Heya fedora peeps.

Quick question and very basic for you guys. Im a Debain fan but im helping a friend install a Fedora 16 on his laptop. Say if i want to turn off ssh, i normally just go /etc/init.d then chmod -x ssh. But how do i do that from the command line on a fedora system ?

Basic, i've read something about systemctl :S, but would prefer doing chmod -x, if possible in a Fedora environment.

Thanks for your help

You can find them in /etc/rc.d/init.d.

Perhaps

where did this idea of stopping it being executable come from? I've never heard of that and just sounds crude and clunky.

I believe it's the "standard" UNIX way of disabling init scripts. It's still the standard way of disabling Slackware's init scripts.

Yep, standard on Slackware, because the main init script checks if they are set to executable and only runs them in that case. But not the correct way on Debian.

that sounds horrible. Wonderfully simple, sure, but that doesn't make it good. the executable flag means the file is execut**ABLE**, not that it should be executed. That's a hack.

It's not "horrible": it's the BSD Init-Style!
You have many different init scritpts in the init path and a main script check for the ones with the executable flag and run them.
Utils and scripts like chkconfig, service [name] start/stop/restart, ntsysv were created to make the daemons-services management easier.

Forget everything you know about /etc/init.d. Examine the files in /usr/lib/systemd/system. The *.service files control services. To make one active, create a link in /usr/lib/systemd/system/multi-user.target.wants; delete the link to disable a service. Suffering from congenital indolence, as I oftentimes do, I use "systemctl" to do all that.

> systemctl status sshd.service
sshd.service - OpenSSH server daemon
Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled)
Active: active (running) since Tue, 31 Jul 2012 06:58:26 -0700; 6s ago
Process: 7905 ExecStartPre=/usr/sbin/sshd-keygen (code=exited, status=0/SUCCESS)
Main PID: 7910 (sshd)
CGroup: name=systemd:/system/sshd.service
└ 7910 /usr/sbin/sshd -D

> systemctl stop sshd.service
sshd.service - OpenSSH server daemon
Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled)
Active: inactive (dead) since Tue, 31 Jul 2012 06:59:56 -0700; 3s ago
Process: 7910 ExecStart=/usr/sbin/sshd -D $OPTIONS (code=exited, status=0/SUCCESS)
Process: 7905 ExecStartPre=/usr/sbin/sshd-keygen (code=exited, status=0/SUCCESS)
CGroup: name=systemd:/system/sshd.service

[notice that the service is still loaded, or enabled]

> systemctl disable sshd.service
rm '/etc/systemd/system/multi-user.target.wants/sshd.service'

[now the sshd service will no longer start - reverse the process, enable and start, if you want to run sshd again]

> systemctl --help
> man systemctl

IMHO, systemd is a lot easier to deal with than all of those /etc/init.d or /etc/rc.d files. My /etc/init.d directory is empty. (The *.wants directories coorespond to different run-levels.)
