TCP/IP Services for OpenVMS

This manual, HP TCP/IP Services for OpenVMS: Tuning and Troubleshooting, serves as a guide for system and network managers to diagnose networking issues and optimize performance. It is divided into two chapters and an appendix:

• Chapter 1: Troubleshooting Techniques and Tools – Details how to identify and isolate network issues, including connectivity testing, monitoring interface parameters, using diagnostic tools like ping, netstat, tcpdump, and TCPTRACE, checking name server operations, and managing routing.
• Chapter 2: Tuning Techniques – Explains how to adjust kernel subsystem attributes, including socket and Internet subsystem settings, to improve system performance. It also covers tuning server applications and resolving performance issues such as improving Gigabit Ethernet performance using jumbo frames.
• Appendix A: Troubleshooting Utilities Reference – Provides reference material for network management utilities such as arp, dig, ifconfig, ndc, netstat, nslookup, ping, route, sysconfig, sysconfigdb, tcpdump, TCPTRACE, and traceroute.
