Hi Michal, Can I achieve to revert back the configuration in case of validation failes? Can I get any examples for this?

Hi Michal, User authentication is failing when I try to connect from Netconf cli. I am able to connect through root user and password . Do we need to enable anything for user authentications in the code?

Yes Michal.

You can manually edit the configuration using sysrepocfg -E vim -m ietf-netconf-server, for example. You can find example segments of the supported configuration in netopeer2/example_configuration/ssh_listen.xml. — Reply to this email directly, view it on GitHub<#3281 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/BFY5QEETFQXTL34L3KL3AWTZCBPQLAVCNFSM6AAAAABG5XWNXCVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDCMBWG44DKNJRGQ>.

Hi All, I was tried with lock option to lock the running database. I was able to edit the running database even after the “lock” . is that expected behavior?

Hi All, Getting the following issue while executing the merge_config.sh script. It was working earlier. I followed the following steps ./setup.sh ./merge_hostkey.sh ./merge_config.sh [ERR] Invalid leafref value "genkey" - no target instance "/ks:keystore/ks:asymmetric-keys/ks:asymmetric-key/ks:name" with the same value. (Data location "/ietf-netconf-server:netconf-server/listen/endpoints/endpoint[name='default-ssh']/ssh/ssh-server-parameters/server-identity/host-key[name='default-key']/public-key/central-keystore-reference".) [ERR] Validation failed. sysrepocfg error: Failed to merge edit data (Validation failed) I am not able to understand why this issue is coming. Thanks Samba
