Can you elaborate?  I've never looked at the actual iptable rules
generated by Shorewall, but why bother?  The configuration files are
perfectly clear and rational, and I understand exactly what I have
there.

It may not be the most appropriate list for his question, but it's not
nearly as narrow as you define it.  This list is much bigger than "users
and developers of the Debian Live scripts":

From:  http://lists.debian.org/debian-user/

Help and discussion among users of Debian
Support for Debian users who speak English. (High-volume mailing list.)


The above description makes it pretty clear this list is for _ALL_
Debian users.  Believe me, if there was a "non-gui headless server

so here I am. ;)

The Lenny package sets this up automagically during aptitude
installation, including setting the list of stratum 2 servers:

/etc/ntp.conf

..
# pool.ntp.org maps to about 1000 low-stratum NTP servers.  Your server will
# pick a different set every time it starts up.  Please consider joining the
# pool: 
server 0.debian.pool.ntp.org iburst dynamic
server 1.debian.pool.ntp.org iburst dynamic
server 2.debian.pool.ntp.org iburst dynamic
server 3.debian.pool.ntp.org iburst dynamic
..

First, something to consider, is that if ntpd is actually running,
ntpdate won't execute but will return an error, such as:

27 Oct 23:27:05 ntpdate[3775]: the NTP socket is in use, exiting

If you don't get the above error when running ntpdate, then your ntp
daemon is _NOT_ actually running.  This is likely why your clock is
drifting, because ntpd isn't running.  Make sense?  Check with top or ps
and make sure ntpd is actually running, and check your syslog et al for
errors, in case ntpd is running but not keeping time correctly.

Again, aptitude install ntp is fully automatic and shouldn't require any
manual configuration.  You may want to remove the package and reinstall it.

Voyage gives you a nifty script to install it on compact flash, with
appropriate targets for specific hardware, e.g., alix, standard pc, soekris.
The alix target has all the appropriate hardware support, i.e., geode cpu,
support to control the LED's, etc.

I don't think iptables is really your answer, by itself. What you're
really trying to do most likely requires you to set up an authenticating
proxy server on a separate bastion host. Still, if you want to do your
blocking on a single host, a little Googling around might yield some
useful results. For example, two seconds of searching found:


http://www.cyberciti.biz/tips/block-outgoing-network-access-for-a-single-user-from-my-server-using-iptables.html

I haven't explored the matter much further, but if the post is right, it
certainly looks like your best bet would be to whitelist only the users
you want to have TCP/IP access, and add a general DROP rule for everyone
else.

It certainly breaks the FHS, as well as being a potential security
issue under some circumstances . But webalizer certainly supports
running from pretty much any random conf file with the -c flag.

In addition, the webalizer cron script supports running *multiple*
instances of webalizer by processing each of the *.conf files in
WEBALIZER_CONFDIR (by default, /etc/webalizer). You could try moving the
weirdly-placed webalizer.conf file there as, for example,
"the_other_admin_was_a_goober.conf" and let the nightly cron job run it.

You probably want to drop the executable flag, except on directories.

Did you try mimeopen?  It seems to coincide with what pcmanfm does.  The -d 
option lets you select a default; that should change the default for pcmanfm 
also.

Yeah, sure. But Voyage is basically Debian designed to run in RAM, this way
you don't keep writing to the compact flash card. You can apt-get
anything. 

I guess you could also boot regular Debian off of a USB disk. The
bigger boards also have a 44 pin IDE connector. Maybe use a 
2.5" laptop drive??

dpkg fails - exact errors

[Daniel Dalton]

Hi,

I've tried to remove adobe-flashplugin, with the force option, but that didn't 
work, now if I take dpkg's advice and reinstall I also get errors.

Here is the errors I get with the removal:

dpkg: warning: overriding problem because --force enabled:
 Package is in a very bad inconsistent state - you should
 reinstall it before attempting a removal.
(Reading database ... 268294 files and directories currently installed.)

Now here is what I get with the install of adobe-flashplugin using dpkg -i 


Selecting previously deselected package adobe-flashplugin.

dpkg: error while cleaning up:

So if anyone could tell me how to totally remove this package, so I don't get
anymore errors, and so I can continue using apt to install other packages, and 
updates, I would greatly appreciate it.

Thanks,
Dan.

Well, I don't see mention of it in dnsmasq(8), and not much via Google either,

A little too hasty in my previous response to you. I think you're talking
about how to install them rather then where to get them? The newer developer
releases use *.crx files. Chrome should recognize them as such and offer to
install them for you. Is that not working for you?

