I'm trying to determine the minimum services for correct server operation and I am getting annoyed by the modules_dep daemon.

What is this service used for?

Thank you in advance

EDIT: ps ax output

wich modules_dep output /usr/bin/which: no modules_dep in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)

But the daemon is there chkconfig --list | grep modules_dep

modules_dep     0:desactivado   1:desactivado   2:activo        3:activo        4:activo        5:activo        6:desactivado

It's a VPS from Strato.

I've never heard of this daemon and quick googling for "module_dep" shows your question on SF as a result #1, could you please provide more details like ps ax and which module_dep, etc? – Alex Aug 8 '12 at 12:18
I've been googling for a long time and I am not getting any clue about this. And the correct name is modules_dep, I forgot the 's' – Quaiks Aug 8 '12 at 12:36

Okay, this looks like a one-time bootup script, not a daemon. So it does not consume resources after bootup, nothing to worry about. I guess you can browse its source code at /etc/init.d/modules_dep. I can't find it in standard CentOS install so it should be custom.

Yes!! It's a small script that fixes module.dep for iptables. Thank you! I should start looking at /etc/init.d/ folder. My fault. – Quaiks Aug 8 '12 at 12:47
