I have replaced busy box with the original one (that coming with the hack), and after reboot I have telnet but no ssh access.
Now my telnet prompt looks like this:
Code: Select all
Trying 192.168.0.101...
Connected to 192.168.0.101.
Escape character is '^]'.
root@tv:\w \$
Is my passwd file with correct format?
Code: Select all
root:$1$DEfAJ8Lp$cPsL2pjhMwzwjCoaC.Oxy.:0:0:SamyGO secured Root:$NEW_HOME:$SYSROOT/bin/ash
This prompt means you didn't correctly mount the /bin/sh. Besides you modify my lines!!! You have to do exactly what I say
Change the telnet line to:
Code: Select all
$SYSROOT/bin/busybox2 telnetd -p 23 -l $SYSROOT/bin/sh & >> $LOGFILE 2>&1
Sorry about that.
After the correction now my prompt looks better but I still not have access to ssh (password is not accepted):
Also oscam can't be started with this version of busy box with the default is fine. The Startup script is attached below.
Code: Select all
Trying 192.168.0.101...
Connected to 192.168.0.101.
Escape character is '^]'.
root@tv:/mnt #
Thank you for your assistance.

with this version of busy box with the default is fine.
What do you mean by that? I did not tell you to change anything with busy box... What did you do?

I have replaced the both files from here
viewtopic.php?f=40&t=7455#p56749
To have ssh access I have reverted my passwd like here:
The good news with the original busy box now I have ssh history
but I still no sftp access
Code: Select all
Status: Connecting to 192.168.0.101...
Response: fzSftp started
Command: open "root@192.168.0.101" 22
Command: Pass: ********
Status: Connected to 192.168.0.101
Error: Connection closed by server with exitcode 127
Error: Could not connect to server
The other thing is my root is starting much faster, before I needed to wait 30 secs.
I think with your fix now is better.

I didn't tell you to replace busy box, I didn't tell you to change your passed. Remove /mtd_rwarea/passwd, reboot TV and post the result of this command:

Can't be removed

root@tv:~ # rm -f /mtd_rwarea/passwd
rm: can't remove '/mtd_rwarea/passwd': Device or resource busy
The default password is like this:
Code: Select all
root:saJvQKUdIxRW2:0:0:SamyGO secured Root:/mnt:/bin/sh
About changed password you never told me that need to be the default. About busy box I wanted to test what is the behaviour with the ver for E.
Please keep in mind I am complaining from nothing just I want to help for improving SamyGO, and providing extra information from my side will help about this.
I am professional QA so believe me I know a lot about testing.

You can do whatever you want but don't ask for my help. I don't need any extra information. For now your "extra information" only makes it harder for me to help you. I need you to only do what I ask you to. Changing ssh password shouldn't have "big" impact on tests but it looks you have removed it completely!!! With that nothing will work!!!

Okay it looks that before we continue we need to make a fix to telnet init script. All the changes you have to do should go to the 01_02_telnet.init file.
Right before this line:
Code: Select all
$SYSROOT/bin/busybox2 telnetd -p 23 -l $SYSROOT/bin/sh & >> $LOGFILE 2>&1
change this:
Code: Select all
echo "export PS1='# '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile
echo "PS1='root@tv:\w \$ '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile
/bin/mount -o bind "$SYSROOT/bin/sh" /bin/sh
export HOME=/mnt/
export PS1='root@tv:\w \$ '
to this:
Code: Select all
echo "export PS1='root@tv:\w \$ '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile
echo "PS1='root@tv:\w \$ '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile
/bin/mount -o bind "$SYSROOT/bin/sh" /bin/sh
export HOME=/mnt/
export PS1='root@tv:\w \$ '
apply changes, reboot post the result of:
Finally the result of this:
Code: Select all
ls -l /mnt/opt/privateer/usr/sbin/drop*
