BSDCan - PSK password: on the back of your name badge
General notes
Baseline expectations:

- Endpoint addressing via DHCP
- RFC 1918 with NAT for Internet connectivity
- No TLS interception
This is what we’ve requested, but we won’t have people “on the ground” until Monday June 15. If there’s anything missing, hopefully we can request quick fixes, but no guarantees.
Many technical folks who travel frequently set up an SSH server on ports 80 and 443, in case they need some port forwarding.
