Chapter 19 DCE (Distributed Computing Environment) Messages

The messages in this chapter are sent by the Distributed Computing Environment (DCE) subsystem. The subsystem ID displayed by these messages includes DCE as the subsystem name.




	NOTE: Negative-numbered messages are common to most subsystems. If you receive a negative-numbered message that is not described in this chapter, see Chapter 15.

dce-message-code program-name (program-pid) severity component subcomponent src_file src_line thread-id text.

`dce-message-code`	specifies the DCE message code number.
`program-name`	is the name of the program that generated the message.
`program-pid`	is the OSS PID of the program that generated the message.
`severity`	is the message severity (FATAL, ERROR, WARNING).
`component`	is the component name of the software that generated the message.
`subcomponent`	is the subcomponent name of the software that generated the message.
`src_file`	is the name of the C source file at which the message was generated.
`src_line`	is the line number in the source file at which the message was generated.
`thread_id`	is the thread ID of the thread that wrote the message (a thread control block address).
`text`	is the detailed text of the message.

Cause This error was generated by the DCE subsystem. The cause can be determined by using the dce-message-code to find the error description in the DCE Problem Determination Guide. The dce-message-code is a hex number that can be used to find the symbolic name of the event in Appendix A of the Guide. The symbolic name can then be used to find the event explanation in the main part of the same book. Alternatively, the message text can be used to locate the symbolic name of the event in Appendix B of the manual.

Effect Refer to the entry for the error in the DCE Problem Determination Guide. The error’s effect is described in the paragraph titled “Explanation.”

Recovery Refer to the entry for the error in the DCE Problem Determination Guide. The error’s recovery is described in the paragraph titled “Action.”

Event Messages Logged by Security Daemon

The Security Daemon (SECD) logs messages through EMS for user information. The messages have the event identifier, authentication time stamp (optional), error code or message (if any), host address, and requesting client and server information.

AS_REQ

AS_REQ authtime error-code-or-message, host, requesting-client-and-server-information

`authtime`	specifies the authentication time stamp (optional)
`error-code-or-message`	provides the error code or error message (if any)
`host`	specifies the host address
`requesting-client-and-server-information`	provides information about the requesting client and server

Cause This event is logged by the Authentication Server (AS) for the following reasons:

When a ticket is granted to the requesting client. (This is an informative message.)
When AS fails for some reason (detailed in the logged message) while processing the request from a client for its credentials.

TGS_REQ

TGS_REQ authtime error-code-or-message, host, requesting-client-and-server-information

`authtime`	specifies the authentication time stamp (optional)
`error-code-or-message`	provides the error code or error message (if any)
`host`	specifies the host address
`requesting-client-and-server-information`	provides information about the requesting client and server

Cause This event is logged by the Ticket Granting Server (TGS) for the following reasons:

When a Ticket Granting Ticket (TGT) is issued to the requesting client. (This is an informative message.)
When an error occurs (detailed in the logged message) while processing a request for TGT, or for a ticket to a particular service, from a client.

PROCESS_TGS

PROCESS_TGS authtime error-code-or-message, host, requesting-client-and-server-information

`authtime`	specifies the authentication time stamp (optional)
`error-code-or-message`	provides the error code or error message (if any)
`host`	specifies the host address
`requesting-client-and-server-information`	provides information about the requesting client and server

Cause This message type is logged by the Ticket Granting Server (TGS) to indicate that an error (detailed in the log) has occurred while a request was being processed. This message is logged in the following instances:

When TGS processes a request from a client for a ticket to a particular service it verifies whether the server principal in the ticket belongs to the local realm. If it does not, TGS rejects the request because it can only issue tickets for servers in its own realm. In this case, TGS logs an appropriate error message.
When the cell time is out of sync (clocks on DCE master and client machines have a time difference of more than 5 minutes) and an authenticated client requests a ticket, TGS verifies the authenticator time stamp. Since the authenticator lifetime is only 5 minutes, TGS rejects the client request with an appropriate error message.
