install evms on centos using yum

i'm refering this page

http://75.126.99.220/showthread.php?t=1062710

1) Get and *install rpmforge. http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

2) "sudo yum update". It'll take a while to add the new repository. It'll probably download some packages, too (30 megs in my case, but only 8 packages from rpmforge).

3) "yum search evms".

4) "sudo yum install evms.i386".

now installing :)

*install rpmforge: rpm -Uvh rpmforge*

ICS on windows 7

if you want to share internet connection using ICS from windows 7 to another windows 7 ICS connection, you maybe receive ip 192.168.137.1 is being used by other connection.

you can change this ip anyway into other address to prevent conflict. there are some registry hack available from this location

http://www.windowsnetworking.com/kbase/WindowsTips/WindowsVista/RegistryTips/RegistryHacks/ChangingtheDefaultIPAddressofICSinVista.html

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Services\SharedAccess\Parameters
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\SharedAccess\Parameters

change into different IP address to enable internet sharing from WLan to Ethernet. this works for me! :)

Installing git on Ubuntu

after several days wondering how to upgrade git on ubuntu (to test Chromium OS) this is my solution.

http://vandenabeele.com/install-git-on-Ubuntu-Jaunty

$ sudo apt-get build-dep git-core git-doc

$ wget http://kernel.org/pub/software/scm/git/git-1.7.0.6.tar.bz2

$ tar -xvjf git-1.7.0.6.tar.bz2

$ cd git-1.7.0.6/

$ make prefix=/usr/local all doc

$ sudo make prefix=/usr/local install install-doc

$ which git

/usr/local/bin/git

$ git --version

git version 1.7.0.6

doc is optional.

now i proceed to chromium install :)

Google chrome print very small - fixed

Currently i'm using google chrome to browse internet, make payment and print some recipt after payment has been made. there are problem here because google chrome does not have printing preference like other browser (ie & firefox). i'm not able to print into actual size and all my recipt are very small :)

the solution is disable fast draft print : http://www.google.com/support/forum/p/Chrome/thread?tid=761bf9c466615340&hl=en

for my cute PDF, (always using this for later printing) i use optimize for portability as follows:

1. press ctrl + P for printing menu

2. select CutePDF Writer printer

3. click Preferences > Advanced and click at PostScript Options

4. there are Optimize for speed as default value

5. Select Optimize for portablity and now you can print at actual size. (see screenshot)

thats all. hope this will help.

when i tried to browse internet it shows that page cannot be displayed or connection error. when try to ping, it replies when enter an ip address but cannot resolve ip when enter hostname or domain for example. ping yahoo.com ping google.com failed. ping 192.168.1.1 success.

after doing some search (using another computer, :( i've tried all the steps but not working.

final solution is easy.

1. go to network connection and right click at wireless network connection or local area connection. select properties.

2. click install > protocol > and click add

3. click Have Disk

4. type c:\windows\inf into copy manufacturer's files from.

5. select Internet Protocol (TCP/IP) and continue. this will reset your TCP/IP network configuration and all problems gone.

Menukar password root linux

Sekiranya server linux kehilangan password root atau telah ditukar oleh seseorang yang tidak dikenali, kita boleh menukar semula kata laluan root dengan mengikuti langkah di bawah. contoh diberikan bersama gambar yang dipetik dari laman web lain.

untuk rujukan bahasa inggeris sila lawati:

http://www.go2linux.org/fedora-centos-root-password-recovery atau

http://linuxgazette.net/107/tomar.html

1. semasa paparan GRUB dipaparkan tekan 'e' untuk mengubah command line

2. pilih pilihan kedua atau yang ada perkataan kernel dan tekan kunci 'e' sekali lagi.

3. tambah perkataan ' single' atau ' 1' tanpa penutup kata. pastikan ada ruangan kosong sebelum perkataan single atau 1. ini untuk masuk ke dalam sistem linux dengan pengguna tunggal.

4. sekiranya gagal, tambah init=/bin/bash di akhir perkataan.

5. tekan ENTER untuk teruskan. setelah itu tekan 'b' untuk masuk ke sistem linux dengan single user. anda akan masuk dengan akaun root

6. pada paparan root masukkan command passwd untuk menukar password root.

setelah itu, taip reboot untuk menggunakan server seperti biasa dengan password baru.
