No sound in dosbox

  This is not the particular game itself, it's dosbox.  I.e. when I
start up dosbox, it says...

[d531][waltdnes][~] dosbox
DOSBox version 0.74
Copyright 2002-2010 DOSBox Team, published under GNU GPL.
CONFIG:Loading primary settings from config file /home/waltdnes/.dosbox/dosbox-0.74.conf
MIXER:Can't open audio: No available audio device , running in nosound mode.
ALSA:Can't subscribe to MIDI port (65:0) nor (17:0)
MIDI:Opened device:oss

  It used to work before I re-installed Gentoo (32-bit ==> 64-bit).
Audio works in linux Youtube, mplayer, mpg123, etc.  It's just dosbox
that fails.  Google searching did not help.  I saw a few references to
checking for missing /dev/dsp and /dev/audio.  They are present on my
system.  Any ideas?

Problems with "mailto" (fcrontab)


In my fcrontab file I added:
&b(1),mailto(root) * * */14 * * /home/mccramer/bin/

I would exspect to get mail each time the command is run.

&b(1),mailto(root) */2 * * * * /home/mccramer/bin/

""'s last line is 'date' so this command prints something.

I would exspect to reveive mail from fcron but: no.

Is there something else to configure? Do I need to setup a
complete mailserver for log mails? Do I have to create a
fully fledge email account?

Slightly confused...

Postfix 2->3 upgrade

Can anyone comment on this upgrade?  Is there much to update in the
config files?  I did a search but didn't come up with much which I
think is a good thing.

Re: Poor mans audio in the world of the great Jack D.

Staring into the dark abyss of the fathomless mysteries,
the humble scholar spake: "Shit! I'm out of ideas, dude…"

The .asoundrc snippet works out of the box for me, but I use it just
for Firefox, to be honest, every other audio software
There are more solutions at

Failing that, I don't know. Maybe qsstv does not belong to the ALSA tribe
but to the OSS one, and uses the ALSA OSS emulation, and this prevents
the ALSA jack plugin to work?

[~and64] Headsup for google-chrome users

I just wasted some time figuring out this mess:

I just updated google-chrome, which printed this confusing warning message:

"CONFIG_USED_NS not seen when it should be"

First, there's a typo:  it should read "CONFIG_USER_NS"

Then, after I figured out that CONFIG_USER_NS is a kernel config item,
requiring reinstallation of my kernel, I wasted more time figuring out
(for the n'th time) that you shouldn't just change a single kernel config
item and do "make" because that shortcut can break important things.

No, you should do "make clean" first, and then do "make" etc.

Then, after finishing that mess, you then need to re-install ati-drivers
(if you use them) because CONFIG_USER_NS breaks the ati-drivers too.

So, re-install ati-drivers, reboot, etc, all of which will make you late
for work, like I am now :p

logjam vulnerability

Heard of logjam today ->

Tried to fix it following:

for postfix that works

for apache-2.2.29 (=stable gentoo package) I googled that one has to

# cat dhparams.pem >> /my/ssl_cert_file

and restart apache

But even then the tests at and

tell me I have too weak DH groups

Does anyone have the same issue? And a solution?

Thanks, regards, Stefan

user config provisioning

I am currently trying to slim down and minimize my own few machines.

Way too much customer servers out there so I'd like to keep it simple in
here at least.

This lead me to configuring and provisioning my machines via ansible.

The goals:

* make sure that my user exists
* roll out configs/dotfiles/git-repos/home-dir
* maybe roll out some system-configs as well (systemd-units, timers) /
... separate ansible-role, OT here


I have set up and maintained quite a list of bash-aliases to access my
customer-servers in daily work.

Something like:

alias abcd-server='ssh -p 51023'  # demo only

This is based on ssh-pubkey-authentication, sure.

My questions:

* if I have a user X on each machine, should each userX <at> machine have its
own ssh-pubkey? Or is it OK to roll out the same ~/.ssh to all machines?

howto make github look nice


One of the things I find ugly about github is the first appearance
of the main (base) page of a given project.  One thing I really like about
sourceforge is how some projects look much more professional. I do not need
(nor want) a lecture on why this is. I only want solutions or ideas of how
to create a github base page that looks much more (www) presentable like
this sourceforge page:

So ideas on how to do this are most appreciated; or facts as to why
it is not possible with github..... Also notice in the 'menu bar' the
[GIT] functionality built in. Slick. Really slick and this is how I want
my pages to look, as soon as I become brave enough to start moving codes
from my workstations (ugly; no gui) to the larger world for folks to 
start playing with some codes and overlays.

I want folks to look at my projects and they have an  aesthetically 
pleasing appearance......   (I need an edge!).

Glad this was fixed.  Thanks for letting us know.
