H.1 Troubleshooting

TCP/IP is a complicated set of networking technologies. It is easy to misconfigure the protocols or applications. Compounding these difficulties is the fact that TCP/IP requires that users be familiar with networking concepts in order to even implement TCP/IP technologies.

There are several ways to isolate problems with your TCP/IP network:

You can verify that your basic TCP/IP installation is correct. This is achieved through the use of TCPCON. For more information on this subject, refer to section 2 Troubleshooting With TCPCON.
You can use the PING utility to test connectivity between various devices at the network level. You can PING other devices using either their 32-bit IP addresses or their textual hostnames. For more information on this subject, refer to section 3 Troubleshooting With PING.
NetWare 4.1x administrators can use the IPTRACE utility to follow the exact routes that PING packets take across the Internet. This allows you to diagnose the network connections between you and a remote site. For more information, refer to section 4 Troubleshooting With IPTRACE.
You can use Telnet on a client workstation (such as a DOS, Windows or UNIX system) to test application-specific functionality, such as SMTP and POP3. For more information on this subject, refer to section 5 Testing Applications and Services.
