Networking Tools
✅ What are Networking Tools?
Networking tools are software applications or hardware devices used by IT professionals to analyze, troubleshoot, secure, and manage network connections and devices. These tools help ensure networks are running efficiently and securely.
🔑 Types of Networking Tools & Their Functions:
Troubleshooting & Diagnostics
Identify and solve network issues
Ping, Traceroute, Nslookup, Netstat
Network Monitoring
Monitor network performance and traffic
Wireshark, PRTG, Zabbix, Nagios
Bandwidth & Traffic Analysis
Analyze network usage and data flow
SolarWinds, ntopng, NetFlow Analyzer
Security & Vulnerability
Detect and prevent threats, check for vulnerabilities
Nmap, Nessus, OpenVAS, Snort
IP Address Management (IPAM)
Manage IP addresses, DHCP, DNS
Infoblox, BlueCat, phpIPAM
Remote Access & Control
Remotely access and manage devices
PuTTY, Remote Desktop, TeamViewer, AnyDesk
Packet Analysis
Inspect and analyze packets flowing in the network
Wireshark, Tcpdump
🌐 Common Networking Tools & Commands (Details):
1. Ping
Purpose: Check if a host is reachable and measure round-trip time.
Command:
cssCopyEditping [hostname/IP]Example:
nginxCopyEditping google.com2. Traceroute (Windows: tracert)
Purpose: Trace the path packets take to reach a destination.
Command:
scssCopyEdittraceroute [hostname/IP] (Linux/Mac)
tracert [hostname/IP] (Windows)3. IPconfig / Ifconfig
Purpose: View and manage IP address configurations.
Windows:
bashCopyEditipconfig /allLinux/Mac:
nginxCopyEditifconfig4. Nslookup / Dig
Purpose: Query DNS records.
Commands:
nginxCopyEditnslookup google.com
dig google.com5. Netstat
Purpose: View network connections, routing tables, interface stats.
Command:
nginxCopyEditnetstat -an6. Wireshark (Graphical Packet Analyzer)
Purpose: Capture and analyze packets in real-time.
Usage: Deep inspection of traffic for troubleshooting and security.
7. Nmap (Network Mapper)
Purpose: Network discovery and security auditing (port scanning, detecting services).
Command:
cssCopyEditnmap [target IP or hostname]8. PuTTY (SSH Client)
Purpose: Secure remote access to devices using SSH/Telnet.
9. Tcpdump (Command-line Packet Sniffer)
Purpose: Capture packets and analyze them from terminal/CLI.
Command:
cssCopyEdittcpdump -i eth010. Netcat (nc)
Purpose: Read and write data across networks, useful for testing and debugging.
Command:
cssCopyEditnc [options] [hostname] [port]🖥️ Graphical Tools & Software:
