You would do well to ignore any ISP-offered server.  Fedora has the most
up to date stable bind/named offered and bind will be kept up to date
via yum.  That is far more than any ISP nameserver I've seem.  Most are
literally a decade out of date, mangle any newer record types, and in
the case of morally corrupt ISP's, may even perform a man-in-the-middle
attack on the DNS data.  Just ingnore their servers.  You'll be happy

disk moves from /dev/sdd to /dev/sde

2009-12-16 Thread Wolfgang S. Rupprecht

I'm seeing something strange where a disk appears to change from
/dev/sdd to /dev/sde under f12.  I have a motherboard (Asus M3A78T) that
appears to have multiple onboard disk controllers.  When I boot with no
external storage plugged into the USB, my hard disks are assigned sda,
sdb, sdc sdd.  When I boot with, say, a flash drive, camera or cell
phone attached the external device gets the sdd name and my last disk
gets the name sde.  Now, that in itself doesn't cause any problems
because I don't have the disk sdX names wired into anything.

What is a problem is that after booting, something unknown (perhaps an
ATA reset?) causes the disk letters to be re-assigned just as if it was
at boot time.  If I have some flash-like external storage plugged in my
last disk gets shifted to /dev/sde.  At that point programs like
smartmon that are looking at the disk under the old name fail to find it
and generate an error.  smartmon -a /dev/sde does show the disk under
it's new name, but even the kernel appears to look for the disk under
its old name.  I see lots of the following mailed to me by chron: 

  /etc/cron.hourly/zzzdo-backup:

/dev/dm-0: read failed after 0 of 4096 at 0: Input/output error
/dev/dm-0: read failed after 0 of 4096 at 0: Input/output error

How do I nail down the disk numbering a bit tighter so that things don't
move around after boot-time?

2009-12-16 Thread Wolfgang S. Rupprecht

Rick Stevens ri...@nerd.com writes:
 The only way to ensure you're talking to the same drive is to use its
 UUID.  Most filesystems and devices on Fedora now have UUIDs associated
 with them and most of the necessary utilities support it.  For example,
 your /etc/fstab can specify a device either via device name (/dev/sda1),
 label (LABEL=somelabel) or UUID (UUID=weird-hex-string).

Thanks.  I (at the /etc/fstab level) do use a label that goes with the
drive, mainly the lvm VG and LV names.  The problem is that the lvm
mapper *internally* must still use the name that the drive had when the
computer first booted.  It gets confused when the drive gets renamed at
runtime (long after boot).

 I sure wish there was a standard on the order in which things get
 scanned.  Even network NICs vary.  On Dell 1850s and 1950s, the PCI bus
 was scanned for NICs before the on-board stuff, so any PCI NICs got the
 first ethX numbers.  The bigger 2850/2950 machines scanned the
 on-boards first.  GR!  It's enough to drive one absolutely mad at
 times.

Ditto.  I have my machine dual ported and I'd really like eth0 to be the
internal ethernet and eth1 to be the external.  (Some programs like
multicast progs seem to default to the first ethernet and it would be
nice for me not to spew packets towards the public internet.)

 I have the same problem for a couple of month (don't remember exactly
 how long it is) on my F11 (32 bit). I've asked it already on this list
 but had no response.
 I had similar problems in the past (with sudo / not su), and the reason
 was an error in the network controls (I tried to change the hostname by
 editing /etc/sysconfig/network, but forgot all other places to edit).
 This kind of delays are often DNS timeouts.
 If the network configuration is wrong, trivial things like printing
 last unsuccessfull login on 02-12-2009 from abcd.example.com
 take 15-30-60 seconds.

Hmm.  No 6 hours after posting this, the problem cleared up.  I'm temped
to finger the selinux-targeted-policy that I installed from
updates-testing for clearing things up.  That was the only change in the
intervening time.

As to the DNS issue.  Bingo.  /etc/resolv.conf to be exact still had an
old IPv6 address in it.  Oops.  I thought that the resolver should
failover and stay locked to the best dns server fast than 30 seconds.  I
see I'm going to have to figure out why it took so long.  Thanks for
reminding me to double check.

 With respect, that is nonsense.

