Samba allows Linux servers to communicate with Windows machines using the SMB protocol. It lets Linux systems act as file and print servers for Windows clients on a network. Samba consists of client and server components that allow Linux machines to access Windows shares and Windows machines to access shared resources on Linux servers. The Samba configuration file smb.conf is used to define global parameters and shares. Windows machines can then browse and connect to the shared folders and printers using the SMB protocol.
Network File System (NFS) allows users to access and share files located on remote computers. It builds on ONC RPC and has evolved through several versions. NFS uses a client-server model where the client makes RPC requests to access files on the NFS server's file system. This allows for flexible sharing of resources but introduces some security and performance disadvantages compared to a local file system. Overall NFS is a widely used distributed file system protocol.
Network File System (NFS) is a distributed file system protocol that allows users to access files over a network as if they were on a local disk. NFS was originally developed by Sun Microsystems in 1984 and is now maintained by the IETF. NFS uses RPC calls to issue requests from clients to servers and maintains a stateless design to simplify crash recovery. While easy to set up and administer, NFS has limitations regarding performance, scalability, security and file locking.
Samba is an open source software suite that allows file and printer sharing between Linux/Unix systems and Windows clients. It uses the SMB protocol to provide services to SMB/CIFS clients. The document discusses installing and configuring Samba, including creating a smb.conf file to define shares, users, and permissions. It also covers connecting Samba clients and basic troubleshooting.
NFS allows remote access to files on a server from client machines. It uses stateless servers so server disruptions don't affect clients, and clients can continue accessing files after a server reboot. The client parses file paths and looks up components individually to accommodate different file naming conventions. NFS adopted UNIX file semantics and operations like open, read, write, and close, along with basic file types and permissions.
Linux is an open-source operating system based on Unix. It is robust, scalable, stable, and secure. Linux was originally developed in 1991 by Linus Torvalds and is freely available. Common Linux distributions include Red Hat, Debian, SUSE, and Gentoo. When installing Linux, important steps include identifying compatible hardware, determining the installation method, configuring partitions, and selecting packages to install based on the intended use of the system.
This document discusses user and file permissions in Linux. It covers how every file is owned by a user and group, and how file access is defined using file mode bits. These bits determine read, write and execute permissions for the file owner, group and others. An example of a file with permissions -rw-rw-r-- is provided to demonstrate this. User accounts are configured in /etc/passwd, while passwords are securely stored in /etc/shadow. Common commands for managing users, groups, permissions and default file access (umask) are also outlined.
The document discusses subnetting and provides an example of how to subnet the IP network address 192.168.1.128 into 6 subnets. It explains that subnetting allows a single network number to be shared among multiple physical networks. Each host is configured with an IP address and subnet mask, where the subnet is calculated by performing a bitwise AND of the IP address and subnet mask. The example shows how to determine the subnet mask is 255.255.255.224 when creating 6 subnets, and that each subnet can support up to 30 hosts.
The document discusses DHCP and how to configure a DHCP server on Windows Server 2008. DHCP allows automatic assignment of IP addresses and configuration settings to clients on a network. To set up a DHCP server, the DHCP server role is added to a server using the Add Roles Wizard. This presents configuration pages for binding network adapters, setting DNS/WINS options, adding DHCP scopes to define IP address ranges, and authorizing the DHCP server. Key options configured include DNS servers, domain names, and WINS servers to provide additional settings to DHCP clients.
Network File System (NFS) is a distributed file system protocol that allows users to access and share files located on remote computers as if they were local. NFS runs on top of RPC and supports operations like file reads, writes, lookups and locking. It uses a stateless client-server model where clients make requests to NFS servers, which are responsible for file storage and operations. NFS provides mechanisms for file sharing, locking, caching and replication to enable reliable access and performance across a network.