I don't think so.  Using 100% CPU when the application demands it
isn't a bug, it's a feature.

This is also the wrong list; it's for users and developers of the

[Todd A. Jacobs]

I am currently having a problem with my X server displaying the cursor
as shaded black, which is rather hard to see. This happens as soon as
the gdm chooser is up, so I don't think it's a KDE4 issue.

Is there a setting in xorg.conf or elsewhere that will give me the

Re: Local DoS in kernel 2.6.26

[David Cottrill NCH Software]

It may chew up an old computer but a new one won't really do more than 
sniffle.


It goes on an endless loop sending short messages to itself which aren't 
very long. If you wanted to kill a modern computer with that script 
you'd have to set ma=some large number.


It can't kill off a modern multiprocessor CPUs because it is a single 
process, you'd need a forkbomb to do that.
It can't fill RAM because modern computers use more than that program 
was made to absorb.


To kill off a computer quickly:
step one: ":(){ :|:& };:"
step two: reboot because your machine has stopped responding

You could consider a similarly priced hardware alternative. You ever 
hear of the PC Engines Alix boards? Link: http://www.pcengines.ch/alix.htm

They come in a variety of configurations. Generally, you get x86 Geode CPU,
1 to 3 ethernet ports, more than 1 USb port, mini-PCI slots, 256MB RAM, a DC
jack that supports anywhere from 7v to 20v DC, serial ports, and the ability
to run Coreboot (formerly LinuxBIOS). 

You could could Voyage Linux directly from a compact flash. Link:
http://linux.voyage.hk/ It's basically Debian for x86 embedded devices. It
keeps apt and runs the entire OS is RAM.

The Alix 3d2 board is available for about $100 USD.

Tanks for the ideas, I'm still stuck

I've reinstalled everything with mime* or gtk* in the package name
(aptitude reinstall ) and am still having trouble "launching"
file
types. I also logged on as user root to see if it was my profile but root
has the same symptoms. So I created a new user and verified it with them
too.

In pcmanfm the "type" is listed as "executable" when the file is chmod
700. When the file is double clicked the wait-watch is displayed briefly
and nothing happens. If the file is chmod 600, pcmanfm brings up the
"Choose an Application" dialog. Does anyone know how this list is
populated? 

In pcmanfm there's also the option to right click on a file and "open
with..." and when I check the box to always open, for example MP3, with
Audacious2, it does not retain the association. Doing this a couple times
shows Audacious2 in the menu more than once. I cannot find where these
lists are stored and have grepped recursively through $HOME (grep -r -i
audacious *) with no results.

Any other suggestions are greatly appreciated!

You might also want to hit up TLDP.org and you local manpages.  Iptables is 
somewhat complex, but it is probably also one of the best documented sections 
of Linux administration.

I can't help you with guarddog.  I write my iptables rules by hand so they 
remain understandable.  I can't stand the trash that most iptables rules 
generators produce.  (Shorewall, I'm looking at you.)

You are probably right - I am complicating things for no good reason.

Just as an aside, there seems to be a varierty of usb to ethernet 
connectors, at a variety of different prices.  Some seem to be so cheep 
that they can be little more than a usb connector and rj45 connector.  
Do they all work with standard debian?

The suggestion was made to use iptables, gui-owner --> drop.

Iptables is "configured" at boot time, but this is not where it gets set up.
I use the kde3 program guarddog. Its rule set gets set into iptables on ifup. 
I would need to add a rule there as well.

Listing the rules yields a long, marginally comprehensible mess,

Question would be: What rule to add? How it relates to all the others. I do 
not really understand much of iptables.

I don't know if dnsmasq can, but there is support for dhcp forwarding in the 
dhcp specification, and dhcpd can be configured as a forwarder.  FWIW, I would 
think dnsmasq could be set up as a forwarder as well.

So, is it possible in any way (preferably simple) for systemB to send a dhcp 
request and get a response from the AP?  I have dnsmasq running on systemA, so 
I can set it up to do something.  Do I need a "dhcp forwarder" of some sort?

If you check the box, the "Apply" button should change its icon and have a
keyring on it. Then pressing Apply should pop up an authentication dialog,
asking you for the root password. Do you get such a dialog?

For further discussion, I guess we should take this off list.

I'm running the same version; What extensions are you having the problem

dnsmasq problem: nokia cell phone does not accept dhcp offer

[H.S.]

