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
