I have an Carrier I-VU "Server" that died and I'm resetting it up in a new home and will attempt to VM it. I was able to remove the drive from it's intel mini PC and boot up in another PC. Linux is great that it just booted right up and all of the software on it is working!

I was able to clone the drive so I can play with this thing.

I would like to get the security on this thing updated since the Log4J stuff hit.

I'm fairly new to Linux so please forgive any stupid questions.

On boot it shows that it is CJ Linux 2.0. I was able to get into GRUB and here is the boot config:

root=(hd0,0)
kernel=/boot/bzImage ro root=/dev/sda1 quiet


I'm trying to figure out how to get to a command prompt and figure out what exact CJLinux is. It looks like the bzImage just loads linux and runs the Carrier software and disables any keyboard inputs.


Adding a "3" on the end of the kernel command does not give me a prompt.
The Grub is old. "ls" does not work.

Anyone know what CJLinux is?
Can anyone point me to a guide that I could migrate the carrier software off to another linux distro?

Thanks in Advanced

Welcome to LinuxQuetions.

There was a previous post basically asking the same question but I can't seem to find it...

Since it is basically a commercial product there isn't much information in the free world and all I can remember is that it is a specialized embedded linux for running their HVAC system. From what I can remember from that previous thread that it was not laid out i.e file/directory structure like a typical distribution. Depending on how the server was written it may or may not work with newer libraries so trying to migrate might not be possible.

My first thought would be to contact Carrier to see if the server even runs Apache or Java.

I love Search-fu! Was your couldnt-find reason: the infamous LQ search timeout?
I use(d): results as *Threads* (for cjlinux &got lucky; can't search just 2 letters cj)

Yes on the thread and timeout.

Thank you...
