How to increase the swap space on Centos7

2020-10-15T11:34:00.004-05:00

In below command as you guys can see there is two hard disk onek is /dev/sda another one is /dev/sdb. Into the second hard dsik we are going to create a space 4Gigabyte for swap

[root@centos7 ~]# fdisk -l

Disk /dev/sdb: 10.7 GB, 10737418240 bytes, 20971520 sectors

Units = sectors of 1 * 512 = 512 bytes

[root@centos7 ~]#

Now we are going to create a space for swap. As you can see in the below command, I have used 2 primary partition and 2 is still free. So that is why we are going to create the partition into primary. If you guys see that your primary partition is been used than you can go for extended partition.

[root@centos7 ~]# fdisk /dev/sdb

Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

How to use mounting an existing CD-ROM image under Sun Solaris

2020-02-17T21:26:00.002-06:00

bash-3.2# lofiadm -a /eis-dvd-Dec2013.iso /dev/lofi/1

bash-3.2# mount -F hsfs -o ro /dev/lofi/1 /mnt

Mounting an Existing ISO CD-ROM Image under Solaris UNIX:

If your image name is cd.iso, you can type command:

# lofiadm -a /path/to/cd.iso

Output:

/dev/lofi/1

Please note that the file name argument on lofiadm must be fully qualified and the path must be absolute not relative.

/dev/lofi/1 is the device; use the same to mount iso image with mount command:

# mount -o ro -F hsfs /dev/lofi/1 /mnt

# cd /mnt

# ls -l

# df -k /mnt

Mount the loopback device as a randomly accessible file system with

mount -F hsfs -o ro /dev/lofi/X /mnt.

Alternatively, use this combined format:

mount -F hsfs -o ro `lofiadm -a /path/to/image.iso` /mnt

Unmount and detach the images:

Use umount command to unmount image:

# umount /mnt

Now remove/free block device:

# lofiadm -d /dev/lofi/1

For more information read lofiadm and lofi man pages by typing the following command:

# man lofiadm

# pkg set-publisher –g file:///media/SOL11REPO_FULL/repo \ solaris
2. Set up GUI OS mode(GNOME) from text mode.
# pkg install slim_install

3. Activate GDM(GNOME Desktop Manager) Using SMF
# svcs –a | grep gdm (check gdm service is disabled)
# svcadm enable gdm (enable gdm service)
# svcs –a | grep gdm (check gdm service is enable)
automatically start GNOME GUI
or
Temperately Manual-start GNOME GUI

Configuration of Samba

1. First, we need to create a Samba directory, where all the shared data will be stored.

[root@node1 ~]# mkdir /sambadir

[root@node1 ~]# ls -ldZ /sambadir/

drwxr-xr-x. root root unconfined_u:object_r:default_t:s0 /sambadir/

[root@node1 ~]# semanage fcontext -a -t samba_share_t "/sambadir(/.*)?"

[root@node1 ~]# restorecon -Rv /sambadir/

[root@node1 ~]# ls -ldZ /sambadir/

drwxr-xr-x. root root unconfined_u:object_r:samba_share_t:s0 /sambadir/

[root@node1 ~]#

2. Make a backup of the configuration file by copying it in the same or another directory.

[root@node1 ~]# cp /etc/samba/

lmhosts smb.conf smb.conf.example

[root@node1 ~]# cp /etc/samba/smb.conf /etc/samba/smb.conf.back

Setting up Samba User Account

[root@node1 /]# useradd node2

[root@node1 /]# smbpasswd -a node2

New SMB password:

Retype new SMB password:

Added user node2.

Configuring Samba Shares

Now we will configure the directory samba as a share that we have created. For this, we will have to add the following lines in the Samba configuration file.

Add the following line to the bottom of the smb.conf file.

