Force TCP NFS Mount with TCP/IP 5.6

[Vuffray Joris]

Hi,
I'm trying to force an openvms system to mount an NFS share over TCP instead of udp.
Is there a special mount command to do that?

[Wim Van den Wyngaert]

ucx set servi nfs/port=xxx/prot=tcp ?

Don't have a system to test it.

Doesn't work.

Check tcp_threads params.

I'll check that.

Thanks for the link...

For the client part it's not that clear. Unix clients can use mount /protocol (or equiv) but VMS seems to have no option.

The info on service level is simply not used. It's simply a db that a service may read to get params but it's not obliged to do so.

I've just tried to skip upd on the NFS Server side (RHEL4), but the VMS Client is then unable to connect & mount the FileSystem.
got:
-SYSTEM-F-NOSUCHOBJ, network object is unknown at remote node

Strange...

I'm wondering if TCP is really supported by the client.

[Wim Van den Wyngaert]

Oeps. Didn't notice that you only need the client. Whatever. I learned already something.

Could it be that portmapper is used to find the protocol ? Ot says something in the log file about MOUNT and protocol.

Tried it on TCP 5.3. VMS to VMS. Not working either. Can't force the client into TCP.

I did succeed in getting a hang of the NFS server. Stop/id and disable servi didn't work. After a reboot my client still didn't work. Had to reboot the client too. Nice ...

TCP for the NFS Client is a new feature of the 5.6 Version; so it won't work with 5.3

[Wim Van den Wyngaert]

The server is clearly supported in 5.3 eco 2.

How do you specify the client tcp mode ?

Wim

[Vuffray Joris]

Is the server side supporting TCP in 5.3a?
I'm speaking about the client side. They mention TCP support 'til version 5.6

How to specify TCP in client mode is the reason why I opened this post: I don't know.
I couldn't find any Infos in the docs...

[Wim Van den Wyngaert]

Yes it's in 5.3. ucx sho dev (I know, it's not ucx) shows 2 listeners : 1 in DATAGRAM and 1 in STREAM. So, it's supported. IOn server level.
