How get client (user) machine name (computer name) with jQuery or JavaScript or server-side codes. (scrutiny of possible ways)

I was working on Retrieving IP address and client machine name for few days on the internet (not on the local network)

so I found some ways for getting IP-address , but I couldn't find a way for getting client machine name or gathering some info about my web site users ?

I know there are many duplicate threads about this issue out there , but many of them are old or do n't work.

the below server side codes return SERVER NAME 开发者_如何学PythonNot client computer name !

string UserHost_ComputerName4 = Dns.GetHostName();//Server Name
string UserHost_ComputerName5 = Environment.MachineName;//Server Name  

and the below line have error on user-side , but it works on server-side page running :

 string UserHost_ComputerName3 = Dns.GetHostEntry(Request.ServerVariables["REMOTE_ADDR"]).HostName.ToString();//Has Error

Would you lead me to a possible and workable ways (JavaScript or jQuery or server side) for getting client (users who are visiting my web site) machine name?

Try this:

string PCName = Dns.GetHostEntry(Request.ServerVariables["REMOTE_ADDR"]).HostName;

But if you want Name of Host PC

string HostPCName = Dns.GetHostName();

As far as I remember, in order to get:

• Request.ServerVariables["REMOTE_ADDR"]
• Request.ServerVariables["REMOTE_HOST"]
• Request.ServerVariables["REMOTE_USER"]

you have to enable Reverse DNS Lookup for you IIS.

p.s. atm I'm not able to test it myself, so I'm not quite sure if this will solve ur problem

Not entirely sure on all the ways you can do this, but it would be possible through ActiveX, which could be a problem as that only works in some browsers. I don't believe there is a way you can do it with pure javascript, and it's not possible serverside as the server does not get access to such details of it's connected clients.
