Most of these can be attributed to the crappy wall wart they call a
power supply. If it's plugged into an UPS or replace it with your own DC
power supply they generally hold up a lot better.

I picked up a nifty little D-Link DSS-5+ 5-port 10/100 switch today
CompUSA had a 5-port network kit labeled 'DFE-910' which had the
DSS-5+ and two DFE-530TX+ NIC Cards ('rl' driver), plus cables, for $130.
It appears to operate quite nicely. I can run all 5 ports at
100Base
We have come across a problem wrt to a network file lock manager.
Consider the case of a lock on a local file, and a request from a remote
machine to lock that same file. fcntl(fd, F_SETLK, &fl) will return
immediately with EAGAIN (this is for an exclusive case, of course),
F_SETLKW will block

I would like to get my /usr/ports over a read-only NFS mount. At the
moment the only way I can compile up any given port is to mkdir work
and create and mount an MFS filesystem over it. A union mount might also
work but union mounts are still somewhat problematic.

I'm aware of boxes having been tested to ~100,000 connections if my memory
serves correctly. I know
Natd does not handle pmtu discovery well when the mtu for the interface
it is using is changed, either manually or under program control, after
natd is started. The following provides details of why, and a work-around.

I've started a side project that I'm trying to figure out how to scale. The
end result will be a test-based realtime chat (IRC, java, or otherwise) that

I have looked at the KLD examples and found out that they boils down to a
DECLARE_MODULE() macro with the subsystem given as SI_SUB_DRIVERS. Is
there any reason for using this particular SI_SUB_DRIVERS? I see another
example at http://www.freebsd.org/~abial/ that uses SI_SUB_EXEC.