[root@node1 ~]#vi /etc/samba/smb.conf

[samba_share_t]

comment = Sambadir share

path = /sambadir

read only = no

browsable = yes

Restart Samba Service

[root@node1 ~]# systemctl restart smb

Connecting Samba Share

Connecting from Linux

There are two ways to connect Samba share from Linux client.

1. Using Command Line

2. Using GUI

1. Using the command line

To connect Samba share through the Linux command line, we need a smbclient tool. We need to install smbclient tool to the server

[root@node1 ~]# yum install samba-client

Once the installation is completed, run the command by using the following syntax to access Samba share

[root@node2 ~]# smbclient //node1/samba_share_t -U node2

Enter SAMBA\node2's password:

Try "help" to get a list of possible commands.

smb: \>

2. Using GUI

To access Samba share via GUI, open Linux File Manager. Click on Connect to Server and write down the below command.

smbclient //node1/samba_share_t

Network Basics ( Information of OSI model and others)

2017-11-24T09:16:00.001-06:00

OSI & TCP/IP models

OSI model

OSI (Open Systems Interconnection) model was created by the International Organization for Standardization (ISO), an international standard-setting body. It was designed to be a reference model for describing the functions of a communication system. It has seven layers, with each layer describing a different function of data traveling through a network.

Here is the graphical representation of these layers:

Application
Presentation
Session
Transport
Network
Datalink
Physical

The layers are usually numbered from the last one, meaning that the Physical layer is consider to be the first layer. It is good to learn these layers, since there will certainly be a couple of questions on the CCNA exam regarding them. Most people learn the mnemonic "Please Do Not Throw Sausage Pizza Away":

Application---- Away
Presentation--- Pizza
Session--- Sausage
Transport---Throw
Network---Not
Datalink---Do
Physical---Please

So, what is the purpose of these layers?
They are most commonly used by vendors. They enable them to implement some

functionality into a networking device, which then enables easier interoperability with devices from other vendors.

Here is a brief description of each of these layers.

Physical – defines how to move bits from one device to another. It details how cables, connectors and network interface cards are going to work and how to send and receive bits.

Data Link – encapsulates a packet in a frame. A frame contains a header and a trailer that enable devices to communicate. A header, most commonly, contains a source and a destination MAC address. A trailer contains the Frame Check Sequence field, which is used to detect transmission errors.

The data link layer has two sublayers:

1. Logical Link Control – used for flow control and error detection
2. Media Access Control – used for hardware addressing and controlling the access method

Network – defines device addressing, routing, and path determination. Device (logical) addressing is used to identify a host on a network (e.g. by its IP address).

Transport – segments great chunks of data received from the upper layer protocols. Establishes and terminates connections between two computers. Used for flow control and data recovery.

Session – defines how to establish and terminate a session between the two systems.

Presentation – defines data formats. Compression and encryption are defined at this layer.

Application – this layer is the closest to the user. It enables network applications to communicate with other network applications.

TCP/IP model

The TCP/IP model was created in the 1970s by the Defense Advance Research Project Agency (DARPA). Like the OSI model, it describes general guidelines for designing and implementing computer protocols.
It consists of four layers: Network Access, Internet, Transport, and Application.

As you can see, the TCP/IP model has fewer layers than the OSI model. The Application, Presentation, and Session layers of the OSI model are merged in only one layer, Application layer, in the TCP/IP model. Also, Physical and Data Link layers are called Network Access layer in the TCP/IP model.

Differences between OSI and TCP/IP model

There are some other differences between these two models, besides the obvious difference in the number of layers. OSI model prescribes the steps needed to transfer data over a network and it is very specific in it, defining which protocol is used at each layer and how. The TCP/IP model is not that specific. It can be said that the OSI model prescribes and TCP/IP model describes

Encapsulation

The term “encapsulation” is used to describe a process of adding headers and trailers around some data. For example, when you send an email using your favourite email program (like Outlook or Thunderbird) that email is sent from the Application layer to the Transport layer. The Transport layer encapsulates the data and adds its own header (with its own information, such as which port will be used) and passes the data to the Internet layer, which again encapsulates the received data and adds its own header, usually with information about the source and destination IP addresses. The Internet layer than passes the data to the Network Access layer. This layer is the only layer that adds both a header and a trailer. The data is then sent through a physical network link.

