Well, I tried it and it works. It's almost certainly wrong so there's not much
chance of that patch getting into the kernel but I've had an ico running from a
fairly fast Alpha down a 100Meg ethernet for some time now and it's fine.

More investigation will follow when I get back. In the meantime the workaround
patch is:

I think I know what's happening but I'm not sure how to stop it.  The X server
has a SIGALRM timer that goes off every so often. If it's reading from the
DECnet socket when that happens DECnet, returns -ERESTARTSYS which the Xserver
interprets as an error and closes the socket.

I've tried changing this to -EINTR and it doesn't seem to make much of a
difference. Oddly, if I strace the Xserver running ico from a Unix box it never
seems to return -EINTR, only data and -EAGAIN. If you're feeling brave you might
like to change the ERESTARTSYS to an EAGAIN and see what happens ;-)

I can reproduce this easily. It just happens. DECterms and ico seem to be
affected so I can well believe that any X application will suffer. I haven't
used DECnet as an X transport for a while but I think it used to work - or, at
least, used to work better - if it hadn't I doubt I would have built all those
Xservers :-) 

Unfortunately both Steve and I will be away next week (though not togther!) so I
doubt much is going to happen on this for a while. I might get chance to have a
quick look at it this weekend but no promises.

OK, here's the offer. If anyone using DECnet on a distribution can tell me what
it was they needed to do to get it working and in which config files, I'll
consolidate them all into a single HOWTO.

Debian I can manage cos I wrote all that stuff anyway (plus, it's trivial!) - I
have some idea of RedHat 7 and SuSE 7 (though only the SuSE box is a real
machine rather than a VMware session) but any extra tidbits people have will be
appreciated.

Send them to me or the list and I'll make a start when I get back from summer
school early August.

Personally I'd rather spend the time coding but this seems to be something that
is really needed so I'm happy to help. If I get no responses then there will be
no HOWTO - this a community project :-)

On VMS you set the display as follows:

$ set display/create/node=<linuxnode>

and then run the commands as normal. I normally at this point do

$ create/terminal/detached

to get a DECterm up and running.

On Linux you will need to enable remote connections. being lazy (and on a
firewalled home network) I usually do

$ xhost +

which disables all security. You may want to be a little more specific and
enable specific nodes as in:

$ xhost +dnet:vmsbox

One tip. Linux doesn't have the same set of fonts that some of the standard VMS
utilities expect (eg 132 column text in a DECterm). If you have Alpha VMS box
you can copy the fonts from there to Linux and add them to the font path using
xset. I've never got the VAX ones to work though.

When Branden releases XFree86 4.2.0 for Debian I may get around to building a
DECnet-enabled Xserver for download. It would be really nice if the Xserver was
modular enough for protocols to be plugged in too - wonder if they've though of
that....

I think that you find ansvers to the VMS-related part of that question in the
comp.sys.vms FAQ.

I haven't actually tried to display anything on a remote decnet X server from vms,
but I have tried it on tcp/ip, and that is explained in the FAQ.

Re: [Linux-decnet-user] Duffer's guide

[<VH...@st...>]

I have several machines running Decnet on Conectiva, which is similar to
RedHat, and it will not work if started in rc.local. I have found that
Decnet must be started before the TCP/IP network is started. I put in
/etc/rc.d/rc5.d two symbolic links:

S10decnet -> ../init.d/decnet
S20network-> ../init.d/network

Otherwise, I guess one should do an ifconfig down before starting Decnet.
This is because I'm using the same interface for both Decnet and TCP/IP. If
you have a separate network interface for Decnet, you can start both
networks in any order.

Also, I put the following three lines in /etc/rc.d/decnet, at the end of
the start command:

     echo "pc576" > /proc/sys/net/decnet/node_name
     echo "1.576" > /proc/sys/net/decnet/node_address
     echo "eth0" > /proc/sys/net/decnet/default_device

Substitute node name, address, and device with your own values.

To check if it has started OK, type:

cat  /proc/sys/net/decnet/node_name
cat /proc/sys/net/decnet/node_address
cat /proc/sys/net/decnet/default_device

If no response is printed at any one of those commands, then Decnet has not started.

