Re: Session open with tunneling

I tried V5.1.2, but nothing changed yet.

Are you sure the needed key is "TunnelHostKey" ? Did I misunderstand or else ?
I can't understand what was happen.

sOs.AddRawSettings("TunnelHostKey", "ssh-rsa 2048 7e:c8:9e:c7:7a:26:54:c0:65:5a:13:14:36:2f:cf:7c");

If you have something difficult to solve this issue, would you give me another solution ? For example, can you modify the program to auto-accept hostkeys ?
Or would you reveal the source code ?

};



using (Session session = new Session())

{

    sOs.AddRawSettings("TunnelHostKey", "ssh-rsa 2048 7e:c8:9e:c7:7a:26:54:c0:65:5a:13:14:36:2f:cf:7c");

    sOs.AddRawSettings("Tunnel", "1");

    sOs.AddRawSettings("TunnelHostName", "<TUNNELHOST>.jp");

    sOs.AddRawSettings("TunnelPortNumber", "22222");

    sOs.AddRawSettings("TunnelUserName", "<TUNNELUSER>");

    sOs.AddRawSettings("TunnelPublicKeyFile", @"I:\My Docs\privkey.ppk");

I received these at Date: Sat, 03 Nov 2012 08:25:35 +0100(mail header) and there are nothing newer.

I attached a debug log. In it,

TunnelHostKey seemed to not be processed by the right way in the program.
My understanding is that TunnleHostKey is set into the cache when I set it by rawSettings.
Is that right ? If so, the message in debug log seemed a little bit strange.

In addition, I tried to repeat with AddRowSettings deleted and got the quite same result.

I guess 'TunnelHostKey' was ignored. Perhaps same as 'HostKey' and 'SshHostKey'.

Re: Session open with tunneling

Use SessionOptions.SshHostKeyFingerprint to set you main session host key fingerprint and SessionOptions.AddRawSettings("TunnelHostKey", ...) to set the tunnel session host key fingerprint.

Fingerprint's in the Error message was the one for Tunnel server's.

My code is like this :

SessionOptions sOs = new SessionOptions 

{ 

    Protocol = Protocol.Sftp, 

    HostName = "<MyServerFQDN>", 

    PortNumber = <Port>, 

    UserName = "<UserName>",

    sOs.AddRawSettings("TunnelUserName", "<TunnelUser>"); 

    sOs.AddRawSettings("TunnelPublicKeyFile", "<TunnelUser'sPPK>");

}

I guess somewhere of authentication process of tunnel server's fingerprint may not good to work.
In addition, it also did not work when I changed the fingerprints' order. (same error message)

Re: Session open with tunneling

Just set SessionOptions.SshHostKeyFingerprint to any valid value to circumvent the check. The raw settings overrides its value anyway.

Anyway, I've sent you an email with link a to a dev version that fixes your issue.
Let me know.

Re: Session open with tunneling

But unfortunately I tried to set by AddRawSettings but It didn't work.

    HostName = "<MyServerFQDN>", 
    PortNumber = <Port>,

What should I do else?

One confirmation, I use the form of ssh-rsa 2048 xx:xx:xx:.....:xx as my fingerprints format when I set them by AddRawSettings, is it correct?
(I wonder if 'Raw' means the exact way in winscp.ini strings)

Thanks

Re: Session open with tunneling

2012-10-25

Ok, this might be tricky.

Point is that you need to add both fingerprints to the SshHostKeyFingerprint, separated by semicolon.

But the current validation rules prevents you doing that.
You can circumvent that by using:

AddRawSettings("HostKey", "hostkey1;hostkey2")

Let me know.

    Password = "<PassWd>",
    SshHostKeyFingerprint = "<MyServer'sFingerPrint>"
};
 
using (Session session = new Session())
{
    // Connect
    sOs.AddRawSettings("Tunnel", "1");
    sOs.AddRawSettings("TunnelHostName", "<MyTunnelServer");
    sOs.AddRawSettings("TunnelPortNumber", "<TunnelPort>");
    sOs.AddRawSettings("TunnelUserName", "<TunnelUser>");
    sOs.AddRawSettings("TunnelPublicKeyFile", "<TunnelUser'sPPK>");
    session.Open(sOs);
}

But I got an Error message like this :

Error: WinSCP.SessionRemoteException: Host key wasn't verified! ---> WinSCP.SessionRemoteException: Host key fingerprint is <Tunnel Server's Fingerprint>
Authentication failed.

I cannot understand how to set the tunnel server's fingerprint. I guess it may exist in the [SshHostKeys] section in the WinSCP.ini file, but I could not use it.

Would you tell me how to set tunnel server's fingerprint? Or is there any other workaround?

Thanks!
