Testing TCP/IP functionality
Testing TCP/IP functionality
There are several testing utilities available in the Microsoft TCP/IP application
suite. Examples of the output of two Windows 95 TCP/IP utilities, Ping.exe and
Winipcfg.exe, are included below. On Windows NT/2000/XP, the equivalent
utilities are Ping.exe and Ipconfig.exe.
The Ping.exe utility shows TCP/IP networking response and can be used to show
connectivity between computers. For a mapped network volume connection, a
client can ping the server and vice versa to check that they have basic connectivity
at any time.
Pinging a local host shows basic local TCP/IP functionality. The address used in
the following example identifies the local host on the network.
Pinging a local host
In a Windows DOS prompt dialog box on a Windows 95 computer with a
computer name Win95PC1, the following command is entered:
c:\> ping LocalHost
This gives the following results:
Pinging Win95PC1 [127.0.0.1] with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
This test indicates that the TCP/IP stack is installed and operating.
