The fwohci device driver first appeared in FreeBSD 5.0. It was added to NetBSD 4.0.
AUTHORS
The fwohci device driver was written by Katsushi Kobayashi and Hidetoshi Shimokawa. It was added to NetBSD 4.0 by KIYOHARA Takashi.
BUGS
The driver allows physical access from any node on the bus by default. This means that any devices on the bus can read and modify any memory
space which can be accessed by an IEEE 1394 OHCI chip. It is allowed mostly for sbp(4) devices. This should be changed to allow it only for
specific devices. Anyway, IEEE1394 is a bus and not expected to be connected with un-trustable devices because a node can monitor all the
traffic.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat

sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.

Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.
