Utility Programs for TCP/IP Diagnostics
Example:
Check connection to local computer. The local computer can normally be reached under the
loopback address 127.0.0.1 and the name localhost.
C:\>ping localhost
PING is executed for the local host [127.0.0.1] with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<10msec TTL=128
Reply from 127.0.0.1: bytes=32 time<10msec TTL=128
Reply from 127.0.0.1: bytes=32 time<10msec TTL=128
Reply from 127.0.0.1: bytes=32 time<10msec TTL=128
Messages:
If the remote computer does not reply, the error can be deduced from the messages.
● Invalid IP address (unknown host):
The host name could not be converted to a valid IP address. This message is generated
when the DNS server cannot be reached or is out of service. This message is only output
when the host is addressed using a name.
● Destination host not available (network unreachable):
There are no valid routes to the destination system. The destination address could not be
reached, as a gateway is out of service or was not correctly specified on the local host.
● Timeout:
The computer has a route to the destination computer but there is no reply. The message
reaches the destination host, but cannot be returned. This error is caused by incorrect rout-
ing of the destination computer.
C.1.2 ipconfig
The ipconfig program is a quick way of querying the TCP/IP network configuration. In this
way you can display IP addresses, netmasks, gateways and network card statistics. It also en-
ables IP addresses assigned via DHCP to be released or renewed.
-w <Timeout> Timeout in milliseconds to wait for each reply. If this time elapses, a time-
out message appears. This value is set by default to 1000 (1s). It is advis-
able to set this value to 5000 (5s) or 10000 (10s) in the case of slow con-
nections such as via modem or GSM. If the reply takes more than 1
second, a timeout message will be received even though a connection is
possible.
