SSH Connection Refused

When running ssh root@ blaa blaa blaaa -vvv I get this:

PS C:\Users\admin> ssh root@192.168.1.249 -vvv

I am on a Win 11 machine.. I tried uninstalling and re-installing the OPENSSH CLIENT.. No luck..

The problem seems to be I have no .ssh in my Windows User dir and I am not sure how to get it there.. I have tried manually creating the dir, but no luck..

My ssh seemed to work fine prior to my install of Windows 11...

Any hints, tips, suggestions would be most appreciated..

Hi, I'm just asking.... in the Settings - Libreelec... the SSH client is enabled (disabled by default).

michale32086 · February 11, 2023 at 3:51 PM

Yep... It's on...

Based on the output of running SSH, it seems it's a windows issue, not a KODI problem..

Which probably means I should be asking in a windows forum, but..

I'm using MobaXterm for terminal (and for litle upload-download) and Filezilla for SFTP (SSH File Transfer Protocol), now with Win11, worked well before with Win10 too. Don't remember to had any SSH issue with Libreelec.

Just for sheets and greens, I downloaded and installed PUTTY... Same problem..

Which leads me to believe it's a KODI/LE problem...

I'm happily connecting from Win11 (using the native support not PuTTY) and macOS to a range of LE devices using SSH, and if it didn't work for everyone there'd be a wave of forum posts complaining about it. So whatever the issue is, I'm confident it's local to your environment.

Make sure you didn't enable key-only auth. It doesn't stop SSH prompting for passwords. It does stop passwords from being accepted.

I also have no doubt about the existence of problems in LE (Nexus) 11 beta 1, installed on USB flash, in the network server services part. I have two examples: (1) I can't SSH via eth0/wlan0 IP, but I can via tailscale0 IP or via Web SSH Terminal addon with eth0/wlan0 IP, and (2) the zerotier service cannot be installed. My tests are made with Linux Ubuntu and Android Termius.

elonesna The output of journalctl -u sshd might be helpful after a failed connect.

I really never had a problem connecting before to my LE box with a Windows 11.. It's possible that a Microsoft update frak'ed up my setup.. That would be typical of M$ :^/

Where is this Key-Only Auth setting you speak of??

Thanx for the reply...

In the LE settings add-on, next to the SSH enable on/off .. and users occasionally get enthusiastic and flick everything on, which means they enabled key-only authentication (after which, passwords are unsurprisingly no longer accepted).

Problem solved...

And it was definitely a D-SAK problem. Dumb-Sheet At Keyboard... :^/

The IP for HOLODECK (my LE box) has always been 192.168.1.249...

But I had switched over my Gateway from AT&T to STARLINK... The STARLINK gateway had assigned a different IP.. I didn't catch on because there is another device at .249 so when I pinged it, I got a response..

Ironically enough, STARLINK assigned my own workstation as .249.. So I was pinging and trying to SSH into my own workstation!!

So, in the ever eternal words of Emily Litella....

Layer 8 networking issues are the hardest to solve

Your suggestion doesn't work for me.

(1) In an Ubuntu terminal I open SSH with tailscale0 IP and I don't have any problem.

(2) In a second terminal I open SSH with wlan0 IP and it gets blocked after entering the password.

(3) I go back to the first terminal and type journalctl -u sshd. The result does not say anything that is useful for something

Code

Jan 26 09:12:27 acemax-le systemd[1]: Starting sshd.service...

Feb 12 12:47:50 acemax-le sshd[3518]: Accepted password for root from 192.168.2.42 port 54852 ssh2

(4) A short time later and by chance I can no longer navigate with my Ubuntu PC because it has lost the addresses of the DNS servers

Note: I see strange things in log dates and device name

elonesna Yes, accepting the PW but failing afterwards is weird. Having no idea either.
