You have to use dropbearmulti from archive attached in this post to get scp working for telnet and SSH it is enough to locate in /mnt/etc/rc.sysinit these lines:

Code: Select all

echo "export PS1='# '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile

And change it to:

Code: Select all

echo "PS1='root@tv:\w \$ '" >> /mtd_rwarea/profile
echo -e "ENV=/dtv/.ashrc\nexport ENV\n" >> /mtd_rwarea/profile

ln -s /mnt/bin/ /dtv/bin

Than I have modified ./etc/init.d/01_01_catch_crap.init. I fixed the line with wrong path to mount.ko and added three more. Now it looks like this:

Code: Select all

    [ -e $MOD_DIR/kernel/drivers/pty/mount.ko ] && insmod $MOD_DIR/kernel/drivers/pty/mount.ko || echo "mount.ko not found."

    /bin/mount -o bind /mtd_rwarea/passwd /etc/passwd
    /bin/mount -o bind /mtd_rwarea/profile /etc/profile
    /bin/mount -o bind /mnt/bin/sh /bin/sh

Finally fix for telnetd (the same file) :

Code: Select all

    export HOME=/mnt/
    export PS1='root@tv:\w \$ '
    $SYSROOT/bin/busybox2 telnetd  -l /mnt/bin/sh

We need to change /bin/sh to /mnt/bin/sh (although at this moment it doesn't matter since we already mount-binded it ) and set up HOME and PS1 variables.

For scp we also needto change dropbearmulti to the one from the archive. Then we just make a symbolic link to dbclient:

Code: Select all

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

After this I have working bash history, telnet, ssh and scp

EDIT: Attached my /mnt/bin/busybox and dropbearmulti binaries.

    [ -e $MOD_DIR/kernel/drivers/pty/mount.ko ] && insmod $MOD_DIR/kernel/drivers/pty/mount.ko || echo "mount.ko not found."
