SSH on Raspberry Pi3

[neda]

Hi,
I tried to deploy an application Qt for Raspbian (in raspberry pi 3).

I install ubuntu-17.04-desktop-amd64 and qt-opensource-linux-x64-5.8.0 on on my laptop.
I wrote an application with Qt 5.8 for windows. It works fine in windows and Ubuntu.

Get IP address of raspberry with"hostname -I": 169.254.181.63
I enable SSH on raspberry from Preferences menu.

In Ubuntu:

sudo service ssh status
.... 
.... Starting OpenBSD Secure Shell server.
.... Server listening on 0.0.0.0 port 22.
.... Server listening on :: port 22.
.... Started OpenBSD Secure Shell server.

I connect raspberry pi to laptop with Ethernet cable.
I create new device (Generic Linux Device) in "Tools -> Options…-> Devices -> Devices tab"

Host name: 169.254.181.63
SSH port:22
Username: pi
Password: 1 (set by me)

Result test:

Device test: SSH connection: Network unreachable.

In Ubuntu:

ssh  pi@169.254.181.63
ssh: connect to host 169.254.181.63 port 22: Network is unreachable

I edit the interface file to set the network configuration in raspberry:
sudo nano /etc/network/interfaces

source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0


allow-hotplug wlan0
iface wlan0 inet manual

But after reboot raspberry and execute "hostname -I", I have "192.168.100.100 169.254.181.63"

Your PC is probably not on the same network as the Pi
What is the IP address of your laptop?
I should look like 169.254.xxx.xxx

Or you can go the other way around and change the PI's IP to something like 192.168.xxx.xxx

The bottom line is they have to be in the same network domain, so numbers must be similar.

so you can use ie. 192.168.100.101 and 192.168.100.100

Thank you.
I set IP "192.168.1.100" for raspberry and "192.168.1.2" for laptop (Ubuntu) .

Result of "ssh pi@192.168.1.100"

But in Qt I same error in test device.
And after execute "hostname -I", I have "192.168.1.100 169.254.181.63"

Result of "route -n" in laptop:

Hi neda,

This is a networking problem and not Qt related. You will probably get faster answers on the ubuntu forums on how to set up the SSH connection.

Try 'sudo service ssh start' in Raspberry?
