...IT 302 LINUX ADMIN PROJECT I chose to do my final project on the Samba server, such as how to set up the server, security, and maintenance. Samba “is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.” (source1) The whole purpose of the samba software is to make it possible to operate on many platforms. To install the server you would use the yum command in terminal. You then would enter su for the “super user” to install files as root. Then create a new directory containing three empty files which you'll share. While logged on as root create the new directory “/smbdemo” using this command “mkdir /smbdemo”. Then you would change permissions on the new directory to 770 with the following command “chmod 770 /smbdemo”. Now you navigate to the new directory with “cd /smbdemo” for the command. Add three empty files to the directory with the following command “touch file1 file2 file3”. Next step one would most likely add a user to the server. You do this first by “adding users to the Samba database in order for them to have access to their home directory and other Samba shares.”(source2) Using this command “smbpasswd -a ” you will then be able to add a new samba user. The user must be an existing Linux user or else the command will fail. Then if you “perform the following...

...Race and Struggle of Samba Samba exists throughout Brazil, peculiarly in the states of Bahia, Mahranhão, Minas Gerais, and São Paulo. Samba has two popular forms of expression: music and dance. A majority of people identify samba as the musical expression of urban Rio de Janeiro. Although samba is commonly identified with Brazil, the start of samba begins in Africa. According to Marc Hertzman, the origins of samba in Brazil can be trace back to the 1800s-a time when Brazil was still in the process of finding its own national identity. After Brazil freed the last of its remaining slaves, Brazil faced racial and economic divides, but with all this issues samba emerged as a building block of national identity. Samba is something unique that could be embraced by all Brazilians. Samba had an impact on Brazil as nation, but also it had an enormous impact on the individual and the African-Brazilian population. Throughout the world’s history, music has had the capability to tell the story of many slaves. Slaves in both the United States and Brazil had slave hymns. For example, the famous song Wade In the Water, which now commonly associated with the Underground Railroad. Once slavery ended, the sounds of those who were discriminated against changed. In the United States, slave hymns became the sound of jazz and the blues and in Brazil, samba was created. Samba is a word that is believed to come from the West African Bantu word, meaning “to pray” or “to invoke the spirits...

...influences. Capoeira - A style of martial arts developed by Brazilian slaves in the 1700s. Capoeira was developed surreptiously, with practitioners pretending that they were taking parts in dances, when in fact they were practicing their kicks and blows. Thus, there is also a whole style of capoeira music which goes along with the martial arts culture. Choro - An improvisational instrumental style from the late 19th and early half of the 20th Century. Similar to New Orleans trad jazz, choro was closely connected with the early development of samba, and is typically played by a small ensemble -- over the years the instrumentation has expanded to include more instruments, such as clarinet and mandolin... Early stars of the genre include flautist Pixinguinha, mandolin player Jacob do Bandolim, and guitarist Garoto. Forro - Upbeat, catchy dance music from the Northeast of Brazil. Usually features an accordion, and syncopated rhythms similar to samba. In some ways, forro is analagous to mariachi in Mexico, or cumbia music in Columbia: although a few artists (such as...

Carnival is a traditional festival of decadence before Lent begins, it is celebrated widely across Brazil. Rio de Janeiro and Salvador host huge parades involving performers who spend months preparing. Local community bands play throughout Rio’s neighborhoods for two weeks preceding the festival, also fancy balls take place throughout the city’s more upscale venues, this is called ‘blocos’. Blocos has two things that the citizens of Rio enjoy the most, this being The Copacabana Palace Ball and crowding the streets to watch the Samba School Parade from Sunday night into early Monday morning.

...mariachi. Mariachis origin is Mexico. Linda Ronstadt is known for promoting her mariachi music in North America. In her music the vocals are very prominent which reflects the ranchera style of mariachi. Mariachi has the stereotype that is connected to images such as sombreros. It is also said that all Mexican music is the same, which is untrue. Samba- The origin of this style of music is Afro-Brazilian and from Rio. The instruments that are primarily used in samba are the agogo, tambourines, reco-reco, and drums. The majority of the instruments are percussion based. The culca is the most distinctive instrument used in samba. It has a stick inside of it and uses a moist cloth. When the stick is put in motion its rubs the inside to produce different sounds. Brazil first viewed samba as an ill-mannered dance that was done by low-class citizens of Rio de Janerio. When Getulio Vargas took power he looked at samba as positive and used it to unify Brazil. Samba was found mostly when Carnival took place. It wasn’t until Vargas came along and made Carnival a national event and supported samba schools. Not only did he support the samba schools, he also offered public funds to help the school financially. Vargas was a cultural icon for this style of music. Tango- This style of music is from Argentina. The istruments used in this music are the violin, guitar, flute, piano, and the bandoneon. The bandoneon is the most important instrument used in tango because it is made up...

