 This is the FUD of the year.

 scratches slightly on a chutzpah...
 ...sigh!



Sigh.  No, it's not FUD.  It's over 20 years of system and network
administration running big iron network servers, from file servers, to web
servers to mail servers and so on.

Developers tend to look at the WOW, look what I can do! side of the
house, while us system administrators must live in the real world and pick
up the pieces from the WOW projects.

The US Navy is where I work now.  I've also worked out in the civilian
world doing the same thing.

There are plenty of instances in the last few months alone of web sites
from supposedly secure installations being hacked.  Does the name Target
ring a bell?

You can do what you want with your machines and your network.  For me, I'll
leave the server stuff on the servers, and the work machines running the
minimum of software necessary for the task.

 I do have such a setup out in the shop building, and have had a fully

 too short piece of cat5 from the hub to a teeny little table the lappy

 the machine controllers.

 At any one time, I have one of those pocket wifi sniffers that can see a
 half a dozen similar routers scattered about my neighborhood.  In 5 or 6
 years, I have had one outside signal come into the system and go on out on
 the internet, apparently uninterested or un-aware of the extent of my local
 network. No clue if he was watching porn or what, but I reached into the
 router and disabled the radio, then setup a WPA2/AES login with a loong
 passphrase, and have had no further trouble.  However, trying to get that
 same security model setup in the Mint14 that is currently on the lappy, I
 am back to using the short cat5, stretched across the front of the machines
 and definitely in harms way.

 I understand Mint16 is out now, and maybe it has a smarter wpa_supplicant
 that can do that security, because the cable really is a PIMA.

 So, my one breakin was benign in its effect on me other than hogging some
 bandwidth.



Gene,

Security by obscurity was once a valid technique.  Still may be effective
if you live way out in the sticks.

However, anybody with a car, a laptop, and a wireless network sniffer can
latch on to a wireless network that's either unprotected, or lightly
protected.

My machine controller is hardwired into a full copper network.  Someone
trying to get into the machine must first breach two firewalls, one on the
router and one inside the network, and networking must be turned on the
machine controller in order for someone to get even a chance at running a
port mapper against it.

Maybe I'm being paranoid, but I watch attack attempts from all over the
world at work on a daily basis run against blocks of addresses.  You're not
really paranoid if they are out to get ya...  ;-)

Jon,

You're describing TCP Wrappers to a tee.

Use hosts.deny and put ALL : ALL in it, then use hosts.allow and allow only
the machines you want and what services you want those machines to have
access to.

Of course, this does require the service be wrapped.

 Please undeceive me.
 What is on a http server per se unsecure ?
 No matter if it is coded in python, javascript, c/c++ or what ever.

 BTW, telnet is a remote shell.
 It has been made for executing commands on a remote computer.

 Matsche



Every web server uses ports and sockets that are open to the world if
placed on a network, which is the obvious point in running a web server.
There are various ways of attacking those ports and sockets to gain access
to the underlying system.  It doesn't matter what it's coded in, though in
some cases, with poor coding, it may be less secure.

Telnet is not a remote shell.  Telnet is a network application the
transmits and receives IP packets in clear text and connects to a network
service on a remote host.  You can telnet to any open port on a remote
machine, and talk to that port.

 It depends on your needs for access to the machine.  I have
 an e-mail
 server (smtp), an ssh server, web server and primary DNS server
 on the machine.  I may need to log in via ssh from odd locations
 from time to time.  So, I need to have a number of ports open,
 yet still be secure.  This has been running for several
 years with
 no successful attack.  Very few people even try anymore.

This works well and is an excellent example and could be useful as is

One thing that differed from your instructions was that this line:

sudo apt-get install setuptools   did not work as no package was found

However it appeared that the previous command:  sudo apt-get install

I ran it on the local PC browser that already had LinuxCNC installed

I pointed a Nexus 7 tablet running firefox at the LinuxCNC PC and the

No, networking is not the worst thing in the world.  Please don't engage in
hyperbole.  I'm talking about stuff that I deal with on a day-to-day
basis.  If you want to run the risk, that's fine with me.  It's your
machine, do what you wish with it.

My machine controller is just that.  A machine controller.  Not a web
server, not a mail server, not a internet browsing machine, just a machine
controller.  My CAD software, my email client, my web browser, my chat
client and everything else resides on a different machine.  This one, the
one I'm typing this post.  If you want to run all that stuff on your
machine controller, and are ready to accept the risks inherent in doing
that, then go right ahead.  I'm just offering my opinion based on years of
network and system administration experience.

At work, we don't even combine web and mail servers.  Each does it's own
thing, and each is locked down to the minimum necessary for those
individual services that need to run in order for the machine to function
in it's role.