Each layer adds its own information:

The term “decapsulation” refers to the process of removing headers and trailers as data passes from lower to upper layers. This process happens on a computer that is receiving data.

Frame, packet, segment

Frame – the term “frame” refers to the encapsulated data defined by the Network Access layer. A frame can have a header and a trailer that encapsulate a data section.

Packet – the term “packet” is used to describe the encapsulated data defined by the Internet layer. A packet can have a header with the source and destination IP addresses.

Segment – the term “segment” describes encapsulated data defined by the Transport layer. A segment can have a header with informations such as source and destionation port numbers, sequence and acknowledgment numbers, etc.

Ethernet is the most used networking technology for LANs today. It defines wiring and signaling for the Physical layer of the OSI model. For the Data Link layer, it defines frame formats and protocols.

Ethernet is described as IEEE 802.3 standard. It uses Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method and supports speeds up to 100 Gbps. It can use coaxial, twisted pair and fiber optic cables. Ethernet uses frames to with source and destination MAC addresses to deliver data

Ethernet frame

We have already learned that encapsulated data defined by the Network Access layer is called an Ethernet frame. An Ethernet frame starts with a header, which contains the source and destination MAC addresses, among other data. The middle part of the frame is the actual data. The frame ends with a field called Frame Check Sequence (FCS).

The Ethernet frame structure is defined in the IEEE 802.3 standard. Here is a graphical representation of an Ethernet frame and a description of each field in the frame:

· Preamble – informs the receiving system that a frame is starting and enables synchronisation.

· SFD (Start Frame Delimiter) – signifies that the Destination MAC Address field begins with the next byte.

· Destination MAC – identifies the receiving system.

· Source MAC – identifies the sending system.

· Type – defines the type of protocol inside the frame, for example IPv4 or IPv6.

· Data and Pad – contains the payload data. Padding data is added to meet the minimum length requirement for this field (46 bytes).

· FCS (Frame Check Sequence) – contains a 32-bit Cyclic Redundancy Check (CRC) which allows detection of corrupted data.

MAC & IP addresses

MAC address
A Media Access Control (MAC) address is a 48-bit address that is used for communication between two hosts in an Ethernet environment. It is a hardware address, which means that it is stored in the firmware of the network card.
A MAC address is supposed to be globaly unique. Each network card vendor gets its share of addresses (represented by the first 24 bits).
D8-D3-85-EB-12-E3

Every hexadecimal character represents 4 bits, so the first six hexadecimal characters represent the vendor (in this case, Hewlett Packard).
How to find out your own MAC address?

If you are using Windows, enter the Command Prompt (Start – Programs – Accessories – Command Prompt). Type the ipconfig/all command and you should see a field called Physical address under the Ethernet adapter settings:

If you are using Linux, type the ifconfig command. You should see your MAC address referred to as HWaddress.

IP address

An IP address is a 32-bit number that identifies a host on a network. It is usually written in the form of four decimal numbers seperated by periods (e.g. 10.0.50.1).

In contrast to MAC address, an IP address is a logical address. Any device that wants to communicate with other device using TCP/IP needs to have an IP address. It can be configured manually or it can be obtained from a DHCP server.

The term “IP address” is usually used for IPv4, which is the fourth version of the IP protocol. A newer version exists, IPv6, and uses 128-bit addressing.

Private IP addresses
There are three ranges of addresses that can be used in a private network (e.g. your home LAN). These addresses are not routable through the Internet.

Private addresses ranges:

10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255

How to find out your IP address
Windows users:
Enter the Command Promt (Start – Programs – Accessories – Command Prompt).

