Constants ¶
const ( // HTTPS is https prefix HTTPS = "https" // WSS is secure web sockets prefix WSS = "wss" )
const APIVersion = "v1"
Version is a current webapi version
const CurrentProfileSymlink = "profile"
CurrentProfileSymlink is a filename which is a symlink to the current profile, usually something like this:
~/.tsh/profile -> ~/.tsh/staging.yaml
const (
// Directory location where tsh profiles (and session keys) are stored
ProfileDir = ".tsh"
)
const (
ProfileMakeCurrent = 1 << iota
)
Variables ¶
This section is empty.
Functions ¶
func FullProfilePath ¶ added in v1.2.6
FullProfilePath returns the full path to the user profile directory. If the parameter is empty, it returns expanded "~/.tsh", otherwise returns its unmodified parameter

func NewInsecureWebClient ¶

Types ¶
type CertAuthMethod ¶
type CertAuthMethod struct { ssh.AuthMethod Cert ssh.Signer }
CertAuthMethod is a wrapper around ssh.Signer (certificate signer) object. CertAuthMethod then implements ssh.Authmethod interface around this one certificate signer.
We need this wrapper because Golang's SSH library's unfortunate API design. It uses callbacks with 'authMethod' interfaces and without this wrapper it is impossible to tell which certificate an 'authMethod' passed via a callback had succeeded authenticating with.
type ClientProfile ¶ added in v1.2.6
type ClientProfile struct { // // proxy configuration // ProxyHost string `yaml:"proxy_host,omitempty"` ProxySSHPort int `yaml:"proxy_port,omitempty"` ProxyWebPort int `yaml:"proxy_web_port,omitempty"` // // auth/identity // Username string `yaml:"user,omitempty"` // AuthType (like "google") AuthType string `yaml:"auth_type,omitempty"` // SiteName is equivalient to --cluster argument SiteName string `yaml:"cluster,omitempty"` // // other stuff // ForwardedPorts []string `yaml:"forward_ports,omitempty"` }

This is used by external programs linking // against Teleport client and obtaining credentials from elsewhere. SkipLocalAuth bool // AuthMethods are used to login into the cluster. If specified, the client will // use them in addition to certs stored in its local agent (from disk) AuthMethods []ssh.AuthMethod // DefaultPrincipal determines the default SSH username (principal) the client should be using // when connecting to auth/proxy servers. Usually it's returned with a certificate, // but this variables provides a default (used by the web-based terminal client) DefaultPrincipal string Stdout io.Writer Stderr io.Writer Stdin io.Reader // ExitStatus carries the returned value (exit status) of the remote // process execution (via SSh exec) ExitStatus int // SiteName specifies site to execute operation, // if omitted, first available site will be selected SiteName string // Locally forwarded ports (parameters to -L ssh flag) LocalForwardPorts ForwardedPorts // HostKeyCallback will be called to check host keys of the remote // node, if not specified will be using CheckHostSignature function // that uses local cache to validate hosts HostKeyCallback HostKeyCallback // SecondFactorType indicates whether OTP, OIDC or U2F should be used // for the second factor SecondFactorType string // ConnectorID is used to authenticate user via OpenID Connect // registered connector ConnectorID string // KeyDir defines where temporary session keys will be stored. // if empty, they'll go to ~/.tsh KeysDir string // Env is a map of environmnent variables to send when opening session Env map[string]string // Interactive, when set to true, tells tsh to launch a remote command // in interactive mode, i.e. attaching the temrinal to it Interactive bool // ClientAddr (if set) specifies the true client IP.

Key describes a complete (signed) client key
func (*Key) AsAgentKeys ¶
AsAgentKeys converts client.Key struct to a []*agent.AddedKey. All elements of the []*agent.AddedKey slice need to be loaded into the agent!
This is done because OpenSSH clients older than OpenSSH 7.3/7.3p1 (2016-08-01) have a bug in how they use certificates that have been loaded in an agent. Specifically when you add a certificate to an agent, you can't just embed the private key within the certificate, you have to add the certificate and private key to the agent separately. Teleport works around this behavior to ensure OpenSSH interoperability.
For more details see the following: https://bugzilla.mindrot.org/show_bug.cgi?id=2550
