Maybe you *should* use GIMP, because it handles such cases in an extremely

You could just press Shift+Ctrl+V (create new file from clipboard) and you're

 Can shorewall be used with firewalld?

No, it shouldn't, since both eventually apply different iptables

 I'm surprised that I have never seen an article starting
 In Fedora 21 you will have to choose between firewalld and iptables.

Unless I have severely misunderstood the whole concept, firewalld
relies on iptables.

Btw: shorewall is great, have been using it a long time (with some
minor modifications). Just disable firewalld entirely and keep
shorewall, firewalld won't protect you anyway if not configured after
install. An iptables -L after a fresh F21 install shows no
protection.

 I know, I would end up with either broken or lost parts, or not be able

I have had two L*gitech Anywhere MX mice, and could fix both doing
exactly what is described in the link above. So I'm confident you'll
eventually manage it :-)

The whole procedure looks difficult and scary, but isn't. The
little switch (see the picture provided in the link) is what's
most tricky to get re-installed properly. I used a little piece of tape to
hold it in place while putting the cap back on again.

In the long run, I have had those two Anywhere MX and several M505 and
the like from L*gitech, and will never ever buy any L*gitech mouse
again. I also own(ed) a Micros*ft office mouse (the inexpensive one), an
Intellimouse from the same producer and some cheapo no-name mice, and
never encountered the double click problem with them, so maybe this
problem indeed is L*gitech only. There are a whole lot of reports of
it on the net..

 Not clear if this satisfies OSS requirements of Fedora but it would be at

The author of this package states:
It’s the first public and testable version, don’t expect it to be
stable and production ready.

So while this may be a beginning, it's most probably not production
ready.

Here's another program which has quite the functionality pdftk has. I
just downloaded the source and compiled it (it needs the ocaml
compiler and libs to be installed and some hackery in the makefiles):

Will give it a try since I heavily depend on pdftk functionality

XFCE on F21 desktop

2014-11-23 Thread Heinz Diehl
Hi,

up to F20, I used the respective 4 GB full DVD image to install
Fedora, which also contained the XFCE desktop. Now, with F21, there's
a desktop and a server edition, and it seems the full DVD is missing.

Does the desktop edition also contain the XFCE desktop, or do I have
to use any XFCE spin now to get XFCE? And where are all the
development packages and libs, are they still on both editions?

Thanks!

Thanks, Kevin. That was what I wanted to know.

 You can of course install Workstation, then 'yum groupinstall
 xfce-desktop'. 

Hmm, so I have to install without a desktop environment first, to add 
XFCE after installing F21? Installing GNOME just to finally swap it
for XFCE sounds weird.

 You can also use the Xfce spin images, which haven't gone anywhere. 

Ok.
 
 You could also get the network installer and choose Xfce when you
 install. 

This is not an option for me, my internet is not fast enough. In fact,
I can be happy to have at least reasonably useable internet at all
where I live. Thus, the big Fedora DVD was quite perfect in my case.

Just re-run yum update, this should do it. AFAIK, CTRL+C is nothing
else than a SIGHUP, so yum should have terminated

 Does it make any difference if mutt is compiled with '--with-gnutls'

When compiled with --with-ssl, it uses openssl for TLS,

(Btw: there is no --with-openssl configure option).
 
 Using the same .muttrc file I use in fedora the TLS connection
 'aborts' and I get the error message:
 SSL failed, I/O error. Could not negotiate TLS connection.

Is the certificate properly installed in /etc/pki/tls/certs?
Openssl looks in that place and aborts if the servers certificate
could not be validated. Gnutls offers you to accept it manually,
if the host name does not match.

(Disclaimer: I'm not using a Fedora mutt).

Yes, you're right, it should. Tried it some minutes ago.
Since I'm neither using a Fedora mutt nor a Fedora openssl, my setup

If the certificate is in place, maybe you could invoke openssl

 And then we might be talking about different things.
 These might be general certificates. When I connected to my
 ISP with mutt the first time and I had to accept a certificate
 I had the impression that a personal certificate was generated
 to identify ME to the server in the future. And this certificate
 was saved by mutt in a file ~/.mutt_certificates.

