Before you begin customizing, it is assumed that you know what
configuration data sets are used by the TCP/IP address space, their
search order, and considerations for what type of TCP/IP stack you
will be running in your environment (for example, Enterprise Extender
(EE) and multiple stacks).
See IP configuration overview for this information.
After reading this information, you will know how to configure
and start syslogd and the TCP/IP stack. You should understand the
relationships of TCP/IP configuration files as they apply to the TCP/IP
address space. The four main configuration files that you will be
working with are:
- TCPIP.DATA
- PROFILE.TCPIP
- HOSTS.LOCAL
- ETC.IPNODES
You should be able to use the following commands to verify customization:
- TSO PING and z/OS® UNIX ping
- Sends IP datagrams to a specified destination host, requesting
a reply, and measures the round trip time. This helps you to verify
the interfaces defined to the TCP/IP address space.
- TSO NETSTAT, z/OS UNIX netstat, and DISPLAY TCPIP,,NETSTAT
- Queries TCP/IP about the network status of the local host or the
contents of the resolver cache. With Netstat, you can verify most
TCP/IP customization values that can be set from PROFILE.TCPIP. You
can also display detailed information about the contents of the system-wide
resolver cache, or statistical information such as the number of cache
queries.
- TSO HOMETEST
- Verifies your host name and address configuration.
- TSO TRACERTE and z/OS UNIX traceroute
- Displays the route that a packet takes to reach a requested destination.
