dell wireless keyboard/mouse package
I have recently set up FreeBSD on a Dell Inspiron 4600 and the wireless keyboard/mouse package that came with it has had 2 issues so far: --The keyboard tends to repeat letters when I type rapidly, but they don't repeat next to each other insead, one character apart. example: I type www.freebsd.org and what may come out on the screen www.frfeebsds.como It doesnpt always affect all the letters, and it seems that some, like 'a' and 'o' tend to repeat more often. --The mouse isn't recognised at all. The reciever hub is recognised (same as for keyboard), but the mouse doesn't act at all. Right now I am running a USB optical mouse, and my wireless is sitting off to the side, but it would be nice if I could get it back. Those are the problems, one other issue but not one that is annoying is that the reciever/hub is recognised as a logitec hub, not as a dell one. this may be because dell bought the logitech one and just redid the exteriors, but I thought it was odd that they wouldn't change things up...especially after seeing the way they messed with the SBLive! --Thanks --Dan _ Is your PC infected?

RE: quiet ATX mid-Towers
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of zera holladay Hello, I am looking for a very quiet ATX mid-tower and I was wondering if anybody has a suggestion or recommendation. My hard disks produce the most decibels at the most annoying frequency -- its not a bad fan. I am an EE student using FreeBSD, so a quiet computer is very important to me. Well, you could start by looking at http://www.quietpc.com/. I've bought various items from them and have been very happy with the result. Keep in mind however that no one thing will solve the problem. You need to replace everything that makes noise, right down to the fan on the northbridge if you've got one. You can get fanless cooling for everything, assuming of course your air temperatures don't regularly pass 30C. For the disks the best you can do is: 1) Put them at the back of the case, if you have a case that supports this (AOpen do some rather nice tower cases that do - their H700 series). 2) Isolate them with noise damping mounts - this however pretty much guarantees you can't put them in standard 3.5 slot. 3) Replace them with quieter drives. The newer Seagate drives are pretty good. -- Rob | Oh my God! They killed init!

ipfw2 test utility
Hello -hackers. I'm thinking about an utility to test a simple packet against the machine's firewall (ipfw2 to be more specific). I needed it because on some of my routers the configuration got complicated and the rule count is too high. And sometimes I need to see quickly what a colleague have done to the firewall and why it's not working as expected. Is there an (easy) way to take the packet-matching code from the kernel and use it to check a (manually) constructed packet on the current ipfw2 rule set? I was planning on writing a simple script that reads the output of `ipfw list' and then does some very simple checks. Mostly I need to look what's done to packets from certain address/network coming from a certain interface. Sometimes I need to check on tcp streams too. Maybe I should just write a good script to build proper rule sets and not try to fix a problem by creating more problems :) Any comments are welcome ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

lkm i/o port allocation problems
/*I am trying to figure out how to port over an infrared reciever driver
from linux to freebsd. i have been reading the developers book, as well as the
source for sio/ep and several other char drivers that use i/o ports. i can't
seem to get my i/o port allocation to work. whenever i request the region w/
bus_alloc_resource() it returns NULL to me the first time i load my module.
however, once i try again, i get the message:
ser0 at port 0x2f8-0x2ff on isa0
ser is the name of my module. so it seems that even tho the alloc call is
failing, somehow i still have the region to myself??? and now, even after i
reboot my computer, whenever i try to load my module i immediately get the above
error message. so it seems that somehow, even tho it is restarted, it never
lets go of the i/o region?? this module is not called at start time, it is only
loaded when i give kldload command
my other problem is that in order to get the probe/attach functions to be
called, i used the identify function in which i call the BUS_ADD_CHILD()
function as i saw ep driver do. is this correct? b/c after i load my module
once, the next time i try to load it this call always fails. is this correct
way to do this? if not, how do i get the probe function to be called, b/c it
wasn't being called when i loaded my module. here is the code, it is very short
as i chopped out the extra stuff. if someone could please take a quick look im
sure it would be obvious what i've done wrong, but i can't see what the problem
is. i've been digging thru the resource allocation functions and they're just
to complex for me to understand atm. thanks very much for any help.

