Ok. I wasn't sure because it seems rather complex with all this RPC
stuff.

That's probably better. I was thinking about NFS because I don't have
enough disks on the backup server. Those files should go to tape.

Thank you for your quick reply!

NFS is a very old protocol that very likely has as yet undiscovered
vulnerabilities.  I would expect that the likelihood of there being even
a theoretical vulnerability that would allow a malicous user on the
server to gain access to a client would be very low.

However, I think you are going about this all wrong.  A backup script or
program would have to touch/examine every file to determine its age, MD5
sum, or whatever other feature drives the backup/no-backup decision.
NFS is actually a terrible protocol for this sort of thing.

You are almost certainly better off creating a backup user on the DMZ
machine, setting its shell to something like rsync-only (check out the
rssh package, for example), and then using something like rsnapshot (my
personal favorite) or another rsync-based backup script/program.

That is likely to be more secure and I can practically guarantee it will
have better performance.

NFS client and untrusted server

[Chris]

All,

I want to backup a DMZ-server to an internal backup server.

Is it reasonable to setup an NFS-server in the DMZ and mount it from
the inside server using the read-only, noexec and nosuid options? Could
an attacker gain access to the internal server this way?

Does anyone use such a setup?

You might look at the Graphics Layout Engine
available under debian stretch 

  $ aot show gle-graphics

GLE is a graphics scripting language designed
for creating publication quality figures
such as charts, plots, graphs, and diagrams.

It supports various chart types (including function plot,
histogram, bar chart, scatter plot, contour plot, color map,
and surface plot) through a simple but flexible set
of graphing commands ;

more complex output can be created by relying on i
ts scripting language, which is full featured
with subroutines, variables, and logic control.

And then there's Tikz, depending on what level of commitment you wish to
put into it.

http://www.texample.net/tikz/

I'm surprised that no one has mentioned FreeCAD in this whole 
discussion. It is my goto for any cad work. It has an architecture 
workbench, is under heavy development and is reasonably intuitive. It 
will be in your distro. just apt-get install freecad. It also handles 
AutoCAD files among quite a few others.

If and once you get back up, a thread not long ago reminded me about
"free -m". I've had odds and ends of problems like this blank screen
myself over time.

That goes back to me at least once writing about how I was sometimes
forced to reboot fresh... then the last previous session would come
back up in its entirety, e.g. browser open with last used tabs, text
editor with last multiple accessed files, etc. That was NOT expected
behavior on a fresh reboot. :)

With "free -m", I'm seeing inconsistencies in what comes in and out of
SWAP after mine goes into some level of sleep/hibernation. Sometimes
it will clear out completely, and other times almost nothing exits.
That "almost nothing exits" part makes me wonder how that might affect
waking back up into full functionality *sometimes*.

That's on a desktop PC box. I don't know if SWAP's role plays a part,
but the inconsistencies I'm seeing reflected in mine felt worth
mentioning... :)

Problema resuelto Ricardo  :)

Aunque me gustar'ia saber qu'e hace en particular cada una de esas
directivas pues me cambi'o otros comportamientos, por ejemplo, durante  
el
arranque no me mostraba los detalles del proceso de inicio en la  
consola y

ahora s'i, pero bueno agregu'e varios par'ametros.


Perdona copie la configuración que tengo en mi maquina le única  
directiva que tienes que agregar para


los nombres de interfaces es net.ifnames=0

Estas directivas "acpi=on numa=on iommu=pt" las tengo en mi maquina por  
que testeo sistemas de virtualización con XEN y KVM


y en algunos casos es necesario generalmente para uso estandar no hacen  
falta.


Ok, pero... por ejemplo, a mi gusta eso de que te muestre todo lo que va  
haciendo durante el inicio y en versiones anteriores yo lo hacia  
descativando el modo grafico por defecto, as'i que una vez logueado, aun  
los usuarios comunes debian levantar el grafico con startx.


De todas esas cu'al es la que logra eso?





Tambi'en quisiera resolver este problema de los acentos pues hasta la
versi'on 7 yo lo hac'ia con una sencilla modificaci'on en la variable
XKBLAYOT="us_intl" pero ahora solo me result'o para la consola en modo
texto pero para las consolas en X y en el gedit sigue igual.


Yo lo que hago es instalar el paquete locales-all y luego ejecuto

dpkg-reconfigure locales

Primero elijo "Todas las configuraciones regionales"

y luego selecciono es_AR.UTF-8 ( por que estoy en argentina )

Luego hay que desloguearse y volverse a loguear para que los cambios se  
hagan efectivos.

Perhaps you need to investigate syndaemon. This disables the Synaptics
touchpad whenever a key is struck. The disabled period is configurable,
so if I type
$ syndaemon -i 1
into any old Xterm, the cursor will be dead for one second after any
key is struck. You can set it up in the background with   -d   and
put it in .xsession or equivalent.

The only downside is if you're adept at two-handed work with cursor
and keystrokes, but bear in mind that any attached mouse is unaffected.

Cheers,
David.

los nombres de interfaces es net.ifnames=0

Estas directivas "acpi=on numa=on iommu=pt" las tengo en mi maquina por que

If we are talking LaTeX now, does anyone have
a "MWE" as they like to say?

It absolutely doesn't have to be CAD by any
standard other than the ability to draw simple
geometrical objects and have them denoted

Dans la mesure où fr-oss est disponible dans plusieurs, sinon toutes les

Strange. I tend to take the most appropriate for
the job (if I'm going to chop wood every winter,
I try to get one which is durable). But I usually
don't look at the price as long as it is roughly
whithin budget. It's not the label I'm after (and
yes, the price is just part of the label, as you
can see in Apple products, but also Gucci, whatever).

This is something I wanted for years. But it
has to be real-time so the moment you evaluate
(plot-pixel 0 0 "red") a red dot appears in
the top-left corner of the screen (can be
a separate window). Perhaps this can be done
with SLIME and SDL, I don't know.

I crosspost this to gmane.emacs.help .

Here, does "professional" denote some quality
with the software or is it about who uses it
and how?

Because when I chop firewood, I do it with the
most expansive axe in the hardware store.
While this doesn't make me a professional, if
it was too difficult for mere mortals to
handle, there wouldn't be a hardware store to
begin with. Or at least it would be the size of
a spacy apartment and not a stadium.

So as for me, I don't really care how other
people use the software as long as it is there
for me, professional or not.

The question is... what is useful for us all, not only for *you* or
*me*?

More and more, not gaining control over your software means your
vendor gains control over you (cf. the stampede to the cloud, apps,
many vendor's move to pay-per-use and subscription models, etc. etc.)

To have a remote chance of having a say on this, we "consumers"
have to bundle forces.

No, I don't want to be reduced to a gullet.

I would think precisely the opposite. Gaining control over the software
you use will prove really useful only when you are planning to use it
for a long time. As an example, I would imagine that a serious person
might require a very specific functionality from the software, then they
could just write the code to achive this function.

Check out Varicad (.com) too, its is propriatary but you can try it for
free.