Linux users:

Enter ifconfig. You should see a field called inet addr:

Unicast, multicast, and broadcast addresses

There are three types of Ethernet addresses:

· unicast addresses – represent a single LAN interface. A unicast frame will be sent to a specific device, not to a group of devices on the LAN.

· multicast addresses – represent a group of devices in a LAN. A frame sent to a multicast address will be forwarded to a group of devices on the LAN.

· broadcast addresses – represent all device on the LAN. Frames sent to a broadcast address will be delivered to all devices on the LAN.

The broadcast address has the value of FFFF.FFFF.FFFF (all binary ones). The switch will flood broadcast frames out all ports except the port that it was received on.

Multicast frames have a value of 1 in the least-significant bit of the first octet of the destination address. This helps a network switch to distinguish between unicast and multicast addresses. One example of an Ethernet multicast address would be 01:00:0C:CC:CC:CC, which is an address used by CDP (Cisco Discovery Protocol).

Network devices

Hubs

A hub serves as a central point to which all of the hosts in a network connect to. It is an OSI layer 1 device. It receives a signal from one port and sends it out to all other ports. Sometimes it is called a multiport repeater (photo credit: Wikipedia)

Today, these devices are considered obsolete and switches are commonly used instead. Hubs have numerous disadvantages. They are not aware of the traffic that passes through them. They create only one large collision domain. A hub typically operates in half duplex. There is also a security issue with hubs since the traffic is forwarded to all ports (except the source port), which makes it possible to capture all traffic on a network with a network sniffer!

Switches

Like hubs, a switch is used to connect multiple hosts together, but it has many advantages over a hub. Switch is an OSI Layer 2 device, which means that it can inspect received traffic and make forwarding decisions. Each port on a switch is a separate collision domain and can run in a full duplex mode (photo credit: Wikipedia).

How switches work

Let’s take a look at the following example:

Host A is trying to communicate with Host B and sends a packet. A packet arrives at the switch, which looks at the destination MAC address. The switch then searches that address in its MAC address table. If the MAC address is found, the switch then forwards the packet only to the port that connected to the frame’s destination. If the MAC address is not found, the switch will flood the frame out all other ports. To learn which MAC address is associated with which port, switches examine the source MAC addresses of the receiving packet and store that MAC addresses in their MAC address table.

What is a MAC address table?

A MAC address table lists which MAC address is connected to which port. It is used by switches to make forwarding decisions. The table is populated by examining the source MAC address of the incoming packet. If the source MAC address of a packet is not present in the table, the switch adds an entry to it’s MAC address table.

Difference between a switch and a bridge

A switch is sometimes called a multiport bridge, but there are differences between these two devices. A bridge usually has fewer ports than switch. A switch operates faster because it is hardware-based, which means that it uses chips (ASICs) when making forwarding decisions. In contrast, a bridge is software based. A switch can also have multiple spanning-tree instances while a bridge can have only one. Switches can also have multiple broadcast domains, one per VLAN.

Routers

A router is a device that routes packets from one network to another. A router is most commonly an OSI Layer 3 device. Routers divide broadcast domains and have traffic filtering capabilities.

The picture below shows a typical home router:

How routers work

A router uses IP addresses to figure out where to send packets. If two hosts from different networks want to communicate, they will need a router between them to route packets

For example, check the following scenario:

Host A and host B are on different networks. If host A wants to communicate with host B, it will have to send a packet to the router. The router receives the packet and checks the destination IP address. If the destination IP address is in the routing table, the router will forward the packet out the interface associated with that network.

What is a routing table?

A routing table lists a route for every network that a router can reach. It can be statically configured (using IOS commands) or dynamically learned (using a routing protocol). It is used by routers when deciding where to forward packets.

The command to display an IP routing table is show ip route. In the picture above, you can see that this router has two directly connected subnets. Let’s take a closer look at the first entry in the routing table:

„C“ means that the route is a directly connected route. The network in question is 10.0.0.0/8, and the router will forward each packet destined for that network out interface FastEthernet0/1.

