Sounds like your demands were pretty easy to satisfy, much more so than I had
initially thought. But thanks for triggering the discussion.

rhayman's 4U storage servers (which appear to be for sale) are at about $4k
new without drives; a very different scale of things.

I do like RM solutions? I have a Norco case that drives the d3photo empire? beyond that? not so needy. Yet. 

I have a new life that starts on Wednesday with the great minnesota get-together that might change my mind on things.

It looks there are a lot of people interested in the topic, but
they haven't had a meeting yet.  They lack a place to meet

The last time I did this, it was on a SuSE box, but the proceedure I doco'ed
at the time is:

Install the x11vnc package.

The basic usage of x11vnc is to run this command on the machine you want
to serve up the display from:

x11vnc -display :0

This will 'screen scrape' the desktop and allow anyone to connect to the
virtual display provided by VNC and thereby control the desktop.
However, there's no password on this.

To set up a password, run this command (as the user who owns the
desktop, of course):

x11vnc -storepasswd 

This will create a ~/.vnc/passwd file which contains a hash of the
password you entered.

To use that password to require authentication to the VNC session, use
this command when starting x11vnc:

x11vnc -usepw -display :0

It should be noted that while this at least requires a password for
authentication, it does *not* encrypt the connection. To get that we
would use the -ssl option, like so:

x11vnc -usepw -ssl -display :0

Or else wrap the connection in an SSH tunnel.
The advantage of an SSH tunnel is that it can apply some compression to
the stream, which may be desireable over slow links.

An SSH tunnel would be set up with a command similar to this:

ssh -L 5900:localhost:5900 user at host.example.tld "x11vnc -usepw
-ssl -display :0"

This would log into the 'user' account on host.example.tld, set up
a tunnel from port 5900 on host.example.tld to port 5900 on the host
originating this command (i.e. your desktop). In order to use this, you
would point your VNC client to localhost:5900 or localhost:0

It is possible to script the above, and probably launch a VNC viewer at
the same time to connect to that host. This will require a little more
time to hash out the details of, but an example script is to be found here:

(Responding to Carl but not quoting his message for brevity.)

Regarding SuSE, I am sitting at a SuSE box with a pretty late build:
Linux _____ 3.16.7-35-default #1 SMP Sun Feb 7 17:32:21 UTC 2016 (832c776) x86_64 x86_64 x86_64 GNU/Linux

It does have (Tiger)Vnc,  but not the x11vnc package. I did not know that x11vnc
does a "screen scrape" to the X server without having hooks into privileged
user space (which it may well have). Up to a few years ago, the VNC that was
shipped for use with the Xserver had to have an X server module loaded in
the X11R6 or Xorg conf file (called "vnc") that allowed for this functionality.

In the same box I looked and found this:
/etc/X11/xorg.conf.d/10-libvnc.conf
It has the vnx module as a loadable option; looks like this:

#Section "Module"
#    Load "vnc"
#EndSection

What I am suggesting to Mr Coleman is to see if there is a vnc module in his
Ubuntu X server installation. Use that first if you can. This does not involve
Xvnc, etc, which is what you are probably using (you did not provide details).


A user can scrape the screen if they own the display, and I wrote a code that
does exactly that (I call it "Xleach"). If you want it, email me.


My Slackware systems use a different setup:

/usr/lib64/libvncclient.so.0.0.0
/usr/lib64/libvncserver.so.0.0.0
/usr/lib64/libvncclient.so.0

/usr/bin/SDLvncviewer
/usr/bin/libvncserver-config
/var/log/packages/libvncserver-0.9.9-x86_64-2

If you are an Ubuntu user, you probably do not want to go there.

I have not played with Runge's x11vnc that Carl suggested, but it looks like a
simple a solid solution of the bare-bones type that I like.

I hope all this stuff is helpful to you.

I never have used tmux, but for what it is worth you may want to look into
their mailing list or FAQ. See if tmux starts process with "NOHUP" states or
something like that.

i've had a chance to poke at it a bit now, all the simplified test
functions i try all *do* exit with their parent window, even tho i include
many of the structural elements of the full function.  the full function
however does not exit with the window.  dunno why, tho it doesn't really
matter..  to answer my own question:

[ -t 1 ]

nicely tests if the parent terminal still exists, or, since the function
invokes "less", i can simply use the abnormal exit from less as an
indication the terminal is gone.

FYI

As a general rule, closing a terminal window will send a SIGTERM signal to the shell, and close resources controled by the window.  e.g. stdin, 
stdout, stderr, /dev/pts/... etc...  So your child process will usually either catch the SIGTERM, or detect that it's /proc/self/fd/* references 
have been closed and terminate itself.  But there are some cases where the child process ignores signals and doesn't check the status on it's 
resources.  So it closed stdin itself and no longer listens for input, or only accesses stdout/stderr if needed.  In those cases the child 
process could run until it attempts to access those resources and terminates with an error accessing them in the future.

