-

is possible write program in c able set msl udp-packet , receive return information of death, can information package was? read can set in os how possible programs traceroute use headeroption udp?

are talking time live (ttl)? should able use ip_ttl socket option (see ip(7)) set time live of packets sent on socket. if packet goes through enough hops ttl become zero, node discards packet should send icmp time exceeded message originating host. receive error, think might have create icmp socket. traceroute does, might want take @ source code.

i have collections of objects structure this: { "_id" : objectid("5233a700bc7b9f31580a9de0"), "id" : "3df7ce4cc2586c37607a8266093617da", "published_at" : isodate("2013-09-13t23:59:59z"), ... "topic_id" : [ 284, 9741 ], ... "date" : numberlong("1379116800055") } i'm trying use following query: db.collection.find({"topic_id": { $in: [ 9723, 9953, 9558, 9982, 9833, 301, ... 9356, 9990, 9497, 9724] }, "date": { $gte: 1378944001000, $lte: 1378954799000 }, "_id": { $gt: objectid('523104ddbc7b9f023700193c') }}).sort({ "_id": 1 }).limit(1000) the above query uses topic_id, date index not keep order of returned results. forcing use hint({_id:1}) makes results ordered, nscanned 1 million documents though limit(1000) specified. what missing?

c# - Attribute value in root node of xml Linq to XML -

while parsing xml linq xml, came across strange behaviour (atleast me). below first xml parsed `<?xml version="1.0" encoding="utf-8"?> <testrun> <unittestresult testname = "arun" outcome = "i"> </unittestresult> <unittestresult testname = "arun1" outcome = "i"> </unittestresult> </testrun>` my code looks xdocument doc = xdocument.parse(filecontents); var result = doc.descendants("unittestresult"); the above works fine. if root node contain attributes same code not working. reason. xml sample below <?xml version="1.0" encoding="utf-8"?> <testrun id="7903b4ff-8706-4379-b9e8-567034b70abb" name="inaambika@inbelw013312a 2016-02-26 16:55:14" runuser="stc\inaambika" xmlns="http://microsoft.com/schemas/visualstudio/teamtest/2010"> <unittestresult testname = "arun" outcome = "...
