cmd/coordinator, cmd/buildlet, cmd/gomote: add SSH support This adds an SSH server to farmer.golang.org on port 2222 that proxies SSH connections to users' gomote-created buildlet instances. For example: $ gomote create openbsd-amd64-60 user-bradfitz-openbsd-amd64-60-1 $ gomote ssh user-bradfitz-openbsd-amd64-60-1 Warning: Permanently added '[localhost]:33351' (ECDSA) to the list of known hosts. OpenBSD 6.0 (GENERIC.MP) golang/go#2319: Tue Jul 26 13:00:43 MDT 2016 Welcome to OpenBSD: The proactively secure Unix-like operating system. Please use the sendbug(1) utility to report bugs in the system. Before reporting a bug, please try to reproduce it with the latest version of the code. With bug reports, please try to ensure that enough information to reproduce the problem is enclosed, and if a known fix for it exists, include that as well. $ As before, if the coordinator process is restarted (or crashes, is evicted, etc), all gomote instances die. Not yet supported: * scp (help wanted) * not all host types are configured. most are. some will need slight config tweaks to the Docker image (e.g. adding openssh-server) Supports currently: * linux-amd64 (host type shared by 386, nacl) * linux-arm * linux-arm64 * darwin * freebsd * openbsd * plan9-386 * windows Implementation details: * the ssh server process listens on port 2222 in the coordinator (farmer.golang.org), which is behind a GKE TCP load balancer. * the ssh server library is github.com/gliderlabs/ssh * authentication is done via Github users' public keys. It's assumed that gomote user == github user. But there's a mapping in the code for known exceptions. * we can't give out access to this too widely. too many things are accessible from within the host environment if you look in the right places. Details omitted. But the Go team and other trusted gomote users can use this. * the buildlet binary has a new /connect-ssh handler that acts like a CONNECT request but instead of taking an explicit host:port, just says "give me your machine's SSH connection". The buildlet can also start sshd if needed for the environment. The /connect-ssh handler also installs the coordinator's public key. * a new buildlet client library method "ConnectSSH" hits the /connect-ssh handler and returns a net.Conn. * the coordinator's ssh.Handler is just running the OpenSSH ssh client. * because the OpenSSH ssh child process can't connect to a net.Conn, an emphemeral localhost port is created on the coordinator to proxy between the ssh client and the net.Conn returned by ConnectSSH. * The /connect-ssh handler requires http.Hijacker, which requires fully compliant net.Conn implementations as of Go 1.8. So I needed to flesh out revdial too, testing it with the golang.org/x/net/nettest package. * plan9 doesn't have an ssh server, so we use 0intro's new conterm program (drawterm without GUI support) to connect to plan9 from the coordinator ssh proxy instead of using the OpenSSH ssh client binary. * windows doesn't have an ssh server, so we enable the telnet service and the coordinator ssh proxy uses telnet instead on the backend on the private network. (There is a Windows ssh server but only in new versions.) Happy debugging over ssh!
