networking P.C to OpenVMS cluster for file transfer

[nipun_2]

Hi,
We have usually 500 MB + size of files (mainly image files) to transfer to P.C to perform various analysis. Currently we have setup the system (openvms V 7.3-1 3 node cluster with one server node and 2 satellite node) for ftp access.

So we have
Server connected to satellite node 1 (XP1000( and satellite node 2 (EV 68) via Gigabit Ethernet switch. They are communicating over DECNET and systems are running Decnet Plus. We have common system disk housed in Server node.

Due to
- Low internet speed
we are thinking of connecting P.C directly to the internal GIgabit switch so that we can have file transfer of 1 gb. Is that possible

if so how?

You don't say , what system is running on the PC:
Linux/Unix: install/start TCPIP on the VMS server, export the disk(s) via NFS to the PC, NFS-mount the disk on the PC; then us simple mv or cp command on the PC.

If You have some kind of MS Windows on the PC, You could provide Windows file-sharing from the VMS side: either use TCPIP and install the SAMBA for VMS (on the Freeware CD), or
install the commercial "Advanced server for VMS", which implements Windows file sharing.

The simplest (but not so handy) is to have TCPIP on both sides, and use FTP to transfer the files.

Hi Josebh,
Thanks for the reply.
I have windows XP. You mentioned installing Samba client or other option is using TCP/IP

So I have to configure the network to also work on TCP/IP as well as DEcnet?

We have the Server configured for TCP/IP (static address) however the Server has 2 ethernet cards
Gigabit card used for internal network running over Decnet while
Fast Ethernet card is connected to the Internet Line.

So what would be easier (I am new to OPenVMS) using TCP/IP or using the Samba from freeware CD

[Ian Miller.]

Do you have TCP/IP configured on the Gigabit interface on the VMS systems?
If not then either
a) configure it and use the various suggestions so far (NFS/FTP/Samba/advanced server)
b) install DECnet on the pc (from Pahtworks CD shipped with VMS - requires licence)

[nipun_2]

Okay I will follow up on that and update this thread in about 2-3 days

I know it is configured for the Fast Ethernet port. I do not know about the Gigabit port

I am assuming doing show network "tcp/ip" /full
will show me the ethernet device name.

If I do not find the device name for the gigabit card then I probably have to configure it or I can intall Samba and somehow use that?

Let me know if I am going in the right direction.

Thanks in advance

[Ian Miller. · Accepted solution]

samba will need tcp/ip configured.

$ TCPIP SHOW INTERFACE

Will show the configured interfaces.

Nipun,

For the past few years OpenVMS has been packaged with one or two Advanced Server licenses. You might check to see if you have PWLMXXXCA07.03 or something similar on any of your nodes, or in with your paper PAKs.

nipun,
all connections (NFS,SAMBA,FTP) need TCPIP, only advanced server works with Decnet (and the pathworks software on the Windows side).
You write the VMS systems are connected to the Gigabit switch, then @sys$manager:tcpip$config should offer the corresponding interface for configuration.

[Joseph Huber_1]

Nipun, I overlooked the "server has 2 interfaces":
You can still stay connected with the first interface to the internet (or the extended LAN), and use the second one (gigabit) for a local IP network, using one of the "local" IP network-address-domains 10.x.y.z, 172.16.0.0-172.31.255.255, or 192.168.y.z .


Give all nodes on this network local names
(using set host name/addr= in TCPIP), then they are all reachable by name.
Those nodes with only the gigabit connection are not able to reach the internet (unless You have a NAT router, but this beyond the actual discussion).

Alternatively:
Assign normal internet addresses (assigned by Your network manager ?), and define the server (the one with 2 network connections) to be the default gateway for the others.
This way all nodes can make use of the gigabit speed, and still are reachable on the internet.

thanks for the info guys.
