If you were running samba on the Alpha then that implies you
have TCP/IP on it too ?

If that's the case you could NFS mount the VMS disks from 
Linux and serve them out via samba on Linux.

A bit indirect but it should work!

Hi,

You can copy files on to the Linux box with the tools and then serve them
from samba (maybe you want to set the copy up as a cron job) but you
can't directly mount a remote filesystem over DECnet at the moment.

Eventually we hope to have that feature but it will depend upon the
time we can spend on writing the code as its all done in spare time
and odd moments of which I've not had very many lately unfortunately,

Re: [Linux-decnet-user] Sorry, how do I configure node_address

[J M <joh...@ya...>]

If I have decnet, does this mean I can get a file from
the "real" dec machine and serve it to a client
through samba?

The whole reason for getting decnet was because samba
2.2.7 never worked properly on the alphas.

I thought if I had decnet, then I could get to the
files on the dec machine and use the samba on linux to
serve those files to an SMB (winnt) machine.

Will it work for that?

Re: [Linux-decnet-user] Sorry, how do I configure node_address

[Steven W. <st...@gw...>]

Hi,

If you've got DECnet in your kernel you should have /proc/net/decnet_dev.
If you are having problems with the device being busy its because you
can only change the MAC address when the device is down, so if you
run ifconfig eth0 it should not show "UP" in the list of flags on the
third line of output when you start to run startnet,

Steve.

I have do not have a decnet_dev file under /proc.
But, thanks.

Running startnet -hw eth0, just gives:

Re: [Linux-decnet-user] Sorry, how do I configure node_address

[Steven W. <st...@gw...>]

Hi,

Yes, it is. See the linux/Documentation/networking/decnet.txt file for
more info on how to set it. If you have problems setting the default
device then its most likely because you are trying to use a device which
has not been configured for DECnet. You can check which devices are valid
by checking the /proc/decnet_dev file to see if its listed in there, if it
isn't you can't set it as a default device, so you need to ensure that
you configure your interfaces before you try setting the default device,

Thank you for your response.

Here is the directory:

-rw-r--r--    1 root     root            0 Mar 24
17:22 debug
-rw-r--r--    1 root     root            0 Mar 24
17:22 default_device
-rw-r--r--    1 root     root            0 Mar 24
17:22 di_count
-rw-r--r--    1 root     root            0 Mar 24
17:22 dn_count
-rw-r--r--    1 root     root            0 Mar 24
17:22 dr_count
-rw-r--r--    1 root     root            0 Mar 24
17:22 dst_gc_interval
-rw-r--r--    1 root     root            0 Mar 24
17:22 node_address
-rw-r--r--    1 root     root            0 Mar 24
17:22 node_name
-rw-r--r--    1 root     root            0 Mar 24
17:22 time_wait

All of them have rw for root, and I am the root user. 
For whatever reason, the simple echo -n >
default_device will not populate.  I cannot change it.
 Everything else I can - just not default_device.  I
have no idea why.

We are obviously missing some part of your problem.  Are you trying to
change the default device as root or as an ordinary user?  Observe:

$ ls -l /proc/sys/net/decnet/
total 0
dr-xr-xr-x    7 root     root            0 Mar 24 17:33 conf

-rw-r--r--    1 root     root            0 Mar 24 17:33 time_wait
$ echo -n "eth0" > /proc/sys/net/decnet/default_device 
bash: /proc/sys/net/decnet/default_device: Permission denied
$ su -
# echo -n "eth0" > /proc/sys/net/decnet/default_device
# cat /proc/sys/net/decnet/default_device
eth0

Or perhaps the problem is that you're attempting to edit with a text
editor?  You can't do that with /proc because it isn't populated with
static files -- all of the content is dynamically generated by procfs. 
However, cat and echo will work for reading/writing in /proc, provided
your owner/permissions line up with the resource you're trying to read
or modify.

Maybe your Network is up, before decnet starts.

Try this:

/sbin/ifconfig eth0 down
/etc/rc.d/init.d/decnet start

[Linux-decnet-user] eth0 device busy

[J M <joh...@ya...>]

I get this error when trying /etc/rc.d/init.d/decnet
start:

Starting DECnet: Error setting hw address on eth0:
Device or resource busy


doing this reveals there is no entry, so I don't know
if it matters:

cat /proc/sys/net/decnet/default_device
(gives nothing)

doing echo -n "eth0" >
/proc/sys/net/decnet/default_device

does not update the file.  Doint the echo -n to
node_name, node_address, does work.  It just wont
change the default_device file, but as I said above, I
don't know if it matters, because when running the
startup script, it mentions eth0 anyway.  It just says
it is busy.  Thanks for any guidance.

Thanks for the help, but I cannot edit the file.  This
is why the echo -n won't work.  This is the whole
reason for writing to the group, because the online
docs say to use echo, but one cannot edit /proc files,
so it makes no sense and there is no sysctl variable
to change.

HTH,

[Linux-decnet-user] How do I modify default_device?

[J M <joh...@ya...>]

I have RH 7.2.  I used make xconfig to enable DECNet support.  After compiling, etc. and rebooting.  I can go to:

/proc/sys/net/decnet

And there are many files there.  I have read how to change the appropriate ones.  But I cannot edit them at all because they are in /proc.  I have to use sysctl to modify the settings.  But, I cannot alter default_device as it is not in sysctl and I cannot modify it directly.

I believe this is why I get "no route to host," but I cannot change the value!  Thanks for any help.

Thanks for that report, there's a limit to the number of distributions I can

The new build system in latd 1.17 is something I am particularly keen for
feedback on as this is the first time I have used GNU autconf for a prject.

