TIL: Some Netwokrking, Security & Vim
Spent some time having to debug VPN issues, had to monitor performance, & constantly check the routing table
ip r- shows your routing table
ip - show / manipulate routing, devices, policy routing and tunnels
iperf3- we used this to test the bandwidth between my machine & VPN server
iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6).
- While chatting networking with Maksim, I learnt about the concept of deep packet inspection. that fits right into my security notes. These could use a little more love tbh.
