Has anyone had any luck with chrooting to Debian on a DNS-343? I can't get chroot to work at all on the box. I expect that this is because fun_plug (0.5) is compiled for the 323, and not all hardware is analogous on the two devices.

[Fatman]

My understanding (I have never used it) is that all fun_plug does is get you in, so if you are in it's gold.  However I would not be surprised if chroot is not compiled into the DNS be default.  What exactly are you getting for errors, what exactly is your process?

Hello Fatman,

Thank you for helping me with this.

I've followed the two first methods listed in this article: http://wiki.dns323.info/howto:chroot_debian

Note that the first method is not using chroot at all, I'm only recounting it for completeness.

First method: Downloading debnas
The script properly unpacks linux.tar and creates the directory called linux.
I then try to ssh as myself, then root, and lastly try to telnet in.

$ ssh john@10.0.23.2
ssh: connect to host 10.0.23.2 port 22: Connection refused
$ ssh root@10.0.23.2
ssh: connect to host 10.0.23.2 port 22: Connection refused
$ telnet 10.0.23.2
Trying 10.0.23.2...
telnet: connect to address 10.0.23.2: Connection refused
telnet: Unable to connect to remote host

Second method: Proper chroot'ing
As I mentioned, I'm using ffp 0.5. Both telnetd and sshd are working properly.

I've downloaded and unarchived Debian Etch, though that last bit of information turns out to be beside the point, as I can't chroot anything; I keep getting 'Illegal Instruction'.
***

bash-3.2# /ffp/bin/busybox chroot /mnt/HD_a2/etch /bin/bash
Illegal instruction

My first assumption was that there was something wrong with the /mnt/HD_a2/etch/bin/bash, so I tried fetching Sarge, with the same result.
Oddly enough, I can't get it to execute the "local" bash with chroot, but that's with a completely different error:

bash-3.2# which bash
/ffp/bin/bash
bash-3.2# /ffp/bin/busybox chroot /ffp/bin/ bash
chroot: cannot execute bash: No such file or directory

I'd try to crosscompile from the bottom up, but since the source for 1.02+ isn't available, and I'd prefer not going back to 1.01, I'd prefer not to go that route.

your shell has to be relative to your new root path.  the problem is that the debian you have downloaded is compiled for a different processor.
