i don't think a direct mapping of COM to Plan 9 fs model is
unnecessary. for example, instead of mapping every control or
configuration interface and method to synthetic directories and files,
a single ctl file will do.

Is anybody else currently using the ethervgbe driver? I'm had some
problems with it which don't seem to be caused by my hardware.
After receiving 256 packets I was getting:

Turns out calling freeb was messing
I had the same problem and came to the same (kludgey) solution. The
ethervgbe driver is still a bit of a work in progress. Other ethernet
drivers use the same trick, a pool of Blocks that are never freed, but
they use _xincref inside the driver proper to make sure etheriq(...,
1) doesn't cause a
That's the wrong fix; ethernet drivers should always call
etheriq(edev, block, 1);
The sole exception is in devether.c.

Hello,
I've been wondering.
The plan9 'replacement' for the (linux/unix-like) find command, according to
the faq, is, in a way,
grep foo `{du -a . | awk '{print $2}'}
Now I want to find all files containing foo.
Is it so that `{ ... } produces the full list first and only afterwards this

Isn't it that this finds files whose filenames contain foo (like

I want files inside which there is foo somewhere...

Assuming that's true, couldn't you do some kind of trick to break it up
If looking through code:
du -a . | xargs g pattern [2]/dev/null
If looking through all files:
du -a . | xargs grep -n foo [2]/dev/null
The -n is to be friendly with acme.
This presumes you have (at least a cheap knockoff of) xargs.
Building a large list in advance can exhaust main memory on smaller terminals.

posted won't do the job, and the problem is not related to find at

On unix systems I tend to use find a lot, and in ways that aren't

say combining -prune, -type, -newer, and -exec, is nearly impossible
to do in a correct and efficient way without find, even if you have

Hi Newsham,
Is OpenSSL necessary for authenticating to 9P servers?
Currently, I get a failed to mount ...: 22 botch error when
trying to authenticate. Also, is it necessary to compile ninefs
with OpenSSL, or will the pre-compiled binary find and use
c:\openssl if it's there?
Thanks,

Does this answer Ron's question as to why one wants things added to
the distribution, not just tacked onto any old branched version?
++L
it would be better to create a /cfg/example.auth/cpurc that includes
keyfs and trusted services in it and remove them from /rc/bin/cpurc,
since they come after /cfg/$sysname/cpurc is run.
You could submit a patch...
I have a feeling that the philosophy is for /cfg to be entirely
optional, so
