VPN stands for virtual private network. The virtual means that this privacy is accomplished allthough it is by nature not private at all when you communicate over a public network - the internet....

in short, vpn clients all do more or less the same - just not in the same speed. They allow you to securely / encrypted connect to a destination - in your case your company, so that your network...

Do you have the command that does it (once)?
Then you can put it into crontab with an appropriate schedule.
Read about the crontab with
man crontab

The trivial answer that can be read (almost) everywhere: in a safe place. But, that's not as trivial as it reads. While you can - during creation - have the backup archive on a local disk /...

What do you actually mean by "the network' ?

You should be very specific when discussing technology if you really want help.

But in general, where you store your backups is based on your risk...

I'd start with find /lib* /usr/lib* -iname '*qt*.so*'

Faling that, ldd some-program-that-uses-qt

If not knowing the host (which identifies itself with some sort of key similar to the ssh key during login negotiation), the client informs you accordingly and asks you if you really want to continue...

For Ubuntu, you can read the source code directly yourself.

For example, you can pull it down and search it using, like so:

apt-get source linux-source-3.2.0

or, you can go to the Ubuntu...

When the target-servers target-users $HOME/.ssh/authorized_keys does not contain your key (from /home/rob/Work/Keys/keys.txt.pub), it's absolutely clear why key-based auth does not work:

Because...

Hi,

authorized_keys does not contain private keys. It only contains public keys. The private key should not leave the source system.

You can check what's really going on by increasing...

The two large files are functionally equivalent, using different methods of compression.

The two small ones are just checksums for the big ones.

find myDirToStartWith -type f | xargs grep 'this string'
Starting at directory 'myDirToStartWith' find recursively all the files of type file.
"pipe" (|) all the output of find as input to xargs...

The /sys/ is an interface to the kernel (that resides in memory). A device driver, when loaded by the kernel, can plug into the /sys/ tree.
It depends on the driver how this is done. For example it...

I'd change your code slightly:

void amplifierUnmute()
{
std::ofstream amp(amplifierGPIO);
if (amp.is_open()) amp << "1" << endl;
} I'm not completely sure the newline...

It seems you need to understand a few basics about UNIX/Linux filesystems before we can tackle your problem:

A "filesystem" in UNIX is a space where files can be stored. It is organised in a way...

Have you considered doing a stack trace to hunt down the timing issue for this?

What system are you working on and what is the C++ compiler you are using, etc?

I think you should ask, and get them to explain why certain things are true/useful/shouldn't be done or whatever to make them justify the senior tag - and pay. If they are no better than yourself,...

Ask a real question. Think about some point where you got stuck, and ask the person what he/she would do if you came to them with the problem.
You will learn about their approach to...

Interviewing is quite simple.




Show genuine interest in the candidate, their family, education, experience and favorite projects. You can use their resume to help you if they are not...

So, no init system or anything? Your terminal probably hasn't been set up. This is a surprisingly tricky bit of "magic" done with a special syscall which we're for the most part happy to let some...

You probably want to see/verify your current terminal configuration.
echo $TERM
will display this

Now, I am not sure whether that error message is telling you that you ARE using VT100, or that...

That was a very commendable idea. Now let us go over the script. First, its "big structure":


#!/bin/sh
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/entity/bin //designate the various path's...

Yes, exactly. You could write a script using the mv, cp, rm, etc.programs, which are all located in /usr/bin (or /bin, depending on your system) by every time specifying the complete path to them. (I...

No. In fact it is a "variable". Suppose the following: i don't know where you installed a certain program, but i know how the place where the program is installed looks like because i work with it a...

Hi,

It is quite common to change the order of the PATH directories, as an example on Solaris you may want to pick up a different version of a binary - for instance the posix compliant version of...
