mtcp

mtcp is a Rust TCP/IP stack that presumes a perfect network layer.

Usage

cargo build --release

An example that listens on tun1 interface, forwards traffic through 127.0.0.1:3148 and uses remote DNS for resolving domains is

sudo ip tuntap add dev tun1 mode tap user $YOUR_USER_ID
sudo ip a a dev tun1 10.0.0.1/24"
sudo route add default gw 10.0.0.2 metric 6

cargo run --release -- '127.0.0.1:3148' --dns 8.8.8.8 --tun tun1

sudo ip route del default via 10.0.0.2

Note

• IPv4 only
• Use native threads
