Editing the read-only parts of an image

[Jeza67]

Ok...
Thx for tut...
I have one problem...
I want to implement OpenVPN in Gemini image.
I managed to do that on 500+ w.o. problem on Gemini 4.60
Now I want to do that on dm500.
Problem is that I need to put some libs in lib dir which is read-only.
libcrypto.so.0.9.7
liblzo.so.1
libssl.so.0.9.7
and tun.ko in /modules/net
When I put only liblzo.so.1 and tun.ko, everything is ok db reboots after flashing, but openvpn want start for some ssl problems.
I figure that problem is with two remaining libs libssl.so.0.9.7 and libcrypto.so.0.9.7 .
Then I try to put all 3 libs, flash it, but no joy...
Box do not want to reboot and blank screen.
Any suggestions?

Solved , work like charm!!!!

Hello i have followed the tut but black screen, i'm using ubuntu 9.10 desktop and mksquashfs from tuxbox-cvs
I have tried it on Gemini 4.2 and Gemini 4.7

Has anyone a vmware linux image with all the working utilites ?

any other ideas?

Thanks

Hi Guys

I too kept experiencing the blank screen issue after following the Devilfish Tut. I found that the problem was down to the wrong mksquashfs file. The one attatched works perfect for me. Put it on my Desktop (Ubuntu) along with the tuxbox-cvs & root directory. The ''./mksquashfs'' is a correct command. A big thanks to Devilfish for an excellent Tut.

Can this about method to edit the Read only parts be used for all dreambox's or is it only confined to the dm500 ?

Well - I'm trying to update my busybox on a image (peterPan / gemini etc) I've used for seperate commands in shell - like arp nohup etc.

But each time I reboot my dm500 - it just goes into blanckscreen and nothing happends.
I've tried squash the file - with ArchLinux,Debian and the special mksquashfs file earlier in the thread.

I got no errors etc - so what can I do to make it work - reflashing the image. Is it possible to update busybox in another way ????
outprint from more /proc/mtd

mtd6: 00120000 00020000 "DreamBOX Cramfs"

I've tried almost everything so what can I do - to upgraqde the busybox placed on the image!

For some reason my user name and password have changed on my dm800hd clone is there a way to get me back into the box without having to start again ftp comes back with a fault in the user name and password

hi
I know this is an old thread but its still very relevant. Thank you for the tutorials but i still seem to be having an issue with the blank screen after reboot. I know this seems to be an issue with the mksquhuashfs file and i have downloaded the file earlier in this post. When i try to run it i get denied although i think this has something to do withe the ttuxbox-cvs folder mentioned. I cant find this to put it on the desktop. Any chance someone could point me in the right direction.

Thanks
