### P2P Mode
|
||||
|
||||
**xtcp** is designed for transmitting a large amount of data directly between two client.
|
||||
|
||||
Now it can't penetrate all types of NAT devices. You can try **stcp** if **xtcp** doesn't work.
|
||||
|
||||
1. Configure a udp port for xtcp:
|
||||
|
||||
```ini
|
||||
bind_udp_port = 7001
|
||||
```
|
||||
|
||||
2. Start frpc, forward ssh port and `remote_port` is useless:
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000

|
||||
local_port = 22
|
||||
```
|
||||
|
||||
3. Start another frpc in which you want to connect this ssh server:
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x

### 点对点内网穿透
|
||||
|
||||
frp 提供了一种新的代理类型 **xtcp** 用于应对在希望传输大量数据且流量不经过服务器的场景。
|
||||
|
||||
使用方式同 **stcp** 类似，需要在两边都部署上 frpc 用于建立直接的连接。
|
||||
|
||||
目前处于开发的初级阶段，并不能穿透所有类型的 NAT 设备，所以穿透成功率较低。穿透失败时可以尝试 **stcp** 的方式。
|
||||
|
||||
1. frps 除正常配置外需要额外配置一个 udp 端口用于支持该类型的客户端:
|
||||
|
||||
```ini
|
||||
bind_udp_port = 7001
|
||||
```
|
||||
|
||||
2. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口:
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
|
||||
[p2p_ssh]

||||
type = xtcp
|
||||
# 只有 sk 一致的用户才能访问到此服务
|
||||
sk = abcdefg
|
||||
local_ip = 127.0.0.1
|
||||
local_port = 22
|
||||
```
|
||||
|
||||
3. 在要访问这个服务的机器上启动另外一个 frpc，配置如下:
|
||||
|
||||
```ini
|
||||
# frpc.ini
|
||||
[common]
|
||||
server_addr = x.x.x.x
|
||||
server_port = 7000
|
||||
|
||||
[p2p_ssh_visitor]
|
||||
type = xtcp
|
||||
# xtcp 的访问者
|
||||
role = visitor
|
||||
# 要访问的 xtcp 代理的名字
|
||||
server_name = p2p_ssh
|
||||
sk = abcdefg
|
||||
# 绑定本地端口用于访问 ssh 服务
|
||||
bind_addr = 127.0.0.1
|
||||
bind_port = 6000
|
||||
```
|
||||
|
||||
4. 通过 ssh 访问内网机器，假设用户名为 test:
|
||||
|
||||
`ssh -oPort=6000 test@127.0.0.1`
|
||||
|
||||
### 通过 frpc 所在机器访问外网

||||

||||
