Simplest and Effective way to Take Screenshot in Linux

2018-02-13T23:19:57Z

Linux is a powerful and diverse operating system and as a result of that, naturally the screenshot tools for the platform are just as powerful and diverse. The different types of these screenshot tools available range from simple and easy-to-use to powerful command-line tools that offer the ability to script that automate the process. Screenshot is an image taken by a computer to capture the visible items on the monitor or any other output devices. There are several ways of taking screenshots in Linux but I will limit the discussion to one of the simplest and commonest means of taking screenshots in Linux thus using gnome-screenshot.

Use gnome-screenshot

The first most important way of taking screenshots in Linux is by using Tools that can give flexibility with respect to editing the captured screenshot among other benefits. When one is looking for a tool in Linux to do such a job, the Gnome-screenshot comes into play. Gnome-screenshot utility is part of the GNOME Desktop Environment, which can also be used to take screenshot. It also has a command line mode (gnome-screenshot)
Use gnome-screenshot Command line
This utility has much more features as well as flexibility when taking screenshots and is included in some linux distributions by default. However if your linux operating system does not come pre-installed the here is how to install it.

Can a processes survive after shutdown?

2016-01-27T11:02:40Z

I had a process in a "uninterruptible sleep" state. Trying to kill it is, unsurprisingly, unhelpful. All the literature on the subject will say that it cannot be killed, and they're right. It's called "uninterruptible" for a reason. An uninterruptable process is in a system call that cannot be interrupted by a signal (such as a SIGKILL, SIGTERM etc).

These typically arise when the kernel needs to do something that could take "a while", and that certainly was the case in this particular situation (a user filled a disk partition and NFS lost its head, but that's for another post). Uniterruptible sleeps are actually very useful; they're needed when a process reads/writes to disk for example.

Get the hell off Apache OpenOffice, it’s insecure & not worked on any more. Go to LibreOffice.

2015-09-17T23:43:11Z

Originally posted by reddragdiva at Get the hell off Apache OpenOffice, it’s insecure & not worked on any more. Go to LibreOffice.

you know OpenOffice, right? free substitute for Microsoft Office which is basically just as good, but free.

well, it's not as good. and is in fact actively dangerous to use.

the security hole: HWP files can be exploited and pwn your PC. obscure minor format, no problem ... except that if you get a HWP file with a .DOC extension - say, what appears to be a MS Word file emailed you by anyone - you can get pwned by that.

they've known about this since april 2015 and haven't fixed it. they have distributed over 8 million known-vulnerable copies of AOO since 27 april. (and the 143 million vulnerable before that.)

the fix is, literally, remove one file from the installer. they haven't got it together to do this in five months.

tell everyone you know. tell your writer friends. tell anyone you see running OpenOffice. get LibreOffice, it also originated in OpenOffice but is actually developed and they show the slightest sign of caring about their end users. LO 5.0 is really very nice. much faster to use than 4.4 too.

so what's going on here:

Sun Microsystems (mild yay) ran OpenOffice from 2000 to 2010. it was imperfect, but it was good enough and free and open-source. it accumulated one heck of a famous brand name. (“we need an office program” “how about that openoffice thing”)
Oracle (boo hiss!) bought Sun in early 2010. OpenOffice development stopped as they reassigned developers.
a bunch of non-Sun/Oracle developers went "bugger this" and forked it ('cos it was open source) in late 2010. thus, LibreOffice, which immediately became stupidly better.
Oracle had a snit and shoved the corpse of OpenOffice at the Apache Foundation in mid-2011 at the behest of IBM, who wanted to do it their way.
Apache OpenOffice had nothing worth the trouble, but got downloads because of the famous "OpenOffice" brand name.
IBM gave up in late 2013. since then, AOO has literally been sixteen ex-Sun devs squatting the name and doing bugger-all with it. their reasons are unclear.
they insist they still have a product, even though what they've actually achieved has been to put over eight million downloads that they knew were vulnerable on people's PCs. possibly your PC.
instead of fixing it, by removing one file from the installer, they post excuses for not doing stuff.

(if this sounds like a fascinating tale, feel free to check the extensively-cited history sections of the OpenOffice.org, LibreOffice and Apache OpenOffice articles on wikipedia, which i mostly researched and wrote.)

Apache OpenOffice's lack of developers since IBM gave up is extensively documented. many have expressed concerns over the BLATANT SECURITY HOLE. in late august a Red Hat developer posted an open letter urging them to just give up the pretense and redirect the end users (that's you) to LibreOffice. this had wide impact, and quite a pile of others concurred that they need to stop making life actively worse for the end users. the AOO people posted numerous comments making excuses ... but they still distribute their known dangerous software and just won't lift a finger to fix it.

tl;dr: get the hell off OpenOffice, get everyone you know the hell off OpenOffice. get LibreOffice, it is strictly superior in literally every dimension, and they actually give a damn about you the user and fix the security holes.

http://grey-olli.livejournal.com/782450.html (открытое письмо к провайдерам интернет в Москве [по мере получения комментариев пост будет обновляться]

Речь там идёт об услугах ценных, на мой взгляд, для гиков, врпрочем не только.

