Can I disable syslog-ng and cron daemons?

Pooh-Bah · 2011-07-23 01:22:08

I really don't use two this daemons - syslog-ng and cron. Can I remove this from /etc/rf.conf?

I do not understand system logs and no needs 24/7 to read logs.
Also, if I need to read system logs, I just run it temporary...

Also I dont use cron. For archlinux cron is critical daemon? If not - can I disable?

What if your system crashed and you don't have logs to tell you what happened? Do you reinstall or pull out a crystal ball out of the closet? ;-)
Many apps use cron to perform updates and maintenance.

Those daemons don't clutter the system and don't eat up gobs of resources so why do you want to remove something you don't understand?

Pooh-Bah · 2011-07-23 01:31:51

About syslog-ng: I long time use Windows and never use anything logging (just don't know about it). If my system crashed or computer will be broken - I tested my hardware. I use my computer as desktop: music, video, chats, web-surfing. Thats all.

About cron install apps: Xorg (minimal), firefox, ncmpcpp, irssi, rtorrent, mplayer. Thats all.

Thanks for reply.

Do you backup your data? That's one very common application of cron.
I see that shadow uses cron to check the integrity of password and group files: /etc/cron.daily/shadow

Pooh-Bah · 2011-07-23 01:46:04

No, I did not touch cron since the installation and don't use this for backup, scripts etc.

I single user in system, do not change password or anything else.

crond does some system maintainance that you probably want, e.g., man-db, updatedb, logrotate (necessary if you use the log facilities). Look into /var/spool/cron/ and /etc/cron.*/ for the details.

logs are useful for tracing down problems. Providing a log when you ask for help helps greatly. But it's not essential for functionality, of course.

Pooh-Bah · 2011-07-23 02:14:19

Okay, I remove syslog-ng from daemons. Now cron...

/etc/cron.d:
prune-cronstamps*

/etc/cron.daily:
logrotate*  man-db*  shadow*

/etc/cron.hourly:
adjtime*

/etc/cron.monthly:

/etc/cron.weekly:

prune-cronstamps - I think this for cron, and if I don't use cron - no need to this.
logrotate - for contol logs. syslog-ng management logs, and this disabled. logrotate is no more need?
man-db - for update man pages databases? I can do it manually when I need it, - once a year because not install new apps.
shadow - hm.. dont know, but I did not touch group and password files, and not change password etc.
adjtime - linux and hardware clocks - two different clocks? clock accuracy is not critical

And of course, if anything needed - I always can do it manually (like update man-db).

Added about syslog-ng: when system can crashed? Only when update.
If it critical, like kernel, - I always can use "ArchLinux Fallback" from grub menu list, yep? No problem, I think. No need to read logs.

Not exactly, see /etc/logrotate.d/

But anyway, if you prefer to do all these manually, I don't see a problem.

Pooh-Bah · 2011-07-23 02:46:24

# echo "rm /var/log/*.log" >> /etc/rc.local.shutdown

logrotate not needed?

(Edit)

/etc/rf.conf:

DAEMONS=(@alsa network)

Awesome. True minimalism

Instead syslog-ng running minilogd, don't know - how to disable it?

lolilolicon · 2011-07-23 03:33:04

In rc.sysinit:

# start up our mini logger until syslog takes over
/sbin/minilogd

Comment it out, but I don't know if it will do any harm.

I'm not sure if I understand it correctly: you want to stop minilogd from running?
Try commenting it out in /etc/rc.sysinit - but I'm not responsible for any problems this might cause.

Edit: Now you have a second opinion ;P

Even windows has a logging utility. It's usefulness is questionable at best though...

Well, good luck with your 'minimal' system.

Why disable something that takes next to no resources and have usefull features?

Awebb · 2011-07-23 14:42:48

There will be the day you encounter a problem and you will be told to post /var/log/<fancylogfile>. You will have to tell them you can't because you disabled the log file daemon. They will shrug, shake their head and do something else.

Like when system is clean and minimum system processes, CPU/RAM usage.
I newbie in Linux and its just experiments for the experience.

Good on ya Pooh-Bah. Its your system to do with as you please. As long as you have listened to the advice given and heeded the warnings I think you are correct in following your course of action. Linux is about experimenting and trying to do things the way you want. Sometimes we have to learn by trying. Even if the attempt ends in failure something can always be learned.

Doing what you are doing is exactly how I taught myself about the services in Windows. I turned them off and looked at what broke. If i needed it I turned it back on. If I didn't it stayed off.

Arch Linux
