Golang library to proxy ssh connections

Why

I'm using this library in a honeypot, using this library I can intercept the ssh connections and connect each connection to their own container. Sessions can be recorder using the TypeWriterReadCloser.

Use cases

• capture the flag
• honeypots
• creating screencasts
• whatever you'd like

Example

go run examples/main.go --dest 172.16.84.182:22 --key examples/conf/id_rsa

Screencast of recorded session:

sshproxy's Issues

Session recording with TypeWriterReadCloser

I am trying to record session with TypeWriterReadCloser but I am novice yet when golang comes towards interfaces :) , here you can see how I tried but no success. Scanner consume the reader so the proxy client do not receives any response. I have also tried to go with TeeReader but it does not implement Closer method. You can put some stuff how I could record? Thanks in advance :)

Input_userauth_errorr on handshake

Not every time but atleast 3 times out of 10 proxy shows this error to client on handshake thus results to fail: input_userauth_error: bad message during authentication: type 20 . I have tried but I could not catch this. Please have a look
