Re: [ubuntu-studio-users] weird ssh issue

[bart deruyter]

Hey all,

thanks for the reply Ross. I managed to solve it, though I still don't know
what the issue was. There was one thing I had not rebooted yet, the router.
Once I did that, it worked again.
I'm really sure I didn't enter the wrong ip-address because after I
rebooted the router I used the history of commands in the terminal and now
it did work, so it should have earlier too.

My guess is an IP conflict must have occurred because of a glitch in the
router.

Thanks,
Bart

Re: [ubuntu-studio-users] weird ssh issue

[Ross Gammon]

Hi Bart,

This is a bit off-topic for Ubuntu Studio, and you might have more
success asking in a forum more used to dealing with networking issues.

If you can connect to a different Raspberry pi from the same computer
plugged into the same network location, and if you can connect to this
Pi from a mobile phone, are you sure you are using the right IP address
in the ssh command? I assume the mobile phone is using a public IP
address and the router is set up to divert Port 22 connections to the
right internal IP address.

Can you connect to this pi from the other pi? Assuming they are on the
same subnet then this would confirm that the problem is on your Ubuntu
Studio computer setup.

Regards,

Ross

[ubuntu-studio-users] weird ssh issue

[bart deruyter]

Hello,

I've got a weird issue here. I'd like to move some of my finished videos to
a drive connected on a raspberry pi 3 device, which is running LibreElec.
I recently upgraded to 20.10, on my laptop, fresh install actually, with
the new KDE environment, and since then I can't reach this device over ssh.
I get this as result: ssh:
connect to host 192.168.1.xx port 22: No route to host
(last number is a real number, don't worry :-) )
username is correct, I don't even get the chance to enter a password.

When trying:
nmap -sn 192.168.1.0/24, the ip-address of the device is not listed.

The strange thing is, when I ssh to the same device with my android phone,
using Termux I do gain access without any issues at all. Checking on the
device, it should be there, the IP has not changed, checking the connected
ip-addresses on the router, it is listed too.

Even stranger is, I have another raspberry device I can connect to over ssh
with my laptop.

The only thing I can guess at the moment that might be causing it, is the
last number in the ip-address. It is quite high, maybe that has something
to do with it. The other raspberry device runs raspbian and has a much
lower ip-address. Is there some limit built-in some config file which
prevents scanning the ip-addresses from a specific number onwards for some
security reason I'm not aware of?

thanks in advance,
Bart
