Functions

func Lookup

func Lookup(configPath string, key string) ([]string, error)

Lookup key in the effective SSHD config. This doesn't search the config path. Instead it uses sshd -T to get the values of default paramters too.

Types

type Modifier

type Modifier struct {
	ConfigPath string
	// contains filtered or unexported fields
}

Modifier provides a safe wrapper to modify SSHD configuration. Changes are verified before being commited. If verification fails, the original file is restored.

func (*Modifier) Commit

func (s *Modifier) Commit() error

Commit is a function to apply the SSHD config modifications made by Set to config file and test whether the resulting file is valid. The check is performed with 'sshd -t'. If the check fails, then the file is reverted to the original before returning the error.

func (*Modifier) Set

func (s *Modifier) Set(key, value string)

Set adds a key value pair to the SSHD config. It will leave other config lines with the same key and only replace a line if it is exactly the same. Calling this function does not apply the change until Commit is called.

func (*Modifier) SetUnique

func (s *Modifier) SetUnique(key, value string)

SetUnique sets a unique key in the SSHD config. This means that any other use of the key, even with a different value will be replaced. SetUnique expects that there is at most 1 use of the key in the SSHD config (i.e. the key is unique in the existing SSHD config). Calling this function does not apply the change until Commit is called.