I was just trying to say that the installation dialog makes it too easy
and therefore encourages people to change the defaults when in fact they
would be better off leaving things alone.

Sure you can run without lvm.  Sure you can put home on a different
partition.  Sure you can add other repositories during installation.
The problem with doing all that is it takes you off the well-trodden

f12 eclipse and adroid ADT errors

2009-12-02 Thread Wolfgang S. Rupprecht

I tried to install the f12 eclipse and use it with the android ADT via
the instructions at http://developer.android.com/sdk/eclipse-adt.html .
When I followed the Eclipse 3.5 instructions it bombed after the add
https://dl-ssl.google.com/android/eclipse/; step with the following
error:

Cannot complete the install because one or more required items could not be 
found.
  Software being installed: Android Development Tools 0.9.4.v200910220141-17704 
(com.android.ide.eclipse.adt.feature.group 0.9.4.v200910220141-17704)
  Missing requirement: Android Development Tools 0.9.4.v200910220141-17704 
(com.android.ide.eclipse.adt.feature.group 0.9.4.v200910220141-17704) requires 
'org.eclipse.gef 0.0.0' but it could not be found

This is totally incrutable to me.  What is it trying to tell me it wants
loaded and from where?  Is the fact that this is missing from f12
eclipse but installed in the oficial eclipse distribution from
http://www.eclipse.org/downloads/ a bugzilla bug?

 As the subject says, he's trying to change the background for the GDM

 Using gconftool-2 is generally the best way to achieve this, and works
 fine for me on F-12 (as it has in past releases).  Why it's not
 working for Fred remains to be seen.

You can also set it as a user's background via the normal preferences

 Actually WPA2 with 802.1X authentication is REALLY tight.  No MITM
 will crack EAP TLS (EAP TLS is a little different than the TLS used in
 the most recent attack).  Then use AES CCMP (not TKIP).

And there we have the real way in protecting a wifi access point: turn
off WEP, WPA (v1), and TKIP (under WPA2).  Leave only WPA2 and CCMP.
Then let the computer choose a 64-bit hex number for the shared key.

Too bad the good advice is always drowned out by the hordes that claim
hiding SID's and changing port number on ssh are the way to get
security.  (For ssh turn off everything but RSA and DSA -- this way the
computer chooses a strong password (really a secret key) for you.)

 Of course your management frames are not protected.  That is 802.11w
 that will soon be in products

 BTW, I worked on the 802.11 standards.  I use past tense, as in June
 my management had me move over to work on 802.15 standards. (I was in
 Atlanta last week for the 802 meeting).

Thank you for speaking up!  Will the new protocols require any HW
support or are they drop-in replacements on current wifi nodes?  Will
all the packets now be cryptographically protected?

Are the other dns config files ok?  The stock BIND config in f12 should

Re: spoof rsa fingerprint

2009-11-17 Thread Wolfgang S. Rupprecht

 In the scenario that the OP hypothesized, yes, spoofing the
 fingerprint would help the attacker.  A user who attempted to ssh to
 the router would not be warned that the host had changed and would
 submit their password to a rogue host.

 In answer to the original question, though, spoofing the fingerprint
 would be extraordinarily difficult.

I don't see any fingerprints stored in /etc/ssh/ssh_known_hosts or the
user's equivalent ~/.ssh/known_hosts, these are the actual public half
of the RSA keys.  Spoofing these means breaking RSA and generating the
corresponding private pair.  If someone could do this, I doubt they
would waste their talents on logging in to some poor schmuck's Fedora
box.  There are much jucier and lucrative targets.

 genhomedircon goes through the passwd file looking at the home
 directories for all the users.  So if a user has /home2 listed it should
 generate the file_contexts.homedirs properly with both prefixes.

 /home2 itself would need to be labeled with home_root_t just like /home
 is.  Dan's fcontext --equiv would work for this (set /home2 equal to
 /home) or it could be added manually using semanage fcontext.

Thanks Eamon and Dan!  

I do see that something magically added the /home2 versions since the
last time I looked.  It is good to know how to do this by hand to speed
up the process.

I don't trust myself to get all that math right (and guessing about the
underlying remapping).  

