ssh-proxy

A ssh proxy utils developed by GO

In the current version, it only provides forward proxy functionality

Install

go install github.com/superwhys/ssh-proxy

protobuf generate

sshproxy.proto

protoc sshproxypb/sshproxy.proto --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative --proto_path=.

Usage

It provide two ways to proxy remote port

Direct connect

single

ssh-proxy connect sshHost:sshPort remoteHost:remotePort

You can proxy the specified port of the remote sshHost locally, as in the example above.

multi

ssh-proxy connect sshHost1:sshPort1 remoteHost:remotePort sshHost2:sshPort2 remoteHost:remotePort

You can also proxy multiple different remote ports locally at the same time.

Mesh connect

Available Commands:
  append      Append services to existing mesh
  connect     Build tunnel to set of services
  create      Create a mesh of multiple services
  delete      Delete mesh
  ls          List all mesh services

It provides command like these

Before use this mode, you need to create a mesh.

Before create a mesh, you should has a env config (.ssh-proxy.yaml) like this in you HOME dir

profiles:
  - EnvName: dev
    # you can just one host in this
    # if you provide muti host, it will use the previous host as a jumpers.
    Hosts:
      - HostName: xxx.xxx.xxx.xxx 
      - HostName: yyy.yyy.yyy.yyy
        IdentityFile: ~/.ssh/id_rsa

then, you can create a mesh very simply

ssh-proxy mesh create --env dev mesh-test localhost:8000

and you can connect to mesh like that

ssh-proxy mesh connect mesh-test

GRPC-UI

after you proxy the remote port locally, it will start a grpc server and provide a grpcui debug page,

in this page, there are there command: connect, disconnect, getAllNodes for you to monitor your proxy
