    Study Notes

    Command Line Network Utilities

    • Command line utilities are used for network troubleshooting
    • They run from a command line interface, not the operating system's graphical interface
    • They can be used on both Windows and Linux operating systems

    ipconfig/ip

    • ipconfig in Windows and ip in Linux show the current IP address, subnet mask, default gateway
    • The ip command in Linux replaced the deprecated ifconfig command

    Hostname

    • hostname in Windows shows the device name
    • The hostname command in Linux can change the name, view the system domain and show the IP address.

    Ping

    • ping is used to test connectivity between two devices by sending an ICMP packet
    • If there's a response, the device is connected and active
    • If there's no response, the device is offline

    Tracert/Traceroute

    • tracert in Windows and traceroute in Linux show the path a packet takes to the destination
    • Each device the packet travels through is a hop
    • Linux defaults to sending UDP packets, Windows uses ICMP packets

    Pathping

    • Pathping in Windows combines the Ping and Tracert utilities
    • It checks connectivity, shows latency and packet loss per hop

    netstat

    • netstat shows network-related statistics
    • It provides a snapshot of TCP connections, connected ports, programs using connections
    • This information can be used to monitor traffic and identify unwanted connections

    nslookup and dig

    • DNS (Domain Name System) associates IP addresses with website or computer names
    • Improperly configured DNS leads to connectivity issues
    • nslookup in Windows and dig in Linux view and modify DNS settings

    net

    • net is a Windows command that requires an accompanying command
    • net user allows adding, removing, or modifying local computer accounts
    • net use modifies connections to shared network resources

    Chkdsk

    • Chkdsk in Windows scans the hard drive for errors, including bad sectors
    • It attempts to repair any errors
    • Errors on a hard drive can lead to problems with network resources

    Summary

    • Many operating systems have GUI interfaces for network troubleshooting but command line utilities offer more power and options
    • They can be used to create scripts to automate common tasks
