mtu=1464
local_ip=192.168.0.1
port=10088
- Client configure like this:
[client_0]
mode=client
key_file=cli.key
iv_file=cli.iv
vnd_id=0
tap_name=tap0

For SylixOS
- Step 1: Add vnd interface parameter in /etc/ifparam.ini
[vnd-X]
# X is a number of vnd ID)
enable=1
# Enable(up) this interface
ipaddr=x.x.x.x
# Virtual network ip address
netmask=x.x.x.x
# Virtual network netmask
mac=xx:xx:xx:xx:xx:xx
# Virtual network MAC address, If not, the system will use random numbers
- Step 2: Use 'vnd' command add a virtual net device.
vnd add X
# X is a number of vnd ID
- Step 3: Use 'kidvpn' to create a VPN connect.
kidvpn x.ini sector password
# 'x.ini' is vpn config file, 'sector' is ini sector which we will use, 'password' is password
- Step 4: Use 'route' command add some route entry to system, make route rules.
For Linux
- Prepare for work:
sudo apt-get install openssl
# Install OpenSSL library
sudo apt-get install libssl-dev
# Install OpenSSL develop library
make
# Build kidvpn target
- Step 1: Add tap interface
sudo tunctl -t tapX -u root
# X is tap number
sudo ifconfig tapX up
# Enable tapX network
- Step 2: Use 'ifconfig' command set tapX address
ifconfig tapX inet x.x.x.x netmask x.x.x.x
- Step 3: Use 'kidvpn' to create a VPN connect.
sudo ./kidvpn x.ini sector password
# 'x.ini' is vpn config file, 'sector' is ini sector which we will use, 'password' is password
- Step 4: Use 'route' command add some route entry to system, make route rules.
