Unable to connect via ssh

egor12092000 · Jun 10th 2024

Hello!

It's been about a week or so from the last time I worked with my OMV server. I am the only person working with it, and it is not connected to the internet, so there could be no changes in the configuration.

Suddenly, after a week on inactivity, I am trying to connect to my server via ssh, but i cant!

MOBA tells me "Network error: connection refused"

Tried to reboot the server - same reaction

Tried to reboot the ssh service through web interface, and while saving configuration, I suddenly face this error (pic. 1, under black lines is names of users, coverd for privacy reasons)

I guess, there is some problems with some ssh keys, but I cant even turn off "Open key authorization" option in web Services/ssh settings, same error appears when Trying to save it

Will be very grateful fo any advice!!!

Looks like there is some problem whith permissions
Question is - how to fix it without access to console?

BlueCoffee · Jun 10th 2024

Can you use the server plus monitor ?

egor12092000 · Jun 10th 2024

What is this exactly?

What is this exactly?

when you install OMV you do it on the main computer. plug that into a screen with keyboard.

egor12092000 · Jun 10th 2024

Ah, got it
Yeah, never thougth about than

egor12092000 · Jun 10th 2024

Problem resolved!!!

phisycly connected to the server, set chmod for etc/ssh to 700, now everything working!

It remains to be seen, how on earth permissions was set to 777...

This looks like something I need to do, as I am having the same issue (though permissions are showing as 0775 on my error log).

Due to being too late at night here, I will need to wait until the morning.

How do you set the chmod once connected via Monitor and keyboard?

DaveR1974 · Aug 3rd 2024

Thanks for the info.

Due to my monitor not working, I had to wait for a new one to be delivered today. It has now arrived, and I have tried to chmod the permissions. No error messages came up, so I assumed it was fixed.

On checking via the web dashboard (after a reboot), ssh is still red, and I'm still getting the error when trying to disable (so I can enable).

Due to the error text being over 10,000 characters, I have attached it.

I have tried to chmod the permissions.

Did you check the file permissions after that?

It seems they are not changed

I am a novice with this. I know how I messed the permissions up. To access and edit the grub file in Windows, instead of SMB sharing just the relevant folder, I SMB shared the whole etc folder... WHOOPS!!!

The share has since been removed, but the damage is done. Sudo was also messed up because of this, but I have managed to fix that.

How do I check? Do I need to chmod each file individually?

I do not understand this completely, but did you change the permission of the complete /etc folder?

DaveR1974 · Aug 4th 2024

Making the entire etc folder shared changed the permissions, yes.

And never ever create shared folders pointing at a system folder.