Nope. When you connect to your mailserver for the first time and its
certificate can not be validated (e.g. because there's a missing link
to /etc/pki/tls et al.), mutt asks you to either accept it once, for
alltime or to discard it. In case you choose to accept it for all
time, it get's stored in ~/.mutt-certs. From now on, mutt will accept
this certificate because *you* told it to do. This certificate carries
a signature of the ca-cert which has issued it, but mutt was unable to
verify it. Thus asking you to decide.

 The muttrc manpage also mentions the following config variables:
 'ssl_ca_certificates_file'  'ssl_client_cert'. But these also do
 not work with my Fedora '.mutt_certificates' file.

ssl_ca_certificates_file is meant to point to something like the
tls-ca-certificates.pem file. But it does only work when compiled with
--with-gnutls.

 I don't expect it will do any good to copy the general certificates
 to the Mac.

Are there any CA-certificates installed on the Mac which are available
to mutt? If not, it could be the cause of your problem.
 
 And then the situation is complicated by using Linux programs
 in OsX via the Homebrew setup. 

I have noe clue :-)

As far as I can see from the description, these are the unmodified

 Btw, maybe my bug reports did not address the correct component (kernel) but 
 they have not
 been assigned yet. (Should I file under irqbalance?)

No. Most probably, it's a kernel bug. It could be a bug somewhere else
which triggers this one. Historically, such bugs didn't occur when
irqbalance was disabled, but this does not automatically mean that
it's irqbalance itself which is buggy.

 http://ur1.ca/iawmi - http://paste.fedoraproject.org/139547/00617141

Reading your dmesg dump, I'm not convinced that the irq handler is
what causes you problems. Some years ago, the code was modified that
the missing interrupt was ACKed, thus letting the machine proceed. 

However, you have a seriously segfaulting browser (firefox?) which
corrupts the memory. The general protection fault could even be caused
by a null pointer dereference. I guess that's the problem.

In addition, are you at F22? Your dmesg says you're using a 
3.17.0-0.rc7.git2.1.fc22.x86_64 kernel. When compiling a kernel source
rpm meant for F22 on a F20 system, the package would be tagged fc20.

If you install a Fedora kernel: yes.

I think: if you're able to reproduce the error easily, you should try
to bisect the patch which introduced the faulty behaviour. This would
only make sense with a vanilla kernel.

The first step would be to find a kernel which isn't problematic, and
the first one which is. Here's how to do it:

In that case, you should download your kernels directly from
kernel.org. It's not a big deal to compile a kernel on your own. 

1. Download e.g. the latest mainline kernel from kernel.org
2. Unpack it into /usr/src
3. Copy the latest .config from your actual Fedora kernel (/boot) into
   the root of the kernel sourcetree
4. make oldconfig (maybe you have to configure some new options here)
5. make
6. make modules_install
7. make install
8. Reboot your new kernel

This kernel lives peacefully alongside your Fedora kernels, and you
can delete the respective files under /boot, the sourcetree and the
modules in /lib/modules/ if you want to remove it. You do not damage
your Fedora kernel installation or the like. It's safe.

If you want to bisect, the steps to compile the cloned kernel sources
are the same as above.

Btw: there hasn't been any update to -stable in nearly 2 weeks,
because the stable maintainer was too busy to push out a new release
during this period. However, 3.16.4-rc1 was released today and 
will soon be transferred into 3.16.4.

Btw2: didn't disabling irqbalance workaround the phenomenon?

No. Your kernel gets installed by make install. Grub.cfg
will also be updated. After make install, you're done and ready to
boot your new kernel. No need for further (grub) action.

 I see: makes sense! Btw, 3.16.4-rc1 is not available on www.kernel.org.

https://www.kernel.org/pub/linux/kernel/v3.x/stable-review/patch-3.16.4-rc1.xz

The patches for the stable review are not showed on the kernel.org
main page, they live in the stable-review subdirectory as shown
above.

