Heh... this is obviously the way we did it in UNIX decades ago... I always complained about trying to use UNIX for the very thing it seemingly opposed (strict user controls) ...
... and we still do this; I can't keep users out of the OS an in the app... argh...
Surely VMS can do better!

Just a suggestion. Why not have TWO directories?
(a) WRITE ONLY - anyone can send files to it - normally named: INCOMING
(b) READ ONLY - anyone can read any file
Just in case, you can (probably should) monitor
what is added to (a), then copy it over to (b)
ONLY after it is checked. Having (a) which
only you can look at (you might allow the contents
to be displayed, but I would not recommend it)
provides much better security. I also suggest that
for any file larger that 10 MB, an MD5 checksum
also be sent so you can verify the large file was
sent correctly.

You can try SLAVE which is connected via a dial up. Not tried it in a while but it should still work OK.

In an NI cluster you can get away with expectedvotes=votes. IMHO disk corruption can only happen if another host accesses a local disk outside the DLM. In a CI or DSSI cluster this can happen and lead to multiply allocated blocks errors.
An alpha takes more time waiting to form a cluster, even with expectedvotes set to votes than a VAX. I haven't tried it on an rx2600 as yet.
In production I once configured a two node VAX 3100 NI cluster. Expectedvotes set to 2 and votes to 1. Each node had a local disk designated as quorum disk, one vote. All other disks were shadows et between the two systems. This thoroughly unsupported configuration ran for years until DEC forced a micro VAX 2000 on us. The supported cluster had more user down time once one of the host went down. In the unsupported cluster the vote of a quorum disk came into play only if the other VAX failed and almost noticeable, no cluster reconfiguration that took many seconds.

OK. First, 2 node clusters can be problematic due to not realy having the
necessary number of node to properly form a cluster. The minimum is three
nodes to form a cluster.
However, let's look at what you said.
You said that the VAX boots and forms a cluster. It has one vote and the
expected votes is one. Therefore, when you boot it, it sees the necessary
number of votes to continue booting and form a cluster.
You also said that Alpha boots and hangs trying to form a cluster. It too
has one vote but its expected votes is two. Therefore, until the VAX has
booted, the number of votes is not present and the Alpha will hang.
If you lower expected votes, the Alpha wil boot just like the VAX does. I
would caution you read the VMS documentation regarding clusters and how to
determine quorum. You risk, in the configuration of two nodes where each
has one vote and expected votes of one, partitioning the cluster resulting
in data corruption.

Thanks for the reminder of these issues. To be honest my experience with clustering is limited and generally specific to satellite based configurations. In this case I may make the VAX a satellite of the Alpha with the local disk acting as page/swap.
Am I right in thinking then that the relationship changes somewhat in that the Alpha will always need to be up but the VAX can come and go as it pleases (with the correct shutdown sequence)?

AFAIR Johnny's bridge is capable of forwarding LAT so I can see a load of services on the DECSERVER if I type SHOW SERVICE.

Do ACLs like that carry over DECnet? I seem to recall Brian S. saying they don't.
You are correct, sort of. However, you wouldn't apply the ACL to the file. Rather, specify a default protection ACL on the directory to contain the files. This would configure the security attributes of any file placed in it, which to my thinking should work.
I use something similar so that when I copy stuff into my FTP directories they are immediately set up to be served via either HTTP for FTP. Here is an example of the way to set it up (assuming DROPBOX is CONCEALED logical):
$ CREATE/DIRECTORY DROPBOX:[DROPBOX]
$ SET SECURITY DROPBOX:[000000]DROPBOX.DIR/OWNER=... -

Yeah, that's the way to go. I'm tempted to buy an ancient Nokia GSM phone, get a data number for it and a serial adapter, and plug it into my DS300..9600 bps dial up access, woo hoo!
Hmm, looks like the Nokia 9210 can combine several GSM channels for thruput up to 38400 bps with the right configuration and it's effectively an ISDN connection (V.110). I think I need to acquire one of these, data line subscriptions are cheap in Finland and the phone costs about 50 GBP...

Sampsa where are you based at the moment? Looking at what you posted,
I guess I'm a bit surprised.
