"protocol error, server_vms closed connection"

rbpkirow — Mon, 07 Nov 2016 08:56:02 GMT

Hello.

I have an error when I want to run a comand on a VMS client from a linux server: "protocol error, server_vms closed connection"

I have made the following steps:

My linux user is root, and my vms user is rbpkirow

on VMS client: I have added the proxy for the user I want, and added the ucx for the server

TCPIP ADD PROXY rbpkirow/HOST=LINUX_SERVER/REMOTE_USER=root

ucx set host LINUX_SERVER /add=192.168.1.2

On Linux server:

Added hosts file the vms IP address

Now I run:

rsh -l rbpkirow vms_client "dir"

but I receive the error 'protocol error'

Can anyone help me?

thanks in advance

Probably not, if you won't answer some basic questions. As someone
was asked when he reawakened that thread from 1996 in comp.os.vms:

Which Linux version, and which version of OpenVMS and TCP/IP
Services?

      Is this system using a hardware emulator and an emulated network
      involved, or is OpenVMS booted directly on VAX, Alpha or Integrity
      Itanium hardware?

What sort of network connection is in use? [...]

And so on.

Wouldn't that be a VMS server and a Linux client?

Does "rsh" work from the VMS system to itself? From the Linux system
to itself? From other systems to the VMS system? From the Linux System
to other systems? Do any other network services (Telnet, FTP, ...) work
between these two systems?

For the record, around here:

sms@deb74:~$ cat /etc/debian_version
7.10

sms@deb74:~$ uname -a
Linux deb74 3.2.0-4-amd64 #1 SMP Debian 3.2.78-1 x86_64 GNU/Linux

sms@deb74:~$ rsh alp-l show default
ALP$DKC0:[SMS]

And, at an operator console:

ALP $ tcpip show version

HP TCP/IP Services for OpenVMS Alpha Version V5.7 - ECO 5

Of course, my SYS$SYLOGIN and SYS$LOGIN:LOGIN.COM both work without
errors.
