Re: Offline

Just work your way up the network osi model in troubleshooting. Everyone
should learn some networking these days, one way or another (speaking as a
bofh network guy that deals with non-networking app and developers folk
commonly - don't be part of the problem).

####
## Layer 1/2, got link? note "state"

> ip link

## If no link, check cable plugged in for blinky lights

####
## Layer 3, got ip?

> ip addr

## If no ip, check dhcp on the network
## Optional: Set static ip for temporary troubleshooting, insert proper
subnets here:

ip addr add 192.168.1.100 255.255.255.0 dev eth0
ip route add default 192.168.1.1

####
## Layer 3, verify arp to gateway

ip nei | grep `ip route | grep default | awk '{ print $3 }'`

## If no arp for gateway, check router/switch network

####
## Layer 3, ping the gateway (whatever that is for you)

ping `ip route | grep default | awk '{ print $3 }'`

## If no response, check prior steps again

####
## Layer 3/4, verify resolv.conf dns resolution and life beyond default
route

ping google.com

## If no dns life outside router, check the router has connectivity to the
internet

####
## pull up a browser to google.com to test layer 4-7 stuff
