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! |
