[SOLVED] how to disable loading of certain modules?

After the system has booted, i do "lsmod" and see all kinds of modules i don't need, i.e. xfs, jfs, all kinds or raid and scsi stuff. I'm sure they kan be removed since "rmmod" can remove them.
I tried to add those to MOD_BLACKLIST in /etc/rc.conf but it didn't help. Where is the correct place to put modules whihch must not be loaded?
This way boot time and memory usage both can be improved.. Or am i wrong here?

Thanks a lot, exactly what i needed!

[SOLVED]Get [FAIL] when loading user specified modules.

That is it, when the system is booting i get a [FAIL] message when loading user specified modules after upgrading udev, and the kmod new module handling or something as say in the news. I dont have a modprobe.conf or a modprobe.conf.pacsave file either and creating a modprobe.conf file doesn't solve the problem. The strange thing is that the modules are loaded anyways. I mean the ones that are specified in rc.conf. I dont know if the system [FAIL] to load that modules or others...The system works fine for now too.
Thanks.
PD: sorry if you notice my poor english.

I had the same problem and removing the governor performance from rc.conf solved the problem. I tried however to remove both governors and only leave powernow-k8 (this is the only one that works for me) leaving rc.conf like this:
MODULES=(brcmsmac powernow-k8)
When I boot the laptop and check which governors are available and being used I get the following:
[netlak@soulrebel ~]$ cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to [email protected], please.

available frequency steps: 2.10 GHz, 1.50 GHz, 800 MHz

The governor "performance" may decide which speed to use
within this range.

This like as if the ondemand governor would not be available but when unplugging the laptop and check again I get this:

This shows that the ondemand module can be autoloaded when needed, so I leave rc.conf only with powernow-k8.

How to Disable the kerberos auth module

Hi,
Can someone please tell me what are the steps to Disable the kerberos auth module . I have OID<=>AD synchronized and WNA enabled. I want to disable the kerberos and do some testing and then enable it back. Is there a documentation which I can refer. I am on OracleAS Portal 10.1.2.0.0. Thanks

While Portal is the front end UI most users see for the Oracle Identity management environment, WNA and Kerberos support is really a function of the SSO<>OID environment (Portal gets it for free as part of SSO). As such, I'm going to have to punt this across to them (as they would have the most up to date information).
Can I suggest posting this question on the Identity Management Forum Identity Manager
In the mean time we, in Portal land, will look into the issue as well.

[SOLVED]How to disable USB autosuspend?

Hello!
A long time ago I installed Arch on my notebook and configured it's power saving using laptop-mode-tools. I also installed pm-utils for suspend/hibernate. USB autosuspend worked correctly - on battery every device (including mouse) was suspending and no autosuspend at all on AC. Some time ago, I don't remember when exactly, it stopped working. Now, no matter what, my mouse turns off after 2 seconds.
Here is what I did:
1. Checked my laptop-mode-tools configuration (removed comments for brevity):
cat /etc/laptop-mode/conf.d/usb-autosuspend.conf
DEBUG=0
CONTROL_USB_AUTOSUSPEND="auto"
AUTOSUSPEND_USE_WHITELIST=0
AUTOSUSPEND_USBID_BLACKLIST=""
AUTOSUSPEND_USBTYPE_BLACKLIST=""
AUTOSUSPEND_USBID_WHITELIST=""
AUTOSUSPEND_USBTYPE_WHITELIST=""
BATT_SUSPEND_USB=1
LM_AC_SUSPEND_USB=0
NOLM_AC_SUSPEND_USB=0
AUTOSUSPEND_TIMEOUT=2
So far looks good.
2. According to wiki, pm-utils might conflict with laptop-mode-tools. So I created a dummy file in /etc/pm/power.d for each of the scripts from /usr/lib/pm-utils/power.d . For the moment I don't care if I disabled too much. I just hope laptop-mode-tools covers all powersaving features.
ls -l /etc/pm/power.d
-rw-r--r-- 1 root root 0 08-08 19:58 hal-cd-polling

Still no luck.
3. As I found out, there is some kernel option CONFIG_PM_RUNTIME, which allows the kernel to autosuspend usb devices: source. It's on:
cat /proc/config.gz| gunzip | grep CONFIG_USB_SU
CONFIG_USB_SUPPORT=y
And as I read here I can disable usb autosuspend using boot parameter. So i edited my /etc/default.grub, and now my grub.cfg looks like this:
sudo cat /boot/grub/grub.cfg | grep usb
linux /boot/vmlinuz-linux root=UUID=d18cd4a4-2ebf-4874-80ff-8520016b0ed4 rw quiet usbcore.autosuspend=-1
linux /boot/vmlinuz-linux root=UUID=d18cd4a4-2ebf-4874-80ff-8520016b0ed4 rw quiet usbcore.autosuspend=-1
linux /boot/vmlinuz-linux root=UUID=d18cd4a4-2ebf-4874-80ff-8520016b0ed4 rw quiet usbcore.autosuspend=-1
After rebooting I checked:
cat /sys/module/usbcore/parameters/autosuspend
-1
Cool! It should work! But... it doesn't. The mouse still goes to sleep after 2 seconds, and:
kolzi@kolzi-laptop ~ % for i in /sys/bus/usb/devices/*/power/autosuspend_delay_ms; do cat $i;done
2000
2000
2000

2

Where doesn't this 2 (or 2000) come from? How disable this suspending and let laptop-mode-tools control it? What's going on?

