Interface ISftpClient
Implementation of the SSH File Transfer Protocol (SFTP) over SSH.
public interface ISftpClient : IBaseClient, IDisposable
- Inherited Members
Properties
BufferSize
Gets or sets the maximum size of the buffer in bytes.
uint BufferSize { get; set; }
Property Value
- uint
The size of the buffer. The default buffer size is 32768 bytes (32 KB).
Remarks
For write operations, this limits the size of the payload for individual SSH_FXP_WRITE messages. The actual size is always capped at the maximum packet size supported by the peer (minus the size of protocol fields).
For read operations, this controls the size of the payload which is requested from the peer in a SSH_FXP_READ message. The peer will send the requested number of bytes in a SSH_FXP_DATA message, possibly split over multiple SSH_MSG_CHANNEL_DATA messages.
To optimize the size of the SSH packets sent by the peer, the actual requested size will take into account the size of the SSH_FXP_DATA protocol fields.
The size of the each individual SSH_FXP_DATA message is limited to the
local maximum packet size of the channel, which is set to 64 KB
for SSH.NET. However, the peer can limit this even further.
