Functions

func GetDefaultSigner

func GetDefaultSigner() (ssh.Signer, error)

func GetSignerFromFile

func GetSignerFromFile(path string) (ssh.Signer, error)

func MatchPatternList

func MatchPatternList(patterns []*Pattern, input string) bool

MatchPatternList returns true if the input matches any of the patterns in the list. Negated patterns are matched first; if a negated pattern matches, the function returns false immediately. If no patterns match, the function

func ParseAuthorizedKeys

func ParseAuthorizedKeys(b []byte) ([]ssh.PublicKey, error)

func ParseSSHTimespec

func ParseSSHTimespec(value string) (time.Time, error)

func ParseTimePattern

func ParseTimePattern(patt string) (time.Time, time.Time, error)

func RenderTime

func RenderTime(seconds uint64) string

func ShowNotification

func ShowNotification(message string)

	Comment     string   `json:"comment"`
}

func (*MarshalledAllowedSigner) Unmarshal

func (m *MarshalledAllowedSigner) Unmarshal() (AllowedSigner, error)

type Pattern

type Pattern struct {
	// contains filtered or unexported fields
}

Pattern is a pattern in a Host declaration. Patterns are read-only values; create a new one with NewPattern().

func NewPattern

func NewPattern(s string) (*Pattern, error)

NewPattern creates a new Pattern for matching hosts. NewPattern("*") creates a Pattern that matches all hosts.

From the manpage, a pattern consists of zero or more non-whitespace characters, `*' (a wildcard that matches zero or more characters), or `?' (a wildcard that matches exactly one character). For example, to specify a set of declarations for any host in the ".co.uk" set of domains, the following pattern could be used:

Host *.co.uk

The following pattern would match any host in the 192.168.0.[0-9] network range:

Host 192.168.0.?

func (Pattern) String

func (p Pattern) String() string

String prints the string representation of the pattern.
