Occasionally I develop debug techniques and tools that I think will help the general VM TCP/IP community. Here are my offerings.

If you have comments, please send mail to Alan_Altmark at us.ibm.com. You will find me in the IBMVM, IBMTCP-L, and LINUX-390 list servers.

Pointers

• TCP/IP Broadcast on a z/VM Guest LAN by Simon Williams.

• Cloning TCP/IP Servers
• Custom TCP/IP Translation Tables
• Code Page Definitions
• GETDDIR ASSEMBLE: A program to extract a user's initial directory from the system.
• TCPC: A modified version of the VM TCP/IP sample client that can be compiled for OpenExtensions or TCP/IP. Instructions are in the prolog.
• A sample "echo" client and server that illustrate the use of TCP/IP and IUCV sockets in z/VM OpenExtensions. The server also shows the differences in using single-threading, native CMS multitasking, and POSIX functions.
  • Client (tcpecho.c)
  • Server (tcpechos.c)
  • header needed by both (tcpecho.h)
  Build instructions are in the prologues.
• A sample program that provides the infrastructure necessary to interface with the RACROUTE calls issued by the z/VM NFS and FTP servers.
