[9fans] exportfs / u9fs / v9fs / npfs / spfs versus 9vx

[9fans] exportfs / u9fs / v9fs / npfs / spfs versus 9vx

[Daniel Lyons]

Here's my situation: I have a FreeBSD VPS somewhere in the world. I
have 9vx locally. I want to access files on the FreeBSD VPS from my
9vx running over here. How?

 - exportfs doesn't exist in p9p.
 - u9fs seems to be defunct; there's nowhere to download the source.
 - v9fs seems to be Linux-only.
 - npfs seems to be nothing but an umbrella for spfs.
 - spfs seems to build a binary "ufs" which, no matter how I run it,
   exits right away. Did I miss some documentation?

What's going on? It feels like I'm missing some obvious trick.
Security for this operation would be nice, but I don't consider it
necessary.

Thanks,

This is the basis of the OpenBSD port.

unix/9pfreebsd is really too old to be useful but may be one
can start a new FreeBSD port from the openBSD bits?  I'd be
interested in such a thing.

It compiles w/ 2 warning messages on my machine. Setting it up is
turning out to be interesting. I think probably the safest thing for
me to do would be to try tunnelling it over ssh, since both host
operating systems can do ssh v2. Still hammering on it. It does look
like 9vx isn't really able to talk to the machine from here, which is
odd because p9p's srv seems to be able to, at least make the
connection, though I'm not having much luck with that either.

How are you guys using these tools?

I connect to unix machines from Plan 9 by installing fgb/openssh
from contrib, binding /386/bin/openssh over /bin, and then using srvssh.

The command line looks something like this:

srvssh sl@phoenix phoenix && 9fs phoenix

This mounts u9fs running as user sl on host phoenix in /n/phoenix.

Alternately, taruti's scpu (ssh2 client written in go) can be used:

srv -s 5 'scpu -u sl -h phoenix -notty -c u9fs -u sl -na none' phoenix
/n/phoenix

scpu is available here:

https://bitbucket.org/taruti/scpu

[andrey mirtchovski]

> How are you guys using these tools?

it's not the most sophisticated setup, but it works, at least for the
stuff that i need. pycrypto is a prerequisite:

----
hg clone bitbucket.org/f2f/py9p
python setup.py install
localsrv.py -p 10000

then in 9vx:

% srv tcp!127.0.0.1!10000 blah /n/blah
post...
% cd /n/blah
% ls -l | grep mach_kernel
--rw-r--r-- M 19 root   wheel 18694040 Jan 29 16:18 mach_kernel
%

if you want a more modern language and a faster implementation:

goinstall go9p.googlecode.org/hg/p/srv
cd $GOROOT/src/pkg/go9p.googlecode.org/hg/p/srv/examples && make ufs
./ufs -addr=":10000"

then in 9vx:

% srv tcp!127.0.0.1!10000 blah /n/blah
post...
% cd /n/blah
% ls -l mach_kernel
--rw-r--r-- M 19 none none 18694040 Jan 29 16:18 mach_kernel

i use u9fs regularly; i install it on any unix machine i'm required
to care about. these days that's only os x boxes, and the source
in the distribution builds without issue for me there. i can dig up
the configuration if that'd be helpful, but it's for launchd (apple's
inetd replacement). i believe a few folks have posted examples
to 9fans in the past.

u9fs has the advantage of doing (most of) plan9 auth, which is
often neglected by other implementations. it's a bit weird (you
store a key on the server, which means you likely want to
create a new user for that purpose), but it works.

the wiki's been misbehaving the last few times i've tried; if it's
better, i'll document what i did there.

I was thinking of a kernel port (mount_9ufs etc). My hopes
were briefly raised until I realized the openBSD port is not a
kernel port. Though I am not sure if a kernel port is worth it
(and it is certainly a bunch of work).

Wouldn't this be for mounting 9p *from* BSD, not exporting BSD's FS *to* 9p?

Have you had trouble getting to u9fs from 9vx? It seems to work from
p9p, but not from 9vx. Every connection to my machine times out, but

i haven't used u9fs in a very long time. i'm normally talking to
synthetic file servers written using py9p or go9p. i periodically try
to ensure that py9p and go9p are still able to converse with plan9
mostly out of habit.

I'm also not having any luck with py9p. So, there seems to be something wonky between 9vx and my FreeBSD VPS. I can imagine two possibilities:

1. My VPS or hosting provider has some kind of obnoxious firewall between me and 9vx
2. 9vx has to be set up somehow to access it

The problem with #1 is that I can access it from p9p on the same machine as 9vx, and the problem with #2 is that I can access sources without any trouble.

Anybody know what I'm missing, or have a good idea how to debug it?

Thanks,

no. in 9vx:

term% ls /n/biglin
/n/biglin/bin

/n/biglin/cdrom

/n/biglin/lib
/n/biglin/lost+found

biglin is a linux system (ubuntu 11.04) running u9fs.
that one's using authrhosts.

this one is a linux system on a remote virtual server
(kvm) running debian, and u9fs using authp9any:

Works for me: I use it with over SSH1 channel to mount AIX and Linux files.
Excerpt from /rc/bin/9fs:

	srvssh -r -u bin/AIX/u9fs $1 $1.$user /n/$1
