how to make Latex Beamer Presentations
If you want to create overhead presentations (รก la Powerpoint) with LaTeX, you can do so by using Beamer class, which creates surprisingly professional and sophisticated documents that you can then display using any pdf viewer (e.g., such as Adobe Acrobat). The advantage of using LaTeX over a program like Powerpoint is that it doesn't require expensive software for either creating or displaying your presentation; it thus makes the presentation truly "portable".

To verify that the installation was successful, execute
The output should look something like this if everything is well
java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode)
If you have multiple JRE or JDK installed (e.g. 1.5.0 and 1.4.2) and want/need to switch between them, you can use update-alternatives to do so.
Example: Choosing which java executable to use:
Example: Choosing which javac executable to use:
And so on in that fashion for the remaining executables related to Java. You can look in /etc/alternatives to see what one can configure with update-alternatives.

Display all the interfaces you have on your server:ifconfig
Display all interfaces as well as inactive interfaces you may have:ifconfig -a
Assign the eth0 interface the IP-address 192.168.1.100 with netmask 255.255.255.0:ifconfig eth0 192.168.1.100 netmask 255.255.255.0
Assign the default gateway for eth0 to 192.168.1.1 (for example your router):route add default gw 192.168.1.1 eth0
Verify that you can reach your router (192.168.1.1):ping 192.168.1.1
Display the routing information with the command route to see if routing entry is correct:route -n
Check the status of the interfaces quickly:netstat -i
Show all active connections:netstat
Show all active TCP connections:netstat -t
DNS lookups (3 different ways) and displays the answers that are returned from the name server (To troubleshoot DNS problems):dig ubuntulinux.orgnslookup ubuntulinux.orghost ubuntulinux.org
Determine the network route from your computer to some other computer:traceroute www.ubuntulinux.org
View your ARP (used by a networked machine to resolve the hardware location/address of another machine on the same local network) Cache:arp
Remove any entry from the ARP cache for the specified host (for example 192.168.1.103):arp -d 192.168.1.103
Check traffic in network : tcpdump -n arp
Send out unsolicited ARP messages so as to update remote arp caches (for example 192.168.1.103):arping 192.168.1.103Shutdown a specific interface (for example eth0):ifconfig eth0 down
Activate a specific interfrace (for example eth0):ifconfig eth0 up
Stop all network devices manually on your system (Debian specific):/etc/init.d/networking stop
Start all network devices manually on your system (Debian specific):/etc/init.d/networking start
Restart all network devices manually on your system (Debian specific):/etc/init.d/networking restart
Networking configuration is stored in the following file:
