Which two daemons are part of the Samba suite? What does each do? SMBD: The smbd program provides Samba’s file and printer services, using one TCP/IP stream and one daemon per client. It is controlled from the default configuration file, samba_dir/lib/smb.conf, and can be overridden by command-line options. NMBD: The nmbd program is Samba’s NetBIOS name and browsing daemon. It replies to broadcast NetBIOS over TCP/IP (NBT) name-service requests from SMB clients and optionally to Microsoft’s Windows Internet Name Service (WINS) requests. Both of these are versions of the name-to-address lookup required by SMB clients. The broadcast version uses UDP/IP broadcast on the local subnet only, while WINS uses TCP/IP, which may be routed. If running as a WINS server, nmbd keeps a current name and address database in the file wins.dat in the samba_dir/var/locks directory. 2. What steps are required for mapping a Windows user to a Linux user? Set the username map parameter in smb.conf to point to the map file, frequently /etc/samba/smbusers, and assign a Samba password to the user 3. How can a system administrator add a Samba password for a new user? smbpasswd username 4. What is the purpose of the [homes] share? Should this share be browseable? Why? The [homes] share implicitly shares the home directory of each user without having to define specific shares. 5. Describe how Samba’s handling of users differs from that of NFS. NFS directory hierarchies are mounted by root and NFS maps users on the client to users on the server. A nonroot user mounts a Samba share and all accesses to that share occur in that users name.

Amr Moussa :: Essays Papers

Amr Moussa I am Amr Moussa. I currently represent the country of Egypt as Secretary General of the Arab League, but that’s getting ahead of myself. Allow me to take you back to my beginning. I was born on October 3rd 1936 (Medea’s Information files, 2002 pg 1). While I was growing up I studied law in Cairo, Egypt before I started my successful career as a civil servant. My duties as a civil servant began once I started in the office of Egyptian Foreign Affairs Ministry in 1958(Medea’s Information files 2002 pg 1). This was my first big break and I was going to take full advantage of it. In 1967, some 9 years later, I became the Egyptian Ambassador to India(The African Center, London 2002 pg 1). To me this was the break I had been looking for in my career. This was an opportunity I knew I had to capitalize on, and I did. I was also rewarded with permanent Representation to the United Nations in 1990(Medea’s Information files/Medea 2002 pg 1). Acting as the middleman between Israelis and Palestinians in 1992, when secret talks were going on, I gave my full support to the Declaration of Principles in September of 1993 to guarantee the Palestinian National Authority (PNA) of Egypt’s support. I was a supporter of the Israeli integration in the Middle East. I was very critical of the Israeli government for not having full support over the commitment to the peace process. I was also outraged at the lack of full support for not signing the new Non-Nuclear proliferation Treaty in 1995(Medea’s Information files 2002 pg 1). I have worked extremely hard my whole life to bring my country (Egypt) closer to neighboring countries such as Syria, Jordan, and Iran. Since I started on this journey, I have gained extensive ground to make such progress that is seen today. However there is still no guarantee that the relationships we have made will stand in future times of despair. I have been the Minister for Foreign Affairs in the Government of Egypt since 1991(The African Center, London pg 1). In 2001 I was relieved of my duties at Minister for Foreign Affairs. I was recently appointed to be Secretary General of the Arab League of States in May of this past year of 2001(The African Center, London 2002 pg 1).

The next types are breakwaters

There are a variety of techniques and efforts used to stabilize shorelines throughout the world and some are temporary and some are permanent. Structures built to protect a coast from erosion or to prevent the movement of sand along a beach are known as hard stabilization (Lutgens and Tarbuck, 2008).There are three common types of hard stabilization which are considered to be permanent techniques. The first types of hard stabilization are called groins. A groin is a barrier built at a right angle to the beach to trap sand that is moving parallel to the shore.The next types are breakwaters, which are structures designed to protect watercraft from the force of large breaking waves by creating a quiet water zone near the shore. The third type is a seawall. Seawalls are just that; walls built parallel to the shore to protect the coast and property from the force of breaking waves.Hard stabilization is usually very effective and a lot of the time too effective. Groins tend to sand-starve the longshore, breakwaters may allow sand to accumulate behind the structure due to reduced wave activity and seawalls causes the beach seaward side to experience significant erosion.Alternatives to hard stabilization are beach nourishment and relocation. Beach nourishment is replacing sand on beaches, however the downside to this is that is does not last and is expensive. Relocation is relocating storm damaged buildings and buildings at high risk, thus allowing nature to reclaim the beach. The downside to this is that people do not want to give up their ocean front property. (Lutgens and Tarbuck, 2008)I do not believe that urbanization and development of coastal area always contribute to shoreline erosion because people want to protect their property from erosion therefore doing what they can to prevent erosion. However, I also believe that sometimes people end up doing more harm than good with their methods used to prevent shoreline erosion from happening.References:Lutgens, F. an d Tarbuck, E. (2008).

Irony in Swifts A Modest Proposal Essay - 790 Words

Although I realize your concern, you have missed the point of this well thought out essay completely. Despite what you may think about A Modest Proposal by Jonathan Swift, this essay is a satire master piece filled with irony. Swift’s essay was not intended to convince people to eat babies, but to call attention to the abuses Catholic’s face from their well-to-do Protestants. He only uses eating babies in his essay to explain to the reader the impossible burdens the Protestants are imposing on the Irish Catholics and by making their life hard, they are making a life of a new born impossible. He makes his first point on page 411 when he tells the reader that eating babies is no problem for landlords because they have â€Å"already devoured†¦show more content†¦He is saying that Protestants are not caring and are ready to ruin the lives of many others. By saying that when asked as an adult, a Catholic would rather have been â€Å"sold at a year old†¦an d thereby avoided†¦misfortunes†¦ [and the] impossibility of paying rent† (416), he is again pointing out the mercilessness of Protestants. He is not saying that these people would like to be sold as food so cooking them up is acceptable, but bringing the point back to the fact that Protestants are being too cruel on innocent lives. Overall, Swift is also using irony by relating this unheard of cruelty to babies to cruelty animals. He suggests that buying children alive and â€Å"dressing them hot from the knife as we do roasting pigs† (411) is the best way to serve them. This was intended to tell the audience that the Protestants are basically treating the Catholics like animals with no regard to life. This carefully crafted technique lets the reader see how malicious the Protestants are actually being, and that they are killing Catholic babies alive by ruining any chance at a good life. Swift did not actually mean for people to go out and cook babies lik e pigs to get the most satisfactory, he simply meant that if you are going to treat them like pigs, you might as well eat them like pigs.
