# Sharing TCP and UDP Servers
|
|
|
|
`zrok` includes support for sharing low-level TCP and UDP network resources using the `tcpTunnel` and `udpTunnel` backend modes.
|
|
|
|
As of version `v0.4`, `zrok` supports sharing TCP and UDP network resources using `private` sharing.
|
|
|
|
To share a raw network resource using `zrok`, you'll want to use the `zrok share private` command from your `enable`-d environment, like this:
|
|
|
|
```
|
|
$ zrok share private --backend-mode tcpTunnel 192.168.9.1:22
|
|
```
|
|
|
|
This will result in a share client starting, which looks like this:
|
|
|
|
```
|
|
╭───────────────────────────────────────────────────────────╮╭────────────────────╮
|
|
│ access your share with: zrok access private 5adagwfl888k ││[PRIVATE][TCPTUNNEL]│
|
|
╰───────────────────────────────────────────────────────────╯╰────────────────────╯
|
|
╭─────────────────────────────────────────────────────────────────────────────────╮
|
|
│ │
|
|
│ │
|
|
│ │
|
|
│ │
|
|
╰─────────────────────────────────────────────────────────────────────────────────╯
|
|
```
|
|
|
|
Then on the system where you want to access your shared resource (an SSH endpoint in this case), you'll need an `enable`-d `zrok` environment. Run the following command (shown in the banner at the top of the `zrok share` client above):
|
|
|
|
```
|
|
$ zrok access private 5adagwfl888k
|
|
```
|
|
|
|
This will start an `access` client on this system:
|
|
```
|
|
╭─────────────────────────────────────────────────────────────────────────────────╮
|
|
│ tcp://127.0.0.1:9191 -> 5adagwfl888k │
|
|
╰─────────────────────────────────────────────────────────────────────────────────╯
|
|
╭─────────────────────────────────────────────────────────────────────────────────╮
|
|
│ │
|
|
│ │
|
|
│ │
|
|
│ │
|
|
╰─────────────────────────────────────────────────────────────────────────────────╯
|
|
```
|
|
|
|
The `access` client shows the endpoint at the top where the service can be accessed. In this case, you'll want to connect your SSH client to `127.0.0.1:9191`. We'll just use `nc` (netcat) to access the shared TCP port:
|
|
```
|
|
$ nc 127.0.0.1 9191
|
|
SSH-2.0-OpenSSH_9.2 FreeBSD-openssh-portable-9.2.p1,1
|
|
```
|
|
|
|
And both the `share` client and the `access` client show the traffic:
|
|
|
|
```
|
|

|
|
```
|
|
|
|
Exit the `access` client to remove the local access to the shared TCP port. Exit the `share` client to disable further accesses to the shared resource.
|
|
|
|
For UDP network resources just use the `zrok share private --backend-mode udpTunnel` instead of `tcpTunnel`.
