Missing in documentation

[timwhite]

@cchamb2 We actually don't want netplan to touch the NIC. So far in my testing netplan hasn't touched the second NIC, so things are working correctly. I'll add documentation for how to stop netplan touching the NIC if it's already done something to it.
CoovaChilli will handle setting up the second NIC through the tunnel it creates (normally tun0)

[cchamb2]

The problem is that the second NIC isn't touched at all.  According to ifconfig, it's not there. The complete output of ifconfig: ================== charles@hotspot:~$ ifconfig enp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet 192.168.0.200  netmask 255.255.255.0  broadcast 192.168.0.255         inet6 fe80::c225:e9ff:fe1d:bbfb  prefixlen 64  scopeid 0x20<link>         inet6 2600:8800:7a00:3510:c225:e9ff:fe1d:bbfb  prefixlen 64  scopeid 0x0<global>         ether c0:25:e9:1d:bb:fb  txqueuelen 1000  (Ethernet)         RX packets 592205  bytes 84614511 (84.6 MB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 632554  bytes 92128217 (92.1 MB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536         inet 127.0.0.1  netmask 255.0.0.0         inet6 ::1  prefixlen 128  scopeid 0x10<host>         loop  txqueuelen 1000  (Local Loopback)         RX packets 94  bytes 8956 (8.9 KB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 94  bytes 8956 (8.9 KB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 ============== enp4s0 is the NIC connected to the router, with Internet access.  It's running on Ubunu Server 18.04, which only activates one NIC on installation. The second NIC should show up as enp2s0. There is no second NIC for connectivity to the access point. Charlie

That's to be expected. Until CoovaChilli is running correctly, ifconfig won't show you the interface (as it's in a down state). ifconfig -a should show it though.
In the current V4 packages, make sure you head to /grase/settings/advanced/ and set the networkLanInterface and networkWanInterface correctly otherwise CoovaChilli won't start.

For example, my test VM before CoovaChilli has started shows the following (showing ifconfig -a will show all the network interfaces. Note that ens9 is missing the UP flag)

After I configure networkLanInterface and networkWanInterface and the cronjob (runs every 5 minutes) picks up the change and configures dnsmasq and coovachilli correctly I get the following. ens9 now has the UP flag and no IP address, and tun0 is running with the LAN IP address.

First run wizard mostly implemented (networking part is). https://grasehotspot.org/documentation/v4-nightly-builds/ has details about only setting up WAN interface. If we need, we can add netplan commands to docs as well.
