TElIdSSHClient provides client-side functionality for SSH connections.
Description
ElIdSSHClient is used to add SSH support to client side of TCP connection
(the client side is the side which initiates connection).
ElIdSSHClient uses Indy sockets as an underlying transport.
To initiate the connection call
Connect
method.
To transfer the data over the secure SSH connection the
Tunnel objects are used.
Each tunnel represents a type of logical connection ( Shell,
Command,
Subsystem,
TCP-IP local forwarding,
TCP-IP remote forwarding,
X11 forwarding).
The Tunnel object may create a number of
TunnelConnection
class instances. Each TunnelConnection carries single logical connection.
For example, if you want to forward the connections, accepted by
remote port to your machine, you have to create one instance of
TElRemotePortForwardSSHTunnel,
and for each accepted connection on the server side
one instance of
TElSSHTunnelConnection
class will be created.
By default, TElIdSSHClient is allowed to work using both SSH1 and SSH2 versions and
all encryption, public key, key exchange and MAC algorithms. You can disable or
enable some of versions using
Versions
property and disable or enable security properties with
EncryptionAlgorithms,
PublicKeyAlgorithms,
MacAlgorithms,
KexAlgorithms and
CompressionAlgorithms properties.
When connection is established, connection version can be read from
Version
property.