 Gene,
 
 Security by obscurity was once a valid technique.  Still may be
 effective if you live way out in the sticks.
 
 However, anybody with a car, a laptop, and a wireless network sniffer
 can latch on to a wireless network that's either unprotected, or
 lightly protected.
 
 My machine controller is hardwired into a full copper network.  Someone
 trying to get into the machine must first breach two firewalls, one on
 the router and one inside the network, and networking must be turned on
 the machine controller in order for someone to get even a chance at
 running a port mapper against it.
 
 Maybe I'm being paranoid, but I watch attack attempts from all over the
 world at work on a daily basis run against blocks of addresses.  You're
 not really paranoid if they are out to get ya...  ;-)
 
 Mark

Snirk, but Mark, as far as fancy hackers go, I really am out in the 
sticks.

FWIW, I run awstats on my web server, and am somewhat puzzled as in any one 
month, I might have 3 or 4 megabytes pulled, and 40% of it goes to Chinese 
domains.  Why?  I also have a subdir with 2nd amendment related stuffs...

Hey, we all have to do our part don't we?

Cheers, Gene

The majority of the attacks we see come from China.  Followed by Russia,
and other Eastern Block countries like Bulgaria.  But far and away the
largest number of attacks are Chinese initiated.  I see it here too on my

I am on the 2.5.3 branch ATM, and I usually do the updates as soon as 
update-manager tells me they are available.  And nothing in any update has 
had a detectable regression effect on my machines since I switched back to 
the 2.5.3 branch.  Updates have slowed the last month or so as everybody is 
working on the next release to be called 2.6.0, but I have probably 
installed about 75 updates to linuxCNC in the past calendar year without 
encountering a problem worth noting.  They just work(TM).  :)

YMMV of coarse.

One thing I have noticed - with the new TP - the path reaches commanded 
speed.  mach gets close but is usually a few percent under.

Take this program steve posted a while back.  ( 
http://electronicsam.com/images/KandT/testing/steve.ngc )

New TP
http://imagebin.org/296859
If you calculate it out - it is about 3600mm/min.  that is the commanded 
velocity  (following path within .1mm aprox .004)   it actually 
finishes a whole .5 seconds faster ;)

With Mach
http://imagebin.org/296858
it peaks at about 3300mm/min.

Have you tried the new tp with g41/g42? Im sure it wont matter but just in
case...

Terry
One thing I have noticed - with the new TP - the path reaches commanded
speed.  mach gets close but is usually a few percent under.

Take this program steve posted a while back.  (
http://electronicsam.com/images/KandT/testing/steve.ngc )

New TP
http://imagebin.org/296859
If you calculate it out - it is about 3600mm/min.  that is the commanded
velocity  (following path within .1mm aprox .004)   it actually
finishes a whole .5 seconds faster ;)

With Mach
http://imagebin.org/296858
it peaks at about 3300mm/min.

 Here is your sample of gcode running the newest TP

 Hi Chris - Here's part of the code - it's obvious early on without all
 of it. I'll post the config tomorrow - machine is at work.

 BTW - Changing N190 to

 N190 G64 P0.5

 and it runs better, but that's far too much deviation.

Terry, that's a good idea. I suspect G41/G42 won't affect much since the
offsets are applied before the path is sent to the motion module, but it
would be nice to be sure.  Do you have a program handy that use G41/42
extensively? If so, I'd be happy to add it to the tests I run.

This is the 45deg tool to break the edge but
still roughly the same code as the end mill code.
You will have to change the feedrate to really test

does.

 Terry, that's a good idea. I suspect G41/G42 won't affect much since the
 offsets are applied before the path is sent to the motion module, but it
 would be nice to be sure.  Do you have a program handy that use G41/42
 extensively? If so, I'd be happy to add it to the tests I run.

  One thing I have noticed - with the new TP - the path reaches commanded
  speed.  mach gets close but is usually a few percent under.
 
  Take this program steve posted a while back.  (
  http://electronicsam.com/images/KandT/testing/steve.ngc )
 
  New TP
  http://imagebin.org/296859
  If you calculate it out - it is about 3600mm/min.  that is the commanded
  velocity  (following path within .1mm aprox .004)   it actually
  finishes a whole .5 seconds faster ;)
 
  With Mach
  http://imagebin.org/296858
  it peaks at about 3300mm/min.

Sorry I changed from the 65ipm to 100 before I sent it
I usually run that operation at 65 to get the surface finish
I may need more spindle speed with the new tp :)

 I had a copy on an old stick.
 T4  dia is .05 in the tool table
 This is the 45deg tool to break the edge but
 still roughly the same code as the end mill code.
 You will have to change the feedrate to really test
 the speed as this feedrate works fine with old tp(at least on my VMC it
 does.
 I use v 2.5.0