You are right I think. It should and its something that I'd like to
fix. It was on the road map for 2.5, but it will really depend on
the amount of time I can reasonably spend on the code at the moment.

I would very much like to update the docs too, but time is again the
limiting factor. Some time ago Patrick and I wrote an article for
Linux Journal and I think that its certainly time to have another go
at something like that since the original is out of date.

I'm on holiday next week, so nothing much will be happening during
that time, but once I'm back I'll think about the best way forward
with this. Suggestions are welcome as always,

Steve.

This is probably one for Steve Whitehouse, but why doesn't the DECnet
driver default to taking the DECnet address from the MAC address? If this
hasn't been set correctly, surely DECnet isn't going to work anyway.

You weren't wrong - the first time I typed it I messed up

Everything seems good from the command line - I just have to learn how to
use them now

I will probably pause now to write up my RH7.3 procedure - incase I forget
later (and this box is a trial for moving people in the company of windows
and onto linux - so hopefully I will need it later)

A quick X question though....

OK - so I install a new XF86 file to /usr/X11R6/bin (from your pre-compiled
downloads) to update it to decnet capable.

How do I start a remote X-session??

I havn't done it yet but I plan to and it is fairly fundimental to the
workstation changeover

Hey - I said I was a newbie/duffer

P.S. Is any kindly person planning to build a XFree86.gz for XFree86 4.2.0?

Part of the problem with a duffers guide is that is is very distribution
dependant. So the installation on RedHat varies considerably from Debian
(where
DECnet is part of the distribution).

You're right - a newbies HOWTO is very much needed, and I suppose a Red Hat
one
would probably be the most commonly useful.

You probably need to "echo 5.400 > /proc/sys/net/decnet/node_address"

after that you should start to see the otehr DECnet nodes appearing in
/proc/net/decnet_neigh.

Can I second this request? I'm reasonably knowledgeable about VMS, DECnet
and Linux, but I go for months (sometimes years) without using DECNet under
Linux, then when I need to use it I've forgotton how everything works...
Also, the kernel code and dnprogs have changed quite a bit over the last
couple of years and it would be useful to know what works with what.

Personally I don't see the distro dependent stuff as all that important -
after all, RH people don't *have* to start daemons in the RH manner (for
example), they can just stick a line in rc.local or whatever. It's more a
question of setting the MAC address, setting up the config files, kernel
dependent issues etc. Most of this info is around *somewhere* but it's
often not obvious where. A short(ish) cribsheet would be really useful, or
even a list of documentation links with a description of what each covers.

You could send it to everybody on the list every 6 months...

I have added the MACADDR to etc/sysconfig/network-scripts/ifcfg-eth0

I have rebooted, started-stopped-restarted networking and tried as many
things as my newbie brain could come up with, I have looked at the website
(particularly the FAQ) and that is predominantly helenic to me

So - the question is....

What blindingly obvious steps have I missed?

Thanks in advance

Nick

Re: [Linux-decnet-user] MAC Address Calculations

[Rob D. <rob...@wo...>]

A math version of the calculation that you can do in the Windows
calculator is:

- Take the last two hex numbers
- Swap the order, and join them together
- Convert to Decimal
- Divide by 1024
= The whole number is the area number
- Subtract the area number from the value (you should be left with a
fraction)
- Multiply by 1024
= This number is your node number

It's because the last two hex digits are actually a 16bit number with the
address taking up 10 bits and the area the remaining six. so 1.10 is actually:

000000 00 00000000
000001 00 00001010
        4        A

so. 5.400 would be

000101 01 10010000 
       15       90
       
thence:

AA:00:04:00:90:15 (cos it's in little-endian format)

There's a script in app/setether.sh that will do this for you (it's what I used
for the Debian startups).

[Linux-decnet-user] MAC Address Calculations

[Nick H. <nic...@ip...>]

Hi all,

*Newbie Alert*

I am having trouble working out the MACADDR for a given Node

From http://linux-decnet.sourceforge.net/faq-single.html I got that
MACADDR=AA:00:04:00:0A:04 = 1.10

And from http://linux-decnet.sourceforge.net/kernel.html I got The form of a
DECnet physical address is AA:00:04:00:XX:XX The last two hex digits codify
the DECnet node address. 

