1) Plan a network topology with a server, gateway, and client devices.
2) Perform subnetting calculations to divide IP addresses into public and private networks.
3) Assemble and install a Debian server, configure networking and services like DHCP, Apache, and Squid proxy server.
4) Configure the router and firewall rules for network address translation and proxy access.
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. It also discusses how to use ifconfig to assign IP addresses to interfaces, route to view routing tables, arp to manage the address resolution cache, and dig for more powerful DNS lookups than nslookup.
The document describes how to configure a Linux machine as a router to connect two subnets. It provides instructions to enable IP forwarding and configure the network interfaces using temporary and permanent methods.
The summary is:
- Enable IP forwarding and configure the network interfaces of two Ethernet cards using ifconfig to set up routing temporarily
- Use netconf to configure the interfaces and routing permanently by editing settings, accepting changes, and rebooting to confirm the configuration persists
- Install traffic generator programs on end stations to test routing of UDP and TCP packets between subnets going through the router
The document discusses various Linux network configuration and troubleshooting commands, including ifconfig for configuring network interfaces and viewing network settings, ping for testing network connectivity, traceroute for tracing the network route to a destination, and commands like netstat, dig, nslookup, route, host, arp, ethtool, iwconfig, and hostname for additional network tasks and information retrieval. It provides examples and brief explanations of how to use each command.
Upon reading the document, the key steps in a router's start-up process can be summarized as follows:
1. When power is applied, the router performs a power-on self-test and loads the bootstrap code from ROM to initialize hardware and find the IOS image.
2. The IOS image is then loaded from flash memory or another source such as TFTP into RAM where it is decompressed and executed.
3. The startup configuration is loaded, typically from NVRAM. If no configuration is present, the router enters setup mode to configure initial settings.
This document provides an overview of various networking tools in Linux, including commands for network configuration (ifconfig, route), connectivity testing (ping, traceroute), name resolution (host, nslookup), port and protocol inspection (netstat, tcpdump), and secure remote access (SSH, PuTTY).

How to access the Netapp cluster mode 8.2 through CLI (command mode)Saroj Sahu
This document provides 3 methods for accessing a NetApp cluster mode storage system through the command line interface (CLI).
Method 1 involves connecting a laptop directly to the storage system's serial port using PuTTY software and logging in with username "admin". Method 2 allows using telnet or RSH by first cloning the firewall policy and enabling those services, but they are insecure. Method 3, which is recommended, uses SSH to securely access the storage system by hostname or IP and log in as "admin". The document provides instructions for downloading PuTTY and checking which CLI services are enabled or disabled.

How to see the event and audit logs through ( gui and cli) in cluster ontap n...Saroj Sahu
With the help of this document, we can check the logs in NetApp storage. It will very helpful for troubleshooting of the issues. we can easily take the decision to act on the current issue by analysing the logs.
NetApp snapshot technology works by preserving the inode map at the time a snapshot is created and continuing to change the inode map on the active file system, while keeping the older version for the snapshot. Snapshots can be created quickly in just a few seconds without impacting performance and up to 255 snapshots can be created per volume, providing point-in-time copies of data.
High availability ensures that network services and data are accessible at all times by configuring storage systems in high availability pairs. When a network interface fails, negotiated failover can trigger an automatic failover of the storage system to prevent loss of connectivity. Enabling negotiated failover and selecting which network interfaces to include allows the storage system to fail over to the other node. The benefits of high availability include uninterrupted data access, and the ability to perform nondisruptive upgrades to storage system components like motherboards, adapters, disks and interfaces.
3PAR: HOW TO CHANGE THE IP ADDRESS OF HP 3PAR SANSaroj Sahu
The document provides steps to change the IP address of a HP 3PAR SAN. It outlines logging into the SAN through Putty using default credentials. It then details using the 'setnet' command to change the IP address, netmask, and gateway. The 'shownet' command confirms the new network settings. Login to the SP console allows changing additional settings like the hostname through interactive menus.
Aggregate standard for Netapp storage 7 mode Saroj Sahu
1. Storage teams create aggregates using naming conventions like aggr0, aggr1 to provision storage. They decide the configuration including the RAID type, number of disks, and disk size.
2. When creating an aggregate, factors like recovery speed, data assurance, and storage space must be considered. Larger RAID groups improve performance but increase risk of data loss if multiple disks fail, while smaller groups reduce this risk but decrease performance.
3. Guidelines for RAID group sizing depend on disk type, with ATA/SATA generally having smaller groups than FC/SAS. The default sizes balance speed, protection, and space utilization, though the maximum sizes allow flexibility based on needs.
