SSH2 Transfer from Windows-Server to VMS-Server

I have the following problem. (Transfer Files from a Windows-Server to a VMS-Server with SSH2 and FTP)

The Connection cancels ,if the file is bigger than 29997 Bytes.

The SSH_version of VMS
HV:ENTW>ssh -"V" -"L"ftp/10021:localhost:21 carla_f@10.17.138.98
fase$dkc0:[sys1.syscommon.][sysexe]tcpip$ssh_ssh2.exe: SSH Secure Shell OpenVMS
(V1.0) 2.4.1 on AlphaServer DS15 - VMS V7.3-1

The Windows-2003-Server uses FreeSSH

My Question is: How can I avoid that the Connection cancels or what can I do in customizing SSH

Re: SSH2 Transfer from Windows-Server to VMS-Server

are you up to date with the patches for TCPIP Services for OpenVMS?
Can you post the result of

TCPIP SHOW VERSION

Hi Steudel

First of all, welcome to OpenVMS Forum.

older SSH Version have different problems, with file formats and also size of files. We experienced many funny problems with those older versions.

I would recommend to upgrade the Operating system, if possible and the tcpip version as well. I think that is not the answer you want to hear, but the SSH implementation of OpenVMS becomes better with newer versions.

Re: SSH2 Transfer from Windows-Server to VMS-Server

The Version of TCPIP:

HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 4
on a AlphaServer DS15 running OpenVMS V7.3-1

I don't know if this version is the actual TCPIP-Version, but i have not the possibility to upgrade the Version (perhaps I can implement patches)

Re: SSH2 Transfer from Windows-Server to VMS-Server

I don't know if VMS V7.3-2 is critical in
this, but around here:

alp $ tcpip show version

HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 6
on a COMPAQ Professional Workstation XP1000 running OpenVMS V7.3-2

alp $ ssh "-V"
alp$dka0:[sys0.syscommon.][sysexe]tcpip$ssh_ssh2.exe: SSH Secure Shell OpenVMS (
V5.5) 3.2.0 on COMPAQ Professional Workstation - VMS V7.3-2

which looks much newer than yours.

Re: SSH2 Transfer from Windows-Server to VMS-Server

Hi Steusel

I agree with Steven. You should at least upgrade TCPIP.

We are using
HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 5
on a hp AlphaServer GS1280 7/1150 running OpenVMS V7.3-2

and we experience much less problems than with older SSH versions.

Re: SSH2 Transfer from Windows-Server to VMS-Server

The latest TCPIP V5.4 ECO does include a much improved ssh. I don't know if you can install it on V7.3-1

ftp://ftp.itrc.hp.com/openvms_patches/alpha/V7.3-2/DEC-AXPVMS-TCPIP_ECO-V0504-156-4.txt
ftp://ftp.itrc.hp.com/openvms_patches/alpha/V7.3-2/DEC-AXPVMS-TCPIP_ECO-V0504-156-4.PCSI-DCX_AXPEXE

Upgrading to VMS 7.3-2 is recommended.

Re: SSH2 Transfer from Windows-Server to VMS-Server

Thank you for your proposal.

The Upgrading is not so simple in a big company. I have to speak with my system- group.

But if you have other proposal, then let me know it

Re: SSH2 Transfer from Windows-Server to VMS-Server

I have found in my company a vms_server with 7.3-2.

HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 5
on a AlphaServer 1200 5/533 4MB running OpenVMS V7.3-2

The same effect as under Version 7.3-1

if you try to transfer bigger files, the transmission will be canceled. See attachment
