Fix Packet Tracer Fonts in Ubuntu

packet tracer is a software simulation of cisco for learning / designing a network. for me it is very important because software is software that's one software that I need for school. after a few moments ago I decided to move from windows to linux. I need to find some software that I need. one of which is packet tracer.

then i get the installer packet tracer file with the extension. bin. I installed and successfully. after I noticed something strange on the font. I am handy tips for those of you who have problems like me. there are 2 ways completion.

first way

1. open terminal
2. sudo apt-get install ttf-mscorefonts-installer

second way

1. open terminal
2. sudo apt-get install libqtwebkit2.2-cil libqt4-script libqt4-qt3support libqt4-sql
3. sudo gedit /usr/local/PacketTracer5/packettracer
4. put a # in front of the line export LD_LIBRARY_PATH = $ PTDIR / lib

The second way gives fonts better than if you use the first way. both methods require an internet connection. if your ubuntu are not connected to the Internet. you have to do is download the following package of libqtwebkit2.2 4-cil, libqt4-script, libqt4-qt3support and libqt4-sql package along with its dependencies.

I recommend you download the package-package by using qdebdownloader. because qdebdownloader helps you to download all the dependencies package from the package you are looking for. then install it offline all packages with the command dpkg-i *. deb in the directory containing the package-package. then do step 3 and 4 on the second way. if you have any questions please leave your comment. hopefully useful:)

Permanent Aliases in Ubuntu

alias is one of the linux command used to create command alias to run the other command. aim to facilitate our work in the terminal. the problem is that we make with the alias command alias that is not permanent. therefore we must create a command alias again after the restart. to avoid that there is a way to make permanent alias. the following way

1. Open your ~/.bash_aliases file with text editor you like then add the alias you want. (If you don't have .bash_aliases, create a new one on your home directory)
example:
alias openfile = 'cat myfile.txt'

2. Uncomment these 3 lines on your ~/.bashrc file
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi

3. Restart your terminal, if it doesn't take effect you need to reboot system. I only need to restart the terminal to make the aliases take effect

good luck brother / sister :)

need to know! 
The system console, root console or simply console is the text entry and display device for system administration messages, particularly those from the BIOS or boot loader, the kernel, from the init system and from the system logger. It is a physical device consisting of a keyboard and a screen.

On traditional minicomputers, the console was a serial console, an RS-232 serial link to a terminal such as a DEC VT100. This terminal was usually kept in a secured room since it could be used for certain privileged functions such as halting the system or selecting which media to boot from. Large midrange systems, e.g. those from Sun Microsystems, Hewlett-Packard and IBM, still use serial consoles. In larger installations, the console ports are attached to multiplexers or network-connected multiport serial servers that let an operator connect a terminal to any of the attached servers. Today, serial consoles are often used for accessing headless systems, usually with a terminal emulator running on a laptop. Also, routers, enterprise network switches and other telecommunication equipment have RS-232 serial console ports.

On PCs and workstations, the computer's attached keyboard and monitor have the equivalent function. Since the monitor cable carries video signals, it cannot be extended very far. Often, installations with many servers therefore use keyboard/video multiplexers (KVM switches) and possibly video amplifiers to centralize console access. In recent years, KVM/IP devices have become available that allow a remote computer to view the video output and send keyboard input via any TCP/IP network and therefore the Internet.

Some PC BIOSes, especially in servers, also support serial consoles, giving access to the BIOS through a serial port so that the simpler and cheaper serial console infrastructure can be used. Even where BIOS support is lacking, some operating systems, e.g. FreeBSD and Linux, can be configured for serial console operation either during bootup, or after startup.

It is usually possible to log in from the console. Depending on configuration, the operating system may treat a login session from the console as being more trustworthy than a login session from other sources.
