xinetd.log

XINETD.LOG(5)							File Formats Manual						     XINETD.LOG(5)

NAME

       xinetd.log - xinetd service log format

DESCRIPTION

       A  service configuration may specify various degrees of logging when attempts are made to access the service. When logging for a service is
       enabled, xinetd will generate one-line log entries which have the following format (all entries have a timestamp as a prefix):

	      entry: service-id data

       The data depends on the entry.  Possible entry types include:

	      START	  generated when a server is started

	      EXIT	  generated when a server exits

	      FAIL	  generated when it is not possible to start a server

	      USERID	  generated if the USERID log option is used.

	      NOID	  generated if the USERID log option is used, and the IDONLY service flag is used, and the remote end  does  not  identify
			  who is trying to access the service.

       In the following, the information enclosed in brackets appears if the appropriate log option is used.

       A START entry has the format:

	      START: service-id [pid=%d] [from=%d.%d.%d.%d]

       An EXIT entry has the format:

	      EXIT: service-id [type=%d] [pid=%d] [duration=%d(sec)]

       type can be either status or signal.  The number is either the exit status or the signal that caused process termination.

       A FAIL entry has the format:

	      FAIL: service-id reason [from=%d.%d.%d.%d]

       Possible reasons are:

	      fork	     a certain number of consecutive fork attempts failed (this number is a configurable parameter)

	      time	     the time check failed

	      address	     the address check failed

	      service_limit  the allowed number of server instances for this service would be exceeded

	      process_limit  a limit on the number of forked processes was specified and it would be exceeded

       A DATA entry has the format:

	      DATA: service-id data

       The data logged depends on the service.

	      login	  remote_user=%s local_user=%s tty=%s

	      exec	  remote_user=%s verify=status command=%s
			  Possible status values:

			  ok	    the password was correct

			  failed    the password was incorrect

			  baduser   no such user

	      shell	  remote_user=%s local_user=%s command=%s

	      finger	  received string or EMPTY-LINE

       A USERID entry has the format:

	      USERID: service-id text

       The text is the response of the identification daemon at the remote end excluding the port numbers (which are included in the response).

       A NOID entry has the format:

	      NOID: service-id IP-address reason