Note for the impatient: This message does not discuss the well-known
issue of reusing local addresses through setting SO_REUSEADDR. This

Attached below is a patch addressing the issue of the inability to
reuse a local IP:port couple occupied by an established TCP connection
from another user, but by no listeners. Could anybody with fair
understanding of our TCP/IP stack review it please? Thanks.
[...]
One more detail to note:
Currently if another user's socket is in the TIME_WAIT state, it
still counts as occupying the local IP:port couple. I cannot see
the point of such a behaviour. Restricting bind() is to disallow
unprivileged port stealth, but how can one steal a connection in
the TIME_WAIT state?
For FreeBSD-4 the above patch would take care of this case along
with established connections, but in CURRENT TIME_WAIT connections
are a special case since they no longer use full-blown state.
Therefore, for CURRENT the above patch mutates into the below one.
[...]
Since I've got no feedback on this issue, I have little hope that
someone will pay attention to my next patch ;-)
However, I have no experience with IPv6, so currently I've got
no choice but to offer my patch for your review, friends, so that
some kind person might take a glance at it while I'm exercising
myself over IPv6 ;-)
I made this patch by analogy with the IPv4 one, which is already
in the CURRENT kernel--luckily, the IPv6 code is rather comprehensible.
It addresses the same issue I was talking about a month ago, but
for the IPv6 stack: It enables the non-root reuse of local address:port
tuples occupied by established or TIME_WAIT TCP connections from
other local users, as long as these particular cases have no security
implications a.k.a. port theft.

Ntop 3.0 and Shared Library Problem
Hey Im running FreeBSD 4.9, and ive installed ntop-3.0 from Ports. Now ive had issues with this before, so i decided to remove any and all old packages, and all duplicate packages, and all dependencies that ntop has that were out of date. I then reconfigured and re-built and installed ntop from scratch. I fixed all the config errors that appeared and all options i wanted. And i built and installed ntop with both dynaic plugins enabled and --enable-static-plugin option. I have also checked that all the permissions for all the plugins and directories and everything was correct. But no matter what i do, i still get this problem. Sat Jun 19 15:55:45 2004 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/netflowPlugin.so' entry function [Invalid shared object handle 0x28070900] Sat Jun 19 15:55:45 2004 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/nfsPlugin.so' entry function [Invalid shared object handle 0x28070c00] Sat Jun 19 15:55:45 2004 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/pdaPlugin.so' entry function [Invalid shared object handle 0x28070f00] Sat Jun 19 15:55:45 2004 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/rrdPlugin.so' entry function [Invalid shared object handle 0x29b90200] The odd and strange thing is, i have a few other FreeBSD 4.9 Servers, where ntop compiles and installs the same as above, with no extra things needed to be done, and no other configure options passed, and ntop compiles and runs perfectly without a single one of the errors above. Some of the other freebsd servers where ntop works fine, is the exact same hardware as the one above where it doesnt work. If anyone has any ideas or any suggestions, i am willing to try anything.

/bin/ls sorting bug?
Hi all,
ls(1) says that the -t option will:
Sort by time modified (most recently modified first) before sort-
ing the operands by lexicographical order.
which I take to mean that items (in the same directory) with the same
timestamp should be further sorted according to their names. Unfortunately
it doesn't really work that way:
(562) tuatara:/tmp/foo $ ls -lt
total 0

This is on a 4.10-PRERELEASE machine, but the -CURRENT code seems to be
identical as far as sorting goes.
Is this intended behaviour? If so, the documentation is wrong. Otherwise,
the attached patch produces the expected output. I can commit it if there
are no objections.

Re: dell wireless keyboard/mouse package
I have recently set up FreeBSD on a Dell Inspiron 4600 and the wireless keyboard/mouse package that came with it has had 2 issues so far: --The keyboard tends to repeat letters when I type rapidly, but they don't repeat next to each other insead, one character apart. example: I type www.freebsd.org and what may come out on the screen www.frfeebsds.como It doesnpt always affect all the letters, and it seems that some, like 'a' and 'o' tend to repeat more often. I'm getting this same problem on my Dell Inspiron 8100 keyboard with no FreeBSD and no wireless involved. I guess that doesn't help you. I'm just saying it might be hardware. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Of course, sorting on the (non-displayed) nanos field could also produce such unexpected output as you describe.