Hello,

I am trying to connect a nokia cell phone to my home wifi network. The
same phone has reportedly worked properly on another home wifi network
which has a Belkin wireless router. The phone is set to acquire an IP
address automatically, i.e. via dhcp.

BTW, my home wifi network is provided by a wireless card in a machine
running Debian Testing and 2.6.26-2-686 kernel.

The wireless is network provided by hostapd using madwifi driver.
Windows and Mac machines work properly with this wifi network (at least
no big problems noted, certainly not in Windows clients).

When I try to get the Nokia phone to connect to the wifi network, I get
these lines in my dnsmasq log (to see lines without wrapping, here is
the pastebin link for convenience - http://pastebin.com/m466c8fd2):

Anybody know the problem might be?

If I switch off dnsmasq dhcp queries logging, all I see are two lines of
DHCPDISCOVER(ath0) and DHCPOFFER(ath0) repeatedly in the log with no
acceptance by the cell phone.

It appears as though the phone is not accepting the dhcp offer.

However, if I give the phone a static IP address in its configuration,
it works properly on the wifi network. So it appears as though the
problem is dhcp related.

Hints? Suggestions?

Installed stuff:
$> dpkg -l *dnsmasq* hostap* | grep ^i
ii  dnsmasq   2.50-1  A small caching DNS proxy and DHCP/TFTP server
ii  dnsmasq-base  2.50-1  A small caching DNS proxy and DHCP/TFTP server

As already said, setting gdm to autologin will of course not work. you actually
have to type your password once.
If you are using autologin, you might just as well use a blank password for your
gnome-keyring (not that i recommend that).

Bridging (i.e. brctl and friends) can only be used to connect two networks 
that use the same layer 2 protocol.  Ethernet and 802.11a/b/g do not use the 
same layer 2 protocol.  I believe at the very least you'll need to use an "ARP 
Proxy", and you may be better off just routing traffic.

I *think* we have the reverse working: [laptops] <-> wlan0 [OpenWRT AP] eth0 
<-> [AT&T Router], but I didn't set that up, so we might be having the AP run 
a dhcp daemon and route traffic.

There was a time when I played with something similar, I used tcpdump
(even on bridged interfaces) to see where the packets disappear.

As I remember I needed

echo 1 > /proc/sys/net/ipv4/ip_forward

on [SystemA]. I also used packet filtering, so I needed the rule:

$IPTABLES -A FORWARD -i br0 -o br0 -j ACCEPT

I tried that just after the upgrade, and the symptoms where the same with
the pre-upgrade kernel version at the time, so I suspect it's not really a
kernel problem ... plus the dmeg's correctly recognize a HID device, as the
dmesg attatched to my first mail shows ... I suspect bug in udev rules or a

I think that is the answer, limit the switch to have the cable modem, 
plug computer and existing cable router on it.  the "lan" side of that 
cable router will be where I connect everything else and can use dhcp 
with confidence there.

I presume nfs (which I have not used before) will still work connecting 
the plug computer as an nfs client throught the router (which is a NAT 
device) to one of the backend servers running a large disk and the nfs 
server end if I port forward correctly. [one particular usage of my 
external web site is to provide access to some large files - I am happy 
for this to fail if I turn off my in home computing environment leaving 
only the plug computer running.

   The link I gave you is for the compiled version ( in a zip file )...
your links are for the source if you want to compile yourself. I wouldn't
recommend that.
I simply unzip the dl'ed file (it's about 21 megs) into my home directory -

build bridge with DHCP

[green]

Hey all, I need a bridge for the following scenario:

[systemB] eth0 <--> eth0 [systemA] wlan0 <--> wlan0 [AP]

I am working on systemA, which normally sends dhcp requests answered by the AP. 
 
I want to add systemB to that network.  When it sends dhcp requests over eth0, 
the AP should answer.

To accomplish this, I have tried:

-- /etc/network/interfaces
iface br0 inet dhcp
  bridge_ports eth0 wlan0
--

# ifconfig wlan0 up
# iwconfig wlan0 essid myap
# ifconfig eth0 up
# ifup br0

br0 sends a dhcp request which is answered by the AP.  Everything seems to work 
fine on systemA.  But systemB sends dhcp requests and is never answered.  They 
don't seem to be getting through systemA to the AP.

I have also tried, in /etc/network/interfaces file:
  bridge_stp off
  bridge_maxwait 0

and tried:
# brctl setfd br0 0

Any suggestions?  Thanks.

It works fine for me, on a mostly Lenny system, in a terminal, in openoffice, 
in iceweasel (soon to be replaced with uzbl)...

