# Split VPN Manager

Simple script to manage vpn inside net namespaces and run programs inside of them.

> Currently only supports openvpn, but wireguard and openconnect are in my plans.

## Usage

```
Usage:
  ./split-vpn-manager.sh launch_openvpn --name NETNS_NAME --config CONFIG_FILE --auth AUTH_FILE
      starts a vpn connection and create the net namespace

  ./split-vpn-manager.sh run NETNS_NAME CMD
      runs a command in the specified net namespace

  ./split-vpn-manager.sh inspect NETNS_NAME
      list all processes using TCP/UDP sockets inside the specified net namespace

NOTE: Always run this script with privileged permissions (currently not)
```
