If you guys are still interested I'd be willing to write a tutorial/blog on how to do it.
Nightowl login update#
None of the images use any sort of update signing.so even if they did try to patch this method and just get rid of the telnet server, it would be possible to still put it back via a patched update. This is super easy for the DVR's that use a tar.gz update, but the ones that do a full jffs/yaffs2 flash are a bit trickier I imagine, but its surely not impossible, I just don't have one to test and come up with a proper procedure on how to do it. I did however get into the telnet server, basically to cut a long story short, you need to just make an update file that sends a new /etc/passwd with your own MD5 hash as the root password and then boom, you're in. I got my hands on a Zmodo DVR that also had UART console blocked, I'm guessing they've done it at the kernel level because I can't seem to get it enabled by any means.

I think this board is a cool little specimen to mess around with embedded linux and maybe I can do something about the crappy web front end that requires ActiveX, but at a minimum, shell access to make backups of video vs. He mentions this site, but I'm not quite certain what to look for: Where did you get the TTL-to-USB adapter you're using? I have been following the advice in this guide as I am a software guy and have little experience in embedded systems: I just got through taking the board out to see if I could identify the processor and come across pinouts to trace to the UART leads and can't seem to find any info on it, but it looks like my Zmodo board is very similar to the one you show.

I'm trying to get a login to my Zmodo box and stumbled across this post after hammering away at the telnet login with Hydra for quite a while. You might need to check those two lines for different boxes, if you issue the command printenv you'll see the bootargs and the boot address.įrom here you can either call passwd to change the password, or if you want to retain the old one you can copy passwd to passwd~ and rename passwd- to passwd which will leave you with the weak broken password "helpme"
