Variants

CouldNotReadKey

The key file could not be parsed.

KexInit

Unspecified problem with the beginning of key exchange.

UnknownAlgo

Unknown algorithm name.

NoCommonAlgo

No common algorithm found during key exchange.

Fields

kind: AlgorithmKind

ours: Vec<String>

theirs: Vec<String>

Version

Invalid SSH version string.

Kex

Error during key exchange.

PacketAuth

Invalid packet authentication code.

Inconsistent

The protocol is in an inconsistent state.

NotAuthenticated

The client is not yet authenticated.

UnsupportedAuthMethod

The client has presented an unsupported authentication method.

IndexOutOfBounds

Index out of bounds.

UnknownKey

Unknown server key.

WrongServerSig

The server provided a wrong signature.

PacketSize(usize)

Excessive packet size.

WrongChannel

Message received/sent on unopened channel.

ChannelOpenFailure(ChannelOpenFailure)

Server refused to open a channel.

Disconnect

Disconnected

NoHomeDir

No home directory found when trying to learn new host key.

KeyChanged

Remote key changed, this could mean a man-in-the-middle attack is being performed on the connection.

Fields

line: usize

HUP

Connection closed by the remote side.

ConnectionTimeout

Connection timeout.

KeepaliveTimeout

Keepalive timeout.

InactivityTimeout

Inactivity timeout.

NoAuthMethod

Missing authentication method.

SendError

Pending

DecryptionError

RequestDenied

Keys(Error)

IO(Error)

Utf8(Utf8Error)

Compress(CompressError)

Decompress(DecompressError)

Join(JoinError)

Elapsed(Elapsed)

StrictKeyExchangeViolation

Fields

message_type: u8

sequence_number: usize

Signature(Error)

SshKey(Error)

SshEncoding(Error)

InvalidConfig(String)

RecvError

This error occurs when the channel is closed and there are no remaining messages in the channel buffer. This is common in SSH-Agent, for example when the Agent client directly rejects an authorization request.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
