Mute status on ThinkPad

Hi folks,

I couldn't find a way to get mute status on ThinkPad. The standard
"mixer" and "aumix" do not have such control to get/set.

"sysctl hw.snd" doesn't show anything related to mute either.

The hardware key works, but it's not reflected anywhere.

Does anybody have ideas on it?


PS My ThinkPad is T430

Btsync on FreeeBSD

I am having a problem that I just cannot seem to work around, I have
"btsync-2.2.6" installed on a FreeBSD-10.2-RELEASE-p7 machine. I am using it
to primarily link files from a Windows 10 PC. I am using the commercial
version on the Windows PC.

The Windows part works fine. It is when I place the link into the "manual
connection" box on the FreeBSD. The link must be copied and manually
inserted. The simple clinking on of the link that works fine on a Windows
machine fails on FreeBSD. The real problem is that I now receive an error
that "btsync" does not have permission to write to that folder. I have
changed the folder locations to my home directory. I finally got around
that problem by changing the OWNER/GROUP to btsync as the owner leaving
myself as the group. Now, btsync will sync with the Windows machine. This
does not solve all of my problems though. I now cannot save, copy or move any
files to this "btsync" directory unless I do so as the superuser. I even
tried changing the directory permissions to "0777". Now, I can write to the
directory; however, "btsync" will not sync those files to the Windows
machine. Apparently because the owner of the file is not "btsync". Also, I am
forced to manually change the permissions of any sub-directories that
"btsync" creates. A real PIA in several instances.

I am at a loss here as how to make this work. I was thinking that perhaps
"acls" would be the an-swer, but I do not know how to use them and
specifically, how to use them on only one directory and any sub-directories.

If anyone has experience with "btsync", I would love hearing about your

kbdmux disabled --> no useable keyboard?!


  I'm setting up a multiseat workstation, where two users, with two
  monitors, two keyboards, two mice and two X sessions can be
  connected to the same computer at the same time.

  For this to happen, one of the things that is necessary to do is to
  disable kbdmux in order for the two keyboards to be considered

  In the past, I've accomplished this with syscon, which had other
  problems.  But now with vt, when I disable kbdmux either on
  /boot/device.hints or in /boot/loader.conf with: 

  No keys are recognized by the OS, although dmesg seems to know about
  the existence of the USB keyboard.

  So, I'm stuck on this.  Is this an intended feature of kbdmux?  What
  should I do to be able to use two keyboards (in X) independently,
  and still be able to use one in the console.

  I'm running FreeBSD 64bits 10-STABLE with a recent upgrade.

mbuf statistics


On a freebsd 9.3 system:

 > vmstat -z | egrep "mbuf_cluster|ITEM" | column -t
mbuf_cluster:  2048,  10284,  1152,  56,   4237,  0,    0

 > netstat -mb | grep "mbuf clusters in use"
512/696/1208/10284 mbuf clusters in use (current/cache/total/max)

one can see that:

current + cache == total == USED + FREE

but the current/cache values as reported by netstat
are very different form USED/FREE values reported by vmstat, so
they should have different meaning.

Ny question is: what us the exact meaning of USED/FREE and
current/cache values? Is there any relationship between them?


Best regards

Unzip utility choice decision

The unzip utility which comes OOTB is different than the one which installs with `pkg install unzip`. The
latter one is the real unzip utility which accepts -uoq switches together. The former one complains
"unzip: -n, -o and -u are contradictory".
Without being able to -uoq causes a race with two unzips attempting to overwrite the same file at the same
time. -u prevents existing files from being overwritten if they haven't been updated and allows us to run
any number of unzips in parallel.
After installing FreeBSD, I have to rename "/usr/bin/unzip" to "/usr/bin/unzip2" followed by "pkg
install unzip" and then "ln -s /usr/local/bin/unzip /usr/bin/unzip".
If the licensing permits, please consider replacing the default unzip utility with the one available in
ports. This way it is convenient to write a cross-platform build/install scripts for software without
additional checks.

Forbid user set file mtime in the past


Is there any way to forbid users to set file modification time in the past?

I am asking because many  php viruses somehow set modification time in 
the past
and just checking what php files were created/modified for the last n 
hours just does
not work at all.
