Use new rooting method. Than passwd IS mounted

[miksi]

So I can root my F6510 model fw1119 also with the new root method (for fw>=1120)? Ok. Thanks. I will try it soon.

[zoelechat]

So I can root my F6510 model fw1119 also with the new root method (for fw>=1120)?

Confirmed

[miksi]

And then I will have Skype functional again. Minus one flash stick "permanently" attached.
Again, thanks for great effort and sharing knowledge. This things are sometimes mind bogling because one needs to pay attention to many things simultaneously. Cheers.

[miksi]

And now I can confirm, new root method for "old" firmwares works, telnet, SSH, SCP all works as it should for F6510. I have occasional TV restarts but that's nothing new.
I want to try recording on NFS shares (on my PC) again. I did it once before but I forgot exact procedure. It will come up eventually. Regards.

I wanted to make as little changes to original SamyGO files as possible. Therefore (whenever it was possible) I have put most of my code in seperate files (rcEXT, rc.fix_telnetd, etc.). However probably it could be simplified and integrated directly with existing files (/dtv/.ashrc or /dtv/SGO.env). In order to make telnet working correctly (full bash history across reconnects and restarts, no more need to type . /dtv/SGO.env to have everything set up). You have to create following files:

$SYSROOT/rcEXT:

Code: Select all

#!/bin/sh

source /dtv/SGO.env

#echo "alias sgopwd='cd $1'" >> /dtv/SGO.env

echo "#!/dtv/network_opt/sh" > /dtv/sgoshfix
echo ". /dtv/SGO.env" >> /dtv/sgoshfix
echo "export HOME=\"$1\"" >> /dtv/sgoshfix
echo "export TERMINFO='$1/etc/terminfo'" >> /dtv/sgoshfix
echo "export TERM='xterm-color'" >> /dtv/sgoshfix
echo "export FRAMEBUFFER='/dev/sam/fb0'" >> /dtv/sgoshfix
echo "export LD_LIBRARY_PATH=\"$LD_LIBRARY_PATH\"" >> /dtv/sgoshfix
echo "export PATH=\"$PATH\"" >> /dtv/sgoshfix
echo "export SYSROOT=\"$SYSROOT\"" >> /dtv/sgoshfix
echo "export PS1='\u@tv:\w \\$ '" >> /dtv/sgoshfix

chmod +x /dtv/sgoshfix

ln -s "$SYSROOT/opt/privateer/usr/bin/" /dtv/bin

$1/etc/rc.fix_telnetd&

$SYSROOT/etc/rc.fix_telnetd:

Code: Select all

#!/bin/sh
killall telnetd
. /dtv/sgoshfix
cd
telnetd -l /dtv/network_opt/sh

In some cases you may have to run:

Code: Select all

chmod +x $SYSROOT/rcEXT
chmod +x $SYSROOT/etc/rc.fix_telnetd

Finally add to the end of $SYSROOT/rcSGO this single line:

Code: Select all

$1/rcEXT "$1"

After this you will have "fixed" telnet working. In order to "fix" SSH you just have to change the file $SYSROOT/etc/rc.sysinit. Locate the line:

Code: Select all

echo "export PS1='# '" >> /mtd_rwarea/profile

Comment it out and put bellow these lines:

Code: Select all

echo "PS1='\u@tv:\w \# '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile
echo ". /dtv/sgoshfix" >> /mtd_rwarea/profile
 
mount -o bind /dtv/network_opt/sh /bin/sh 

Now both telnet and SSH have colors, full bash history across reconnects/reboots and always start a shell in $SYSROOT directory.

To get SCP working we just need to copy patched dropbear binary (attached in archive) to:

Code: Select all

$SYSROOT/opt/privateer/usr/sbin/dropbear

and scp static binary to:

Code: Select all

/opt/privateer/usr/bin/scp

hi sectroyer i try to fix telnet and ssh with this i copy samygoscp to my samygo directory but it seems don't work
when i connect to telnet with putty there are no colors and no history.
my tv is c series