I have the following line in ~/.xsession file:
 xmodmap ~/.xmodmaprc

And in ~/.xmodmaprc (! is for comments as according to xmodmap(1)):
 ! Enable compose/deadkeys for special characters
 keycode 113 = Multi_key

And I found that keycode (for my right alt key) using xev(1).

ntpdate is a one-time operation. You fire it off, typically in
the boot process, and then you don't run it again. I suppose you
could put it in a cronjob.

ntp-server does continuous synchronization. That's what you
really want to be running.

No, it can work. You are just confused.

The switch does not know anything about IP addresses. It
understands ethernet MAC addresses. 

$ /sbin/ifconfig
eth0  Link encap:Ethernet  HWaddr 00:24:1d:28:73:b6  
  inet addr:10.1.4.55  Bcast:10.1.255.255 Mask:255.255.0.0
  inet6 addr: fe80::224:1dff:fe28:73b6/64 Scope:Link
  UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
  RX packets:12194355 errors:0 dropped:173155950949126

See that HWaddr: field?

That's a MAC address. It should be unique on every network
interface.

Routers are devices that make decisions on the IP level.
Switches make decisions on the ethernet level.

What you will have problems with is running DHCP, as you
mentioned. Here's what you do:

Get a USB-ethernet connector for your plug. Now you have two
ethernet ports. One goes to the cable modem, one goes to your
switch. Life is good.

Alternatively, hardcode IPs for everything on that switch. You
can either hardcode IPs for your wireless devices, or run DHCP
on a separate subnet  there.

Try

sudo modprobe md_mod

to load the MD driver, then check /proc/mdstat.

I have started time server, ran ntpdate command. The time matched.
Several weeks later the time is off by a little more than a minute.
What is controlling how often time server updated by the ntpdate

I don't have any such problem on my laptop (unstable), except when

problem with debian lenny 503 netinstall

[Morten Gulbrandsen]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Dear debian users,

again I tried with debian lenny 503 netinstall.

first problem was printing.

It issued something like  kerneloops.

I accepted so the message may be sendt to kerneloops.

I was able to print a cups test page.

On previous versions of debian,  I think  500
printing was not a problem.

The next problem I'm likely to face is when new updates are offered.

that chrashed my system.

I can try to send a succesfull install report. Also with the cups or
printing debug message.

I like this paper and try to follow the steps as suggested here:

http://www.debian.org/releases/stable/i386/

http://debian-community.org/lennyfaq/

http://www.doviak.net/debian/debian_install_guide.pdf

is a nice guide howto install Lenny.

This FAQ needs your questions and answers !

I can also try the older version of debian, which had everything right
on the fly.

debianlenny503 is difficult for me currently, and the
linux penguin noticed something strange about the kernel.

It still may be a user error.  Debian may have new features which
operates different than what I'm used to.

Question: is this known? How can I troubleshoot this?

except dmesg  lspci and the troubleshoot.txt ?




Sincerely yours,

Morten Gulbrandsen

you will see a gui at your end. ssh is supposed to take care of setting up

use a vnc server to show the remote desktop

setup x to accept remote connection and log in remotely (gdm/kdm etc support 
this)

Re: Network manager doesn't autoconnect to wireless networks in stable?

[chombee]

For me it happens every time I boot up the laptop -- it does not 
automatically connect to my wireless network. Apart from not 
automatically connecting network manager works perfectly, detects all 
the wireless networks, connects to my network when I click on it, so it 
feels more like a configuration issue than a driver one. I'm running 
Debian stable, when I was running testing recently on the same laptop it 
_was_ automatically re-connecting.

The laptop in question is an OLPC XO-1 running DebXO, a build of debian 
for the XO-1 with a custom kernel. I tried the ifconfig and iwconfig 
commands but I don't seem to have them installed. Not sure about 
installing wireless tools and whether they might mess with network 
manager.

Double check that you have identified what your wireless interface is in
 wicd's Preferences. By default I believe it is left blank. Also in
there, you may have "always show wired interface" selected.

Is your user a member of the 'netdev' group?  You also need to assure
that only the 'lo' interface stanza is uncommented.

Unfortunately my crystall ball is broken, so I'm unable to find out what
could be causing the problem. You'll have to resort to the old-fashioned
way of posting the output of the commands you try so that someone can
come up with a solution.

