I need to upload some files to a server that only understands Sftp SSH-1.
Before asking the question, an update to SSH-2 is not possible.Crying or Very sad

I can connect to the server successfully with the desktop tool of WinSCP if I
choose the preferred SSH version 1, but how I do it via .Net.Question

When running the code below I get the exception "Incoming packet was garbled on decryption"

Thanks in advance.

Source code:

SessionOptions sessionOptions = new SessionOptions
Protocol = Protocol.Sftp,
HostName = "",
PortNumber = 22,
UserName = "root",
Password = "xxxxxxxxxxx",
SshHostKeyFingerprint = null,

using (WinSCP.Session session = new WinSCP.Session())
// Connect
session.DefaultConfiguration = false;

After I have experimented a lot, I have it figured out:

sessionOptions.AddRawSettings("Compression", "0");
sessionOptions.AddRawSettings("SshProt", "1");

Nevertheless thanks.Mr. Green
