Problem
I feel something tickling me, what is it?
Solution
The description says that something is "tickling" me. It turns out that this was referring to network tickling. When I connected to the VPN,
tcpdump showed that 10.35.2.134 is periodically pinging me.
Let's open this in Wireshark to inspect the packet contents. The flag is in the ICMP data.
