newbie question - getting started with FTP

newbie question - getting started with FTP

Hi - this is my first adventure with Wyse and I'm keen to try and understand some of the problems I am encountering.

I have a C10LE on a test environment in a workgroup, not a domain, and a laptop running an FTP server pointing at the wnos.ini

I don't have any way to set DHCP options as it's a small home/test network with limited functionality so I'm manually configuring the file server/path option to point at the FTP server I have. However whenever I put an IP address in I get an error that it can't connect to a host name that I don't recognise, I'm guessing something that has been saved locally previously. I do see a request come in to my FTP server but session is closed by peer instantly. When I enter a name into the file server option it tries to connect to the name, but being in a workgroup it can't resolve it.

So my questions are:
Is there a local host file that can be manipulated?
Is this the correct way to configure the FTP server if I don't have a DHCP server with options to set?

PS - I don't currently have the option for administrator mode

Thanks for reading.