A file server is a computer that centrally stores and manages files so that other computers on a network can access them. It acts as a dedicated system like a network attached storage device to offer fast data access and higher storage capacity than a non-dedicated server. A file server for 250+ users requiring 20TB of storage for files accessed for read, write, and rewrite through fiber-connected switches would need a powerful CPU, large RAM, multiple SAS or SSD disks in a RAID 5 configuration, multiple NICs, and a RAID controller.

Telnet is a protocol that allows administrators to remotely access and manage devices, but it transmits usernames and passwords in clear text, posing a security risk. SSH is a more secure replacement for Telnet, as it encrypts all transmitted data using public key cryptography. Both protocols require a client and server, with Telnet using port 23 and SSH typically using port 22.
The document discusses the Network File System (NFS) protocol. NFS allows users to access and share files located on remote computers as if they were local. It operates using three main layers - the RPC layer for communication, the XDR layer for machine-independent data representation, and the top layer consisting of the mount and NFS protocols. NFS version 4 added features like strong security, compound operations, and internationalization support.

This document summarizes the server configuration and Active Directory setup at a school. It describes the primary and secondary ESXi servers that run domain controllers, file servers, backup servers, and terminal servers. It explains how the domain controllers manage computers and users across different domains, including the staff1, student1, and root ocaat1 domains. It provides instructions for adding user accounts, setting up group policies, configuring the DHCP and DNS servers, and establishing file sharing permissions.
System and network administration network servicesUc Man
Network services like DNS, DHCP, FTP, SMTP, SNMP, proxy servers, and Active Directory Services provide shared resources to devices on a network. DNS in particular converts domain names to IP addresses, caching responses for a period of time specified by their Time to Live (TTL) value to reduce server load. However, DNS was not originally designed with security in mind and is vulnerable to issues like cache poisoning. DHCP automatically assigns temporary IP addresses to devices on a network. Active Directory is a directory service used by Windows domains to centrally manage network resources and user access through objects, sites, forests, trees and domains.
This document discusses user administration in Linux. It describes the different types of user accounts - root, system, and user accounts. The root account has complete control while system accounts are for specific system functions. User accounts provide interactive access for general users. Groups are used to logically group user accounts. The main user administration files are /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow. Basic commands for managing users include useradd, usermod, userdel, groupadd, groupmod, and groupdel. Creating, modifying, and deleting users and groups are demonstrated.
This document provides an overview of common Linux networking commands such as ifconfig, route, traceroute, nslookup, arp, dig, and netstat that are used to configure network interfaces, display routing tables, trace network routes, lookup domain names, manage address resolution, query DNS servers, and view network statistics.

The document discusses the Dynamic Host Configuration Protocol (DHCP). DHCP allows network devices to request and obtain IP addresses and other configuration information automatically from a DHCP server. When a device boots up or connects to the network, it will broadcast a DHCP discover message. A DHCP relay forwards the request to the DHCP server, which will provide an IP address and other configuration parameters to the client through a DHCP offer message. Addresses are leased for a period of time before needing renewal to allow for dynamic allocation and reuse of addresses. This automatic provisioning simplifies network configuration management.
This document provides an overview of Logical Volume Management (LVM) including its core components and functionality. LVM allows for flexible, online storage management through the creation of logical volumes atop physical volumes. It supports resizing storage pools, online data relocation, disk striping, mirroring volumes, and volume snapshots. The key components are physical volumes (PVs), volume groups (VGs), and logical volumes (LVs). PVs can be partitions or entire disks. VGs pool multiple PVs into a single storage space with extents. LVs are then created within VGs with properties like linear, striped, or mirrored layouts. Device mapper provides access to LVs and handles tasks like mirroring and
Term 5 students will have the opportunity to take samba rhythm workshops led by Mags from the Merton Music Foundation and London School of Samba. They will learn about the history and origins of samba music and instruments. The document then provides details on several traditional samba instruments - their origins, what they look like, and how they are played as part of samba ensembles.
