Why all the redundant services?

[anars]

Hi there

Can anyone please shed some light on why a default Ubuntu installation has two sysloggers and two cronjob daemons?

atd and anacron.
klogd and sysklogd.

Thanks!

[anars]

Bump.. anyone?

[anars]

Bump again. There must be a logical explanation for this :-)

[ajcham]

If I've understood what I've read correctly, sysklogd expands on the functionality of syslog and klogd, and is dependent on both.

As for anacron and atd, they are used for scheduling recurring and one-off jobs respectively. (anacron is merely an extension for cron). In the future, atd's functionality is expected to be merged into cron.

I hope these answers are satisfactory - I see this has been bugging you for some time!

RE: anacron / cron: You can view /etc/anacrontab for a list of jobs that will be run. It *seems* that the only entries in mine (Ubuntu 9.04) are to run cron.daily, cron.weekly and cron.monthly, so if you don't usually shut off your machine or don't care if the jobs get skipped if your machine is off, you can disable this service (at your own risk).

It may be a little bit off-topic but is there a karmic specific summary for what which service stands? i can't find half of my services and it seems a lot for a notebook.

I think he's figured it out by now. ;)

I'm half guessing that you mean "what are the shorthand names for my services?" If that's right, then I'd try googling the name of the service you want, or look at the list of processes and guess at which ones might be what you want, then google for those to see if you can find one that matches.


i can't find half of my services and it seems a lot for a notebook.

I'd think that a notebook would have even more services if there were any difference at all. :neutral:
