Thread: TraceRtGUI

Hey there!

The windows-utility "tracert" enables you to trace how you connect to a given address. It outputs the IPs you connect to during this connection-attempt.
Added a geolocation-parser that will try to resolve a given IP to a location.



Notes:
1. This application executes "tracert -d <ip/hostname>" on your machine by creating a new instance of cmd.
2. If "Get geolocation of IPs" is checked, this application will connect to "https://www.iplocation.net/", submit the currently processed ip and parse the html-response

Here's the code of the geolocation-parser:

Code:

public const string REGEX_PATTERN = @"<td width='80'>(?<ip>(.*?))<\/td><td>(?<country>(.*?)) <img(.*?)<\/td><td>(?<region>(.*?))<\/td><td>(?<city>(.*?))<\/td>";
        public const string GEOLOCATION_PROVIDER = "https://www.iplocation.net/";
 
private string[] GetGeolocation(string ip)
        {
            string[] returnVal = new string[3];
            if (ip.StartsWith("192.168"))
            {
                returnVal[0] = returnVal[1] = returnVal[2] = "<lan>";
                return returnVal;
            }
            InvokePostLogLine("geoloc", string.Format("Querying info of {0}", ip));
            using (WebClient client = new WebClient())
            {
                client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
                try
                {
                    NameValueCollection coll = new NameValueCollection();
                    coll.Add("query", ip);
                    coll.Add("submit", "Query");
                    byte[] data = client.UploadValues(GEOLOCATION_PROVIDER, "POST", coll);
                    string html = Encoding.ASCII.GetString(data);
                    string[] info = ExtractData(html, "EurekAPI");
                    if (info[0] == "-")
                        info = ExtractData(html, "DB-IP");
                    returnVal[0] = info[0];
                    returnVal[1] = info[1];
                    returnVal[2] = info[2];
                }
                catch (Exception ex)
                {
                    returnVal[0] = returnVal[1] = returnVal[2] = "<error>";
                }
            }
            return returnVal;
        }
        private string[] ExtractData(string html, string provider)
        {
            string[] returnVal = new string[3];
            string[] parts = html.Split(new string[] { provider }, StringSplitOptions.None);
            parts = parts[1].Split(new string[] { "Continent" }, StringSplitOptions.None);
            Match match = Regex.Match(parts[0], REGEX_PATTERN);
            if (!match.Success)
            {
                returnVal[0] = returnVal[1] = returnVal[2] = "<parsing failed>";
            }
            else
            {
                returnVal[0] = match.Groups["city"].Value;
                returnVal[1] = match.Groups["region"].Value;
                returnVal[2] = match.Groups["country"].Value;
            }
 
            return returnVal;
        }

I didn't make any piece of this program!
