Hello!I))

I am reversing .NET web application which sends sockets to server through HTTP and RTSP protocol.

I just want to change IP address where I send requests.My problem is...I can't find this right place in code.

Look at that please.

public WebWrapper()

{

    this.UseProxy = false;

    this.UA = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.107 Safari/535.1";

    this.Proxy = new WebProxy();

    this.LastPage = "http://google.com/";

    this.cookies = new CookieContainer();

}

public string httpGet(string Address, [Optional, DefaultParameterValue(true)] bool Redirect)

string str;

try

{

IEnumerator enumerator;

this.WebRequest = (HttpWebRequest) WebRequest.Create(Address);

this.WebRequest.Method = "GET";

this.WebRequest.Headers.Set("Accept-Language", "en,en-us");

this.WebRequest.Headers.Add("Cache-Control", "no-cache");

this.WebRequest.CookieContainer = this.cookies;

this.WebRequest.UserAgent = this.UA;

this.WebRequest.Referer = this.LastPage;

 

I saw an example on MSN

WebRequest myRequest = WebRequest.Create("http://www.contoso.com");

In my example,WebRequest.Create(Address);

This string address is empty,Where is domain name?How can i find it please?

 

Here's picture of sending

It's better to make again the application because with reversing will be difficult to add the IP to connect to the server. Second, why do you want to change the IP to connect to the server? If you change the IP you will change the domain. The string domain has to be a web page that return any value. http://www.contoso.com it's a Microsoft web page so I think it will need something more to complete the return of any value. For example registration of any product.

If you can explain why and for what do you want to do will be better to help you.

LordCoder hello!

I have not source for this application.I just need to change ip with domain on my own ip address in that case.

I am newbie at .NET reversing because can't undestand all situation((

I used DotNet tracer for calls that it was ineffectually for me.I also have reflector and reflexil.

It's not registration or something else.It will be for sending sockets to server like a test app.

Can i inject my function like Socket.Connect(IpAddress,int32)?

Or will be easier to find and to change string?

Could you help me please?

 

It always sent sockets to 74.125.209.213 server.I'd like to change it

I think you should:

 

Show complete code you have or If, it is too much to paste here upload the source or file somewhere and someone who does take a look at least has all the info needed to give an answer at least.

 

Edit:

 

It always sent sockets to 74.125.209.213 server.I'd like to change it

 

74.125.209.213 = google

 

this.LastPage = "http://google.com/";

this.WebRequest.Referer = this.LastPage;

 

Maybe change http://google.com/", to your IP.

grrizzmo.

Thanks but it's not right solution.It is refferer for video that it's not "domain which i want to find"

"This string address is empty,Where is domain name?How can i find it please?"

 

string address =  74.125.209.213 = http://google.com/"

 

I don't get it.

@Elena

How do yo know 'Address' is empty?

 

I would use Reflector and analyze 'Assigned-by' references for 'Address' field ... you may find something interesting

Oh))))Yes!

I found it in function

 

 

this.LastPage = "http://google.com/";

this.LastPage = Address;

his.WebRequest = (HttpWebRequest) WebRequest.Create(Address);

 

Many thanks guys!You've friendly good community at this forum.
