[Log et Cron] lequel choisir ?

[gnuprotek]

slt glenux,
saurais tu m'eclairer sur les differences des 4 log et 4 cron svp ...

système de logs
sysklogd/syslog-ng/metalog/msyslog

planificateur de tâches
dcron/crontab/fcron/vcron

je sai pas lequel choisir pour les deux !!! merci

[glenux]

planificateur de tâches
dcron/crontab/fcron/vcron

En attendant de trouver le reste...
Dillon's Cron (dcron)
Dillon's Cron is a multi-user cron written from scratch, similar to vixie-cron but with major differences. Attention is paid less to feature-creep and more to usability and reliability. This is the standard cron distributed with most distributions of Linux.

Package: cron
Depends: libc6 (>= 2.2.3-7), libpam0g (>= 0.72-1), debianutils (>=1.7)
Recommends: exim | smail | sendmail | mail-transport-agent
Suggests: anacron (>=2.0-1), logrotate, lockfile-progs
Conflicts: suidmanager (<< 0.50)
Description: management of regular background processing
cron is a background process (`daemon') that runs programs at regular
intervals (for example, every minute, day, week or month); which
processes are run and at what times are specified in the `crontab'.
.
Users may also install crontabs so that processes are run on
their behalf, though this feature can be disabled or restricted to
particular users.
.
Output from the commands is usually mailed to the system administrator
(or to the user in question); you should probably install a mail system
as well so that you can receive these messages.
.
This cron package is configured by default to do various standard
system maintenance tasks, such as ensuring that logfiles do not
grow endlessly and overflow the disk.
.
The lockfile-progs package is only a "Suggests" because of the poor
way that dselect handles "Recomments", but I do strongly suggest that
you install it; it prevents /etc/cron.daily/standard from running multiple
times if something gets jammed.

Package: anacron
Depends: libc6 (>= 2.2.2-2), debianutils (>= 1.7), sysklogd | system-log-daemon, exim | mail-transport-agent
Recommends: cron (>= 3.0pl1-43)
Description: a cron-like program that doesn't go by time
Anacron (like `anac(h)ronistic') is a periodic command scheduler. It
executes commands at intervals specified in days. Unlike cron, it
does not assume that the system is running continuously. It can
therefore be used to control the execution of daily, weekly and
monthly jobs (or anything with a period of n days), on systems that
don't run 24 hours a day. When installed and configured properly,
Anacron will make sure that the commands are run at the specified
intervals as closely as machine-uptime permits.
.
This package is pre-configured to execute the daily jobs of the Debian
system. You should install this program if your system isn't powered on
24 hours a day to make sure the maintenance jobs of other Debian packages
are executed each day.
Task: laptop, dialup

Package: fcron
Depends: libc6 (>= 2.2.4-4), debconf, sysklogd | system-log-daemon, exim | mail-transport-agent, adduser (>=3.25), dpkg (>>1.8.3)
Conflicts: anacron, suidmanager (<< 0.50)
Description: cron-like scheduler with extended capabilities
Fcron is a scheduler. It implements most of Vixie Cron's functionalities.
But contrary to Vixie Cron, fcron does not need your system to be up 7 days
a week, 24 hours a day: it also works well with systems which are running
neither all the time nor regularly.
.
Fcron also includes a useful system of options, such as: run jobs one by
one, run jobs at fcron's startup if they should have been run during system
down time, a better management of the mailing of outputs, set a nice value
for a job...

vcron
About:
Vcron is a graphical interface to cron and at, allowing to view, modify, delete and add programmed actions. You will no longer have to cope with the cron/at horrible syntax. Vcron is written in tcl/tk , it is a very easy to use multilingual application, with an inline manual. It has been tested on RedHat and Slackware, but it should work without problems on other platforms.

it is a very easy to use multilingual application, with an inline manual

le plus facile vcron

This is the standard cron distributed with most distributions of Linux.

le plus utilisé dcron

je vai utiliser dcron c'est celui installer sur mdk je crois ?

merci glenux

vcron est surtout une interface pour les autres cron, apparemment il ne gere pas lui meme l'execution des taches...

en ce qui concerne les syslog :

Package: metalog
Replaces: syslogd, sysklogd
Provides: syslogd, system-log-daemon, klogd, linux-kernel-log-daemon
Depends: libc6 (>= 2.2.5-13), libpcre3
Conflicts: syslogd, sysklogd
Description: Modern logging daemon
Metalog is a modern replacement for syslogd and klogd. The logged
messages can be dispatched according to their facility, urgency,
program name and/or Perl-compatible regular expressions. Log files
can be automatically rotated when they exceed a certain size or
age. External shell scripts (e.g., mail) can be launched when
specific patterns are found. Metalog is easier to configure than
syslogd and syslog-ng, accepts unlimited number of rules and has
(switchable) memory bufferization for maximal performance.

Package: sysklogd
Replaces: syslogd
Provides: syslogd
Depends: libc6 (>= 2.1.2)
Conflicts: syslogd
Conffiles:
/etc/syslog.conf a1bcc45dda2c678c3976db114a3c9150
/etc/init.d/sysklogd 6af4a1b9afd465c794e0ca90dc06bc76

/etc/cron.weekly/sysklogd f59b219fd05df2cfbcd089dc046141db
Description: Kernel and system logging daemons
This package implements two system log daemons. The syslogd daemon is
an enhanced version of the standard Berkeley utility program. This
daemon is responsible for providing logging of messages received from
programs and facilities on the local host as well as from remote
hosts.
.
The klogd daemon listens to kernel message sources and is responsible
for prioritizing and processing operating system messages. The klogd
daemon can run as a client of syslogd or optionally as a standalone
program. Klogd can now be used to decode EIP addresses if it can
determine a System.map file.

Package: syslog-ng
Provides: system-log-daemon
Depends: libc6 (>= 2.2.4-4)
Recommends: logrotate, linux-kernel-log-daemon
Conflicts: system-log-daemon, sysklogd
Description: Next generation logging daemon
Syslog-ng tries to fill the gaps original syslogd's were lacking:
* powerful configurability
* filtering based on message content
* message integrity, message encryption (near future)
* portability
* better network forwarding

Personnellement, j'utilise le dernier (syslog-ng)

[gnuprotek]

si j'ai bien compris syslog-ng est plus performant et metalog est plus facilement configurable

je peu prendre syslog-ng je suppose quand meme que c'est pas un truc a configurer tout le temps (j'ai jamais du le configurer au aupart avant)

donc c'est mieux d'etre performant ???? non !!!!!

qu'en penses-tu ?

[glenux]

bof, c'est toi qui voit :)

[gnuprotek]

bof, c'est toi qui voit

ça ma'arrange ta reponse lol...

dans la doc de gentoo il disent si on sai pas on prend metalog alors je vai suivre la doc

encore merci pour tout