What I do is just copy the data to a good disk and then write zeros over

sectors that haven't been reallocated yet) and turn them into
Reallocated_Sector_Ct sectors.

I'm getting a lot of experience doing this.  For some reason my current

sectors.  I guess the Seagate perpendicular recording disks weren't
quite ready for prime time.  Almost -- but not quite.

The fastest way I found to zero the disk is to use the security erase
feature.  A disk that takes 4 hours to be zeroed with dd can be zeroed
in 2 hours with the built-in security erase.  It took me a while to
figure out how to get the security erase hooks to do anything but give
me the IO ERROR errno.  This seems to be the simplest way to get an
erase to take place.  (Suggestions and simplifications welcome!)

 sda2 cuz it simply will not allow more than 199 megs for the boot partition.
 That problem is about to end with the end of F10.

Why not just go with the flow and tell anacondia to use the whole disk
and be done with it?  It will redo the partition table, install a new
low-level boot loader in the mbr and make a new and shiny fs and/or lvm
and fs on each fdisk partition.  That is going to be the best tested
code path and unless you really want to help debug anacondia, why ask
for all that aggravation?

Did you see this in a freshly made user account or did you reinstall

I'd guess some dot-file is screwed up (.bashrc, .bash_profile, .profile,

You probably have a keyring that you didn't request courtesy of the

At one point, many fedora releases ago, there was some weirdness where
default.keyring and login.keyring interacted badly and that would cause
such a popup.  These keyrings seem as well documented as the rest of

Very true.  One has to ask why bother having a checksum at all???  Why
not just digitally sign the iso directly (with a detached signature).

Digital signatures are just hash-digests of the object which have been
individually signed.  

Signing the iso's directly (instead of signing a checksum file) solves
two problems: 1) one knows that the checksum hasn't been tampered with
and 2) the mechanics of which checksum command to use is hidden from the
user.  There is also another slight advantage, newbies don't end up
comparing the checksums by hand if they don't notice the -c flag to

Linux viruses (was Re: Windows vs Linux)

2009-06-09 Thread Wolfgang S. Rupprecht

 There aren't really any viruses in the wild for GNU/Linux, so it's indeed
 fairly unlikely to get one. The common viruses all target M$ Window$.

Just to be a bit contrary, there is at least one virus type, but it
requires the system admin to be foolish.  Look at the log files for ssh.
All those automated break-in attempts originate from linux, bsd (and
other unix-like) systems that have been compromised.  eg.

Jun  8 10:11:18 arbol sshd[23856]: Invalid user river from 194.165.4.142
Jun  8 10:11:18 arbol sshd[23857]: input_userauth_request: invalid user 
river
Jun  8 10:11:18 arbol sshd[23857]: Received disconnect from 194.165.4.142: 
11: Bye Bye

The vulnerability is a combination of bad defaults for sshd_config where
unix passwords are allowed for ssh logins and foolish admins and/or
users that choose passwords that aren't random letters or numbers.
Since users can't be counted on to choose good passwords, it is probably
best to have the computer choose a 1k random password for you in the
form of an rsa key.

Is it possible to get the fedora defaults for sshd_config changed and
help prevent newbies from making silly mistakes and giving linux a worse
grade with respect to viruses?

Alternately you can just put the current NAS address in /etc/hosts and

Re: Fedora 11 (Rawhide) and Firefox

Well, firefox has never been on my 10 best working programs list, but
Fedora/3.5-0.20.beta4.fc11 works for me.

The one annoying bug I see is that it no longer displays the full
google lattitude widget in iGoogle.  Something changed for the worse
and the friends list no longer loads.  Since that whole thing is a mess
of javascript, it isn't clear who's fault the breakage is.  It might
just be bad code on Google's part.

 Any thoughts and ideas?

You may just need to blow away your ~/.mozilla directory and start off
afresh.  You might also want to resist installing any add-ons and see if
things are a bit more stable then.

It if is still bad I'd run the memory test memtest86+ for a few hours.

 Truth is that there is a lot of computers which cannot act as a server

The scurge that is NAT won't get fixed until users start demanding real
IP addresses for their computers from their ISP's.  So far programs like
skype steal bandwidth from unsuspecting users with real IP's in order to
service the slackers behind NAT boxes.  That has to stop.

