ConnectedEvent (wodSFTP / wodSFTP.NET / wodSFTPdll)

Hi,

can someone tell me how I use the sftp1.ConnectedEvent?
I need an Code-Example, the Example
Sftp1.ConnectedEvent += new WeOnlyDo.Client.SFTP.ConnectedDelegate(Sftp1_Connected); doesn't work...

Thanks.

Hi Paul,

Did you maybe try our samples which comes with wodSFTP.NET? You can find it in component Samples folder. We have samples for C# and in samples Events are implemented.

Basically you should type: Sftp1.ConnectedEvent += and hit tab key twice and Event will be created.

Let us know how it goes.

Hi,

thanks! Now it works

delegate void ConnectedEventCallback(object Sender, WeOnlyDo.Client.SFTP.ConnectedArgs Args);

private void sftp1_ConnectedEvent(object Sender, WeOnlyDo.Client.SFTP.ConnectedArgs Args)
{
if (this.textBox2.InvokeRequired)
{
ConnectedEventCallback d = new ConnectedEventCallback (sftp1_ConnectedEvent);
this.Invoke(d, new object[] { Sender, Args });
}
else
{if (Args.Error == null)
{
textBox1.Text=
***CONNECTED!! ;
}
else
textBox1.Text= Args.Error.Message;
}
}

Now I get the information, that a connection can not established
It works with WinSCP... Protocol-extract:

Hi Paul,

Are you using proxy for connecting to web? From the WinSCP log i see that you use proxy to connect.

Please connect Proxy settings for wodSFTP.Net before connecting. It should work afterwards. you need to set ProxyType, ProxyHostname, ProxyPort and ProxyLogin and ProxyPassword properties (if your proxy requires authentication).

Can you try please?

Regards,
Damba

This is my Code, do you see any Problems?

sftp1 = new SFTP();
this.sftp1.ConnectedEvent += new WeOnlyDo.Client.SFTP.ConnectedDelegate(this.sftp1_ConnectedEvent);
sftp1.ProxyHostname = 180.44.255.130 ;
sftp1.ProxyLogin = XXXX ;
sftp1.ProxyPassword = XXXX ;
sftp1.ProxyPort = 1080;
sftp1.ProxyType = SFTP.ProxyTypes.ProxySocks4;
sftp1.Authentication = SFTP.Authentications.Password;
sftp1.Login = myUser ;
sftp1.Password = XXXX ;
sftp1.Connect( 222.20.146.238 ,22);

Paul,

The code looks ok to me. It still doesn't work?

What error do you receive in Connected Event? Can you please check Args for Error?

Regards,
Damba

The Error-Message is Cannot access a disposed object.
Object name: '.'.

Wrong password or what do you think?

Paul,

Where exactly do you get that error in debugger?

It looks like you're trying to access a proeprty of object that was already destroyed.

Can you try one of our samples with the same settings, do they work?

Regards,
Damba

So I tested it with the Sample-Application . Now the Error-Massage is:
***CONNECTING...
State changed to Connecting
from Disconnected
State changed to Disconnected
from Connecting
Error: Timeout occured due to inactivity

Paul,

Is there any chance we could connect to that server?

If that's possible, you can send any sensitive information to techsupport@weonlydo.com

Also, what server are you connecting to? Can you do Telnet your_server 22 and tell me what the first line returned?

Regards,
Damba

Interested in the outcome of this topic as I'm having the same problem. My code is almost identical to Paul's and I'm using SSH Tectia server. I am not able to provide access to the server in question.

Hi Robert,

First of all, what version of the component are you using?

Can you try connecting there using our sample applications? Does that work?

Do you use Proxy? Did you set the Proxy related properties?

Do you have FireWall on? Can you try disabling it?

Regards,
Damba

I've set blocking = true. When I hit the connect() statement, control goes away and does not return until the connection is closed by the server.

The connection to the server is successful - this is confirmed by reviewing logs on the server - and the server closes the connection on timeout due to no activity.

I'm using version 3.04.20

Robert,

And the ConnectedEvent does trigger?

Can you check the Args.Errorcode? Does it contain value?

Also, are you using any other Events?

Regards,
Damba

The Connected event never fires.

The following events occur:
StateChangedEvent: State changed from Disconnected to Connecting
StateChangedEvent: State changed from Connecting to Disconnected
DisconnectedEvent: Disconnected

The server logs show the following events:
410 Login_success
..
420 Session_channel_open
421 Session_channel_close
412 Logout Idle timeout exceeded. Local disconnect
402 Disconnect. Reason. by Application Idle timeout exceeded. Local disconnect

The timeout value I'm using is 300 but the connection times out after about 2 minutes.

Robert,

Can you please try updating to the latest version and try it out?

Also, you can connect to that server using other clint, i.e. FileZilla?

Regards,
Damba

Damba,

I have uncovered evidence that the problem is not with my client but with the server.

Thanks for your help - I hope I won't need to call on you again!

Regards,
Robert
