Re: [Linux-decnet-user] Supported linux systems?

[Bengt N. <ben...@ch...>]

Thanks for the info.

I am trying to set up a "intelligent terminal" to support a VAX hardware control system, where the main control is connected via a serial line. Decnet would be a significant enhancement to the work environment, since you could open several parallel connections without additional serial lines. The system has ethernet, but the VMS we have to use is too old to support ssh.
It is a multi-user system so I prefer Ubuntu since it is more friendly to the unix-illiterate user.

I suspect (I have stated this before) that my problem has to do with the Ubuntu "upstart" boot sequence, and it seems decnet is not started before tcpip. I am not compenent enough to control this, I guess someone who is should have a look at it and hopefully adapt the package accordingly. Or at least identfy what the problem is and suggest a fix if possible.

Anyway, whatever I do I get this message:

bnilsson@ubuntu:~$ dnlogin fyvax7
Cannot connect to fyvax7: Rejected by object

Is there ay way I can I invoke a more detailed error message?

Nothing is really 'supported' in the sense that you get guaranteed
response to problems. But if you just want a system that will run DECnet
then any Linux system will do.

It helps if the distribution ships with the DECnet kernel module, I know
that Debian and Fedora do and I *think* that SuSE used to. If you have a
distribution that doesn't then you'll have to build your own kernel. The
easy way to check for this is just to type "modprobe decnet" in a root
shell - if it doesn't return an error then off you go :-)

Debian also has the DECnet userspace programs packaged and part of the
distro and it's moderately easy to set up. As far as I know no other
distribution does this and there are no 3rd party packages that work.
Having said that, it's pretty easy to build the software from source.

The FAQ has some details about distriutions, but I'm not sure how
up-to-date it is, sadly.

What linux flavors are supported for running Decnet?

Obvously, Ubuntu seems not supported.
