## 功能

### 连接到远程 SSH server 的网络

```shell
~ sshvpn client --ssh-addr xxx.xxx.xxx.xxx:22 --ssh-username root --ssh-password xxx
DEBU[0000] [sudo --preserve-env sshvpn client --ssh-addr xxx.xxx.xxx.xxx:22 --ssh-username root --ssh-password xxx]
DEBU[0001] [tun] ifconfig utun9 inet 223.253.0.1/32 223.253.0.1 mtu 1500 up
DEBU[0001] [tun] ifconfig utun9 inet6 ::1 prefixlen 128 alias
DEBU[0001] [tun] route add -net xxx.xxx.xxx.xxx/32 -interface utun9
DEBU[0001] [tun] route add -net xxx.xxx.xxx.xxx/32 -interface utun9
DEBU[0001] [tun] 223.253.0.1: name: utun9, mtu: 1500, addrs: [223.253.0.1/32 fe80::bed0:74ff:fe4c:9790/64 ::1/128]
DEBU[0001] networksetup -getdnsservers Wi-Fi
DEBU[0001] networksetup -setdnsservers Wi-Fi xxx.xxx.xxx.xxx
INFO[0001] you can use VPN now~
DEBU[0001] [TUN-RAW] IP-Protocol: IPv6HopByHop, SRC: fe80::bed0:74ff:fe4c:9790, DST: ff02::16, Length: 96
DEBU[0001] [TUN-RAW] IP-Protocol: IPv6HopByHop, SRC: fe80::bed0:74ff:fe4c:9790, DST: ff02::16, Length: 76

```

发现可以通

### 打开本地浏览器,然后电脑上所有的流量都是通过 SSH server 访问的

### 支持多种协议

- TCP
- UDP

### 跨平台

- macOS
- Linux
- Windows
