Hi Andrej, Peter, Yoyo, and David, |
| 2 |
|
| 3 |
I was quite in a hurry the last two weeks, that is why I not have |
| 4 |
replied. Sorry. |
| 5 |
|
| 6 |
But this weekend finally i got the desktop:freerunner usb networking |
| 7 |
running. The crack point was at the desktop linux distro I use |
| 8 |
(gNewSens) not at shr. |
| 9 |
I list here my solution: |
| 10 |
|
| 11 |
1) David / Yoyo: is sshd running? |
| 12 |
It was not. I had even to install and start it: |
| 13 |
elm@firebolt:~$ sudo apt-get install openssh-server |
| 14 |
elm@firebolt:~$ sudo /etc apt-get install ssh |
| 15 |
elm@firebolt:~$ sudo /etc/init.d/ssh start |
| 16 |
elm@firebolt:~$ ps aux | grep -i ssh |
| 17 |
root 4950 0.0 0.0 5320 996 ? Ss 20:28 0:00 /usr/sbin/sshd |
| 18 |
elm 6679 0.0 0.0 312 108 pts/0 R+ 20:50 0:00 grep -i ssh |
| 19 |
|
| 20 |
|
| 21 |
2) Yoyo: you often asked me about the subnetwork. |
| 22 |
The mayor problem was that the subnet between the freerunner (eth1: |
| 23 |
192.168.0.something) and the desktop (eth0: 192.168.0.57) was |
| 24 |
overlapping. My solution is to move the eth1 usb connection to the |
| 25 |
freerunner form 192.168.0.0/24 to 192.168.202.0/24. |
| 26 |
The majority of the needed information I learn from the following pages: |

| 33 |
In practices it looks like this: |