Samba originated in Africa and developed in Brazil in the 19th century. It is considered the dance of celebration, especially during Rio's Carnival. There are many variations of Samba dances and music styles. Samba is danced to fast-paced music around 100 beats per minute, encouraging spontaneous street dancing during Carnival celebrations. It has a distinctive footwork pattern of quick, quick, slow steps and features dramatic climaxes where dancers throw their heads back and extend their arms out.

Analytic accounts are used to track and manage financial transactions related to specific projects, departments, or business units. They provide detailed insights into costs and revenues at a granular level, independent of the main accounting system. This helps to better understand profitability, performance, and resource allocation, making it easier to make informed financial decisions and strategic planning.
Exploring Substances:
Acidic, Basic, and
Neutral
Welcome to the fascinating world of acids and bases! Join siblings Ashwin and
Keerthi as they explore the colorful world of substances at their school's
National Science Day fair. Their adventure begins with a mysterious white paper
that reveals hidden messages when sprayed with a special liquid.
In this presentation, we'll discover how different substances can be classified as
acidic, basic, or neutral. We'll explore natural indicators like litmus, red rose
extract, and turmeric that help us identify these substances through color
changes. We'll also learn about neutralization reactions and their applications in
our daily lives.

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder
Introduction
All the materials around us are made up of elements. These elements can be broadly divided into two major groups:
Metals
Non-Metals
Each group has its own unique physical and chemical properties. Let's understand them one by one.
Physical Properties
1. Appearance
Metals: Shiny (lustrous). Example: gold, silver, copper.
Non-metals: Dull appearance (except iodine, which is shiny).
2. Hardness
Metals: Generally hard. Example: iron.
Non-metals: Usually soft (except diamond, a form of carbon, which is very hard).
3. State
Metals: Mostly solids at room temperature (except mercury, which is a liquid).
Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid).
4. Malleability
Metals: Can be hammered into thin sheets (malleable).
Non-metals: Not malleable. They break when hammered (brittle).
5. Ductility
Metals: Can be drawn into wires (ductile).
Non-metals: Not ductile.
6. Conductivity
Metals: Good conductors of heat and electricity.
Non-metals: Poor conductors (except graphite, which is a good conductor).
7. Sonorous Nature
Metals: Produce a ringing sound when struck.
Non-metals: Do not produce sound.
Chemical Properties
1. Reaction with Oxygen
Metals react with oxygen to form metal oxides.
These metal oxides are usually basic.
Non-metals react with oxygen to form non-metallic oxides.
These oxides are usually acidic.
2. Reaction with Water
Metals:
Some react vigorously (e.g., sodium).
Some react slowly (e.g., iron).
Some do not react at all (e.g., gold, silver).
Non-metals: Generally do not react with water.
3. Reaction with Acids
Metals react with acids to produce salt and hydrogen gas.
Non-metals: Do not react with acids.
4. Reaction with Bases
Some non-metals react with bases to form salts, but this is rare.
Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc).
Displacement Reaction
More reactive metals can displace less reactive metals from their salt solutions.
Uses of Metals
Iron: Making machines, tools, and buildings.
Aluminum: Used in aircraft, utensils.
Copper: Electrical wires.
Gold and Silver: Jewelry.
Zinc: Coating iron to prevent rusting (galvanization).
Uses of Non-Metals
Oxygen: Breathing.
Nitrogen: Fertilizers.
Chlorine: Water purification.
Carbon: Fuel (coal), steel-making (coke).
Iodine: Medicines.
Alloys
An alloy is a mixture of metals or a metal with a non-metal.
Alloys have improved properties like strength, resistance to rusting.

2. At a glance Samba
• What is Samba
• Why we use Samba
• Configuration file name
• Configuring a Samba Server
• Connecting to a Samba Share
Command Line
Graphical
• Mounting the Share
• Troubleshooting Samba
• Useful Websites
3. What is Samba
• Samba is a popular freeware program that allows end users to access
and use files, printers, and other commonly shared resources on a
company's intranet or on the Internet. Samba is often referred to as a
network file system and can be installed on a variety of operating
system platforms, including: Linux, most common UNIX platforms,
OpenVMS, and OS/2.
• Samba uses the SMB protocol to share files and printers across a
network connection
4. Why we use Samba
A Samba server offers the following services:
• Samba is useful if you have a network of both Windows and Linux
machines
• Samba is a strong network service for file and print sharing
• Samba is reliable software that runs on reliable Unix operating system
• Samba has a very nice cost advantage: it's free.
• Share one or more Distributed filesystem (Dfs) trees
• Authenticate clients logging onto a Windows domain
5. Configuration file name
• Configuration file name is smb.conf that’s are /etc/samba/smb.conf
• We also need to know about this
smbd--- The smbd daemon provides the file and print services to SMB
clients
Nmbd--- The nmbd daemon provides NetBIOS nameservice and
browsing support
Smbclient--The smbclient program implements a simple ftp-like client.
Testparm-- The testparm utility is a simple syntax checker for Samba's
Smbstatus-- The smbstatus tool provides access to information about
the current connections
smbcaclsThe smbcacls command is a tool to set ACL's on remote CIFS
servers
6. Configuring a Samba Server
• Samba has provided secure, stable and fast file and print services for all
clients using the SMB/CIFS protocol,
• Package name”samba4” now its install use to yum server
# yum install samba4*,,,,, Configure firewall to allow smb traffic
Port number 137,138,139,445 allow this port tcp &udp
Example- iptables -I INPUT -p tcp --dport 138 -j ACCEPT
iptables -I INPUT -p udp --dport 137 -j ACCEPT
Now save iptables “# service iptables save” and “# service iptables restart”
• create directories which you want to share or use existing directory
#mkdir share and create some file on this directory--# touch file1 file2 file3
• create a user to access smb share or use existing user
7. # useradd us1,,,,,,,,# passwd us1 [passwd add]
# smbpasswd -a us1 [ if you use existing user then only this command would be
enough]
Now go to # vim /etc/samba/smb.conf then go to # find the line starts with
"workgroup=mygroup"change the mygroup to WORKGROUP
fine the line starts with "host allow=“
remove the semicolon (;) and modify the line to add the networks you want to
give access to
Now go to the last line of the file and insert a new line
• [sharename]
• comment = any comment
• path = /path-of-the-share-directory
• browseable = yes
• writable = yes
• printable = yes
• valid users = username
8. For every share you have to cofigure this file again and again
Now run this command
# service smb start
# chkconfig smb on
# service nmb start
# chkconfig nmb on
# service winbind start
# chkconfig winbind on
To check the share
• smbclient -L ip -U username
• type the password of the user and you should see the shares
9. Client Configure
• You don't need to configure any client to use smb.
• smb-client package is installed by default.
• To view the shares of a machine type
• smbclient -L ip-or-hostname -U username
• Example: smbclient -L 192.168.100.254 -U student
10. Connecting to a Samba Share
• You can use Nautilus to view available Samba shares on your network
• Command Line( smbclient -L ip-or-hostname -U username)
• Mounting the Share
11. Mounting the Share
• To mount a samba share
• mount.cifs //target/sharename /mounting_directory -o user=username
• Example: mount.cifs //192.168.100.254/share /mountsmb -o user=student
• [assuming that the target server is 192.168.100.254, the sharename is
share,
• the mounting directory is /mountsmb and the user is student]
• enter the password for the user student
• ls /mountsmb
• you should see the contents of the share in the /mountsmb directory.
12. Troubleshooting Samba
• In addition to checking for spelling and typographical errors, check to
ensure the Linux firewall is permitting Samba traffic. Similarly, if
you're using SELinux on your system, you must explicitly permit
Samba traffic, and finally you must enable Network Discovery on the
Windows client machine.
