[9fans] [9fans ] What's the best access method to Plan9 from Linux

[Hongzheng Wang]

Hi all,

Currently, I installed a Plan9 system on a computer while I still
usually work under Debian Linux running on another computer.  So I
wonder how I can conveniently access the Plan9 system from my Linux
box?  That is, what is the best way to access Plan9 from Linux?  SSH?
or any other more Plan9 welcome methods?  And, of course, I have tried
to learn them from Plan9 wiki but feel yet difficult to understand
some concepts there, such as u9fs etc.

BTW: I have used ``Plan9 from user space'' port on my Linux box for a
while.  Is it useful to meet the mission mentioned above?

Thanks.

That makes me think that if there was a C to dis compiler, a full
plan9 fs (with its /dis/bin, /dis/lib) could be used from inferno.
Probably, as usual, many people know the reasons of not having such a
compiler. I don't. :)

I think the simplest way would be:

Configure your Plan 9 box as a CPU server which should be described
here
http://plan9.bell-labs.com/wiki/plan9/Configuring_a_Standalone_CPU_Server/index.html
and use drawterm to connect to it:
http://swtch.com/drawterm/
from drawterm you can access your local fs in /mnt/term so you can
copy things back
and forth also.

That's really two questions:
1) Why no C to dis?  There are a lot of reasons why C is
not a good fit to dis or to Inferno, for that matter,
not the least of which is C's ability to take the address
of an arbitrary object (not in the OO sense, but saying
thing all the time gets old).  Between that and the ability
to cast between integers and pointers, it's pretty much
impossible to do all your memory management with reference
counts and garbage collection, and Inferno doesn't have
a system call for arbitrary memory allocation.  There is,
however, a C to Limbo translator.  It doesn't do a complete
translation, but it takes care of a fair amount of the
tedious stuff and leaves you with some Limbo you can then
clean up.

2) I'm not quite sure what you mean by a full plan9 fs.
Do you mean like kfs or fossil/venti?  If so, then Inferno
does have its own version of kfs.  It can exist in another
file or on a disk partition quite happily.  It doesn't
do write buffering at the moment, so it can be a little
slow, especially during an install, but it does seem to
work pretty well.  In fact, if you're sufficiently bored
and a danger seeker, you can try my ISO image for a native
install.  It's a bootable CD image that will do an install
onto a disk and leave you with a system that will boot
straight into Inferno.  Be forewarned, there are a number
of limitations to the installation scripts that I haven't
had time to work on.  But if you want to give it a try,
