Okay do you have now everything that I have described in this stoic:
  • SSH
  • SCP
  • bash history

I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on https://pastebin.com Otherwise "NO HELP"!!!

No just ssh with /bin/sh shell.
I tried to follow the guide for F8000 but without success.
Do I need something specific for F8000?

Thank you

I don't know if you "need something specific for F8000". I don't have ANY F :) You should check the E series tutorial!!! What did you do to make SSH work? Did you mount /mnt/bin/sh to /bin/sh?

Hi I have checked the tutorial but I am confused because 01_01_catch_crap.init is totally different for F and I can't find the part for mount.ko in any of my files.
For telnet I have separate file so I don't know what part where need to be included.
Please take a look over the attached files and point me what I need to do.

You can skip mount.ko it's not needed on your system. Just use the mount --bind commands..

It looks that 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/ash &  >> $LOGFILE 2>&1
add 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 \$ '
Finally get the dropbearmulti from E tutorial and put it in /mnt/opt/privateer/usr/sbin/. Then run this commands:

Code: Select all

chmod 755 /mnt/opt/privateer/usr/sbin/dropbearmulti 
ln -s /mnt/opt/privateer/usr/sbin/dropbearmulti /mnt/bin/dbclient
ln -s /mnt/opt/privateer/usr/sbin/dropbearmulti /mnt/bin/scp
ln -s /mnt/opt/privateer/usr/sbin/dropbearmulti /mnt/opt/privateer/usr/sbin/dropbear
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)

ln -s /mnt/opt/privateer/usr/sbin/dropbearmulti /mnt/opt/privateer/usr/sbin/dropbear

Code: Select all

/bin/mount -o bind "$SYSROOT/bin/sh" /bin/sh
export HOME=/mnt/
export PS1='root@tv:\w \$ '
This part was added to telnet script before start telnet command.

Finally I have access ftp and net cat access only - no ssh and telnet.

Code: Select all

lrwxrwxrwx    1 root     0               41 Jun 21  2014 dbclient -> /mnt/opt/privateer/usr/sbin/dropbearmulti
lrwxrwxrwx    1 root     0               41 Jun 21  2014 scp -> /mnt/opt/privateer/usr/sbin/dropbearmulti
My files are attached below.

Update:
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
