Ubuntu :: Child Protection / Net Nanny Type Software
Jun 11, 2010
I have a desktop with Ubuntu on it that will be used by children for internet access and the parents of those who will be using it would like that some sort of basic child protection software was installed on it so that those using the computer don't accidentally or even deliberately out of curiosity access adult material.Is there a decent easy to use Ubuntu software out there that allows for parental control over what kind of websites can be accessed by children?

I've enjoyed my time with Ubuntu and want to share it with my family.
My son is still quite young and I want him to have a positive experience on the net.
Is there any kind of net nanny type program for Ubuntu that I can load on his computer for his protection?

I am fairly new to c++. There must be a better way to do the following?:- Say I have a base class, Pet. I have several child classes that extend from this, like Dog, Cat, Fish etc.
I have the following function, that returns a pointer to a new Pet:-
Code: Pet* addPetToVet()
{ //Do some stuff
return new Pet();
} This will return a pointer an instance of a pet object.
Now, if I want to interpret this pet as a dog or cat I have to do this:-
Code: Dog* dogA = static_cast<Dog*>(addPetToVet());
Cat* catA = static_cast<Cat*>(addPetToVet()); Is there a way around this? Casting seems lame. I cant write a function for each type of pet.

I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>
[code]....

I am troubleshooting something and I got this problem.
If I do "pstree -p"
It shows,
Code:
[code]....
However, it does NOT show up in "ps -elf"
Code:
ps -elf | grep soffi
0 S whho 7734 1 0 80 0 - 36435 - 11:14 pts/2 00:00:03 /usr/lib/openoffice/program/soffice.bin -splash-pipe=5
0 S whho 7833 7759 0 80 0 - 751 - 11:21 pts/3 00:00:00 grep soffi
I was wondering if 7735, 7736, 7737, 7743 were really processes. Then I checked /proc, I could cd to /proc/7735, /proc/7736, etc, but I could not ls them out. I looked at the man page of "pstree", it says,
Code:
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.
icecast2---13*[{icecast2}]
So, what does all this mean? Does it mean that 7735, 7736, 7737, 7743 are just threads but not processes? If so, why could I cd to /proc/<id> but not see them in "ps -elf".

Consider the following code:
Code:
int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)
[code]....
I get the following output:
Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1
[code]....
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?

I'm trying to install Gnome Nanny [url]
I installed it using Synaptic and when I restart, the Nanny daemon appears to be working.
However, when I try to access to the Parental Control (System - Administration - Parental Control) and after writing my password, it does not shown anything. Nor any windows not any configuration.
I am using Lucid Lynx I386.
Do you know any parental control which could block programs execution (like games, instant messengers, browsers...), could have web filtering and could have spending time control?

I use the Ubuntu 10.10 netbook remix. To limit the time of kids using the netbook I installed Nanny and set the timelimit to 0,5 h.
But for some reason it doesn't work. You can see the Nanny Icon, but it isn't logging of the user when the timelimit is reached...
Did anyone encounter the same problem or is it just me who did something wrong?

I have dowmloaded the latest version of Gnome Nanny, but have run into an instal problem at the first hurdle:
I have extracte the folder to Documents: Cd/ to the folder and run the ./configure command and get this message: No package 'pygtk-2.0' found
I have checked the install files and edited the lines which contain the above to now read pygtk -2.0 >=2.8 as 2.8 is the version of python I have installed. In package manager it only goes back to v2.2.
How I can get around this error?
Running Ubuntu 9.1 karmic Koala.

I installed Gnome Nanny. I can choose the times when the computer can be used and limit the internet. However, these times are not being enforced. Is there some other settings that are used to enforce these settings?

I have difficulty in running Gnome Nanny in Lubuntu 10.04. Installation is easy just by adding repository and do sudo apt-get install. But clicking on "Parental Control" resulting in nothing and I do not know how to change the setting for example, email only and no browing?
I think Gnome Nanny is user friendly and suit my purpose to stop user access to browser internet but email only through zimbra.

