Next message (by thread): [sysrepo-devel] callhome configuration not working
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
I did as follows sysrepo/build/src/sysrepoctl -L 4 --feature-enable=call-home  --module=ietf-netconf-server
sysrepo/build/src/sysrepoctl -L 4 --feature-enable=ssh-call-home  --module=ietf-netconf-server

by sysrepoctl -l command  could verify the feature is enable for the module 
sysrepo/build/src/sysrepocfg --import=stock_key_config.xml --format=xml --datastore=startup ietf-keystore
sysrepo/build/src/sysrepocfg --import=callhome_bk.xml --format=xml --datastore=startup ietf-netconf-server

I could see the changes got in startup data files and subsequently and started the sysrepod and netopeer2 in sequence  

stock_key_config.xml as follows 

<keystore xmlns="urn:ietf:params:xml:ns:yang:ietf-keystore">    <private-keys>        <private-key>            <name>ssh_host_rsa_key</name>        </private-key>    </private-keys></keystore>
callhome_bk.xm contetnt as follows 
<netconf-server xmlns="urn:ietf:params:xml:ns:yang:ietf-netconf-server">  <call-home>    <netconf-client>      <name>main</name>      <ssh>        <endpoints>          <endpoint>            <name>endpt_name</name>            <address>127.0.0.1</address>            <port>6666</port>          </endpoint>        </endpoints>        <host-keys>          <host-key>          <name>rsa_key</name>          <public-key>ssh_host_rsa_key</public-key>          </host-key>        </host-keys>      </ssh>      <connection-type>        <persistent/>      </connection-type>    </netconf-client>  </call-home></netconf-server>

Than the server was listening on 830 port 
I started the netopeer2-cli on the same server and than listen it was NOT getting any call home connection

Please let me know am I missing something 

RegardsVishal

 Hi,

It seems. Since guys from CESNET are already on leave, they probably won’t reply so soon, so I would suggest you to open an issue on Netopeer's github page for this.

Subject: Re: [sysrepo-devel] is an apostrophe not an allowed character in a key?

Hi,
I was able to successfully set with an apostrophe in the name of the key using your suggestion
      snprintf(xpath_buf, 256, "/ensemble-config:ensemble-config/ensemble-domains:domains/domain[name=\"%s\"]/owner-tag", name);

Where name = abcd'def


However a  get rpc error is returned when I tried to read it back s - is there something in netopeer2 preventing a get on a name with an apostrophe in it?

Hi,

rc = sr_set_item(sess, "/ietf-interfaces:interfaces/interface[name=\"giga'eth0\"]/type", &value, SR_EDIT_DEFAULT);

in the example there is more issue: The identity value should be prefixed by module name  
value.data.string_val = "iana-if-type:ethernetCsmacd";

Regards,
Lukas
