But to realize the full functionality of the Bitvise SSH Server, the Bitvise SSH Client is the best client companion that you can use. The Bitvise SSH Client is free to use, whether personal or in an organization.
If you are an organization using Chocolatey, we want your experience to be fully reliable. Due to the nature of this publicly offered repository, reliability cannot be guaranteed. Packages offered here are subject to distribution rights, which means they may need to reach out further to the internet to the official locations to download files at runtime.
To successfully resume TLS on the data connection, your TLS implementation must support a TLS resume mechanism which is compatible with Microsoft Schannel. This is currently a resume that reuses the session ID in the ClientHello. (The other mechanism is the TLS "session_ticket" extension. Schannel currently supports this as client, but not as server.)
The client might be configured with the full public key, or several public keys, corresponding to host keys used by the server. When the client connects, it verifies that the server is using one of these host keys.
When a Windows account user logs in, Bitvise SSH Server will impersonate the security context of that Windows account throughout the user's SSH session. Under default settings, the server will allow any successfully logged on user to take any action that the user is permitted by Windows and file system permissions. Such actions include accessing the terminal shell, running a program, uploading and downloading files, or connecting to another machine using SSH port forwarding.
In the I_SFS_TRANSFER_FILE event, the download and upload attributes attempt to categorize if the client interacted with the file in a way that can be considered a download, an upload, or both. In the above examples:
If the SSH client is set up to try Kerberos authentication, but Kerberos isn't available between the client and the server, the client might hang when it tries to unsuccessfully get Kerberos credentials.
The only performance parameter the SFTP server has control over is its own SSH channel receive window size. However, this only affects the speed of uploads - not downloads - and Bitvise SSH Server is already aggressive in this regard; it's unlikely to bottleneck the client.
The client could avoid the preliminary requests if it were to assume outright that the server supports public key authentication, and that the server will accept the public key the client is trying to use. In this case, the client can just send the full public key request directly, as its first authentication request.
If the client's IP addresses are not predictable, you may need to increase the setting IP blocking > Total threshold. When a client starts an authentication attempt, the SSH Server gives the client a temporary, lightweight penalty. This counts toward the Total threshold setting, and is reset if the client authenticates successfully. But if the client makes hundreds of simultaneous connections, the Total threshold can be exceeded before any authentication attempt succeeds. 2b1af7f3a8
