IEEE80211_CRYPTO(9) BSD Kernel Developer's Manual IEEE80211_CRYPTO(9)NAME
ieee80211_crypto_attach, ieee80211_crypto_detach, ieee80211_crypto_encap -- 802.11 WEP encryption functions
SYNOPSIS
void
ieee80211_crypto_attach(struct ieee80211com *ic);
void
ieee80211_crypto_detach(struct ieee80211com *ic);
struct ieee80211_key *
ieee80211_crypto_encap(struct ieee80211com *ic, struct ieee80211_node *ni, struct mbuf *m0);
DESCRIPTION
These functions provide encryption support for 802.11 device drivers.
The ieee80211_crypto_attach() function initializes crypto support for the interface ic. The default is null crypto.
The ieee80211_crypto_detach() function frees data structures associated with crypto support for the interface ic.
The two above functions are automatically called by the interface attach and detach routines, respectively.
The ieee80211_crypto_encap() function encapsulates the packet supplied in mbuf m0, with the crypto headers given the for node ni. Software
encryption is possibly performed. In case of no specified key for ni or multicast traffic, the default key for the interface ic is used for
encapsulation. The key is returned in the case of successful encapsulation, otherwise NULL is returned.
SEE ALSO ieee80211(9)HISTORY
The ieee80211 series of functions first appeared in NetBSD 1.5, and were later ported to FreeBSD 4.6.

IEEE80211_IOCTL(9) BSD Kernel Developer's Manual IEEE80211_IOCTL(9)NAME
ieee80211_cfgget, ieee80211_cfgset, ieee80211_ioctl -- 802.11 interface ioctl commands
SYNOPSIS
#include <net80211/ieee80211_var.h>
#include <net80211/ieee80211_proto.h>
#include <net80211/ieee80211_ioctl.h>
int
ieee80211_cfgget(struct ieee80211com *ic, u_long cmd, void *data);
int
ieee80211_cfgset(struct ieee80211com *ic, u_long cmd, void *data);
int
ieee80211_ioctl(struct ieee80211com *ic, u_long cmd, void *data);
DESCRIPTION
These functions are typically invoked by drivers in response to requests for information or to change settings from the userland.
The ieee80211_cfgget() and ieee80211_cfgset() functions implement a legacy interface for getting and setting 802.11 interface attributes
respectively. The interface is compatible with the RIDs implemented by the wi(4) driver and used by the wiconfig(8) utility.
The ieee80211_ioctl() function implements ioctls such as key management for wireless devices. Ioctls related to the Ethernet layer also pass
through here, but are handed off to ether_ioctl() when no match for cmd is found.

Introduction
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
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin
-r-xr-xr-x 1 bin bin ... (6 Replies)
I have a file which looks roughly like this:
996 mmmmmmm
996 xxxxxxxxxxxxx
99600 ssssssssss
9964 fffffffffffff
and would like to sort it numerically on the first field. I tried:
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)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.
I've got the Oracle installation guide for it and I got as far as:

I don't have a CD-ROM by that name and a web search for that... (21 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.
The prompt is... (2 Replies)
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. Now I had found a closed reference to adding time titled "add up time with xx:yy format in bash how?" In it, the example works great for that formatted list of times... This is the reply code...

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
