[9fans] 9P on linux

[9fans] 9P on linux

[jhutchence]

I am having trouble getting 9P working on my linux box. Firstly u9fs:
I have followed the directions on http://www.t3x.org/bits/plan9_on_u9fs.html
and put put this line in /etc/inetd.conf

u9fs    stream  tcp     nowait  root    /root/bin/u9fs  u9fs -Dz -a
p9any /scratch/p9root

the only client I have even been able to run is this one:
http://www.lava.net/~newsham/plan9/

when I try to connect with it using: ./cl.py glenda localhost
I get 'localhost: Connection refused'

this is my /tmp/u9fs.log:
u9fs
kill 24633
<- Tversion tag 65535 msize 16384 version '9P2000'
-> Rversion tag 65535 msize 8216 version '9P2000'

00000000 00000000 00000000 00000000'
u9fs: couldn't read message
last unix error: No such file or directory

I have created a user called 'glenda' with password 'glenda' and
copied that into /scratch/p9root/etc also I have created /scratch/
p9root/etc/u9fs.key with:
glenda
glenda
local

I have also tried various combinations of usenames and passwords and '-
a none' for u9fs in inetd.conf none of which has worked.

Secondly, when I have tried the 9pfuse client I get this:

root@box:~/9pfuse# ./9pfuse 'tcp!127.0.0.1!564' /mnt
error: fid unknown or out of range
connect error: fid unknown or out of range

I can't find any information on this error either. If anyone can help
with either of these problems, please do. If all you can say is "RTFM"
believe me I have RTFM many times and despite the supposedly simple
nature of these tools, they remain non-intuitive for a novice like me.

Probably is stupid but ...

after editing inetd.conf you reloaded the service with /etc/init.d/inetd
restart ?

slds.

This looks like things are falling down in auth.  Why don't you try an
unauthenticated connection first?

Harder to tell what is going on without any kind of log, but I'm
suspicious its once again some sort of auth problem.  You may want to
switch from u9fs to spfs (or one of the other servers).

 I'd recommend running with p9p[1] for testing. Here's my setup (wren
is the server, nightingale the client):
wren:/etc/inetd.conf:31:564     stream  tcp     nowait  root
/usr/local/bin/u9fs     u9fs -a p9any

nightingale$ 9 factotum
nightingale$ srv -a wren
Adding key for proto=p9sk1 authdom=sqweek.dnsdojo.org ...
User [sqweek]:
Password: *********

nightingale$ 9p ls wren/home
d-rwxr-xr-x M 0 sqweek  users 1024 Jan 10 16:43 sqweek

 Brief explanation - "9 factotum" starts up the password manager (for
lack of a better term), and "srv -a wren" starts an authenticated
connection to my server (via tcp on port 564, since I didn't specify).
Both of these commands place a socket in my 'namespace' directory,
/tmp/ns.sqweek.:0, for further communication. srv then communicates
with factotum to achieve authentication, and finally the 9p command
uses the "wren" socket that srv created. I also mount it with
9p2000.ko using "mount -t 9p -o proto=unix,noextend
/tmp/ns.sqweek.:0/wren /home/sqweek/n/wren".
