I am building an intranet site that will display different lists based on the computer name because different computers are in different areas, is there a way (within a controller or model) to determine the client's computer name?
I have tried system.environment.machinename but that only returns the name of the server, any other ideas?
I got it working using the following:
string IP = Request.UserHostName;
string compName = CompNameHelper.DetermineCompName(IP);
code from compnamehelper:
public static string DetermineCompName(string IP)
{
IPAddress myIP = IPAddress.Parse(IP);
IPHostEntry GetIPHost = Dns.GetHostEntry(myIP);
List<string> compName = GetIPHost.HostName.ToString().Split('.').ToList();
return compName.First();
}
code in VB :
Dim myIP As IPAddress = IPAddress.Parse(Request.UserHostName)
Dim GetIPHost As IPHostEntry = Dns.GetHostEntry(myIP)
Dim compName As List(Of String) = GetIPHost.HostName.ToString.Split("").ToList
return(compName.First)
No. The client's computer name is not available in any way on the server. This is the nature of the http request-response. You only can have its IP address.
A workarounds could be to retrieve machine on the client from Flash/Silverlight (I doubt JavaScript) and put in into cookie which is available on the server with each request. But there is a whole stack of issues with this approach.
I think you are better off using one of these methods to tie a user to a location:
- a cookie that is set once the user self-selects their location
- having the user login to the site so that you can track them uniquely that way
- remembering user by IP address
There is no way of ensuring remote hostnames are unique. The same issue occurs with IP because of proxies, dynamic IP, etc., but I think it will be a little more reliable. Also, you can do geolocation by IP address.
Try this:
string name = Request.UserHostName;
The only way I know of to inspect the client is through the ServerVariables collection on the Request object (should be available for MVC code).
See http://www.4guysfromrolla.com/webtech/092298-3.shtml for more information. REMOTE_HOST and REMOTE_ADDR look like candidates.
Here's an IE-only solution. It works in IE8, with multiple security warnings.
<script type="text/javascript" language="javascript">
var ax = new ActiveXObject("WScript.Network");
document.write(ax.UserName + '<br />'); //logged in account name
document.write(ax.ComputerName + '<br />'); //Windows PC name
</script>
