Ubuntu 10 LTS The Best Linux Distro 5 Reason

Ubuntu 10.04 is another linux distro that was have big  ubuntu kernel change that i think Ubuntu 10.04 LTS is the best linux distro, why i think Ubuntu 10.04 LTS is the best linux distro? This reason is from my personal analysis and look from free open source linux distro.

What's different from ubuntu 10.04 if compared from another free open source (just personal reason), this is 5 Reason why ubuntu 10.04 be the best :
1. Speed up. Lucid Lynx just needed 2 second times from booting till your login screen. :-D
2. Stability. Thus lucid lynx is different from last version is OS Stability that i feel, as special as ubuntu 10.04 remix.
3. Hardware Support. This issue always be a scream for fisrt user that want to try linux because linux just little hardware support.
4. Security. Linux security is the best if we know to configuring it's, with Lucid Lynx 10.04 LTS this is a simple way to manage our security.
5. Soft Screen. This is personal feel, but this is make ubuntu 10.04 lucid lynx be the best linux distro from my personal view point.

Above is the best ubuntu that i see, how about you?

Active detect and close network linux redhat ports

Most important tasks is to detect and close network ports that are needed.

To get a list of listening network ports (TCP and UDP sockets), you can run the following command:

# netstat -tulp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name
tcp        0      0 *:auth                      *:*                         LISTEN      2328/xinetd
tcp        0      0 localhost.localdomain:smtp  *:*                         LISTEN      2360/sendmail: acce
tcp        0      0 *:ssh                       *:*                         LISTEN      2317/sshd

From the output you can see that xinetd, sendmail, and sshd are listening.

On all newer Red Hat Linux distributions sendmail is configured to listen for local connections only. Sendmail should not listen for incoming network connections unless the server is a mail or relay server. Running a port scan from another server will confirm that (make sure that you have permissions to probe a machine):

# nmap -sTU 

Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2004-12-10 22:51 CST
Interesting ports on jupitor (172.16.0.1):
(The 3131 ports scanned but not shown below are in state: closed)
PORT    STATE         SERVICE
22/tcp  open          ssh
113/tcp open          auth

Nmap run completed -- 1 IP address (1 host up) scanned in 221.669 seconds
#

Note that the above nmap command can take a while. If you remove the UDP port scan (without the option "-U"), then nmap will finish the port scan immediately. If you run it on the local machine it will also complete very fast. Also note that nmap might not show all listening network sockets if a firewall is being used to block ports.
From the output above you can see that the xinetd daemon is listening on port auth (port 113) for IDENT (for more information on this service, see below). You can also see that sendmail is not listening for remote incoming network connections, see also Securing Sendmail.

Another method to list all of the TCP and UDP sockets to which programs are listening is lsof:

# lsof -i -n | egrep 'COMMAND|LISTEN|UDP'
COMMAND    PID USER   FD   TYPE DEVICE SIZE NODE NAME
sshd      2317 root    3u  IPv6   6579       TCP *:ssh (LISTEN)
xinetd    2328 root    5u  IPv4   6698       TCP *:auth (LISTEN)
sendmail  2360 root    3u  IPv4   6729       TCP 127.0.0.1:smtp (LISTEN)

Click Applications==>Accessories==>Terminal and enter the following command :

sudo aptitude install libgtk2.0-dev libxml2-dev gettext libnss-dev libnspr-dev libgtkspell

and than, ENTER.
After that download canon driver here

Download these files to your home directory.

You must download Alien, so you can convert the .RPM files into .DEB files. Install alien using the following command

sudo aptitude install alien

To convert the .RPM files into .DEB files

sudo alien -d *.rpm

To install the printer drivers

sudo dpkg -i cnij*.deb

To install the scanner drivers

sudo dpkg -i scan*.deb

sudo aptitude install libpng3

sudo ln -s /usr/lib/libtiff.so.4 /usr/lib/libtiff.so.3

sudo /etc/init.d/cupsys restart

cd /usr/share/cups/model/

sudo lpadmin -p MP160 -P canonmp160.ppd -v cnij_usb:/dev/usblp0 -E

sudo apt-get install libxml1

At now the printer completely installed. But we need to download and install the scanner back-end.Get the scanner back-end from here.

Uncompress the downloaded file using the following command
tar -xvjf mp150-0.13.1.tar.bz2

cd mp150-0.13.1

make

sudo make install

(if asked to overwrite any files, choose Yes)

Install Driver HP LaserJet in Linux

One of Linux difficult is how to using printer hardware that not support by our distro. For HP laser jet has a little way to download and install driver for Linux OS. This is step by step how to install HP Laser Jet Printer :
1. Open your terminal and write this :
$ wget -O foo2zjs.tar.gz http://foo2zjs.rkkda.com/foo2zjs.tar.gz
2. Now unpack it, write at terminal :
$ tar zxf foo2zjs.tar.gz
$ cd foo2zjs
3. After unpack, now we must compile that file. Write at terminal :
$ make
Get extra files from the web, such as .ICM profiles for color correction,
and firmware. Select the model number for your printer:
$ ./getweb P1005 # Get HP LaserJet P1005 firmware file
$ ./getweb P1006 # Get HP LaserJet P1006 firmware file
$ ./getweb P1007 # Get HP LaserJet P1007 firmware file
$ ./getweb P1008 # Get HP LaserJet P1008 firmware file
$ ./getweb P1505 # Get HP LaserJet P1505 firmware file

Install driver, foomatic XML files, and extra files:
$ su OR $ sudo make install
# make install

(Optional) Configure hotplug (USB; HP LJ P1005/P1006/P1007/P1008/P1505):
# make install-hotplug OR $ sudo make install-hotplug

(Optional) If you use CUPS, restart the spooler:
# make cups OR $ sudo make cups

4. Now create printer entries for your spooler.

For Redhat 7.2/7.3/8.0/9.0 and Fedora Core 1-5 users:

# printconf-gui

For Fedora Core 6, Fedora 7/8/9/10/11, and Ubuntu 7.10/8.x/9.x users:

# system-config-printer

For Mandrake/Manrivia users:

# printerdrake

For SUSE 10.x/11.x users:

# yast2 printer

For Ubuntu 5.10/6.06/6.10/7.04 users:

$ sudo gnome-cups-manager
$ sudo make cups # IMPORTANT: gnome-cups-manager has a BUG in it

For low level testing, you can also create a "raw queue", which will accept "XQX" stream files as-is and send them directly to the printer.
