[Linux-decnet-user] VMS TCP/IP on emulator without ethernet

[<Wd...@ao...>]

About a year ago, I tried to get SLIP running, and I think I had to manually 
create the serial SLIP device with something like 

DEFINE COMMUNICATION_CONTROLLER SL /TYPE=SERIAL
SET CONFIG INTERFACE SL0

or maybe it was

SYSGEN> CONNECT xxA0 /NOADAPTER /DRIVER=zzDRIVER

then run the UCX$CONFIG or TCP$CONFIG (or whatever the command file name is). 
 I couldn't get SLIP to work, then found out that the serial port on the 
other computer was bad, and I never made the time to try again.  But, I was 
able to start the stack and ping myself and telnet to myself.

I suppose the other thing it would allow you to do would be to tunnel DECnet
over the internet - using SSH for security I suspectd that might make quite a
good wide-area DECnet network.

Incidentally I tried setting up SLIP in CHARON-VAX on Friday but the VMS TCP/IP
stack doesn't want to start without an ethernet card :(

    This brings up another point that I've wanted to talk about: using
the
MultiNet TCP/IP product for VMS, it's possible to encapsulate DECNet
inside of TCP/UDP/IP packets.  Therefore, it could be possible to have
a DECNet WAN/LAN using TCP/IP over SLIP or PPP without having to
have a network card on the PC.  But the cost of network cards have
plummeted so much lately.

    Anyway, just a thought...

It's probably possible to set up PPP from that emulator to Linux but I've never
tried it. You would, of course, need to install TCP/IP on the "VAX" .

[Linux-decnet-user] VAX emulator

[<Wd...@ao...>]

Patrick said "it is possible to set up DDCMP networking to a real VMS 
machine".

Is it possible to set up SLIP to anything else, and if so, can you SLIP with 
the emulated serial port directed to a telnet port?

[Linux-decnet-user] Free VAX emulator

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

The Free VAX emulator Charon-VAX is available for Linux again:

http://www.softresint.com/charon-vax/hobbyist.html

It doesn't include any ethernet support but it is possible to
set up DDCMP networking to a real VMS machine or to another 
Linux/DECnet box using Eduardo Serrat's ethddcmp package. See the
links page for the download and please read the instructions carefully.

Also new to the links page is Nicolas Dupeux's DIBOL->C translator.

[Linux-decnet-user] LATD 1.13

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

Not quite a brown-paper bag release but plenty of bugfixes for the new features
in 1.12 as well as things I broke earlier on in the 1.1x series - thanks to
those that reported problems.

The changelog looks like this:

  * Fail attempts to create /dev/lat ports twice
  * Delete /dev/lat ports when latcp -D -p is run
    (thanks to Denis Komissaro) for those two.
  * Use local name in ENQ message for DS90L servers instead of the
    stupid one I left in there after testing.
  * Get rid of spurious "Queued" status messages and put the
    service name in there.
  * Fix multiple queued connections to the same server that I broke in 1.11
  * Don't make queued connection queries interfere with existing services table
  * Restrict data slots to 250 bytes so as not to break DECserver 200s
  * Made the keepalive timer less susceptible to drift on busy systems.

[Linux-decnet-user] IRC

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

I've created a #decnet channel on irc.openprojects.net - if anyone fancies a
chat about DECnet on Linux or LAT then meet me there. 

I'll be on as "pjc" usually between 8 and 5 GMT weekdays and more randomly at
weekends.

[Linux-decnet-user] LAT 1.12

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

I've tagged and upload the latest LAT. There are a few new features in this
release that I hope people will find useful. Be aware that I still regard this
branch as the "unstable" one but I think it's probably more stable than the 1.0
series now - please let me know if you disagree.

New features since 1.11 are:

* llogin -r is an alias for llogin -R (easier to type!)
* New moprc program for remote administration of terminal servers
* llogin can now connect to passworded services using llogin -w
* Split out Linux-specific code into its own class
* Primitive, but functional support for DS90L terminal servers

New features since 1.10 are:
* Added -l switch to llogin to replace LF with VT
* Document -d -v switch to llogin
* Renamed PortSession to QueuedSession so it's less confusing
* /dev/lat ports connect using LocalPort and localportSession so they
  can share connections.
* Fixed spurious newlines generated by llogin -p

New features since 1.03 are:
* Can now handle multiple reverse-LAT connections via the same connection 
* Can specify a command to run (and user to run it under) for a named service.


This release also has some portability bits added, all the Linux-specific code
has been moved into interfaces-linux.cc/h so that people can port LAT to other
Unix systems - BSDs seem to be a popular request. Note that it will probably not
be me that does this porting but the new split should make this task MUCH easier
for those that want to have a go. I will accept patches from porters.

To use lat with a DS90L printer port you /must/ define the port as queued and
put the node name of the server in the latcp -A -p command. You can't use
llogin with DS90L printer ports.

I hope people find moprc useful - I certainly do!

Access to passworded services is currently only supported by llogin - if you
want this to be available from /dev/lat ports then let me know.

