As far as I understand once the probe function(Not too sure) detects
or kernel detects then the driver would be looked up
and control would be handed over to driver.
If this is correct then how does probe works? Or how a particular

Hi,
wanted to know if the information given on this link is still valid.
http://linuxgazette.net/93/bhaskaran.html
Since I am new to programming network devices on Linux so not clear with it,
I have looked at Chapter 17 of LLD 3rd edition.

In the file include/linux/inetdevice.h
struct in_device has a member cnf which is set to 1 when IP
Forwarding is enabled in Linux Kernel
cnf is a struct of type ipv4_devconf so what does this mean that the
member cnf is set to 1.
I am not able to understand how can a structure be set to 1?

iw_handler is the type. For example:
int do_something(struct net_device *dev, struct iw_request_info *info,
union iwreq_data *wrqu, char *extra)
{
/* do stuff */
I was reading an article
http://www.linuxjournal.com/article/1221
They have used get_user_byte and put_user_byte
functions do they exist?
I tried to man them but there were no entry.

I restart ssh on Ubuntu 10.04 64 bit server edition and I see
following line in auth.log
sshd[5678]: error: Bind to port 22 on :: failed: Address already in use.
when ever I restart ssh I see the above line.
That is a headless server.

I am using denyhosts on a server ( I know IPTABLE rate limiting etc
just testing this one)
so in a config file
/etc/denyhosts.conf
the following value is set
DENY_THRESHOLD_INVALID = 3
which as per their configuration file says
DENY_THRESHOLD_INVALID: block each host after the number of failed log
101 - 200 of 568 matches
