self signed x509 certificate issue in MQTT mosquitto using c# -

-

i using mqtt library in c# , following url. http://www.embedded101.com/blogs/paolopatierno/entryid/366/mqtt-over-ssl-tls-with-the-m2mqtt-library-and-the-mosquitto-broker implementing url while connecting client localhost server following error occur:-

c:\program files\mosquitto>mosquitto -c mosquitto.conf -v 1438001198: mosquitto version 1.4 (build date 27/02/2015 21:01:03.50) starting 1438001198: config loaded mosquitto.conf. 1438001198: opening ipv4 listen socket on port 8883. enter pem pass phrase: 1438001224: new connection 10.112.154.82 on port 8883. 1438001224: openssl error: error:140890c7:ssl routines:ssl3_get_client_certifica te:peer did not return certificate 1438001224: socket error on client <unknown>, disconnecting.

my code is:- 

x509certificate certificate = new x509certificate(@"d:\poc\abhinav\cert\cert\m2mqtt_ca.crt", "india@123");   mqttclient client = new mqttclient("10.112.154.82", 8883, true, new x509certificate(certificate));       string clientid = new guid("b0ca37b1-8a90-4a59-9665-fd8504357165").tostring(); client.connect(clientid);

the error:

c# error:-{"a call sspi failed, see inner exception."}

can 1 suggests me how implement certificate in mqtt using mosquitto.

it seems mosquitto broker waiting client certificate client authentication. m2mqtt supports server authentication described in above article. reading mosquitto documentation here : http://mosquitto.org/man/mosquitto-conf-5.html seems "require_certificate" set true (require client certificate). need set false.

paolo.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