An example of this that I use is a backgrounded ssh port forward:  "ssh -L 1234:target.host:22 -N pivot.host &"
I've had these last though complete logouts, which I like, until I really want it to terminate and need to run netstat -lnp to find it again.

Hope that clears things up a little.

Thanks for this info. you are saying processes will terminate if trying to
write to stdout, but would otherwise stay alive if signals were set to be
ignored, correct?

The last part, about finding them and terminating them, you are looking for the
PID that is attached to the socket. I think for your purpose this would work
best: 'ps axu | grep ssh | grep 1234'

But I see your point.

As a side note, I have not had much luck with non-executing ssh tunnels (-N)
staying alive in most cases. I should also say, I am mostly using reverse
tunnels (-R).

Message-ID: <060b01d2cffb$183e1b30$48ba5190$@trecksolutions.com>

Hello,

 

I hope this is the appropriate place to post this?

 

Looking for a DevOps Engineer(heavier on the Ops side) w/ Chef exp.
Java/Linux environment,  FTE, West Metro/work Remote option.

 

There are 4-5 developers that basically work for the managed services group
doing remote monitoring for their customers. It's a blend of Dev Ops.  More
Ops than Dev.

Must have Chef experience - configuration and automation tool, writing and
maintaining recipes, cookbooks.

would like to have someone that has at least 1 year experience with Chef and
monitoring experience

Next would be to find someone that has monitoring experience - he's looking
for someone that can figure out what issues might be, not just seeing if
something is up or down

Most of their stuff is Java on Linux (this is a nice to have)

They use OSGI to deploy Java - if someone has Spring experience they can
figure it out pretty easily

They use Maven for PM

Redhat

If someone had virtualization with KVM - nice to have

 

If interested, or know anyone, please send a Word resume and lets chat.

 

Thank you!

if the listener is gone the write will return an error, but whether the
error causes the process to terminate is still up to the process.

We're going to be getting new laptop computers in the near future.  My
wife has been happily running Peppermint 3.0 for a couple of years,
and wants to continue running Linux.

We installed Peppermint because it would load and run on the old Dell
Latitude we inherited.  (Thanks, Josh! It's been a workhorse - it just
can't keep up with what she wants to do on the web nowadays.)  The new
laptop will be significantly more powerful.  Any recommendations on
distros to consider instead of just going straight to Peppermint 7?

My only recommendation is to drop a tarballed or dd-ed image of what she has
now right on to the new computer (tweak the boot-sector, etc, so that it boots)
and see how the old OS holds up.

This way she will feel no change and potential (mis-configuration) glitches
from the migration.

I am a bit old-school and conservative if not careful with making changes.

Do the research.
Choose the distro then the laptop that has compatibility or choose the
laptop and research which distro has all the right drivers to make it
all work on install.
Gone are the days of picking a laptop and dropping your preferred
distro on it and everything just works.
For example
Qualcomm atheros (AKA Killer) wifi cards have more issues than Intel
cards - actually connecting and staying connected to lower throughput
speed.
What graphics card/architecture (AMD/NVidia/Intel)? Onboard Intel
graphics has better battery life.?
Internal/External monitor resolution to be used? FHD?, 3K?, 4K? You may
or may not need the power of separate graphics card.
Laptop slots? some models have more traditional connectors (USB-2, HDMI
1.2, SD card, 3.5mm headphone) and some don't?
Docking station? Some smart docking stations do not play well with
Linux.
Sometimes your choice to use a LTS version is hampered by not being
able to support your new hardware, sometimes your choice to not use a
LTS version breaks your ability to keep using certain hardware e.g.
AMD?dropping support for proprietary AMD driver in favor of encouraging
users to use the open-source AMDGPU/Radeon drivers so your distro
upgrade removes working drivers. Unfortunately the open-source drivers
do not support all functionality that the proprietary drivers did.
I first installed Linux (RedHat 2.1 CD, kernel 1.2) on a new Compaq
laptop and have used Dells, Macbook Pros, and Thinkpad hardware with
one distro or another ever since. I'm currently running Ubuntu 16.04.2
LTS on a 4K UHD Dell XPS-15 9560 (2017) and the Dell USB-3C/TB dock
will power the laptop but the ethernet port doesn't work, nor do many
of the other ports.

In the past Thinkpads have been known to run Linux well. I've used them for many years.   Now it seems Lenovo is moving on to other products so I don't know if they have kept up with Linux stuff. 

 I agree with rhayman, do your research.

This wiki could be useful info on Thinkpad options:
