Has anyone written any code to deal with SCPI, Standard Commands for
Programmable Instruments, on plan 9?
https://en.wikipedia.org/wiki/Standard_Commands_for_Programmable_Instruments

I have a few instruments and just bought a cheap Kiprim Programmable
DC power supply which works with 9front's nusb/serial. I poked at it a
bit using con and rc and it works rather well. I also bought a Bertan
high vintage supply that features GPIB but I do not yet have a GPIB
adapter.

Subject: RUDP and/or others

I know this is from a thread almost 8 years old on 9fans.

I'm ignorant of why RUDP wasn't used in lieu of TCP for 9P
connections.  Anyone know the whys and wherefores (either technical,
historical, or political)?  I had read earlier that TCP was used in
lieu of IL (another transport protocol developed for Plan 9) due to
performance over long-distance connections.  Did RUDP just not cut it
in some other way for the needs of sending/receiving 9P messages?
From the description in ip(3), it seems to have the nice behavior of
resuming communication when a machine reboots.  Is it due to the
middle boxes/firewalls that are present in present-day networks?

Hi people,

I have had to renew my certificate for tls and am getting a strange error from imap4d
when trying to collect email from my iphone.

	tls reports failed: factotum_rsa_open: no key matches proto=rsa service=tls role=client 

Which does not make sense to me as my factotum has my new ras key in it:

	key proto=rsa service=tls role=client owner=* size=2048 ek=10001 !dk=...

I have also put the same key in bootes factotum so it can be used for smtp outgoing mail, and rebooted to populate bootes factotum.

I have updated /sys/lib/tls/mail.pem, I even remembered to import the PEM
certificate (profile as apple calls it) into my phone.

What have I missed? why can't tlssrv find my key in my factotum?

-Steve

 I'm a CS student at National University of Singapore. I came through the
GSoC project ideas of Plan9 and I'm interested to know/learn about
implementing 9P in Dart.

I mainly wanted to ask you the following question:
1. I read few papers for understanding the basics of Plan9, Inferno and 9P.
I wanted to know whether you could suggest me some pointers/references
specifically related to implement 9P in Dart so that I can start
working/learning along those lines.

I hope to get a reply from Charles Forsyth, the mentor of this project. It
would be really helpful and great if others also drop by to give their
advice/suggestion.

Thanks and Regards,
Ashish

For my next homework in my Operating Systems class, the professor has
assigned the equivalent of a simple libthread.  I’ve been looking
through the libthread code and getting lost ☹.  I don’t need procs,
only threads (except for the oh-so-fun complication of user-level
pre-emptive scheduling, but I can worry about that mañana).  I do,
however, need to create per-thread stacks, probably by massaging
jmp_bufs in malloc()ed memory.

Where in libthread does the stack get set up, and could somebody
please give me a high-level overview of what the code is doing?

Thanks, --Joel

Hi all:

Just got the Dec 30th version of Plan9 up on my home computer
and i may be trying it at work on a spare PC. At home i have not
been able to get networking up with a sis900 nic card. I have a
compatible card ordered, but can anyone give me some pointers so
we can get this computer on the net before the new card arrives.

Thanks in advance

Marina Brown

* [9fans] cpuserver: dhcp for authsrv, rio, users, ssh, factotum, pull
@ 2004-07-03  7:17 Stephen Wynne

From: Stephen Wynne @ 2004-07-03  7:17 UTC (permalink / raw)
  To: Fans of the OS Plan 9 from Bell Labs

I'm attempting to setup both a cpuserver and an authserver on
one system. I'd like it to be a terminal, too.

First, I more or less followed the advice on it at
http://www.cs.bell-labs.com/wiki/plan9/Configuring_a_Standalone_CPU_Server
while also looking at
http://pages.cpsc.ucalgary.ca/~mirtchov/lanlp9/4e/cpuauth.html

This may sound funny, but can I setup a CPU server, auth server,
and terminal all on the same system and have it all configure
itself dynamically based on a DHCP IP address?

Although my system worked just fine from the gnot install defaults,
after converting to a cpuserver,  I got this:

    RIO says: aux/vga: mga2164w: can't set mga type
    rio: can't open display: initdisplpay: /dev/draw/new: no framebuffer
    init: rc exit status: rc 12: rio 13: display open

Adding lines of display setup logic from from termrc didn't help.

I am unclear what passwords to assign to secstore and
bootes as I'm setting up the authserver for the first time.
I'm also unclear what the difference is between bootes
and other users I might create after this.

Also, SSH fails to connect now that I've rebooted and
setup bootes as the terminal "owner" (if that's the right term,
pardon my pun). I figure something must be haywire
in my authentication (Factotum?). Following instructions at
http://pages.cpsc.ucalgary.ca/~mirtchov/lanlp9/tips.html
I figured I should combine both authserver and terminal
instructions. I get:

    cpu% auth/secstore -p /tmp/factotum
    can't dial tcp!$auth!5356
    secstore authentication failed

Out of curiosity, I tried to do a pull to update my system.
That didn't work, either. I was running as bootes connected
through drawterm:

cpu% /usr/glenda/bin/rc/pull
post...
srv tcp!sources.cs.bell-labs.com!9fs: mount failed: authentication failed
bind: /n/sources/plan9: '/n/sources/plan9' does not exist
servermount: bind 363: bind
cpu% 9fs sources
srv tcp!sources.cs.bell-labs.com: mount failed: authentication failed

I apologize for asking so many questions at once, but there
doesn't seem to be a true cookbook recipe posted on just
how to do this with all the obvious steps included for mortals
like me.

One problem I hit was trying to setup fossil by default on this
system. There were exceptions to the flow of the normal KFS
setup that threw me off and I was in a hurry.

I have something else I want to do that I was almost able to do
with a plain KFS gnot install, so I'm tempted to just do it
over again and get back to that...

By the way, can I reboot a system from drawterm and how would I
do that?

My cpurc is at http://www.place.org/~stevemw/junk/cpurc
The ftpfs command is really handy!

i lost the magic russ gave me.  my 505 had the odd gravity accident,
then sony smashed the mother board when all they needed to do was
to replace the keyboard, but i did have it booted.  then i hit azerty
hell and i sort of gave up in disgust because of the amount of kernel
hackery i would have to do to type stuff and then be able to back up
what i'd hacked looked prohibitively dangerous.

smashed file-systems -- not my thing.

iirc you just need some plan9.ini magic.

i have a Z600-LEK now, bought after the second gravity accident.

i might put plan 9 back on my 505, but i have other more pressing
issues and from what i've seen of the keyboard driver (if i understand
it right) it will need major surgery to support azerty.  screw that
up and you have the odd problem.

those vaios are cool, but weird.  shame you can't buy 505s anymore.

I don't like the brackets either, but postmaster@cse.psu.edu decided they
were cool, and so every mailing list gets them, despite local opposition.

    Boyd: I imagine that it wouldn't be hard for you to strip
    out the "[9fans]" with procmail or similar. I can also imagine that
    given your correct headers, you probably get a lot of spam, and this
    is just the final straw on email hassle. :-)

i could strip it out, but that's not the point.  why strip out what
should not be there?  i do get a lot of spam, but i won't change my
address -- that would be giving in.

Boyd might not get complaints, but I certainly get them
about my X-Face header. Mind you, they're usually verbal,
and from the same person who has a remarkably short memory. :-)

Plus, some people have assumed that the X-Faces header is just
corrupted data, or have confused it with the gumph that some
over-enthusiastic MIME mailers insist on chucking in (M$ Exchange,
I'm talking to *you*).

wrt "[9fans]", it's an interesting issue. Ok, so many can't change
their broken mailers, but I've generally assumed that most of the
readers on this particular list are in a better position to affect
or fix their environment. This is a false assumption, as shown by
jim's comment on unix support and news/mail access earlier this
week. Boyd: I imagine that it wouldn't be hard for you to strip
out the "[9fans]" with procmail or similar. I can also imagine that
given your correct headers, you probably get a lot of spam, and this
is just the final straw on email hassle. :-)

Personally, I don't care either way. I imagine the Reply-To is far
more contentious (and don't care either way on that, either; there
are cases when I want both settings).

According to Boyd Roberts <boyd@france3.fr> :

> is this [name] nonsense in the Subject: line some kind of disease?

I find it useful, and users of a number of mailing lists off my system
have voiced no objections.  I also enjoy the X-Face header line you
use, but I can imagine objections to that too.

Most useful, the mailing list indication makes it easy to group
messages using the obiquitus "Subject:" line sorting, whereas there is
little in the line of consistent sort algorithms that will work
reliably for any other header line (or message contentsm for that
matter).

I don't think broken mailers come into the picture at all, and in any
events, not everyone is in a position to repair their mailers.

this is the second mailing list i'm on that has succombed to this
majordrongo madness.  i know it's 9fans from the To: and the Cc: lines.
i have heard that the rational is for those who have broken mailers.
they should fix their mailers, not break the list.  braindamage should
not be propagated.
