Netopeer2-Server latest release installation behaving differently when installed at different times.

[Bhanupriya03]

On 13th December 2023, we installed netopeer2-server and all other packages from their latest released branches. Please find below the details of all the packages :

libnetconf2 : 2.1.37 libssh : 0.9.7 libyang : 2.1.128 netopeer2 : 2.1.71 openssl : 3.2.0 sysrepo : 2.2.105

We were able to compile all these packages successfully then. But today (19th December 2023), we tried installing all the above packages with the same steps and with the same versions but we are getting the following issue while doing 'make install' in netopeer2 :

Also, the system configurations are same for both the VMs : CentOS Linux release 8.4.2105

Please suggest how to proceed further.

Obviously, you are installing different versions of the packages (how else could possibly be the results different?). Most likely they are the latest releases but libyang had a separate release, which broke other projects. Please take the projects from their current master or devel branches, those should work. A new release is planned for early next year that should again work properly.

Hi Michal

Thank you so much for the response.

I tried compiling devel branches for all the projects and it compiled successfully. Also, I was able to start netopeer2-server successfully. However, I wasn't able to do password less connection between netopeer2-cli and netopeer2-server. I did the following steps for the same :

1. Append public-key to the authorized_keys
2. On netopeer2-cli, auth keys add public-key private-key
3. On netopeer2-cli, auth pref publickey 1
4. On netopeer2-cli, auth pref password 0
5. On netopeer2-cli, auth pref interactive 0
6. Restarted netopeer2-server

Wasn't able to achieve password less connection with these steps. Please suggest how to proceed further in this.

Right, you may have used the master branch if you wanted everything to work as before. We are still finishing some new functionality and you need to put the authorized keys into netopeer2-server configuration now, they are not automatically read from the system.
