Problem connecting to server

[peter...@gmail.com]

Hi,

I have some trouble connecting to the netopeer server, and I don't know why. I was able to connect successfully before, and suddenly I can't.

The netopeer-cli and server side messages are shown below.

The netopeer-cli side:

[root@localhost ~]# netopeer-cli

netconf> connect 192.168.0.141 --login root -p 830 

libnetconf ERROR: Unable to connect to 192.168.0.141:830.

connect: connecting to the 192.168.0.141:830 as user "root" failed.

The netopeer server side:

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

Hi Peter,

for one, the "-p 830" option for netopeer-cli connect is redundant, that is the default. Second, your server fails to start (obviously you cannot connect) and it says exactly why, please read the messages more carefully.

netopeer-server[5488]: Datastore file /usr/local/etc/netopeer/modules.conf.d cannot be opened (Is a directory).

Regards,
Michal

Probably, you have added ietf-softwire using netopeer-manager with a wrong parameter specifying the file where the configuration data will be stored (see the man page for netopeer-manager).

Hi,

 #/usr/bin/netopeer-configurator shows that the default location of the YANG modules is /usr/local/etc/netopeer/modules.conf.d and that is the path I chose for the --datastore option of the netopeer-manager command. Is this wrong?

Regards,

Peter

yes, it is wrong. netopeer-configurator actually does not say anything about YANG modules, but about the Netopeer (i.e. transAPI) modules. The {prefix}/etc/netopeer/modules.conf.d/ directory contains netopeer specific configuration files describing the transAPI modules to be loaded by the server (one of those parameters can be also the datastore file).

netopeer-manager man page says:

--datastore DATASTORE
               Specifies path to the file where the configuration data will be stored. If not specified, datastore is implemented as empty and it will not able to store any configuration data.

The datastore file stores the configuration data managed by the netopeer-server. When you run the server for the first time, the datastore file is supposed to be empty or to not exist at all (it is created). It is the place where the server gets the startup configuration of the specific transAPI module when it boots up.
