Inappropriate ioctl for device
My host is using PHP Version 5.2.6, I have no control it's setup
There is something strange going on:
I pass a variable to a page with tables it works, pass the same to a
page using CSS <div> instead of <table> I get the warning PHP
"Inappropriate ioctl for device"
I am learning how to use CSS, PHP and templates which is supose to
simplify life. I is only making mine more confused.
The test site is at gasperaux.canadian-dream.com
The problem is with this script I think, it is identical in both file
since I cut and paste it.

I am getting this error in a standard ksh script
it really doesnt do anything fancy, so Im having
a hard time tracking it down.. My main clue is that
it does not happen when I run it on a different box
in a similar environment.. The only stty that the shell
sets is stty istrip.
Any ideas (or solutions of course ) appreciated (reasons

I have a python program that downloads database backups from a remote server, and tries to replace the local database with the downloaded backup. The database is a PostgreSQL server and my program calls the pg_restore command with the aid of the wonderful pexpect module. Everything works fine if I start this program from a tty. When I try to start the same program from cron, I get this nasty exception:
Traceback (most recent call last):

the shell passes terminal control to the background child process, the

I tried to install the port "sysutils/dvd+rw-tools" on a release 5.4 FreeBSD
box. The installation process seems to complete without error. But when I
tried to issue the command
to format a dvd+rw disk in the drive, I got the following error message:

I have verified with dmesg to make sure that my DVD+RW drive is at acd0.

I'm using the procedural upload() function from CGI.pm.
In this line:
my $fd_file = upload( 'file' ) or die( "upload() ( $! )" );
I encounter the weird-looking error:
"Inappropriate ioctl for device".
I don't understand what could be the problem. I did exactly like they
say in the manual.
Can you please help me solve this problem?
Thanks a lot!

I upgraded Perl from 5.6 to 5.8. The software I develop used to work fine with
Perl 5.6 and now, sometimes, I get the error "Unappropriate ioctl for device"

My Perl version is v5.8.0 included in the Debian 'sid' - unstable.
Does somebody have an idea ?

I'm a newbie at least for what regards these 2 topics and I'd like to
get some knowledge about them (as I found a lot of confusion around
which probably messed up my mind more than explaining).
In particular I have my kernel module for a network interface and I'd
wish it to communicate with the user space. I'd like to create my OWN
private IOCTLS which to use with my userspace app. I read around that
what I could try to do is create a character device and make the
kernel module and the app access it in read/write mode .. is this
possible ? how ? Example code is appreci...IOCTL problem for network device
Iam writing PCI device driver for the custom board that is
registered as network driver "zzz0" using register_netdevice() that
does bus master DMA data transfer.
1. In my driver, I could do DMA transfer (filling dma memory in
the kernel itself) data between pc to board and vice versa by
programming the memory mapped device DMA register.
Now what I want is that,I want the user application to fill the
dma buffer area through IOCTL and to start the transfer.
Iam not clear with copy_from_user/ copy_to_user with mmap()
function. I hope using mmap gives high preformance. Let m...device path for device
I have connected a new external tape device to my server , in another
server , I use the device path /dev/st0 for the internal device , but
I can't use the same device path for the new external tape device now
, are they different for internal and external device ? if yes, what
is the device path for external device ? thx in advance.

...call IOCTL for device from dpc?
can a dpc routine invoke an ioctl of some device ? if that is not possible,
then is it
possible that the dpc lowers the irql of the
processor , starts a system thread at PASSIVE_LEVEL which invokes the ioctl.
will this thread be scheduled by the dispatcher or start executign str8 away
the point that the dpc invoked it?
No. Just call ExQueueWorkItem from the DPC to call the IOCTL.
BTW - on what IOCTL you're speaking about?

I'm writing a driver module for a wireless interface (under linux).
The module is currently able to process the ioctls coming from
wireless tools (such as changing ESSID or freq etc...
I see that iwtools offer a set of "private" IOCTL numbers for driver
specific purposes (SIOCIWFIRSTPRIV).
What I don't understand is HOW to define my own *additional* ioctl
numbers and using them from the userspace.
I've been trying something like this in the kernel module:

#define USER_APP_IOCTL _IOWR(IOCTL_APP_TYPE,0, struct iwreq *...burncd: ioctl(CDIOCSTART): Device busy
I used to be able to burn CDs, but a couple of days ago, while I was

I'm wondering why, in order to talk to an net device, I need to open a

reasonable to me..
Thanks in advance!

- Why is $! getting set if the open was successful?
- My open command seems pretty darn simple. Am I doing something wrong?
- Is this a known issue?

Why do I get that error message? What's so busy, that a snapshot

I read somewhere, that a running NTP daemon might cause this
problem - but there's no NTPd running on that box.

...implementing ioctl's for device drivers
we are beginners in kernel programming. we are writing a device
driver. we tried a very simple ioctl to pass an integer pointer from

the problem is that the ioctl_param argument which is supposed to hold
the address of the memory in user space(from wer data is to be copied
to kernel space,i.e driver)is not getting passed correctly.
wen we print the address in user space & wen we print the address
getting passed to kernel space they r different. the correct user
space location is not getting accessed at all.

That is imposible.
You can get the device number by using the RAW_GETBIND
ioctl (like raw -q does). But there is no way to get
the device name from the device number (other than
searching through all of /dev and hoping to find the
