from:"S Mathias"

Good morning!! :)

I hope that i can find a solution to my questions: 
I'm new to Fedora, but it seems it would be the "best" distro for Desktop use.
I already installed it, 256 MByte for /boot, and put all the rest in an 
encrypted LVM. [LV: swap, /root, /tmp]



lsb_release -a
LSB Version:    :core-4.0-ia32:core-4.0-noarch
Distributor ID:    Fedora
Description:    Fedora release 14 (Laughlin)
Release:    14
Codename:    Laughlin

yum list | grep -i Firefox
firefox.i686   3.6.12-1.fc14    @updates



1 - Flash player:

http://fedoraproject.org/wiki/Flash

Theres no exact documentation for Fedora 14. So I went to:

http://get.adobe.com/flashplayer/

Selected YUM for Linux, but then i saw:

"You may have to temporarily disable your antivirus software."

WHY? Why does a closed source app want a thing like that? Is it doing something 
"bad" to my pc? Ok. So i installed Gnash. "Solved"...



2 - http://www.youtube.com/html5

# yum install gstreamer-plugins-bad-free
Loaded plugins: langpacks, presto, refresh-packagekit
Adding en_US to language list
Setting up Install Process
Package gstreamer-plugins-bad-free-0.10.20-3.fc14.1.i686 already installed and 
latest version
Nothing to do
# 

But when i visit:

http://www.permadi.com/blog/2010/05/sample-webm-video-2/

It just puts an "X" with black background to the place, where the video is.

How could i play html5/webm? videos?



3 - https://addons.mozilla.org/en-US/firefox/addon/12714/ force-tls
Does this plugin work? E.g.: facebook could be "always" https, but with this 
plugin, it just uses http.
On a machine with windows xp/chromium/enforce ssl plugin facebook is always 
"https" - just an example.
Are there any Firefox plugins, that "enforce" SSL, if there any?



4 - Where can I find up-to-date offical docs ["not ask google"] about any 
further questions?

http://forums.fedoraforum.org/
http://fedorasolved.org/
has anybody more links? :O



5 - I read about SELinux. But what is the "best practise" / suggestion, where 
can i learn about it, how to use it, configure, etc. :O



Thank you in advance!

VirtualBox on Fedora 14

Good evening list! :)

I'm searching for two answers regarding two questions. [and there are two 
"P.S."'s]

Q1: How can i list all the available kernel modules?

Q2: I want to install VirtualBox on Fedora 14 [->how could i download the 
kernel source?]: 

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O 
oracle_vbox.asc
rpm --import oracle_vbox.asc
rm oracle_vbox.asc virtualbox.rpm
wget $(wget -q "http://www.virtualbox.org/wiki/Linux_Downloads"; -O - | perl -ne 
'print "$1\n" while (/href=\"(.+?)\"/ig)' | awk '/fedora14/ && /686/ {print}') 
-O virtualbox.rpm
rpm -i virtualbox.rpm

And then, the fun part: 

# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel modules [  OK  ]
Uninstalling old VirtualBox DKMS kernel modules    [  OK  ]
Trying to register the VirtualBox kernel modules using DKMS[FAILED]

P.S. 2: When i wanted to install VirtualBox, i tried this [when running in to 
the kernel source "issue"]:

Re: VirtualBox on Fedora 14

Ok, so after a fresh install: 

yum install dkms kernel-devel
sync
sync
sync
reboot
wget "http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo"; -O 
/etc/yum.repos.d/virtualbox.repo

oracle_vbox.asc
rpm --import oracle_vbox.asc

yum update
yum install VirtualBox-3.2

And here comes the part, thats not 100%

You're making things hard on yourself. Follow this link[1] and setup the yum 
repository. Then installing is as simple as:

# yum install VirtualBox-3.2
The other packages you need is the kernel headers (not the whole source) and 
dkms (dynamic kernel module support), i.e.:
# yum install kernel-devel dkms
 
And then,
 the fun part: 

# /etc/init.d/vboxdrv setup

[snip]
Try "service vboxdrv setup" instead. Not really the problem but from what I've 
read it's a more appropriate method.

You don't want to just download it, you want to install it. But as I said, you 
don't need the whole source, just the headers which is provided by the 
kernel-devel package. 



Thank you in advance! :\ [sorry, i'm a beginner in Fedora :\ ]
No problem!

