Unfortunately, I'm fresh out of Pis but I may be able to cobble together something using a mobile phone or laptop connected by Ethernet instead of via the Belkin Router. I was already thinking of substituting the Belkin Router with another one, if I can find a suitable device, but your suggestion would remove yet another variable. I was also thinking of starting again from scratch with a clean installation of Raspbian and building the RPi Router from there, before ever attempting something like NoDogSplash. At least then I would know that I haven't introduced some incompatibility along the way. > Given `address', ...

One final question. If I open a default copy of /etc/network/interface, it says that the file is intended to be used with dhcpcd.conf. Do I still need to define the static IP address of eth0 in both places or just here? -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2018-07-03 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:[email protected] / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
