Checking a TRIUMF VPN connection in Linux

Network Routing Table

Inspect your network routing table with

ip route show

Without VPN, the output will be similar to:

default via 192.168.1.1 dev wlp3s0 proto dhcp metric 600 
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.0.104 metric 600 
192.168.1.1 dev wlp3s0 proto static scope link metric 600

When TRIUMF VPN is active, there will be static routes through the VPN tunnel to TRIUMF, UBC and UVic.

default via 192.168.1.1 dev wlp3s0 proto dhcp metric 600 
13.107.136.0/24 dev vpn0 proto static scope link metric 50

Check connections to internal systems

With the routing table as above, check connections to an internal TRIUMF system.
e.g.  ping 142.90.100.19

Check host-name resolution with:  host www.triumf.ca