For now I run
sudo systemctl disable laptop-mode.service
and changed in /etc/laptop-mode/laptop-mode.conf
ENABLE_LAPTOP_MODE_TOOLS=0
After rebooting I still have the same issues. Also, even after disabling laptop-mode-tools, the brightness changes after unplugging the laptop, so either the laptop mode wasn't disabled at all, or there is something else 'helping' me with powersaving.
@brebs
Thank you, but it looks for me more like a workaround than a solution. It could work, but it doesn't tell me what disables my mouse and where is the root of the problem.

[SOLVED] How to disable these messages at boot?

So I managed to install Arch, and set up the network. I have a Broadcom 4313 wireless chip, all I had to do is blacklist the bcma module, because it conflicted with the brcmsmac module, both are loaded by default (no need to add anything to MODULES=(), only the blacklist bcma entry to modprobe.conf)
So now I have a wlan0 interface that works perfectly fine, only I get these status messages during boot, that are totally unnecessary, see screenshot. These just pop up from nowhere, and annoy the heck out of me, disrupting the login and whatnot.
So can these be turned off somehow? I suspect they come from the brcmsmac module itself.

[Solved] How to disable vim filetype indentation.

Hello. I want to start using vim, but there is only that problem with that. In gedit I always use tabs 4 spaces wide for indentation, and I want to do something similar in vim. So in my .vimrc I used tabstop=4 and set autoindent. If I write a plain text file, it works correctly, for example, if I press tab in a new line, and the press enter, the following lines preserve the tab as indentation.
The problem starts when writing code in common lisp or python. In lisp tab is replaced by two spaces and does some weird things, and in python tab is replaced by 4 spaces. I tried including "filetype indent off" in my vimrc, or writing ":filetype indent off" directly in console, but that doesn't have any effect. The only thing that somewhat works is to disable autodinent, but then I have to manually indent every line. What can I do?
Last edited by Serge2702 (2014-11-06 20:57:54)

I keep a skeleton vimrc file to use when I have a question similar to Serge2702's. My barebones.vim:
set nocompatible
filetype plugin on
set t_co=256 " Optional, you may comment this out.
syntax on
Start vim, using the alternate vimrc file with the command, say, for a lisp file: vim -u barebones.vim file_to_edit.lisp.
Seems most filetypes default to a tab with a width of eight spaces here. To see the tabs, you can use these two commands from within vim:
:set list
:set listchars=tab:_T
Then you can try all the different setting combinations to figure out a comfortable tab width.
And there are quite a few settings that affect the width of tabs and indentation besides tabstop. There's autoindent to repeat the previous line's indentation, but this is modified if you use cindent or smartindent to set the indent according to syntax. Then there are the expandtab and smarttab settings to use spaces for tabs, and shiftwidth and softtabstop also set indentation width. I don't see why anyone has trouble figuring it out.;)

[SOLVED] Mkinitcpio fails to load every single module...

Hello,
This morning I tried to upgrade my system like every other day, except that this morning, mkinitcpio could not create both fallback and arch images which means I can't boot on my system without a livecd and a chroot now.
Here is the error list :
https://gist.github.com/Depado/5795908
I don't know what happened. I tried to run "pacman -S linux" in chroot but still the same problem.
Is there something I'm doing wrong ? Did I miss an update on the website ? Do I have to rewrite mkinitcpio.conf ?
Thanks...
SOLVED :
Reinstalling kmod, udev and mkinitcpio solved the problem of building the image.
Last edited by Depado (2013-06-17 10:51:22)

I managed to build the image properly. Now I get a "Waiting for device /dev/sda3" issue...
EDIT : I think that's because I didn't mounted /boot when I built the image. Problem solved.

How to disable Apache for certain IP?

Good day!
I have a Mac mini server with Mountain Lion Server.
It has two IP addresses:
10.0.1.2, and 10.0.1.3
I have two servers that listen on port 80:
Apache, and my own custom HTTP server.
I want Apache to listen only on 10.0.1.2:80, so my custom HTTP server can run on 10.0.1.3:80, however, in the Server configuration app, I'm not given the option to limit Apache to only one IP address.
How can I achieve this?

The default setup creates a 'Server Website' that listens to port 80 on all IP addresses, however when you create new websites you can limit which IP addresses it listens to.
Would deleting the default Server Website and creating a new one achieve your goal?
Probably a good idea to do this after a backup or on a test machine.
Also if you define a specific hostname as a website even on port 80, any requests for that hostname will be routed correctly to that website. The default Server Website would only get accessed by anything that does not match a specific hostname.
You can have lots of hostnames pointed to the same server even on the same IP and port. These are called virtualhosts and Server.app sets them up for you. Of course in your case because you want a different webserver to respond this will not help you. In your case you need to try deleting the default Server Website or run your second webserver on a different port (which is what I did).
You could have a redirect defined to go from an additional hostname/website on port 80, to a different port that your second webserver is running on. This would mean users would not need to know or remember the special port number but still avoids conflicting with port 80.