"ultimate" backup choice

i have:
"SERVER A"
"SERVER B"

with "full root permisson" [ssh, etc]

each server has a folder.

i want to backup a folder in "SERVER A".

are there any backup methods, that meets these two requirements? :


1) running from e.g.: a cronjob

2) when running, it just checks the folder in "SERVER A" and "SERVER B". if a 
file/folder has been added/removed/modified in the "SERVER A"'s folder, then it 
copies/removes it/them to "SERVER B"'s folder.

please help!

Thank you in advance! [for any links, howtos :\ ]

theres a website [using https] with a self-signed certificate, and i'm just 
wondering, how could someone "set it throu ssh" [on the clients], so that the 
"This Connection is Untrusted" sign doesn't appear on the clients

Border protection for Fedora

2010-12-12 Thread S Mathias

I have a small, simple firewall "script": http://pastebin.com/raw.php?i=NChRyqVu

Can I ask the mailing list, that look at it for a few moments, and sort out 
the: 

 - unnecessary things in it [if it contains any, like are there solutions for 
write multiple destination ip's in one line?]
 - missing thing, that could be in a firewall, to make it _SAFER/BETTER_!

TODO's/Q's [please help!]: 
1) where do i have to put the "iptables-restore FROMTHEFILE" command [to set 
the firewall when e.g.: booting the pc] on Fedora?

2) what is the best application firewall under linux? [links for good howtos?]

3) do i need a proxy? [i can guess that, that the http proxy on localhost can 
filter the http, but what's with https? it's end-to-end encrypted :O]

4) can i do something with the: "$IPTABLES -A INPUT -p tcp --dport 2 -j 
ACCEPT" - i'm seeding distros on torrent, but are there any plus "options" to 
e.g.: only allow torrent traffic on port 2/input?

5) on line 68: "$IPTABLES -A INPUT -m state --state ESTABLISHED,RELATED -j 
ACCEPT" - when i put a "-p tcp" in it, it makes "funny" things - when i reopen 
my webbrowser, i "can't surf the net", so i can't put the "-p tcp" in it? :( - 
just to ensure only tcp comes IN. [why would i need anything else?? only OUTPUT 
udp needed, no? :O + icmp ping output..]

6) "is it safer", if i use a local dns cache? like "dnsmasq"? 

7) what does exactly "--state ESTABLISHED,RELATED" mean? why do i have to write 
this to the start of my firewall script?

8) how could i block packets from: destinatio ip 255.255.255.255?? "$IPTABLES 
-A INPUT -d 255.255.255.255 -j DROP" to the start of my script DOESN'T help :O 
i used wireshark to get this info.. the broadcast package was my routeros 
router.

sorry if i ask to much :\ but i need these answers :\ [and at least it would be 
archived]

THANK YOU for any help regarding these things!

openssl chat

2010-12-12 Thread S Mathias

i can use "natively" openssl for anonymous chat: 

# Chat: 
# server side:
openssl req -x509 -nodes -days 365 -newkey rsa:8192 -keyout mycert.pem -out 
mycert.pem

# server side - generate a self-signed cert.
openssl s_server -accept 52310 -cert mycert.pem

# client side - "127.0.0.1" is the IP of the server
openssl s_client -connect 127.0.0.1:52310


1) but how can i set it to require username/password? it would be a great chat 
tool
2) how can i transfer files with openssl? [again: with username/password?]

thank you for any ideas :\

p.s.: or it will be a firewall rule, to restrict to ip addresses in a list? 
those, who are only allowed to connect..

caching-nameserver SELinux

2010-12-13 Thread S Mathias

i just wanted to install a local caching dns name server:

yum -y install caching-nameserver

but it can't start, because SELinux is preventing it: 

http://pastebin.com/raw.php?i=V9GK49mJ

I already tried:

touch /.autorelabel
reboot

but it still doesn't starts :\ problems the same.

theres a "fix command":
setsebool -P domain_kernel_load_modules 1
should i try it? will my pc be "safe" after this command? :\

thank you

3 name server questions

2010-12-14 Thread S Mathias

lsb_release -a
LSB Version:    :core-4.0-ia32:core-4.0-noarch
Distributor ID:    Fedora
Description:    Fedora release 14 (Laughlin)
Release:    14
Codename:    Laughlin

1) where does a local caching-nameserver get's it's information, about dns?

cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver 8.8.8.8

so if i want information about foo.com, then if it's not cached, i ask the 
local caching-dns-server. it doesn't know, what is foo.com. so what does it do? 
it asks the second name server? the 8.8.8.8?

2) i just can't find where could i set that what is the largest cache size of 
the local dns server. how long does the local dns server stores the 
informations?


3) can i flush the dns cache? restart named?

thank you!

method? [are there unnecessary lines in it?] :

# FLUSH ALL RULES
$IPTABLES -F
$IPTABLES -t nat -F
$IPTABLES -t mangle -F

# ERASE ALL NON-DEFAULT CHAINS
$IPTABLES -X

3) are there any docs/howtos, [like the syn attack "1)" one], that could give 
me more "security" with iptables?

4) my firewall script is here [are there any errors in it?]:
http://pastebin.com/raw.php?i=R7QdiDd9

5) is there a command to get info, that how many packets went through e.g.: the

$IPTABLES -A OUTPUT -p tcp --dport 20:21 -j ACCEPT
or the
$IPTABLES -A OUTPUT -p tcp -m multiport --dport 80,443 -j ACCEPT
line? are there any statistics about it?



ps.: the local dns server was just a:

yum -y install caching-nameserver
chkconfig --level 5 named on

ps2.: and i found out, that if i use a local dns server, that local dns server 
will "get info" from the root servers!!! no more relying on google dns, or 
opendns!! hurraj! :) !!! made my day :)

ps3.: i found out why my computer hangs, after installing the cached name 
server:

http://lists.fedoraproject.org/pipermail/users/2010-December/388752.html

it was regarding the firewall but with my newest [ 4) ] firewall script, it 
works just fine

google chrome "big brother"

2010-12-17 Thread S Mathias

Google Chrome Terms of Service(Google Chrome executable), BSD (source code and 
Chromium executable except chromium 5 beta),BSD License with proprietary parts 
(source code and chromium 5 beta executable, as it integrates Adobe Flash 
Player 10.1[1])[2]
http://en.wikipedia.org/wiki/Google_Chrome
in my interpretation, this means Google Chrome is fully open-source, only the 
flash player has proprietary codes.
am i right, or i'm missing something?
i would be happy if someone could correct me.
thank you!!
*ps.: because "they" say google is the "big brother"

Change m...@every boot

2010-12-18 Thread S Mathias

lsb_release -a
LSB Version::core-4.0-ia32:core-4.0-noarch
Distributor ID: Fedora
Description:Fedora release 14 (Laughlin)
Release:14
Codename:   Laughlin

# uname -a
Linux a 2.6.35.9-64.fc14.i686.PAE #1 SMP Fri Dec 3 12:28:00 UTC 2010 i686 i686 
i386 GNU/Linux


I'm trying to do what was mentioned in the $subject:

echo -e '#!/bin/bash\n\nmacchanger -r eth0\nmacchanger -r wlan0' > 
/etc/rc.d/init.d/macchanger
ln -s /etc/rc.d/init.d/macchanger /etc/rc.d/rc5.d/S22macchanger
chmod +x /etc/rc.d/init.d/macchanger


S23 is the network manager, and i'm sure i'm in runlevel 5.

but the mac doesn't change at boot, and i can't see any log messages regarding 
it :(

Where should i put my script? or it doesn't have enough permission to change 
the MAC's?

Thank you for any help (or pointing to a howto)

2 Ethernet cabling question

2010-12-25 Thread S Mathias

Two questions that was not always clear for me [sorry for posting to this list 
:\]:

##

Q1) when cabling, is the color order important? like:

straight cabling:
A side: white-orange, orange, white-green, blue, white-blue, green, 
white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, 
white-brown, brown

could be eg.: like this??
A side: white-orange, brown, white-blue, green, white-green, blue, white-brown, 
orange
B side: white-orange, brown, white-blue, green, white-green, blue, white-brown, 
orange

##

Q2) again cabling.. i know what is the color order of straight and crossover 
cabling. BUT: what are the color orders, when i need to create physically two 
separated networks?

568B; straight; nic to switch:
A side: white-orange, orange, white-green, blue, white-blue, green, 
white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, 
white-brown, brown
--
568A; crossover; nic to nic: [it's not so important about from ~2005]:
switch the pairs: 1&2 with 3&6 on one side:
A side: white-green, green, white-orange, blue, white-blue, orange, 
white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, 
white-brown, brown
--
one cable, two straight networks:
A side: 
I.: 
II.: 
B side: 
I.: 
II.: 
--
one cable, two crossover networks:
A side: 
I.: 
II.: 
B side: 
I.: 
II.: 
--
one cable, one straight and one crossover network:
A side [straight]: 
I.: 
II.: 
B side [crossover]: 
I.: 
II.: 
--
one cable, one crossover and one straight network:
A side [crossover]: 
I.: 
II.: 
B side [straight]: 
I.: 
II.: 

##

Thank you for any pointings, links, or specific answers.

Happy Christmas!

4 questions Regarding Fedora 14

A few questions regarding Fedora: 



1) Is there any method to customize a Fedora Install iso?
i download from fedoraproject.org -> i do some "magic" to the iso -> custom iso 
done, installable

i'm thinking about like this: 

https://allmyapps.com/
http://ninite.com/
http://www.freenew.net/

but not web based [and not windows..], because i want to do plus things with a 
normal fedora, e.g.: 
 - plus repos [rpmfusion]
 - plus packages [from e.g.: rpmfusion, other, like google chrome]
 - pae kernel
 - small setting like chromium extensions, settings for them

-> and then, when i install a Fedora from the custom iso cd, i don't have to 
download/install packages/set things

how can i customize an iso like this?



2) is there a "gconf-editor" like "thing" under Fedora? [under ubuntu, you can 
set many-many things through it]



3) there is a file under ubuntu..:

/etc/modules

where i can type the modules what i want to load at boot. is there something 
similar under fedora for it?



4) there aren't any "tofromdos" package under fedora? how can i convert files 
that have unix eols?



thank you for any answer [sorry for asking this kind of things] and Happy 
Christmas!

Let's talk about yum and p2p in Fedora

Are there any active project about it?

like:
http://www.camrdale.org/apt-p2p/
for Debian.

Why doesn't it have viability? Why does it have?

What are the security issues regarding it?

e.g.:
No port forwarding is needed in p2p (no need for open ports [? fixme]):
http://samy.pl/pwnat/ - these kind of projects will be more prevalent, as the
isp's will show up with the Large Scale NAT's -
http://tech.slashdot.org/story/10/12/17/2226230/Carrier-Trick-To-Save-IPv4-Could-Help-Spammers
- soon we will run out of ipv4 addresses.

Yum does the gpgcheck, so we just need audited code, that does the p2p part.
(i'm not a developer, sorry).

Remember this video(?): Twitter - Murder Bittorrent Deploy System
http://vimeo.com/11280885

Common sense: if i need to spread lot's of files no matter small or big, to
many-many-many-many pc's, then i would give a 10 Mbit line to the master
server, and the remaining job is done by the people, so that in this way, they
could contribute to the project.

The Fedora installer could contain a question: how would you like to receive
updates? [if e.g.: GNOME is installed, the updates would be "forced*", because
it's likely not a server, just a desktop pc] - and the answers would be: by
http or by p2p (or p2p with encryption)

What is you're opinion? Objection? Please tell me, because i just can't
understand why doesn't this brilliant technology/method spreads. It would be
very-very scalable.

+ if i go to the main website, and click "Get Fedora"

https://fedoraproject.org/en/get-fedora

it would need to accentuate the ISO download by torrent, not http, the servers
would be way more "relieved", and ready for any expected, or unexpected loads
(ddos, a version of Fedora is out, growing number of Fedora users).

I'm sure there would be many Fedora or other RPM based distribution users, who
would happily seed the packages. Broadband connections, HDD's are cheap in 2011.

*by forcing i meant it should install updates without asking, the primary
security relies on that the packages are up-to-date or not.

**_I LOVE FEDORA_, i just wanted to write down my opinion, sorry

Thank you for reading and have a nice day.

whats wrong with my internet connection checker script?

$ false && false || echo hi

$ ping -W 1 -c 4 google.com >& /dev/null | grep -q "100% packet loss" && ping

internet connection"
no internet connection
$
ping -W 1 -c 4 google.com >& /dev/null | grep "100% packet loss"
$
ping -W 1 -c 4 www.yahoo.com >& /dev/null | grep "100% packet loss"
$



...both sides "false", because they have no output, because google.com and 
www.yahoo.com is reachable.
how come it writes "no internet connection"? [at the longest line]
i just want a "oneliner" that checks if theres "internet connection" or no. :\

where did i screw up? 8)

Re: Let's talk about yum and p2p in Fedora

theoretically there are Unique Local Addresses (ULAs)

http://www.ripe.net/ipv6-address-types/

but i think when ipv6 will be widely used [don't know when:D we got about: 49 
days? hmmm... - https://ipv6.he.net/statistics/ ] "they" want that, that every 
computer must have a public ipv6 address, so that it can be natively accessible 
by the "outside world" [fixme] - so computers must have good firewalls... i 
hope that all the distributions, linux, bsd, everything will come with these 
default firewall settings in the future, to ensure security, e.g.:

recursively count the words occurrence in the text files

2010-12-30 Thread S Mathias

I just can't google for it:

