Package ssh 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.
|
|
|
|
You should be able to build any SSH server using only this package, which wraps
|
|
relevant types and some functions from crypto/ssh. However, you still need to
|
|
use crypto/ssh for building SSH clients.
|
|
|
|
ListenAndServe starts an SSH server with a given address, handler, and options. The
|
|
handler is usually nil, which means to use DefaultHandler. Handle sets DefaultHandler:
|
|
|
|
ssh.Handle(func(s ssh.Session) {
|
|
io.WriteString(s, "Hello world\n")
|
|
})
|
|
|
|
log.Fatal(ssh.ListenAndServe(":2222", nil))
|
|
|
|
If you don't specify a host key, it will generate one every time. This is convenient
|
|
except you'll have to deal with clients being confused that the host key is different.
|
|
It's a better idea to generate or point to an existing key on your system:
|
|
|
|
log.Fatal(ssh.ListenAndServe(":2222", nil, ssh.HostKeyFile("/Users/progrium/.ssh/id_rsa")))
|
|
|
|
Although all options have functional option helpers, another way to control the
|
|
server's behavior is by creating a custom Server:
|
|
|
|
s := &ssh.Server{
|
|
Addr: ":2222",
|
|
Handler: sessionHandler,
|
|
PublicKeyHandler: authHandler,
|
|
}
|
|
s.AddHostKey(hostKeySigner)
|
|
|
|
log.Fatal(s.ListenAndServe())
|
|
|
|
This package automatically handles basic SSH requests like setting environment
|
|
variables, requesting PTY, and changing window size. These requests are
|
|
processed, responded to, and any relevant state is updated. This state is then
|
|
exposed to you via the Session interface.
|
|
|
|
The one big feature missing from the Session abstraction is signals. This was
|
|
started, but not completed. Pull Requests welcome!
