The default settings of oss are insane.
These settings are for pure quality without cracking or any other kind of distortion and low-quality annoyance. This is an passthrough, bypassing some features you don't need. This gives you full quality without thinking about it anymore.
I'm a network engineer looking to better understand the network subsystem of FreeBSD (unix systems) and in particular how it differs from the linux kernel network subsystem. Any good links or books?
I believe iproute2 (this is a package, not a subsystem, right?) is used by linux, so...
Several years into compiling custom kernel to let GPS provide precise time-keeping signals, I still wonder why is that not enabled in stock kernel? With tons of modules for hardware bundled by default, many of which are obsolete, expensive or otherwise rare, it is surprising that such a...
I've modified the patch I found on these fora to allow /dev/kmem write access inside jails. The security arguments are hopefully well known: there isn't any. It's still useful for me in order to test different Xorg configs, desktop environments, and ports trees without potentially screwing up...
I am doing some light experimentation with the kernel and am writing a module. I am trying to have a /dev file functions as a TCP listening socket. So if you do cat /dev/tcp/5555, it would be the equivalent of nc -l 5555.
My general strategy is to create a socket by jumping into the...
I would like to set up a VM to work through the McKusick videos and material. Reading code and talking through it is great, but I really want to be able to tweak bits and see my changes in action. Since the release is available online, I know that I can download pretty much ISO or vm of the...
Hi , I facing the problem above after compile the kernel. Each time FreeBSD will loop boot several time until can go to login page.
My cpu info
hw.model: Intel(R) Core(TM) i3-4160 CPU @ 3.60GHz
my kernel info added my option from generic one.
# GENERIC --...
I want to get some specific I/O data from FreeBSD. IOStat command does not return what I want, so I think about using dtrace. The problem is that I am getting this error while executing dtrace command:
[2.3.1-RELEASE][admin@machine]/usr/share/dtrace: dtrace -s iotime.d
dtrace: failed to...
Hey, I just finished install FreeBSD 11 on external harddisk, and I want to ask about kernel, should I rebuild kernel after installation?
I was building kernel , and I cancel it after a hour because it was take very long time and my laptop got very hot on for it ,
I follow This instructions to...
I'm not sure if this is the right forum for this sort of question. If not, forgive me.
I made a change to this file: /usr/src/sys/modules/usb/usb/ng_lookup.c and have ran a make which produces many object files. The one I am concerned with is /usr/src/sys/modules/usb/usb/usb_lookup.o. Now I...
If I take out the laptop battery, do I confuse the acpi system?
I get kernel spam containing:
No handler for Region [RCM0]
acpi_ec0: evaluation of query method _Q42 failed: AE_NOT_EXIST
Is it due to me removing the battery, and if so, how can I tell acpi system not to look for it?
Hello, FreeBSD 11.1 (somewere after 11.1-RELEASE-p1) has begun to crash sometimes - I am on Xorg + i3 (often in a Firefox) and suddenly Xorg crashes, I can see a few lines in a console (for a fraction of a second) and then, laptop restarts.
How can I find out what happened? There is nothing...
By default FreeBSD puts kernel messages (white color) on the first console.
I know I can disable them with boot_mute in the /boot/loader.conf file, but is there a way to move them to second console instead of disabling them? ... or to redirect them to some file instead of disabling them...
I do not see the function ifhwioctl listed when I run dtrace -l. This function is located in /usr/src/sys/net/if.c.
I thought maybe this was optimized out, so I set the following in my /etc/make.conf
CFLAGS= -O0 -fno-inline
But it is still not listed.
What may be causing this lack of probe?

I'm developing an init system for many POSIX/POSIX-like systems and after reviewing part of the FreeBSD Architecture Handbook as well as part of the kernel source it appears that upon calling the init binary that it's guaranteed that root will already be mounted. I just want to verify if this...
My goal is to create a base system with only the essential tools needed to operate a modern web server. For instance I use IPFW so I don't need PF, IPTABLED and IPFILTER. However this is my first time doing this so I would like advice / feedback on anything that looks incorrect or is a bad...
