Troubleshooting Techniques and Tools
1.3 Using Online Help
For information about TCP/IP user commands, enter the HELP command at the
DCL prompt. For example, to display online help about the FTP command, enter
the following command:
$ HELP FTP
Some user applications provide additional information from the user interface.
For example:
$ FTP
FTP> HELP
Commands for obtaining online information from the application user interface
are application specific. Refer to the description of the application in the HP
TCP/IP Services for OpenVMS User’s Guide for specific instructions.
To display information about a TCP/IP error message, enter the HELP/MESSAGE
command, followed by the error message name. For example, if you receive the
FTP_CONHST error when you try to establish an FTP connection, enter the
following command to get information about how to respond to the error:
$ HELP/MESSAGE FTP_CONHST
FTP_CONHST, error connecting to remote host ’host’
Facility: TCPIP, FTP Server
Explanation: An error occurred in the FTP client. A network error occurred
or the network is not active.
User Action: Make sure network communication is active on the system.
1.4 Using OpenVMS ANALYZE Extensions
TCP/IP Services provides extensions to the OpenVMS DCL command ANALYZE,
allowing you to analyze TCP/IP operations on the system. To obtain information
about using the TCP/IP extensions to the SDA interface, enter the following
commands:
$ ANALYZE/SYSTEM
SDA> TCPIP HELP
