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
