API 1 FTPS with MBS CURLSMBS

[Fred_Stephenson]

I finally managed to get the accounting software company to set up FTPS, however now I have the following problem, see test code below
var cmbs as new CURLSMBS
// s is a string parameter when calling the method with windowsansi encoding
var i as integer
if not DebugBuild then

var fwp as new XojoCloud.FirewallPort(990,xojocloud.FirewallPort.Direction.Outgoing)
fwp.open
if fwp.isopen then

// get following from Grunndata
cmbs.OptionURL=ftpaddress
cmbs.OptionUsername=ftpuser
cmbs.OptionPassword=ftppass

cmbs.SetInputData(s)
cmbs.OptionAppend=true
cmbs.OptionUpload=true
//cmbs.OptionLocalPortRange=2
cmbs.OptionPort=990
//cmbs.OptionTransferText=True
var i as integer =cmbs.Perform
if i <> 0 then
  MsgBox (cmbs.DebugData+endofline)
  return
end if
var bb as boolean
MsgBox (cmbs.DebugData)

else

end if

else
// get following from Grunndata
cmbs.OptionURL=ftpaddress
cmbs.OptionUsername=ftpuser
cmbs.OptionPassword=ftppass
cmbs.SetInputData(s)
cmbs.OptionAppend=true
cmbs.OptionUpload=true
cmbs.OptionTransferText=True

cmbs.OptionPort=990
i =cmbs.Perform
MsgBox (cmbs.DebugData)
var bb as boolean

end if

My problem is the OptionTransferText. If I use that on XojoCloud the app just shuts down.
I know the FTPS server accepts the data because it works when I debug locally - that is to say the data arrives and is written to the FTPS Server.
If I just send withoutthe option defined then the text arrives as UTF8 and their import routine requires windowsansi… Note I do send as windowsansi

Are you sure it’s FTPS and not FTPS?

Any crash reports seen?
For FTP you may need two ports, so 990 plus some other one.

[Fred_Stephenson]

Christian,
Yes it’s FTPS. As I said it runs fine locally on my developer machine.
Maybe a stupid question but where would I find a crash report on XojoCloud. All I get in the browser is

[Fred_Stephenson]

It just ran twice and then stalled the third time, so it seems to function intermittently

[Christian_Schmitz]

You may ask @Jason_Parsley or hello@xojo.com for support on crash reports.

SFTP needs only one port.
FTPS needs two ports, one data and one command connection.
And you may need to use OptionFTPPort to tell the server what port you opened for data connection.

[Fred_Stephenson]

Christian,
thanks that seems to have done the trick.
I opened port 991 as well
set OptionFTPPort="-:990-991"
and so far everything works.
If ever I come back up to Koblenz I’ll make sure to bring another box of wine

[Christian_Schmitz]

Let me know when you are in the area.

[Fred_Stephenson]

Actually that didn’t fix it… I’ll take a break on this and come back to it later. I’ll still bring the wine if ever

@Fred_Stephenson

var fwp as new XojoCloud.FirewallPort(990,xojocloud.FirewallPort.Direction.Outgoing)
fwp.open

This isn’t going to work if your transfer code is asynchronous because when fwp goes out of scope, the port will close.

I suggest putting an array of FirewallPorts somewhere and storing references to them until you are sure you are done with them.

[Fred_Stephenson]

Hi Greg,
Thanks.
I tried an array, but in the method. I’ll make it a property of the webpage and see if that does the trick.

[Greg_O_Lone]

If you’re using them a lot, just put them on App and open them when the app launches. That’ll save you a lot of headaches.

[Fred_Stephenson]

Ok, I have opened 100 outgoing ports (65000 to 65100)
I get a connection on 990 and everything is fine until the following from the debuglog

Sorry I’m stumped!
Is the FTPS server expecting the incoming port to be open on 65000?

[Christian_Schmitz]

Could you switch to SFTP and avoid this trouble?

[Fred_Stephenson]

Christian,
If I could I would. I am not in control, it’s my client’s accounting package company. I asked them to change their FTP to SFTP or FTPS. They finally changed to FTPS.

[Christian_Schmitz]

So it is waiting on incoming connection on port 65000.

You did use XojoCloud.FirewallPort with direction XojoCloud.FirewallPort.Direction.Incoming for port 65000?

[Fred_Stephenson]

In that test I had it as outgoing…
I just tried it with incoming and I am pleased to say that, but very cautiously, it seems to have worked.
I need to give it a real good testing now.
Thanks for all the patience and help.
