 Bridge: the bridge is layer 2 devices or software connecting different segments(media independent) from one logical segment(single broadcast domain). although the network segments belong to different mediums (wire and wireless). Example: we have logical network 192.168.1.0/24                    Take two hosts with physical networks eth0 and eth1 which belong to the same subnet(Broadcast domain). OR                  eth0 IP :  192.168.1.2 (physical NIC Host-a) and  eth1 IP:   192.168.1.3 (host A-NIC)                     eth0 IP :  192.168.1.2 (physical NIC) and  enp0s3 IP:   192.168.1.3 (vNIC) OR                  eth0 IP:   192.168.1.2 (physical NIC) and wlan0 IP:   192.168.1.3 (wifi NIC) ...

 There is Step by Step procedure to create a partition manually. 1. Take Raw Hard disk The hard disk is without partition and formatting there is nothing on it. 2. Create Partitions(MBR or GPT) what is a partition : it is a logical division of the whole raw hard disk. Three types of partition in the MBR partition system. Primary partition (we have a limit to creating 4 partitions only) Extended partition (when we need more than 4 partitions we create one extended partition) Logical partition (we can create multiple partitions in extended a partition) Note:  Extended Partition is not bootable and also one extended partition per hard disk which is not directly formatted but uses the logical partition. 3. Create Volume After formatting with File System and Assige the Letter we can use the partition.  

SSH Protocol is used in Serval Services as Demone. what is Demone? The daemon is a Background process that runs in a system without user interaction. The program file of the daemon is end with the letter d usually in Linux/Unix-based systems. Note: Process is the Program that is run in the Memory(RAM) for example, HTTP Service uses httpd as a daemon program SSH Service uses sshd .    /etc/init.d/sshd keypair SFTP SCP rsync X11 Forwarding etc......

What is  SSH?    Secure Shell for Any System It is a Secure Shell used to execute commands on the Remote system. Normally we use a command prompt or Shell on the local computer. I have a windows 10 machine we can do ping , ipconfig ,tracetr ....etc. the command for daily troubleshooting in my lab from a local pc but I have another system that contains Linux ubuntu. I went and use its shell or command line interface so we have two ways either use RDP and access the terminal or the 2nd way I installed SSH on it(Linux Machine other than my pc) and access it.   The  SSH has two Components (Both for any machine) 1-SSH Client. 2-SSH Server SSH Client used for access SSH Server for example my pc what to access Linux machine. My PC has only SSH Client (SSH is not installed on my pc) I installed Terminus (as a windows command line terminal)on my windows 10 Machine. SSH Client  instlled by issue the command  ssh. shown in blow image. i am also installed SS...