This doesn't really surprise me. If you have any fixes or just suggestions as to
what is going wrong then I would like to have them. My dev machines run Debian
and I have a VMware instance of Red Hat but more than that gets a little
unweildy (as well as time-comsuming).

Could be awkward. I never managed to get that sort of loopback to work with ts10
or simh. I suppose it /might/ work if you dedicate an ethernet card to the
emulator (so the other card would see the traffic). There are possibilities of
doing it with simulated devices like tun/tap I think. but I haven't tried that.

[Linux-decnet-user] Linux-decnet and Slackware

[Gregg C L. <dr...@wo...>]

Hello again from Gregg C Levine
As most of you will note, it has been a while since I have posted to this
list.

I thought I should mention somethings.
1) Both latd-1.17 (Which was the latest version that I found on
ftp://ftp3.sourceforge.net:/pub/sourceforge/linux-decnet ), and dnprogs-2.22
(Same as above.), compile without complaints on Slackware 8.0.

2) As for installation, the make file for dnprogs-2.22 does not correctly
figure out how to install the scripts for setting up the environment.

My other questions deal with the notion of connecting Linux-decnet to a
running instance of E-11 on the same machine. But I shall reserve them for a
later time.

[Linux-decnet-user] latd 1.17 released

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

This is a major release in some sense, though a lot of you may not notice.

The big change is that latd now runs on NetBSD and Darwin as well as Linux, and
a consequence of this is that it now uses GNU autoconf to build, so if you want
to compile from sources you will need to

./configure && make

rather than just "make" as before. This is unlikely to happen to the DECnet
progs BTW as they are not going to be portable any time soon.

A huge thanks to Matthew Fredette of NetBSD for doing the NetBSD port and much
of the autoconf work. I have put further work into integrate his changes (which
were made to quite an old version of latd) and also used his work to port to
Darwin so it now runs on my laptop :-)

Currently, it will compile but not run on FreeBSD because of an error setting up
the multicast address, if anyone knows how to fix this then please let me know.

The changelog is below, there are some bugs fixed too, so even if you don't care
about non-Linux platforms it's probably still worth upgrading.

  * Add support for a MOPRC_INTERFACE env variable.
  * Fix bug in the lastest retransmit code that screwed up
    queued connections rather badly.
  * Don't show status messages to /dev/lat ports
  * moprc is now a C++ program that uses the LATinterfaces class.
  * llogin -p only locks devices if liblockdev is found
  * Porting work for *BSD and Darwin.
    HUGE thanks to Matthew Fredette of NetBSD for all the bpf work.
  * Use autoconf to configure and build. Again Matthew Fredette did
    most of the work for this, but I added the Linux bits.

If you have any comments on the new build system (like it fails for you!) please
let me know.

[Linux-decnet-user] ods2 FS for Linux

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

From the freevms list:

There is an ods2 filesystem kernel module for linux (readonly) available:

ftp.nvg.ntnu.no:/pub/linux/ods2

You'll need to tweak the Makefile to make it compile but it does work.

I have a patch to make it work on Alpha. If anyone wants it then I'll make it
available. I posted it to the freevms list but got no reply.

[Linux-decnet-user] DECnet kernel update

[Steven W. <st...@gw...>]

Hi,

Its a little while since I last updated everyone on what I'm working on for
Linux DECnet at the moment. I've got a new work-in-progress patch which is
available here: 

http://www.chygwyn.com/~steve/kpatch/decnet/decnet-2.5.64-routing2.diff

Its feature enhancements for 2.5 mostly - preparing the way for us to add
zero-copy (needs a tidy around sendmsg/recvmsg first, which is done in this
patch) and also starts to tidy up the routing code. This is an area which
has been neglected for too long and I'd really like to get it fixed up.

Part of the plan is to make it as similar to the IPv4 routing code as possible
in order to take advantage of the work in optimising the code which has already
gone on in the IPv4 stack and also so that people working on the IPv4 code
will feel at home looking at the DECnet routing code to encourage them to
help us along. This work-in-progress patch adds support for DECnet into
flow.h and uses the struct flowi as a routing key, some further adjustments
need to be done before the patch is submitted, in particular dealing with
the "scope" of routes.

In the future, as well as adding zero-copy support, the other major work
item on my agenda is to change the way that the routing code works so that
the current default behaviour will be maintained by the automatic addition
of route entries into the routing tables. At this stage all routing decisions
will be made by lookups in the routing table, unlike the current situation
where many of the default rules described in the DECnet documents are
implemented as special case rules built into the code and the routing tables
are an extra add-on.

This seems to make more sense to me since it will clean up the code and also
mean that in special cases where people don't wish to (for whatever reason)
abide by the default rules, they'll find the system more flexible.

Please feel free to send me any comments, questions or suggestions,

Steve.

P.S. An article on the Linux DECnet project written by myself and Patrick
Caulfield is in issue 27 of "Linux User" but only the news stand version I 
gather. A similar article will be appearing in "Ping" in the near future.

This is rather odd - I've never heard a report of that before.

>  Trying to remove the DECnet module with RMMOD says "decnet: device or resource busy".
Yes, thats because you can't unload the DECnet module as the support to shut
everything down cleanly isn't there. It might eventually appear in 2.5 or
above as since that decision was taken certain bits of the core kernel code
have changed to allow removal cleanly.

Should do. I don't know any network cards which you can't set the mac address
on. Try an ifconfig and see if its worked or not.

Yes. It sounds like you may not have set the default device ? You need to
set it to the external interface (eth0 usually). Also look in /proc/net/decnet*
and /proc/sys/net/decnet/* to see if the settings are as you expect,

Steve.
