How I can obtain client hostname, local computer name and user name in c# and asp.net
asp.net, c#
Solution
Use `HttpRequest.UserHostAddress` and `HttpRequest.UserHostName` for client IP and machine name.
Assuming you have authentication configured correctly, you can get the client user from `IIdentity.Name`.
In the context of a `Page`, you can use `Request.UserHostAddress`, `Request.UserHostName` and `User.Identity.Name`.
Problem
I have the IP address, but for some reason I can get the name resolve correctly to show local computer name. I try few things and all of them is showing the server hostname? ``` ipadd = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; IPAddress myIP = IPAddress.Parse(ipadd); IPHostEntry GetIPHost = Dns.GetHostEntry(myIP); //userhostname = System.Environment.MachineName; //userhostname = Dns.GetHostName(); //Resolve ServerHostName not computer //userhostname = HttpContext.Current.Request.UserHostName; //userhostname = HttpContext.Current.Request.UserAgent; userhostname = GetIPHost.HostName; ``` For user name I am tring to use ``` nametext = WindowsIdentity.GetCurrent().Name; //Shows server name when deployed on server //when debuging and running localy shows correctly current user logged in //nametext = HttpContext.Current.Request.ServerVariables["LOGON_USER"]; // not returning anything ``` I switched authentication and no results ``` <authentication mode="Forms"> <authentication mode="Windows"> ```