Now, SIP and especially RTP are good examples of protocols designed by
committee.  I'm talking large headers and a zillion different operating
sub-modes, many of them incompatible or at least ambiguous as to what
they mean in combination with one another.  Look at any ChangesLog for a
sip phone or open source program and you'll see all the weird cases the
software folks had to deal with.  That is never good.  It keeps the cost
of entry high enough that you won't see many folks try to write clients.

It would be good for some open-source group to just get back to basics.
Sending a stream of audio bits across the net shouldn't take a zillion
pages of code or a huge header for each data packet.

 that firmware is not accessed.

 I didn't pull that filename out of the sir, I looked to see what

 I have a related question. If I set up a tunnel to forward IPv6 thru

 any reason, I can use my secondary instead? I'd like to set up some
 servers on VMs in my DMZ[1] for testing.

In order to avoid the mess crated in IPv4 with lots of hard to route
direct assignments, IPv6 addresses are not handed out to end users.
They are only handed out to ISP's (in hunks of /32 if I recall
correctly), who in tun hand out /48's to end users.  That keeps the
routing table nice and small, but also means that if you are an end
user, you will have to play short-TTL dns games if you want a fail-over

 it could make a good standard firewall (?FIXME) - if anyone puts any

This is what f11 does:

 HTTPS with an unknown self-signed cert is barely any more secure than

It is a shame that there isn't a simple documented way to add other CA's
to Firefox's approved list or some system global way to add CA's for all
programs looking for pki certs.

I for one don't really trust external CA's for access to my computers
since I don't know their verification policy.  For all I know one of
them can be tricked into handing out a *.wsrcc.com certificate.  I feel
much more secure knowing that anyone signing with my CA first has to get
hold of the signing key and then decrypt it.

As for the man-in-the-middle attack, I'd imagine the biggest usage case
is an eavesdropped-in-the-middle and not someone that was able to break
the data stream and insert themselves.  Having an encrypted channel with
a slightly nebulous endpoint is still better than having an unencrypted

McVeigh used ANFO, a common and cheap high explosive used for road work,

That would make it a high explosive.

If your firewall allows such mapping and you have a global ipv6 address

In general, I think you'll want to make sure you run
system-config-firewall on all your machines and only allow a minimum of
services that you *really* trust on your IPv6 connected clients.  My
machines tend to only allow incoming ssh and nothing else unless the
data stream is opened from the client side.

 Or are there private addresses what the router gives to my pc.: eg.: with
 ipv4 a router could give 192.168.1.10... and that IP couldn't be
 pinged/nmapped from outside (More Secure???)
 Because I heard that there will be no NAT with IPv6?

NAT isn't needed if all you want is firewalling.  If you stick to
operating systems that supply usable built-in firewalls you'll be ok.

heat the little wire to flash-steam the ink etc.  Do it for too long and
you damage the wire.  On the mickysoft driver, this is all buried in a
binary blob and while folks could in theory binary edit it, they won't
for the most part.  In the OSS world, if they released sources, that
almost certainly wouldn't be as true.  This puts Lexmark in a very bad
position.  If they open it up they would need to figure out a way to
tell if a modified driver caused damage and not cover that damage under
warranty repairs.

Now there might be other issues too like BS patents, where everyone and
their brother has patents on all the obvious ideas surrounding printing.
Exposing the software when you know that the competitor is claiming
patents on half a dozen things you are doing isn't going to make the
legal dept very happy.

 That's also Debian's policy. But I don't think we need such a policy in
 Fedora. It wouldn't even fix this problem as we're not talking about
 command-line options here, but about GUI features.

I think you are reading it much to literally.

Good documentation is lacking, people are complaining and we have people
saying that I don't think we need such a policy in Fedora.  Amazing.

 If you want to help, you don't really need policy. Do you want to help?

In the last few years I haven't written much OSS, but you can be sure
that when I do, I do dig out my troff notes and cobble together a man
page for it.  I do practice what I preach.

Am I going to write man pages for other folks?  Nope.  Sorry.  First and
foremost I'm a strong believer in making the developer explain how to
use their program.  Doing so forces them to rethink the issues, makes
them wonder if something is done logically enough, maybe even gets them
to think like a user and wonder what they would find annoying with how
the program currently works.

