  "remote": "ssh://user@vm.me:22",
  "blocked": [

A simple command to forward all traffic for the given port

# install it: go get github.com/justmao945/mallory/cmd/forward

# all traffic through port 20022 will be forwarded to destination.com:22
forward -network tcp -listen :20022 -forward destination.com:22

# you can ssh to destination:22 through localhost:20022
ssh root@localhost -p 20022

TODO

Docker container

Considering the following config file:

$ cat mallory.json
{
  "id_rsa": "/tmp/id_rsa",
  "local_smart": ":1315",
  "local_normal": ":1316",
  "remote": "ssh://bhenrion@10.151.0.11:22"
}

You can run the container (zoobab/mallory) my mounting the config file, the SSH key, and mapping the 2 ports:

$ docker run -v $PWD/mallory.json:/root/.config/mallory.json -p 1316:1316 -p 1315:1315 -v $PWD/.ssh/id_rsa:/tmp/id_rsa zoobab/mallory

My use case was to connect to a Kubernetes cluster (Openshift) installed behind an SSH bastion:

$ export http_proxy=http://localhost:1316
$ export https_proxy=https://localhost:1316
$ oc login https://master.mycluster.zoobab.com:8443
Authentication required for https://master.mycluster.zoobab.com:8443 (openshift)
