data RootLogin Source


RootLogin Bool

allow or prevent root login


disable password authentication for root, while allowing other authentication methods


allow root login with public-key authentication, but only if a forced command has been specified for the public key

noPasswords :: Property NoInfo Source

Configure ssh to not allow password logins.

To prevent lock-out, this is done only once root's authorized_keys is in place.

authorizedKey :: User -> String -> Property NoInfo Source

Ensures that a user's authorized_keys contains a line. Any other lines in the file are preserved as-is.

randomHostKeys :: Property NoInfo Source

Blows away existing host keys and make new ones. Useful for systems installed from an image that might reuse host keys. A flag file is used to only ever do this once.

hostKeys :: IsContext c => c -> [(SshKeyType, PubKeyText)] -> Property HasInfo Source

Installs the specified list of ssh host keys.

The corresponding private keys come from the privdata.

Any host keys that are not in the list are removed from the host.

hostKey :: IsContext c => c -> SshKeyType -> PubKeyText -> Property HasInfo Source

Installs a single ssh host key of a particular type.

The public key is provided to this function; the private key comes from the privdata;

pubKey :: SshKeyType -> PubKeyText -> Property HasInfo Source

Indicates the host key that is used by a Host, but does not actually configure the host to use it. Normally this does not need to be used; use hostKey instead.

keyImported :: IsContext c => SshKeyType -> User -> c -> Property HasInfo Source

Sets up a user with a ssh private key and public key pair from the PrivData.

If the user already has a private/public key, it is left unchanged.

keyImported' :: IsContext c => Maybe FilePath -> SshKeyType -> User -> c -> Property HasInfo Source

A file can be speficied to write the key to somewhere other than usual. Allows a user to have multiple keys for different roles.

knownHost :: [Host] -> HostName -> User -> Property NoInfo Source

Puts some host's ssh public key(s), as set using pubKey or hostKey into the known_hosts file for a user.

authorizedKeys :: IsContext c => User -> c -> Property HasInfo Source

Makes a user have authorized_keys from the PrivData

This removes any other lines from the file.

listenPort :: Int -> RevertableProperty Source

Makes the ssh server listen on a given port, in addition to any other ports it is configured to listen on.

Revert to prevent it listening on a particular port.