So MACADDR=AA:00:04:00:0A:04 

0A = 10 - That I can get simple Hex-Dec convert

However

04 = 1 - That I can't work out

Can anyone help me get my brain arround it (and if someone wants to work out
5.400 I'd be most greatful *Grin*)

Cheers

Nick

[Linux-decnet-user] Help decnet/XFree Problem

[BASSIR M. <Moh...@ax...>]

Hi,

I have install dnprogs-2.17-1 on my distrib Mandrake 8.1
with XFree86-4.1 for decnet.
On end of /etc/rc.d/init.d/decnet script i have added
	echo "eth0" > proc/sys/net/decnet/node/default_device
	echo "3.201" > proc/sys/net/decnet/node/address

On /etc/sysconfig/network-scripts/ifcfg-eth0 script i have added
	MACADDR=3DAA:00:.......

/etc/decnet.conf properly configured

1)
Now, we succeed to log from my Linux PC to the Alpha Open VMS server 6.1 =
with sethost utility. We also succeed to open a decterm over decnet on =
PC linux.
But when i am running ico program on Alpha server and dislayed on PC =
linux it crashes after a while (randomly between 1 to 5 seconds) with =
messages:
XIO: fatal IO error 65535 on X server "_WSA15"
	after 19253 request (7 known processed) with 0 events remaining.
%LIB-F-IOERROR, xlib io error
......network partner disconnected logical link.

2)
When i tryed to use the dndir command, some time to time it works well =
and sometime it gives messages "write: ...unrecognized object"

3)
When i tryed to use the dnping command, some time to time it works well =
and sometime it gives messages "Reading from VMS: transport end point is =
not connected".

Do you have any idea to solve these problems?

Thanks.

[Linux-decnet-user] dnprogs 2.19 released

[Patrick C. <pa...@ty...>]

I've sat on this release for far too long.

  * Makefile fixes
  * startnet fixes to arg parsing
  * phone uses pixmap directory properly
  * ctermd now responds to DEL, ^X etc (hooray!)
  * dnetd task_server now won't run arbitrary programs.
  * dntask prints error messages if the connection fails.
  * setether uses "ip" command if available rather than ifconfig
  * Added timeout switch to dnping
  * FAL no longer eats directories starting with '0'
    Thanks to Matjaz Godec
  * Add virtual-root feature to FAL
  * Change to libdnet_daemon to allow RSX to connect
  * Fixed truncate option in FAL
  * Fixed wildard fetching in FAL so it works with dncopy
  * Changes to FAL to allow RSX file transfers
  * Fix sending of binary files by FAL by block.
  * Add .html, .tgz & .bz2 file types to FAL types list

The RSX work in FAL is only partially complete but I'd appreciate any testing
and feeback people can offer if they want this feature to work well.

Re: [Linux-decnet-user] OT: OpenVMS limit on disk size?

[Eduardo S. <ems...@ho...>]

Hi,

OpenVMS 5.5-2 hardly support generic scsi disks. For examples connecting a 
Seagate SCSI disk of 1GB to a uVAX running OpenvVMS 5.5-2
gave a "FATAL DRIVE ERROR". Many other brands would fail the same way.
At that time, Digital Introduced patches for the DKDRIVER.EXE (SCSI disk 
driver) and some of this 3rd party disk could be used.
From OpenVMS 6.2, Generic SCSI disk support got better, but there's still 
some issues connecting UWSCSI  disks to a Fast SCSI controller.

You didn't mention which brand/model  and capacity are you purchasing.
Are they from Digital?

Regards,
Eduardo

[Linux-decnet-user] OT: OpenVMS limit on disk size?

[Tom R. <ry...@ma...>]

Hi folks,

Sorry for the off topic post, but this is as close to a VMS list as I 
get....

Anyway, does anyone know if OpenVMS 5.5-2 has a limit on disk sizes? I 
am purchasing some external storage for our MV3100/95 and want to make 
sure that it will work....

Many thanks,

Tom
