Hi all,

I have tested the netopeer-server-sl a few days before, and yet, when I used netopeer-cli to connect netopeer-server-ml, I feel confused. According to the guidelines of netopeer-server-ml, I installed it step-by-step:

1. # cd /home/mobao/netopeer/server ; #./configure --with-dbus-services ; #make ; #make install
2. Configure NACM just like below:

3. #vi /etc/ssh/sshd_config. Add "Port 830". Restart sshd service.
4..Stop and disable firewall service.

BUT, when I try to open the netopeer-server, it looks like this:

[root@localhost mobao]# netopeer-server -v 3

It looks that it didn't work correctly. On the other side, I use cli to connect server, it looks like this:

netconf> connnect --port 830 --login root 192.168.0.237
libnetconf ERROR: Unable to connect to 192.168.0.237:830.
connect: connecting to the 192.168.0.237:830 as user "root" failed.

What's the matter?

Best Regards, thanks!

Hi Mobao,

netopeer-configurator and netopeer-server output seem correct. However, the third step you mentioned, editing the global system SSHD confguration file is not needed with netopeer-server, as it uses its own. You can try "ssh -p 830 ro...@192.168.0.237 -s netconf", it should output the hello message. If not, then there is another problem. To start I would suggest you delete the NETCONF SSH subsystem from "/etc/ssh/sshd_config" and try connecting again.

Regards,
Michal

Hi Michal,

Yesterday, on the server side, I followed your suggestion, and deleted the "Port 830" in /etc/ssh/sshd_config file (as it uses its own). Then, restart sshd service. When I typed in command: ssh ro...@192.168.0.237 -p 830 -s netconf in cli, it return result like below:

ssh: connect to host 192.168.0.237 port 830: No route to host

But today, It works as perfect ^_^:

ro...@192.168.0.237's password:

<hello>

...

</hello>

I don't know why? Whatever, I can continue my NETCONF testing work! thank you so much!
