The sample config is copied from my confd.conf, which should work for ncs.conf. Try the following changes: 1. Remove the whole line for tag showHidden 2. Change tag <customHeaders> to <custom-headers> I just tested it on NSO 4.7 ncs.conf, NSO starts OK. Probably not all headers are needed to solve your case, give it a try.   ... View more

You may have a different NED? I am using cisco-ios : admin@ncs# show devices tailf-ned-cisco-ios        -         urn:ios        [ ROUTER1 ]  tailf-ned-cisco-ios-stats  -         urn:ios-stats  [ ROUTER1 ]  Try replace "ios-stats:exec" by "exec" in the path? Or use ncs_cli config to check the exact syntax after live-status. admin@ncs(config)# devices device ROUTER1 live-status ?         Possible completions:   exec   Execute commands on device admin@ncs(config)# devices device ROUTER1 live-status exec ping 1.2.3.4 ...

Benny, The problem with your curl and JSON-RPC might be the 'th' parameter: the value should be something returned by 'new_webui_trans' call. See chapter 2 of ncs_webui.pdf for details. Could be also misspell in ' ios-stats:exec' in the path. Besides JSON-RPC, there is a simpler choice, i.e., REST APIs. Here is a working example I just tested, should be easy to repeat on your side. Step1: C reate a file, say ping.xml, with the following 3 lines: <ping>   <args>10.20.30.40</args> </ping> Step2: Run this command: curl -v -X POST -T ping.xml -u admin:admin 127.0.0.1:8080/api/operational/devices/device/ROUTER1/live-status/ios-stats:exec/_operations/ping Here is the output: *   Trying 127.0.0.1...   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                  Dload  Upload   Total   Spent    Left  Speed   0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0) * Server auth using Basic with user 'admin' > POST /api/operational/devices/device/ROUTER1/live-status/ios-stats:exec/_operations/ping HTTP/1.1 > Host: 127.0.0.1:8080 > Authorization: Basic YWRtaW46YWRtaW4= > User-Agent: curl/7.43.0 > Accept: */* > Content-Length: 46 > Expect: 100-continue > < HTTP/1.1 100 Continue < Server: < Allow: GET, POST, OPTIONS, HEAD < Content-Length: 0 } [46 bytes data] * We are completely uploaded and fine < HTTP/1.1 200 OK < Server: < Date: Wed, 30 Sep 2015 17:56:56 GMT < Allow: GET, POST, OPTIONS, HEAD < Cache-Control: private, no-cache, must-revalidate, proxy-revalidate < Content-Length: 253 < Content-Type: application/vnd.yang.operation+xml < Vary: Accept-Encoding < Pragma: no-cache < { [253 bytes data] <output xmlns='urn:ios-stats'>   <result> Type escape sequence to abort.

The following JSON-RPC call may also provide what you need: REQUEST: {"jsonrpc":"2.0","id":68,"method":"action","params":{"th":1,"path":"/ncs:devices/device{ROUTER1}/live-status/ios-stats:exec/ping","params":{"args":["10.20.30.40"]},"format":"normal"}} RESPONSE: {"jsonrpc":"2.0","result":[{"name":"result","value":"\r\nType escape sequence to abort.\r\nSending 5, 100-byte ICMP Echos to 10.20.30.40, timeout is 2 seconds:\r\n!!!!!\r\nSuccess rate is 100 percent (5/5), round-trip min/avg/max = 1/2/3 ms"}],"id":68} ...
