Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

login

user:root
pass:"" (blank, ENTER)

Maybe we can edit /etc/init.d so it stays without hdd?

Maybe possible make scroll.sh to usb key with telnet enable to /etc/init.d

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

sig 340 firmware can imstall mx on usb and start mx from usb. (insider info)

firmware update usb-top
usb -bottom for mx install

we need sig 340 firmware to see- what happening

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

Telnet Works great.

Some mounted filesystems read only.
Unsure about trying remount commands

I cannot get userfs.bin or rootfs.bin to dump properly.

ubuntu->

mkdir /media/userfs
mount -t cramfs -o loop /pathto/userfs.bin /media/userfs

Files show ok, and small (< 4Kb) extract fine. Files over 4KB look corrupted.
any idea?

I do not need to run MX from USB..

my suggestion was to build an upgrade file(scroll.sh) that edits /etc/init.d to enable telnet (is "system" filesystem always read only)
just like the hdd partioner you run before upgrade,
Enable telnet from DOK.

Files already play fine from USB and SMB, I do see why usb mx would be nice for all of you though. No hacking in a hdd!

Less fun!

из местных линуксоидов мне кто-нибудь обьяснит суть этого взлома?
человек - врубить телнет при помощи апгрейда с усб-диска?
а какие плюсы в использовании телнет без МХ?

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

Cannot dump userfs.bin, rootfs.bin properly
files > 4Kb look corrupt.

I want to rebuild firmware packages with customizations in filesystem, IE: /system/logo.jpg

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

To: nitrogen14
Cуть простая - отрубить винт от приставки, подключить к линуховому компу и поправить один файл.
Я сделал это проще - через свой scroll.sh. Проблема в том, что у меня телнет не стартует и ошибку не пишет.

To: Emerica
Thanks for the info, good to know it is possible. I managed to make the first step in even more elegant way without the removal of the HDD, using my custom scroll.sh. So now I have full read/write access to /etc, /boot, /tmp and hidden /.system directories. The directory /system (without dot in front) is read-only internal flash memory and so far I haven't found a way to re-mount it read/write. My problem is - whatever I do, telnet does not start. Editing /boot/config.ini.ext as you suggested doesn't help either. How would you start it from the init script (e.g. /etc/init.d/S25custom)?

**Emerica** · 20-10-2008, 00:17

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

Can you please post me your scroll.sh file so I can test with that?

I have not had much luck with scroll file for other things and do not have jtag yet, or know if box is putting out serial info, inittab looks like serial getty is commented out.
But might still prove to be active?

I think looking at it now i added the lines to makesettings ext not config.ini

you can remount some partitions ie:usb and hdd

mount -o remount,rw /path/

Cramfs is readonly filesystem so userfs.bin and rootfs.bin can be mounted under linux

mount --o loop -t cramfs /path/to/userfs/userfs.bin /mountpath/

I have been able to mount, but files over 4KB are corrupted, can anyone verify?
You can use mkcramfs to generate files but feel it's unsafe if the above is true.
Maybe custom cramfs is used or special options need to be passed.

you can also edit the samba conf to enable access to / and other dirs as well as make some of them writable.

**Emerica** · 20-10-2008, 00:23

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

I think if you know how to free up or add a loop device the you could copy userfs.bin to STB HDD and mount it there, then dump the files.
take the files as is back into mkcramfs and md5 the result.

I tried to do the above but no loop device were availiable
i tried to umount /system in hopes it might free up one, but I'm not a linux guru :/

**eugene777** · 13-11-2008, 21:16

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

To: Emerica
Sorry for keeping silence that long, didn't have a chance to properly setup my new Linux box.
Can't upload my scroll.sh yet as it is very experimental at this stage and requires several reboots with different commands to make it working. Eventually I will make it available.
Regarding your >4k files issue - yes, I confirm that they are corrupted.
But there is a reason behind, straight from the README of CRAMFS:
Currently, cramfs must be written and read with architectures of the
same endianness, and can be read only by kernels with PAGE_CACHE_SIZE
== 4096.
So far I didn't manage to find out how to adjust the kernel's PAGE_CACHE_SIZE. Pls let me know if you did.

