On the topic of switches...
Does anyone have experience (good or bad) with the CNet
CNSH-1601 or CNSH-2401? Those are unmanaged 19" switches
(10/100) with 16 and 24 ports, respectively, and a
100BaseFX (fibre) uplink port. And they're suspiciously
cheap over here [1].
We might get one of those

You usually find this capability on managed switches (fairly obvious,

Hello all,
After creating some larger slices than I'm used to, I finally felt the
full force of a default 8% minfree setting. So, I went to tunefs(8) to
try and put a damper on the multiple gigabytes that aren't being made
available to users. However, I was a bit disappointed to note that

Hello,
I'm little confuse to using splimp/splx in driver
that support PCI board. IRQ is shared for PCI.
Is using splimp can cause for some problem?
Thank a lot

Hi!
Say I want to change the man colors when I read mans at the console. More
precisely, I don't like that underlined text shows up as reversed (black
letter on while(grey,7) backround). How (and where) do I need to say that
I want, say, yellow on black instead of reversed when displaying

There isn't. All i386 mem is DMA-able. I still have to make things work
with bus_dma and friends.

Your register read will take at least 1msec. That is the time between
scheduling the transfer and the interrupt being triggered for
completion.
But typically it will take 2msecs.

It isn't. You don't want to be polling for 2msecs for every register

Is there such a thing called "user-level asynchronous i/o" in FreeBSD? I
assume that the aio_read(), aio_write() stuff is kernel-based asynchronous
i/o. SIGIO is also a kernel stuff.
Thanks for any enlightment.

Even something as lightweight as a thread is still too heavy for large
systems.

I am looking for some routines to perform DES encryption in electronic code
book mode.
I have found the ecb_cyrpt function, however when I try and use it the
buffer is not encrypted.
Am I missing something, do these functions not work, and is there a better
way of doing this?
Below I have included

When can I call kthread_create? I tried in the driver attach, but
that failed in fdcopy() calling vref with a NULL pointer. I tried
calling at the end of config (in config_intrhook_establish called

Hi there,
I've recently had .. ahem .. fun trying to get my headless FreeBSD box to
spit messages at the console. I've got the kernel doing it right, but not
the boot loaders. The boot loader will print to the serial device - but it
won't load my kernel :-( I haven't exhausted all oppurtunities h

Yes. Another FreeBSD machine, with an ethernet interface and a parallel port
for running PLIP over. They are kind of large, though.
To whom do I send Kudos for Applixware?

I have made a small patch (about 10 lines of code) to "cron" that lets
people choose between localtime and gmtime for their crontab entries.
The choice is made depending on the setting of an environment variable
in the crontab file. The cost is a factor 2 for the tiny amount of work
that cron does
