So I want to control my banana pi with my macbook pro using SSH. It is the first I am using ssh. So I followed a lot of different tutorials and it still does not work.
If I run :
pi#172.25.54.12
or
bananapi#172.25.54.12
or whatever name I try it answers me that
ssh: connect to host 172.25.*.*2 port 22: Operation timed out
and when I try
bananapi#localhost
or
pi#localhost
it answers me:
ssh: connect to host localhost port 22: Connection refused
I found my IP address doing ifconfig on my bananapi.
My bananapi is using bananian (debian for banana pi), and my mac is 10.10.3.
When I run sshd -T, I have:

Any idea?
edit:
so as suggested in the comments, I did a :
$ ls -al ~/.ssh
total 24 drwx------ 5 ***************** staff 170 12 mai 13:27 .
drwxr-xr-x 53 **************** staff 1802 12 mai 11:16 ..
-rw------- 1 ***************** staff 1766 12 mai 11:16 authorized_keys
-rw------- 1 ***************** staff 1679 12 mai 13:27 id_rsa
-rw-r--r-- 1 ***************** staff 429 12 mai 13:27 id_rsa.pub –
This is what I get as an answer. So I have a key in the authorized_keys file.
Do I have to send it (the public key) to my banana pi?
edit#2:
here is my adress less hidden 172.25.54.12 All I want for now is just connect my mac to my banana pi and control it as a server. So my Mac would be the client, and my banana pi my "host".
When I run
netstat -an | grep 22
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp6 0 0 :::22 :::* LISTEN
udp 0 0 0.0.0.0:32622 0.0.0.0:*
unix 3 [ ] STREAM CONNECTED 4122
unix 3 [ ] STREAM CONNECTED 2922 #/tmp/.X11-unix/X0
Basically what I did is, I followed some tutorial on the internet (like this one https://www.youtube.com/watch?v=0wn44MbxtZw) but it does not work.
edit#3:
I tried with a PC and puTTY, and I have got an error:
Network error: Network is unreachable.
Maybe it can help.
Edit#4
Ok I understood a part of my problem: I thought it was possible to connect directly my two devices without using the local network. I mean directly connect my banana pi to my mac just with one ethernet cable. But my goal is to be able to connect to my banana pi even when it is not connected to any network (is thath possible?), so I want to use an static IP address, is that a good idea?

Answer 1

Ok, so I found a way to do what I wanted to do. That means to connect directly my mac with my banana pi just with an ethernet cable (cross over ethernet cable).
I edited the network interface doing:
gedit /etc/network/interfaces
and then I modified the file this way
#interfaces (5) file used by ifup(8° and ifdown(8)
auto lo
iface lo inet loopback
#dhcp configuration
allow-hotplug eth0
#iface eth0 inet dhcp
#static ip configuration
auto eth0
iface eth0 inet static
adress 169.x.y.z
netmask 255.255.255.0
gateway 169.X.Y.*
So for address I put an IP really similar to my Mac IP adress (to get the mac IP address run ipconfig getifaddr en0)
And for gateway I put my mac IP address.
Then I connected my two devices with a cross over ethernet cable. And in my mac terminal I ran:
bananapi#169.x.y.*
and it worked!
Thank you
