LANCP DLL fails to downline load DECserver boot file

[Kortlandt]

Hi,

I've got following problem:

I enabled a device for all DLL requests, but DECserver can't download boot file.

$ MC LANCP SHOW DLL:
...
LLB0 enabled in selective mode for all requests, data size 246 bytes

No messages appear in OPCOM (REPLY/ENA=NETWORK),
Number of loads does not change (MC LANCP SHOW DLL)

In order to get it working, I have to define the decserver with address to allow the DECserver to boot.
MC LANCP DEFINE NODE DS0001 /ADDRESS=08-00-2b-12-34-56 /BOOT=OTHER
MC LANCP SET NODE DS0001 /PERM

This is in contradiction with "for all requests" on the LLB0 device.


MC LANCP SHOW NODE
Node Listing, volatile database (9-FEB-2009 14:29:56.69):
(Catchall entry):
DS001 (08-00-2B-12-34-56):


I'm running OpenVMS 7.3-2, Sysupd 16.


Anyone any clue?

Thnx,
Bob Kortlandt

I use mop via ncl so no experience with lancp.

But study the "help def node/file" in lancp. You need to specify the file to load (in my case sys$sysroot:[decserver]wweng2.sys.

Hi Wim,

Problem is that ALL DECservers should be able to upload, they'll ask themselves for the file they need.

I don't want to specify every DECserver's MAC address.

Grtz,
Bob.

Bob,

Check that DECnet isn't "stealing" the request.

Have you MOP via DECnet enabled ?

Hakan

[Hakan Zanderau ( Anders]

Forget my answer......
You want to boot all your DECservers via LANCP instead of DECnet, right ?

Just a guess:
>>
No messages appear in OPCOM (REPLY/ENA=NETWORK),
Number of loads does not change (MC LANCP SHOW DLL)
>>

To me this indicates no request is coming in at all, otherwise You would see an error message from lanacp.

So there must be some lower level problem: decservers not in same (brigded-)LAN ?
MOP protocol not enabled in bridges ?
Filters in switches ?

[Wim Van den Wyngaert]

mc lancp show acp

indicates if OPCOM is given or not. You can also enable other useful stuff.

Wim

[Wim Van den Wyngaert]

mc lancp show dev/dll
will show if only known clients are accepted and if mop is enabled for the (network card) device.

Is the KNOWNCLIENTSONLY option set ?

LANCP> show dev llb0 /dll

[Wim Van den Wyngaert]

I hope you did install the decserver files on the correct place (the ww* files).

Wim

[Wim Van den Wyngaert]

When NOKNOWNCLIENTSONLY is selected, LANACP searches the LAN$DLL directory for any images requested by clients that are not defined in the LAN permanent node database.


I wonder if it would work if you remove the entry from the db. You created a KNOWN entry and that would not search the directory.

fwiw

Selective mode is a special mode where packets, as was stated, are stolen away from any other users, usually DECnet MOP. But only packets defined by addresses in the node database are 'stolen' like this and passed to LANACP.

So normally, you do have to define the node.

But the idea is that packets that would not otherwise be delivered to another user should also be processed by the 'catch all' definition. I am not sure, but I think there is a bug in the handling of 'selective mode' in the LAN common routines.

If you can, escalate the problem. This is on my list of things to address, and I'll get to it sometime. Meanwhile, define the node explicitly.

Thnx for all answers,

@Hakan: I just use LANCP, DECnet is not used for DLL.

@Joseph + @Wim: If I define (and set) a DECserver MAC address in the database, DECserver loads it's boot file, I get OPCOM messages, and I can see that the # of loads increases. Network is OK, I guess...

@Ian: Problem is that if I set NoKnownClientsOnly, I expect that undefined DECserver will load as well, but they don't. It seemes that it doesn't matter what I set, I still have to define the DECserver and MAC address.

@Dick: I'm afraid you're right.
For the record: OpenVMS 7.3-2, Sysupd 16, LANCP 5.0

I will try and setup a test on a Sysupd 13 system...

Grtz, Bob

[Kortlandt]

unfortunately, the system was already upgraded, can't perform test.

I will try and escalate this problem...

Thnx to all for help.

Bob.
