I am using the cd, i can get into OS but it is no help.

Link encap:local loopback

I can get in with VNC.

When I try this with my info I get this error.

ifconfig enp0s4 1.2.3.4 netmask 255.255.255.0
route add default gw 1.2.3.254
echo "nameserver 8.8.8.8" > /etc/resolv.conf


SIOCSIFNETMASK: no such device
route: hostname lookup failure
ifconfig: `--help' gives usage ...

So my server is on lockdown and I can't get the files from it. I have tried this but to be honest I am in way over my head.

Is there anybody who could dumb this down so i can get some very crucial files back?