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive

I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.
octave:2> test1.m
error: can't perform indexing operations for <unknown type> type
sh: gnuplot: not found
Just to double check my work, I ran the following code:
y=[1 2 3];
plot(y);

Is there an app for Ubuntu, or can you show me how to write a PHP, Perl, or Python script, that lets me record a webcam screenshot every 15 minutes and upload it to my Dropbox account (or FTP location)? Of course, if I'm using the webcam for something else, I'd need a way to have the script automatically detect it's in use, or to let me disable it, unless it can still run while I'm using the webcam for something else.
Basically I want to use this for help in tracking down thieves who might steal my laptop and try to fire it up. Somehow I'd like to snag the IP address and a webcam shot every 15 minutes, with about 2 days storage. Need color and 800x600 too.

I'm using FSC Lifebook S series, to be more specific S7210. I know from specs and from Win that it contains onboard accelerometer, in Win Vista it works perfectly, with FSC supplied "Motion sensor utility" it protects hard disk from damage during sudden shakes of notebook.
The question is - i couldn't anyhow find any note in Ubuntu that it is recognized and is used as it should be. So I'm wondering is it done automatically or it is not used at all? If it is working is there any way to check some status of it, or if it isn't how to get it to protect hdd?

I'm trying to create a bootable HFS+ partition. I've succeeded in creating the HFS+ partition in Windows using Mac Drive 8, but need to set the partition to "Active" to be able to install an OS on it. The issue lies that when I try to set it to active in windows disk management it tells me that the media has been write protected by Mac Drive. I want to either set the partition as active (or at least disable write protection to allow me to set it as active in windows) or find another means of creating an HFS+ partition, which I know gparted claims to do but I can't manage to enable it. I'm currently running Windows 7 but I have Ubuntu 9.04 Live CD to use if necessary.

In order to save power,I want to leave the default(blank) screensaver active,in case I forget to close my monitor when the computer is running.However,the screensaver is,by default,password protected and I would like to disable this annoying feature(which is,anyway,useless for me).If I go to System>Preferences>Screensaver and uncheck "Lock screen when scrensaver is active",will this remove password protection from the screensaver?

I'm setting up a fileserver for a client which will host their client invoices. They're looking for a system whereby invoices can be converted from RTF to PDF with copy protection (no right click / copy-paste). In addition to this I'm thinking of using a one-way hash to verify document integrity.
Are there any command-line utilities for Linux which allows adding this kind of copy protection / DRM to pdf documents?

I installed TrueCrype 6.3a on my 8.1 Ubuntu. Everything went fine until I got to the part where I need to protect my hidden volume from damaged caused by writing to the outer volume (these instructions: [url] ). I can't find the checkbox to "Protect hidden volume from damaged caused by writing to outer volume". The closest thing I can find is an option to "Protect hidden volume when mounting outer volume". Intuitively these don't sound the same to me. There are 2 difference between my setup and the instructions; 1) the instructions appear to be written for Windows and not Linux. 2) I am using a file volume and not a partition volume.
Does anyone know where the option is to protect the hidden volume when writing to the outer volume?

Because of a hard disk failure I had to buy a new disk and reinstall Ubuntu 10.04. Prior to the install I was running the live cd version of 10.04. When I connected to my wireless network and entered the password the key manager wanted me to enter a password to protect the network password. Now every time I boot up the system the network will not automatically connect. (It used to do this). Now I have to click on the network manager and select my network. When I do this I get the key manager asking for a password.
So how do I stop the key manager nonsense and get the network to connect automatically as it once did.

is there a way to make a password key-ring for a list of specifications, specifically; all the applications relating to preferences. I'm running Ubuntu 11.04, I'm the only user, I disabled all login password requirements because they were annoying me and I'm cool with anybody using any of my applications as long as they aren't capable of changing my system in any way. Some of the applications I would like to be on the list include the terminal, the network connections preferences, the keyboard preferences. I wan't to be prompted for a password before opening these programs
