I wish we could get all of the people interested in this project online at the same time.

I keep seeing that the CIC Root directory files are Read-Only.
I'm not sure about QNX in particular but under any standard UNIX you can start by checking 3 things:

1) is the filesystem mounted RW ? check with "mount" command or looking into /proc/mounts or similar
2) are you root or any other user allowed to write to those files ? check with "stat" command or "ls -l"
3) are the files marked with the write bit ? again check with same commands as in (2)

regarding the root password, I have already read in a few places around the internet at least two different passwords for CIC's root user. So I guess it's already cracked ?

by the way, by what means are you getting inside the CIC file system ? telnet, ftp or autorun ?

I'm not, yet....
I have a desktop and web application background but new to this kind of platform.
I've been lurking around the internet researching on and off the last few months trying to learn how to do this.
I just don't like asking questions to things that have been answered a million times so until I get to a question that I can't find an answer to I trek on in the background learning.

I first looked into this a few years ago and contacted QNX to get a trial version, but that only lasted 30 days. Wasn't really enough time for a noob to pick stuff apart, but I was at lease able to download all of the manuals which usually require a serial to download. Posted those here by the way, I'm sure you saw them. After the trial ended I got busy for a few years and this went to the backburner.

Anyway, I have more free time now and plenty of ideas for custom apps and menu hacking so I'm starting to invest more time into it again.

I did try to install the QNX environment for the thread here on SpoolStreet, but I'm confused about some of the steps.
I'll try again soon to get that up and running. If I can't get it again I'll post my questions on that thread and hopefully you or another knowledgeable enthusiast will help get me roll'n.

BTW, right back at cha, by what means are you getting inside the CIC file system?

I'm confused then. How can you tell the root filesystem is marked read-only ?

Nice, I don't have much free time but I am in the same mood of starting playing with the CIC.

I am versed in UNIX but I am pretty new to CIC as well. I was a F30 guy, just got an E90 a week ago. And it has been getting some love in the detail shop for the last week so for now I am just doing some reading.

BTW, right back at cha, by what means are you getting inside the CIC file system?
I played with autorun for 5 minutes and that was it. It was enough for a filesystem dump so I know what to expect when the real action starts. This week I bought my ENET cable so I should be ready to start playing with telnet when this cable arrives (not expecting it to arrive this year though... it was shipped from china).

You can count on me, we are in the same boat.

best wishes.

Sorry, I have read in multiple places that the Root directory is locked and you can't make changes. That is what sparked my question for this thread.

Congratz and welcome to the E90 club! ;)

This week I bought my ENET cable....
Nice, I actually built my own this July but haven't had a chance to test it yet. Hopefully I can get it to work.

best wishes.
Thanks, and ditto. Let Du Dis....




Anyone else care to chime in on the original question in the first post?

can you point to any place where you saw that info ? I am not sure if it's the case here but what usually happens with embedded systems is that the filesystem image is stored compacted in a hidden flash storage and gets decompressed to ram at boot time. the original compressed file system image is not updated with modifications done after boot time so they are lost at every boot. config files (prone to updates at user's choice) are usually stored in another place and gets restored at boot time. so the question perhaps couldn't be why the filesystem is locked but how to persist changes ?

again, I am not that familiar with CIC yet so I'm not saying that is the case here. I will let you know when I get my ENET cable.

Ahhh, ok. Good info. I'll have to try and find those articles where they said the Root was locked, but I bet you are correct about the flash storage.

I have seen the thread by @rhodesman, but guess I didn't stop to think about needing root permission to chmod since I'm a lowly Windows developer.... lol
