DHCP is a network protocol that assigns IP addresses to devices. DHCP option 42 is the NTP server option, while DHCP option 40 is the NIS domain option.

• DHCP is a protocol used to automatically assign IP addresses to devices on a network.

• DHCP option 42 is used to specify the Network Time Protocol (NTP) server that the client should use.

• DHCP option 40 is used to specify the Network Information Service (NIS) domain that the client should use.

Radius protocol is used for authentication, authorization, and accounting in network communication.

• Radius protocol is used to authenticate users before granting access to a network.

• It also authorizes users based on their credentials and permissions.

• Radius protocol provides accounting functionality to track and monitor user activity on the network.

• It is commonly used in enterprise networks, VPNs, and wireless networks.

• Each VLAN operates as a separate network, allowing for better network management and security.

• VLANs can be created based on different criteria such as department, function, or location.

• For example, a company may create VLANs for finance, marketing, and IT depar...read more

Top 10 basic Linux commands for monitoring

• top - display system processes

• htop - interactive process viewer

• free - display memory usage

• df - display disk usage

• du - display directory space usage

• netstat - display network connections

• ss - another tool to display network connections

• ps - display process status

• tail - display the last few lines of a file

LVM (Logical Volume Manager) is a tool used to manage disk space by creating logical volumes from physical volumes.

• LVM allows for dynamic resizing of logical volumes without the need to unmount the filesystem

• To extend a logical volume, use the 'lvextend' command followed by the size to extend by and the logical volume name

• For example, to extend a logical volume named 'lv_data' by 100MB, the command would be 'lvextend -L +100M /dev/vg_data/lv_data'

rpm is a package manager for Red Hat-based systems, while yum is a high-level package manager that uses rpm as its backend.

• rpm is a low-level package manager that directly interacts with the system's package database and files

• yum is a high-level package manager that automates the process of dependency resolution and package installation

• yum can also automatically download and install dependencies for a package, while rpm does not have this capability

Patching is the process of applying updates or fixes to software to improve security, fix bugs, or add new features.

• Patching involves applying updates or fixes to software to address security vulnerabilities.

• It can also be used to fix bugs or improve performance.

• Patching is important to keep software up to date and secure.

• Examples of patching include installing security updates on a Linux server or updating software on a computer to the latest version.

Replication is the process of creating and maintaining copies of data in multiple locations for redundancy and disaster recovery purposes.

• Replication involves copying data from one location to another in real-time or near real-time

• It helps in ensuring data availability and integrity in case of hardware failures or disasters

• There are different types of replication such as synchronous, asynchronous, and snapshot replication

• Examples include database replication for high availabi...read more

There are different types of replication, including synchronous, asynchronous, and snapshot replication.

• Synchronous replication ensures that data is replicated to multiple locations simultaneously, providing real-time data protection.

• Asynchronous replication allows for a delay between data being written to the primary storage and being replicated to secondary storage.

• Snapshot replication creates point-in-time copies of data for backup and recovery purposes.
