Hi, FTP working fine, but SFTP gives me issues.

I am able to initiate an SFTP connection to my test server using WinSCP or WsFTPpro.

Using JaSFTP I get this:

this is the first time we've seen this reported. we will forward this error to our 3rd party sftp api vendor and get back to you.

what version of JaSFtp are you using?
which is your test SFTP server type? linux box or ... etc...

Hi, I'm using JaSFTP 7.38.

The test server is a Solaris 9 box.

Thx

Hi, I need to make this SFTP transfer fairly quickly, did you get my .zip file by email? Any progress?

Thx

Robert · Site Admin Joined: 25 May 2006 Posts: 1140

Yes, we did receive your support files. We have forwarded them to our 3rd party sftp api provider. We will email you when they respond to us.

Hi, my deadline to choose a solution has arrived.

Any development on this issue?

Thx

We have released a second SFTP module (based on another 3rd party api) for such situations where our first 3rd party api has issues with SFTP server x etc..

This is a private module in 7.x, and will be publicly released in 8.x. Send us an email and we will send you instructions on how to activate it.

Hi, with this module I get a little further.

The task runs and tells me to look at the log.

In the output log:

From your logs:
1) Remote Host Identification = SSH-1.5-1.2.31
2) com.jscape.inet.sftp.SftpException: incompatible protocol versions: 2.0/1.5

i.e. - Seems like the SSH/SFTP Server is not setup for SSH version 2.

In maverick (regular SFTP) try the following:
Profile settings
Connection tab
SSH context - select SSH1
save the setting and try again..

But the better solution is to have your SFTP admin configure the server to support SSH2

Winscp is still able to connect to my server using SSH1.

We have no idea why you are having issues with both sftp api's. We have users who have no problem with solaris servers. Unfortunately there is not much we can do within our code as the sftp connection is done via our 3rd party sftp api's.

have you tried to configure your sftp server to use SSH2?