 What is the difference between this and 3,17-rc7?

3.17 is the mainline kernel which is under actual development, and
will be the stable kernel once released and updated. Soon after 3.17
is released, the merge window opens, which is the time the developers
are sending new patches to Linus. After 3.18-rc1 is released, the
merge window closes, and usually only bug fixes are accepted then.
Important fixes will be backported to the stable kernel trees, thus the
different minor version number releases.

In short: the actual mainline kernel is the one which is most
up-to-date (3.17 will be released soon..).

 What I don't quite understand is that there seem to be no issues when
 the system is rebooted. But issues arise only upon a wakeup from
 hibernate. Which I did, as advised in the mailing list here, doing the
 following: 
[]

With grub2, an additional resume boot parameter is not needed, as 
long as your swap partition is properly formatted (mkswap, swapon) 
and referred to in fstab when installing your kernel.

If this gives you problems, you could try to disable irqbalance to

kind of a warning, if I remember the source correctly - there were
hard lockups some years ago, and AFAIR the code around the missing
interrupt for a certain cpu vector (take a look into irq.c) was
modified to ack the missing interrupt, giving the system a chance to
proceed. Feel free to correct me if I'm wrong.

Then, you should definitely report this to the Fedora kernel folks.

 How do I disable irqbalance?

You can do a yum remove irqbalance or a systemctl disable
irqbalance.service. And add acpi_irq_nobalance to the kernel boot
parameters in grub.conf.

 And there appears to be no irq.c on my system. 

It should be in the arch/x86/kernel/ directory of your kernel sourcetree.
It's been quite a while I tried to understand this area of the kernel.

 I did submit a bug report yesterday but it has not been assigned yet.
 Looks like an obscure issue. 

This (and/or similar bugs) are going on for a while. I remember
those hard lockups from quite a few years back in time (at least in
the 2.6 generation). Not sure if they have the same origin/cause,
though. If I remember this correctly, both a racy irq migration
code as well as a faulty BIOS were discussed.

Maybe there is a BIOS update for your machine?

Yes, you are right. I was imprecise. What I meant is that barely
increasing Tx power is not verly likely to help. Increasing it over
the limit does more harm than good, leading to unstable connections
and data loss.

The Tomato firmware wikibook says: 
Transmit Power: Sets the transmit power in milliwatts. High settings
may cause nonlinearity in the transmitter causing loss of data,
interference to other users and channels, and a high “noise floor”. It
may also overheat and shorten the life of the transmitter.

I have experienced that myself while experimenting with it. A subtle
increase did no harm, but was no improvement either. Increasing the Tx
power further lead to a big amount of retransmissions and decreased
speed.

   Bit Rate=72.2 Mb/s   Tx-Power=15 dBm

 So, reason I am asking is that I would like to increase Tx power to 30dBm
 due to poor connectivity with the hotspot router.

There are two barriers: 

1. the capability of your adapter
2. CRDA

For most countries, 2.4 GHz is limited to 15 dBm, so iwconfig won't
help. The only thing you can do is to check if your router has WMM
enabled for the 2.4 GHz band. If so, you have a chance that your
adapter can use HT/VHT (aka 802.11n/ac), which in turn allows a
slightly higher tx power (but quite sure not 30 dBm).

Btw: increased tx power also leads to increased noise. You should
consider other ways to improve the connectivity to your AP (miving it
closer, using a repeater...)

You're absolutely right. I'm perfectly clear that F21 is still under

 I am simply seeking thoughts on the basic approach, alternatives, other

When logging into your bank account (or the like) the very first time,
make a copy of its certificate/fingerprint. Every time you connect, 
verify the certificates fingerprint first. If it differs,
take contact with your bank to make sure that it was changed. Do not
enter anything. This procedure will make it impossible to phish or
MITM'ing your credentials.

Second: use a good password manager, e.g. keepassx or the like.