Re: lkm i/o port allocation problems

Do you have another driver at this range of ports? It is on my
machine:
sio1 at port 0x2f8-0x2ff irq 3 on isa0
so you have to ensure that you don't have sio binding to this device.
You'll get bus_alloc_resource returning NULL in this case.
: ser is the name of my module. so it seems that even tho the alloc call is
: failing, somehow i still have the region to myself???
I don't understand this statement at all. Just because the ISA bus
thinks your driver might have the resources, doesn't mean that your
driver actually has them. The information is there because many
devices might be at the same location (think aha and bt).

What error message. You included none in your comments.
: so it seems that somehow, even tho it is restarted, it never lets go

Maybe sio1 has claimed this device already. Maybe your system has
pnpbios/acpi listing the device? That's the usual reason...
: my other problem is that in order to get the probe/attach functions to be

No. You don't have to do this. In fact, you shouldn't generally do
this in your driver. You should either bind to the PNP ID (which gets
reprobed on every driver add), or you should add hints to the boot
loader.
: b/c after i load my module
: once, the next time i try to load it this call always fails.
That's because one usually doesn't need to do this :-).

: DEVMETHOD(device_attach,ser_isa_attach),

You rarely need identify. In this case it is contraindicated.

Don't use uprintf. You will find that when you add the driver to the
boot process, you'll get a panic here because there's no controlling
terminal...

This isn't necessary. I'd not use it at all.

: uprintf(bus alloc bad\n);
: }else{
: uprintf(allocated bus resources\n);
: }
:

: }
Chances are good this is failing because there's another device
already servicing the device that has this range. This may mean that
you will have to have your driver loaded at boot time so it doesn't do
that and you may also have to hack sio to return an indefinite probe
(some non-0 negative number).
There's something called the softc. You should store store the
resource in the softc for the driver, not in a global.
: static int ser_isa_detach(device_t dev)
: {
: /* give back i/o region */
: if(rp){
: if(bus_release_resource(dev, SYS_RES_IOPORT, 0, rp) == 0)
: uprintf(releasd resources\n);
: else
: uprintf(error releasein\n);
: }
:
: uprintf(detached\n);
: return 0;
: }
Apart from the uprintf and sotfc comments above, there's nothign
really wrong here.

Hi,
I'm currently working on enhancements to ps w/ Garance A Drosehn.
I've just added some thread related stuffs and to see them, I'm
using the following program :
#define _REENTRANT
#include pthread.h
#define NUM_THREADS 5
#define SLEEP_TIME 10
void *sleeping(void *);
pthread_t tid[NUM_THREADS];
int
main(int argc, char *argv[])
{
int i;
for (i = 0; i NUM_THREADS; i++)
pthread_create(tid[i], NULL, sleeping, (void *)SLEEP_TIME);
for (i = 0; i NUM_THREADS; i++)
pthread_join(tid[i], NULL);
printf(main() reporting that all %d threads have terminated\n, i);
return (0);
}
void *
sleeping(void *arg)
{
int sleep_time = (int)arg;
printf(thread %d sleeping %d seconds ...\n, thr_self(), sleep_time);
sleep(sleep_time);
printf(\nthread %d awakening\n, thr_self());
return (NULL);
}
then, I compile this one in 2 way :

# cc -pthread -o pthread thread.c

Re: -lthr vs. -pthread
libpthread default is M:N threading model, kernel thread
entity is allocated on demand, things like sleep() only block
thread in userland, no kernel thread will be allocated, so
in your example, you won't see 5 kernel threads, only two
threads are showed here, the extra thread is a signal thread,
there is only one signal thread in process live cycle.
libthr is 1:1, when you allocate a thread in userland, it creates
a kernel thread too.