...IS 3440 Discussion 6 As the Linux system administrator of insurance company Secure All, Inc., you need to design firewall rules for the organization’s bastion host file sever, which uses Samba. Located on the LAN the sever should allow Web application access for it’s online transaction platform to mount the filesystem, using a Linux computer as a gateway between a private network and the internet. Any internet connection whether it be a dial-up PPP, DSL, cable modem or a T1 line can be used. In the case of most dial-up PPP connections and cable modem connections, only a single IP address is issued allowing only one computer to connect to the internet at a time. Using Linux and iptables / ipchains one can configure a gateway which will allow all computers on a private network to connect to the internet via the gateway and one external IP address, using a technology called "Network Address Translation" (NAT) or masquerading and private subnets. Iptables/ipchains can also be configured so that the Linux computer acts as a firewall, providing protection to the internal network. Using NAT a bastion host should allow administrators to access Samba and SSH for remotely managing the server through NAT or PAT. These two filter methods will allow for a one way only gateway that is only accessed through certain ports or network addresses. Using this sort of port or network address filtering administrators can access the Samba server to perform administrative tasks, while...

...Learning Objectives and Outcomes <!--[if !supportLists]--> <!--[endif]-->You will be able to explore design and firewall rules for a bastion host. <!--[if !supportLists]--> <!--[endif]-->You will examine how a bastion host allows administrators to access Samba and Secure Shell (SSH) for remotely managing a server. Assignment Requirements As the Linux system administrator of insurance company Secure All, Inc., you need to design firewall rules for the organization’s bastion host file server, which uses Samba. This server is located in the local area network (LAN) with the network address 172.16.0.0/12 and subnet 255.240.0.0. The server should also allow Web application access for its online transaction platform to mount the filesystem. The Web application resides on the Web server located in the demilitarized zone (DMZ). This server has two interface cards. One card, which is for the traffic from the DMZ firewall, is linked to the wide area network (WAN). This card’s IP address is 192.168.1.5. The other interface card has the IP address 172.16.1.5 and is linked to the LAN. Which firewall rules should be written using iptables for the server hosting Samba? Discuss and suggest firewall rules to allow administrators to remotely manage the server using SSH. Use the concept of “default deny” when designing the rules. Participate in this discussion by engaging in a meaningful debate regarding the firewall rules that can be written using...

...Exploring Linux Operating Systems What is Linux? Linux is an Operating System for a computer; it is like other Operating Systems such as Windows and the OS X for MAC. Linux was created in 1991 and has been found on many different systems like Super Computers, cell phones, and even the New York stock exchange. What sets Linux apart from other Operating Systems is that Linux is made by several different companies. According to www.linux.com over 3,200 developers have from 200 companies have contributed to the kernel which is just a small piece of the distribution. How is Linux used today? While other Operating Systems are very limited to personal computing devices, Linux is not limited it can be found on many different things. Linux had its start as a server Operating System but is also one of the only Operating System that can be found on more than just a personal computer. Some of the different things it can be found on taken from www.linux.com “These are just the most recent examples of Linux-based devices available to consumers worldwide. This actual number of items that use Linux numbers in the thousands.” www.linux.com File Editors Coming from a Windows Operating System pretty much my whole life, which means I only have experience with GUI editors such as Notepad from Windows.

Storage capacity on a computer is measured in bytes. A byte is composed of 8 bits and can store one character. Computers are capable of storing many characters, and storage is typically determined in megabytes (MB), 1,048,576 bytes, and gigabytes (GB), 1024 MB. * Many companies do not provide device drivers that support Linux. Instead, they rely on the free software development community to develop the appropriate drivers. For this reason, the newer a hardware device is, the less likely it is to be supported. * Linux OSes have a much lower threshold than Microsoft's Windows 7 and Windows 8 and Apples's Mac OS X. So system resources are less of an issue than system compatibility. That means you can run the latest Linux OS without having to buy a more expensive new computer. b.