NOTE – in Windows, you can use the netstat –r command to display the routing table of your system.

Half duplex and full duplex

In telecommunication, a duplex communication system is a point-to-point system of two devices that can communicate with each other in both direction. These two types of duplex communication systems exist in Ethernet environments:

· half-duplex – a port can send data only when it is not receiving data. In other words, it cannot send and receive data at the same time. Network hubs run in half-duplex mode in order to prevent collisions. Since hubs are rare in modern LANs, the half-duplex system is not widely used in Ethernet networks anymore.

· full-duplex – all nodes can send and receive on their port at the same time. There are no collisions in full-duplex mode, but the host NIC and the switch port must support the full-duplex mode. Full-duplex Ethernet uses two pairs of wires at the same time instead of a single wire pair like half-duplex.

NOTE – each NIC and switch port has a duplex setting. For all links between hosts and switches, or between switches, the full-duplex mode should be used. However, for all links connected to a LAN hub, the half-duplex mode should be used in order to prevent a duplex mismatch that could decrease network performance.

IEEE Ethernet standards

Ethernet is defined in a number of IEEE (Institute of Electrical and Electronics Engineers) 802.3 standards. These standards define the physical and data-link layer specifications for Ethernet. The most important 802.3 standards are:

· 10Base-T (IEEE 802.3) – 10 Mbps with category 3 unshielded twisted pair (UTP) wiring, up to 100 meters long.

· 100Base-TX (IEEE 802.3u) – known as Fast Ethernet, uses category 5, 5E, or 6 UTP wiring, up to 100 meters long.

· 100Base-FX (IEEE 802.3u) – a version of Fast Ethernet that uses multi-mode optical fiber. Up to 412 meters long.

· 1000Base-CX (IEEE 802.3z) – uses copper twisted-pair cabling. Up to 25 meters long.

· 1000Base-T (IEEE 802.3ab) – Gigabit Ethernet that uses Category 5 UTP wiring. Up to 100 meters long.

· 1000Base-SX (IEEE 802.3z) – 1 Gigabit Ethernet running over multimode fiber-optic cable.

· 1000Base-LX (IEEE 802.3z) – 1 Gigabit Ethernet running over single-mode fiber.

· 10GBase-T (802.3.an) – 10 Gbps connections over category 5e, 6, and 7 UTP cables.

Notice how the first number in the name of the standard represents the speed of the network in megabits per second. The word base refers to baseband, meaning that the signals are transmitted without modulation. The last part of the standard name refers to the cabling used to carry signals. For example, 1000Base-T means that the speed of the network is up to 1000 Mbps, baseband signaling is used, and the twisted-pair cabling will be used (T stands for twisted-pair).

Cisco three-layer hierarchical model

Because networks can be extremely complicated, with multiple protocols and diverse technologies, Cisco has developed a layered hierarchical model for designing a reliable network infrastructure. This three-layer model helps you design, implement, and maintain a scalable, reliable, and cost-effective network. Each of layers has its own features and functionality, which reduces network complexity.

Here is a description of each layer:

· Access – controls user and workgroup access to the resources on the network. This layer usually incorporates Layer 2 switches and access points that provide connectivity between workstations and servers. You can manage access control and policy, create separate collision domains, and implement port security at this layer.

· Distribution – serves as the communication point between the access layer and the core. Its primary functions is to provide routing, filtering, and WAN access and to determine how packets can access the core. This layer determines the fastest way that network service requests are accessed – for example, how a file request is forwarded to a server – and, if necessary, forwards the request to the core layer. This layer usually consists of routers and multilayer switches.

· Core – also referred to as the network backbone, this layer is responsible for transporting large amounts of traffic quickly. The core layer provides interconnectivity between distribution layer devices it usually consists of high speed devices, like high end routers and switches with redundant links.
