Fixes a race where CloseWrite() could be called before Exit(), causing SSH clients (especially on macOS) to miss the exit status. Simplified run() to use sync.WaitGroup and guarantee Exit() is sent before EOF per RFC 4254 section 6.10. Also: - Send SIGHUP instead of SIGKILL on session termination - Use exit code 127 for command not found - Use exit code 255 for SSH permission/protocol errors - Use exit code 254 for recording failures - Complete TCP handlers only after I/O completes Fixes tailscale/tailscale#18256 Signed-off-by: James Tucker <james@tailscale.com>

The Glider Labs SSH server package is dope. —@bradfitz, Go team member
This Go package wraps the crypto/ssh package with a higher-level API for building SSH servers. The goal of the API was to make it as simple as using net/http, so the API is very similar:
package main
import (
"tailscale.com/tempfork/gliderlabs/ssh"
"io"
"log"
)
func main() {
ssh.Handle(func(s ssh.Session) {
io.WriteString(s, "Hello world\n")
})
log.Fatal(ssh.ListenAndServe(":2222", nil))
}
This package was built by @progrium after working on nearly a dozen projects at Glider Labs using SSH and collaborating with @shazow (known for ssh-chat).
Examples
A bunch of great examples are in the _examples directory.

Contributing
Pull requests are welcome! However, since this project is very much about API design, please submit API changes as issues to discuss before submitting PRs.
Also, you can join our Slack to discuss as well.
Roadmap
- Non-session channel handlers
- Cleanup callback API
- 1.0 release
- High-level client?
