Re: sftp Version 4

What 'sftp' version are you taling about?  There are SSH protocols version 1 & 2.  There is no protocol version 4 that I am aware of.

 

If you are taling about the SSH package itself then the latest version of the Secure Shell package from HP is A.05.90.

 

HP Secure Shell software is available from:

Re: sftp Version 4

Hi Steven .

 

Thanks for the link.

 

I try to understand the story but I cannot.

 

Is there a Version 4 protocol or not ?

 

And if so do our OpenSSh supports protocol 4?

 

Which is available at software.hp.com.

 

Kind regards

Re: sftp Version 4

The protocol specification for sftp protocol version 4 exists, but it has not yet been implemented in OpenSSH. And as HP Secure Shell at software.hp.com (HP product T1471AA) is based on OpenSSH, it does not have support for sftp v4 either.

 

The question is, do you need a SFTP v4 client, a SFTP v4 server, or both?

(Do you need the capability to initiate SFTP connections, or to act as a server for some other SFTP client software? Or both?)

 

According to this link posted by Steven, there are some options for both, but you may have to compile it from source code and/or do some (hopefully minor) porting:

http://www.greenend.org.uk/rjk/sftp/sftpimpls.html

  • LFTP might be an OK command-line SFTP v4 client. Since it's command-line, it should not have too much dependencies and should be very scriptable if you need to automate it.
  • On the server side, ProFTPD + mod_sftp might be an acceptable server package, and the basic ProFTPD is available as a pre-built binary from the Porting Archive, so you might only need to compile the mod_sftp module: http://hpux.connect.org.uk/hppd/hpux/Networking/FTP/proftpd-1.3.4a/
  • The Green End SFTP server is apparently designed as a drop-in replacement for the OpenSSH sftp-server binary, so it might be easy to replace the standard /opt/ssh/libexec/sftp-server binary of the HP SSH package with it. But it looks like it might not be exactly production quality...

Re: sftp Version 4

This might be more simply addressed by giving the exact requirement from Oracle that says you need SFTP version 4.  I have and do support a lot Oracle running on HP-UX and have never ran into this requirement. What is it your looking at? Do you have a link or application document that you are looking at?

Re: sftp Version 4

We need SFTP Server v4. The client is Oracle Fusion Middleware which is already running on 4.

Please let us know whether it is feasible or not.... as it is a strict requirement.

Re: sftp Version 4

Hi Wim,

 

I do understand that its a requirement, but can you connect us to the stated requirement?  Give a link to the document your reading the requirement in. If they distribute their product for HP-UX installation, then I'm sure there is an acceptable solution for their requirements. But without being able to see the requirements we're all just shooting in the dark on what the solution is.
