I have Windows and Linux machines on the same subnet. My router configuration correctly tells me both their machine names, and their IP addresses. However, when I try and ping a Linux machine from a Windows machine, or ping a Windows machine from a Linux machine, I need to use IP addresses rather than names. If I'm pinging a Windows machine from a Windows machine, or a Linux machine from a Linux machine, the machine name correctly resolves without any hosts file entries.
Why is this?
I would have thought my router (D-Link DIR-655) would act as a DNS server itself. I see it has an option called "Enable DNS Relay", but from what I've read this won't help me. If it's relevant, the DIR-655 is used for internal traffic, with my ISP's Netgear DGN1000 used as a gateway to the Internet. It's on a different subnet though, and all my machines connect to my DIR-655, not the DGN1000.
What do I need to do to have host names automatically resolved within my subnet regardless of the operating system that they're running?
This sounds like my best option. I am still a little confused as to why the router itself doesn't include this functionality - it seems like the most logical place for it. Fortunately, I do have a box that will always be up, so I can use that as a DNS server. Thanks. – Kent Boogaart – 2011-09-18T08:07:48.667