**Emerica** · 14-11-2008, 05:29

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

Thanks for the reply, I have been busy with work so havent had too much time to work on the box.

The page cache limit is somthing i think the kernel has to be compiled with or possibly patched? I could be totally wrong.

I had a quick Idea, though I'm not sure if it would work and don't have a setup right now to test. Would mounting to or from a ramdrive with a blocksize of 4096 do the trick?

**eugene777** · 14-11-2008, 16:44

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

Unfortunately I was wrong as the default PAGE_CACHE_SIZE is 4096 (at lest on my PC) and this could not be the reason for the files corruption.

Must be something else...

**eugene777** · 16-11-2008, 20:47

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

To: Emerica
Finally managed to make telnet working. Your direct instructions did not work for my setup, but many thanks again for the info. It helped a lot. It seems that there is no problem to make telnet available via scroll.sh. It already works after a few steps, but I have to find out how to make it withing a single scroll.sh.

инструкцию по активации напишешь?

**eugene777** · 17-11-2008, 21:22

Re: Unlock Telnet on Sig-220 - HDD upgrade , usb possibly?

Ну, корневая директория смонтирована read-only. Ну вот собственно они все:

Код:

iSTB-22[/etc]# mount
/dev/mtdblock2 on / type cramfs (ro)
/proc on /proc type proc (rw)
ramfs on /tmp type ramfs (rw)
ramfs on /var type ramfs (rw)
/devfs on /devfs type devfs (rw)
/dev/mtdblock5 on /system type cramfs (ro)
/dev/mtdblock6 on /etc type jffs2 (rw)
/dev/hda1 on /tmp/.system type ext3 (ro)
/dev/hda2 on /tmp/.user type ext3 (rw)
/dev/hda3 on /tmp/hd type ext3 (rw)

Те, которые (ro) - read-only, /dev/hda1 можно перемонтировать rw.

А насчет инструкции по активации, я уже точно не помню, но попробовать можно.
Копируешь приэттаченный scroll.sh на usb stick, вставляешь и перезагружаешь. Все должно делаться в MX_Engline режиме.
Ждешь минуты 2-3 и пробуешь пингануть приставку. Если все хорошо:

Approximate round trip times in milli-seconds:

то можно идти дальше. При вытаскивании usb stick произойдет рестарт с правильным демонтированием всего, это лучше, чем отрубать питание. Редактируем scroll.sh и декомментируем эти 3 строчки:

Код:

#mkdir $MNT_PATH/media/Video/root/
#cd $MNT_PATH/media/Video/root/
#ln -s /etc/

, должно получится:

Код:

mkdir $MNT_PATH/media/Video/root/
cd $MNT_PATH/media/Video/root/
ln -s /etc/

Вставляешь usb stick и перезагружаешь.
Ждешь минуты 3-4 и вытаскиваешь usb stick. После загрузки приставки, с PC идешь в ее самбин Video фолдер. Там должен появиться фолдер root а в нем etc.
Если все появилось, открываем etc/init.d/S80startapp в каком-нибудь нормальном редакторе (например http://notepad-plus.sourceforge.net), добавляем 2 строчки в конце после $ETC_PATH/makesettings и перед exit 0. Конец файла должен выглядеть так:

Код:

$ETC_PATH/makesettings

sed -e &quot;s|@telnetd@|/usr/sbin/telnetd|g&quot; -i /tmp/inetd.conf
kill -SIGHUP `cat /var/run/inetd.pid`


exit 0

Крестимся и перезагружаем приставку.

Естественно, что никакой ответственности за вышеизложенное я не несу...
Тем более, что может я чего и забыл. Шансы убить приставку хоть и очень малы, но теоретически есть.
