I want to have one computer look like multiple computers to a remote server. I'm thinking, different logins, maybe multi NIC (prefer not), and different IPs. I suppose a cookie could identify so that is why I'm thinking multiple logins.
Is there a router between the computer and the server?
What type of server? HTTP, FTP, file sharing?
What type of server application? Basic Apache, custom server?
What are trying to accomplish? Load testing?
