What diagnostic utilities are there for TCP/IP?

A. We have already seen PING and TRACERT, and below is a full list

  • arp - This displays and modifies the IP to physical address translation tables used by the ARP (Address Resolution Protocol).
  • finger - Displays information about a user on a specified system that is running the finger service
  • hostname - Displays the name of the current host
  • ipconfig - Displays information about the current TCP/IP configuration, including details about DNS servers etc. Can also be used to renew and release DHCP address leases.
  • nbtstat - Displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP)
  • netstat - Displays protocol statistics and current TCP/IP connections
  • ping - Used to check if a destination host is receiving TCP/IP packets
  • route - Used to maintain and display routing tables
  • tracert - Used to view the route packets take to a destination host

For more information on these commands just enter the command with a -?, e.g. netstat -?
