LinuxSecurity.com: A design flaw (CVE-2010-4345) in exim4 allowed the loal Debian-exim user to obtain root privileges by specifying an alternate configuration file using the -C option or by using the macro override facility (-D option). Unfortunately, fixing this vulnerability is not [More...]
UPDATE-EXIM4DEFAULTS(8) System Manager's Manual UPDATE-EXIM4DEFAULTS(8)NAME
update-exim4defaults - Manage exim4 daemon default file.
SYNOPSIS
update-exim4defaults [ --qflags flags ] [ --queuerunner combined|queueonly|separate|ppp|no|nodaemon ] [ --queuetime time ] [ --commonop-
tions options ] [ --queuerunneroptions options ] [ --smtplisteneroptions options ] [ --remove-common options ] [ --remove-queue options ] [
--remove-smtp options ] [ --force|-f ] [ --help|-h ] [ --init ]
DESCRIPTION
update-exim4defaults allows one to set run parameters for the Exim daemon in /etc/default/exim4. Its main purpose is for interaction with
packages enhancing Exim like virus-scanners that need to change the way the exim daemon is started.
OPTIONS
--help|-h
Print short usage instructions and exit.
--qflags flags
Set qflags, special flags given to exim directly after the "-q". See exim(8) for more information.
--queuerunner combined|queueonly|separate|ppp|no|nodaemon
Should the init script start one daemon that listens on the smtp port for incoming connections and runs the queue at regular inter-
vals (combined) , or should it start two separate daemons, one listening on the smtp port, the other running the queue (separate) ,
or should the queue only be run by /etc/ppp/ip-up.d/exim4 (ppp) , or shouldn't we run the queue at all, for example if you'd rather
do this with cron ? Or should we only start a queuerunner (queueonly) or no daemon at all (nodaemon) ?
--queuetime time
In which intervals should we run the queue? This passed as option -q<qflags>time to Exim, e.g. -q30m or -qq1h.
--commonoptions options
Options passed both to queue-running and listening instances of Exim.
--queuerunneroptions options
Options only passed to the instance of Exim running the queue.
--smtplisteneroptions options
Options only passed to the instance of Exim listening on the SMTP port.
--force|-f
Without this option update-exim4defaults exits with an error if at least one of the options --queuetime, --commonoptions,
--queuerunneroptions or --smtplisteneroptions is used and the corresponding value in /etc/default/exim4 is already set to a nonempty
value.
--remove-common option
Try to remove the given option from COMMONOPTIONS.
--remove-queue option
Try to remove the given option from QUEUERUNNEROPTIONS.
--remove-smtp option
Try to remove the given option from SMTPLISTENEROPTIONS.
The --remove-commands cannot be used at the same time as any of --commonoptions, --queuerunneroptions or --smtplisteneroptions. The
--remove-commands will additionally remove whitespace at the beginning and the end of the option and exchange multiple spaces wi a single
one.
--init create a default /etc/default/exim4 file and exit immediately. Unless --force was also specified update-exim4defaults exits (suc-
cessfully) without doing anything if /etc/default/exim4 already exists. All other options are ignored.
EXIT STATUS
0 change was successful or nothing needed to be done.
1 generic error: wrong options, unreadable configuration file, etc.
2 QUEUEINTERVAL was already set.
4 COMMONOPTIONS was already set.
8 QUEUERUNNEROPTIONS was already set.
16 SMTPLISTENEROPTIONS was already set.
32 QFLAGS was already set.
64 --remove-something failed, i.e. the value of the option was not changed.
Exit codes 2 to 32 will be summed up, if more than one unsuccessful option was given.
FILES
/etc/default/exim4
The configuration file.
/etc/init.d/exim4
The Exim init-script.
/etc/ppp/ip-up.d/exim4
The queuerunner in this file also uses COMMONOPTIONS and QUEUERUNNEROPTIONS and does not run if QUEUERUNNER=no.
BUGS
This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
would be greatly appreciated.