I regard this as a release candidate - if I don't get any serious bug reports
for this release then I will upload binaries, add it to the debian archive and
retire 1.03.

Thanks - first positive reaction:
Imedeatly after typing "echo ..." and hitting ENTER I got
a OPCOM-messages on my VMS-Systemconsole:

Massage from user DECNET on LA2161
DECnet event 4.18, adjacency down
From node 2.10 (LA2161), 11-FEB-2002 13:08:41.10
Circuit EWA-0, Adjacent node listener receive timeout

Few seconds later:
Massage from user DECNET on LA2161
DECnet event 4.15, adjacency up
From node 2.10 (LA2161), 11-FEB-2002 13:08:48.79
Circuit EWA-0, Adjacent node 2.50

I think I entered the next stage on the ladder:

After putting a name in node_name and eth0 in 
default_device I can connect with my LA2161 and
got - not a login prompt, but nearly.

sethost LA2161
sethost V1.0.3
Connecting to LA2161
Connected. Escape Secquence is ^[

... and no login prompt.

But I think there was a posting in the past describing
this problem. I will look for that!

Thanks at this point!

  ^^^ This is fine. If you want to set it though you can do
echo "FISH" >/proc/sys/net/decnet/nodname
for example.

> less default_device
> (nothing)
  ^^^^^^^^^ This you'd normally set to your default ethernet card and in
  endnode mode this is consulted in the case that you are trying to connect
  to a node from which no hello message has been received and when no
  default router can be found.

> less node_address
> 0.0
  ^^^ This is what is probably causing you trouble. Its usually best to set
  this with either module options or on the kernel command line depending
  upon whether DECnet is a module or built in. There are some hints in the
  linux/Documentation/networking/decnet.txt file.

The address set here has to match the DECnet address set in the MAC address
of your ethernet card before it will work. This address has to be set first
which is shy its best to do it via parameters when the DECnet subsystem is
first initialised,

Steve.

I've changed my /etc/sysconfig/network-scripts/ifcfg-eth0 to

DEVICE="eth0"
BOOTPROTO="dhcp"
ONBOOT="yes"
MACADDR=AA:00:04:00:32:08

IPXPRIMARY_802_3="no"
IPXACTIVE_802_3="no"
IPXNETNUM_ETHERII=""
IPXPRIMARY_ETHERII="no"
IPXACTIVE_ETHERII="no"
IPXNETNUM_SNAP=""
IPXPRIMARY_SNAP="no"
IPXACTIVE_SNAP="no"

Then I've done init 1 and init 3 for a complte reload. 
There is still no right entry in /proc/sys/net/decnet:

less node_name
???
less default_device
(nothing)
less node_address
0.0

I've tryed init 1 and start decnet manualy - 
starting decnet [ OK ]

In /proc/sys/net/decnet still the same wrong entries.

A complete reboot brings no better results.

Any further hints?

It is being called too late in the startup sequence. you must start DECnet
before TCP/IP because it needs to change the MAC address of the ethernet card.

The recommended thing to do on Red Hat is to edit the file 
/etc/sysconfig/network-scripts/ifcfg-eth0 to contain the correct MAC address - which
in you case is AA:00:04:00:32:08. See http://linux-decnet.sourceforge.net/faq-4.html#ss4.1
 
The Red Hat scripts are rather out of date these days I'm afraid - I don't run
Red Hat so I can't really maintain them very well.

[Linux-decnet-user] unable to start decnet

[Frank S. <FSa...@ha...>]

Hi,
I have trouble with the installation of DECnet for Linux.
I=B4ve an AS600 5/333 with Redhat 7.1. I=B4ve downloaded
the kernel 2.4.9.-21 from RH and build my own with support
for DECnet.

After that I=B4ve installed dnprogs-2.17-1.alpha.rpm and made
the configuration:
less /etc/decnet.conf
#
#               DECnet hosts file
#
#Node           Node            Name            Node    Line    Line
#Type           Address         Tag             Name    Tag     Device
#-----          -------         -----           -----   -----   ------
executor         2.50           name            declin  line    eth0
node             2.10           name            LA2161
node             2.20           name            LA2162
node             2.51           name            majest

BTW: Is it nessesary to have the user patrick?

After reading some older postings in the mailinglist I found that
I=B4ve forgot to install compat-libstdc and ncurses. I did it.

After that I still have problems to start /etc/rc.d/init.d/decnet:
/etc/rc.d/init.d/decnet start
Starting DECnet: Error setting hw address on eth0: Device or resource b=
usy
Error setting hw address on eth1: Device or resource busy
error starting socket layer.

Trying to connect brings:
sethost LA2161
sethost V1.0.3
Connecting to LA2161
socket: No route to host

Looking in /proc/sys/net/decnet:
less node_name
???
less default_device
(nothing)
less node_address
0.0
less debug
0
less di_count
3
less dr_count
3
less dn_count
1
less dst_gc_interval
2
less time_wait
30
less no_fc_max_cwnd

Looks not quit well, right?
