SFTP connect

#FTP #Caché

Hello,

I'm trying to upload file to SFTP server.  

I have access to SFTP server . 
My code is bellow 

Try {
Set sftp = ##class(%Net.SSH.Session).%New()

Set sc = sftp.AuthenticateWithUsername(username,password)
if 'sftp.Connect(host){
            Set status = $$$ERROR($$$GeneralError,"Cannot connect to sftp  ")
            Quit       
}

Set sc = sftp.OpenSFTP(.t)

If 'sftp.Disconnect() Write "Failed to logout",!

} Catch ex {
Set status=$$$ERROR($$$GeneralError,$ZE)
Quit
}

The output : $lb(5001,"Cannot connect to sftp "

What i'm doing wrong ?

Docs specify that Connect should come before Authentication.

Try this code:

Try {
    Set ssh = ##class(%Net.SSH.Session).%New()

    Set sc = ssh.Connect(host)
    Write:$$$ISERR(sc) "Connect:", $System.Status.GetErrorText(sc),!
    
    Set sc = ssh.AuthenticateWithUsername(username, password)
    Write:$$$ISERR(sc) "Auth: ", $System.Status.GetErrorText(sc), !
    
    #dim sftp As %Net.SSH.SFTP
    Set sc = ssh.OpenSFTP(.sftp)
    Write:$$$ISERR(sc) "SFTP: ", $System.Status.GetErrorText(sc), !
    
    Set sc = sftp.Dir("/", .contents, , $$$YES)
    Write:$$$ISERR(sc) "Dir: ", $System.Status.GetErrorText(sc), !
    
    Zwrite contents
    
    //If 'sftp.Disconnect() Write "Failed to logout",!

} Catch ex {
    Set sc = ex.AsStatus()
    Write "Exception: ", ex.DisplayString(), !
}

The code bellow works, but still I can't put file to remote server.

#dim sftp As %Net.SSH.SFTP 
    set ssh = ##class(%Net.SSH.Session).%New()
    do ssh.Connect(host)
    do ssh.AuthenticateWithUsername(username,password)
    //open an SFTP session and get that returned by reference
    do ssh.OpenSFTP(.sftp)

    set dir="C:\Registries\MonthlyReports\KARTEL\202004\30\test1.txt"
    set remotePath="sftp://TEST@77.77.33.11/NEW.txt"

   Set sc=sftp.Put(dir,remotePath)

Exception: <UNDEFINED> 9 zuploadTest+34^pgw.task.UploadToFTP.1 sftp

Remote path should be just:

set remotePath="/NEW.txt"

That said, this error

Ошибка '-2147014836': A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.   

looks like you don't have the network connectivity. Have you tried to connect with Putty from the same server as Ensemble?

 method OpenSFTP(ByRef sftp As %Net.SSH.SFTP) as %Status

Open up an SFTP session for SFTP activity.

 ByRef this means that the variable you pass has to be initialized first.

#dim sftp As %Net.SSH.SFTP 

 just binds the object type to variable  sftp but doesn't initialize it.
So it is <UNDEFINED>

Use your  original line instead or in addition to initalize it

Set sftp = ##class(%Net.SSH.Session).%New()
