Functions

func AdminClient

func AdminClient(socket string) (api.AdminServiceClient, error)

func AdminSocketFile

func AdminSocketFile(sessionID string) string

func AuthorizedKeys

func AuthorizedKeys(file string) ([]ssh.PublicKey, error)

func NewPromptingHostKeyCallback

func NewPromptingHostKeyCallback(stdin io.Reader, stdout io.Writer, knownHostsFilename string) (ssh.HostKeyCallback, error)

func Signers

func Signers(privateKeys []string) ([]ssh.Signer, func(), error)

Signers return signers based on the folllowing conditions: If private key is not supplied, it returns signers from SSH agent; If SSH agent returns no signer, it generates a private key and returns the corresponding signer. If private key is supplied, it returns signers from SSH agent with matching private keys and adds priavte keys to SSH agent where possible; If there is an error, it falls back to return signers from files

func SignersFromFiles

func SignersFromFiles(privateKeys []string) ([]ssh.Signer, error)

func SignersFromSSHAgent

func SignersFromSSHAgent(socket string) ([]ssh.Signer, func(), error)

SignersFromSSHAgent returns all signers from SSH agent

func SignersFromSSHAgentForKeys

func SignersFromSSHAgentForKeys(socket string, privateKeys []string) ([]ssh.Signer, func(), error)

SignersFromSSHAgentForKeys retruns signers from SSH agent for matching private keys. It also adds private key to SSH agent where possbile which simulates the behavior of ssh
