This is an early MVP.
- port unmaintained gSTM to golang to make it work across multiple platforms
- have quick overview of active tunnels
- use remote configs (e.g., from github) quickly across multiple platforms
- depless -> not even ssh itself is required
- potentially hook up with vault to use temporary ssh key
go get github.com/gesundheitscloud/goSTM
There is currently a bug with the libui_linux_amd64.a file, which makes the setup slightly more compicated. Get ui via go get and libui manually (without go get):
go get github.com/andlabs/ui ## This will throw an error, but thats ok
mkdir $GOPATH/src/github.com/andlabs
cd $GOPATH/src/github.com/andlabs
git clone https://github.com/andlabs/libui
cd libui
git checkout 3.5alpha ## There is currently a bug on latest master .. See https://github.com/andlabs/ui/issues/230#issuecomment-289231075
make ## Might throw some errors, but thats fine
cp out/libui.a $GOPATH/src/github.com/andlabs/ui/libui_linux_amd64.a
cd ${GOPATH}/src/github.com/andlabs/ui/
go build
The following golang ssh parser is used. ssh_config.
Documentation can be found here godoc.
The SSH tunnel in the ssh_tunnel.go file is inspired by this gist post
The SSH tunnel is implemented like this.
- open local port and wait for connections
- open fork for incoming connections on the local port (ssh config 'LocalForward' bind address and port)
- this fork opens a SSH remote connection to the ssh host (ssh config 'Hostname')
- open a remote connection on that SSH remote connection to the target host (ssh config 'LocalForward' host and hostport)
