...on a Fedora 17 x86_64 box with kde 4.9.3 (kchildlock version 0.90)

sorry for posting it also in the knowledge base, this is where it should be maybe?)

It is installed, the interface comes up and lets you define limits, apply and save them, export profiles etc... just as explained in the documentation, no warning at all. Both when launched from the system settings panel and from the command line as /usr/bin/kcmshell4 kcm_kchildlock --lang en_US


then when the users whose sessions should be time-limited log in, nothing at all happens. No system tray icon and above all no block /logoff or whatever else should happen after the specified time limits.

files **are** created in /var/lock/, with names like kchildlockd_20121214_094614_debuglog.tmp, but they have no effect at all. No warning is generated in any moment, and I can't find any log file anywhere related to kchildlock. Is this app working for others??? How to debug it?

Thanks,
M

Please try with latest version 0.90.4.2 and install the 32bit version.
If that does not work, please send me the debug files under /var/opt/kchildlock/ including .kch_time.dat and /usr/share/kde4/config/kchildlockrc*
and /root/.kde4/share/config/kchildlockrc*

Confirm.
On distros, who was migrated on systemd, dbus-query for consolekit don't work. It's need to be changed by query to logind.

Many thanks for your fine work on a much-needed application. It's straight-forward and intuitive, without sacrificing power and flexibility. I'm wondering if it would be possible to implement a "whitelist" feature, which would only allow certain programs to be run by a user, especially during a given time. Also, for the "Program Times" and "Program Duration" tabs, couldn't you give the option to add more programs than the imposed limit of five?

please install the 32bit Version of kchildlock. If the problem persists, you can enable a debug log. To enable the logging function of the daemon, create a file '/var/opt/kchildlock/kchildlockd__debuglog.tmp' with any content. The generated log files will be named like '/var/opt/kchildlock/kchildlockd_yyyymmdd_HHMMSS_debuglog.tmp'.
Have a look at that file, or send it to me.

I saw a download link for Chakra in a TXT in SourceForge. I just wanted to say that it links to the script used to create the package, but a binary package created with it exists in the official repositories.

Maybe this is a better link for users: http://chakra-project.org/packages/index.php?act=search&subdir=&sortby=date&order=descending&searchpattern=kchildlock

Hello,

my question is. Can I use kchildlock as a router software on Kubuntu ?
I like to make a router with firewall and proxy server with ip adress connected to mac-Adress.
So will be nice to take this software connected to a ip adresss or a group of ip adresses too.
So it will be a nice way to block the connection by time for my child.

Thanks for your reply...

Sorry, but this software can NOT be used as a router software. It basically does the checks on local interactive users of the PC.

In the meantime there is a package for kubuntu on sourceforge. I generated it on launchpad, and in the control file there is a line included with dependencies:
Depends: ..., cmake (>= 2.6.2-1ubuntu1 ), ...
It compiled without problem with this line.

The system I have kchildlock installed on is an older piece of hardware with limited memory.
I have the users running the icewm desktop because it uses less memory than KDE. KDE4 is installed.
I would like to have the daemon running no matter what desktop they select (KDE, gnome, icewm, etc).
I'm running openSuSE 11.2.

Is there some way to get the daemon to autostart for any environment? Perhaps copy/move one of the .desktop files to /etc/xdg/autostart?

I don't think this is possible yet. The daemon is tigthly coupled to KDE mechanisms.

SanityChallenged

OK, I thought that was the case, but wanted to check.
I hope you will be able to incorporate it with other desktops. Many people seem to like gnome, icewm, etc, also.

I'm using icewm on the machine in question because it doesn't use as much memory and the machine only has 512MB of ram.

Will keep checking and looking for a new release.
