SSH.NET 2014.4.6-beta2

2014.4.6-beta2 ============== New Features: * Improved accuracy of IsConnected on .NET * Added support for ssh.com (SSH-2) private keys (issue #1987) * Support an acceptable group of up to 8192 bits for SHA-1 and SHA-256 Diffie-Hellman Group and Key Exchange (issues #1973 and #1777) Changes: * Reduced default buffer size for SftpClient from 64 KB to 32 KB as some SSH servers apply a hard limit of 64 KB at the transport level. Fixes: * SftpClient is throwing undocumented exceptions (issue #2148) * Client channels are no longer closed on dispose (issue #1943) * SftpClient.Exists(string) returns true for a path that does not exist (issues #1952, #1696 and #1574) * ObjectDisposedException when channel is closing (issues #1942 and #1944) * Stack overflow during authentication when server returns same allowed methods after partial success (issue #2399) * SshCommand doesn't cleanup subscribed events (issue #2295) * Lines before protocol identification string are not skipped (issue #1935 and #2223) * ShellStream.ReadLine produces incorrect output when reading multi-byte characters (issue #2190) * SftpClient constructor throws ArgumentException when host contains underscore (issue #1845) * Signing key is missing from source download (issue #2455) * Forwarded Port channels can get stuck waiting (issue #1558) * NullReferenceException when SftpFileStream is finalized after dispose of session (issue #2013) * BlockCipher.Encrypt fails if input message is not padded (issue #2547) * ScpClient: Missing files when using DirectoryUpload (issue #1382) * Dynamic port forwarding slows down to a crawl (issue #2010) * SendKeepAlive causes SocketException when connection is dropped (issue #2029) * SocketException on Dispose or Disconnect (issue #2400) * Sending EOF on wrong channel number (issue #1877) * ForwardedPortDynamic: Unhandled exception if client terminates socket (issue #1844) 2014.4.6-beta1 ============== New Features: * Added callbacks to UploadFile, DownloadFile and ListDirectory in SftpClient (issue #1324) * Allow a given private key file to be used concurrently * Performance improvements: - optimization of payload size for both read and write operations (SftpClient only) - increase window size from 1MB to 2MB - increase buffer size from 16KB to 64KB for SftpClient - take into account the maximum remote packet size of the channel for write operations - increase maximum size of packets that we can receive from 32 KB to 64 KB * Improve exception message for authentication failures Breaking changes: * Assembly name is now Renci.SshNet for all supported frameworks * The Renci.SshNet assemblies for .NET and Silverlight are now strong-named (issue #1802) Fixes: * Incorrect copyright in assemblies (issue #1764) * Remove linefeed from WriteLine method in Shellstream class (issue #1584) * Disable logging of messages in release builds (issue #1767) * Stuck loop on key exchange using arcfour encryption (issue #1922) * Timeout sending data to server with low window size (issue #1706) * No connection possible with the same auth method requested multiple times (issue #1930) * Unobserved exception rethrown by finalizer thread (issue #1298 and #1587) * Client cipher is used to decrypt server messages (issue #1917) * Connection dropped by server due to invalid DSA signature (issue #1918) * Correct casing of Security/Cryptography/HMAC.cs to fix build on Linux (issue #1505) * HTTP proxy hangs (issue #1890) * Wrong parameters to SetSocketOption leads to SocketException under Mono (issue #1799) * Incorrect check for timeout values (issue #1620) * Wrong PKCS7 padding in DES algorithm (issue #1580) * OverflowException on empty server response (issue #1562) * Event handle leak (issue #1761) * SftpFileStream is very slow (issue #1919) * Write access required for private key file
