I apologise for being a Linux newbie. Appears the udhcp service needs to be configured? But if it wasn't then I'd have no IP or connectivity? (Assuming this DHCP)
--

It's a non-default private address but still should work? (not 192.168.0.0)
and connectivity is obviously working:
oot@eve-ng-pro:~# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

64 bytes from 8.8.8.8: icmp_seq=2 ttl=117 time=19.4 ms


Anyways, thanks for any help would be appreciated.

Cheers,
Tom

It seems that you had changed network subnets in the eve which were hardcoded