Хотел бы узнать Ваше мнение - насколько актуальны для Вас как IT специалистов те услуги, о которых я пишу как "killer feature" с моей точки зрения.

По возможности, просьба откоментировать у меня, врочем если Вам проще ответить тут - Ваше мнение я всё равно постараюсь отразить в своём открытом письме.

Там в том числе и про linux, хоть и совсем чуть-чуть, так что это не совсемм offtopic. ;)

Is it possible to dynamically add a new back-end server to pound without restarting pound?

2014-11-12T00:07:26Z

Anyone else use pound load balancer? I like it... but from my reading I can't find how to dynamically add a new back-end server without completely restarting pound ... which means downtime.

Linux Challenge Question of the Day

2013-08-08T17:26:41Z

Very often I'll set a environment variable before running a command.

For example,
$ sudo JAVA_HOME=/usr/java/default /usr/local/activemq/default/bin/activemq-admin query -QQueue="my.activemq.queue.whatever"

But I've noticed that if I set a variable and then call echo to show that variable echo returns nothing.
$ FOO=bar echo $FOO

(nothing was returned)

But I can export the variable and then call echo and it works:
$ export FOO=bar ; echo $FOO
bar

Or if I set the varaible and then call "env" to check it I see the environment variable is set:
$ LALA=FUN env |grep LALA
LALA=FUN

So why can't I set the variable and then check it with echo like in the first example above?

Update:

I got my answer on facebook from Douglas Kilpatrick who wrote: because variable substitution is done before command parsing. So when the command gets run, it's already "FOO=bar echo ''"

Solution (provided by Douglas Kilpatrick):
$ FOO=baz eval 'echo $FOO'
baz

How to log into a host via ssh and completely ignore host keys.

How to log into a host via ssh and completely ignore host keys.

[jackal@brads-mac]# ssh -o LogLevel=quiet -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no www.somehost.com date
Thu Jun 6 15:32:55 UTC 2013

How cool is that?

Completely ignores host keys. So you'll never see an error like this again:

[jackal@brads-mac]# ssh www.somehost.com
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
90:9c:46:ab:03:1d:30:2c:5c:87:c5:c7:d9:13:5d:75.
Please contact your system administrator.
Add correct host key in /home/user/.ssh/known_hosts to get rid of this message.
Offending key in /home/user/.ssh/known_hosts:1
Password authentication is disabled to avoid man-in-the-middle attacks.
Agent forwarding is disabled to avoid man-in-the-middle attacks.
X11 forwarding is disabled to avoid man-in-the-middle attacks.
Permission denied (publickey,password,keyboard-interactive).
$

Now to make it permanent: Add the following lines to the beginning of the SSH configuration file (~/.ssh/config).

Host *.somehost.com
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null
  LogLevel=quiet

You can ever remove your ~/.ssh/known_hosts file as it will no longer be needed or read anymore.

X11 gui programming - suggestions please

2012-10-27T00:03:05Z

Greets
 
I am working on a hobbyist project to generate a coded text file based on
user input.
 
I am using C++, and MVC design pattern(s). Have decided it will be licensed GPL v3.
 
For the GUI (view the user will interact with) I am researching gtk,
curses, and such, but never have used any of them before on a project.
 
Hoping my fellow Linux grp LJers might have ideas/suggestions based on your
experience doing GUI programming.
 
I dont' think I will need to draw graphics or images. At this stage I
expect my GUI would just need to view/display/intake keyboard text.


Btw, I asked my SGVLUGers, and Debian LJers, have the following as suggestions so far (in no particular order):

ncurses
qt
gtk + glade
fltk
jx

netstat -L from freebsd under Linux

2012-09-26T03:44:19Z

Is there a way to view queue length on listening socket under linux, the same way as netstat -L outputs for freebsd? I.e. you can see X/Y/Z in netstat -L output, but netstat under linux doesn't support -L flag.

upd: ss -l shows reqired Recv-Q Send-Q

linux & ssd

2012-02-28T13:41:25Z

Dear Ubuntu Users,

Lately i did some research on what you should or could do in linux if your computer has one of those 'fancy' solid state disks. I found a lot of howto's and technical stuff.
Next step will be to filter the "stuff" and write down how and what i did, to (hopefully) tell Ubuntu on how
to communicate in a more 'friendly' way with sammy's ssd ;)
Note: sammy = Samsung NC10 netbook

Stay tuned, more to come soon!

I'm all ears and eyes for your comments, questions, opinions, whatever you want to say/know ;)

[This is a crosspost from my journal. Please comment in my journal only, that will be easier for me to manage ;) Thank you!]

Friendly Greetings, Guen