 The policy you're proposing (and incidentally, also the Debian policy) is
 that literal. Requiring good documentation makes sense (though it's hard to
 define good documentation). Requiring it to be in manpage format and to
 document the command-line options (and not requiring anything else), even
 for GUI apps, doesn't.

If the problem is that troff is too arcane (and I'll be the first to
admit it -- I hate it) then that needs fixing.  I don't think it would
matter that much what the source for the manpage looked like as long as
man someprogram would dig up the documentation and display it in a
similar looking format.

The problem currently is some of the docs are accessible by man(1), some
by info(1) and others by grovelling around /usr/share/doc/ .  Instead of
the computer doing the work and finding the documentation and displaying
it, the user must.  Old hacks might know all the places to look, but
newbies sure wouldn't.

 How useful is a manpage like this?
 http://manpages.unixforum.co.uk/man-pages/linux/suse-linux-10.1/1/kalzium-man-page.html

;-)

That is a good example of a contentless man page.  I assume it was
written by some 3rd party that didn't really understand what the program
did, how it was meant to be used etc.

 You honestly think the bad guys wouldn't just sniff the wire, disassemble
 the driver and write printer exploding worms given the chance.

I didn't get the impression that they were as worried about their
printers being targeted by worms as much as they were worried that they
would be left holding the bag doing free warranty repairs on printers
that were broken by buggy 3rd party drivers.

As controllers become cheaper, hopefully the excuse of being able to
break the hardware will go away.

 I don't doubt that the printer control is done from the PC end, but I'd
 be suprised if Lexmark were dumb enough to just trust the PC commands.
 You don't DRM your toner cartridges and then act careless on the rest
 surely. I'd have thought they'd have DRM on the driver interface too !

The toner cartridge has lots more mark-up.  You can afford to put more
smarts in that than the printer. ;-)

In case it wasn't obvious, I'm not the slightest bit happy about
companies not releasing programming information either.  I just don't
think that MS co-marketing dollars is the answer all of the time.
Sometimes it is just laziness and a false sense of security through
obscurity.

 It was written by the Debian maintainer to fulfill a policy exactly like the
 one you were proposing. Do you see now why having such a policy at distro
 level makes no sense?

I never said that one should make some 3rd party write a placeholder
manpage.

One should waterboard the developer till he/she agrees to write the
manpage.

Re: Can't boot after an update

DB freddog...@yahoo.co.uk writes:
 I'm now trying to find a script that will clean /tmp automatically on
 a regular basis. (I think part of the backlog is due to the switch
 from Gnome to KDE)

I clean my /tmp on each orderly shutdown.  That way if the system
crashes, my /tmp is preserved but when I do a reboot, it gets cleaned.
Put this in /sbin/halt.local.

/sbin/halt.local:

#!/bin/sh
# wsrcc halt script

echo WSRCC: Clearing /tmp

cd /
/bin/rm -rf /tmp/* /tmp/.??*
sync; sync; sync;

#
# end
#

I used to use an age based clearing method, but that tended to remove
things I was still using if the system stayed up too long and it didn't
clear things quickly enough such as cases where something significant
changed and caused a name clash in /tmp.  (Try changing UID's around
sometime and forget about the files in /tmp.  Things won't be sane until
all those files get nuked.)

Re: F9 - F11 with only 1 partition

 I'm running 32-bit F9 with only 1 partition.. The lack of a separate
 boot partition prevented me from completing the preupgrade to F10. Can I
 upgrade to F11 or should I reformat and create 2 partitions before
 installing F11 from scratch? If I install from scratch I could switch to
 64-bit which would be nice. I would prefer to install/upgrade from DVD.

Unless you are testing things and really want to find all the
incremental upgrade bugs lurking in the corners, why not just let the
install DVD do a clean install from scratch?  Backup anything you care
about and tell the install DVD to use whole disk and let it go hog
wild.

You can use usb thumb drives too.  The fedora install doc should list a
few ways of doing that.  I recall using it to install F-10 on a dvd-less
netbook computer ~6 months ago.  I haven't tested this on f11 yet, but
here is the updated doc:
