wicd + dnsmasq + opendns - opendns (ads) guides = faster browsing http://bit.ly/9d1Bcp - dennyhalim.com

wicd + dnsmasq + opendns - opendns (ads) guides = faster browsing

Fri, 19 Mar 2010 14:09:46 GMT

there are many many ways to speed up your browsing experiences.

one of many ways is optimizing your DNS server list.
each and every file on the internet is located on a certain (sub)domain.
so, each and every request of any file from your browser will need to query DNS servers first, before it can be fetch to your browser.

as you can see, DNS play significan roles in your browsing experience. if you're using firefox and see a lot of 'looking up someslowdomainname.com' then your DNS is slow.

here's how i speed up DNS lookup a little bit. first, install dnsmasq to do dns queries and cache all the results. thus repetitive lookup will perform much faster because the result is already in cache.

then, tell dnsmasq to do the queries to opendns to let it filtered out phising and malware sites. but, opt-out the opendns guides and block my local ISP ads.
edit /etc/dnsmasq.conf and add this lines:

#http://winware.org/bogus-domains.txt
bogus-nxdomain=92.242.132.11 #telkom speedy indonesia ads
bogus-nxdomain=67.215.65.132 #opendns guides
#bogus-nxdomain=208.67.219.135 #opendns blocked pages
#bogus-nxdomain=64.94.110.11 #verisign

last, must not pass this one, tell the clients (i use wicd to manage my linux networks), including browsers, messengers, etc.. to query local dnsmasq instead of the far away opendns servers.
edit /etc/resolv.conf.head and add these lines:

nameserver 127.0.0.1 #query local dnsmasq
#dnsmasq will query these. also, in case dnsmasq fail, all apps will query these too:
nameserver 208.67.222.222 
nameserver 208.67.220.220

if you need more redundancy, in case all your dns fail, add this to /etc/resolv.conf.tail

#google's 
nameserver 8.8.8.8 
nameserver 8.8.4.4

wicd will automatically merge dns from your router/isp between resolv.conf.head and resolv.conf.tail

now... our dns is much faster... what else can we do to speed up browsing? what do you do?

Archlinux faster boot

Sat, 06 Feb 2010 17:44:51 GMT

one great thing about archlinux is the rc.conf which simplify services configuration a lot.

instead of messing with lots lots of rc.X files, you only need to configure one single file for all bootup process.

also, this way, you have full control which services should startup first and which services can start later.

i move kdm service to start earlier so that i can have X starts while other services starts in background.
this is how i arrange the services/daemons:

DAEMONS=(syslog-ng @network hal wicd kdm netfs crond laptop-mode compcache)

or, you could also put a lot of @ in front of each service so it starts in background, as more Arch user use like this:

DAEMONS=(syslog-ng @network hal wicd @netfs @crond @laptop-mode @compcache kdm)

how is yours arranged?

minimal KDE / KDEmod on Archlinux

Fri, 05 Feb 2010 10:57:43 GMT

if you follow the instruction on kdemod installation, we're told to do 'pacman -S kdemod-minimal' to install minimal KDE.

but that need to download over 400Megs packages and that does not seems minimal for me. coz the Archlinux KDE minimal install, only need much much smaller packages:

pacman -S kdebase-workspace kdebase-konsole

so i guess, i can do the same thing with kdemod. which i did:

pacman -S kdemod-kdebase-workspace kdemod-kdebase-konsole

now, that's what i called a minimal install.

offloading wpmu themes and plugins to cdn, fast & easy, without plugins

Thu, 04 Feb 2010 01:08:12 GMT

one of many ways to speed up your wpmu is by offloading your themes and plugins url to CDN.

there are many plugins to let you do this. you can also use htaccess to rewrite all your /wp-content url to cd.

but i just found out, you can do it very easily without any plugins or htaccess rewrite. just edit your wp-config.php like this:

define( 'WP_CONTENT_URL', 'http://your.cdn.host/wp-content');
define( 'WPMU_PLUGIN_URL', 'http://your.cdn.host/wp-content/plugins');

that's all it.
now all your wp-content and plugins url will be change to your.cdn.host and no cost for htaccess rewrite or plugins processing.

upgrade fedora kernel without compiling

Tue, 05 Jan 2010 02:10:44 GMT

i hate compiling. even that gentoo, archlinux and freebsd makes it really very easy.
however easy it gets, i still hate compiling...

i got very recent laptop which have intermittent lan and wifi connection with default kernel.

this one-line is all it takes to upgrade fedora kernel without compiling:

su -c 'yum --enablerepo=rawhide update kernel*'

that's all it.
your kernel will be upgrade to the latest kernel from rawhide (fedora testing)

that fix my intermittent network connection.

light simple compiz alternative composite window manager

Sat, 02 Jan 2010 01:33:04 GMT

happy new year! wish you all blessed and peace!

introducing xcompmgr - sample X compositing manager.

xcompmgr is a sample compositing manager for X servers supporting XFIXES, DAMAGE, and COMPOSITE extensions. It enables basic eye-effects.

imho, this is very hidden 'treasure' of linux freedesktop xapps.

it's not much know or used. but once i try it, i like it a lot!

well, maybe it's not comparable to compiz (fusion). it's not that feature full. and most important (for me) it's not that heavy weight compositing champion.
i can just run compiz, gnome/kde and all the glory on my Turion II laptop. but i rather let all resources goes to kvm to use/run/test other linux/win/solaris/firewall/servers/etc.
so, i try to keep bare minimal fancy X stuffs on my system. i use fedora lxde spins in this lappy.

i like compiz. but as i said, it's overkill for me. and i need all the resource i can get for kvm. so looks around to find the alternatives. xfce is the well known lightest desktop with compositing.

not anymore...
now with xcompmgr, you can use whatever your favourite lightweight window manager and still can have cool compositing desktop.
tested with fluxbox, awesome2, fvm2, and openbox (with lxde). all works good. it's very light, fast and use very low ram and cpu.

to test it, just install xcompmgr and run it inside X. if you like it, you can put it into autostart so that it start everytime X starts.

xcompmgr -c -f -F &
man xcompmgr

yum remove all dependencies

Fri, 25 Dec 2009 22:51:00 GMT

playing with fedora these few days.

yum is great with it's delta package system. which only download changed file instead of the whole package.

one thing i dont like is that yum do not know what dependencies have been installed and should be removed.

debian aptitude works out of the box.
and we can add --auto-orphans to mandriva urpme

some people suggest 'package-cleanup --leaves' to list leaf node (package that no other package depends on).

i try that, and it list libvirt which is needed by virt-manager. so i cant fully trust that.

more googling i found yum plugin remove with leaves package.

su -c 'yum install yum-plugin-remove-with-leaves'
yum remove --remove-leaves package-tobe-removed

still need to test this

the making of opensuse lxde livecd

Tue, 08 Dec 2009 11:57:22 GMT

by request of users and FameWolf that tiredlessly gives positive feedbacks, here i present the making of my opensuse lxde livecd.

well... actually i dont see much to show...
anyway, here goes...

Create new appliance...
Choose ´Minimal X´
gives it cool name.
add repos. the only one required is lxde repo.
add packages. (see screenshot)
tune configurations
paste this into scripts

chkconfig --add boot.compcache
chkconfig boot.compcache on

yast2 sysconfig set DEFAULT_WM="startlxde"
yast2 sysconfig set DEFAULT_GUI="GTK"
yast2 sysconfig set DISPLAYMANAGER="slim"
yast2 sysconfig set DEFAULT_WM="startlxde"

echo 'default_user  polaris' >> /etc/slim.conf
#echo 'auto_login    yes' >> /etc/slim.conf
echo 'sessions startlxde,icewm' >> /etc/slim.conf
echo 'exec startlxde' >> /home/polaris/.xinitrc

usermod -G audio,video,floppy,cdrom,disk,dialout,modem,games,lp,pmount polaris

echo 'text/x-suse-ymu;/sbin/OneClickInstallUI' >> /etc/mailcap
echo 'text/x-suse-ymp;/sbin/OneClickInstallUI' >> /etc/mailcap

the scripts used to works on ´Run script at the end of the build´ section. now it wont works. so i duplicate it to first boot section.

that´s all it!

you can make your own distro or just download the ready to boot opensuse lxde livecd.

park and monetize idle domains

Sat, 21 Nov 2009 21:00:58 GMT

so you just registered a great domain name and have not (yet) any plan what to do with it.
what you do?

most people just do nothing and let their registrar make money by showing ads on their unused properties.

now you can take control of your own idle domain names. setup your own parked pages or redirect to parking services that can make yourself few buck even it's unused. you can even set it up for sales if you like...

i'll recommend one parking service if you have not got one yet: park or sell your domain names
yes that have my affiliate code.

well, if you only have a dozen domain or less, that's not too hard to maintain. just add your domain to your parking service and it's done.
but if you have more... it will takes a lot of time to add each and every domain you have to the parking service.

now, this is how i make it easy to add hundreds or even thousands of your domain name into parking service without you have to manually input them...

first, register to park or sell your domain names because they have great api that we need.

second, setup nsd name servers on your vps. why nsd? it slimmer, lighter, faster than bind and wont slow down your vps. here's i set it on debian:

aptitude install nsd3

third, configure nsd and setup php redirect script

replace the 'lid=' with your own code.

fourth, setup all your idle domains to use your new dns server. or, you can just point it to your php script.

that's it. now all your idle domains will be redirected to the parking service which will give you (not your registrar) few buck per month per domain without you need to set it up manually.

ubuntu restricted shell with lshell

Thu, 30 Jul 2009 07:34:03 GMT

lshell is a restricted shell, similar to rssh or ironbars, which you can use to restrict users shell. but rssh only allow scp/sftp and does not allow login to shell. lshell allow login, but restrict user to only few commands.
i tested this with my ubuntu perfect webserver setup. but i believe it's same steps to install on any linux.

wget http://downloads.sourceforge.net/project/lshell/lshell/0.9.5/lshell-0.9.5.tar.gz
tar xvfz lshell-0.9.5.tar.gz
sudo python setup.py install
chsh -s /usr/bin/lshell RESTRICTEDUSERNAME

o, btw. it python script. so make sure python is installed.
that's it.
simple, fast, easy.

after that, edit /etc/lshell.conf to configure lshell to suite your need.
the most important (for me) is the allowed and forbidden list of commands.

openSuse + Koffice2 + OOo3 + Kontact PIM = Office Konnect Linux

Thu, 23 Jul 2009 02:25:15 GMT

looking for the perfect linux desktop for office use?
so did i.

lucky me, i have access to susestudio. that allow me easily customize openSuse as i like it.

so far, i built openSuse lxde livecd, which is the linux minimal desktop that only have lxde and firefox. this one i use for most every computer i can put it on. then, add up apps that i need.
then from this, i made up kidSuse. the linux for kids. this is the one my kids (from 2yrs to 6yrs) are playing and learning with, everyday.

but i still missing something...
for office use, i can start with minimal desktop. but there's too much to add and when the internet slowing down, it could takes hours downloading all the packages...

so here's the Office Konnect distro for my own use. or if it suite you, it's free to take.

Download Office Konnect Linux 0.1.2

what's inside? the latest (preferred, stable) version of these apps:

OpenOffice.org
Koffice
Kontact (KDE PIM) and all its components
konqueror, kopete, okular, k3b, kde-utils, etc
wine

well, because there're so many kde apps, i just use the kde desktop instead of other lightweight options.

that's all i can think of for my office use.
anything missing? critics, comments, suggestions are all welcome.

always up-to-date pidgin and yahoo messenger connection problem solved

Sat, 27 Jun 2009 06:28:39 GMT

yahoo, msn, aim, icq, etc... always changing their protocol and always causing connection problem for third party messenger apps like pidgin.

while linux distro always stick to one apps version at their release and do not upgrade to latest release.

then, recently yahoo change their protocol again.
all these causing all ubuntu users cant connect to yahoo messenger.
you can use getdeb and install the current version. but then you need to manually update pidgin everytime new version released. or everytime you encounter another connection problem.

the only good solution is to keep your pidgin always update to the latest release version. the instruction on pidgin site also not very up-to-date and will not install gpg key for the repo.

this will keep your pidgin always up-to-date:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A1F196A8
echo deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu \     `lsb_release --short --codename` main | \
    sudo tee /etc/apt/sources.list.d/pidgin-ppa.list
sudo aptitude update
sudo aptitude upgrade

that's it.
everytime you do 'sudo aptitude update && sudo aptitude upgrade' you will get the latest release version.