I'm searching for a "bash" "one liner" (awk, perl, or anything) for this: 

there are text files, in several directories: 

mkdir one
mkdir two
mkdir three

echo "word1 word2 word3" > one/asf.txt
echo "word2 word4, word5" > one/asfcxv saf.txt
echo "word1. word2" > one/dsgsdg.txt

echo "word6, word3!" > two/sdgsd dsf.txt
echo "word6" > two/ergd.txt

echo "asdf, word2" > three/werdf.txt
echo "word7, word8 word9 word10" > three/qwerb erfsdgdsg.txt
echo "word4 word3" > three/web erg as.txt

so it does the magic* "recursively":

$ SOMEMAGIC > output.txt
cat output.txt
asdf 1
word1 2
word2 4
word3 3
word4 2
word5 1
word6 2
word7 1
word8 1
word9 1
word10 1
$



*recursively count the words occurrence in the text files like: "word1 2"
can anyone point to a howto/link? [re: i just can't google for it :\]

available.

The problem is: e.g.: facebook...

if i go to 
https://www.facebook.com/

that's ok, it's https.
But all the links are "http" on the site..
if i click on a "http" link, it will request the page on "http", and THEN it 
switches to "https". Heres the problem. 

How/where could i write a privoxy rule, to rewrite all the "http" links to 
"https"? [so that it would by always trully over https]

Are there any "general" rules (with privoxy), so that i don't have to write 
rules / site? 

with the KB SSL Enforcer its always first http, then it recognizes that the 
site can do https, than it switches to it. But i want to "bypass" the http part.

thank you for any information

Happy New Year!

variable in loop

2011-01-02 Thread S Mathias

$ ASDF=hello; a=0; a=$(( 70 - $(echo $ASDF | awk '{print length}') )); echo "$a 
$ASDF"$(for i in {1..$a}; do printf "."; done)
65 hello.
$ 


Why doesn't it print:
65 hello.

WHY? 

if i put it in "< pre >", then it's good.
but if it isn't in "< pre >" then the lines ends are random. why dont they end 
in the same vertical line?

How to install LibreOffice

http://en.wikipedia.org/wiki/LibreOffice

since OpenOffice on a regular Fedora 14 _always_ freezees (when want to do 
something in the menu, it's useless..)

What's the most "offical" way [howtos/links/tips] to install LibreOffice on 
Fedora 14/i386?

Thank you!

check, that a script is in a folder

$ echo ${PWD##*/}
somefolder
$ if "${PWD##*/}" -eq "asdf" > /dev/null; then echo "this is the asdf folder"; 
else exit 1; fi
bash: notthatfolder: command not found...
this is the asdf folder
$ 


So i just want to check that i'm in an exact folder. e.g.: "asdf"

What's wrong with my one-liner?

I just want to check, that a script is in a folder, and if it isn't, then it 
exits

Re: check, that a script is in a folder

solved:

if ! [ "${PWD##*/}" == "ASDF" ]; then echo "error: not the ASDF dir"; exit 1; fi

when will GRUB boot from an encrypted LVM?

When i install my laptop, i always encrypt all my HDD, except the "/boot", 
because the GRUB shipped with Fedora 14 won't boot from "/boot" if it's 
encrypted.

Does anybody know, when will Fedora support the "full encryption"? - When will 
it support booting from an encrypted "/boot" too?

Thank you for any links, pointings!

Let's talk about HTTPS Everywhere

Ok. It's a Firefox Add-on:

https://www.eff.org/https-everywhere

Questions:

1) But: Why can't i find it on the offical Firefox Add-ons site?: 
https://addons.mozilla.org/en-US/firefox/

2) Did anyone audited the "HTTPS Everywhere" code?

3) Can someone trust this Add-on? Is it safe to install/use?

4) If it's so great why isn't it more prevalent?

What's youre opinion? Or answer? :\

Thanks!

How to use this adblock rule?

I'm using Google Chrome on Fedora 14:

$ lsb_release -a
LSB Version: :core-4.0-ia32:core-4.0-noarch
Distributor ID: Fedora
Description: Fedora release 14 (Laughlin)
Release: 14
Codename: Laughlin
$ yum list | grep -i chrome | head -1
google-chrome-stable.i386 8.0.552.237-70801 @google-chrome
$

with this add-on:
https://chrome.google.com/extensions/detail/gighmmpiobklfepjocnamgkkbiglidom

I created a TXT file:
$ cat list.txt
[Adblock Plus 1.1]
! comment here
http://*.facebook.com/*
$

and i putted it on my domain, and subscribed to it, with adblock.
ok...
Why doesn't it blocks "www.facebook.com"?
I just can't find anything usefull on: http://adblockplus.org/en/filters
