VPN options
by Keith Lofstrom
I am planning on running a Virtual Private Network from my Fedora
firewall out to a UML virtual colo (running RH9) at another site.
That site will be the place I present services to the world;
httpd, ssh, sftp, smtp. This is to comply with the "no servers"
and dynamic ip restrictions on my Comcast connection to the net;
if my firewall always drives an outbound connection to the
colocation site, I am not worried about changes of ip address,
and I am not opening any inbound ports.
There are a number of options for the VPN - the most attractive
are cipe ( http://sites.inka.de/sites/bigred/devel/cipe.html )
and FreeSwan ( http://www.freeswan.org/ ), though I am told that
one can do all this through an ssh tunnel. I would rather have
simple and secure than super-duper; I have plenty of bandwidth,
and will send outbound http and smtp from the firewall, so the
main bandwidth user will be incoming spam/b/b/b/b mail.
Anyone have some experiences to share about setting up VPN? Is
there anything about either cipe or FreeSwan that is likely to
break with FC1 or FC2?

nc missing option -z
by Suvayu Ali
Hi,
I used to use netcat to check if a particular host is up or if I have
internet connection before I run a few scripts. I would use the -z
option in particular. But now I see that has been removed:
$ nc -z imap.gmail.com 993 && sync-my-email.sh
ncat: invalid option -- 'z'
Here is the excerpt from the old manual page:
-z Specifies that nc should just scan for listening daemons, without
sending any data to them. It is an error to use this option in
conjunction with the -l option.
Any ideas what happened to it? What can I use as replacement?
Thanks for any ideas.

C/C++ Compiler Invalidly Turning Warnings into Errors?
by Stephen Morris
I have a driver for a wifi usb device that I need to compile because
there are no drivers in the kernel, which has been obtained from the
vendor of the device. When I attempt to compile the code the compile
fails on the grounds that some warnings are being translated into
errors. From my perspective these errors should not be happening
because, when a debugging module wants to time stamp the build, that is
not an error and is perfectly acceptable. How do I get the compiler to
stop producing these errors. The messages I get are listed below.

I wasn't searching using "Solved" and the only keyword 'kstartupconfig4'
And *that* answer does not work. My home dir was already 'user:user'.
I have also confirmed the chcon context is now
'unconfined_u:object_r:user_home_dir_t:s0' for /home/user
And it doesn't work! Still get the error and no login.

Even better are the stupid messes where there is NO default setting to
change. Google 'kstartupconfig4 error 3' No-one, and I mean no-one knows
what causes this, or how to fix it. (Well, if there IS a 'great expert'
who knows this, he's not talking). And what happens when you get this
error? You cannot log in as a normal user.
So I've been forced to log in as root for well over a month now on this
laptop. (Quick! Get the smelling salts! A grey-bearded pony-tailed guru
just fainted with an attack of the vapours!)
And the problem has existed since I "upgraded" to F11...I suspect it has
something to do with the fact that the /home partition was retained from
F10 and that the chcon context might have something to do with it, but
then, like pulseaudio, chcon has entirely too minimal a set of
documentation. And I didn't even know chcon existed until a week ago,
when it turned up as the possible source/answer to a completely
different question about httpd.
It is the lack of documentation which makes Fedora (and Mandriva, and
Ubuntu) an OS for experts only.....

The stories about Microsoft releasing code, was more of a another way to cover up for a GPL violation :(
http://www.theregister.co.uk/2009/07/23/microsoft_hyperv_gpl_violation/
http://www.osnews.com/story/21882/Microsoft_s_Linux_Kernel_Code_Drop_Resu...
Not really because Micro$oft wants to help out a rival or a plague like Steve Ballmer once said. The truth comes out sooner or later.

Micro$oft is losing out to google, Twitter, Facebook and others. In a last ditch effort. Micro$oft is releasing code to linux. Check out this at distrowatch.

I like comment 133. It sounds just about right. There are many nice comments there. BTW, Redhat also signed a deal with them, are they really falling off or are they the Borg that is portrayed in comment 133?

Ranter or evangelist?
by gilpel＠altern.org
Why is it that, when I insert an audio disk, I see it as an audio disk on
my desktop, but when I click it, GNOME shows the .wav files that are
present. No application is suggested, even under "Open", to play the
damned music. If I go to Application, sound and video, the first option,
"Audio Player", opens XMMS.
Great! I click the forward button... I'm presented with a list of the...
no, no, no! not the files on the CD, but the files in my home directory!!!
Wow, we're really moving forward! I painfully navigate to /media, there's
nothing in /media.
Let's check mtab, my DVD/CD is on sr0, I believe. Nope, nothing there.
Well, if the intend was to scare away Mac and Windows users, I would think
that the success rate is 100%. I've been using Linux for 8 years and even
"I" am scared! I do understand Fedora is for geeks, but would it make
their life that difficult if things kinda worked? Didn't anybody notice
that the present set-up makes absolutely no sense?
At least, normally, you should go to => System, Preference, File
Management, Media to select a default CD and DVD player. Still impossible!
No option to change anything. I wrote about this. Nobody replied.
Who's responsible for setting things this way? Is anyboby responsible
somewhere or is it "We do all this together in a haphazard way" ? If so,
never expect any significant market share for Linux. Radio-Canada will
continue to use Windows Media because "Linux is too hard for ordinary
people" (MSFT trademark).
You think I'm a ranter? I've been told this quite often. But, while some
people write code, I write to the Quebec Press Council.
I explain that a certain so-called journalist is just a Microsoft
sycophant. Every time he used Windows Vista, of course, there were a
few... almost bugs. but certainly no show stopper.
With Linux, the question is more complex. When a new version of Firefox
comes out, for instance, instead of waiting for the upgrade, he gets the
executable at Mozilla and, then, everything gets really complicated.
Of course, the Press Concil understands perfectly what's going on. I made
sure my basic complaint was very easy to understand: I explained the
journalist NEVER discussed the appropriateness for the State --
television, amongst others -- of using proprietary format and never
discussed tied sales. That's it, that's all.
Still, after counceiding that the Press organisation lawyers had well
understood my POV, the Council judged that the journalist gives a lot of
coverage to Linux -- they didn't elabore on the kind of coverage: they
can't evaluate, of course -- and, you know, given that Linux hardly has 1%
of the market share, they found the coverage was adequate.
So, I filed an appeal... and sent a copy to the Professional Federation of
Journalists... I got my appeal.
But the fight is far from over. The Press Council is heavily subsidized by
the employer of said journalist, and Radio-Canada, another member of the
Microsoft club. Seeing subsidies vaporize scares the shit out of those
learned men: they could lose their precious jobs!
So, they'll try every trick in the book to give a very mild tone to their
judgement. But I have a few other tricks in my book to set the records
straight, though having the support from the Linux community would
certainly help.
Cause... do you really believe I got any help from local coders for this
fight? I got none, absolutely NONE. Why? Cause I'm a ranter. In other
words, though I am not a programmer, when I see things that are not done
correctly, I say so. They tell me I should fix the bugs.
Why is it that there are so many programmers and I can't even set a
default application for reading CD and DVDs? While I'm alone to do what I
consider my job, why is it that the whole community doesn't get its act
together to do such simple things?
Sometimes I wished I could proselytize in a more positive way. I'd like to
tell Apple users that Linux equals or surpasses OS X in user friendlyness,
but it doesn't. It was like this ten years ago, it is still like this now.
Countrary to what we could think from the success of Steve Jobs at the
helm of Apple, in the Linux world, the only people who count are
programmers. They'll fix things... soon.
But Linux is not so young anymore. After 18 years, it has 1% market share.
I believe there are some organizational bugs that need to be ironed out.
For now, from an administrative POV, Linux is a merry-go-round that
doesn't make much sense.
What do you say, am I a ranter or an evangelist? Is it good for Linux to
be ruled by programmers, the alternative not being necessarily the
marketing department? :)
Red Hat has some clout. How come they don't say "We want a music player
that first detects CD files and plays them" and accept to include them on
the default CD only on this condition?
Etc., etc., etc.

Before seeing above response,
I had just tried smplayer and it seems to be working well
no skips
smplayer -playlist xxxxxxxxx.pls
and it comes up with a small window that has volume slider and mute
just what i want..
I havent tried it yet to play audio dvd
Seems like I can remove Totem
