1. 下載源碼 git clone https://github.com/meyerd/n2n.git
2. 安裝工具
- brew cask install tuntap
- brew install openssl
- brew install cmake
3. 編譯n2n
- ~/n2n/n2n_v2$ mkdir build
- ~/n2n/n2n_v2$ cd build
- ~/n2n/n2n_v2/build$ cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl ../

- -- The CXX compiler identification is AppleClang 8.1.0.8020042

- ~/n2n/n2n_v2/build$ sudo make install
- sudo chmod -R 777 /usr/local/sbin

4. 創建n2n連接
sudo edge -d n2n0 -c mynetwork -k encryptme -u 99 -g 99 -m 3C:A0:12:34:56:78 -a 1.2.3.4 -l a.b.c.d:xyw -v -f
5. 如果出現錯誤提示ERROR: Unable to open tap device，可以通過下面方式安裝虛擬網卡
- brew cask install tuntap
- 查看是否有如下兩個內核擴展
- ls /Library/Extensions/tap.kext
- ls /Library/Extensions/tun.kext
- 校驗內核擴展的參數
- find /Library/Extensions/{tap,tun}.kext/ -type f | xargs shasum
- 加載內核擴展
- sudo /sbin/kextload /Library/Extensions/tap.kext
- sudo /sbin/kextload /Library/Extensions/tun.kext
6. edge幫助
- edge -d < tun device > -a < tun IP address > -c < community > -k < encrypt key > -s < netmask > [-u < uid > -g < gid > ][-f][-m < MAC address > ]
- -l < supernode host:port > [-p < local port > ] [-M < mtu > ] [-t] [-r] [-v] [-b] [-h]
- -d < tun device > | tun device name
- -a < tun IP address > | n2n IP address
- -c < community > | n2n community name
- -k < encrypt key > | Encryption key (ASCII) - also N2N_KEY = < encrypt key >
- -s < netmask > | Edge interface netmask in dotted decimal notation (255.255.255.0)
- -l < supernode host:port > | Supernode IP:port
- -b | Periodically resolve supernode IP
- | (when supernodes are running on dynamic IPs)
- -p < local port > | Local port used for connecting to supernode
- -u < UID > | User ID (numeric) to use when privileges are dropped
- -g < GID > | Group ID (numeric) to use when privileges are dropped
- -f | Fork and run as a daemon. Use syslog.
- -m < MAC address > | Choose a MAC address for the TAP interface
- | eg. -m 01:02:03:04:05:06
- -M < mtu > | Specify n2n MTU (default 1400)
- -t | Use http tunneling (experimental)
- -r | Enable packet forwarding through n2n community
- -v | Verbose
