java - connection string for android to sqlserver -

-

i've started developing android application connects sqlserver db, i've connected db connection string :

connurl = "jdbc:jtds:sqlserver://" + _ip+ ":" + _port + ";" + "databasename=" + _db + ";usentlmv2=true;integratedsecurity=true";

but works if try on device connected same network in server connected because ip put in connection string 192.168.1.7. should make work if try in network ? i've tried replacing ip address ip address got what ip wont connect.

that's because you're behind nat , address isn't reachable outside world. need move server real ip address, or poke hole in nat , allow address rerouting.

but that's ok, because should never directly connect db anyway- not have allow db server reached public internet, have put login info in public app. totally insecure. should have webservice between , db. webservice should 1 password, , should data db , return in json or xml format.

i'm experimenting node , socks5-https-client . reason, tor hidden service ( .onion ) sites return connection error. for example, connecting duckduckgo ( 3g2upl4pq6kufc4m.onion ) works , returns html. however, connecting pirate bay ( uj3wazyk5u4hnvtk.onion ) or torch ( xmh57jrzrnw6insl.onion ) returns... error: socks connection failed. connection not allowed ruleset. what error mean? how can avoid it? here's code reproduce it: var shttps = require('socks5-https-client'); shttps.get({ hostname: '3g2upl4pq6kufc4m.onion', path: '', sockshost: '127.0.0.1', socksport: 9150, rejectunauthorized: false }, function(res) { res.setencoding('utf8'); res.on('readable', function() { console.log(res.read()); // log response console. }); }); the error seems caused 0x02 value in field 2 of server response. in summary the servers you're failing access don't support ...
