hi sir,
netopeer-server always show this when edit-config xml

rng and xsl has been deleted

Thanks！

[rkrejci]

can you provide the server's <hello> message?

[zhangk90]

this?

[rkrejci]

sorry, lost in formatting. No, I need to see the netopeer-server's hello message sent to client. If you are using netopeer-cli, the output of status command should be fine.

[zhangk90]

thanks!

[rkrejci]

can you provide the rest of the log from your original post? Does it end with an error returned to client or by not doing what is expected? And please avoid posting images, instead just copy paste the text and add formatting.

hmm, I don't know. Try discard-changes operation before edit-config the candidate or edit-config directly the running. Before the commit, check the content of the candidate via get-config to know what is actually happenning (before any operation, candidate should be the same as running and I'm afraid that in this case it is not).

And if possible, move to Netopeer2, this old version is no more supported, so I cannot spent time by checking what is going on. Sorry.

[zhangk90]

maybe the path defined error
.path = "/xy:vcpe/xy:interfaces/xy:interface/xy:name", .func =callback_xy_vcpe_xy_interfaces_xy_interface_xy_name

anyway，thank you very much

[michalvasko]

Hi,
you are incorrectly including non-existing container vcpe in the edit-config. It should work with your model with XML:

<?xml version="1.0" encoding="UTF-8"?>
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="1">

          <name>eth0</name>
        </interface>
      </interfaces>
    </config>
  </edit-config>
</rpc>