Hi,

I tried to install a deb package from a website, it only parcially
installed, and now won't remove. I've even tried using the --force
option, it just says I should try reinstalling, but when I do that I get
errors with installations. So how do I remove this package from my

thanks a lot for mentioning this hint, but I was talking about the

Any recommendations for that?

wicd fails to detect wifi networks

[Liviu Andronic]

Dear all
More wicd blues. Some time ago I reported that wicd was failing to
start the GUI [1]. After getting more and more dishearten with
NetworkManager, I gave wicd another try. This time the wicd GUI starts
all right, but it identifies a wired connection to which it tries to
connect (even though no wire is plugged to the laptop). Most
annoyingly, it does not find any wireless networks (as if the wifi
radio was killed, although it is well up). All this is on Debian
testing with wicd and dependencies up-to-date.

Any ideas on how to fix the issue? Thank you
Liviu

kernel panic when doing mkfs.ext3 on a /dev/md0 (/dev/sdb /dev/sdc)

[Leonardo Ruoso]

Hi,

I have a fresh Debian Lenny Box with three Sata Disks (250GB and 2 X 500GB).

"/" is mounted on the first disk (/dev/sda) outside any raid array.

The other disks (/dev/sdb and /dev/sdc) have only one raid partition
each and were used by mdadm to create a software raid array
(/dev/md0).

I keep getting Kernel Panic whenever I try mkfs.ext2(3|4): mkfs.ext2 /dev/md0.

I googled it, but most of the kernel panic pages refers to booting
from a raid array, which is not my case.

TIA,

Wondering about doing something strange with networking

[Alan Chandler]

I am contemplating the possibilities with the plug computer, as an 
always on, router/firewall/web server for my house.

Unfortunately, although I could potentially use the usb port as an 
additional networking interface, there is only one built in network 
interface.

Now, I know from the past that from a linux point of view that shouldn't 
matter, since I can easily have interface eth0 AND eth0:0 ...

However, when it gets to actually cabling the thing up, I am getting 
confused between physical paths and logical paths.

I'll try some simple ascii art to draw the proposed setup

 --  -
| Ethernet || Cable Modem |
| Switch   | -
|  | -
|  ||Plug Computer|
|  | -
|  | -
|  || WAP |
|  | -
|  | -
|  ||Linux Desktop|
 --  -

In essence we have a number of devices hanging off an ethernet switch
My ISP requires I have a dhclient request a lease, through the cable 
modem.  So I need a logical link from eth0 on the plug computer through 
to the cable modem

The remainder of the devices - although ideally should use dhcp, could 
be configured with static addresses (and therefore also routes) to 
regard eth0:0 on the plug computer as a gateway (the plug computer would 
use 192.168.0.1 as its eth0:0 interface IP address, the dhcp allocated 
address on eth0 would not be in that range).

I think, in this scenario, the switch would soon learn not to send arp 
messages saying who has 192.168.0.x address to the cable modem, 
(although I am not sure it would matter if it did).

What I am less certain about is how I can cater for Wireless clients 
coming in over the WAP, who do really need dhcp allocated addresses.  My 
guess is that they would be requesting leases via some broadcasting 
mechanism, and that there is no way for the ethernet switch to prevent 
them going to the cable modem (and thence to my isp) and the dhcp server 
at my isp responding.

Is what I am trying to consider impossible?

The default keyring should be automately unlocked if you are login by
typing your username and password in gdm, did you enabled auto-login
in gdm?

Re: Linux Raid Partitions

[Stephen Grant Brown]

Hi Dan,

Thank you for your reply.

/proc/mdstat -> no such file or dir
/dev/md0 -> no such file or dir

mdadm -Q /dev/sdb2:  -> device 0 in 2 undetected raid1

mdadm -Q /dev/sdb4 -> device 0 in 2 undetected raid1

mdadm -A /dev/md0 /dev/sdb2 /dev/sdb4

=>

mdadm: error opening /dev/md0

How do I create /dev/md0?

Thanks for your help and patience.

Yours Sincerely Stephen Grant Brown

Hi All,

How do I mount this partitions so that I can copy the files on this

You may or may not be able to do so.

Install mdadm (apt-get or aptitude) if you don't have it
already.

Plug in the drive.

Check /proc/mdstat to see if anything is being mounted. If so,
you have a /dev/mdX filesystem available to you now.

If not, you want to investigate the partitions:

mdadm -Q /dev/sdb1
(and the same for the other partitions)

Do you have all the partitions that were part of a RAID set? If
so, you can assemble them:

mdadm -A /dev/md0 /dev/sdb1 /dev/sdb2...
or something similar.

If you don't have needed partitions, you may not be able to get
anything. You may be able to reassemble a partial set of a RAID1
or RAID5 set.
