Net-SNMP Tutorial

Just followed good tutorial to configure Net-SNMP >> click here

Anyway, I experienced error while 'make' where  I got this error >>/usr/bin/ld: cannot find -lperl

I find the solution here

First, locate libperl.

Output:

/usr/lib/libperl.so.5.10
/usr/lib/libperl.so.5.10.0

...

(or similar)

Create soft link;

sudo ln -s /usr/lib/libperl.so.5.10 /usr/lib/libperl.so

Make sure the link is in the /usr/lib **same directory with the link point. 

That's all. Thank you.

Streamyx: Sharing Internet on Fedora 12

I'm using streamyx for Internet connection at home. I've a laptop with an Ethernet card and a wireless card. Then, I started to google on how to share internet connection with other laptops using wireless connection since my LAN card is occupied with streamyx cable.

For setting up my machine as a gateway, it quite similar to previous post here, but it can simply be done by configuring firewall. Then, we can create an Ad-Hoc connection so that other machines (client) can simply connect to my laptop without the need of access point. In addition, in order to automatically configure IP address, gateway and DNS server address on client machine, we can set up DHCP server in the laptop (gateway machine). Following are the steps for make it works :

Note that all configuration is done on gateway machine.

Step 1: Connect to streamyx

Right-click on network manager applet, then choose 'Edit Connections..'

Select DSL tab and click 'Add' to add new connection. Then rename connection name to 'streamyx' or anything you want. Enter your username, password and service as shown in picture below. Tick connect automatically if want to allow connection on startup. Click 'Apply' to finish

Click on applet again, and now streamyx connection should be appear under 'Wired Networks'. Select to connect.

Step 2: Configure Firewall (from this step, all need to be done as root)

Open terminal and type

$ su

# system-config-firewall

Select 'Masquerading' and tick as bellow (thanks to KageSenshi)

Step 3: Setup DHCP server

First, install dhcpd (in fedora 12, dhcp package is using version 4)

# 'yum install dhcp

Check your DNS server to be used in dhcp configuration file

$ less /etc/resolv.conf

Output should be appear like this

# Generated by NetworkManager

nameserver 204.177.0.3

nameserver 204.177.1.12

Then, edit dhcpd configuration file (use familiar text editor such as gedit, vi or nano)

$ su -c 'gedit /etc/dhcp/dhcpd.conf'

Then, make it similar as bellow and match the address of DNS at 'option domain-name-servers'

# beginning of file

default-lease-time 86400;

max-lease-time 604800;

authoritative;

ddns-update-style interim;

option domain-name-servers 204.177.0.3

,204.177.1.12

;

subnet 192.168.1.0 netmask 255.255.255.0 {

range 192.168.1.1 192.168.1.5; # only 5 person can connect

option broadcast-address 192.168.1.6;

option routers 192.168.1.1; # gateway address

}

# end of file

Step 4: Create an Ad-Hoc connection

Enable wireless connection, then select 'Create New wireless Network'

Choose any wireless security you want or simply choose none. Click 'Create' to finnish.

Again right-click on the network manager applet and choose 'Edit Connections'. Then, under 'Wireless' tab, select your connection name and edit as follow

Click on applet, and select 'Connect to Hidden Wireless Network' and connect.

Finally, restart dhcp server

# sudo service dhcpd restart

Note that you need to connect to the created ad-hoc connection first (in my case, it is 'anyname') before you can start dhcp server.

Now, everyone near to you can see you Ad-hoc connection. Configure client's IP address using 'automatic configuration'. Once they connect to your ad-hoc connection through WiFi, they can surf to internet and facebooking all the time :P

IIUM FM

I'm IIUM student :) and I'm glad that IIUM has it own radio, which is broadcasting over the Internet. Users could simply go to this page http://livestream.iiu.edu.my/iiumfm/ and it will stream the radio using supported player in web browser. Nice huh?.. Hehe.

Beside that, for Linux user, you can simply use Rythmbox as follow:

Step 1: Make sure plugins are installed

ubuntu user,

$ sudo apt-get install ubuntu-restricted-extras

and fedora,

$ sudo yum install gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-ffmpeg

It is also necessary to install a bunch of codecs in here

Step 2: adding link

open your rythmbox, go to menu 'Music',click on 'New Internet Radio Station' and add this url

mms://livestream.iiu.edu.my/iiumfm

Then, go to side bar on Radio, then double click on the new added link.

That's it. Enjoy ;)

Fedora: Change Root Directory of Httpd

I recently try to install apache on fedora 12. I need to change the root directory to ease me editing file and avoiding permission. It is quite different when I was configuring on ubuntu. After read through several forums I come to this post. So, I won't be crazy for the next time.. haha

The default root directory is at /var/www/html. In my case, I want to change it to /home/user1/web.

Step 1: Edit apache configuration file (as root)

# gedit /etc/httpd/conf/httpd.conf

Find these two lines

DocumentRoot "/var/www/html"

...

...

#

# This should be changed to whatever you set DocumentRoot to.

#

<Directory "/var/www/html">

Then, change to

DocumentRoot "/home/user1/web"

...

...

#

# This should be changed to whatever you set DocumentRoot to.

#

<Directory "/home/user1/web">

Save and close this file.

Step 2: Changing permission

# chmod 711 /home/user1

# chmod -R 755 /home/user1/web

This step is necessary since in fedora, httpd process will be executed by user 'apache', thus permission need to be change.

By default, the permission for each user directory is drwx------, so that other users can't access to files in this directory and its subdirectories.

# setsebool -P httpd_enable_homedirs 1

# chcon -R -t httpd_sys_content_t /home/user1/web

Note: httpd by default is not allowed to access users home directories, see this page

Step 3: Restart apache

# service httpd restart

Hope this will help a little bit :)
