SSH Configurator not working on Odroid N2+

[marcvl64]

When trying to ssh, I'm getting error "Connection Refused".

These are the log entries:

This Configurator did it's job. Perform a hard-power-off now. This configurator only works once and is no longer needed.

Well, looks like somehow you're booting from mmcblk1p0 instead of 0p0. Can you swap the drives? How common would you say this configuration is?

[marcvl64]

I don’t think I can change this. This is the standard Odroid N2+ server preconfigured for HA. It comes with an embedded 64g eMMC drive.

It’s pretty popular since its the basis for the Home Assistant Blue hardware.

[anduchs]

Same problem I have in #8 I guess I just messed up ODROID and BPI... ;-)

[marcvl64]

Is it easily fixable?

[marcvl64]

I noticed you made some changes (comment in #8). I uninstalled and reinstalled but it's still not working. I noticed a few extra lines in the logs:

[adamoutler]

It didn't find a config in mmcblk1p1. Can you do this from a terminal with proper permissions? You'll need to enable dangerous permissions to do this. I would like the output from a terminal of these commands.

You can paste the results to pastebin.adamoutler.com then hit ctrl-s and copy the url in the address bar here.

mkdir /tmp/0;
mkdir /tmp/1;
mkdir /tmp/2;
mount /dev/mmcblk1p0 /tmp/0;
mount /dev/mmcblk1p1 /tmp/1;
mount /dev/mmcblk1p2 /tmp/2;
ls -alR /tmp/0;
ls -alR /tmp/1;
ls -alR /tmp/2;

If this fails, try -alr instead of -alR. Awaiting response.

[marcvl64]

here it is:

None of the mounts worked. From my previous df, the external device is /dev/mmcblk1p4. Strangly enough, when I do another df, it shows me /dev/mmcblk0p4 as the external device. Not sure how or why it changed. When i tried to mount mmcblk0p1 or mmcblk0p2 it gives me error 'permission denied'. The system doesn't seem to have 'sudo' installed.

[adamoutler]

Looks like something went wrong with the first mount. Can you try that mkdir and mount again?

[marcvl64]

mkdir: can't create directory '/tmp/0': File exists
mkdir: can't create directory '/tmp/1': File exists
mkdir: can't create directory '/tmp/2': File exists
mount: mounting /dev/mmcblk1p0 on /tmp/0 failed: No such file or directory
mount: mounting /dev/mmcblk1p1 on /tmp/1 failed: No such file or directory
mount: mounting /dev/mmcblk1p2 on /tmp/2 failed: No such file or directory

The /dev/.... files you specify above do not exist on my system. The files are all /dev/mmcblk0px with x from 1 to 9.

[adamoutler]

No. In your first post you showed mmcblk1p4 is your data partition. Are you changing your configuration?

[marcvl64]

I know, that's pretty weird. I didn't change my configuration. But somehow the names of these files have changed. I don't understand how that's possible.

[adamoutler]

Did you disable Protection Mode in the terminal app?

[marcvl64]

No. I don’t even know what that is :)

[adamoutler]

This. Do this and try again.

[marcvl64]

Ok, tried that. Still getting 'connection refused'. The log looks like this:

You'll be fine after a reboot. It may take 2 full power-off-power-on reboots. It's done though and working properly.

[marcvl64]

you are right. I forgot to reboot. Everything worked after reboot. Thanks so much!

One add'l question: if I want to add another computer to the approved list, can I run your add-on again with a different key?

[adamoutler]

I think that worked at one point but no longer. You can try putting \n.

[marcvl64]

Since i have root access with 1 computer, I used that one to manually edit /root/.ssh/authorized_keys and add the second key. Everything works great. Thanks so much for your help.
