My network here is hosts file based, and the N-M people are convinced their way is the only way. So I make /etc/resolv.conf immutable, and nuke /usr/sbin/resolvconf just to be sure that what I set, stays set. Now I need to find whats starting wlan0 and kill that. But thats a different problem. > ---------------------------------------------------------------------- >- > > #Setup network manager > > sudo nano /etc/network/interfaces > #Comment out > #iface wlan0 inet dhcp > #iface default inet dhcp > #iface wlan1 inet dhcp > #iface eth0 inet manual > # Use control key and x to save and save to default > > ---------------------------------------------------------------------- >--- > > #Update rpi firmware without over writing rt kernel > > sudo apt-get install rpi-update > sudo SKIP_KERNEL=1 rpi-update Took around 2 hours, so I fired up the weed eater for half that.

I had saved them off the card it was using, but have not copied them back. Tomorrows first operation. After spending the day on this, I'm wasted. Etcher, v1.0.0 is not ready for prime time yet, it died on the first attempt to put the emlid iso on the card, at 70%, and froze solid, repeated it, froze at 67%. Reinserted the card to automount it, looked like it was finished, so took the card to the pi, booted and worked. Ill configured, but worked, so I continued with the install as if it had done. > Tim March Many thanks Tim, I'll find out if it works in the morning Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