Unlike others in this thread, I would not recommend you to install all
these add-ons, but trying to keep your system as native as
possible. The more you add, the more you risk to be exploitable and to
encounter bugs.

check the fingerprint before entering any credentials. You can
clone-copy a website, but you can't fake the fingerprint of the
certificate. It's that easy, and thus not understandable to me why
there is ongoing discussion about phishing. Not that I think global
dissemination of how to check the certificates fingerprint would
eliminate it, but it would at least reduce it drastically.

 The security of personal banking is terrible, anyway.  e.g. Try phoning

You can't spoof a certificate, but create one on your own and

Therefore the fingerprint check. Once you have the fingerprint 
of the genuine certificate of the site you're communicating with, 
you can easliy detect any MITM, because it is not possible to 
produce two certificates with the same fingerprint (unless

One way to create a bootable USB-stick is to run isohybrid on the .iso

the stick. e.g.:

1. isohybrid sysresccd-image.iso

folks are advising against using the discard mount option, it depends
on what's important for you and how your system behaves. In short: you
have to try for yourself what fits your needs.

Btw: great that there's proof for at the discard mount option can
result in lower performance. But, as always, this doesn't take into
account if and to what degree this affects real life behaviour, which
also varies between the respective real life situations...

I guess the Fedora kernel .src.rpm compiles just fine doing a

problem.

 So I'll wait until a clever patch finds its way into the (Fedora-)kernel.
 Meanwhile I stick to the 3.14-kernel.

According to git, 3.14 has been released 30 mar 2014. The offending

It takes no time when you already have a complete kernel tree :-) 
You can just apply the patch, type make and your're

Otherwise, if you plan to recompile a few times more, setting up
ccache could be a good idea.

 But I finally succeeded in building and installing a (reversely) patched
 kernel package: kernel-3.15.6-200.fan.fc20.x86_64, with the hopefully

Well done!

Unfortunately, I have no nvidia graphics to test your work. But I'm

 Your expertise with kernel would be very welcome for the Fedora kernel also,
 when you offer Heinz. ;)

Here's what I'm doing (and what I basically have been doing in many years):

1. Download a kernel from kernel.org
2. Extract it into /usr/src
3. Apply some minor patches
4. Copy my .config into the kernel sourcetree (alternatively make
   config, make menuconfig or thelike - in this case, you can of
   course omit 5.)
5. make oldconfig
5. make -j4
5. make modules_install
6. make install
7. reboot

In short: a simple kernel compile/install. Your kernel will live 
peacefully alongside with your distribution kernel(s).

For those who just want to try: a good starting point for a customized
.config would be the .config of your distribution kernel (see /boot).
When I'm configuring a kernel for a new machine, I usually load and
connect my stuff and do a make localmodconfig and take this as a
starting point for further customizing, as I'm (more or less) familiar 
with what I need and where I must look for it in the .config.

Nope. Every config is different, and so is the machine which it will

learning experience for anybody who's new to the linux kernel which is 
well worth the effort to dig into kernel configuration.

 What is the purpose of installing a non-Fedora kernel, in your case?

Coming from SLS, slackware and yggdrasil way back in time, it's how it

on. I kept them over time, and they just work :-)

 Also, when the new security/bugfix patches land into the kernel tree, do
 you recompile it again, or what?

Most of the time, I recompile when a new stable rc hits
kernel.org. Quite often, the rc doesn't differ from the release, or it
differs in parts which doesn't affect me. So I'm just keeping the rc,
being too lazy to recompile :-)
  
 How much time do you devote to kernel maintenance, on a monthly basis?

I don't know. Sometimes it's more, sometimes less. I just copy my
things over, read lkml as usual, and let the machine do the job.

You can most probably have it where you want it to. If something

But of course, it can be the way for others. It's perfectly fine to build a

prefer.

 because (and I made a mistake earlier and shouldn't have suggested 
 that you use rpm) you can install your kernel with yum install ...
  and remove it with yum remove ...
 - and use it on more than one system if necessary.

I install my kernel using make install, and remove it by deleting
the sourcetree, kernel  co. in /boot and its modules in
/lib/modules/. It's what fits best for me.

You do not want to reply system data without a reboot anyway.

This is surely not an answer you would expect, but: Thunderbird is
